Description

Pipeline trolley for pipeline penetration

Technical Field

The utility model relates to the technical field of pipeline engineering construction, in particular to a pipeline trolley for pipeline penetration.

Background

At present, in the construction of urban underground pipelines, various pipelines are compactly arranged for saving land resources, such as water supply, rainwater, sewage, gas, oil pipelines and the like which are generally laid in parallel. When the pipelines pass through roads or railways, in order to reduce the influence on the operation of the roads or railways, the pipelines are generally passed through in a pipe jacking mode. For example, in the engineering construction of pipeline crossing railway, a pipe jacking working well and a pipe jacking receiving well are arranged on two sides of a railway crossing position, 1 casing pipe is jacked to a certain depth below a railway subgrade by using a jacking machine and crosses the railway, and then a pipeline to be passed is installed in the casing pipe in the pipe jacking working well.

In many cases, pipelines to be passed for different purposes are built by different units, communication connection is lacked among the building units, and it is rarely considered that a plurality of pipelines share one pipe jacking project for passing through, so that when the pipelines pass through a railway, generally 1 pipeline is passed through by the pipe jacking independently, and only 1 pipeline is arranged in a sleeve of the pipe jacking project. Because the pipe jacking deep foundation pit and the sleeve pipe related to the pipe jacking project are jacked and constructed under the road, the construction cost for penetrating through the project by each pipe jacking is high, and the investment of 1 pipe jacking is usually as high as millions of yuan. If a plurality of through pipelines share one pipe-jacking project to cross a road on site, most of the pipelines are jacked into a roadbed downwards in a shared pipe-jacking working well, and the pipelines respectively penetrate through the pipelines in the casings.

In traditional construction methods, 1 pipeline is worn in 1 sleeve pipe that passes through, and pipeline platform truck is all installed to the intraductal pipeline of common sleeve, but most of the time these traditional platform trucks all take the ring carrier form, and a plurality of gyro wheels of a week installation on the ring carrier roll through the gyro wheel, push the pipeline into the sleeve pipe. The crossing mode of the pipeline in the sleeve can cause the pipeline to be twisted in the sleeve frequently, so that the anticorrosive coating of the pipeline is damaged. Sometimes, the pipeline is excessively distorted and deformed, so that stress concentration occurs in a pipe body mountain, and the safety of the pipeline is influenced.

According to the traditional pipeline crossing mode, each pipeline crosses independently, sleeves are arranged at crossing positions respectively, and site conditions which can meet the crossing of a plurality of pipelines are difficult to find on site. If several pipes are considered to share one casing for crossing, according to the conventional casing-in-pipe crossing manner, if the length of the crossed casing is large, for example, more than 100m, it is almost impossible to cross several pipes in 1 casing. The penetration mode also easily causes the damage of the anti-corrosion layer of the pipeline, and the safety of the pipeline is influenced. Even if the push pipe working well is shared, a plurality of sleeves need to be jacked respectively, jacking cost is large, jacking distance between the sleeves needs to be increased for avoiding mutual safety influence, and the size of a push pipe foundation pit is increased, so that engineering investment is further increased.

In addition, when the pipeline passes through the road surfaces such as the railway, certain influence is generated on the railway operation, and railway administrative departments generally require that the pipeline does not pass through the same area for many times.

Therefore, those skilled in the art have endeavored to provide a pipeline trolley for pipeline penetration, which can realize rapid pipeline penetration, reduce cost and shorten construction period.
