Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and specifically to a device for quickly sealing water inrush in underground structures. Background Technology

[0002] With the advancement of technology, underground space has developed rapidly, and the overall utilization rate of urban underground space in China is currently about 33%. This rapid development has also brought various safety risks, such as water inrush in the retaining structure during subway station construction, grouting eruptions from tunnel segments during shield tunneling, and water inrushes caused by external exploration boreholes penetrating tunnel segments during tunnel operation. These risks seriously threaten the personal safety and property of urban residents. When an emergency occurs, it is crucial to control it as quickly as possible, especially when water suddenly erupts from underground structures. Currently, the commonly used method for controlling such emergencies is to seal and divert the water before grouting.

[0003] Current rapid water inrush sealing devices for tunnel structures are mainly designed for shield tunnel segments and deep foundation pit retaining structures, with the sealing location at the defect site in either the segment or the retaining structure. The primary construction method involves welding steel plates to the water inrush location for sealing and diversion. However, under conditions of large water inrushes, this requires highly skilled welders. Furthermore, if gaps appear at the welded location after welding, water may overflow from these gaps, necessitating additional welding. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects of the prior art and provide a device for quickly sealing water inrush in underground structures. In use, a fixing plate is fixed to the wall of the underground structure. By inflating the annular airbag, the gap between the fixing plate and the wall is sealed to prevent water from overflowing from between the fixing plate and the wall. Finally, the ball valve is closed to seal the water inrush location.

[0006] A fixing plate having a connecting hole that connects two sides of the fixing plate;

[0007] A connecting pipe is fixedly installed in the connecting hole, and a portion of the connecting pipe extends outside the fixed plate to form an installation section;

[0008] A ball valve installed in the mounting section; and

[0009] An annular airbag is fixed to the side of the fixing plate away from the ball valve. The annular airbag surrounds the connecting hole and has an inflation nozzle. The connecting pipe is aligned with the water inflow position, and the fixing plate is fixed to the underground structure. The gap between the underground structure and the fixing plate is sealed by inflating the annular airbag, and the ball valve is closed to block the water inflow position.

[0010] Furthermore, a switch handle is provided on the top of the ball valve, and the switch handle controls the opening or closing of the ball valve.

[0011] Furthermore, the fixing plate has an inflation port corresponding to the inflation nozzle, and the inflation nozzle is disposed inside the inflation port.

[0012] Furthermore, the fixing plate is made of rubber.

[0015] Furthermore, the mounting holes are spaced apart along the edge of the fixing plate.

[0016] Furthermore, the inner diameter of the annular airbag is larger than the diameter of the connecting hole.

[0017] Compared with the prior art, this utility model has the following advantages:

[0018] In use, the fixing plate is fixed to the wall of the underground structure with expansion bolts, the annular airbag is inflated to seal the gap between the fixing plate and the wall to prevent water from overflowing from between the fixing plate and the wall, and finally the ball valve is closed to seal the water inrush point.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] See Figure 1 A device for quickly sealing water inrush in underground structures includes: a fixed plate 6, a connecting pipe, a ball valve 4, and an annular airbag 3. The fixed plate 6 has a connecting hole connecting two sides of the fixed plate 6; the connecting pipe is fixedly disposed in the connecting hole, and a portion of the connecting pipe extends outside the fixed plate 6 to form an installation section; the ball valve 4 is disposed in the installation section; and the annular airbag 3 is fixed to the side of the fixed plate 6 away from the ball valve 4, the annular airbag 3 surrounds the connecting hole, and an inflation nozzle 2 is formed on the annular airbag 3. The connecting pipe is aligned with the water inrush position, and the fixed plate 6 is fixed to the underground structure. By inflating the annular airbag 3 to seal the gap between the underground structure and the fixed plate 6, the ball valve 4 is closed to seal the water inrush position.

[0024] In this utility model, a preferred embodiment is as follows: When water seepage occurs, the fixing plate 6 is provided, and the connecting hole of the fixing plate 6 is aligned with the center of the water seepage location. Preferably, the size of the annular airbag 3 and the fixing plate 6 is larger than the size of the water seepage location. The valve is opened to facilitate the subsequent installation of the fixing plate 6, allowing water to flow out from the connecting pipe location, thereby reducing the water outflow and water pressure on the side of the fixing plate 6, making it easier for construction personnel to fix the fixing plate 6 to the wall 1 of the underground structure. After fixing the fixing plate 6 to the wall 1 of the underground structure, an inflation device is provided to inflate the annular airbag 3, thereby sealing the gap between the fixing plate 6 and the wall 1. When there is no more water overflowing between the fixing plate 6 and the wall 1, the ball valve 4 is closed, thereby sealing the water seepage area 5.

[0025] Furthermore, a switch handle is provided on the top of the ball valve 4, which controls the opening or closing of the ball valve 4. This switch handle allows for convenient operation by construction personnel.

[0026] Furthermore, the fixing plate 6 has an inflation port corresponding to the inflation nozzle 2, and the inflation nozzle 2 is disposed in the inflation port.

[0027] Furthermore, the fixing plate 6 is made of rubber. The rubber fixing plate 6 effectively reduces the overall weight of the fixing plate 6, thus facilitating handling by construction personnel.

[0028] Furthermore, the fixing plate 6 is fixed to the underground structure by expansion bolts 7. In use, several fixing holes can be drilled on the wall 1 at the water inflow location, corresponding to the positions of the expansion bolts 7 on the fixing plate 6, and the expansion bolts 7 on the fixing plate 6 can be driven into the fixing holes to fix the fixing plate 6 to the wall 1 of the underground structure.

[0029] Furthermore, the fixing plate 6 has mounting holes corresponding to the expansion bolts 7, and the expansion bolts 7 are inserted into the mounting holes.

[0030] Furthermore, the mounting holes are spaced apart along the edge of the fixing plate 6.

[0031] Furthermore, the inner diameter of the annular airbag 3 is larger than the diameter of the connecting hole.

[0032] The following describes the usage process of the device for rapid sealing of water inrush in underground structures according to this utility model.

[0033] When water seepage occurs, the fixing plate 6 is provided, and the connecting hole of the fixing plate 6 is aligned with the center of the water seepage location. Preferably, the size of the annular airbag 3 and the fixing plate 6 is larger than the size of the water seepage location. The valve is opened to facilitate the subsequent installation of the fixing plate 6, allowing water to flow out from the connecting pipe location, thereby reducing the water outflow and water pressure on the side of the fixing plate 6, making it easier for construction personnel to fix the fixing plate 6 to the wall 1 of the underground structure. The fixing plate 6 is fixed to the wall 1 of the underground structure using expansion bolts 7. An inflation device is provided to inflate the annular airbag 3, thereby sealing the gap between the fixing plate 6 and the wall 1. When there is no more water overflowing between the fixing plate 6 and the wall 1, the ball valve 4 is closed, thereby sealing the water seepage area 5.
