Description

Technical Field

[0001] The invention relates to the field of drainage equipment, and in particular to a deep tunnel drainage shaft with energy dissipation function. Background Art

[0002] In recent years, with the continuous advancement of urbanization, the scale of urban construction has continued to expand, and the area of ​​impermeable land such as hard pavement and buildings has increased, which has changed the underlying surface conditions of the basin, greatly reducing rainfall infiltration and interception, resulting in a shortened rainfall runoff time, faster discharge speed, and a significant increase in runoff and peak flow. Problems such as insufficient capacity of urban drainage systems and low drainage standards have become increasingly prominent. In addition, due to frequent extreme weather, urban rainstorms and waterlogging, overflow pollution and other incidents have occurred frequently, which not only caused difficulties for road traffic and residents' travel, but also caused disasters such as black and smelly water bodies in the downstream, seriously threatening the development of the city and the safety of people's lives and property.

[0003] At present, most cities in my country are facing problems such as rainstorm waterlogging and non-point source pollution. In order to effectively solve these problems, it is urgent to transform and improve the original drainage system in the city. However, due to the limitations of spatial conditions, transformation costs, construction impacts and other factors, the transformation of shallow pipe networks is difficult and the effect is not very obvious. Therefore, the deep tunnel drainage system project with the concept of sponge city construction has become the main way to solve urban waterlogging disasters. The deep tunnel project has the functions of rainwater regulation and storage, drainage regulation and storage, and control of combined overflow pollution. The deep tunnel drainage system is mainly composed of five parts: the main tunnel, the shaft, the drainage pump group, the ventilation facilities, and the mud discharge facilities. Among them, the shaft is the water inlet point for combined sewage or storm runoff to enter the deep tunnel through the shallow pipe network. During rainfall, the excess rainwater or combined sewage is sent to the underground deep tunnel through the shaft, so as to reduce the pressure of the shallow drainage network, reduce urban road surface waterlogging, and prevent waterlogging from affecting transportation. It can be seen that the reasonable design of the shaft in the deep tunnel is extremely important for the transfer of rainwater and sewage and the safe and stable operation of the deep tunnel drainage system.

[0004] Due to the great depth of the vertical shaft, the impact of the water flow on the bottom of the well is relatively large, which can easily cause damage to the bottom of the well.

DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0023] The deep tunnel drainage shaft with energy dissipation function of the present invention is as follows: Figure 1 As shown, it includes a well body 1, wherein the top of the well body 1 is provided with a water inlet 2, and the bottom is provided with a drain 3 for connecting to a deep tunnel. The well body 1 has a rectangular cross section, and the water inlet 2 is connected to the drainage system on the surface to collect rainwater and discharge it into the well body 1, while the drain 3 discharges the water in the well body 1 into the deep tunnel.

[0024] The well body 1 is divided into a cleaning chamber and a drainage chamber 7 by a second partition 8, and a second water inlet channel 10 connected to the drainage chamber 7 is provided at the bottom of the cleaning chamber. The cleaning chamber is used to remove solid impurities in the water to avoid clogging of the deep tunnel. The second water inlet channel 10 connects the cleaning chamber and the drainage chamber 7 to discharge the rainwater after cleaning into the drainage chamber 7. The drain port 3 is provided in the drainage chamber 7 and connected to the deep tunnel to discharge the water in the drainage chamber 7 into the deep tunnel.

[0025] A vertical drainage column 15 is arranged in the drainage cavity 7. The drainage column 15 can be a concrete column. The bottom of the drainage column 15 is connected to the second water inlet channel 10. The side wall of the drainage column 15 is provided with a plurality of drainage short pipes 151. The cross section of the drainage column 15 can be rectangular. A drainage short pipe 151 is arranged on each side. There are 4 drainage short pipes 151 in total, which disperse and discharge rainwater into the drainage cavity 7. A water retaining piston 152 is arranged inside the drainage column 15. There is a distance between the water retaining piston 152 and the inner wall of the drainage column 15. The water retaining piston 152 is located below the drainage short pipe 151. The upper surface of the water retaining piston 152 is connected to the top plate of the drainage column 15 through an elastic mechanism. The water-blocking piston 152 serves to block the water flow and reduce the water flow speed. Specifically, after rainwater enters the drainage column 15, it first reaches the water-blocking piston 152. The water flow impacts the water-blocking piston 152, causing the elastic mechanism to be compressed. The kinetic energy of the water flow is converted into the potential energy of the elastic mechanism, the flow rate of water is reduced, and the impact force is weakened. Then, the water is sprayed out through multiple drainage short pipes, which can avoid the damage to the well body caused by the large impact force of the water flow.

