Description

Ecological corridor grit chamber structure with runoff pollution reduction function Technical Field The utility model relates to the technical field of grit chambers, in particular to an ecological corridor grit chamber structure with a runoff pollution reduction function. Background The urban ecological corridor is used as a banded region in the urban ecological environment, has the functions of optimizing the biodiversity protection pattern and communicating the biological habitat, is an important part of a scale ecological network of the urban area, and is a key link for guaranteeing ecological safety and improving resident welfare of the urban area. The urban ecological corridor is divided into a river ecological corridor, an urban road ecological corridor and an urban green space ecological corridor. In recent years, along with the promotion of the sponge city concept, in order to enhance the effect of the city corridor in urban rainfall flood management, the city corridor is taken as an important ring in a city sponge system, and the main aim is to relieve waterlogging in the peripheral area of the corridor and improve the capability of coping with extreme rainfall on the basis of absorbing own runoff. Because the traditional city development and construction uses the standing stone as a main part, rainwater on the periphery of the ecological corridor is difficult to enter the corridor, and the sponging of the urban ecological corridor is realized, the peripheral area of the corridor and the surface runoff route of the corridor are opened through the transformation of the opening of the curb, the rainwater runoffs in the peripheral area are collected, after preliminary sand setting and purification are carried out, the green space is utilized to build a submerged sponge facility, and the on-site storage, purification and absorption of rainwater are realized, so that the natural storage, natural permeation and natural purification of rainwater are realized, and the rainwater and flood management function of the urban ecological corridor is exerted. Existing curbs include the following categories: 1. opening type curb: The design form is that rectangular or trapezoid gaps (the width is usually 20-30cm and the interval is 5-15 m) are formed on the side face of the curb at intervals, the bottoms of the gaps are level with or slightly lower than the pavement, and pebbles or ecological concrete are paved at the gaps to prevent scouring. The method is suitable for the junction of green belts, sidewalks and greenbelts between the motor vehicle lanes and the non-motor vehicle lanes. The method has the advantages of low cost and simple construction, and is suitable for the transformation of the existing road. 2. Concave kerb: The design form is that the whole height of the curb stone is reduced (for example, the curb stone is reduced to 5cm from 15 cm), the top and the road surface form a height difference, rainwater can overflow into a green land, and a crushed stone layer is arranged at the bottom to enhance penetration. The method is suitable for the areas adjacent to roads and sunk greenbelts and biological detention ponds. The natural overflow is realized, and the manual maintenance is reduced. However, the existing curb reconstruction method still has some technical, economical and maintenance disadvantages and drawbacks in practical application, and is specifically as follows: (1) The problem of rainwater drainage is that the silt is easy to block due to the overlarge opening, the diversion capacity is insufficient due to the overlarge opening, excessive rainwater cannot be rapidly discharged during extreme rainfall, and the hidden danger of waterlogging can be thoroughly solved by energy supplementing. (2) The runoff pollution problem is that the periphery of the ecological corridor is mostly urban roads, so that suspended particulate matters, dirty oil, heavy metal pollutants and the like on the road surface are more polluted, and if rainwater is directly introduced into the ecological corridor, the pollutant load of the corridor can be increased. (3) The durability of the material is that the cement brick material has insufficient strength, the permeable kerbstone is easy to be blocked, and the pores of the porous material are blocked by silt and pollutants after long-term use. (4) The maintenance cost problem is that the diversion trenches of the open curb need to be frequently cleaned with fallen leaves and garbage, and the later-stage reconstruction and maintenance difficulty is high. Disclosure of utility model The utility model aims to solve the problems in the prior art and provides an ecological corridor grit chamber structure with a runoff pollution reduction function. In order to achieve the above purpose, the present utility model adopts the following technical scheme: Ecological corridor grit chamber structure with runoff pollution reduction function includes: The first installation seat is
