Three-dimensional grid water drainage device

Abstract

The invention provides a three-dimensional grid water drainage device and relates to the technical field of water supply and drainage. The three-dimensional grid water drainage device comprises a three-dimensional grid, an open caisson and an open caisson protective wall; after seeping into the three-dimensional grid through a soil mass, surface water flow can be drained through an internal spaceof the three-dimensional grid water drainage device; and sediments in the water flow out to the open caisson from a bottom side grid hole of the three-dimensional grid and are deposited in the open caisson. According to the three-dimensional grid water drainage device, by using the surrounding water permeability of a grid structure, surface water can directly seep into the grid hole through the soil mass so as to increase the water drainage speed when rapid water accumulation situation is caused in stormy weathers and the like. A bottom plate of the three-dimensional grid water drainage devicealso possesses water permeability so that the water mass on the upper side of the highest underground water level cannot be completely lost; and therefore, the water storage capacity in the soil massis effectively guaranteed, a water storage effect is achieved, and an idea of a sponge cavity is realized.

Description

technical field [0001] The invention relates to a three-dimensional grid drainage device, in particular to the technical field of water supply and drainage, and realizes the concept of a sponge city of drainage. Background technique [0002] With the acceleration of urban construction, the problem of urban water accumulation has increasingly plagued the comfort of urban life. There are often two problems in the drainage devices in residential and leisure places such as residential quarters and parks: first, the drainage capacity is not strong, causing water accumulation in the residential area; second, the drainage speed is too fast, and the moisture content of the soil is low, resulting in poor vegetation growth conditions. [0003] With the continuous advancement of science and technology, many new hard and corrosion-resistant materials are used in reality, such as sidewalk tree pit grid panels, which have the characteristics of high strength, corrosion resistance, and lig...
