Embodiment Construction

[0033] Such as figure 1 As shown, the buried large-diameter flexible pipeline of the present invention includes a circular pipe body 1, a bottomless triangular beam 2 positioned at the top of the pipe body, anchor rods 3 connected around the pipe body, a base 4 at the bottom of the pipe body and two End ferrule 5. The pipe body 1 is the main part of the pipeline, which adopts a circular thin-walled structure with a large diameter, and mainly undertakes the transportation function of the pipeline. The pipeline is made of metal or chemical pipes and belongs to flexible pipelines. The bottomless triangular beam 2 at the top of the pipe body is clamped between the hoops 5 at both ends, the thickness is the same as that of the pipe body, and the bottomless triangle has a vertex angle of 60°. The bottomless triangular beam 2 at the top of the pipe body and the base 4 at the bottom of the pipe body are connected with the pipe body 1 and the ferrule 5 as a whole by selecting welding...

Abstract

The invention discloses a buried large-diameter flexible pipe for controlling settlement and a processing method thereof. The anchor rod and the base at the bottom of the pipe body; there are anchor rod holes around the pipe body, and the anchor rod is fixed around the pipe body through the anchor rod holes. The anchor rod includes a cylindrical straight rod, a nut, a gasket, and a spiral support on the straight rod. The disc and the tapered anchor head at the end, the anchor rod is fixed to the pipe body through nuts and gaskets; the bottomless triangular beam is clamped between the ferrules at both ends, and the base and the pipe body are connected as a whole. The bottomless triangular beam of the present invention enhances the rigidity of the top of the pipe, and limits the downward sag of the top of the flexible pipe under the action of external load; the anchor rod restricts the circumferential deformation of the flexible pipe; the base supports the overall pipe body and strengthens the bottom of the pipe body Strength of. The invention solves the problem of pipeline deformation and damage caused by uneven settlement of pipelines in soft soil roadbed or local stress concentration.

Description

technical field [0001] The invention relates to underground pipelines in geotechnical and municipal engineering, in particular to an underground large-diameter flexible pipeline with controlled settlement and a processing method thereof. Background technique [0002] With the rapid economic development and the advancement of urbanization, buried pipelines have been widely used in the current society. As an effective means of material transportation, buried pipelines are widely used in the fields of municipal administration, water conservancy, transportation and energy, and play an important role in modern industry and agriculture and people's lives. Due to the needs of urban construction, municipal pipelines are directly buried under the road, and the loads directly or indirectly acting on the buried pipeline mainly include dead loads such as the dead weight of the pipeline structure, filling pressure, fluid gravity, traffic load, ground pile load, and temperature load. , p...
