Appropriate measures shall be taken to prevent surface water, curing water and garbage from falling in. When necessary, a sump shall be set near the post cast strip of the base plate in combination with the design of the basement plane drainage system to facilitate the final cleaning before the grouting pipe is cast. When advance water stop is not used, a sump shall be set, which can be set in the basement according to the above method, or set outdoors as a temporary facility. Usually, we use the waterproof scheme between the grouting pipe and the water surface or before, and there are many methods for the grouting pipe to stop water in advance. It should be noted that the design unit should participate in the review of the construction organization design of the basement, so as to determine a complete implementation scheme of advanced water stop before the excavation of the foundation pit and the pouring of the cushion. Otherwise, the design modification requirements will be put forward only when problems are found in advance water stop during construction, which will affect the integrity and rationality of the whole water stop scheme.There are many forms of grouting pipes that can be improved and applied. Although the engineering pipeline system is very complex, any complex pipe system can be divided into several relatively simple individual pipe sections through the setting of fixed pipe racks. When selecting the corrugated grouting pipe, the deformation compensation of the pipe system can be determined according to these relatively simple pipe sections, so as to select the grouting pipe.Oshava,Oshava48lead small conduit,The headache formula for calculating the weight per linear meter of the grouting pipe is: (perimeter / - wall thickness) * wall thickness * . = how many kilograms per meter of the grouting pipe. This formula is a calculation formula trusted and recognized by most grouting pipe manufacturers. However, there will be some deviation in the calculation formula of the weight of the precise grouting pipe. Next I will tell you the actual application of several specifications.The grouting pipe with the grouting pipe as the core flexible element can be compensated in the axial, lateral and angular directions on the pipeline. From the perspective of its performance, the internal pressure grouting pipe can be displaced in three directions, but because it is limited by casing and other accessories, it can often only be displaced in the axial direction. Therefore, the user needs to indicate the displacement in several directions when selecting and ordering, so as to select correctly. The working principle of the grouting pipe is to use its own elastic deformation to compensate the axial, angular, lateral and combined displacement of the pipe due to thermal deformation, mechanical deformation and various mechanical vibrations. The compensation has the s of sealing, pressure resistance, temperature resistance, corrosion resistance, impact resistance, vibration reduction and noise reduction, which can reduce the deformation of the pipe and improve the service life of the pipe.Vidin, The saddle shaped curved surface on the horseshoe surface of the grouting pipe and the upper and outer molds are not well fitted, which is caused by the Chengdu grouting pipe manufacturer&#;s failure to smooth (flatten) the grouting pipe along the horseshoe surface. It has good air tightness, low gas permeability, strong sealing and no leakage.Among the many imported projects, the development of the production technology of automobile door and window sealing strips is the most representative. Through the introduction of sealing strip production lines from Japan,OshavaGrouting pipe leading small conduit, Germany, Italy, up to now, domestic manufacturers have introduced more than sealing strip production lines. In addition to pure rubber sealing strips sealing strips of various composite structures, rubber and plastic composite sealing strips can be produced. At present, and has become a grouting pipe. Because some projects are not easy to detect when they are manufactured, and the quality of the grouting pipe as a channel for testing instruments has become crucial. If the quality of the grouting pipe is poor, which has the characteristics of thin pipe wall, steel saving, impermeability, is generally used for post tensioned reserved holes in prestressed structures. When the grouting pipe is used, it can be directly bound to the reinforcement framework. Because the grouting pipe is very light, it is very convenient to operate. However, attention should be paid to the balance of its axis during installation.

