[0002] Tunnel civil construction refers to the construction of underground tunnel projects. During the underground civil construction, a large number of drainage devices are needed to discharge the industrial wastewater generated during the tunnel civil construction to prevent the wastewater from accumulating and soaking the land around the tunnel, making it soft, and avoiding the problem of unstable land around the tunnel in the later stage.

[0003] At present, the existing drainage devices are unable to filter a large amount of sediment in the water during drainage. The sediment will follow the water flow into the interior of the drainage device, causing blockage inside the drainage device, making it impossible to perform normal drainage work. The drainage device needs to be subsequently repaired, which will cause some inconveniences.

[0004] Therefore, those skilled in the art provide a drainage device for tunnel civil construction that can avoid blockage, so as to solve the problems raised in the above background technology. Utility Model Content

[0023] The anti-blocking mechanism 2 includes a first loading box 202, the inner wall of which is fixedly connected to two filter screens 201, the inner top wall of the first loading box 202 is fixedly connected to a telescopic rod 203, the telescopic end of the telescopic rod 203 is fixedly connected to a block 204, the right side of the first loading box 202 is fixedly connected to a second loading box 205, the front of the second loading box 205 and the back of the second loading box 205 are fixedly connected to a floating plate 206, the right side of the first loading box 202 is fixedly connected to two fixed blocks 210, the inner walls of the two fixed blocks 210 are commonly fixedly connected to an air pump 209, the input end of the air pump 209 is fixedly connected to an air extraction pipe 208, the bottom end of the air extraction pipe 208 passes through the second loading box 205 and extends to the bottom of the second loading box 205, the output end of the air extraction pump 209 is fixedly connected to an air outlet pipe 207, the left end of the air outlet pipe 207 passes through the first loading box 202 and extends to the inside of the first loading box 202.

[0024] Specifically, a fixing seat 6 is fixedly connected to the upper surface of the rectangular box 1 , and a water pump 5 is fixedly connected to the inner wall of the fixing seat 6 .

[0025] Through the above technical solution, by providing the fixing base 6 and the water pump 5, the water pump 5 can be fixed by the fixing base 6, thereby making the operation of the water pump 5 more stable.

[0026] Specifically, the output end of the water pump 5 is fixedly connected to the water outlet pipe 4 , and the bottom end of the water outlet pipe 4 passes through the rectangular box 1 and extends to the interior of the rectangular box 1 .

[0027] Through the above technical solution, by providing the water outlet pipe 4, the water source pumped out by the water pump 5 through the water outlet pipe 4 can be drained out, thereby achieving a better auxiliary effect.

[0028] Specifically, the input end of the water pump 5 is fixedly connected to a water pumping pipe 7 , and the top end of the water pumping pipe 7 is fixedly connected to the bottom surface of the first loading box 202 .

[0029] Through the above technical solution, by providing the water pumping pipe 7, it is possible to contact the substance produced by the operation of the water pump 5 to draw water into the interior of the water pumping pipe 7, thereby facilitating the discharge of the water.

[0030] Specifically, a fixing plate 10 is fixedly connected to the right side surface of the rectangular box 1 , and the interior of the fixing plate 10 is clamped with the outer surface of the water pumping pipe 7 .

[0031] Through the above technical solution, by providing the fixing plate 10, the water pumping pipe 7 can be clamped and fixed by the fixing plate 10, and then the water pumping pipe 7 and the first loading box 202 connected to the top end thereof can be placed.

[0032] Specifically, the front surface of the rectangular box 1 is fixedly connected with a drainage pipe 8 , the bottom surface of the rectangular box 1 is fixedly connected with two sets of universal wheels 9 , and the left side surface of the rectangular box 1 is fixedly connected with a push handle 3 .

[0033] Through the above technical solution, by providing a drain pipe 8, a universal wheel 9 and a push handle 3, the water inside the rectangular box 1 can be discharged, and the universal wheel 9 can drive the device to move, reducing the resistance generated during movement, and the push handle 3 makes it convenient to apply thrust to the device.

[0034] The working principle of the utility model is as follows: when in use, the universal wheel 9 can be used to push the device into the interior of the tunnel body 11, and then a power supply system adapted thereto is built at a specific location, and then the water pump 7 is removed from the fixing plate 10, and then the first loading box 202 is placed in the drainage channel 12. When we need to change the position of the device, the original method is to move it with some transportation equipment, but now it only needs to be pushed by manpower to move the device, avoiding the tedious deployment of various mobile equipment, and then the air pump 209, the water pump 5 and the telescopic rod 203 are connected to the drainage channel 12. The power supply is turned on. When the power supply is turned on, the device can be used normally. Since one side of the first loading box 202 is connected to the input end of the water pumping pipe 7, the maximum distance between the first loading box 202 and the rectangular box 1 is determined by the water pumping pipe 7. Then, the length of the water pumping pipe 7 can be appropriately increased according to the distance between the device and the accumulated water. Due to the effect of the floating plate 206, the second loading box 205 will float on the water surface, while the second loading box 205 will sink into the water. Then, the water pump 5 is controlled to operate, and the water pump 5 can be used to drive the water pumping pipe 7 to extract water through the first loading box 202. The water pumping pipe 7 is connected to the first loading box 202. The water flow rate that the first loading box 202 can carry can be constructed in advance according to the water flow of different flow rates, so as to ensure that when facing a large flow of tunnel water, the device can still effectively filter the tunnel water, and then the water source passes through the filter 201 into the first loading box 202 and enters the water pumping pipe 7, so the silt will be intercepted outside by the filter 201. When there is too much silt, causing the filter holes inside the filter 201 to be blocked, the first loading box 202 is first placed in the clean water, and then the telescopic rod 203 is controlled to push the block 204 to connect the first loading box 202 with the water pumping pipe 7. The filter screen 201 of the first loading box 202 is blocked by the block, and then the vacuum pump 209 is controlled to operate. The vacuum pump 209 drives the vacuum pipe 208 to draw outside air into the first loading box 202. The excessive gas inside the first loading box 202 can only be discharged to the outside through the filter screens 201 on both sides, thereby pushing the silt accumulated inside the filter screen 201 outward. In addition, the silt is moistened by water to make it soft, which can greatly reduce the difficulty of discharging the silt, solve the problem of silt clogging the filter screen 201, and effectively avoid the problem of silt clogging when the device is in use, resulting in poor drainage effect.

[0035] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
