Problems solved by technology

[0005] However, for pipe jacking construction with long distance or increased soil friction coefficient in front of the pipeline movement, the pipeline needs to overcome the increased friction of the soil around the foundation hole, especially for the pipeline near the end of the working well, it needs to overcome the pressure of all pipelines in the foundation hole. Therefore, the pressure on the pipeline close to the end of the working well will greatly increase during the jacking process, and even exceed the pipeline's own pressure resistance, resulting in pipeline damage

Embodiment 1

[0047] like figure 1 , 2 As shown, a municipal road sewer pipeline construction equipment includes a hydraulic cylinder 1 for pushing the pipeline 10 into the foundation hole 92 , and the hydraulic cylinder 1 is arranged at the bottom of the working well 91 . It also includes a frame 2 on which a traction mechanism is arranged; the traction mechanism includes a winding wheel 31 , a stay rope 32 and a working head 33 . The reel 31 is rotated and arranged on the frame 2, and the frame 2 is provided with a driving source 21 for driving the reel 31 to rotate; Wire wheel 31 is coaxially fixedly connected.

[0048] like figure 1 , 2 As shown, an extension rod 22 is fixedly arranged on the frame 2 , and a guide wheel 221 for guiding the pull cord 32 is rotatably arranged on the extension rod 22 . The frame 2 is arranged at one end away from the working well 91 , and the guide wheel 221 is located obliquely above the foundation hole 92 . One end of the stay rope 32 is wound on t...

Embodiment 2

[0070] A construction method for municipal road sewer pipeline 10, comprising the following steps:

[0071] S1, excavating the working well 91;

[0072] S2. Excavating the foundation hole 92 for the pipeline 10 through the earth pressure balance pipe jacking machine;

[0073] S3, install the hydraulic cylinder 1 and the laying track at the bottom of the working well 91, and install the municipal road sewer pipeline 10 construction equipment at the foundation hole 92 at one end of the working well 91;

[0074] S4. Lift the pipeline 10 to the track under the working well 91, and push the pipeline 10 into the foundation hole 92 through the hydraulic cylinder 1;

[0075] S5. Lower the working head 33 from the end of the base hole 92 away from the working well 91 into the base hole 92, and then drive the working head 33 to move to the end close to the working well 91 through the traveling mechanism 4, and continue to move to the base hole 92 When the pipe 10 is jacked in, drive t...

Abstract

The invention relates to a municipal road sewer pipeline construction device and method, and belongs to the technical field of municipal road construction. The device comprises a hydraulic cylinder used for jacking a pipeline into a base hole, and further comprises a machine frame, a traction mechanism is arranged on the machine frame, the traction mechanism comprises a winding wheel, a pull ropeand a work head, the winding wheel is rotationally arranged on the machine frame, the machine frame is provided with a driving source, the work head is provided with a walking mechanism, a driving part used for being in abutting connection with the end of the pipeline is arranged on the work head in a sliding mode, and the work head is provided with a driving assembly used for driving the drivingpart to slide. In the work process, the driving source is started, the driving source drives the winding wheel to rotate, the pull rope pulls the work head, the driving block abuts against the end face, close to a work shaft, of the pipeline, and the pipeline is pulled to advance. The pipeline at the end close to the work shaft is prevented from being subjected to friction resistance force broughtby all pipelines in the base hole, and damage caused by excessive pressure to the pipeline in the jacking process is prevented.

Description

technical field [0001] The invention relates to the technical field of municipal pipeline construction, in particular to a municipal road sewer pipeline construction equipment and construction method. Background technique [0002] In municipal engineering, there are often pipeline construction operations. The area of ​​the city is getting larger and larger, and the transportation area that the municipal sewer pipes need to cover is also increasing, so it is necessary to continuously add municipal drainage pipes. [0003] The construction of general municipal drainage pipelines is carried out through the steps of excavating trenches, hoisting municipal water supply pipelines, and backfilling trenches. Such a construction method requires transporting municipal water supply pipelines to the construction site. This construction method needs to excavate the pipe trench from the ground in advance, which will affect the normal traffic of the road for the construction environment o...
