Description

Technical Field

[0001] This utility model belongs to the field of shaft construction technology for vertical shaft tunneling machines, and relates to a water blocking and water collection structure for the shaft wall of a vertical shaft tunneling machine. Background Technology

[0002] During the construction of vertical shafts, especially deep shafts, water-rich strata are inevitably encountered due to the numerous geological formations traversed. Particularly when using shaft boring machines (TBMs), groundwater may seep from the shaft walls and flow into the excavation face. Simultaneously, construction wastewater generated during shaft lining, hoist cleaning, and equipment drainage can also flow into the excavation face along the shaft walls. All of these seepage conditions can worsen the working conditions at the excavation face and even lead to machine flooding accidents.

[0003] In existing technologies, water collection troughs are set at certain intervals on the shaft wall to prevent seepage water from flowing into the excavation face. This method not only increases the workload of shaft construction, but more importantly, the water collection troughs cannot move synchronously with the shaft tunneling machine, making it difficult to prevent seepage water from the shaft wall in the main body area of ​​the shaft tunneling machine from flowing into the excavation face. As the shaft tunneling machine advances, multiple water collection wells need to be set up inside the shaft, further increasing the workload of shaft construction. Utility Model Content

[0004] The purpose of this invention is to provide a water-blocking and water-collecting structure for the shaft wall of a vertical shaft tunneling machine, which solves the problem of increased well construction workload caused by setting up a water collection trough to block seepage in the prior art.

[0005] The technical solution adopted in this utility model is a water blocking and water collection structure for a vertical shaft tunneling machine, including a tunneling machine working platform. A sealing groove is opened on the side wall of the tunneling machine working platform, and a sealing airbag is fixedly connected in the sealing groove. An air supply component is set inside the tunneling machine working platform, and the air supply component is connected to the sealing airbag. A water collection component is set above the sealing groove on the side wall of the tunneling machine working platform.

[0006] The features of this utility model also include: The sealing groove and sealing airbag surround the entire side wall of the tunneling machine's working platform, and multiple air supply components are installed inside the tunneling machine's working platform to supply air to the sealing airbag.

[0007] The connection between the sealing groove and the side wall of the tunneling machine's working platform is chamfered.

[0008] The sealing airbag includes a main airbag and an air nozzle. The air nozzle is fixed inside the main airbag and passes through the inner wall of the main airbag and the sealing groove, thus fixing the main airbag inside the sealing groove. Multiple air nozzles are fixed inside the main airbag, and each air nozzle corresponds to an air supply component.

[0009] The air supply assembly includes an air supply valve connected to the sealing airbag. An exhaust valve is connected to the pipe connecting the sealing airbag and the air supply valve via a branch pipe. One-way valves are fixedly connected to the pipes connecting the exhaust valve and the air supply valve to the sealing airbag, respectively. The flow direction of the one-way valve corresponding to the air supply valve is from the air supply valve to the sealing airbag, and the flow direction of the one-way valve corresponding to the exhaust valve is from the sealing airbag to the exhaust valve.

[0010] The tunneling machine's working platform is fixedly connected to an air supply and exhaust distribution plate. The air supply and exhaust distribution plate is connected to the air supply valve and exhaust valve in each air supply component through pipes. An air compressor supply pipeline and a vacuum exhaust pipeline are opened on one side of the air supply and exhaust distribution plate.

[0011] The water collection assembly includes a water collection chamber fixedly connected inside the tunneling machine's working platform, and the water collection chamber is located above the sealing groove. Several water inlets are provided between the water collection chamber and the side wall of the tunneling machine's working platform. The water inlets are distributed around the side wall of the tunneling machine's working platform and are located on the same plane. Several drainage valves are fixedly connected to the bottom surface of the water collection chamber.

[0012] The water inlet is located on the side wall of the tunneling machine's working platform, near the sealing groove, and at a high position on the side wall of the water collection chamber.

[0013] The water collection tank has a sloping bottom that slopes from the water inlet to the drain valve.

[0014] The water collection chamber extends into the sealing groove inside the working platform of the tunneling machine.

