Tree root type basement

Abstract

The invention discloses a tree root type basement. The tree root type basement comprises at least two basement units located under an upper-layer building, a connecting layer between any two adjacentbasement units is a natural soil layer, and the basement units comprise basement bodies of a multi-layer structure and anti-seepage structures surrounding the side walls and bottom plates of the basement bodies. According to the tree root type basement, the basement is divided into a plurality of small basement units occupying smaller area in a partition mode, the basement units are located underthe upper-layer building, the natural soil layer is arranged among the basement units, the basement units are connected with the upper-layer building and a traffic core, the functions of the basementinclude but are not limited to an equipment room and a stereo garage. By the adoption of the root type basement, the soil layer around the building can give full play to the permeation effect and themoisturizing effect, the direct surface runoff path around the building is shortened, runoff pollution is reduced, and the pressure of a drainage pipe network in an urban core area is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a tree root type basement. Background technique [0002] Sponge City Construction—Low Impact Development The construction of rainwater systems is crucial to urban drainage and flood prevention systems. Its basic principles are planning guidance, ecological priority, safety first, adapting measures to local conditions, and overall planning of construction. At present, the sponge city controls the annual runoff and runoff pollution of the site through natural and artificial infiltration, storage, evaporation, etc. The main technical measures include permeable pavement, sunken green space, rainwater storage, rain garden, ecological grass ditch , filter tree ponds, artificial wetlands, etc. Although the current technical measures of sponge city can effectively alleviate urban waterlogging, reduce urban runoff pollution load, save water resources, protect and improv...

AI Technical Summary

Problems solved by technology

Although the monolithic basement solves the functional and space problems of the supporting facilities of the project, it also creates some urban problems: firstly, the monolithic basement cuts off the connection between the ground and the surface, making the surface runoff unable to infiltrate directly, and needs to be guided to the The basement area is infiltrated and stored, which will greatly increase the runoff path and runoff pollution

Secondly, the covering soil on the roof of the basement is generally 1.0 to 1.5 meters. Large trees cannot be planted, and the soil’s water and soil retention capacity is also weak. As a result, the root growth of the green vegetation above the basement is restricted, and the role of green protection and ecological environment improvement cannot be fully utilized.
