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] Such as 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] Such as 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 woun...

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 equipment and construction method, belonging to the technical field of municipal pipeline construction, including a hydraulic cylinder for jacking the pipeline into a foundation hole, and a frame, on which a traction mechanism is arranged; the traction mechanism It includes a reel, a pull rope and a working head. The reel is rotated and set on the frame, and the drive source is set on the frame; the working head is provided with a walking mechanism; The driving part of the working head is provided with a driving assembly for driving the sliding of the driving part. When working, start the driving source, and the driving source drives the winding wheel to rotate, so that the pull rope pulls the working head, makes the driving block and the end face of the pipeline near the working well close together, and pulls the pipeline forward; avoid the pipeline near the working well end being affected by the base The friction resistance brought by all the pipes in the hole prevents the pipe from being damaged due to excessive pressure during the jacking process.

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...
