[0002] Pipe jacking technology is a non-excavation, excavation-type pipe laying technology used in municipal construction. Its advantages are that it has no impact on the surrounding environment or has little impact, a small construction site, and low noise. Pipe jacking technology is often used to build tunnels during subway construction. When using pipe jacking technology, the pipes that have not yet been extended need to be supported. However, the traditional pipe jacking construction support device used in subway construction has a single function. It is not convenient to quickly adjust the height of the pipe according to construction needs, nor is it convenient to adjust the lateral movement of the pipe. At the same time, it cannot reduce the friction between the pipe and the support device, making it difficult to meet the needs of fast and convenient adjustment, and is not conducive to accurate and rapid pipe jacking technology construction.

[0003] In order to solve the above problems, we propose a pipe jacking construction support device for subway construction, which improves the shortcomings of the existing technology. Utility Model Content

[0017] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0018] Example

[0019] like Figure 1-3 As shown, a jacking pipe construction support device for subway construction includes a support plate 1, a laterally movable support frame 2 is arranged above the support plate 1, two side pressure cylinders 3 are fixed on the inner walls on both sides of the support frame 2, and a side extrusion frame 4 is fixed on the protruding ends of the two side pressure cylinders 3 on the same side, a rotating rod 5 is connected between the inner walls of the upper and lower ends of the side extrusion frame 4 through a bearing, and a side limiting roller 6 is sleeved and fixed on the rotating rod 5, two bottom supporting cylinders 7 are fixed on the inner wall of the bottom of the support frame 2, and a bottom supporting frame 8 is fixed on the protruding ends of the two bottom supporting cylinders 7, and the inner walls on both sides of the bottom supporting frame 8 A rotating rod 29 is connected therebetween through a bearing, and a bottom support roller 10 is mounted and fixed on the rotating rod 29. Two vertical plates 12 and a propulsion cylinder 13 are fixed to the upper surface of the support plate 1. Two parallel guide slides 14 are welded and fixed between the two vertical plates 12. Support slides 11 mounted on the guide slides 14 are welded and fixed at both ends of the bottom of the support frame 2. The protruding end of the propulsion cylinder 13 is fixed to the outside of one of the support slides 11, forming an overall structure of the jacking pipe construction support device for subway construction. It has comprehensive functions, strong adjustability, can meet the construction support needs, and is conducive to accurate and rapid jacking technology construction.

[0020] In this embodiment, two through holes 15 are provided at the bottom of the support slide 11, and the guide slide rod 14 passes through the corresponding through holes 15. The support slide 11 can slide laterally along the guide slide rod 14, making it convenient to use the propulsion cylinder 13 to push the support frame 2 laterally, thereby making a large-scale laterally adjustment to the tube.

[0021] In this embodiment, a support leg 16 is welded and fixed to the bottom of the support plate 1 to firmly support the device in the construction pit.

[0022] In this embodiment, a controller 17 is further provided on one side wall of the support frame 2, and the controller 17 is electrically connected to the side pressure cylinder 3, the bottom support cylinder 7 and the propulsion cylinder 13 for controlling the operation of the device.

[0023] In this embodiment, the two side pressure cylinders 3 on the same side operate synchronously to ensure that the side limiting rollers 6 maintain vertical movement, and the two bottom support cylinders 7 move synchronously to ensure that the bottom support rollers 10 maintain horizontal movement.

[0024] The principle and advantages of the utility model are as follows: the subway construction pipe jacking support device is hoisted into the construction pit by a crane, the controller 17 is connected to the power supply to control the operation of the device, and then the control device 17 is connected to the power supply to control the operation of the device. Figure 2 As shown, one end of the pipe is placed on the bottom support roller 10, and the side pressure cylinder 3 is turned on to push the side limit roller 6 inward. The side limit roller 6 is used to push the pipe to slide on the bottom support roller 10 and move it laterally in a small range. The propulsion cylinder 13 can also be turned on to directly push the support frame 2, and the support frame 2 is used to move the pipe laterally in a large range. The bottom support cylinder 7 is turned on to push the bottom support roller 10 to rise, thereby adjusting the height of the pipe. After the adjustment is completed, the two side limit rollers 6 are clamped on both sides of the pipe to prevent the pipe from moving again, thereby improving the accuracy of the jacking construction, thereby supporting and positioning it. Since the side limit rollers 6 and the bottom support rollers 10 can both rotate, the friction force can be reduced when the pipe is pushed, which helps to increase the pushing force of the pipe. The jacking construction support device for subway construction using this structural design is comprehensive in function and has strong adjustability. It can meet the construction support needs and help to accurately and quickly carry out jacking technology construction, thereby improving practicality.
