Abstract

The present invention provides a tunnel water-stop assembly, which includes: a first water-stop device arranged at the end of a first embedded pipe; the first water-stop device includes a first stopper, the first stopper The part is made of flexible material, the first stopper includes a stopper shell, the stopper shell encloses the accommodation cavity, the side of the stopper shell close to the center of the entrance hole is provided with a through hole, and the stopper shell is far away from the entrance hole One side of the center is provided with a communication port; the feeding mechanism, the feeding mechanism includes a storage tank and a feeding pipe, the storage tank is used to place sealing grease, one end of the feeding pipe is connected with the storage tank, and the other end of the feeding pipe is connected with the communication port , the storage tank transports the sealing grease to the containing cavity through the feeding pipe, so that the sealing grease flows out through the through hole; the adjusting mechanism is connected with the feeding mechanism, and the adjusting mechanism is used to adjust the feeding amount of the feeding mechanism. The technical solution provided by the invention can solve the technical problem of poor water-stopping effect of the water-stopping assembly in the prior art.

Description

technical field [0001] The invention relates to the technical field of tunnel excavation, in particular to a tunnel water stop assembly. Background technique [0002] At present, the pipe jacking construction technology is a non-excavation construction method, through which the pipeline can be buried with little or no excavation. When the pipe jacking construction process is working, the jacking force generated by the pipe jacking machine is used to overcome the friction between the pipe and the surrounding soil, so as to push the pipe into the soil layer according to the designed slope and transport the earth away. With the work of the pipe jacking machine, the pipe will pass through the soil layer from the working well and enter the receiving well. [0003] In the prior art, in order to prevent the muddy water in the tunnel from flowing out from the opening during pipe jacking construction, a water-stop assembly is generally arranged at the entrance of the tunnel, but the...
