Description

Technical Field

[0001] This utility model relates to the field of pipe jacking construction technology, and in particular to a pipe jacking construction jacking guide device. Background Technology

[0002] Pipe jacking is a trenchless method for laying underground pipelines, widely used in municipal pipeline networks, power cables, and optical fiber cables. This method involves applying thrust within a working pit to push the pipe section by section into the soil, avoiding the damage to surface traffic, the environment, and facilities caused by traditional open-cut construction. However, existing pipe jacking guidance devices still suffer from limitations in accurately guiding the jacking process and in preventing damage to the pipe under stress during jacking.

[0003] Therefore, it is essential to invent a jacking guide device for pipe jacking construction. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a pipe jacking construction guiding device, which solves the issues that existing pipe jacking construction guiding devices still cannot accurately guide the jacking process and cannot prevent damage to the pipe under stress during jacking. A pipe jacking construction guiding device includes a supporting base plate, a hydraulic structure, a hydraulic push rod, a pushing structure, a guide base, and a pipe. The hydraulic structure is fixedly installed at one end of the supporting base plate, and the hydraulic push rod is fixedly installed on the hydraulic structure and located on the surface of one end of the supporting base plate. The pushing structure is fixedly installed at one end of the hydraulic push rod. The guide base is fixedly installed on the surface of the other end of the supporting base plate, and the pipe is placed on the surface of the guide base.

[0005] The supporting base plate includes a supporting base, a sliding track, a ground support plate, a connecting pipe, and anti-displacement ground nails. The sliding track is fixedly installed on the surface of the supporting base, and a pushing structure is slidably installed on the sliding track. The ground support plate is fixedly installed at the bottom of the supporting base, and the connecting pipe is installed inside the ground support plate. The anti-displacement ground nails are slidably installed inside the connecting pipes and are connected and fixed to the connecting pipes at the top.

[0006] The pushing structure includes a movable base, a sliding base, a connecting body, a connecting frame, and a positioning seat. The movable base is fixedly installed at one end of the hydraulic push rod, and the sliding base is fixedly installed below the movable base and slidably installed on the sliding rail. The connecting body and the connecting frame are fixedly installed in front of the movable base, and the positioning seat is fixedly installed in front of the connecting body and the connecting frame.

[0007] The ground support plate inside the supporting base plate is made of a steel metal plate, and the ground support plate is in contact with the ground. There are two sets of supporting base and sliding rails, which are distributed on both sides of the surface of the ground support plate. The connecting pipe is made of several metal pipes, and the top of the connecting pipe is fixedly installed with a connecting flange. The connecting pipe is tilted in the opposite direction to the hydraulic push rod. The anti-displacement ground nail is inserted obliquely into the ground through the tilted connecting pipe.

[0008] The positioning seat inside the pushing structure uses two sets of arc-shaped steel metal parts, and the inside of the positioning seat is provided with an arc-shaped groove. The arc-shaped groove inside the positioning seat is consistent with the curvature of the jacking pipe. The arc-shaped groove inside the positioning seat can be locked onto the wall of the jacking pipe. The pushing structure can be moved by the push of a hydraulic push rod.

[0009] Compared with the prior art, the present invention has the following beneficial effects: The support base plate of this utility model provides a stable installation platform for the hydraulic structure, hydraulic push rod, pushing structure and guide base, and provides precise guidance for the sliding base of the pushing structure through its sliding track; at the same time, the jacking load is distributed by the ground support plate, and the foundation is anchored by the inclined connecting pipe and anti-displacement ground nails, which effectively resists the reaction force generated by the hydraulic push rod and ensures the stability and directional accuracy of the pipe jacking process.

[0010] The propulsion structure of this utility model receives the thrust transmitted by the hydraulic push rod through its movable base, and moves directionally along the sliding track of the support base plate through the sliding base. Finally, the thrust is transmitted to the positioning seat through the connecting body and the connecting frame. The arc groove inside the positioning seat clamps the pipe wall of the jacking pipe, thereby realizing the effective transmission and uniform distribution of the thrust, thus ensuring that the jacking pipe (6) is pushed in smoothly and accurately along the guide base.

[0016] As attached Figure 1 To be continued Figure 3 As shown.

[0017] This utility model provides a jacking guide device for pipe jacking construction, comprising a supporting base plate 1, a hydraulic structure 2, a hydraulic push rod 3, a pushing structure 4, a guide base 5, and a jacking pipe 6.

[0018] The supporting base plate 1 includes a supporting base 11, a sliding rail 12, a ground support plate 13, a connecting pipe 14, and anti-displacement ground nails 15. The sliding rail 12 is fixedly installed on the surface of the supporting base 11, and a pushing structure 4 is slidably installed on the sliding rail 12. The ground support plate 13 is fixedly installed at the bottom of the supporting base 11, and the connecting pipe 14 is installed inside the ground support plate 13. The anti-displacement ground nails 15 are slidably installed inside the connecting pipe 14 and are connected and fixed to the connecting pipe 14 at the top.

[0019] The pushing structure 4 includes a movable base 41, a sliding base 42, a connecting body 43, a connecting frame 44, and a positioning seat 45. The movable base 41 is fixedly installed at one end of the hydraulic push rod 3. The sliding base 42 is fixedly installed below the movable base 41 and slidably installed on the sliding rail 12. The connecting body 43 and the connecting frame 44 are fixedly installed in front of the movable base 41, and the positioning seat 45 is fixedly installed in front of the connecting body 43 and the connecting frame 44.

[0020] The ground support plate 13 inside the supporting base plate 1 is made of a steel metal plate, and the ground support plate 13 is in contact with the ground. The supporting base 11 and the sliding track 12 are in two sets and are distributed on both sides of the surface of the ground support plate 13. The connecting pipe 14 is made of several metal pipes, and a connecting flange is fixedly installed on the top of the connecting pipe 14. The connecting pipe 14 is tilted in the opposite direction to the hydraulic push rod 3.

The arc-shaped groove inside the positioning seat 45 can be locked on the wall of the top pipe 6. The pushing structure 4 can be moved by the push of the hydraulic push rod 3.

[0022] The working principle of this pipe jacking construction jacking guide device begins with foundation fixing and load transfer: the support foundation plate 1 disperses the vertical load through its ground support plate 13, and resists the jacking reaction force through the anti-displacement ground nails 15 inserted obliquely into the ground; the jacking pipe 6 to be jacked is placed on the guide base 5 to complete the initial positioning and form a stable working foundation.

[0023] The power propulsion and directional jacking process is driven by the hydraulic structure 2 to extend the hydraulic push rod 3, which pushes the moving base 41 of the push structure 4, so that the sliding base 42 slides directionally along the sliding track 12; finally, the thrust is transmitted to the positioning seat 45 through the connecting body 43 and the connecting frame 44, and its arc groove clamps the pipe wall of the jacking pipe 6, so as to achieve uniform distribution of thrust and precise jacking.
