Seepage storage tank for urban road and its construction method

Abstract

The invention discloses a water permeation and storage tank for an urban road, and belongs to the technical field of urban road water drainage and rainwater utilization. The water permeation and storage tank comprises a water permeation and storage tank body, wherein the side surface of the upper end of the water permeation and storage tank body is connected with a rainwater collection pipe; the bottom of the water permeation and storage tank body is closed; a water permeation and storage tank cover plate is arranged at the top of the water permeation and storage tank body; circular rainwater permeation holes with the diameters of 1 to 5 mm are uniformly formed in the whole water permeation and storage tank body; both the water permeation and storage tank cover plate and the water permeation and storage tank body are made of concrete materials. The invention further discloses a construction method of the water permeation and storage tank. Aiming at the existing urban road with a complete pavement and relatively high traffic flow, and an urban road section with a pavement not suitable for being transformed, the water permeation and storage tank enables rainwater to be gathered into the water permeation and storage tank through the collection pipe and to directly permeate into soil in a lateral zone and soil under border trees on a sidewalk; the rainwater is slowly released to irrigate plants; by the technology, the construction is facilitated, and the road is not needed to be closed; the cost of artificial irrigation is reduced, water resources are saved, and the soil can be irrigated more thoroughly; no artificial energy and no power input are needed in a whole system; the operation and maintenance cost is low, and the water permeation and storage tank is extremely high in practicability.

Description

technical field [0001] The invention belongs to the technical field of urban road drainage and rainwater utilization, and in particular relates to an infiltration water storage tank for urban roads and a construction method thereof. technical background [0002] In recent years, road waterlogging caused by heavy rainfall has been a chronic disease that affects pedestrian travel and even endangers urban traffic safety. It is common in Chinese cities. On the one hand, traditional asphalt or cement pavement surface drainage can only be carried out through storm water outlets, which is time-consuming It is long and prone to air resistance, and poor drainage leads to water on the road, which will not only cause vehicle tires to slip and become a safety hazard, but in areas with more water, it will seriously cause vehicles to be soaked in water and be scrapped, and pollutants will overflow to cause environmental pollution; On the one hand, there is a large demand for urban road gr...

Problems solved by technology

[0003] PE water storage devices are expensive, poor in strength and hardness, low in compression resistance, short in service life, and high in construction costs. They generally have a single water storage function, and geotextiles and permeable membranes are required to achieve water permeability. Use stored rainwater to infiltrate the soil for irrigation
