Answer: it varies according to the model and elasticity of the grouting pipe, and its internal pressure can reach bar or more.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, the distribution of the internal stress field and displacement field of the reinforced soil mass is changed through the friction and embedment between the grouting pipe and the surrounding soil mass.Zaragoza square, specification: inner diameter of disposable grouting pipe: mm; Outer diameter: mm; Inner diameter tolerance: ± .mm; Length of each roll: m. Inner diameter of repetitive grouting pipe: mm; Outer diameter: mm Inner diameter tolerance: ± .mm; Length of each roll: m.Answer: it varies according to the model and elasticity of the grouting pipe, and its internal pressure can reach bar or more.Altamura,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, so as to select the grouting pipe. Grouting pipe at tensioning end: the grouting pipe installed at the end of the grouting pipe reinforcement and capable of tensioning is also called grouting pipe grouting pipe. The so-called grouting pipe is a grouting pipe in post tensioning structure or component to maintain the tension of the grouting pipe reinforcement and transmit it to the mixed tension; Fixed end grouting pipe: a grouting pipe installed at the end of the grouting pipe reinforcement and usually buried in the concrete without tensioning. The standard of the grouting pipe used for the grouting pipe reinforcement is the national standard of the people&#;s Republic of China (GB / T -,Zaragoza squareLeading small conduit manufacturer, which ensures that the products manufactured by our company conform to the product quality law of the people&#;s Republic of China and the standard law of the people&#;s Republic of China Grouting pipe is the only acoustic pipe specially used for ultrasonic testing in the market. The grouting pipe is made of cold and hard steel pipe after professional molding, and is connected by clamp pressure connection, screw connection, flange connection and other methods. It has a reliable anti-seepage effect during concrete pouring. Two convex grooves are planned at the end of the bell end of the high-strength double seal clamp type acoustic measuring pipe, and the convex grooves are equipped with sealing rings. When installing the device, the socket end of the product is stabbed into the bell end by cm, and then the two convex grooves are kneaded together with special hydraulic pliers. The pipe at the kneaded part is shortened and deformed after being stressed, and the outer pipe between the two convex grooves is deeply immersed into the inner pipe, and then the reliable connection of the product is completed; After being kneaded, the rubber sealing ring deforms and fits between the two layers of pipes, which significantly reduces its performance. During the use of the grouting pipe, it is forbidden to take any form of heating deformation measures to avoid reducing the mechanical properties of the grouting pipe.

The bottom of the horseshoe of the grouting pipe is too low. After the horseshoe is seated in the mold, the space between the outer mold and the horseshoe surface is greater than the thickness of the pipe wall. When reinforcing collapsible loess, sodium silicate solution with % sodium chloride and concentration of % ~ % is used. After the solution is pressed into the soil layer, sodium ions will react with calcium ions in water-soluble salts of the soil to form silicic acid gel between soil particles and on their surfaces, increase the cementation between soil particles and harden the soil. The ultimate compressive strength can reach . ~ .MPa. When strengthening the silty fine sand, a certain amount of phosphoric acid (density is added to the sodium silicate solution (density - with a low concentration. The solution is chemically reacted in the soil to harden the soil, and its ultimate compressive strength can reach .-.mpa.The arrangement of the strain gauge shall be installed before the prestressing force is applied, and the bracket shall be fully cooled when the initial reading is measured; If the prestress has been applied, it must be noted in the report that the supporting axial force data reflects the change of the stress of the grouting pipe after the prestress is applied.Sampling inspection, Action mechanism of grouting pipe: the grouting pipe is a flexible material. Under the action of soil load, it is a mechanism of dispersing the force on each hole belt and forming a resultant force.The research shows that the friction between the grouting pipe and the soil is also greatly related to the water content and compactness of the soil. The grouting pipe itself has a pattern and is also a grid like integral geo reinforced material, so the friction between the grouting pipe and the medium is very large; The grouting pipe also has a great tensile strength, a large deformation modulus, and the reinforcement is stable and uniform, which can see good results in a short time. It can be seen from the experiment that the mesh reinforcement performance of the grouting pipe is better than the strip reinforcement material, which increases the stability of the project; The grouting pipe is especially suitable for the construction of high-speed highways, because the action force of the back and forth traffic on the soil is very great, increase the deformation modulus of the soil, effectively enhance the strength of the soil, and achieve the effect of stabilizing the project and long-term use.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, the distribution of the internal stress field and displacement field of the reinforced soil mass is changed through the friction and embedment between the grouting pipe and the surrounding soil mass.

It is necessary to comprehensively consider the selection and configuration of grouting pipes, because there are many types of expansion joints, and correct selection is very important. Only in this way can the design of the piping system be safe, reasonable, reliable and economical.?Packaging strategyAnswer: Yes, it can be protected. The piston rod can be protected by adding plastic hoses or bellows within the travel range.The specification and weight of the grouting pipe are actually very well understood. It is the approximate method for calculating the weight of the grouting pipe per linear meter, and it is also the only correct algorithm that can be found now: the weight of the grouting pipe = . × (outer diameter of grouting pipe - wall thickness of grouting pipe) × Wall thickness of grouting pipe.The normal writing should be: w = . * s (D-S) where d = outer diameter s = wall thickness.If any crack is found, it shall be repaired in time, otherwise,Zaragoza squareTunnel leading small conduit and pipe shed, when the joint is deformed and subjected to water pressure, the ability of the grouting pipe to resist external forces will be greatly reduced. When positioning the grouting pipe, it must be kept flat at the interface, and the grouting pipe must not be allowed to roll or kink. If it is found that there is no twist, it should be adjusted in time. When casting and fixing the grouting pipe, the deviation of the grouting pipe shall be prevented, so as not to shorten one side and affect the water stop effect. When pouring and tamping the concrete, it must be vibrated sufficiently to prevent the poor combination of the grouting pipe and the concrete from affecting the water stop effect. The grouting pipe joint must be well bonded. If the construction site conditions are available, the method of hot vulcanization connection can be used.?Zaragoza square,Several common failures in the installation of grouting pipes always have many problems when using grouting pipes for work. In order to enable everyone to provide production to the factory normally, we have specially summarized the following failures that will occur when using grouting pipes. If you have problems in the following examples, you will know how to solve them The first point is that if the joint, nozzle or bottom of the grouting pipe is not tightly sealed, it will be blocked by cement slurry during construction. At this time, it is OK to check the sealing The second point is that the joint is misaligned or deformed during installation. At this time, we need to know that it is caused by the thin material selected. The above two points are common problems in the installation of grouting pipes that are not suitable for the current location. We&#;d better remember these points of attention, so that when they occur in the future, we will know how to deal with them to ensure a quick solution! The grouting pipe joint or the pipe orifice and the pipe bottom are not sealed tightly, so please bring in mud or cement slurry during the construction process to block the pipe: during the installation and grouting of the grouting pipe, the rebar is distorted or collided, causing the dislocation and deformation of the grouting pipe joint or the deformation of the pipe wall. The main reason for this is the selection of thin-walled grouting pipes.In China, the types of grouting pipes are relatively complete now, from grouting pipes and grouting pipes for Reinforcing Subgrade to glass fiber grouting pipes for highway pavement, to convex joint grouting pipes and plastic tensile grouting pipes for railway. For different road construction environments, which can not only ensure the quality of the road but also save the cost. So what kind of application effect can the grouting pipe achieve in highway maintenance? The grouting pipe manufacturer will take you to have a look.The main elastic element of the grouting pipe is the stainless steel grouting pipe, lateral and angular direction of the pipe by the expansion and bending of the grouting pipe.
