Pipeline anti-displacement anti-floating mechanism and pipeline anti-floating construction method

Abstract

The invention provides a pipeline anti-displacement anti-floating mechanism and a pipeline anti-floating construction method, and belongs to the field of buildings. The mechanism comprises a cross rod, at least one group of diagonal bracing assembly and at least two groups of limiting components, wherein the cross rod is arranged above the pipeline in parallel, the diagonal bracing assemblies comprise diagonal bracing pipelines and positioning structures, the positioning structures comprises flat steel, a plurality of clamping sheets and friction pads, one ends of the diagonal bracing pipelines are hinged to the transverse rod, the other ends of the diagonal bracing pipelines are connected to the flat steel, one ends of the plurality of clamping sheets are connected to the flat steel, theother ends of the plurality of clamping sheets are connected to the friction pads, a plurality of protrusions are mounted on the friction pads and are movably abut against the inner side walls of a foundation pit, the two groups of limiting components are movably arranged at the bottom of the cross rod and are positioned on two opposite sides of the pipeline, and one ends of the two groups of limiting components are abutted against two opposite inner side walls of the foundation pit correspondingly. The mechanism has the advantages of being reasonable in structure, light, economical and practical, capable of being repeatedly used and suitable for two working conditions of foundation pit vertical excavation and unprotected open cut excavation.

Description

technical field [0001] The present application relates to the field of construction, in particular to a pipeline anti-displacement and anti-floating mechanism and a pipeline anti-floating construction method. Background technique [0002] With the steady growth of the country's economy and the vigorous development of infrastructure construction, the construction quality of hidden projects for pipeline burial has been paid more and more attention. However, in practice, the construction quality is often not well controlled, and displacement, alignment irregularities, joint arching, and Common quality problems such as reverse slope seriously affect the function of the pipeline. The main reason is that there are no fixed measures in the process of backfilling on both sides and top of the pipeline, and the backfill compaction strength is uneven, resulting in displacement of the pipeline, or the medium-coarse sand backfill is compacted by water-tight compaction, resulting in float...
