Concrete structure of in-situ protective large-diameter oil-gas pipeline and construction method

Abstract

The invention discloses a concrete structure of an in-situ protective large-diameter oil-gas pipeline and a construction method. The construction method specifically comprises the steps of pipeline position exploration and excavation, accompanying optical cable relocation and transformation, steel sheet pile protection, protection culvert construction, alternating current interference protection construction and reinforcement of foundations on the two sides of a protection culvert. According to the concrete structure of the in-situ protective large-diameter oil-gas pipeline, large-diameter oil-gas pipeline relocation and transformation are avoided during roadbed construction, the influence of construction on pipeline operation is reduced, the pipeline operation safety during construction is ensured, the influence of highway and railway operation on the pipeline is solved, later maintenance is facilitated, a large settlement difference between the roadbed and the protection culvert can be avoided, the stability of the roadbed is ensured, and the project progress is accelerated; and under the regulation and control of the national coal-to-gas energy policy, the in-situ protective oil-gas pipeline is adopted, so that it is ensured that a valve is not closed, pressure is not reduced, and conveying is not stopped, and the concrete structure plays a very important role in relieving national energy supply shortage and promoting environmental governance.

Description

technical field [0001] The present invention relates to the field of pipeline protection construction, in particular to a concrete structure and construction method for in-situ protection of large-diameter oil and gas pipelines, which are mainly used in roadbeds spanning large-diameter oil and gas pipelines, where large safety risks and large social resources are consumed due to relocation , take in-situ gas protection. Background technique [0002] With the rapid development of my country's highway and railway networks, it is inevitable to intersect with various oil and gas pipelines and carry out a large number of pipeline relocations. The relocation is not only time-consuming but also expensive. A large amount of resources will be invested in the gas stop and relocation, which consumes a lot of resources. Large, correspondingly the entire construction period will be greatly affected. How to avoid pipeline relocation during subgrade construction, and solve the impact on pi...

[0002] With the rapid development of my country's highway and railway networks, it is inevitable to intersect with various oil and gas pipelines and carry out a large number of pipeline relocations. The relocation is not only time-consuming but also expensive. A large amount of resources will be invested in the gas stop and relocation, which consumes a lot of resources. large, correspondingly the entire construction period will be greatly affected

How to avoid pipeline relocation during subgrade construction, and solve the impact on pipelines during road and railway operation, whether there is a reasonable and feasible plan, will seriously restrict the progress of road and railway construction
