Embodiment 1

[0028] Embodiment 1, a kind of gushing water blocking device, such as image 3 , 4 As shown, it includes a water stop rod 1 made of seamless steel pipe, and uses the water stop rod 1 to block the water gushing hole. Such as figure 1 , 2 As shown, the water stop rod 1 is connected with an oil cylinder 2, and the oil cylinder 2 is connected with the rotating part of the rock bolter 3, and the oil cylinder 2 is connected with the hydraulic pump station 5 through the control valve group 4. The rotation of the bolter 3 can drive the oil cylinder 2 to rotate in the tunnel, and can drive the oil cylinder 2 to any position that needs to be blocked for construction. The extension of the oil cylinder 2 can drive the water stop rod 1 to insert into the water gushing hole to realize the water gushing hole automatic blocking.

[0029] Further, the oil cylinder 2 is hinged on the rotating part of the rock bolt 3 through the hinge seat 23, the hinge seat 23 is a universal ball joint seat...

Embodiment 2

[0034] Embodiment 2, a control method of a water gushing sealing device, comprising the following steps:

[0035] ① Control the rotation of the bolter 3 until the water stop rod 1 reaches the water gushing hole;

[0036] ② Control the extension of the oil cylinder 2 until the oil cylinder 2 drives the water stop rod 1 to insert into the water gushing hole to ensure that the arc-shaped sealing plate 13 fits with the wall surface at the front end of the water gushing hole;

[0037] ③ If the water gushing is effectively controlled, use expansion bolts to fix the arc-shaped sealing plate 13 on the wall;

[0038] ④ If the water gushing is not under control, control the high-pressure grouting system to perform double-liquid grouting into the water stop rod 1, and use expansion bolts to fix the arc-shaped sealing plate 13 on the wall;

[0039] ⑤Remove the connection between the water stop rod 1 and the oil cylinder 2, and remove the oil cylinder 2 from the rock bolter 3.

Abstract

The invention discloses a water gushing sealing device and a control method thereof, which solves the technical problem that the water gushing cannot be blocked efficiently and conveniently during tunnel excavation. The invention includes a water stop rod, and the water gushing hole is blocked by using the water stop rod. The water stop rod is connected with an oil cylinder, and the oil cylinder is connected on the rotating part of the rock bolter, and the oil cylinder is connected with the hydraulic pump station through the control valve group. The rotation of the rock bolter can drive the oil cylinder to rotate in the tunnel, and can drive the oil cylinder to any position that needs to be blocked for construction. The extension of the oil cylinder can drive the water stop rod to insert into the water gushing hole, so as to realize the automatic sealing of the water gushing hole. The plugging structure of the present invention can not only reliably plug water gushing holes of different sizes, but also realize automatic control, avoiding a series of adverse effects caused by manual operation.

Description

technical field [0001] The invention belongs to the technical field of water gushing control, in particular to a water gushing blocking device and a control method thereof. Background technique [0002] With the rapid development of domestic mountain tunnels, more and more TBMs are used for tunnel construction, and it has quickly become the development trend of mountain tunnel construction. During the construction process, when there is a sudden water gushing in a tunnel with developed groundwater, it will not only cause a large amount of groundwater loss and damage to the environment, but also the tunnel will be flooded and cannot continue to be excavated, causing extremely serious adverse effects on the tunnel construction. [0003] After retrieval, the existing patent application for invention with the application date of 2018.04.02 and the application number of 201810281946.8 discloses a tunnel drilling water gushing blocking device and method. The tunnel drilling water ...
