Pile head waterproof structure and construction method thereof

Abstract

The invention discloses a pile head waterproof structure and a construction method thereof. A waterproof roll is laid first, then a post-pouring pile head is formed through pouring, the waterproof roll and the post-pouring pile head are formed into a whole, a buffer rod is arranged at the end of the post-pouring pile head, thus the waterproof roll can settle along with settlement of the post-pouring pile head, the conditions that the waterproof roll is stressed and torn due to settlement of the pile head are avoided, and waterproof integrity and reliability are ensured. A settlement sealing strip is of a special structure, and under extrusion of the post-pouring pile head, inside sealant is extruded continuously to seal the waterproof roll, a foundation pile head and the post-pouring pilehead. In addition, along with settlement of the building, extrusion pressure of the post-pouring pile head becomes large, more sealant in the settlement sealing strip is extruded, thus the waterproofroll and the pile heads are sealed more tightly, water prevention is more reliable, and a virtuous cycle is formed accordingly. The pile head waterproof structure and the construction method thereof provided by the invention are suitable for cast-in-place piles, precast piles, hollow piles and other various pile heads of different models and shapes and are high in practicability.

Description

technical field [0001] The invention relates to the technical field of building waterproofing, in particular to a pile head waterproofing structure and a construction method thereof. Background technique [0002] The basement is an important part of our country's architecture. With the development of society, the density of the city continues to increase, and the use of basement projects such as underground civil air defense, underground shopping malls, underground warehouses, and underground parking lots is becoming more and more extensive. The depth and number of floors of the basement It is also constantly increasing and expanding. The general leakage problem of the basement has always been a pain point for the quality of the basement project. inconvenient. [0003] There are many reasons for the leakage of the basement, among which the key and key is the leakage of the pile head in the basement. For the leakage of the pile head in the basement, many solutions have been ...

AI Technical Summary

Problems solved by technology

And the invention patents whose publication numbers are CN 208763074 U, CN 207959291 U and CN 205475361 U all involve the pile head waterproof treatment technology, but they all fail to solve the problem of waterproof failure at the pile head caused by the settlement process of the building

[0004] The main reason for the leakage at the pile head of the basement is the failure of the waterproofing at the pile head caused by the building settlement process, which is caused by the infiltration of groundwater, and the current building settlement is unavoidable
