Description

Technical Field

[0001] The present invention relates to the technical field of tunnel drainage and flood prevention, and particularly to an intelligent integrated system for drainage and flood prevention of urban rail transit interval tunnels. Background Art

[0002] With the acceleration of the urbanization process, rail transit, as an efficient and convenient urban public transportation mode, has become increasingly important. Interval tunnels, as a key component of rail transit, play an important role in train operation. However, due to the fact that interval tunnels are usually underground and are affected by various factors such as geological conditions, climate factors, and urban construction, they face severe drainage and flood prevention problems. The traditional drainage systems for urban rail transit interval tunnels mostly adopt a combination of simple drainage ditches, sump wells, and drainage pumps. Such systems can play a certain role in dealing with regular precipitation and a small amount of seepage water. However, in the face of extreme weather conditions such as heavy rain and extremely heavy rain, their limitations are fully exposed. Therefore, an intelligent integrated system is needed to enhance the tunnel drainage and flood prevention capabilities.

[0003] Traditional tunnel drainage equipment mainly relies on drainage ditches to carry out the external drainage operation of tunnel water accumulation. However, in the face of sudden situations such as extreme rainfall, a large amount of rainwater rushes in within a short period of time. Limited by its own drainage capacity, the traditional drainage system is unable to drain the accumulated water in a timely and efficient manner, resulting in a sharp rise in the water level in the tunnel. At the same time, the traditional system lacks a complete real-time water level monitoring and drainage equipment operation status monitoring mechanism. It is difficult for staff to obtain accurate and detailed dynamic information about the water level in the tunnel and the operation parameters of the drainage equipment in the first time, which greatly hinders the timely, accurate judgment and effective disposal of the drainage situation and poses a huge hidden danger to the safe operation of the tunnel. Summary of the Invention

[0004] The present invention relates to an intelligent integrated system for drainage and flood prevention of urban rail transit interval tunnels, which has a water retaining plate and a water level sensor. A lower drainage channel is opened at the bottom of the tunnel main body, which can effectively collect the accumulated water in the tunnel. A seepage plate installed through the installation through hole between the tunnel main body and the lower drainage channel can infiltrate the rainwater on both sides of the water retaining plate into the lower drainage channel. Cooperating with the butt joint pipe head and the collecting pipe, when a large amount of rainwater pours in, the accumulated water in the lower drainage channel can be drained out, greatly relieving the drainage pressure and ensuring that the drainage system can still work normally in extreme weather. By driving the motor to drive the control screw to rotate, the lifting of the water retaining plate can be flexibly controlled. When the rainfall is large, the water retaining plate can extend out from the inner installation block to block the entrance of the tunnel main body, effectively preventing the accumulated water from entering the tunnel main body and reducing the obstruction of the accumulated water to traffic and the damage to tunnel facilities.

[0005] The present invention provides an intelligent integrated system for drainage and flood prevention in the track traffic interval tunnel, specifically including: a tunnel main body and an interior installation block; a lower drainage channel is opened at the bottom of the tunnel main body; two groups of installation through holes are connected between the tunnel main body and the lower drainage channel; water seepage plates are respectively installed inside the two groups of installation through holes; an internal adjustment groove is provided inside the interior installation block; a water blocking plate is slidably connected inside the internal adjustment groove; external drainage ports are equidistantly opened on both sides of the inner wall of the lower drainage channel; a docking pipe head is connected to the outside of the external drainage port; the docking pipe head is connected to a collecting pipe through a pipeline; a mounting plate is fixedly connected to the inner wall of the lower drainage channel; a water level sensor is fixedly connected to the mounting plate; lower leakage through holes are equidistantly opened at the bottom of the interior installation block; the lower leakage through holes are connected to the internal adjustment groove.

[0006] Preferably, a fixed through hole is connected between the tunnel main body and the lower drainage channel; the fixed through hole is arranged between the two groups of installation through holes.

[0007] Preferably, an interior installation block is installed inside the fixed through hole; two driving motors are installed on the top of the interior installation block.

[0008] Preferably, two rectangular protrusions are provided on the outer wall of the water blocking plate, and threaded through holes are opened on the two rectangular protrusions of the water blocking plate.

[0009] Preferably, two control screws are rotatably connected inside the internal adjustment groove; the two control screws are respectively connected to the driving motors corresponding to their respective positions.

[0010] Preferably, the two rectangular protrusions of the water blocking plate are threadedly connected to the control screws.

[0011] Preferably, the collecting pipe is connected to the docking pipe head on the same side; a multi-stage monitoring component is provided inside the water level sensor.

[0012] Preferably, a reinforcement wall is fixedly connected to the middle position inside the lower drainage channel.