[0015] The beneficial effects of this utility model are: This application installs a water-blocking and water-collecting structure on the side wall of the tunneling machine's working platform. By inflating a sealed airbag, it fills the gap between the tunneling machine's working platform side wall and the shaft wall, preventing seepage and downward flow. Furthermore, because this structure is installed on the side wall of the tunneling machine's working platform, its position can be adjusted as the tunneling machine moves during shaft excavation, eliminating the need for repeated excavation of a water collection trench and reducing the workload of shaft construction.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0019] Example 1: like Figure 1 As shown, the tunneling machine includes a tunneling machine working platform 1. A sealing groove 2 is provided on the side wall of the tunneling machine working platform 1. A sealing airbag 3 is fixedly connected in the sealing groove 2. An air supply component 4 is provided inside the tunneling machine working platform 1. The air supply component 4 is connected to the sealing airbag 3. A water collection component 5 is provided on the side wall of the tunneling machine working platform 1 above the sealing groove 2.

[0020] During shaft mining, when water seepage is detected in the shaft wall, high-pressure air can be introduced into the sealing airbag 3 via the air supply component 4. This causes the sealing airbag 3 to expand and fill the gap between the tunneling machine working platform 1 and the shaft wall, blocking any protruding water in the groove formed by the side wall of the tunneling machine working platform 1, the shaft wall, and the sealing airbag 3, preventing the seepage water from flowing towards the mining face. Simultaneously, the water collection component 5 can transfer the seepage water into the tunneling machine working platform 1 for storage, preventing the sealing airbag 3 from being in a constantly expanded state and rubbing against the shaft wall, which would reduce its service life.

[0021] Example 2 like Figure 1 As shown, the tunneling machine includes a tunneling machine working platform 1. A sealing groove 2 is provided on the side wall of the tunneling machine working platform 1. A sealing airbag 3 is fixedly connected in the sealing groove 2. An air supply component 4 is provided inside the tunneling machine working platform 1. The air supply component 4 is connected to the sealing airbag 3. A water collection component 5 is provided on the side wall of the tunneling machine working platform 1 above the sealing groove 2.

[0022] The sealing groove 2 and the sealing airbag 3 surround the side wall of the tunneling machine working platform 1. Multiple air supply components 4 are installed inside the tunneling machine working platform 1 to supply air to the sealing airbag 3. Multiple air nozzles 7 are fixed inside the main airbag 6, and each air nozzle 7 corresponds to one air supply component 4.

[0023] To ensure that the sealing airbag 3 can completely fill the gap between the side wall of the tunneling machine's working platform 1 and the shaft wall, an annular sealing airbag 3 is fitted into the sealing groove 2 on the side wall of the tunneling machine's working platform 1. However, the excessively large volume of the sealing airbag 3 makes it difficult to expand quickly when blocking water. Therefore, this application sets up multiple air supply components 4 to supply air to the sealing airbag 3, so that it can expand quickly when blocking water and complete the sealing work.

[0024] Example 3: like Figure 1 As shown, the tunneling machine includes a tunneling machine working platform 1. A sealing groove 2 is provided on the side wall of the tunneling machine working platform 1. A sealing airbag 3 is fixedly connected in the sealing groove 2. An air supply component 4 is provided inside the tunneling machine working platform 1. The air supply component 4 is connected to the sealing airbag 3. A water collection component 5 is provided on the side wall of the tunneling machine working platform 1 above the sealing groove 2.

[0025] The sealing groove 2 and the sealing airbag 3 surround the entire side wall of the tunneling machine working platform 1. Multiple air supply components 4 are installed inside the tunneling machine working platform 1 to supply air to the sealing airbag 3.

[0026] A chamfer is provided at the connection between the sealing groove 2 and the side wall of the tunneling machine working platform 1.

[0027] During expansion, the sealing airbag 3 will inevitably come into contact with the connection between the sealing groove 2 and the side wall of the tunneling machine's working platform 1. If the connection is sharp, it may cause severe wear between the sealing airbag 3 and the connection, affecting the service life of the sealing airbag 3. Therefore, the connection between the sealing groove 2 and the side wall of the tunneling machine's working platform 1 is chamfered to ensure a smooth transition between the two surfaces and reduce wear on the sealing airbag 3. At the same time, the chamfer also allows the expanded sealing airbag 3 to fit tightly against the side wall of the tunneling machine's working platform 1, preventing water seepage to the excavation face.

[0028] Example 4: like Figure 1 and Figure 2 As shown, the tunneling machine includes a tunneling machine working platform 1. A sealing groove 2 is provided on the side wall of the tunneling machine working platform 1. A sealing airbag 3 is fixedly connected in the sealing groove 2. An air supply component 4 is provided inside the tunneling machine working platform 1. The air supply component 4 is connected to the sealing airbag 3. A water collection component 5 is provided on the side wall of the tunneling machine working platform 1 above the sealing groove 2.

