Referring to fig. 1, a temporary pipe joint 10 in an embodiment is used for temporarily replacing an actual pipe joint in pipe jacking construction. Specifically, the temporary pipe joint 10 includes a pipe body 100, a gap 110 communicating with an inner cavity of the pipe body 100 is formed in a side wall of the pipe body 100, and the gap 110 extends through end faces of two ends of the pipe body 100 along an axial direction of the pipe body 100.
Specifically, the pipe body 100 may be a steel pipe joint to meet the requirements of strength and rigidity. Of course, the tubular body 100 may be made of other materials. The inner wall of the pipe body 100 is provided with a reinforcing block 200, the reinforcing block 200 is arranged near the gap 110, and the reinforcing block 200 supports the pipe wall near the gap 110 through a support rod 210. The reinforcing block 200 can ensure the strength and rigidity of the pipe wall at the notch 110 by matching with the supporting rod 210, and the deformation of the pipe body 100 is avoided. In this embodiment, the number of the reinforcing blocks 200 is two, and the two reinforcing blocks 200 are respectively located on the pipe walls on both sides of the notch 110.
In one embodiment, the two ends of the pipe body 100 are provided with the retaining rings 300, the notch 110 penetrates through the two retaining rings 300, and the retaining rings 300 can facilitate the main cylinder of the jacking device to jack the temporary pipe joint 10. The outer wall of body 100 is equipped with a plurality of reinforcing strips 310 along the interval on the circumferential direction, and two dogs are connected respectively to reinforcing strip 310's both ends, and reinforcing strip 310 extends along the axial direction of body 100. The reinforcing strips 310 can increase the strength of the pipe body 100 in the axial direction, avoid the pipe body 100 from being crushed in the jacking process of the jacking equipment, reduce the wall thickness of the pipe body 100, save the material of the temporary pipe joint 10 and reduce the cost.
In one embodiment, the outer wall of the pipe body 100 is provided with a support lug 400, and the support lug 400 is provided with a hoisting hole 410, so that the temporary pipe joint 10 can be conveniently hoisted by a hoisting tool. Specifically, the number of the lugs 400 is two, and the two lugs 400 are arranged at intervals in the axial direction of the pipe body 100. The notch 110 and the lug 400 are located in the same radial direction of the pipe body 100, so that when the temporary pipe joint 10 is hoisted, the notch 110 faces downward, and various pipelines can conveniently enter the pipe body 100 through the notch 110.
In one embodiment, two sets of sliding blocks 500 are disposed on the outer wall of the tube 100, and the two sets of sliding blocks 500 are respectively disposed on the tube walls at two sides of the notch 110. Specifically, the number of each set of the sliding blocks 500 is two, and the two sliding blocks 500 in the same set are arranged at intervals along the axial direction of the pipe body 100. Be equipped with guider in the working well, slider 500 can with guider sliding fit, guarantee that interim tube coupling 10 jacking in-process direction can not appear deflecting. In this embodiment, the guiding device in the working well is two spaced steel sleepers.
Referring to fig. 2, the present invention further provides a pipe-jacking construction method, which uses the temporary pipe joint 10. Specifically, the pipe jacking construction method comprises the following steps:
step S110: the jacking equipment retracts into the main jacking oil cylinder to create space, and the temporary pipe joint 10 is hoisted to the guide device.
Specifically, when the working well is designed, the windowing degree of the working well should be designed, and 3-4 pipe joints can be exposed out of the working well in the jacking process in the jacking construction process. After the lifting appliance hooks the lifting holes 410 of the support lugs 400, the gap 110 of the top pipe faces downwards at the moment, the temporary pipe joint 10 is lifted to the upper side of the guide device, the temporary pipe joint 10 is gradually lowered, and finally the two groups of sliding blocks 500 of the temporary pipe joint 10 are respectively arranged on the two steel sleepers. Due to the gap 110 of the temporary pipe section 10, various pipelines can enter the temporary pipe section 10, so that the various pipelines do not need to be disassembled.
In an embodiment, before the step S110, the method further includes: the temporary pipe joint 10 is prefabricated according to the specification and the size of an actual pipe joint. Specifically, before the pipe jacking construction is started, the temporary pipe joint 10 should be manufactured in advance according to the specification and the size of the actual pipe joint. The diameter of the temporary pipe joint 10 should be the same as the diameter of the actual pipe joint, and the length of the temporary pipe joint 10 may be the same as the actual pipe joint or may be in a certain multiple relation with the length of the actual pipe joint.
Step S120: and jacking the temporary pipe joints 10 through the main jacking oil cylinder of the jacking equipment, and enabling the temporary pipe joint 10 closest to the tunnel not to jack into the tunnel.
Specifically, the temporary pipe joints 10 are hoisted in sequence, and each temporary pipe joint 10 is jacked in sequence. The number of temporary pipe sections 10 to be jacked in depends on the length of the working well. In the embodiment, the main jacking oil cylinder of the jacking device jacks 2-3 temporary pipe joints 10, so that the windowing degree of the working well is moderate, and the working well is prevented from being dug in a transitional manner.
Step S130: and lifting the temporary pipe joints 10 away, dismantling various pipelines, installing a plurality of pipe joints which need to be jacked in actually, and finally reinstalling the pipelines.
Specifically, the lifting appliance can lift all the temporary pipe joints 10 away at one time, the time for lifting the temporary pipe joints 10 by the lifting appliance is short, and the construction period of pipe jacking construction is basically not influenced. And then various pipelines are dismantled, a plurality of pipe joints which need to be jacked in are installed at one time after the various pipelines are dismantled, and finally the pipelines are reinstalled. In the embodiment, 2-3 pipe joints which need to be pushed in actually can be installed at one time. And then repeating the process until the pipe jacking construction is completed.
The temporary pipe joint 10 and the pipe jacking construction method at least have the following advantages:
because the temporary pipe joints 10 are provided with the gaps 110, various pipelines do not need to be disassembled when the plurality of temporary pipe joints 10 are jacked, and then jacking equipment jacks the plurality of temporary pipe joints 10, so that the temporary pipe joint 10 closest to the tunnel is not jacked into the tunnel. And then, hoisting the temporary pipe joint 10 away, installing the actual pipe joint needing to be jacked in, and installing and dismantling various pipelines in the process. Because the time spent on hoisting the temporary pipe joints 10 is short, a plurality of actual pipe joints can be jacked in by installing and disassembling the pipeline once, a large amount of time and labor cost are saved, and the construction period is shortened.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