[0026] In order to ensure that the water flow first impacts the water retaining piston 152 and then reaches the drainage short pipe 151, and to avoid the water flow impact force driving the water retaining piston 152 to move above the drainage short pipe 151, the inner wall of the drainage column 15 is provided with an upper limit clip 156 and a lower limit clip 157, and the water retaining piston 152 is arranged between the upper limit clip 156 and the lower limit clip 157, and the upper limit clip 156 is located at the bottom of the drainage short pipe 151, ensuring that the lower surface of the water retaining piston 152 is lower than the center line of the drainage short pipe 151. The upper limit clip 156 and the lower limit clip 157 can limit the drainage short pipe 151, avoid the elastic mechanism shortening a large distance and causing damage, and also avoid the position of the water retaining piston 152 being higher than the drainage short pipe 151 and affecting the energy dissipation effect.

[0027] The elastic mechanism may adopt a single spring mechanism, etc. Preferably, the elastic mechanism includes a telescopic base 153 and a spring 154, wherein the telescopic base 153 is connected to the water-blocking piston 152 via a connecting rod 155, and the spring 154 is arranged between the water-blocking piston 152 and the telescopic base 153. The telescopic base 153 may adopt a manually adjustable telescopic structure, or may adopt an existing hydraulic automatic telescopic pile, etc., which can be telescoped to change the length. The water-blocking piston 152 and the connecting rod 155 are slidably matched to ensure that the water-blocking piston 152 can slide up and down, and the connecting rod 155 plays a guiding role to ensure the stability of the water-blocking piston 152.

[0028] The drainage chamber 7 is provided with an inspection platform 26, and the inspection platform 26 is provided with a control platform 27. The telescopic base 153 is connected with a pressure switch 28, and the pressure switch 28 and the telescopic base 153 are both connected to the control platform 27. The pressure switch 28 can detect the pressure on the telescopic base 153, that is, the impact force of the water flow on the telescopic base 153, and the pressure switch 28 transmits the detection value to the control platform 27. When the impact force is large, it indicates that the water flow speed is large, and the control platform 27 controls the telescopic base 153 to extend a distance, so that the water retaining piston 152 moves downward, can contact the water flow at a lower position, increase the compressible length of the spring 154, and can convert more kinetic energy of water into potential energy of the spring 154. When the impact force is small, it indicates that the water flow speed is small, and the control platform 27 controls the telescopic base 153 to shorten a distance.

[0029] The impurity removal chamber is divided by a first partition plate 4 into a filter chamber 5 and a sedimentation and mud removal chamber 6 which are arranged in sequence from top to bottom. A first water inlet channel 9 which connects the filter chamber 5 and the sedimentation and mud removal chamber 6 is arranged at one end of the first partition plate 4, and a second water inlet channel 10 is arranged on a second partition plate 8 at an end away from the first water inlet channel 9; a filter mechanism 11 is arranged in the filter chamber 5, and a mud discharge mechanism is arranged at the bottom of the sedimentation and mud removal chamber 6.

[0030] The well body 1 is divided into a filter chamber 5, a sedimentation and mud removal chamber 6 and a drainage chamber 7 which are arranged in sequence from top to bottom by a first partition plate 4 and a second partition plate 8. A first water inlet channel 9 connecting the filter chamber 5 and the sedimentation and mud removal chamber 6 is provided at one end of the first partition plate 4, and a second water inlet channel 10 connecting the sedimentation and mud removal chamber 6 and the drainage chamber 7 is provided at one end of the second partition plate 8 away from the first water inlet channel 9; a filter mechanism 11 is provided in the filter chamber 5, and a mud discharge mechanism is provided at the bottom of the sedimentation and mud removal chamber 6.

[0031] The first partition 4 and the second partition 8 can be made of concrete plates or metal plates. A filtering mechanism 11 is provided in the filtering chamber 5 for filtering rainwater to remove large impurities. The filtering mechanism 11 can adopt various existing filtering devices. Preferably, the filtering mechanism 11 includes a coarse grid plate and a fine grid plate. The number of the coarse grid plate and the fine grid plate can be one or multiple as required. The rainwater first flows through the coarse grid plate and then flows through the fine grid plate. The solid impurities in the water are intercepted, which can prevent large solid impurities from entering the deep tunnel and causing blockage of the deep tunnel.

[0032] The sedimentation and mud removal chamber 6 is used to statically sediment rainwater, thereby removing the mud in the rainwater. During the sedimentation, the mud is discharged by the mud discharge mechanism to prevent the mud at the bottom of the sedimentation and mud removal chamber 6 from continuously accumulating and thickening.

[0033] Rainwater enters the filter chamber 5 through the water inlet 2, and after being filtered by the filter mechanism 11, enters the sedimentation and desilting chamber 6 through the first water inlet channel 9, and is allowed to settle in the sedimentation and desilting chamber 6 to remove most of the silt, and then enters the drainage chamber 7 through the second water inlet channel 10, and finally enters the deep tunnel through the drainage port 3. The silt at the bottom of the sedimentation and desilting chamber 6 is continuously discharged by the silt discharge mechanism.

[0034] The rainwater is filtered by the filtering mechanism 11 to remove large solid impurities in the water, and the silt in the water is settled by static sedimentation in the sedimentation and desilting chamber 6, which can eliminate most of the fine silt in the water, thereby greatly reducing the solid matter in the water and avoiding blockage of deep tunnels.

