Description

Technical Field

[0001] The present invention belongs to the technical field of pipe jacking, and particularly relates to a stainless steel collar for pipe jacking. Background Art

[0002] Pipe jacking technology is a non-excavation pipe-laying construction technology used for municipal construction. Its advantages are that it has little or no impact on the surrounding environment, requires a small construction site, and produces little noise. Moreover, it can work deep underground, which is an advantage that cannot be compared with open-cut pipe burying.

[0003] Existing pipe jacking operations also have defects, such as long construction time and high project cost. The existing stainless steel collars (stop rings) for pipe jacking construction are sized to fit the pipe jacking, and can only be used in a matching manner, which is very troublesome. Moreover, the existing stop rings can only reduce the jacking resistance, and their functions are relatively single. Therefore, the present invention proposes a stainless steel collar for pipe jacking to solve the above problems. Summary of the Invention

[0004] The present invention provides a stainless steel collar for pipe jacking, aiming to solve the problems raised in the background art.

[0005] The present invention is implemented as follows: A stainless steel collar for pipe jacking includes a first collar and a second collar;

[0006] The first collar and the second collar are connected by a connecting rod. The first collar is arranged on the outer wall of the first pipe jacking, and the second collar is arranged on the outer wall of the second pipe jacking;

[0007] The first collar includes a collar housing. A fixing plate is arranged on the rear side surface of the collar housing. A moving plate is arranged inside the fixing plate. The side surface of the moving plate away from the fixing plate is of an arc structure. A threaded rod is arranged on the moving plate, and the threaded rod is screwed with the fixing plate. An anti-slip pad is arranged on the side surface of the moving plate away from the fixing plate.

[0008] Preferably, a plurality of fixing plates are provided, and the plurality of fixing plates are arranged at intervals in a circular ring shape.

[0009] Preferably, a plurality of moving plates are provided, and the plurality of moving plates are arranged at intervals in a circular ring shape, and the moving plates correspond to the fixing plates one by one.

[0010] Preferably, a nut is arranged outside the fixing plate, and the nut is screwed with the threaded rod.

[0011] Preferably, the inner side surface of the fixing plate is of an arc structure.

[0012] Preferably, the anti-slip pad is connected to the outer wall of the pipe jacking.

[0013] Preferably, the distance between the fixed plate and the moving plate is adjusted by rotating the nut.

[0014] Preferably, a limit block is provided on the threaded rod, and the limit block is used to limit the length of the threaded rod extending beyond the outer diameter of the sleeve housing.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] A nut is provided on the outer side of the fixed plate, and the nut is screwed onto the threaded rod. By rotating the nut, the distance between the fixed plate and the moving plate is adjusted. Assuming that the nut is rotated clockwise to increase the distance between the fixed plate and the moving plate, then the nut is rotated counterclockwise to decrease the distance between the fixed plate and the moving plate. The first sleeve and the second sleeve are two identical sleeves. During installation, the nut is rotated counterclockwise to decrease the distance between the fixed plate and the moving plate. Then, after the two jacking pipes are connected, the first sleeve is disposed on the outer wall of the first jacking pipe, and the second sleeve is disposed on the outer wall of the second jacking pipe. Then, the nut is rotated clockwise to increase the distance between the fixed plate and the moving plate. When the anti-slip pad contacts the outer wall of the jacking pipe, stop rotating the nut. Repeat the operation to adjust all the moving plates to be connected to the outer wall of the jacking pipe. At this time, the first sleeve and the second sleeve are connected to the two jacking pipes, and the sleeve and the jacking pipe are fixed together, which can reduce the contact area between the pipe body of the jacking pipe and the soil, thereby reducing the resistance during the jacking of the jacking pipe and being beneficial to improving the efficiency of the jacking pipe construction. By connecting the two jacking pipes through the provided first sleeve and second sleeve, the two jacking pipes will not fall off during construction, making the effect of the jacking pipe construction better and avoiding the jacking pipe from falling off, which affects the construction effect and efficiency. At the same time, by rotating the nut to adjust the distance between the fixed plate and the moving plate, this sleeve can be applied to the construction of jacking pipes with different diameters.

[0028] In this embodiment, a nut 8 is provided outside the fixing plate 5. The nut 8 is screwed onto the threaded rod 7. The distance between the fixing plate 5 and the moving plate 6 is adjusted by rotating the nut 8. Assuming that rotating the nut 8 clockwise increases the distance between the fixing plate 5 and the moving plate 6, then rotating the nut 8 counterclockwise decreases the distance between the fixing plate 5 and the moving plate 6. The first collar 1 and the second collar 2 are two identical collars. When setting, rotate the nut 8 counterclockwise to decrease the distance between the fixing plate 5 and the moving plate 6. Then, after the two jacking pipes are connected, set the first collar 1 on the outer wall of the first jacking pipe and set the second collar 2 on the outer wall of the second jacking pipe. Then rotate the nut 8 clockwise to increase the distance between the fixing plate 5 and the moving plate 6. Stop rotating the nut 8 when the anti-slip pad 9 touches the outer wall of the jacking pipe. Repeat the operation to adjust all the moving plates 6 to be connected to the outer wall of the jacking pipe. At this time, the first collar 1 and the second collar 2 are connected to the two jacking pipes, and the collars are fixed to the jacking pipes together, which can reduce the contact area between the pipe body of the jacking pipe and the soil, thereby reducing the resistance when pushing the jacking pipe and being beneficial to improving the efficiency of jacking pipe construction. By setting the first collar 1 and the second collar 2 to connect the two jacking pipes, the two jacking pipes will not fall off during construction, making the effect of jacking pipe construction better and avoiding the jacking pipe from falling off and affecting the construction effect and efficiency. At the same time, by rotating the nut 8 to adjust the distance between the fixing plate 5 and the moving plate 6, this collar can be applied to the construction of jacking pipes with different diameters.

