Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: the pipe jacking machine currently used in water conservancy projects usually has a fixed base. When the installation height of the pipeline is different, the base cannot adapt to the change in the installation height of the pipeline. Or continue to dig deep working pits to finally achieve the purpose of installing pipelines. The operation is time-consuming, so the existing pipe jacking machines still need to be improved

Embodiment Construction

[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0035] like figure 1 As shown, it is a pipe jacking machine for hydraulic engineering disclosed by the present invention, which includes a base 1 and a pipe jacking body 2, the upper part of the base 1 is connected with an adjustment seat 3, and the pipe jacking body 2 is installed on the adjustment seat 3; the adjustment seat 3 A support plate 31 is fixed on one side of the support plate 31, and two relative drive cylinders 4 are fixed on the support plate 31, and the drive cylinder 4 extends along the side away from the support plate 31. The push rod 41 inserted on the side wall of the push plate 5 is fixed on the drive cylinder 4 on the plate 5 , and the push plate 5 abuts against the pipe jacking body 2 .

[0036] like figure 1 , 2 As shown, the support plate 31 is movably connected to the base 1 through the connection structure 6, so that the adjustme...

Abstract

The invention relates to the technical field of water conservancy engineering construction equipment, and discloses a pipe jacking machine for water conservancy engineering, which includes a base and a pipe jacking body mounted on the base. On the seat, the base is provided with a support device for supporting the adjustment seat. The support device includes an abutment plate and an overlay plate. The side wall of the base is provided with a movable groove for accommodating the abutment plate. Several overlay plates are connected to the abutment plate. And the abutment plate rotates to abut against the upper part of the base and supports the bottom of the adjustment seat. The present invention has the following advantages and effects: when the abutment plate rotates in the movable groove to abut against the bottom plate, it can stably support the adjustment seat, making the structure of the adjustment seat more stable after it rises; The superimposition of the boards continues to increase the height of the support, and the adjustment seat is stably supported at different heights, without the need for manual landfill or continued deep digging of the work pit, saving man-hours and expanding the scope of application of the pipe jacking machine.

Description

technical field [0001] The invention relates to the technical field of hydraulic engineering construction equipment, in particular to a pipe jacking machine for hydraulic engineering. Background technique [0002] The pipe jacking machine is a pipeline burying construction technology that does not excavate or excavates less. The pipe jacking method is to use the jacking force generated by the jacking equipment in the working pit to overcome the friction between the pipeline and the surrounding soil, and the pipeline is placed according to the design. The slope is jacked into the soil, and the earth is transported away. After one section of pipe is pushed into the soil layer, the second section of pipe is continued to jack. [0003] At present, the patent with the publication number CN105201522A discloses an earth pressure balance pipe jacking machine, which includes: a cutting cutterhead, the back of which is provided with a soil bin; a cutterhead driving mechanism, which in...
