Embodiment 1

[0042]Such asFigure 1 to Figure 5Shown: an auxiliary device that can adjust the force of a jacking pipe, including a jacking pit 1, a jacking pipe 2, and a jack 3, and also includes a limit rod 4, a first connecting plate 5, a second connecting plate 6 and a fitting piece , The limit rod 4 is provided with a groove, the shell body of the jack 3 is installed in the groove, one side of the first connecting plate 5 is bolted to the wall of the jacking pit 1, and the other side of the first connecting plate 5 is connected with Limit rod 4 welding;

[0043]The second connecting plate 6 is located on the end of the limiting rod 4 away from the first connecting plate 5. The second connecting plate 6 is welded to the plunger of the jack 3, and the side of the jack 3 opposite to the plunger is welded to the first connecting plate 5. ;

[0044]The fitting includes an arc-shaped crawler frame 7 and a push cylinder 8. The arc-shaped crawler frame 7 is located on the side of the second connecting plat...

Embodiment 2

[0061]Such asFigure 6 As shown, the installation method of the arc-shaped upper piece 71 and the arc-shaped lower piece 72 is changed to the groove and convex groove at the connection, and a stop is provided at the end of the groove away from the second connecting plate 6. The arc-shaped upper piece One side of the connection of 71 is a groove, and the other side of the connection of the arc-shaped upper piece 71 is a convex groove. Similarly, the two sides of the connection of the arc-shaped lower piece 72 are respectively provided with convex grooves and grooves, convex grooves and concave grooves. Groove insertion, the arc-shaped upper piece 71 and the arc-shaped lower piece 73 become a combined installation, and the stop is suitable for blocking the convex groove from punching out of the groove after being forced by the top tube 2. The arc-shaped upper piece 71 and the arc-shaped lower piece The piece 72 is glued to the second connecting plate 6 after the insertion is completed;...

Abstract

The invention discloses an auxiliary device capable of adjusting jacking pipe stress and a construction method, and belongs to a jacking pipe jacking construction method. The auxiliary device comprises a jacking pipe pit, a jacking pipe, a jack, a limiting rod, a first connecting plate, a second connecting plate and a fitting piece, wherein a groove is formed inside the limiting rod, a shell bodyof the jack is installed inside the groove, one side surface of the first connecting plate is fixedly connected with the wall of the jacking pipe pit, and the other side surface of the first connecting plate is fixedly connected with the limiting rod; the second connecting plate is located at the end, away from the first connecting plate, of the limiting rod, the second connecting plate is fixedlyconnected with a plunger of the jack, and the side, back to the plunger, of the jack is fixedly connected with the first connecting plate; and the fitting piece comprises an arc-shaped crawler frameand push cylinders, the arc-shaped crawler frame is located on the side, back to the jack, of the second connecting plate, and the push cylinders are evenly distributed inside the arc-shaped crawler frame. According to the auxiliary device, the problem of later-period maintenance such as cracks caused by different jacking force distribution of the jacking pipe is solved, so that the probability ofcracking of the jacking pipe is reduced, and the problems such as the later-period maintenance cost are reduced.

Description

Technical field[0001]The technology of the present invention belongs to a construction method for pipe jacking, in particular to a construction method of an auxiliary device capable of adjusting the force of a pipe jacking.Background technique[0002]Pipe jacking construction is increasingly used by design and construction units at home and abroad. The use of pipe jacking not only avoids the disadvantages of destroying the original road infrastructure, but also helps to alleviate the traffic conduction problems caused by the excavation surface. Through the application of pipe jacking technology, the construction of municipal road rain and sewage pipes can be realized more conveniently and quickly, which greatly reduces the construction period and is more beneficial to construction operations.[0003]However, there are some uncontrollable factors in the specific construction process. For example, the intersection of pipelines in unknown areas exists underground, and general detection ins...
