Description

Technical Field

[0001] The invention relates to the technical field of pipe jacking construction equipment, in particular to a production process for a non-prestressed steel cylinder concrete pipe jacking construction pipeline based on laser positioning. Background Art

[0002] Pipe jacking is a trenchless method for laying underground pipelines. Pipe jacking equipment is used in a working pit to push the pipeline into the soil according to the designed slope. It is suitable for crossing complex environments such as roads, railways, and rivers, avoiding large-scale excavation. It has the advantages of high construction efficiency, little impact on ground traffic, and environmental protection and economy. It is widely used in urban water supply and drainage, gas, electricity, communications and other pipeline projects.

[0003] The patent with application number CN201610211700.4 discloses a mud and water pipe jacking machine test device, including a reaction frame and a cylinder support frame. The cylinder support frame is provided with a support guide rail. The pipe jacking machine support and the pressure-bearing device cooperate with the support guide rail. The jacking shoe and the reaction frame are connected. The pipe jacking machine support includes a load-bearing platform. The bottom of the load-bearing platform is provided with a load-bearing roller. The lower part of the sliding support block is arranged in the slide rail at the top of the load-bearing platform, and the upper part of the sliding support block is connected to the support seat; the pressure-bearing device includes a pressure-bearing cylinder fixed on the cylinder support frame, and the pressure-bearing cylinder is provided with a tunnel door water-stop seal.

[0004] However, in current concrete pipe laying operations, when the pipe needs to be delivered to the bottom of the working tunnel, it is usually necessary to rely on manual operation of the lifting structure above the tunnel. Specifically, the workers need to use wire ropes to firmly fix the pipe and then slowly deliver it to the bottom of the tunnel. At the same time, there are also workers below the tunnel responsible for operating the pipe jacking machine. After the pipe is lowered to the predetermined position, the workers below need to manually disconnect the wire rope. This process not only involves a lot of manual intervention, but also poses significant safety risks.

[0005] In view of this, we propose a production process for non-prestressed steel cylinder concrete pipe jacking construction pipeline based on laser positioning. Summary of the Invention

[0006] The purpose of the present invention is to provide a production process for non-prestressed steel cylinder concrete pipe jacking construction pipeline based on laser positioning to solve the problems raised in the above background technology.

[0011] S3. Then, the telescopic rod of the control cylinder is retracted, thereby driving the connecting frame to move away from the fixing mechanism, thereby driving the movable bracket and the fixed tooth plate to move together;

[0012] S4, when the fixed tooth plate moves, it contacts the docking gear in the outer sleeve, driving the outer sleeve ring body to rotate, and the pawls on the inner ring wall come into conflict with the ratchet;

[0053] The production process of non-prestressed steel cylinder concrete pipe jacking construction pipeline based on laser positioning includes the following steps:

[0054] S1. First, the operator at the working pit places the concrete pipe body on the transport track outside the pipeline transport device 200 and starts the cylinder 234 in the driving mechanism 230;

[0055] S2. After the cylinder 234 is activated, it drives the connecting frame 231 to move toward the fixing mechanism 210, and pushes the concrete pipe into the interior of the conveying mechanism 220 through the top ring 232, so that the concrete pipe is placed above a set of bearing parts 225;
