Embodiment 1

[0027] Such as figure 2 As shown, the drainage pipe system includes an expansion part and a seepage part, wherein the expansion part includes at least one section of pipe body I1 made of seamless steel pipe, and the outside of the pipe body I1 is wrapped with an annular hollow inflatable air bag 4. The main ventilation pipe 2 made of seam steel pipe is placed in the pipe body I1, and the main ventilation pipe 2 is provided with ventilation holes 3 equal in number to the annular hollow inflatable airbag 4, and the annular hollow inflatable airbag 4 The ventilation pipe 5 communicates with the ventilation hole 3 of the main ventilation pipe 2 through the pipe body I1, and the water seepage part includes at least one pipe body II6 made of seamless steel pipe, and the pipe body I1 is separated from the pipe body II6 It is set and communicated, and at least one drain hole 7 is set on the pipe body II6, and one end of the drain pipe is inserted into the surrounding rock for sealing...

Embodiment 2

[0030] Such as figure 2 As shown, on the basis of Example 1, blocking gaskets 8 are provided on both sides of the annular hollow inflatable airbag 2, and the blocking gasket 8 effectively limits the longitudinal deformation of the annular hollow inflatable airbag 2, and enhances the airbag's impact on the surrounding area. The radial extrusion of the rock is more conducive to the rapid fixation of the drainpipe.

Embodiment 3

[0032] Such as figure 2 As shown, on the basis of Example 1, the pipe body II6 is wrapped with non-woven fabric 9, and the non-woven fabric 9 provides a good drainage channel for the seepage of surrounding rock, so that the drainage pipe can drain water more effectively.

Abstract

The invention discloses a cooling circulation system for a single-arm three-dimensional measurement liner, which includes an expansion part and a water seepage part, wherein the expansion part includes at least one section of pipe body I (1), wrapped in the pipe body I (1 ), the external annular hollow air bag (4), the main ventilation pipe (2) placed in the pipe body I (1), the water seepage part includes at least one section of the pipe body II (6), and the pipe body I (1 ) and the pipe body II (6) are arranged at intervals and communicate with each other, and at least one drain hole (7) is arranged on the pipe body II (6), and one end of the drainage pipe is inserted into the surrounding rock for sealing. By inflating the air bag, the drainage pipe can be quickly fixed in the surrounding rock, so that the surrounding rock can be drained intensively. When drainage is not needed, the air bag is deflated and contracted, and the drain pipe can be taken out for repeated use.

Description

technical field [0001] The invention relates to the field of drainage pipes for tunnel construction, in particular to a cooling circulation system for a single-arm three-dimensional measuring liner. Background technique [0002] In the construction of highways, railways, subways and other projects, tunnel excavation is an inevitable and extremely important part, and drainage in tunnels is also very important. Once water leakage occurs, it will not only affect the construction, but also easily cause safety accidents. Traditional tunnel drainage mostly lays cement drainage pipes in the surrounding rock, which is prone to water leakage and is not safe. Chinese patent CN202946194U discloses a figure 1 The drainage pipe system shown is an improvement on the traditional cement drainage pipe, and its technical solution is: a cooling circulation system for a single-arm three-dimensional measurement liner, including a cement pipe 01 with a circular cross-section. The outer wall of ...
