Installation method of truss pipeline penetrating through highway culvert

Abstract

The invention relates to an installation method of a truss pipeline penetrating through a highway culvert. The installation method comprises the following steps that sites at the two ends of the axisof the pipeline are leveled; a winch is arranged on the axis of the pipeline; a truss is arranged in the culvert; the length of the pipe sections of the pipeline is controlled, so that the length of each pipe section is larger than the distance between any two horizontal supporting beams; a prefabricated bracket with rollers is placed on the horizontal supporting beams; the pipe sections are dragged and pulled in place through the winch; all the pipe sections are sequentially pulled in place according to the steps, and the adjacent pipe sections are welded to form an integral pipeline; after the pipeline is installed, the bracket is taken out, and fixed supports of the pipeline are welded; and the height of a stand column at the other side is increased, and a top beam is arranged at the tops of the stand columns. The installation method of the truss pipeline penetrating through the highway culvert can realize the installation of the truss pipeline into a highway culvert site which is complex in underground structure and inconvenient in transportation and cannot be entered by a crane, avoids the damage to a highway and an original culvert structure, reduces the installation difficulty of the truss pipeline into the highway culvert, and shortens the construction period.

Description

technical field [0001] The invention belongs to the technical field of installation of truss pipes, in particular to a method for installing truss pipes running through high-speed culverts. Background technique [0002] For the installation of pipelines that need to run through high-speed culverts, the buried pipeline installation method can be used. This installation method has the disadvantages of large construction volume and long construction period, especially for construction sites with complex underground structures. safety and quality hazards. However, in the prior art, when using trusses to install pipelines, a crane needs to be used for hoisting, and for construction sites where traffic is inconvenient and cranes cannot enter, the traditional truss pipeline installation method cannot be applied. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for installing truss pipes running through high-spe...
