Construction method of self-priming municipal drainage system

Abstract

The invention belongs to the technical field of municipal drainage, and particularly relates to a construction method of a self-priming municipal drainage system. The construction method comprises thefollowing steps of S1, excavating a strip-shaped foundation pit in the width direction of a road; S2, installing a kinetic energy recovery device in the foundation pit; S3, constructing installationpositions of energy storage equipment and a suction device on the two sides of the road; S4, installing the energy storage equipment and the suction device, connecting the energy storage equipment andthe suction device, communicating one end of the suction device into inspection wells on the two sides of a low-lying road surface, and communicating the other end of the suction device with an urbandrainage network; S5, connecting the kinetic energy recovery device with the energy storage device; and S6, laying speed bumps on the kinetic energy recovery device. By means of the construction method, no external connection of energy supply equipment is needed; the construction method is a simple and efficient road surface drainage solution; and meanwhile, the braking force of vehicles can be recovered and utilized, and the construction method has great environmental protection significance.

Description

technical field [0001] The invention belongs to the technical field of municipal drainage, and in particular relates to a construction method of a self-priming municipal drainage system. Background technique [0002] With the continuous expansion of the city, more and more intersections have begun to build three-dimensional traffic facilities such as elevated roads and underpasses to improve road traffic efficiency. With the reconstruction of these roads, the urban drainage system must also be upgraded accordingly. However, it was often difficult to predict the future urban construction development trend when the early urban drainage network was constructed, so it was generally set at a shallower position from the ground when it was constructed, which has led to the fact that most of the underpass road sections today are lower than The height of the original urban drainage network, so if the drainage system of the underpass road section is connected to the original urban dra...

Problems solved by technology

However, it was often difficult to predict the future urban construction development trend when the early urban drainage network was constructed, so it was generally set at a shallower position from the ground when it was constructed, which has led to the fact that most of the underpass road sections today are lower than The height of the original urban drainage network, so if the drainage system of the underpass road section is connected to the original urban drainage network, water conservancy facilities such as pumping stations must be installed on these road sections

Existing pumping stations are mainly driven by electric energy, which not only has high construction costs, but also generates huge energy consumption. When encountering heavy rain, the efficiency of upgrading is often insufficient, which can easily lead to water accumulation on the road, resulting in huge loss of personnel and property
