Pipe laying construction method and system inside sleeve pipe based on wheel-rail type pipe hoop

Abstract

The invention relates to a pipe laying construction method and system inside a sleeve pipe based on a wheel-rail type pipe hoop. The method comprises the following steps that the sleeve pipe is constructed; after constructing of the sleeve pipe is completed, a concrete cushion layer is constructed inside the sleeve pipe; after constructing of the concrete cushion layer is completed, sliding railsare symmetrically arranged on set positions of the two sides of the central axis of the concrete cushion layer; the two ends of a steel pipe are correspondingly and fixedly provided with pre-machinedpipe hoops with pulleys; and the steel pipe is lifted to an inlet of one end of the sleeve pipe so as to be laid, the pulleys of the pipe hoops are connected to the sliding rails on the concrete cushion layer in a sliding mode, the sliding rails are used for providing a fixed advancing route for the pipe hoops, and therefore the steel pipe penetrates into the sleeve pipe. According to the method,aiming at the problems that the advancing track of the pulleys of a traditional steel pulley bracket method is difficult to be unified, and the matching degree and the stability of the steel pipe on the bracket are poor, the pipe laying construction method inside the sleeve pipe based on the wheel-rail type pipe hoop is provided, the sliding rails are utilized for providing the fixed advancing route for the pulleys, and it is ensured that the advancing tracks of the pulleys for conveying all the steel pipes are kept consistent, the steel pipes are free of dislocation, and the directions of thesteel pipes are free of deviation.

Description

technical field [0001] The invention relates to the field of underground pipeline construction, in particular to a construction method and system for pipe laying in a casing based on a wheel-rail type pipe collar. Background technique [0002] With the development of the economy, the level of urban municipal facilities is getting higher and higher. In the construction process of underground water supply and drainage, gas, heat, electricity and other pipelines crossing urban roads, railways, rivers and other projects, in order not to affect other traffic and speed up the progress of the project , Reduce the impact on the surrounding environment, as the main trenchless construction technology, pipe jacking is being adopted more and more at home and abroad. According to the different uses of various pipelines, the completed pipe jacking is often used as casing and protective pipe, and pipelines for different purposes need to be inserted into it. In order to ensure the durabilit...
