A short section of screw end rod is welded on both ends of a single prestressed thick steel bar, and the nut and backing plate are sleeved to form the simplest grouting pipe. The pretension force is transmitted to the nut through the bearing force on the threaded slope of the screw end rod, and then to the concrete components around the reserved hole crossing through the base plate.Let&#;s take a look at the prestressed machines and tools. The small editor of prestressed machines and tools reminds everyone that the screw end rod is made of cold drawn or heat-treated reinforcement, and the thread is fine teeth. The welding between the end rod and the prestressed reinforcement should be carried out before the cold drawing of the prestressed reinforcement. This grouting pipe can be used at the tensioning end and the fixed end. A general jack is used for tensioning,MalakatanTunnel leading small conduit and pipe shed, and the jack pull rod (with internal thread at the end) is tightened on the thread of the screw end rod for tensioning. After tensioning, tighten the nut and anchor the rebar. The advantages of this grouting pipe are relatively simple, and when the jack returns oil after the grouting pipe, the prestressed reinforcement basically does not slide. If necessary, facilitate re tensioning. The disadvantage is that the accuracy of the length of prestressed reinforcement is high, and it cannot be too long or too short, otherwise the thread length is not enough.The glass fiber grouting pipe is a rigid product made of high-strength alkali free peeling fiber which is made into a mesh base material through an internationally advanced fine knitting process and is surface coated. Unidirectional tensile plastic grouting pipe is a grouting pipe made of high-density polyethylene (HDPE) as raw material, plasticized and extruded plate, punched, extruded and pressed, and then punched with regular hole network, and then stretched longitudinally. In this process, the polymer is in a directional linear state and forms an oblong reticular integral structure with uniform distribution and high node strength. The tensile strength and rigidity of the grouting pipe are fully improved through the reorientation of the originally scattered chain molecules into a linear state by stretching.Malakatan, those skilled in the art can make various improvements and modifications on the basis of the above embodiments, and these improvements or modifications fall within the protection scope of the utility model. Those skilled in the art should understand that the above specific description is only for the purpose of explaining the utility model, and is not intended to limit the utility model. The scope of protection of the utility model is defined by the claims and their equivalents.When the grouting pipe is laid, it shall be kept flat and tight without wrinkling, so that the grouting pipe has effective tension. After laying, it shall be rolled again with a clean steel wheel roller. Most urban roads use glass fiber grouting pipes with self-adhesive. The diameter of the glass fiber grouting pipe is . ~ times of the maximum particle size of the asphalt concrete surface aggregate. The ultimate tensile strength should be greater than kN / m, so as to give play to the anti reflection crack performance of the glass fiber grouting pipe. It can also ensure the shear resistance and adhesive force of the adhesive layer of the glass fiber grouting pipe.Maine-Soroa,The stability of the grouting pipe is one of the important factors to control the stability of the whole foundation pit. Its erection must be accurate and in place and prestress must be applied in strict accordance with the design requirements. In particular, attention should be paid to the stability of the diagonal bracing. During the diagonal bracing operation, every link of the installation must be carefully operated. At the same time, the steel purlin must also ensure its stability, strength and deformation requirements during the production and installation process. In addition, During the whole construction process from foundation pit grouting pipe erection to removal, the grouting pipe must be strictly monitored to ensure its stability. How to improve the bearing capacity of piles with grouting pipes in bored piles, during the drilling process of large-diameter cast-in-place piles, the soil layer around the piles will become loose due to the agitation of the turning heads. In addition, the water immersion makes the soil layer that has started to loosen more loose. This problem can be effectively solved by grouting with grouting pipes. How to improve the bearing capacity of piles when grouting with grouting pipes?The grouting pipe diffuses the load on it. When the reinforced soil is loaded, the grouting pipe has a high bond with the soil, and has a mutual embedding effect with the soil, showing better tensile performance. The tensile stress of the soil is transmitted to the grouting pipe, making the reinforced soil a tensile member, which can change the stress from the vertical direction to the horizontal direction spread the load stress evenly to a large base range, enhance the overall tensile strength of the soil, and effectively improve the stress distribution of the pavement structure. The strength of high tensile reinforced soil is far higher than that of unreinforced soil, greatly improving the bearing capacity of the soil.When the pipe cannot be connected due to serious blockage, core drilling detection must be carried out; when it is not the first pile of a certain bridge, the construction unit shall apply for changing the detection method The low strain reflection wave method or high strain strain strain measurement method shall be used and signed by the supervisor&#;s representative and the person in charge of quality supervision before implementation; In case of pipe blockage of a bridge for many times, core drilling inspection shall be carried out in due time. Common problems and answers of grouting pipe what is the pressure inside the grouting pipe?

