Description

Technical Field

[0001] The present invention relates to the field of tunnel drainage technology and tunnel drainage water-solid separation technology, and in particular to a detachable tunnel drainage water-solid separation and circulation system. Background Art

[0002] During tunnel operation, especially in areas with complex geological conditions such as mountainous areas, rainwater can carry impurities such as solid particles, lumps, fallen leaves, and dirt, which can clog drainage pipes and cause water accumulation in the tunnel. Furthermore, tunnel leakage can be highly destructive, leading to a decrease in tunnel structural stability, localized water gushing and spraying, concrete spalling and falling in the vault, aging, disconnection, and short circuits in the electrical system, and impacting the compressive uplift of the roadbed and track. Therefore, tunnel leakage is a widespread and emerging problem that poses a serious threat to tunnel operational safety and urgently needs to be addressed. Furthermore, there is currently no effective method for addressing tunnel drainage pipe blockage, and existing solutions are costly, time-consuming, and inefficient. Furthermore, there is no effective monitoring technology to prevent tunnel water accumulation. Existing tunnel drainage methods and technologies fail to meet tunnel drainage needs. When a tunnel drainage pipe becomes blocked, treatment is complex, and there is no way to predict whether the current drainage volume will cause seepage and other hazards in the tunnel. Therefore, proactive water-solid separation in the tunnel is crucial. Summary of the Invention

[0003] The present invention aims to solve the technical problems existing in the prior art. To this end, the present invention provides a detachable tunnel drainage water-solid separation and circulation system, which can not only effectively separate water and solids, but also use a flow rate monitoring device to monitor the water flow in the tunnel drainage pipe. The current and pressure generated are processed by the processor and then transmitted to the computer terminal for data analysis. The data can not only predict the probability of water flood disasters that may occur in the tunnel in the current period, but also show whether the tunnel drainage pipe is blocked so that it can be dealt with in advance.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] A detachable tunnel drainage water-solid separation and circulation system, comprising:

[0006] A central drain pipe, a detachable storage tank, a sedimentation tank, a water storage tank and a circulation pipe; a conduit on the side of the central drain pipe is connected to the detachable storage tank at a certain angle, and then a sedimentation tank and a water storage tank are successively arranged in the middle section of the central drain pipe along the direction of water flow. A detachable cover is provided in the sedimentation tank, and the water inlet of the circulation pipe is connected to one side of the water storage tank. The water outlet of the circulation pipe is connected to the connection between the central drain pipe and the detachable storage tank, and a bayonet is provided at the front end of the conduit of the central drain pipe.

[0007] A flow rate monitoring device is provided on one side of the central drain pipe at the connection with the detachable storage tank, and a top circular hole filter plate is provided on the top of the flow rate monitoring device to filter large solid particles;

[0008] A circular flange is set at the top of the detachable storage tank near the tank mouth, multiple movable buckles are set on the outside of the circular flange, and multiple hooks are set on the upper end of the circular flange. The movable buckles and the hooks are set crosswise; when it is necessary to connect the detachable storage tank with the central drain pipe, the hook is inserted into the annular slot, and then the movable buckle is connected to the buckle mouth.

[0009] A fixed rod and a spiral fan are provided in the flow rate monitoring device. A top circular hole filter plate is provided on the top of the flow rate monitoring device. A connecting groove is provided at the bottom of the top circular hole filter plate. The connecting groove is connected to one end of the fixed rod. An annular sleeve is provided at the center of the spiral fan. The annular sleeve is sleeved outside the fixed rod.

[0010] A bottom circular hole filter plate is provided at the bottom of the flow rate monitoring device; a current and pressure processor is provided below the bottom circular hole filter plate, and an annular sleeve is provided at the other end of the fixed rod, and the annular sleeve is fixedly connected to the current and pressure processor.

[0011] The flowing water drives the propeller fan to rotate and generate electric current. At the same time, the pressure brought by the water flow will squeeze the fixed rod and the annular sleeve set at its bottom to generate pressure. After being processed by the processor, the current and pressure are transmitted to the computer terminal via radio and Bluetooth for data analysis. The computer terminal data can be used to determine whether the current tunnel drainage pipe is blocked and to predict whether the current drainage volume may cause natural disasters.

[0012] The connection method between the central drain pipe and the removable storage tank is that a thin-walled circular tube is placed in the central drain pipe and fits tightly against the wall of the central drain pipe. The surface of the thin-walled circular tube is treated with anti-seepage material, which expands when exposed to water to increase the tightness of the connection. When the removable storage tank needs to be connected to the central drain pipe, the removable storage tank hook is first inserted into the annular groove of the central drain pipe, and then the movable buckle is connected to the bayonet.

[0013] The mouth of the detachable storage tank is equipped with a perforated one-way valve, which only allows water to enter and exit, preventing solid particles from entering and overflowing. At the same time, the perforated one-way valve has holes and a certain degree of elasticity, and is made of stainless steel material with a certain degree of flexibility.

[0014] A cover is installed on the top of the sedimentation tank to facilitate subsequent cleaning and equipment replacement. At least three filters are installed according to the direction of water flow. The number of filters can be adjusted according to actual needs and the size of the sedimentation tank. Each filter should be closer to the bottom of the sedimentation tank than the previous one. The filter material requirements are: choose a material with more pores, larger surface area, and stronger adsorption capacity, such as activated carbon, multi-layer plastic or polypropylene fiber.

[0015] The tracks have a certain degree of mobility and the surface has serrations to increase grip. The distance between the two movable tracks is smaller than the thickness of the filter edge so that the filter is subjected to sufficient pressure. A water buffer zone is set at the bottom to slow down the water flow, allowing it to have a longer sedimentation time and filtration time.

[0016] A water pump is installed in the water reservoir to pump part of the flowing water into the circulation pipe. At the same time, a water flow monitoring sensor is placed in the circulation pipe to transmit information to the water pump to control the pumping speed of the flowing water.

[0017] Compared with the prior art, the beneficial effects and advantages of the detachable tunnel drainage water-solid separation and circulation system of the present invention are:

[0018] 1. This invention eliminates the use of filter plates alone and incorporates perforated and non-perforated one-way valves and a flow rate monitoring device to achieve water-solid separation and prevent unpredictable water flow. Using filter plates alone can lead to dead branches and leaves clinging to their surfaces. Therefore, this invention reduces the use of filter plates and utilizes a circulating pipe to flush their surfaces with water circulated back from a pump. The one-way valve not only effectively prevents this but also prevents unpredictable water flow.

[0019] 2. Following the direction of water flow, the present invention separates water and large solids or particles through a flow rate monitoring device, stores them in a detachable storage tank, and monitors the current water flow. At the same time, the instantaneous current generated by the rotation of the propeller driven by the flowing water and the pressure generated by the impact of the water flow are processed by the processor and finally sent to the computer terminal, playing a role in predicting natural disasters in mountain tunnels.

[0020] 3. Water flows through the sedimentation tank, where it is filtered and soil and other substances are deposited. Finally, some of the water flows through the reservoir. This reservoir is designed to not only pump water to the circulation pipeline but also reduce drainage pressure in the drainage pipe. The water is pumped through the circulation pipeline to the outlet, flushing debris attached to the flow rate monitoring device into a removable storage tank. This reduces the accumulation of particles in the pipeline and minimizes the risk of blockage in the tunnel drainage pipe. BRIEF DESCRIPTION OF THE DRAWINGS
