Description

Device for preventing floating up during pouring of pipeline

Technical Field

The utility model belongs to the field of buildings, and particularly relates to a device for preventing floating up during pouring of a pipeline.

Background

When the MPP pipe pipeline calandria is arranged, the multi-layer calandria is carried out by combining the design drawing requirement and the field actual condition, and after the civil engineering pipe trench is excavated, construction operators carry out calandria. Most construction sites have pipeline floating conditions in construction. The construction method comprises the steps of pouring a layer of concrete, and pouring upper concrete after the concrete reaches a certain strength, wherein a floating phenomenon is generated in the concrete pouring process of the pipeline, so that a construction joint appears in the concrete pouring to influence the construction quality.

Disclosure of Invention

In order to solve the problems, the utility model discloses a device for preventing floating up during pouring of a pipeline, which is used for fixing an encapsulated pipeline in a bracket fixing mode to prevent floating up.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

prevent device of come-up when pipe casting, including installing a plurality of bases in the trench bottom, the base is pour along the pipeline direction of arranging, every pedestal mounting has the support, the support includes from the lower part connecting pipe, lower part support piece, middle part connecting pipe, middle part support piece, upper portion connecting pipe and upper portion support piece that upwards connect gradually earlier, lower part support piece middle part support piece with upper portion support piece's structure is the same, lower part support piece has bottom thread bush, holding ring and upper portion thread bush, bottom thread bush with lower part connecting pipe connection, the holding ring will bottom thread bush with upper portion thread bush is connected, upper portion thread bush with middle part connecting pipe connection.

Preferably, both sides of the supporting ring are provided with arc structures for matching with the outer contour of the encapsulated pipeline.

Preferably, two threaded rings are symmetrically welded on the outer side wall of the upper threaded sleeve, and each threaded ring is connected with a pipe pressing rod.

Compared with the prior art, the utility model has the beneficial effects that:

according to the utility model, the excavated pipe trench is utilized, the bracket is driven into the bottom of the pipe trench, the sealing pipeline is fixed in a bracket fixing mode, the floating is prevented, and meanwhile, the construction progress can be effectively improved; when the traditional concrete encapsulation pipeline is constructed, the pipeline is encapsulated by the concrete for half. And when the concrete reaches a certain strength, pouring the upper layer concrete. When the lower layer concrete is poured, the condition of floating up the pipeline still exists, and meanwhile, the construction joint exists, so that the progress is slow.
