Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering, in particular to a grouting device for PHC pipe piles. Background Art

[0002] PHC pile grouting refers to the process of injecting cement slurry, cement mortar or other grouting materials into or around the PHC piles (prestressed high-strength concrete piles) through specific methods and techniques during the construction process. The main purpose of this process is to improve the piles' compressive, tensile and horizontal force resistance, while enhancing the interaction between the pile body and the surrounding soil, thereby optimizing the safety and stability of the engineering structure.

[0003] At present, the existing PHC pile grouting device (according to patent number: CN217734030U) discloses a grouting device for PHC piles, the grouting device comprising: a spherical funnel, a first conduit fixedly connected to its upper end, and a second conduit fixedly connected to its lower end; a hose, an upper end of which is connected to a pump truck, a lower end of which is inserted into the first conduit and extends into the spherical funnel and is fixedly connected to the first conduit through a clamp; and a third conduit for extending into the PHC pile, the upper end of which is threadedly connected to the second conduit; wherein the third conduit comprises a plurality of pipe sections threadedly connected in sequence.

[0004] However, in the process of implementing the above technical solution, it was found that there are at least the following technical problems: during the grouting of PHC pipe piles, the device uses a catheter to extend into the PHC pipe piles for grouting. However, during the flow and solidification of concrete, it is affected by various factors, such as concrete ratio, construction technology, environmental conditions, etc., which may cause it to stick to the inner wall of the catheter. The sticky pipe wall will affect the grouting effect of the pipe pile, thereby causing the pile body quality to fail to meet the standards and affecting the stability of the overall project. Therefore, in order to solve the above problems, we propose a grouting device for PHC pipe piles. Utility Model Content