[0029] The sealing groove 2 and the sealing airbag 3 surround the entire side wall of the tunneling machine working platform 1. Multiple air supply components 4 are installed inside the tunneling machine working platform 1 to supply air to the sealing airbag 3.

[0030] A chamfer is provided at the connection between the sealing groove 2 and the side wall of the tunneling machine working platform 1.

[0031] The sealing airbag 3 includes a main airbag 6 and an air nozzle 7. The air nozzle 7 is fixed inside the main airbag 6 and passes through the inner wall of the main airbag 6 and the sealing groove 2, fixing the main airbag 6 inside the sealing groove 2. Multiple air nozzles 7 are fixed inside the main airbag 6, and each air nozzle 7 corresponds to an air supply component 4.

[0032] The air nozzle 7 passes through the inner wall of the sealing groove 2 and connects to the air supply component 4. When the main airbag 6 needs to expand, it provides high-pressure air to the main airbag 6, so that the main airbag 6 expands quickly and avoids water leakage.

[0033] Example 5: like Figure 1 , Figure 2 and Figure 3 As shown, the tunneling machine includes a tunneling machine working platform 1. A sealing groove 2 is provided on the side wall of the tunneling machine working platform 1. A sealing airbag 3 is fixedly connected in the sealing groove 2. An air supply component 4 is provided inside the tunneling machine working platform 1. The air supply component 4 is connected to the sealing airbag 3. A water collection component 5 is provided on the side wall of the tunneling machine working platform 1 above the sealing groove 2.

[0034] The sealing groove 2 and the sealing airbag 3 surround the entire side wall of the tunneling machine working platform 1. Multiple air supply components 4 are installed inside the tunneling machine working platform 1 to supply air to the sealing airbag 3.

[0035] A chamfer is provided at the connection between the sealing groove 2 and the side wall of the tunneling machine working platform 1.

[0036] The sealing airbag 3 includes a main airbag 6 and an air nozzle 7. The air nozzle 7 is fixed inside the main airbag 6 and passes through the inner wall of the main airbag 6 and the sealing groove 2, fixing the main airbag 6 inside the sealing groove 2. Multiple air nozzles 7 are fixed inside the main airbag 6, and each air nozzle 7 corresponds to an air supply component 4.

[0037] The air supply assembly 4 includes an air supply valve 9 connected to the sealing airbag 3. An exhaust valve 10 is connected to the pipe connecting the sealing airbag 3 and the air supply valve 9 via a branch pipe. One-way valves 8 are fixedly connected to the pipes connecting the exhaust valve 10 and the air supply valve 9 to the sealing airbag 3, respectively. The flow direction of the one-way valve 8 corresponding to the air supply valve 9 is from the air supply valve 9 to the sealing airbag 3, and the flow direction of the one-way valve 8 corresponding to the exhaust valve 10 is from the sealing airbag 3 to the exhaust valve 10.

[0038] The tunneling machine working platform 1 is fixedly connected to an air supply and exhaust distribution plate 11. The air supply and exhaust distribution plate 11 is connected to the air supply valve 9 and exhaust valve 10 in each air supply component 4 through pipes. An air compressor air supply pipeline 12 and a vacuum exhaust pipeline 13 are opened on one side of the air supply and exhaust distribution plate 11.

[0039] When sealing is required to prevent water leakage, open the air supply valve 9, and the air compressor supply line 12 provides high-pressure gas to the sealing airbag 3, causing it to expand rapidly and preventing water leakage from entering the excavation face; after the water leakage treatment is completed, open the air supply valve 9, and discharge the high-pressure gas in the sealing airbag 3 through the vacuum exhaust line 13, so that the sealing airbag 3 returns to its collapsed state and avoids interfering with the operation of the shaft tunneling machine.

[0040] By setting up the one-way valve 8, the high-pressure gas can be kept in a single direction during exhaust or supply, thereby improving the supply and exhaust speed.

[0041] Example 6: like Figures 1-4 As shown, the tunneling machine includes a tunneling machine working platform 1. A sealing groove 2 is provided on the side wall of the tunneling machine working platform 1. A sealing airbag 3 is fixedly connected in the sealing groove 2. An air supply component 4 is provided inside the tunneling machine working platform 1. The air supply component 4 is connected to the sealing airbag 3. A water collection component 5 is provided on the side wall of the tunneling machine working platform 1 above the sealing groove 2.

