Description

Technical field:

[0002] The invention relates to a movable continuous pumping and drainage device for reverse slope of a tunnel. Background technology:

[0004] With the rapid development of engineering construction in my country, underground tunnel excavation projects are increasing in number. During underground tunnel excavation, sudden water inrush disasters are common due to various unfavorable geological conditions. These inrushes can be large or small. For minor inrushes, small-scale drainage facilities on-site are sufficient to control the water flow, using cement grouting to seal the inrush. However, for major inrushes, the speed and volume of the inrush are so high that existing small-scale pumping and drainage equipment is insufficient to cope. The rising water level can flood the entire tunnel, making it impossible to drain the water in time. For the safety of on-site workers, emergency evacuations are necessary.

[0005] Therefore, a movable continuous pumping and drainage device for tunnel reverse slope is needed to quickly and effectively pump out sudden water from top to bottom. Summary of the invention:

[0007] The technical problem to be solved by the present invention is to provide a movable continuous pumping and drainage device for tunnel reverse slope, which can flexibly and efficiently complete the tunnel reverse slope pumping and drainage operation.

[0008] The above purpose is achieved as follows: it includes a submersible pump trolley, the submersible pump trolley includes a body, wheels are installed on the body through an axle, the front end of the submersible pump trolley is connected to a steering mechanism, the steering mechanism includes a steering plate, two steering wheels are installed on both sides of the steering plate through an axle, an upward extending guide plate is fixed in the middle of the steering plate, the cylinder bodies of the two cylinders that control the steering of the steering plate are fixed at the front end of the submersible pump trolley, the cylinder rods of the two cylinders are fixed on the steering plates on both sides of the guide plate, the rear end of the connecting plate is connected to the middle of the front end of the submersible pump trolley through a rotating shaft, and the front end of the connecting plate is connected to the middle of the rear end of the steering plate through bolts; when steering is required, the cylinder rod of a cylinder extends to drive the steering plate to rotate, thereby changing the direction of travel of the submersible pump trolley. After the steering is completed, the cylinder rod of the cylinder retracts.

[0009] The submersible pump is installed on a submersible pump trolley. The rear end of the submersible pump is connected to a drain pipe, which is welded to a number of drain pipe trolleys arranged in a front-to-back manner. The drain pipe trolley includes a frame, and the wheels are connected to the frame through an axle.

[0010] A drainage pipe transverse moving trolley is also provided under the drain pipe. The drainage pipe transverse moving trolley includes a base. The wheels are installed on both sides of the base through an axle. A jack is fixed at each end of the base. A drainage pipe is placed in a groove above the base. The upper ends of the two jacks are respectively fixed on both sides of the drainage pipe. The drain pipe is placed in the groove.

[0011] The drainage pipe trolley is located between the two drainage pipe trolleys and can move horizontally, while the drainage pipe trolley and submersible pump trolley can move forward and backward. When the drainage pipe trolley moves horizontally, the jack works to lift the drain pipe, causing the wheels of the drainage pipe trolley to be suspended in the air, eliminating friction, and manually pushing the drainage pipe trolley to achieve horizontal movement.

[0012] The advantages of the present invention are that the device can flexibly and efficiently complete the reverse slope pumping and drainage operation of the tunnel, the submersible pump is flexible to move underwater, the operation is simple, the cycle time of pumping and drainage is shortened, costs are saved, and the construction progress is accelerated.

[0020] The following combination Figure 1-4 The present invention is further described;

[0021] It includes a submersible pump trolley 1, which includes a body 11. Wheels are installed on the body through shafts. The front end of the submersible pump trolley is connected to a steering mechanism 2. The steering mechanism includes a steering plate 21. Two steering wheels 22 are installed on both sides of the steering plate through shafts. An upward extending guide plate 23 is fixed to the middle of the steering plate. The cylinder bodies of two cylinders 24 for controlling the steering of the steering plate are fixed to the front end of the submersible pump trolley. The cylinder rods of the two cylinders are fixed to the steering plates on both sides of the guide plate. The rear end of the connecting plate 25 is connected to the middle part of the front end of the submersible pump trolley through a rotating shaft. The front end of the connecting plate is connected to the middle part of the rear end of the steering plate through bolts. When steering is required, the cylinder rod of a cylinder extends to drive the steering plate to rotate, thereby changing the direction of travel of the submersible pump trolley. After the steering is completed, the cylinder rod of the cylinder retracts.

[0022] The submersible pump 3 is installed on the submersible pump trolley. The rear end of the submersible pump is connected to a drain pipe 4. The drain pipe is welded to a plurality of drain pipe trolleys 5 arranged in a front-to-back manner. The drain pipe trolley includes a frame 51, and the wheels are connected to the frame through an axle.

[0023] A drainage pipe transverse movement trolley 6 is also provided under the drain pipe. The drainage pipe transverse movement trolley includes a base 61. The wheels are installed on both sides of the base through the shaft. A jack 62 is fixed at each end of the base. A drainage pipe is placed in a groove 63 above the base. The upper ends of the two jacks are respectively fixed on both sides of the drainage pipe. The drain pipe is placed in the drainage pipe groove.

[0024] The drainage pipe trolley is located between the two drainage pipe trolleys and can move horizontally, while the drainage pipe trolley and submersible pump trolley can move forward and backward. When the drainage pipe trolley moves horizontally, the jack works to lift the drain pipe, causing the wheels of the drainage pipe trolley to be suspended in the air, eliminating friction, and manually pushing the drainage pipe trolley to achieve horizontal movement.

[0025] Reference Figure 5 The rear end of the drainage pipe is connected to the fixed drainage pipe 8 through a hose 7, and the water is discharged out of the cave through the fixed drainage pipe. The fixed drainage pipe is the fixed drainage pipe on the side wall of the tunnel branch hole. The fixed drainage pipe on the side wall is connected toward the water surface as the water level drops.

[0026] When draining water, two sets of this device can be set up. The first submersible pump and the second submersible pump are placed on the submersible pump trolley of one set of this device, and the third submersible pump and the fourth submersible pump are placed on the submersible pump trolley of the other set of this device. First, connect the power cords of the first submersible pump and the second submersible pump, and connect the rear end of the drain pipe to the fixed drain pipe through a hose. Then, use the gravity of the submersible pump and the drain pipe to manually push the submersible pump trolley and the drain pipe trolley to make the first submersible pump and the second submersible pump enter the water. In the process of the submersible pump moving into the water, if it is found that the direction of the submersible pump moving into the water changes, if adjustment is needed, the steering plate is driven by the cylinder to rotate to adjust the direction of the submersible pump. If the first submersible pump and the second submersible pump and the drain pipe are deviated, the position of the drain pipe is adjusted by using the drain pipe transverse trolley. While the first and second submersible pumps are pumping water underwater, the third and fourth submersible pumps are placed behind them. As the water level drops, the first and second submersible pumps leak out of the water, and the first and second submersible pumps are stopped from operating. The third and fourth submersible pumps are then pushed into the water. The third and fourth submersible pumps continue to pump water underwater. Once the third and fourth submersible pumps leak out of the water, the third and fourth pumps are stopped from operating, and the first and second submersible pumps are pushed into the water again. This process repeats. The movement of the submersible pumps and drainage pipes is accomplished entirely by the trolleys, similar to how a person walks. The drainage system moves forward step by step through the water.
