Description

Technical Field

[0001] The utility model relates to the technical field of pipeline construction, in particular to a non-disturbance high-pressure oil and gas pipeline protection construction device. Background Art

[0002] Buried pipelines are an important infrastructure in modern society. Due to their concealed nature, buried pipelines are difficult to detect and repair. Once an operation accident occurs, in addition to the direct losses caused by damage to the pipeline system itself, serious secondary disasters may also occur, causing huge economic losses and even casualties, threatening social production and life safety.

[0003] At the same time, my country's road traffic is developing rapidly. The large-scale construction of highways and railways will inevitably intersect or run parallel with existing buried pipelines. The measures generally taken are to cross the pipelines in the form of bridges and protect the pipelines in the form of culverts.

[0004] The general construction method of the protective culvert is: after finding out the location of the pipeline and the optical cable, the earth and stone near the pipeline are removed by manual excavation, and the pipeline is subjected to a series of treatments such as flaw detection and anti-corrosion, and then the foundation and wall of the protective culvert are constructed, and then the earth and stone near the pipeline are backfilled, and finally the culvert cover is installed. This construction method not only has many processes and a long construction period, but also the pipeline is always exposed during the construction process, and it is necessary to protect the pipeline from rain and sun exposure. In addition, the construction of the protective culvert has a great impact on the pipeline. Various hoisting operations or foundation pit collapse will cause deformation or rupture of the pipeline, which has a high safety risk, strict and complex management requirements, a long construction period, and high cost investment.

[0007] The outer bottom of the steel sheet pile is cast to form a protective culvert foundation, the top of the protective culvert foundation is fixed with a protective culvert wall, and the top of the protective culvert wall is used to support and place a protective cover plate.

[0008] The steel sheet piles are driven into the foundation by a vibration-free hydraulic method.

[0009] The back rib assembly includes an outer back rib fixed on the outer wall of the top of the steel sheet pile, and an inner back rib fixed on the inner wall of the top of the steel sheet pile.

[0010] A supporting step is arranged on the top of the protective culvert wall, and the supporting step is used for positioning and installing the protective covering plate.
