Embodiment 1

[0111] The second phase of the road project (K0+510.000~K1+441.699) of Xuetang Road, Yuelai New Town, Liangjiang New District, Chongqing, undertaken by our company, starts from the stake number K0+510.000 of Xuetang Road and extends to the north, connecting with Zhongli Road, Jia After the level crossing of Lan Road, it terminates on the north side of Jialan Road. The terminal stake number is K1+441.699, and it is 931.699m long. It is a two-way six-lane road with a width of 36m. Sidewalks on both sides are 6m wide. As one of the national sponge city construction pilots, this project is in accordance with the national sponge city construction requirements, according to the Ministry of Housing and Urban-Rural Development's "Technical Guidelines for Sponge City Construction - Low Impact Development Rainwater System Construction (Trial)" and other technical regulations and related management methods, combined with Based on comprehensive research and analysis of the actual situatio...

Abstract

The invention provides a urban road greenbelt LID (low impact development) bioretention trough construction method. The construction method sequentially comprises the following steps: excavating grooves and pits; installing a plastic product inspection well and a municipal pipe network connecting pipe; implementing concrete trench wall construction; paving sand on a basement; paving an impermeable membrane; paving and adding a pebble bed; installing an HDPE (high-density polyethylene) perforated pipe and filling the perforated pipe with pebbles; paving and illuminating a permeable geotextile on lower layer; adding and paving a sand filter bed; paving and illuminating a permeable geotextile on upper layer; installing curbs at two sides; implementing back-filling with a planting soil layer; installing rainwater grates and well coves and implementing construction of a gravel block belt; planting plants; and implementing cleaning as well as acceptance and inspection. According to the construction method provided by the invention, a conventional drainage mode, adopted by urban roads, of direct discharging at a source and centralizing at an end, is changed, and a problem on drainage is solved; meanwhile, by planting the rainwater-cultivated plants in the bioretention trough in normal times, rainwater is utilized; and a urban heat island effect is solved and effects of lighting urban and beautifying environment are achieved.

Description

technical field [0001] The invention relates to the technical field of rainwater treatment, in particular to a construction method for a LID biological retention ditch in an urban road green belt. Background technique [0002] With the vigorous development of cities, urban development is facing huge environmental and resource pressures. At the same time of urban development and construction, the ecological ontology has been destroyed to a certain extent, the hydrological laws have been disrupted, and water ecological damage, water safety risks, Water environment pollution and water shortage and other problems, so the concept of "sponge city" construction came into being. [0003] However, the traditional urban belt road green belt bioretention ditch is accustomed to the urban construction mode of overcoming and transforming nature, with "quick elimination" and "end-centralized" control as the main planning and construction concepts, resulting in serious urban diseases and ec...
