Construction method of novel greenbelt structure based on sponge city

Abstract

The invention discloses a construction method of a novel greenbelt structure based on a sponge city. The construction method comprises the steps of 1, sorting a planting layer; 2, building an impounding reservoir; 3, storing water for the ground in place; 4, burying a negative well; 5, laying bricks; 6, arranging a control chamber; 7, arranging a probe; 8, conducting greenbelt planting and daily management. The construction method is easy in construction, low in difficulty and ordered in construction, the construction quality is easy to control, less construction equipment is needed, the construction cost is low, the permeation effect is good, water-permeable bricks and water-permeable concrete are laid, so that rainwater quickly infiltrates, the excess infiltration part enters a greenbeltarea, plants in the greenbelt hold up rainwater, and the retention time of the rainwater in the greenbelt area is prolonged.

Description

technical field [0001] The invention relates to a green space construction method, in particular to a construction method based on a sponge city-based novel green space structure. Background technique [0002] With the advancement of urbanization, the increase of ground hardening has changed the original hydrological characteristics, resulting in increased rainwater runoff, frequent water accumulation on the road surface, and frequent large-scale water accumulation in some cities. The drop in groundwater level has intensified. In addition, the problem of water shortage in my country's cities is becoming more and more serious. The resource-based water shortage in the northern region and the water quality-based water shortage in the southern region. In this environment, the government proposed the goal of building a "sponge city" and supported it in various aspects such as policy and finance. [0003] Sponge city, as the name suggests, is like a sponge. During the rainy peri...

Problems solved by technology

Whenever there is heavy rain, it mainly relies on "grey" facilities such as pipes, canals, and pump stations to drain water. The main planning and design concepts are "quick drainage" and "end-centralized" control. Rainwater is mainly drained through drainage facilities and cannot penetrate into the ground. It will cause waterlogging every time it rains, and the drought and flood will turn sharply, which does not meet the requirements of sponge city construction