[0035] In order to prevent rainwater from flowing quickly in the sedimentation and mud removal chamber 6 and affecting the sedimentation effect, the water inlet 2 is set at one end of the filter chamber 5, and a vertical baffle 12 is set at the end of the first partition 4 away from the water inlet 2. The baffle 12 and the side wall of the well body 1 form a first water inlet channel 9, and there is a gap between the lower end of the baffle 12 and the second partition 8; the second partition 8 is set at one end away from the first water inlet channel 9. A vertical overflow plate 13 is set, and there is a gap between the upper end of the overflow plate 13 and the first partition 4. The filter mechanism 11 is set on the first partition 4 between the water inlet 2 and the baffle 12 to ensure that the rainwater first passes through the filter mechanism 11 and then enters the first water inlet channel 9. At the same time, the overflow plate 13 and the side wall of the well body 1 form a water inlet chamber, and the second water inlet channel 10 is set at the bottom of the water inlet chamber. The portion between the baffle 12 and the overflow plate 13 serves as the main static sedimentation space. The baffle 12 and the overflow plate 13 separate the first water inlet channel 9, the water inlet cavity and the main static sedimentation space, avoiding a large impact force generated by direct entry into the main static sedimentation space, which is beneficial for reducing the fluctuation of rainwater in the main static sedimentation space and increasing the sedimentation effect. At the same time, the rainwater in the main static sedimentation space flows into the water inlet cavity from the top of the overflow plate 13, further reducing the fluctuation of rainwater, and at the same time reducing the amount of sediment carried, thereby avoiding sediment settled at the bottom of the main static sedimentation space from entering the second water inlet channel 10.

[0036] In order to further improve the sedimentation effect, a plurality of corrugated sedimentation plates 25 are arranged between the baffle plate 12 and the overflow plate 13. The sedimentation plates 25 are made of plastic or metal thin plates, and the distance between two adjacent sedimentation plates 25 is small, which promotes sedimentation in the water by blocking the water flow.

[0037] In order to facilitate the discharge of the settled mud and sand, a plurality of V-shaped sedimentation tanks 16 are provided at the bottom of the sedimentation and mud removal chamber 6, and the mud discharge mechanism includes a plurality of mud discharge branch pipes 17 and a mud discharge main pipe 18, wherein the mud discharge branch pipe 17 is connected to the mud discharge main pipe 18, and the mud discharge main pipe 18 is connected to the mud discharge pump 19. After the V-shaped sedimentation tank 16 is provided, the mud and sand will be concentrated into the sedimentation tank 16, and then under the action of the mud discharge pump 19, the mud and sand will enter the mud discharge branch pipe 17, and then enter the mud accumulation chamber through the mud discharge main pipe 18, and finally be discharged out of the shaft.

[0038] The second water inlet channel 10 may be a pipe, a duct, etc. Preferably, the second water inlet channel 10 includes a siphon water collecting bucket and a drainage pipe. The siphon water collecting bucket is arranged at the bottom of the water inlet cavity. The upper end of the drainage pipe is connected to the siphon water collecting bucket, and the lower end of the drainage pipe extends into the drainage cavity 7 and is connected to the drainage column 15. The siphon water collecting bucket utilizes the siphon effect to absorb water and drain water. It can adopt the existing technology and has the advantages of fast drainage speed.

[0039] Since the shaft is deep, rainwater has a great impact force after entering. In order to reduce the scouring force of rainwater on the inside of the shaft, an anti-scouring layer 14 is laid at the bottom of the first water inlet channel 9. The anti-scouring layer 14 can be made of solid particles, such as pebbles.

[0040] In order to facilitate manual entry into the well body and overhaul of the equipment, a maintenance well 20 is also included, which is separated from the well body 1 by a vertical side wall, and a staircase 21 is arranged in the maintenance well 20. The wall between the maintenance well 20 and the well body 1 is provided with a sealed door that can be opened and closed.

[0041] In order to prevent the inner cavity at the top of the drainage column 15 from being closed and affecting the water absorption effect of the siphon collecting bucket, a ventilation pipe is connected to the top of the drainage column 15 , one end of the ventilation pipe is connected to the drainage column 15 , and the other end can be extended into the inspection well 20 .

[0042] In order to monitor the water flow of the well body 1, a filter ball 22 is provided at the bottom of the first water inlet channel 9, and the filter ball 22 is connected to a monitoring pipe 23, and a hydraulic alarm 24 and a valve are provided on the monitoring pipe 23. The filter ball 22 is used to filter rainwater to prevent the monitoring pipe 23 from being blocked, and the hydraulic alarm 24 is used to detect the water flow, and an alarm can be sounded when the water flow is large. In order to facilitate the control and maintenance of the hydraulic alarm 24 and the valve, the hydraulic alarm 24 and the valve are arranged in the inspection well 20.