[0029] Further, please refer to Figure 3 , there are multiple fixing plates 5, and the multiple fixing plates 5 are distributed at intervals in a circular shape.

[0030] Further, please refer to Figure 3 , there are multiple moving plates 6, and the multiple moving plates 6 are distributed at intervals in a circular shape, and the moving plates 6 correspond to the fixing plates 5 one by one.

[0031] In this embodiment, when setting, rotate the nut 8 counterclockwise to decrease the distance between the fixing plate 5 and the moving plate 6. Then, after the two jacking pipes are connected, set the first collar 1 on the outer wall of the first jacking pipe and set the second collar 2 on the outer wall of the second jacking pipe. Then rotate the nut 8 clockwise to increase the distance between the fixing plate 5 and the moving plate 6. Stop rotating the nut 8 when the anti-slip pad 9 touches the outer wall of the jacking pipe. Repeat the operation to adjust all the moving plates 6 to be connected to the outer wall of the jacking pipe. At this time, the first collar 1 and the second collar 2 are connected to the two jacking pipes, fixing the two jacking pipes.

[0032] Further, please refer to Figure 3 , a nut 8 is provided outside the fixing plate 5, and the nut 8 is screwed onto the threaded rod 7.

[0033] Further, please refer to the figure. Rotating the nut 8 is used to adjust the distance between the fixing plate 5 and the moving plate 6.

[0034] In this embodiment, a nut 8 is provided outside the fixing plate 5. The nut 8 is screwed onto the threaded rod 7. Assuming that the nut 8 is rotated clockwise to increase the distance between the fixing plate 5 and the moving plate 6, then the nut 8 is rotated counterclockwise to decrease the distance between the fixing plate 5 and the moving plate 6. The distance between the fixing plate 5 and the moving plate 6 is adjusted by rotating the nut 8.

[0035] Furthermore, the inner side surface of the fixing plate 5 is an arc-shaped structure.

[0036] In this embodiment, one side surface of the moving plate 6 away from the fixing plate 5 is an arc-shaped structure, and the inner side surface of the fixing plate 5 is an arc-shaped structure. In this way, the moving plate 6 and the fixing plate 5 can be closely attached to fix the jacking pipes with different apertures.

[0037] Furthermore, the anti-slip pad 9 is connected to the outer wall of the jacking pipe.

[0038] In this embodiment, the outer wall of the anti-slip pad 9 is also an arc-shaped structure and is connected to the outer wall of the jacking pipe during use. In this way, not only can the sleeve ring be prevented from detaching from the jacking pipe, but also the jacking pipe can be protected to a certain extent.

[0039] Furthermore, a limit block is provided on the threaded rod 7. The limit block is used to limit the length of the threaded rod 7 extending beyond the aperture of the outer wall of the sleeve ring housing 4.

[0040] In this embodiment, since the function of the provided sleeve ring is that the sleeve ring is fixed to the jacking pipe, which can reduce the contact area between the pipe body of the jacking pipe and the soil, thereby reducing the resistance during the jacking of the jacking pipe and being beneficial to improving the efficiency of the jacking pipe construction; therefore, the extending length of the threaded rod 7 does not exceed the aperture of the outer wall of the sleeve ring housing 4, so that the threaded rod 7 will not extend out of the outer wall of the sleeve ring housing 4 and will not increase the jacking resistance.

[0041] Working principle and usage process of the present invention: A nut 8 is provided outside the fixing plate 5. The nut 8 is screwed onto the threaded rod 7. By rotating the nut 8, the distance between the fixing plate 5 and the moving plate 6 is adjusted. Assuming that the nut 8 is rotated clockwise to increase the distance between the fixing plate 5 and the moving plate 6, then the nut 8 is rotated counterclockwise to decrease the distance between the fixing plate 5 and the moving plate 6. The first collar 1 and the second collar 2 are two identical collars. During setting, the nut 8 is rotated counterclockwise to decrease the distance between the fixing plate 5 and the moving plate 6. Then, after the two jacking pipes are connected, the first collar 1 is arranged on the outer wall of the first jacking pipe, and the second collar 2 is arranged on the outer wall of the second jacking pipe. Then the nut 8 is rotated clockwise to increase the distance between the fixing plate 5 and the moving plate 6. When the anti-slip pad 9 touches the outer wall of the jacking pipe, the rotation of the nut 8 is stopped. The above operation is repeated until multiple moving plates 6 are all adjusted to be connected to the outer wall of the jacking pipe. At this time, the first collar 1 and the second collar 2 are connected to the two jacking pipes, and the collars are fixed to the jacking pipes together, which can reduce the contact area between the pipe body of the jacking pipe and the soil, thereby reducing the resistance during the jacking of the jacking pipe and being beneficial to improving the efficiency of the jacking pipe construction. The two jacking pipes are connected by the provided first collar 1 and second collar 2, so that the two jacking pipes will not fall off during construction, making the effect of the jacking pipe construction better and avoiding the falling off of the jacking pipe, which affects the construction effect and efficiency. At the same time, by rotating the nut 8 to adjust the distance between the fixing plate 5 and the moving plate 6, this set of collars can be applied to the construction of jacking pipes with different apertures.

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
