Integrated pipe network and drainage system under for pavement

Abstract

An integrated pipe network and drainage system for a pavement. The system comprises water collecting wells, wherein the water collecting wells are arranged below sides of the pavement at intervals, water-permeable cover plates A are arranged at water collecting ports at upper ends of the water collecting wells, the adjacent water collecting wells communicate with each other through a rainwater pipeline; and the rainwater pipelines communicate with a water drainage terminal; water outlets A are formed in side walls of the water collecting wells. The system further comprises U-shaped ditches, hollowed-out bottom plates and cushion layers, each U-shaped ditch comprises a left wall, a right wall and a connection plate connected to the lower end of the left wall and the lower end of the right wall, drainage holes are formed in each connection plate at intervals, the hollowed-out bottom plates are road surfaces of the pavement and mounted at the upper ends of the U-shaped ditches, and an overhead cavity is formed between each hollowed-out bottom plate and the corresponding U-shaped ditch; the cushion layers are arranged at lower ends of the U-shaped ditches; water inlets A of the U-shaped ditches communicate with the water outlets of the water collecting wells through pipelines. The system has the advantages as follows: establishment of an ecological city is facilitated, the municipal integrated pipe network can be accommodated, urban inland inundation is prevented, and formation of lakes on a road is prevented.

Description

technical field [0001] The invention relates to an urban drainage pipe network system, in particular to a sidewalk comprehensive pipe network and a drainage system. Background technique [0002] Many cities in our country will experience waterlogging when they encounter heavy rainfall. In addition to the high frequency of extremely bad weather, there are also problems in urban construction itself. A large number of hard pavements, such as asphalt roads and cement pavements, have poor permeability when it rains, are not easy to infiltrate, and easily form water accumulation on the road surface. The urban comprehensive pipe network system that does not match the speed of urban development is the most important factor that causes waterlogging. [0003] Therefore, there are two main factors causing the current urban waterlogging problem: one is the deficiency of the existing urban comprehensive drainage pipe network system, and the other is that the urban road surface has poor ...

AI Technical Summary

Problems solved by technology

It solves the problems of high cost of reconstruction and expansion of the urban comprehensive pipeline network, poor drainage capacity, and difficult maintenance in the later stage, and improves the safety performance of the urban comprehensive pipeline network and reduces the difficulty of construction. It also provides convenience for the later maintenance of the comprehensive pipeline network condition