The mesh structure of the grouting pipe can make the pore water pressure dissipate faster, and effectively accelerate the drainage and consolidation of the soft soil of the foundation. This is very important for strengthening soft clay foundation. Precautions for grouting pipe installation: when tensioning the prestressed reinforcement, it shall be loaded from zero to the initial tension at the starting point of the measured elongation value, and then loaded to the required tensioning force by stages; Stress control and elongation check shall be adopted for tensioning management of prestressed reinforcement. The allowable deviation between the actual elongation value and the calculated elongation value is - % ～ + %. If the value is exceeded, the tensioning shall be suspended; Tensioning can be continued only after taking measures to adjust; If the elongation value is too small, over tensioning measures can be taken, but the tensioning force limit shall not be greater than .fptk; In the multi wave curve prestressed reinforcement, in order to increase the tensile stress at the inner support and reduce the tensile stress at the lower mouth of the grouting pipe after tensioning, the technology of over tensioning and loosening can be adopted; The duct grouting shall be dense, and the strength grade of cement slurry shall not be lower than C. Before grouting, the duct shall be wet and clean, the grouting shall be carried out slowly and evenly without interruption, and the exhaust shall be smooth. If the hole is blocked, the grouting port must be replaced, but the cement slurry injected for the first time must be discharged to avoid gas between the two grouts. After the holes are filled and the exhaust holes are closed, the pressure should be increased to .-.mpa, and the grouting holes should be closed later. The grouting pressure of the vertical duct shall be determined according to the grouting height; For the duct grouting of multi span continuous prestressed tendons connected by connectors, one span shall be grouted after tensioning, and it is not allowed to grout once after all the spans are tensioned; The exposed length of the prestressed reinforcement grouting pipe after fixation shall not be less than mm, and the grouting pipe shall be protected with end sealing concrete. When it needs to be exposed for a long time, measures to prevent corrosion shall be taken; When the steel strand has floating rust, please remove the floating rust and dirt of the steel strand at the fixed clamping section of the grouting pipe and its outer end, so that the floating rust and dirt will fill the red groove of the clamping piece during installation and tensioning and cause wire sliding; The tool clamping piece is three pieces and the working clamping piece is two pieces. The two cannot be mixed. The working grouting pipe cannot be used as a tool and the grouting pipe cannot be reused; The grouting pipe shall be kept properly and shall be free of rust, water and other sundries during use. The working clip can be used after removing the foam in the packaging box. However, when the prestressed tendon is long and the grouting pipe must be repeatedly tensioned and fixed, it is recommended to apply a small amount of lubricant (such as withdrawing the grouting pipe) in the conical hole of the grouting pipe plate, which is not only conducive to the follow-up of the working clip and withdrawing the grouting pipe, but also conducive to the multiple grouting pipe fixation of the grouting pipe; The outer surface of the tool clip and the inner surface of the conical hole of the grouting tube plate shall be coated with lubricant before use and the debris on the clip surface shall be removed frequently to make the grouting tube flexible. However, when the clip is cracked or the tooth surface is damaged, it shall be replaced and shall not be used again; Safety measures shall be taken during tensioning, and no one shall stand after tensioning the jack; The grouting pipe solid system shall be used together and shall not be mixed with other systems. If the static load test is to be conducted, please clean the clamp with organic solvent (such as gasoline) and wipe the anti rust oil of the grouting tube plate hole, otherwise the solid performance of the grouting tube will be affected; The pile foundation grouting pipe is an important channel product for pile foundation depth detection. It has two main s, one is as a channel, and the other is as a pipe for grouting at the bottom of the pile.The disposable grouting pipe uses steel springs as the supporting framework, and is wrapped with a layer of non-woven filter cloth. The outermost layer is wrapped with nylon mesh, and can only be grouted once.In the engineering practice, some construction units directly pave the glass fiber grouting pipe after spraying the sticky layer oil and the roller rolls after it. The effect is good, and the glass fiber grouting pipe is not easy to wave. Strictly control the entry and exit of vehicles transporting the mixture, and forbid vehicles to swerve brake and dump the leftover mixture on the grouting pipe layer to prevent damage to the glass fiber grouting pipe; The back glue of glass fiber grouting pipe is easily soluble in water, and construction shall not be carried out in rainy days or wet roads; Glass fiber grouting pipe is made of grouting pipe, which is easy to irritate human skin. Construction personnel must wear protective gloves; When the grouting pipe is laid, the temperature of the road surface is required to be between . Therefore, the relative displacement trend or relative displacement will occur between the narrow two, which will then generate friction. This friction is generally called 'surface friction'.Quality inspection report, Low cost, fast time, no loss, free from climate and place constraints.Answer: Yes, the elastic extension speed of the grouting pipe can be defined within a certain range in the design, but for a grouting pipe that has been designed, its elastic extension speed is certain.General treatment method: first, yze what causes the pipe blockage. For the pipe blockage of hard objects, you can poke with steel bars according to the depth, or bind a slightly thicker steel bar with steel wire rope. For the pipe blockage of soft objects, you can use the air compressor pipe to open the air compressor for blowing. Be sure to note that the water in the pipe may rush up like a fountain to pour water all over you! If it is slurry leakage and pipe plugging, the grouting pipe can also be used as a pipe for grouting at the bottom of the pile. Experiments have proved that the bearing capacity of the cast-in-place pile treated with the grouting at the bottom of the pile can be greatly improved. At the same time such as low strain and core drilling method! Other uses of the grouting pipe: in addition to being used as a detection channel and replacing part of the reinforcement section, the grouting pipe can also be used as a channel for the defect washing and grouting treatment of the accident pile. At this time, it is necessary to take measures to punch through the pipe at the defective part to be grouted. Grouting pipe is specialized in the production of grouting pipe (ultrasonic detection pipe) for bridge pile foundation inspection. The product conforms to the industrial standard steel thin-walled grouting pipe for concrete cast-in-place pile and its use requirements (JT / T -, which was tried out by the Ministry of communications of the people&#;s Republic of China on April , It can not only meet the requirements of the standard, but also greatly improve each index, and obtain the inspection report of Hebei Road and Bridge Inspection Center.

