AI Technical Summary
Technical Problem
Existing waterproofing devices for deep underground buildings cannot effectively control the flow of water when leaks occur, leading to irregular water flow and easy erosion of large areas of the walls.
Method used
It adopts a bottom waterproof structure, a flow channel design between the outer and inner waterproof walls, and combines a water collection tank, a pumping system and a ventilation system. It uses a photovoltaic power supply system to provide energy to achieve orderly water flow and pumping.
Benefits of technology
It effectively reduces the contact between seepage water and the internal waterproof wall, reduces unnecessary losses, improves waterproofing effect, and ensures the dryness and safety of the structure.

Abstract
This utility model provides a waterproofing device for deep underground buildings, including a bottom waterproofing structure, an outer waterproofing wall, an inner waterproofing wall, and a waterproof partition structure. The bottom waterproofing structure is located at the bottom between the outer and inner waterproofing walls. The outer waterproofing wall is located outside the inner waterproofing wall. A cavity is formed between the bottom waterproofing structure, the outer waterproofing wall, and the inner waterproofing wall. A water collection tank is provided on the bottom waterproofing structure. The opening of the water collection tank is lower than the cavity and the upper surface of the bottom waterproofing structure, and is connected to the cavity. The overall design of this utility model allows for timely diversion of water into the water collection tank via a diversion channel when water seeps into the wall. The water is then pumped out by a pumping system. This avoids irregular flow of the seeping water and minimizes contact between the seeping water and the inner waterproofing wall, thereby reducing unnecessary losses.
