[0016] A use method of a red sandstone roadbed drainage device in a rainy area, comprising the following steps:

[0017] Step one, device installation: first, a drainage ditch is dug on the left side of the roadbed, a deep pit is dug in the flat area below the slope protection on the right side of the roadbed, and an inclined circular channel is dug at the same angle of a straight line to connect the two, then the deposition module is installed in the deep pit on the right side of the roadbed, the water inlet pipe is laid inside the circular channel, the water collection module and the sewer pipe are assembled and then hoisted, and the sewer pipe at the bottom is assembled with the water inlet pipe, the connection ends of the two are sealed, and the overall length and inclination angle of the sewer pipe and the water inlet pipe can be adjusted according to the actual construction condition;

[0018] Step two, butt joint reinforcement: through the water diversion module, the front channel block and the rear channel block close to the water collection module are butt jointed with the main body of the water collection module, the parts extending to both sides of the water diversion module are assembled with the front channel block and the rear channel block close to the water collection module after butt joint, the reinforcement nails are driven into the soil from both sides to complete the pre-buried work, and the left and right sides of the water collection module and the water diversion module are filled with cast concrete for reinforcement;

[0019] Step three, module installation, put the mud fan from the inside of the water collection module into the sewer, the mud fan is connected with the stirring motor through a transmission shaft, the transmission shaft passes through the wear-resistant bearing inside the middle of the balance module, the wear-resistant bearing is clamped by bolts and two ring clamps, forming a whole structure, then the filter plate is slidably installed on the inside of the water diversion module along the longitudinal strips on the left and right sides of the water collection tank, then the protection module is installed on the upper end of the water collection module, the contact end of the two is sealed, then the lifting module is installed above the filter plate, at the same time, the cutting module is installed at the front end of the lifting module, finally the photovoltaic panel is installed on the top of the protection module, the module installation is completed;

[0020] Step four, when starting work, the water flow in the drainage ditch on both sides of the roadbed can be drained through the water diversion module, the debris transported with the rainwater will also enter the left and right sides of the outer end of the water collection module with the water flow, the debris is blocked by the filter plate, the water flow enters the inside of the water collection module, when the debris is accumulated too much on both sides of the water collection module, the winding motor in the cutting module starts to work, the cutting plate is lowered along the inner and outer clamping grooves in the contact block, enters the water flow, and cuts the debris flowing along the water flow, then the lifting motor is set to drive the lifting crossbar to rotate, and then drive the lifting plate to rotate, so that the filter plate is lifted from the water during winding, the debris accumulated above is driven to run upward, and stops when it reaches the height of the water diversion module above, then the roadbed drainage maintenance personnel clean up, reduce the difficulty of roadbed drainage maintenance, after cleaning, reverse the lifting motor to lower the filter plate into the water, then lift the cutting plate to let the water flow continue to flow into the water collection module, and block the larger impurities;

[0021] Step five, the water flow into the water collection module has been filtered once, the larger impurities are blocked outside, and some smaller particle impurities will flow into the sedimentation module along the lower connected sewer, when the water flow containing small impurities enters the sewer, the stirring motor is set to work, driving the lower mud fan to rotate, since the mud fan is vertically layered with multiple groups, it can crush the small impurities in the water flow, and the small particle impurities after crushing will be washed into the sedimentation module with the water flow;

[0022] Step six, when the crushed particle impurities are injected into the sediment tank with the water flow from the water inlet pipe, the speed of the water flow will slow down, and the particle impurities will fall into the bottom of the sediment tank and accumulate under the action of self-settling during the slowing down of the water flow, and the excess injected water flow will be directly discharged from the sediment tank into the drainage ditch opened on the right side, and the particle impurities deposited in the sediment tank are photographed by the camera in the adjusting tank. Since the position of the contact end of the sediment tank and the adjusting tank is embedded with organic glass and special sealing treatment is carried out, the light transmission is ensured under the premise of ensuring the strength, the height of the accumulated particle impurities in the interior is understood and recorded in the background, and when the accumulated height reaches the preset threshold, the roadbed drainage maintenance personnel can open the desilting motor to drive the desilting pump below to start working to extract the accumulated particle impurities and discharge them through the desilting pipe.