The small editor of prestressed machines and tools will lead you to understand the main connection methods between the drive device and the wellhead: the connection between the flange of the drive head of the electric oil pump and the parallel flange is the most widely used one at present. There is a flange at the lower part of the drive head, and the size matches the flange of the Christmas tree wellhead.build,Answer: according to the length and diameter, the weight of common grouting pipe is . ~ .KG, and the weight can reach several kilograms.Application scope and development space of grouting pipe as a new term, grouting pipe has gradually appeared in some online newspapers and periodicals, and its practical scope has also developed from the support of some basic automobile boot and engine cover to the machinery manufacturing industry, used for the support of equipment accessories, support of tool box cover, medical industry, fitness equipment and other fields. As its practicality is further recognized, its scope of application is becoming wider and wider. Some people in the industry asked: the application range of grouting pipe is becoming wider and wider. Does it have an impact on the original telescopic spring? In my personal opinion, it will not impact the original spring. Of course, it will have a certain impact, because most of the grouting pipes are innovations in the product design of some enterprises. For example, the rear box of a tricycle was originally supported by an iron bar (which is still useful). Now, the grouting pipe is very light convenient and labor-saving. Some units do not know it, so its design has certain limitations, enterprises must be innovative in order to be ahead of their peers. We have been making grouting pipes for many years. Experience tells us that many manufacturers are now trying our grouting pipes, and they have been officially used, with obvious effects. However, some enterprises do not know what the grouting pipes are let alone their s, so they will be in a passive position. Therefore, we hope that some industries, such as machinery manufacturing, automobile and motorcycle, transportation equipment, box manufacturing such as tool boxes, medical treatment, fitness, kitchen cabinets, etc If you need to know the and use of the grouting pipe, please feel free to consult me, and I will give you adviceApplication scope: This product can be widely used in subway, tunnel, water plant and sewage treatment plant, swimming pool and upstream amusement park, dam, ship lock, c, reservoir and ditch, primary and secondary cofferdam facilities, bridges, commercial and industrial buildings, garages, stadiums, aquariums water tanks and similar structures. Grouting channel for deformation joint, construction joint leakage maintenance and embedded water stop. Slurry pipe (theoretical weight per meter)In limestone area, the punching is not good, and it is difficult to sink the reinforcement cage. When the grouting pipe is deformed and blocked by unconventional means, the pipe is blocked due to the workers&#; carelessness and falling into small concrete blocks. The deformation and blockage of the grouting pipe bring great difficulties to the detection work, and even can not be detected. Therefore, when the grouting pipe is found blocked after the foundation pile is poured and before the inspection, effective measures should be taken to pass the pipe to ensure the smooth progress of ultrasonic inspection. Generally, there are three methods for passing the pipe: stabbing the grouting pipe with thick and long reinforcement, and using a drill with a small drill to clean the hole.Oshava, After the two pipes are connected by using the deformation of the grouting pipe, the kneading part of the joint is large at both ends and small in the center, so that the joint is stuck at one time, avoiding the possibility of loose union. The grouting pipe has proper, stable and excellent s in terms of tensile pull-out and torque resistance, and the protrusion is circular arc with small protrusion, which is useful to avoid collision with conduits,OshavaSelf propelled hollow grouting anchor manufacturer, vibrators, etc.Disposal method: the grouting pipe shall be shortened according to the specification.The foundation pit excavation shall strictly follow the principle of 'layered excavation'. The support erection shall be closely coordinated with the earthwork excavation. During the excavation, the earthwork near the grouting pipe shall be excavated by the central trenching method to prevent the machinery from colliding with the support; The earthwork near the slope protection pile shall be excavated manually with small machines and tools. It is forbidden to collide with the grouting pipe and bored pile by mechanical excavation. After the earthwork is excavated to the design elevation, the grouting pipe shall be erected and prestressed in time to reduce the exposure time without support.
