Problems solved by technology
[0004] The present invention aims to solve the above-mentioned problems existing in the construction of the existing pipe gallery, and provides a construction method for pipe gallery piercing, so as to realize the cutting and segmentation of the pipeline as little as possible, and relatively fixed locations. The purpose of transporting long pipelines directly to the pipeline gallery

Embodiment Construction
[0020] The present invention is described in detail below in conjunction with the examples, and the purpose is only to better understand the content of the present invention.
[0021] A pipe tunnel construction method for a pipe gallery, which is carried out according to the following steps:
[0022] (1) see figure 1 , firstly select one end of the straight section of the pipe gallery as the entrance of the pipe 3 into the pipe gallery. Make use of the pipe gallery support 1 as much as possible. Two welding machines, 2 welding personnel and 2 piping personnel can be installed on the welding platform to carry out pipeline welding.
[0023] (2) see figure 2 , install a traction device at the outlet end of the pipe gallery.
[0024] Principles for selecting the exit end of the pipe gallery:
[0025] If the length of the straight section of the pipe profile is longer than the maximum traction distance of the tractor 6, the outlet end is set according to the maximum traction ...

The invention relates to a pipe gallery pipe penetrating construction method, in particular to a pipe gallery pipe penetrating construction method for an underground or a ground pipe gallery. The method comprises the steps as follows: firstly, a welding platform for carrying out pipeline welding is erected at an inlet; secondly, a pulling device provided with a pulling cart is mounted at the outlet end of the pipe gallery; the pulling cart draws out a steel wire rope for being connected with a pipeline. Through adopting corresponding devices for pulling the pipeline to penetrate into the pipe gallery, enabling a follow-up pipeline to be welded with the front pipeline continuously into a whole in a pulling process, and performing the welding operation on the relatively fixed platform, the welding speed and welding quality are improved, the problems of large labor intensity and high welding difficulty during manual pipe penetrating are overcome, the cutting times for the pipeline are reduced in large amount, the welding length of the pipeline is reduced correspondingly, and the material as well as the labor are saved.
Description
technical field [0001] The invention relates to a pipeline construction method, in particular to a pipeline penetration construction method in an underground or above-ground pipe gallery. Background technique [0002] At present, whether it is an existing or newly-built pipe gallery, when considering the economy, in order to make full use of the space, arrange as many pipelines as possible, basically seldom consider the construction requirements; Sometimes it is continuous, and others are basically discontinuous, consisting of pipe supports with different intervals, ranging from 6-9m. [0003] During construction, the pipe is usually cut into pipe sections slightly smaller than the interval according to the distance between the pipe supports, and the pipe sections are transported to the vicinity of the pipe supports in order. The transportation on the ground can be carried out by means of transport vehicles or manpower, and most of the underground pipe galleries use manpower...