[0013] The intelligent integrated system for drainage and flood prevention in the track traffic interval tunnel provided by the present invention has the following beneficial effects: In the present invention, the lower drainage channel opened at the bottom of the tunnel main body can effectively collect the accumulated water in the tunnel. Through the water seepage plates installed in the installation through holes between the tunnel main body and the lower drainage channel, the rainwater on both the inner and outer sides of the water blocking plate can seep into the lower drainage channel, realizing the rapid collection and drainage of the accumulated water, and avoiding the influence of the accumulated water inside the tunnel main body on traffic. The external drainage ports equidistantly opened on both sides of the inner wall of the lower drainage channel, in cooperation with the docking pipe heads and the collecting pipe, can drain the accumulated water in the lower drainage channel when a large amount of rainwater pours in, greatly relieving the drainage pressure and ensuring that the drainage system can still work normally in extreme weather.

[0014] In addition, an internal adjustment groove is provided inside the inner mounting block. By driving the control screw rod to rotate with a driving motor, the lifting of the water baffle can be flexibly controlled. When the rainfall is large, the water baffle can extend from inside the inner mounting block to block the entrance of the tunnel main body, effectively preventing accumulated water from entering the tunnel main body, reducing the obstruction of traffic caused by the accumulated water and the damage to the tunnel facilities, and avoiding the accumulated water from affecting the operation of the water baffle. The downward leakage through hole at the bottom of the inner mounting block is connected to the internal adjustment groove, which can timely drain the accumulated water infiltrated into the internal adjustment groove, prevent the accumulated water from affecting the lifting adjustment of the water baffle, and ensure the normal operation of the water baffle.

[0015] In addition, the water level sensor installed on the mounting plate can real-time monitor the water level of the accumulated water in the downward drainage channel, and then judge the amount of rainfall. According to the monitoring results, measures can be taken in advance to avoid the accumulation of rainwater in the tunnel main body, improve the safety of tunnel operation, and thus control the extraction pump connected to the collecting pipe according to the monitoring results to increase the drainage force of the accumulated water inside the downward drainage channel.

[0016] In addition, the reinforcement wall fixedly connected at the middle position inside the downward drainage channel can increase the overall strength of the tunnel main body, effectively avoid the collapse of the tunnel after vehicle driving, ensure the normal traffic function of the tunnel, extend the service life of the tunnel, and the fixed through hole between the tunnel main body and the downward drainage channel is used to install and fix the inner mounting block, so that the inner mounting block remains stable during the process of assisting the adjustment of the water baffle, ensuring that the water baffle can accurately and reliably perform the lifting adjustment to achieve the effective blocking of the accumulated water.

[0024] Specific usage and functions of this embodiment: In the present invention, during normal use, when the vehicle is driving normally through the tunnel main body 1, the water baffle 10 is in a contracted state at this time. When rainwater appears in the tunnel, the rainwater on the inner and outer sides of the water baffle 10 will infiltrate through the water seepage plate 5. The rainwater flows into the lower drainage channel 2 through the water seepage plate 5, realizing the preliminary collection of accumulated water, and avoiding the formation of a large amount of accumulated water on the inner road surface of the tunnel main body 1, which affects the vehicle driving. In extreme weather such as heavy rain, through meteorological forecasts and upstream drainage information, and through an external control center to control the drive motor 7, the drive motor 7 drives the control screw 9 to rotate. Since the rectangular protrusions on the outer wall of the water baffle 10 are threadedly connected to the control screw 9, the rotation of the control screw 9 will cause the water baffle 10 to slide upward and extend in the inner adjustment groove 8, gradually blocking the entrance of the tunnel main body 1, preventing the accumulated water from further pouring into the interior of the tunnel main body 1. And a large amount of rainwater pours into the lower drainage channel 2 in a short time, causing the accumulated water to accumulate inside the lower drainage channel 2. The water level sensor 15 is installed on the mounting plate 14 on the inner wall of the lower drainage channel 2, and its internal multi-stage monitoring component monitors the water level of the accumulated water in the lower drainage channel 2 in real time. When the water level rises, the water level sensor 15 transmits the monitoring data to the external control center. Through the analysis of the water level data, the current rainfall amount and the accumulated water situation can be judged. At the same time, the external control center starts the externally connected water pump, so that a suction force is formed at the position of the external discharge port 11. The external discharge ports 11 evenly distributed on both sides of the inner wall of the lower drainage channel 2 will discharge the accumulated water collected in the channel through the docking pipe head 12 with the suction force. The docking pipe head 12 is tightly connected to the external discharge port 11, and the docking pipe head 12 is connected to the collecting pipe 13 through a pipeline. The accumulated water passes through the external discharge port 11, the docking pipe head 12, and the pipeline into the collecting pipe 13 in sequence, and is finally discharged to a designated location, thereby continuously ensuring that the accumulated water in the tunnel is at a relatively low level, relieving the drainage pressure of the lower drainage channel 2, and avoiding the backflow of too much accumulated water into the interior of the tunnel main body 1.
