Rail type in-situ purification method for drainage pipeline

Abstract

The invention provides a rail type in-situ purification method for a drainage pipeline. A chain type rail is mounted in an inspection well and the drainage pipeline, suspended supports are suspended on the chain type rail, treatment units are embedded into the suspended supports, driving chain wheels are driven by motors to rotate, then a chain is driven, thus, the suspended supports are conveyedinto the drainage pipeline, and an auxiliary unit is arranged on the ground outside the inspection well and used for assisting the treatment units in in-situ purification of the drainage pipeline. Theinternal space of the inspection well and the drainage pipeline is fully utilized, through ingenious design of the chain type rail and the suspended supports, the treatment units are conveyed and arranged in the drainage pipeline, and through the flexible combination of the treatment units and the auxiliary unit, in-situ water quality purification, disinfection and sterilization and dredging of the drainage pipeline are achieved. Compared with the prior art, the rail type in-situ purification method has the prominent characteristics of being high in applicability, easy to implement, diverse in function, flexible in operation, remarkable in effect and the like.

Description

technical field

[0001] The invention belongs to the technical field of municipal drainage, and in particular relates to an orbital in-situ purification method for drainage pipes. Background technique

[0002] Drainage pipes are engineering facilities that collect and transport urban domestic sewage, industrial wastewater and rainwater. In recent years, with the acceleration of my country's urbanization process, the number and scale of construction of drainage pipes are also increasing year by year. For example, during the "Thirteenth Five-Year Plan" period, on the basis of the total length of about 9,530 km of drainage pipelines in Shanghai, about 100 kilometers of supporting drainage pipelines were built in the central urban area, and about 310 kilometers of new drainage pipelines were newly built in the suburbs. The increasingly perfect drainage pipeline system provides convenience for the transportation of various types of sewage and rainwater in cities and towns. Howeve...
