Pipe-roofing push bench provided with lock guiding devices and attitude control method thereof

Abstract

The invention discloses a pipe-roofing push bench provided with lock guiding devices and an attitude control method thereof. The push bench comprises a push bench housing and the lock guiding devices. The lock guiding devices are mounted on the tail portion of the side surface of the push bench housing. Each lock guiding device comprises a wedge-shaped protection block projecting towards the outer side of the push bench housing; the thickness of the front end of the wedge-shaped protection block is less than the thickness of the rear end of the wedge-shaped protection block; and the front end of the wedge-shaped protection block points to the head portion of the push bench housing. During a steel pipe section jacking process, the lock guiding devices block the front ends of locks on the outer side of a steel pipe section, so that a phenomenon that the locks deform as the locks touch hard materials such as rocks can be avoided, and the resistance of the steel pipe section during the jacking process can be reduced.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a pipe curtain pipe jacking machine with a locking guide device and a posture control method thereof. Background technique [0002] With the development of urban construction, the population density has increased significantly, and there are more and more means of transportation. Urban traffic congestion restricts urban development. The pipe-curtain underground excavation method has become the research focus of underground space excavation. The pipe curtain construction method is a kind of non-excavation process. During the excavation process, the jacking device of a small-diameter pipe jacking machine is used to insert steel pipes horizontally into the space to be excavated to form a pipe curtain. [0003] Such as figure 1 As shown, the pipe jacking machine 901 is installed at the front end of the steel pipe section 902 during the construction of the pipe curtai...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the steel pipe section 902 provided with buckles has the following problems in the process of jacking into the soil layer: 1. The lock 903 protrudes from the side of the steel pipe section 902, so that the front end of the lock 903 is in the jacking process. Squeeze the soil directly, which will increase the resistance encountered during the jacking process of the steel pipe section 902; 2. When the soil layer contains hard foreign matter, when the front end of the lock 903 directly touches the foreign matter, it will cause the front end of the lock 903 to Deformation occurs, which leads to the failure of the locking buckle 903 between the steel pipe sections 902, which affects the water-stopping effect of the pipe curtain
