Description

Technical Field

[0001] The utility model relates to the technical field of bioretention zones, and more specifically, to a construction structure of a sunken bioretention zone for municipal roads in a sponge city. Background Art

[0002] Bioretention facilities refer to facilities that store, infiltrate, and purify runoff rainwater through plant, soil, and microbial systems in areas with relatively low terrain. Bioretention facilities are divided into simple bioretention facilities and complex bioretention facilities, and are mainly applicable to the surrounding green spaces of buildings, roads, and parking lots within buildings and communities, as well as urban green spaces such as urban road green belts.

[0003] Currently, during the construction of bioretention zones on municipal roads, a pebble layer is usually arranged inside the bioretention zone to play a role in initially filtering rainwater and filtering out large impurities. However, due to the relatively smooth surface of the pebbles and the lack of a structure to enhance the connectivity between the pebbles, the pebbles in the bioretention zone are prone to being lost for various reasons during the long-term operation, resulting in a reduction in the role of the pebble layer in initially filtering rainwater and filtering out large impurities, and further affecting the purification effect of runoff rainwater. In view of this, we propose a construction structure of a sunken bioretention zone for municipal roads in a sponge city. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide a construction structure of a sunken bioretention zone for municipal roads in a sponge city, so as to solve the technical problem that the pebbles in the current bioretention zone are prone to being lost for various reasons during the long-term operation, resulting in a reduction in the role of the pebble layer in initially filtering rainwater and filtering out large impurities, and affecting the purification effect of runoff rainwater.

[0005] To solve the above technical problems, the utility model provides the following technical solutions: A construction structure of a sunken bioretention zone for municipal roads in a sponge city, including a pebble filtration area with symmetrically detachable green planting areas at both ends, and a lane driving area arranged on both sides of the green planting area and the pebble filtration area;

[0008] The shoulder structure includes symmetrically arranged shoulder components. The shoulder components include symmetrically arranged curb stones b. A connecting block is integrally formed between the curb stones b, and a seepage trough for rainwater to flow in is formed between the curb stones b. Plug slots for inserting plug plates are equidistantly formed inside the connecting block. The plug plates are in a grille structure arranged obliquely, and the bottom ends of the plug plates extend to the bottom of the seepage trough.

[0009] The utility model designs a covering seat, a baffle and a sealing structure. By placing the covering seat on the shoulder structure, the cobblestone body can be covered, and the cobblestone body is blocked by the baffle, restricting the movement of the cobblestone body. At the same time, it avoids the situation that the cobblestone body is easily lost due to various reasons during the long-term operation. And the plugging cooperation between the plug plate and the plug slot is beneficial to the quick installation of the covering assembly and the shoulder structure.

[0010] Preferably, the greening planting area includes a planting soil layer, and a plurality of curb stones a are equidistantly arranged on both sides of the upper end surface of the planting soil layer.
