Description

Technical Field

[0001] The utility model patent relates to the technical field of pipe jacking construction, and specifically to a high-precision pipe jacking construction device with adjustable inclination angle using existing supports in a foundation pit. Background Art

[0002] Pipe jacking construction is a method of underground pipeline construction developed after shield construction. This construction technology has been widely used in urban road and tunnel construction. This method does not require excavation of the surface layer and can cross roads, railways, rivers, ground buildings, underground structures, etc. These pipe jacking projects are often shallowly buried, which puts forward higher requirements for posture control during pipe jacking construction. The existing pipe jacking construction technology realizes the excavation of tunnels or pipelines through the organic coordination of various components such as the machine head, rear jacking equipment, electrical control system and screw conveyor. However, since the posture of the pipe jacking machine is only controlled by the rear jacking equipment at the tail of the pipe jacking machine, it is difficult to achieve precise control of the construction, which leads to shallow or ultra-shallow soil overburden due to excessive jacking thrust during the jacking process, resulting in ground uplift and even sudden changes in the posture of the pipe jacking machine. Therefore, high-precision adjustment during pipe jacking construction is a crucial part of the construction process.

[0003] In addition to the difficulty in accurately controlling the construction angle during the above-mentioned pipe jacking construction process, the pipe jacking construction process requires the construction of a complex manually operated construction platform, which means that a lot of manpower and material resources are required. The construction process of underground structures often involves the excavation of foundation pits and the construction of pipe jacking in sequence. When constructing shallow or ultra-shallow soil pipe jacking, the existing support of the foundation pit is used, which can effectively reduce the waste of a lot of manpower and material resources caused by the construction of the construction site, thereby achieving the goal of green environmental protection.

[0004] Therefore, in view of the above problems, it is urgent to propose a high-precision pipe jacking construction device and method that utilizes the inclination angle of the existing support of the foundation pit and can be adjusted. Utility Model Content

[0011] Preferably, the bottom plate locking mechanism comprises a clamping plate, which clamps the concrete support body from bottom to top, and both ends of the clamping plate are fixedly connected to the bottom plate upward.

[0012] Preferably, the support seat mechanism includes two base plates, four clamping plates, and sixteen bolts. Every two clamping plates are respectively attached to and bypass the concrete support. The two ends of the clamping plates are fixedly connected to the base plate bolts by two bolts respectively. The first hydraulic jack and the second hydraulic jack are controlled by the first motor and the second motor. The pitch angle of the circular sleeve is adjusted by the first hydraulic jack and the second hydraulic jack to realize the inclination angle control during the jacking process of the jacking pipe.

[0013] Preferably, the GPS positioning module is installed above the jacking pipe, and the latest position information of the jacking pipe is obtained through the GPS positioning module to grasp the progress of the jacking pipe construction.

Installing an inclinometer can more accurately control the inclination of the jacking pipe. Installing a GPS positioning module can also grasp the progress of the jacking pipe construction, remotely locate the device through a computer, obtain the latest location information, and make timely adjustments.
