Problems solved by technology

Generally speaking, the sewage system equipped with such equipment generally uses slurry pumps, submersible pumps or diaphragm pumps for sewage discharge. The service life of various types of pumps is greatly reduced, and a certain number and different types of wearing parts need to be equipped on site, and the process of replacing wearing parts on site takes a lot of time, which will have varying degrees of impact on equipment management and on-site efficient construction , which affects the construction efficiency and construction cost to a certain extent

Abstract

The invention relates to the technical field of engineering construction, in particular to a tunnel vacuum sewage discharge system and a sewage discharge method. The system comprises a suction mechanism and a sewage discharge mechanism, the sewage discharge mechanism comprises a sewage discharge tank and a pressure regulating pipeline, a vacuum port is formed in a sewage tank, and a sewage inlet and a sewage discharge port are formed in the bottom of the sewage discharge tank; the suction mechanism comprises a sewage filtering device disposed at a water accumulated position of a tunnel and a vacuum pump connected to the vacuum port through the vacuum pipeline, the sewage filtering device is communicated with the sewage inlet through a sewage treatment pipeline, a vacuum regulating valve isarranged on the vacuum pipeline, and a sewage control valve is arranged on the sewage treatment pipeline; the sewage discharge port is connected to a muck transport vehicle or an external sewage discharge pipeline through the sewage discharge pipeline, and the sewage discharge pipeline is provided with the sewage discharge valve. The system has novel and reasonable design and strong sewage absorption ability, automatically discharges sewage under the participation of a control system, reduces the loss of consumable parts, achieves rapid sewage discharge, and improves construction efficiency.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to a tunnel vacuum sewage discharge system and a sewage discharge method, which can be applied to sewage discharge in the construction of trenchless equipment such as tunnels and comprehensive pipe galleries. Background technique [0002] In traditional tunnel construction, the road surface is re-excavated or the mining method is used for construction, and the sewage can be directly exported with the excavated medium. With the advancement of smart cities, the application of a series of large-scale non-excavation equipment such as shield tunneling and pipe jacking has become normalized in the construction of tunnels and comprehensive utility corridors. In the construction of large-scale trenchless equipment, due to the washing of the equipment or the partial seepage of the ground, after the equipment has been in operation for a period of time, it is necessary to disc...
