Abstract

The invention relates to a pipeline bottom hollowing-out device and a construction method. The pipeline bottom hollowing-out device comprises a moving mechanism located at the bottom of a groove, a supporting plate connected to the upper part of the moving mechanism and an operation plate located above the supporting plate. A lifting mechanism for enabling the operation plate to ascend and descendis arranged between the supporting plate and the operation plate, a plurality of driving pieces and positioning assemblies are fixed to the operation plate, a plurality of jacking pipes are placed onthe positioning assemblies, the jacking pipes are inserted into soil through the driving pieces, and fixing assemblies for fixing the adjacent jacking pipes are arranged between the adjacent jackingpipes. The pipeline bottom hollowing-out device has the effect of improving the hollowing-out efficiency and safety.

Description

technical field [0001] The present application relates to the technical field of pipeline laying, in particular to a pipeline bottom hollowing out device and a construction method. Background technique [0002] When excavating trenches on roads and laying pipelines, there will be other pipelines such as electricity or communication across the road underground. Therefore, when digging trenches, the soil under the spanning pipelines needs to be hollowed out to Piping can be laid along the length of the trench. [0003] The bottom of the existing pipeline is hollowed out by excavating the soil on both sides of the pipeline. When the two pipelines are too close to be put into the bucket, the soil at the bottom of the pipeline needs to be manually hollowed out. [0004] With regard to the related technologies mentioned above, the inventor believes that there are defects that the steel sheet piles cannot be inserted into the grooves between adjacent pipes, the efficiency of manua...
