Trenchless pipe playing-free method for underground pipeline construction

Abstract

The invention discloses a trenchless pipe playing-free method for underground pipeline construction. The method comprises the following steps of adopting trenchless technology to excavate pipeline passages, filling pipe wall reinforcement materials into the pipeline passages, adopting a pipe expansion method to pressurize the pipe wall reinforcement materials to form pipeline walls, and filling the pipeline passages with high-temperature hot steam to maintain the pipeline walls. The trenchless pipe playing-free method for underground pipeline construction, by using trenchless technology for excavation, will not hinder traffic, not destroy green space and vegetation, and not affect the shops, hospitals, schools and the normal life and work order of the residents, and solves the interferenceof the residents' lives due to the traditional excavation construction, and the damage and adverse effects on the traffic, the environment and the surrounding building foundations. The method of filling the pipe wall reinforcement materials into the pipeline passages, adopting the pipe expansion method to pressurize the pipe wall reinforcement materials to form pipeline walls, and filling the pipeline passages with high-temperature hot steam to maintain the pipeline walls can be used to realize free pipe-laying. The integral molding method is used to form pipe walls of the pipelines, which greatly reduces the difficulty of construction and construction period.

Description

technical field [0001] The invention relates to the technical field of pipeline construction, in particular to a non-excavation underground pipeline construction free of pipe laying method. Background technique [0002] Most of the current underground pipeline construction methods are to lay pipelines after large-scale excavation. This method will affect the daily life of residents and cause certain damage to buildings and the environment. [0003] If the non-excavation method is used for construction, the construction difficulty and construction period will be greatly increased. Contents of the invention [0004] In view of the problems existing in the prior art, the present invention discloses a non-excavation underground pipeline construction avoiding pipe-laying method. The adopted technical solution includes excavating the pipeline channel by adopting the non-excavation technology, and filling the pipeline wall into the pipeline channel. Reinforcement materials, usin...
