Description

Technical Field

[0001] The utility model relates to the technical field of pipe jacking construction, in particular to an opening template and a template system for water-stopping and sealing doors. Background Art

[0002] Pipe jacking construction is a trenchless construction method and a pipeline burial construction technology that requires no excavation or less excavation. Pipe jacking construction 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, jack the pipeline into the soil according to the designed slope, and transport the soil away. After one section of the pipeline is pushed into the soil layer, the second section of the pipeline will continue to be pushed in. The principle is to use the thrust of the pipe jacking machine to push the pipe jacking machine from the starting pit through the soil layer and lift it into the receiving pit. The pipeline follows the pipe jacking machine and is buried between the starting pit and the receiving pit.

[0003] The construction of pipe jacking adopts earth pressure balance and mud water balance pipe jacking machine. It is necessary to set a water-stop sealing door at the tunnel entrance of the starting pit to prevent the leakage of mud during the jacking process of the pipe jacking machine and affect the water pressure of the cutting surface. The conventional traditional construction method uses small pieces of wooden templates to splice the hole template of the water-stop sealing door. This method requires multiple assembly of wooden templates in the manner of building blocks, which is not only time-consuming and labor-intensive, but also has poor integrity of template reinforcement, low safety factor, and inconvenient disassembly.