[0042] The sealing groove 2 and the sealing airbag 3 surround the entire side wall of the tunneling machine working platform 1. Multiple air supply components 4 are installed inside the tunneling machine working platform 1 to supply air to the sealing airbag 3.

[0043] A chamfer is provided at the connection between the sealing groove 2 and the side wall of the tunneling machine working platform 1.

[0044] The sealing airbag 3 includes a main airbag 6 and an air nozzle 7. The air nozzle 7 is fixed inside the main airbag 6 and passes through the inner wall of the main airbag 6 and the sealing groove 2, fixing the main airbag 6 inside the sealing groove 2. Multiple air nozzles 7 are fixed inside the main airbag 6, and each air nozzle 7 corresponds to an air supply component 4.

[0045] The air supply assembly 4 includes an air supply valve 9 connected to the sealing airbag 3. An exhaust valve 10 is connected to the pipe connecting the sealing airbag 3 and the air supply valve 9 via a branch pipe. One-way valves 8 are fixedly connected to the pipes connecting the exhaust valve 10 and the air supply valve 9 to the sealing airbag 3, respectively. The flow direction of the one-way valve 8 corresponding to the air supply valve 9 is from the air supply valve 9 to the sealing airbag 3, and the flow direction of the one-way valve 8 corresponding to the exhaust valve 10 is from the sealing airbag 3 to the exhaust valve 10.

[0046] The water collection assembly 5 includes a water collection chamber 14 fixedly connected inside the tunneling machine working platform 1, and the water collection chamber 14 is located above the sealing groove 2. Several water inlets 15 are provided between the water collection chamber 14 and the side wall of the tunneling machine working platform 1. The water inlets 15 are distributed around the side wall of the tunneling machine working platform 1 and are located on the same plane. Several drainage valves 16 are fixedly connected to the bottom surface of the water collection chamber 14.

[0047] The water inlet 15 is located on the side wall of the working platform 1 of the tunneling machine, close to the sealing groove 2, and the water inlet 15 is located at a high position on the side wall of the water collection chamber 14.

[0048] The water collection tank 14 has a bottom slope 17 that slopes from the water inlet 15 to the drain valve 16.

[0049] When seepage is blocked between the sealing airbag 3, the shaft wall and the side wall of the tunneling machine working platform 1, the seepage can be transferred to the water collection chamber 14 through the water inlet 15 to avoid excessive seepage. The groove formed by the sealing airbag 3, the shaft wall and the side wall of the tunneling machine working platform 1 alone cannot store the seepage.

[0050] After the seepage problem in the vertical shaft wall is resolved, the seepage water accumulated in the water collection tank 14 can be drained through the drainage valve 16 to facilitate the next water collection operation.

[0051] The water inlet 15 is close to the sealing groove 2, which can transfer as much of the seepage water trapped in the blocking water into the water collection chamber 14 as possible, so as to avoid too much seepage water remaining above the sealing airbag 3 and deteriorating the working condition of the excavation face after entering the excavation face.

[0052] The inclined surface 17 of the bottom of the tank, which is tilted towards the drain valve 16, helps to drain all the water stored in the water collection tank 14 during the drainage process.

[0053] Workflow: First, install the water-blocking and water-collecting structure involved in this application in the working position, as shown in the installation position... Figure 5 As shown: During the shaft excavation process, when workers discover water seepage in the shaft, they first open the air supply valve 9 and close the exhaust valve 10. Then, high-pressure gas is supplied through the air compressor supply pipeline 12. After being distributed by the air supply and exhaust distribution plate 11, the high-pressure gas enters the sealing airbag 3 through different air supply valves 9, causing the sealing airbag 3 to expand evenly and fill the gap between the side wall of the tunneling machine working platform 1 and the shaft wall, thus preventing water seepage from flowing down.

[0054] The seepage water sealed in the groove formed by the sealing airbag 3, the shaft wall and the side wall of the tunneling machine working platform 1 is stored in the water collection chamber 14 through the water inlet 15 to prevent seepage water from entering the excavation face.

[0055] Once the seepage problem in the shaft wall is resolved, first open the drain valve 16 to discharge the seepage water stored in the water collection tank 14 to the designated location.

[0056] After all the seepage water has been drained, close the air supply valve 9 and open the exhaust valve 10 to discharge the high-pressure air in the sealed airbag 3 along the path from the exhaust valve 10, the air supply and exhaust distribution plate 11 to the vacuum exhaust pipe 13, so that the sealed airbag 3 returns to its deflated state.
