Embodiment Construction

[0040] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0041] refer to figure 1 , figure 2 , is an anti-floating structure for pipelines disclosed in the present invention, which includes a pipeline installation ditch 1 on the ground, and a number of concrete pads are sequentially laid on the bottom surface of the pipeline installation ditch 1 along the length direction of the pipeline installation ditch 1 The top surfaces of the slab 2 and the concrete pad 2 are all located on the same horizontal plane.

[0042] A prefabricated pipeline 3 is arranged inside the pipeline installation ditch 1 , and the prefabricated pipeline 3 is laid on the top surface of the concrete pad 2 . The prefabricated pipeline 3 is formed by connecting several pipe joints 31 end to end. The quantity of the prefabricated pipes 3 corresponds to the quantity of the concrete backing plates 2 and is arranged one by one relative to each ot...

Abstract

The invention relates to an anti-floating structure of a pipeline. The anti-floating structure comprises a pipeline installation ditch, a prefabricated pipeline is arranged in the pipeline installation ditch, a cross beam is arranged at a ditch opening of the pipeline installation ditch, the two ends of the cross beam are respectively fixed with the ground on the two sides of the pipeline installation ditch, a vertically-arranged pressing rod is arranged on the cross beam, and the pressing rod can move downwards so as to apply downward pressure to a pipe joint so as to press and fix the prefabricated pipeline. The anti-floating structure has the advantages that the pipeline is limited, so that the pipeline is not likely to move and float in position in the backfilling tamping process. Theinvention also discloses a construction method of the pipeline. The construction method has the advantages that when the pipeline installation ditch is backfilled, the pressing rod applies downward pressure to the prefabricated pipeline so as to press and fix the prefabricated pipeline into the pipeline installation ditch, the movement and floating phenomena of the position of the prefabricated pipeline are not likely to occur in the process of backfilling the pipeline installation ditch, and the construction quality of the prefabricated pipeline is guaranteed.

Description

technical field [0001] The invention relates to the technical field of pipeline construction, in particular to a pipeline anti-floating structure and a pipeline 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 the pipeline is in a free state when it is buried, and the backfill compaction strength is uneven during the backfill process, resulting in displacement of the pipeline, or the water-tight compaction method is used for medium-coarse sand backfill compaction, resulting in floating pipes. . This situation i...
