Description

A moving device in buried casing

technical field

The utility model relates to an outer casing for buried pipelines, in particular to a moving device inside the buried casing.

Background technique

With the development of industry, various energy media are widely used. At present, the technology of laying non-overhead energy media pipelines that requires buried transportation is developing rapidly. Some mature excavation technologies are more suitable for gas buried pipelines and urban heat pipelines. Crossing underground obstacles, rivers, roads, buildings, etc., the pipe jacking technology used in trenchless pipeline laying is also relatively mature. In pipe jacking construction, the technology of installing multiple pipes in one casing is still somewhat unsatisfactory. For example, when the rare gas oxygen, nitrogen, and argon pipelines pass through underground obstacles, there is no good construction and installation method to use the same casing for protection. Some construction designers generally adopt some simple methods to insert the pipeline into the casing , the consequence is that the installation accuracy of the pipeline is not high, and pipeline quality accidents are prone to occur. The existing mobile support for the pipeline in the large-diameter casing has played a good role. However, there will be various changing factors in the construction conditions that will affect the construction progress and quality, such as the installation of multiple pipes in one casing, which needs to be constructed in stages, and cannot be constructed at the same time in one casing. For the overall installation conditions There are some construction technical difficulties, such as; the outer wall of the casing is anti-corrosion due to welding and heating, the input of a single pipe in the casing, the welding of the pipe, and the construction safety in the casing. Therefore, in order to solve these problems, it is necessary to design a casing suitable for buried pipelines, so that these casing components can be manufactured in the factory, avoid welding on the construction site so as to prevent corrosion of the outer wall of the casing, and reduce construction and installation costs. The device can be dismantled and reused after pipeline construction.

The protective material covering the outer surface of the roller;

Both ends of the first and second brackets are respectively fixed to the inner wall of the buried casing through a support seat.

Reinforcement protection plates are respectively provided between the support bases and the inner wall of the corresponding buried casing, and the support bases are fixed on the reinforcement protection plates; this can ensure that the pipe jacking construction process is not affected.

Beneficial effects of the utility model

According to the design requirements of multiple pipes, the utility model designs a horizontally placed co-rack bracket at the bottom of the casing, and the bracket can place pipes with different diameters; Staggered from each other, the purpose is that the pipeline installations will not be affected by each other.

The utility model is not limited by the harsh requirements of underground construction, and can also ensure the quality of construction and equipment, improve construction efficiency, reduce costs, and ensure safety. In order to reduce construction costs, the device can be removed after pipeline construction to achieve reuse.
