Pipe structure and its installation method for cross-rock section

Abstract

The invention relates to a cross-rock-section pipeline structure and an installation method for the same. The installation method is characterized in that a cross-rock-section pipeline aerial structure is used during pipeline erection at a cross-huge-rock section; anchor blocks are laid along a rock body at a certain interval; a pipeline transport track is used during installation of a cross-rock-section pipeline; transportation is conducted with a winch and an angle block; the pipeline is pieced on the rock body by a pipeline installation supporting frame; and at pipe-laying narrow sections during installation of the pipeline, a trapezoid groove steel frame, a bogie frame transport structure and a door-shaped lifting frame are used to ensure construction quality. The cross-rock-section pipeline and the installation method provided by the invention have the advantages that construction is convenient; use of large lifting equipment is omitted; obstacles brought by topographic conditionsare overcome; construction efficiency is increased; sliding and overturning of a fixed-shape angle iron support on the rock body can be prevented effectively; transport construction of the pipeline is safer; and technical problems in transport and piecing of the pipe-laying narrow sections can be solved effectively.

Description

technical field [0001] The invention relates to a rock-crossing pipeline structure and an installation method thereof, which belongs to the field of civil engineering and is particularly suitable for rock-crossing pipelines and installation construction. Background technique [0002] Water supply projects are important projects related to the national economy and people's livelihood, especially in remote mountainous areas with inconvenient transportation, and the construction of long-distance pipelines is an important infrastructure to meet this strategic demand. Due to my country's vast territory, plains, mountains, and water networks, the construction of pipelines must fully consider the influence of topography. When laying water replenishment pipelines in mountainous areas, due to the large undulations along the line, irregular exposure of rocks on the surface, steep slopes and long slopes, vertical and horizontal valleys, and rugged roads, it is not easy to build access ...

AI Technical Summary

Problems solved by technology

When laying water replenishment pipelines in mountainous areas, due to the large undulations along the line, irregular exposure of rocks on the surface, steep slopes and long slopes, vertical and horizontal valleys, and rugged roads, it is not easy to build access roads and operations for large-scale mechanical construction unlike construction in plain areas. belt, which brings great difficulties to pipeline installation, especially large-diameter pipeline installation

[0003] When erecting pipelines, we often encounter mountainous areas with complex terrain, which brings difficulties to pipeline construction, especially when there are steep slopes, rocks and other surfaces, and there are rocky cliffs on geological slopes, large machinery and equipment cannot enter, which causes greater difficulties for on-site pipe transportation.

[0004] In mountainous areas and other rock-crossing areas, the pipeline has to pass through high mountains, and the complex geology and climate have brought great difficulties to the construction
