Fixing device for preventing sedimentation stretching of straight-buried pipe

Abstract

The invention discloses a fixing device for preventing sedimentation stretching of a straight-buried pipe. The fixing device comprises a pull rod, a pipe fixing component and a structure fixing component, wherein the pipe fixing component comprises a fixed sleeve, an arc fixed plate and two pipe hinge plates; the structure fixing component comprises a fixed baseplate and two structure hinge plates; the two ends of the pull rod are respectively connected with hinge plates; the hinge plate at one end of the pull rod is hinged with the two pipe hinge plates; the hinge plate at the other end of the pull rod is hinged with the two structure hinge plates; the structure fixing component is fixed in strength points of such different buildings as a structural bearing platform and a ground beam; the pipe fixing component is fixed on the straight-buried pipe; as the two ends of the pull rod are hinged with the pipe fixing component and the structure fixing component, when the straight-buried pipe is stretched, the straight-buried pipe can be synchronously and uniformly stretched to the left and right sides from the middle, and the stretching stress of the straight-buried pipe is effectively dispersed; and when the straight-buried pipe is sedimentated, the pull rod can effectively unload to prevent the tensile failure.

Description

technical field [0001] The invention relates to the technical field of pipeline construction engineering, in particular to a fixing device for preventing the settlement and stretching of directly buried pipelines. Background technique [0002] In cold and hot water direct-buried pipe projects, direct-buried pipes will stretch due to temperature differences. If there is a lack of necessary anti-stretch measures, pipeline deformation, necking, cracking and leakage will often occur. After the above problems occur in the pipeline, The difficulty and impact of restoration are very large. [0003] The traditional direct-buried pipeline project mainly adopts anti-stretch measures in the horizontal direction to solve the above problems. However, in subsidence areas, direct-buried pipelines are prone to vertical stretching due to settlement, and the tensile force during settlement is very large. If there is no vertical Tensile resistance measures in the direction, the pipeline is p...

However, in subsidence areas, direct-buried pipelines are prone to vertical stretching due to settlement, and the tensile force during settlement is very large. If there is no vertical The anti-stretch measures in the direction, the pipeline is prone to cracking and leakage, causing huge losses
