Sponge city ecological footpath

Abstract

A sponge city ecological footpath comprises compound grass-planting bricks, a lawn layer, a fine sand layer, a first ripped-rock layer, an original soil layer, fixing blocks, a second ripped-rock layer and cylindrical mortise and tenon joint structures; each of the compound grass-planting bricks comprises a substrate layer and a porose concrete layer, the lawn layer is laid in the compound grass-planting bricks, the fine sand layer is laid under the compound grass-planting bricks, and the first ripped-rock layer is laid under the fine sand layer; the compound grass-planting bricks, the lawn layer, the fine sand layer and the first ripped-rock layer form a base layer, and the fixing blocks are arranged at the two sides of the base layer and are provided with the cylindrical mortise and tenon joint structures along the direction of a road. The sponge city ecological footpath provided by the invention has the advantages that the construction period is short, the structure design is reasonable, two or three persons can simultaneously walk thereon, the length can reaches any required positions; the maintenance is convenient, the nutrition of greening vegetation is balanced, and the footpath repair efficiency is high; the fixing blocks are connected with one another tightly, so the collapse of the footpath is avoided, and when meeting a heavy rain, water can be quickly absorbed and stored to realize water seepage and water purification.

Description

technical field [0001] The invention belongs to the technical field of sponge city construction, and in particular relates to a sponge city ecological trail. Background technique [0002] Sponge city is a new generation of urban stormwater management concept. It refers to the city's good "elasticity" in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called "water elastic city". The international general term is "low-impact development stormwater system construction". When it rains, it absorbs, stores, infiltrates, and purifies water, and "releases" the stored water for use when needed. [0003] At present, when the heavy rain comes, the permeable pavement cannot quickly absorb and store water, resulting in a large amount of rainwater loss, thus failing to achieve the purpose of water seepage and water purification, and may cause huge disasters. [0004] Ecological trails are often used in garden landscapes. Ecologi...
