Ecological tree pond system and construction method

Abstract

The invention discloses an ecological tree pool system. The system comprises a stereoscopic turbine rainwater fine-toothed comb, a double-wall corrugated pipe inspection well, arch regulation and storage equipment, a sludge discharging equipment, a grading soil layer, filament geotechnical cloth, a permeable blind pipe, grading fillers, an impermeable membrane, a gravel furrow, root-blocking porous plates and a connecting pipe, a foundation pit is dug in the tree planting position of a street of the urban road, the stereoscopic turbine rainwater fine-toothed comb, the double-wall corrugated pipe inspection well, the arch regulation and storage equipment, the sludge discharging equipment, the grading soil layer, the filament geotechnical cloth, the permeable blind pipe, the grading fillers,the impermeable membrane, the gravel furrow and the root-blocking porous plate are connected through the connecting pipe, and trees are planted in tree pits composed of the root-blocking porous plates. A construction method for the ecological tree pool system comprises the following steps of 1, construction preparation; 2, foundation pit digging; 3, geomaterial and grating filler laying; 4, installment of the arch regulation and storage equipment; 5, grating filler and grating soil layer laying; 6, gravel laying; 7, tree and green plant planting. The invention can effectively collect and store rainwater.

Description

technical field [0001] The invention relates to the technical field of sponge city construction, in particular to an ecological tree pool system and a construction method. Background technique [0002] Sponge city is a new generation of urban stormwater management concept, which means that the city has good "elasticity" in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called "water elastic city"; an international general term For "low-impact development rainwater system construction"; when it rains, absorb water, store water, infiltrate water, purify water, and "release" the stored water when necessary; so as to effectively reduce the impact of rainfall on urban drainage and The purpose of efficient use of water resources. In the existing urban construction, the use of rainwater is mainly when it rains, and the rainwater directly flows into the sewer pipe gallery through the road surface, and the pipe gallery store...

AI Technical Summary

Problems solved by technology

In the existing urban construction, the use of rainwater is mainly when it rains, and the rainwater directly flows into the sewer pipe gallery through the road surface, and the pipe gallery stores the rainwater. The purpose; the above will bring about a problem, the rainwater entering the sewer pipe gallery will cause deterioration and odor if it is not used for a long time

Furthermore, in the existing technology, for the cultivation and management mode of street trees, since there is no effective method to control the water and soil loss of cultivated trees during rainfall, it is necessary to ensure that the soil of cultivated trees is not exposed, and cement airtight The hard paving method isolates the soil surface of the roots of the trees from the outside world, which will block the communication between the roots of the trees and the outside air and water sources, resulting in the decline of tree growth
