Description

Technical Field

[0001] The invention relates to the technical field of pipe jacking construction equipment, and in particular to a pipe jacking construction device and method. Background Art

[0002] Pipe jacking is a pipeline burial construction technology that does not involve excavation or requires minimal excavation. In the working pit, the jacking force generated by the jacking equipment overcomes the friction between the pipeline and the surrounding soil, pushes the pipeline into the soil according to the designed slope, and removes the soil. After one section of the pipe is pushed into the soil, the second section of the pipe is pushed in. Due to the restrictions of the surrounding environment, especially the traffic relief at busy intersections and the relocation of underground pipelines,

When the technical solution is in use, the position of the pipeline segment is adapted to the position of the jacking assembly, and then the locking connector is unlocked by driving the adjusting member to separate the pipeline segment from the U-shaped lifting frame and synchronously dock the jacking assembly, so that the pipeline segment is pushed in by the jacking assembly, that is, the positioning and adjustment of the lifted pipeline segment are completed passively and sequentially. With respect to the above technical solution, although the solution realizes the positioning and adjustment of the pipeline segment, the sliding distance cannot be adjusted during use, so that the jacking construction of long-distance pipelines cannot be performed, which is inconvenient during use.

[0014] A jacking construction method, the construction method is applied to a jacking construction device, and the construction method comprises the following steps:

[0015] Step 1: Dig a starting well and a receiving well at both ends of the jacking pipe burying path, then install the base in the starting well, and pull the support assembly to match the length of the jacking pipe according to the designed length of the jacking pipe, and then adjust the position of the movable seat in advance according to the designed diameter of the jacking pipe, so that the movable plate and the two support plates form an upper and lower height misalignment;

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In a jacking construction device and method of the present invention, when in use, the support assembly is adjusted to expose different lengths according to the different internal diameters of the jacking pipe or the different moving distances of the jacking pipe. The adjustment of the position of the support assembly can complete the jacking of long-distance pipelines, and the pushing mechanism is connected to the support plate, and the displacement mechanism is connected to the movable plate.

During jacking, the three points apply force synchronously to avoid the tilting of the jacking pipe caused by uneven force on the pipeline. At the same time, when the device is not used in the later stage, the support assembly can be moved and retracted to the inside of the base for storage to reduce the occupied space. Therefore, the present invention is easy to use, has a stable working process, and has low limitations.

[0020] 2. In a jacking construction device and method of the present invention, the guide rail is pulled out from the inside of the fixed groove to complete the initial distance adjustment. While the jacking pipe is being pushed in, the slide rail is adjusted for the second time on the guide rail to increase the distance of the sliding support of the jacking pipe. At the same time, the guide rail can be retracted and limited inside the fixed groove and the limit groove for storage when not in use. The storage reduces the space occupied by the entire equipment and is convenient for later movement. By setting a limit block, the slide rail is provided with an upper and lower limit force to avoid the phenomenon of the slide rail tilting up and down when moving. At the same time, when the slide rail is moved outward by the gravity of the jacking pipe, the limit block is clamped in the longitudinal groove, so that the slide rail can provide a guiding force for horizontal movement through the slide rod and the limit block when moving. Therefore, the present invention occupies a small space, is easy to use, and has high reliability.

[0021] 3. In the jacking construction device and method of the present invention, by setting a support rod, the support rod can be connected with the installation groove, so as to facilitate the fixing of the support rod. After the movable plate is moved into place, it can be connected with the support rod through the card groove at the bottom, so as to ensure that the jacking process of the jacking pipe is more stable; by setting two movable columns, the movable seat can slide up and down; by setting an inclined rod, the stability between the base and the support seat can be improved. Therefore, the working process of the present invention is stable and highly reliable. BRIEF DESCRIPTION OF THE DRAWINGS
