The method of making a hollow layer with observable structural leakage in the wall and bottom plate of underground engineering

Abstract

The method of making a hollow layer on the bottom plate of the wall surface of the underground project can observe the structural leakage, which solves the problems of waterproofing and structural maintenance of the underground project. Underground engineering is huge in size, and it is inevitable that there will be weak waterproof parts. At the same time, it will always be immersed in groundwater. Leakage, moisture, and condensed water will always exist. Even if a few more waterproof layers are made, these problems cannot be solved. The warranty period is not specified, and the waterproof principle on which the specification is based is flawed. The present inventor has made hollow walls and hollow floors without leakage performance in a large number of 15 years. Use drainage boards or other methods to make hollow walls and hollow floors, and then design openable cover plates. There are water storage tanks for structural water seepage in the sump wells, which can observe changes in structural leakage water and repair structural cracks in time to ensure The safety of the underground structure is a century-old plan; the double combination of structural maintenance and indoor hollow layer is the complete waterproof principle of underground engineering, which can make underground engineering permanently leak-free.

Description

1. Technical field [0001] The invention belongs to the construction method of waterproofing and drainage of the outer wall and the floor of the underground engineering structure. The plastic drainage board is used to make a hollow interlayer on the indoor wall surface of the outer wall of the structure and the floor of the floor, or to make a hollow in the underground engineering room by other methods. The interlayer can achieve drainage, moisture insulation, condensed water insulation, energy saving and heat preservation, and can also observe the water seepage of the outer wall and floor of the underground structure, so that the structure can be repaired in time to ensure the safety of the structure for a century. 2. Background technology [0002] Due to the huge size of the underground project, it is inevitable that there will be weak waterproof parts. At the same time, it will always be immersed in groundwater. Leakage, moisture, and condensed water will always exist. Even...

AI Technical Summary

Problems solved by technology

[0002] Due to the huge size of the underground project, it is inevitable that there will be weak waterproof parts. At the same time, they will always be immersed in groundwater. Leakage, moisture, and condensation will always exist. Even if a few more waterproof layers are made, these problems cannot be solved.

Therefore, the "Regulations on the Quality Management of Construction Projects" does not stipulate the warranty period for the waterproofing of underground projects, and the waterproofing principle based on the building waterproofing code is flawed.
