a water retaining device

Abstract

A water-retaining device, characterized in that: it includes a first water-retaining area arranged on the ground; one side is connected to one side of the first water-retaining area, and the other side can The second water retaining area rising upward from the first water retaining area; and connecting the first water retaining area and the second water retaining area to set the first water retaining area and the second water retaining area Spatial boundary setting zones that accommodate space boundaries generated between zones. In order to prevent the water flowing into the accommodation space from flowing into the second space from the joint area of ​​the first and second water blocking areas, the space boundary setting area and the first water blocking area and the second blocking area The water zones are joined using high-frequency dielectric heating bonding technology. The water retaining device of the present invention has the advantages of simple and convenient structure, convenient and reliable operation, wide application places and strong practicability.

Description

technical field [0001] The invention relates to a water retaining device, in particular to a water retaining device capable of timely responding to emergencies caused by heavy rainfall. Background technique [0002] Usually, underground facilities such as subways, underground passages, underground shopping malls, and underground floors of buildings are mostly located tens of meters below the ground. The purpose of building these underground facilities is to save the increasingly narrow and complex above-ground space. [0003] For the convenience of users to freely enter and exit, the aforementioned underground facilities at a certain depth from the ground are usually provided with multiple entrances and exits. [0004] The entrances and exits of the above-mentioned underground facilities are usually equipped with surface steps with a certain width and a height of 10-20m above the ground. There are downward-sloping steps or escalators between the entrances and underground fac...

AI Technical Summary

Problems solved by technology

However, the existing water retaining method requires constant flood control water retaining plates around the entrances and exits of underground facilities, and additional guides and fixing devices are required to fix the flood control water retaining plates, which is very inconvenient to use

[0008] At the same time, the existing flood control baffles can only act as dams at the entrances and exits of underground facilities, and cannot meet the water retaining needs of small reservoirs and temporary storage dams. Advanced and perfect water retaining devices should not only be installed at the entrances and exits of underground facilities as dams In addition, it can also take into account the water retaining needs of small reservoirs, temporary storage dams, etc.