[0023] Compared with the prior art, the present application has at least the following beneficial effects:

[0024] In the above scheme, the water collecting module and the water guiding module are arranged, and the drainage device body is installed at the lowest area of the roadbed both sides of the water intercepting ditch to form a whole drainage system. When working, the impurities carried by the water flow also enter the left and right sides of the outer end of the water collecting module along with the water flow. The impurities are blocked by the filter plate, and when the impurities are accumulated too much, the impurities carried along the water flow in the water guiding module are cut off by the cutting module. Then the lifting module is arranged to drive the filter plate to lift up from the water, lift the accumulated impurities, stop when the height of the accumulated impurities reaches the height of the water guiding module, and the roadbed drainage maintenance personnel can clean up the accumulated impurities, thereby reducing the probability of roadbed drainage blockage and maintenance difficulty.

[0025] When the water flow carrying small particle silt enters the water collecting module and is discharged downward along the drain pipe connected below the water collecting module, the stirring motor starts to work, drives the mud cutter fan shaft connected with the stirring motor transmission end to rotate, and the fan blades of the mud cutter fan beat and break the small particle silt in the water flow into smaller particles, which are transported downward along with the water flow and are not easy to accumulate in the drainage pipeline, thereby reducing the water flow conveying space and improving the drainage efficiency.

[0026] Through the setting of the deposition module, when the water flow carrying smaller particles enters the deposition tank, the flow area of the water flow suddenly increases, which will reduce the flow rate of the water flow. In the process of slowing down the water flow, the smaller particles of the internal sediment will settle in the deposition tank and accumulate at the bottom. The excess injected water flow will be directly discharged along the outlet pipe according to the overflow effect. The particles deposited in the deposition tank are photographed by the camera in the adjusting tank to record the height of the internal particle impurities. When the accumulation height reaches the preset threshold, the roadbed drainage maintenance personnel are notified to start the desilting motor to drive the desilting pump to work, and the accumulated particle impurities are extracted and discharged through the desilting pipe to avoid damage to the subsequent drainage facilities, environment or equipment caused by the sediment, and to ensure the long-term effective operation of the red sandstone roadbed drainage system.

Next, install the protective module on the top of the water collection module. Seal the contact ends of the two. Then, install the lifting module above the filter plate. At the same time, install the cutting module at the front end of the lifting module. Finally, install the photovoltaic panel on top of the protective module to complete the module installation. Step 4: At the start of operation, the water diversion module diverts water from the drainage ditches on both sides of the roadbed. Debris transported along with the rainwater also flows with the water into the left and right sides of the outer end of the water collection module. Filter plates block the debris, while the water flows through into the interior of the water collection module. When too much debris accumulates on both sides of the water collection module, the winding motor in the cutting module starts working, lowering the suspended cutting plate down through the inner and outer slots on the contact block into the water flow to cut off the debris flowing with the water. Then, the lifting motor drives the lifting crossbar to rotate, which in turn drives the hanging plate to rotate. During the winding process, the filter plate is lifted from the water and the debris accumulated on top is carried upwards. It stops when it reaches the same height as the water intake module. Then, the roadbed drainage maintenance personnel clean it up to reduce the maintenance difficulty of the roadbed drainage. After the cleaning is completed, the lifting motor is rotated in the opposite direction to lower the lifted filter plate into the water. Then, the cut plate is lifted to allow the water flow to carry the debris to the water collection module to block larger impurities. Step 5: The water entering the water collection module has undergone a filtration process to remove larger impurities. These larger impurities are blocked on the outside, while smaller particles flow into the sedimentation module through the drain pipe connected below. When the water containing fine impurities enters the drain pipe, the set stirring motor starts working, driving the mud-crushing blade fan below to rotate. Since the mud-crushing blade fan has multiple vertical steps, it can crush the small impurities in the water flow. After being crushed, the small particles are washed into the sedimentation module by the water flow. Step Six: When the crushed particulate impurities are injected into the sedimentation tank through the inlet pipe along with the water flow, the water flow slows down as it enters the tank. As the flow slows, the particulate impurities settle to the bottom of the tank. Excess water is discharged directly from the tank through the outlet pipe into the drainage ditch on the right. The particulate impurities deposited inside the tank are captured by a camera in the regulating tank. Because plexiglass is embedded at the contact point between the tank and the regulating tank, and a special sealing treatment ensures both strength and light transmission, the camera can record the height of the accumulated particulate impurities. Once the accumulation height reaches a preset threshold, the roadbed drainage maintenance personnel can turn on the sludge removal motor to drive the sludge removal pump below, extracting the accumulated particulate impurities and discharging them through the sludge removal pipe.
