Double-curved-surface cave depot waterproof and drainage system and construction method

Abstract

The invention discloses a double-curved-surface cave depot waterproof and drainage system which comprises a tank chamber dome plastic drainage plate, a tank chamber side wall waterproof and drainage plate, a tank chamber platform plastic drainage plate and a tank chamber bottom plate drainage plate, drainage blind pipes are arranged in all the drainage plates, and eight dome radial drainage plates are arranged on the tank chamber dome plastic drainage plate. A vertical plastic drainage plate above the platform and a vertical plastic drainage plate below the platform are arranged on the tank chamber side wall waterproof and drainage plate, a platform annular drainage pipe and a transverse plastic drainage plate are arranged on the tank chamber platform plastic drainage plate, and the platform annular drainage pipe is embedded between the vertical plastic drainage plate above the platform and the vertical plastic drainage plate below the platform. A radial drainage blind pipe, an annular drainage blind pipe, a bottom plate annular drainage blind pipe and a bottom plate radial drainage blind pipe are arranged on the tank chamber bottom plate drainage plate. The drainage inspection well has the beneficial effects that infiltrated underground water can be effectively collected and discharged into the drainage inspection well below the inlet bottom plate through the arranged drainage plate, so that the external water pressure of the tank chamber lining is reduced.

Description

technical field [0001] The invention relates to a hyperboloid cavern waterproof and drainage system and a construction method, belonging to the technical field of drainage structures. Background technique [0002] With the development of modern society, underground engineering has become an important part of promoting the steady progress of society. It is not only used for transportation, hydropower, etc., but also in modern city construction, refrigeration, oil storage, water storage, environmental engineering and national defense engineering, etc. played a huge role in. However, due to the complex and changeable underground conditions, there have always been various problems in the construction of underground projects. Among them, the problem of waterproofing and drainage has always been the focus of underground projects. Especially in southern China, it is rainy throughout the year, the climate is humid, and the groundwater is abundant. The construction has brought many ...

Problems solved by technology

However, due to the complex and changeable underground conditions, there have always been various problems in the construction of underground projects. Among them, the problem of waterproofing and drainage has always been the focus of underground projects. Especially in southern China, it is rainy throughout the year, the climate is humid, and the groundwater is abundant. The construction has brought many inconveniences, among which the chemical substances rich in groundwater have seriously affected the stability and durability of underground projects

[0003] The existing waterproof and drainage technology for underground engineering is mainly aimed at tunnel cavities. The applicability of the waterproof and drainage construction for underground tank chambers is poor, and it cannot effectively achieve the desired effect. Especially for hyperbolic spherical domes, the existing waterproof and drainage technology There are many shortcomings, and there is no systematic waterproof and drainage system and construction method, so it is difficult to guarantee the waterproof and drainage effect
