Problems solved by technology

In the construction of existing water pipeline projects and pumping station projects, a relatively simple waterproof structure system is generally adopted when the pipeline passes through the exterior walls of underwater buildings. The hidden danger of water leakage at the root of the pipe, because the upstream surface of these parts has already been backfilled, the maintenance is time-consuming, laborious, high maintenance cost, and it is difficult to cure the water leakage, which affects the quality of the project

Embodiment Construction

[0018] The technical scheme of the present invention will be further described below in conjunction with specific embodiments,

[0019] The embodiment takes the Chaohe Pumping Station Project of the Huancheng Ecological Water Circulation Pumping Station Project in Zhengzhou as an example.

[0020] The diameter of the through-wall pipe 9 is 2000mm, the perforation diameter of the water-blocking wall is 2200mm, the outer diameter of the casing 7 is 2200mm, the inner diameter is 2100mm, the gap between the casing 7 and the through-wall pipe 9 is 100mm, and the thickness of the water-blocking wall 10 is 550mm;

[0021] First, a hole is made on the water blocking wall 10 to form a perforation for the through-wall pipe to pass through, and a water-stop steel plate 6 is arranged around the wall-penetrating pipe in the middle position of the water-blocking wall 10, and then a casing is inserted into the wall-penetrating pipe 9 to pass through. The gap between the casings 7 and the 2\3...

Abstract

The invention relates to a waterproof structure for a pipeline penetrating through an underwater outer wall. The waterproof structure comprises a water preventing wall and a through-wall pipeline. Thestructural system comprises three stages of waterproof structures which include the first-stage waterproof structure, the second-stage waterproof structure and the third-stage waterproof structure, wherein the first-stage waterproof structure is formed by putting water preventing filler to the position between a sleeve pipe and the through-wall pipeline; the second-stage waterproof structure is formed by an outer wall coiled material waterproof layer buried in polysulfide sealant; and the third-stage waterproof structure is formed by a pipe root coiled material waterproof reinforcement layercovering the outermost side.

Description

technical field [0001] The invention belongs to the field of water conservancy engineering construction, relates to a waterproof structure, and in particular relates to a waterproof structure for a pipeline passing through an underwater outer wall. Background technique [0002] With the continuous improvement of urban ecological water system construction, water delivery projects have gradually increased. In the construction of existing water pipeline projects and pumping station projects, a relatively single waterproof structure system is generally adopted when the pipelines pass through the outer walls of underwater buildings. The hidden danger of water leakage at the pipe root, because the upstream surface of these parts has already been backfilled, the maintenance is time-consuming, laborious, and the maintenance cost is high, and it is difficult to cure the leakage, which affects the quality of the project. SUMMARY OF THE INVENTION [0003] The purpose of the present ...
