Wetland paving method and recycling method

Abstract

The invention relates to the field of oil and gas pipelines, discloses a wetland paving method and a recycling method and solves the technical problem of either high cost or long time during paving of a construction operation zone in the prior art. The method comprises the steps of transporting a wetland paving device to the construction site through a transport vehicle; starting a hydraulic motor after the transport vehicle enters the operation plane of the construction site; rotating a barrel support motor to drive a barrel support to rotate by 90 degrees towards the first direction; arranging a metal road surface on an upper guide wheel set through a barrel; starting the hydraulic cylinder to push a beam support to extend outwards after the extended length of the metal road surface on a beam exceeds the preset length through rotating the barrel, to control the metal road surface to fall onto a lower guide wheel set; rotating the barrel to cause the metal road surface to fall to the ground; and after the metal road surface falls to the ground, and controlling the transport vehicle to back off and controlling the barrel to go on rotating. By applying the wetland paving method and the recycling method, the technical effects of both decreasing the time and lowering the cost during paving of the construction operation zone are achieved.

Description

technical field [0001] The invention relates to the field of pipeline engineering, in particular to a wetland paving method and a recovery method. Background technique [0002] When laying long-distance oil and gas pipelines in swampy areas with high groundwater levels, due to poor surface bearing capacity, various methods are generally used to pre-harden the surface before construction or adopt technical measures such as laying steel floating slabs and transportation tracks. In order to facilitate the passage of steel pipe transportation, construction and welding equipment in the construction work zone. [0003] When oil and gas pipelines are constructed in water network swamp areas with high groundwater levels and poor surface bearing capacity, various methods are generally used to pre-treat the construction work zone to increase the hardness of the surface and increase the bearing capacity. One of the main methods is to build a dam at the boundary of the working zone whe...

AI Technical Summary

Problems solved by technology

These three methods are relatively typical construction methods in water network swamp areas. The first method is relatively simple but the construction period is long, especially in the rainy season in the south. decrease, cost increase

The second method is generally only suitable when the construction site permits. The amount of sand and gravel in the laying operation belt is large, and the cost of procurement and transportation is high. At the same time, in order to restore the landform, the cost of sand and gravel removal is also increased.

The third method of laying steel floating boards or sleeper rows requires the production of a large number of steel floating boards and sleeper rows, which are heavy in weight and high in production costs. Special equipment is also required for reverse transportation at the construction site, and the transportation cost for transfer is high.

[0004] That is to say, in the prior art, there are technical problems of high cost or long time when laying the working belt.
