Embodiment 1

[0020] A jacking pipe that is tightly butted and has an escape pipe, which is formed by connecting more than two jacking pipes, and two or more protruding teeth 9 arranged at intervals are respectively arranged on the two ends of the jacking pipe, connecting two The jacking pipes are meshed and docked by convex teeth 9. An escape pipe 1 is installed on the inner pipe wall of the jacking pipe. The two ends of the escape pipe 1 are provided with corrugated joints 2. The corrugated joints 2 of the adjacent escape pipe 1 pass through the connecting ring 3. interconnected.

[0021] During on-site construction, it is necessary to dock the pipe jacking of the latter section with the pipe jacking of the previous section, install the escape pipe 1 on the inner pipe wall of the pipe jacking, and the two sections of pipe jacking can quickly complete the docking through the convex teeth 9, and Due to the position limitation of the protruding teeth 9, the escape pipe 1 can also be docked q...

Abstract

The invention relates to pipe jacking, in particular to a pipe jacking which is tightly butted and has an escape pipe. A jacking pipe tightly butted with an escape pipe, which is formed by connecting more than two jacking pipes, and two or more protruding teeth (9) arranged at intervals are respectively arranged on the two ends of the jacking pipe, and are connected to each other. The two jacking pipes are meshed and docked by convex teeth (9). An escape pipe (1) is installed on the inner pipe wall of the jacking pipe. The two ends of the escape pipe (1) are provided with corrugated joints (2). The corrugated sections (2) of the pipe (1) are connected to each other by connecting rings (3). The invention installs an escape pipe inside the pipe jacking, which is convenient for people to escape from the pipe jacking, and can quickly complete the butt joint between the pipe jacking and the escape pipe (1).

Description

technical field [0001] The invention relates to pipe jacking, in particular to a pipe jacking which is tightly butted and has an escape pipe. Background technique [0002] Pipe jacking construction is a non-excavation construction method, and it is a pipeline burying construction technology that does not excavate or excavates less. 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, push the pipeline into the soil according to the designed slope, and transport the earth away. In the long-distance pipe jacking construction, workers need to enter the front end of the pipe jacking for survey and maintenance, so the safety of the workers needs to be guaranteed. During on-site construction, how to complete the quick docking of the jacking pipe and the escape pipe has become a difficult problem. Contents of the invention [0003] The object of the pre...
