Problems solved by technology

[0003] When the oil and gas pipeline is fixed and supported by means of "U"-shaped pipe clips, the structure is simple, but it has the following disadvantages: (1) It is necessary to set concrete buttresses and pre-embedded anchor bolts at certain intervals on the tunnel floor, It increases the difficulty of installing oil and gas pipelines in the tunnel, and the installation and construction of the pipelines are very difficult; (2) It is difficult to align and position the anchor bolts for fixing the "U"-shaped pipe clips and the reserved holes of the pipe clips. It is very difficult to install pipe clamps; (3) "U" type pipe clamps can only fix oil and gas pipelines, but cannot play the role of supporting pipelines. The pipelines must be supported by concrete piers

specific Embodiment approach

[0020] A specific embodiment of the present invention is: a saddle support for fixing an oil and gas pipeline in an underwater tunnel, which includes a pipe clip 1 and a pipe clip 2 with a semicircular cross section. Pipe clips 1 and 2 are semicircular steel plates, a straight section extends from both ends of the steel plate, and ear-shaped ribs 4 are welded on the outer side of the steel plate, and holes are reserved on the exposed straight end surface for Install bolts and nuts 8. Bolts and nuts 8 connect and fix the upper and lower semicircular pipe clamps 1 and 2 together through the reserved holes, and at the same time play the role of fixing and supporting the oil and gas pipeline 9 .

[0021] Obviously, in practical implementation, the upper semicircular tube clamp 1 of the present invention is an integrated structure, while the lower semicircular tube clamp 2 and the saddle rib 5, trapezoidal rib 6, trapezoidal rib 7 and rectangular base 3 Both are one-piece structur...

Abstract

The invention provides a saddle support for fixing petroleum and natural gas pipelines in an underwater tunnel, and belongs to the technical field of fixing and anchoring the petroleum and natural gas pipelines in the underwater tunnel. The saddle support is composed of an upper semicircular pipe clamp, a lower semicircular pipe clamp and a rectangular base plate. Straight sections are arranged at the exposed end portions of the upper and lower semicircular pipe clamps, ear-shaped rib plates are connected to the outer side surfaces of the end portions of the straight sections, the lower semicircular pipe clamp is welded with a saddle rib plate and a trapezoidal rib plate, and the rectangular base plate is welded with the saddle rib plate and the trapezoidal rib plate. A bolt hole is reserved on the base plate. The saddle support is capable of improving the rigidity of the pipe clamps and has the characteristic of fixing and supporting the pipelines; besides, the saddle support is easy to process and fabricate, convenient to mount on the spot in the tunnel and relatively low in cost. The saddle support is mainly used for fixing and support the petroleum and natural gas pipelines in the underwater tunnel.

Description

technical field [0001] The invention relates to the technical field of fixing and anchoring of oil and gas pipelines in underwater tunnels. Background technique [0002] When laying oil and gas pipelines in long-distance oil and gas pipelines through deep tunnels through rivers and other waters, in order to reduce the variable temperature stress and deformation of oil and gas pipelines caused by temperature changes inside and outside the tunnel, and to prevent the tunnel from being filled with water Afterwards, the oil and gas pipeline will float up under the action of water buoyancy, and to ensure the stability and safety of the pipeline in the tunnel, the pipeline needs to be fixed and supported. The usual practice is to set a pipeline concrete support pier at a certain distance on the tunnel floor, place the oil and gas pipeline on the support pier, and use "U"-shaped pipe clamps to fix the pipeline on the concrete support pier, "U" "Type pipe clips and concrete pier are...