The main elastic element of the grouting pipe is the stainless steel grouting pipe, which compensates the axial, lateral and angular direction of the pipe by the expansion and bending of the grouting pipe.After checking that the formwork installed by the grouting pipe is tight and seamless, the reserved groove can be cleaned, and then the concrete can be poured and vibrated tightly. The concrete shall have at least the same strength as the structural concrete at this place. The grouting pipe device in Hainan shall be kept clean when pouring concrete. It is a thermoplastic material, which can be processed and formed many times, providing convenience for hot melting and electrofusion connection of pipes.Discount, It is applicable to the laying of buried pipes in gas pipeline projects, and is not applicable to the use of open pipes. The service life of pipes will be affected by the perennial ultraviolet corrosion of sunlight. How to use the grouting pipe after rusting will not affect its . The grouting pipe is a kind of rubber plate we often see. It is widely used and has a long service life. It has been praised and recognized by people. Next, I will introduce the relevant knowledge of the grouting pipe we produce in detail! After the two pipes are connected by using the deformation of the grouting pipe,MalakatanPrice of advanced small conduit, 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, vibrators,MalakatanLeading small conduit manufacturer, etc.Answer: Yes, it can be protected. The piston rod can be protected by adding plastic hoses or bellows within the travel range.

The important reason for the stability of the grouting pipe reinforced soil subgrade is to further verify the main principle of the grouting pipe reinforced soil subgrade treatment technology. It is to place various types of grouting pipe products inside, on the surface of the soil mass or between the layers of soil mass. Relying on the tensile characteristics of the grouting pipe,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. Post grouting: after the shaft, tunnel, basement and other structures are dug, the grouting method is used to control water damage and strengthen the stratum which is called post grouting.When the grouting pipe is laid, it shall be kept flat and tight without wrinkling, so that the grouting pipe has effective tension. After laying, it shall be rolled again with a clean steel wheel roller. Most urban roads use glass fiber grouting pipes with self-adhesive.

How to improve the bearing capacity of piles when grouting with grouting pipes?They shall be connected as a whole in the factory as far as possible. If it is necessary to connect on site due to manufacturing process, transportation conditions, hot press vulcanization (grouting pipe) or welding (plastic grouting pipe) shall be used. The joint appearance shall be smooth and smooth, and the tensile strength shall not be less than % of the base metal. The so-called 'overlapping' without any treatment is absolutely not allowed. All kinds of cross connection points of grouting pipes shall be made of accessories produced by our new rubber products factory, so as to ensure that on-site connection is only carried out in straight sections during construction. Flexible material with sufficient deformation capacity and good adhesion with concrete.In the process of using the acoustic pipe, it is necessary to have a detailed understanding of its installation method, so that it can be used normally and improve the application quality of the grouting pipe. In the process of installing Jiangsu acoustic measuring tube, we should pay attention to the orientation of the installation hole. As long as the device is installed in a correct hole, the Jiangsu acoustic tube can be used normally in the process of application, and the service life of Jiangsu acoustic tube can be improved. This is also the most important factor in the process of application in the future. If the hole fault is bragged about in the process of the device, the resistance of Jiangsu acoustic pipe will appear in the process of application resulting in its damage. There is a great relationship between the accuracy of the hole and the quality after construction. In the process of construction, it is necessary to use the device according to the planned paper so that it can be used normally and improve the quality of use.In the process of application, because there will be many Jiangsu acoustic measurement pipes in the process of construction. In this way, the phenomenon of uneven stress will be formed. In the process of application, the phenomena of conflict and unusable will be formed. In order to prevent the phenomenon of surrounding each other, it is necessary to pay attention to the method of the device in the process of the device, so that it can be used normally. The grouting pipe manufacturer introduced that the product quality of the grouting pipe is relatively stable, and when the mold is finalized, it is not easy to show defects. Most of the defects of the grouting pipe appeared in the trial production period, and most of them were formed due to the unreasonable planning structure of the mold. The grouting pipe manufacturer will briefly introduce the treatment methods of defects as follows: wrinkle appearance and treatment methods. The so-called wrinkle refers to that there is a convex edge on the circular arc surface of the grouting pipe, and there is a concave appearance on the adjacent side. This kind of wrinkle is mostly in the shape of sharp ridges, some of which are straight to the nozzle, and often occur symmetrically at both ends of the center line, in the shape of 'eight'. Chengdu grouting pipe manufacturers mostly occur on the inner arc surface, and some occur on the outer arc surface.
