A water storage tank with three or five-level universal sedimentation tanks in a water-rich tunnel and a water storage method

Abstract

The present invention provides a water storage tank and water storage method having three or five universal sedimentation tanks within a water-rich tunnel, relating to the field of tunnel water storage and drainage. The water storage tank having three or five universal sedimentation tanks includes a water storage tank, wherein a first partition wall, a second partition wall, a third partition wall, and a fourth partition wall are fixedly connected to the interior of the water storage tank from right to left in sequence. The length ratio of the first, second, third, fourth, and fifth sedimentation tanks is 3:3:2:1:1. Through multi-stage sedimentation, the majority of the silt in the sewage settles in the sedimentation tanks of the first few stages, thereby resolving the problem of water pump damage caused by excessive silt, reducing the amount of impurities in tunnel drainage, and thereby improving drainage purification effects. The threaded action between the valve stem and the first partition wall causes the valve stem to drive the valve plate to slide up and down within the through groove and the sliding groove, thereby adjusting the volume of water that can be stored in the first and second sedimentation tanks, effectively increasing the water storage capacity of the water storage tank.

Description

Technical Field

[0001] The present invention relates to the technical field of tunnel water storage and drainage, and in particular to a water storage tank and a water storage method having three or five levels of universal sedimentation tanks in a water-rich tunnel. Background Art

[0002] When excavating a tunnel in a water-rich area, the amount of water gushing out of the tunnel is large. Currently, construction is carried out by entering the main tunnel through a long inclined shaft with a large longitudinal slope. The construction pumping and drainage is a long-distance graded drainage on the reverse slope, and a temporary water storage tank needs to be built in the tunnel for pumping and drainage treatment.

[0003] However, if a graded pumping and drainage system is used during the construction of a water-rich tunnel, a fixed-volume water storage tank is built within the tunnel to meet construction needs. This system then pumps the accumulated water directly out of the tunnel. If this method is used, the pumps can be easily damaged if the silt in the tank is not cleaned for extended periods. Furthermore, the pumped water can become turbid, and improper wastewater treatment can damage the environment. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the present invention provides a water storage tank and water storage method with three or five-level universal sedimentation tanks in a water-rich tunnel, which solves the problem that the water storage and drainage tank of the water-rich tunnel is not cleaned for a long time and the water pump is easily damaged.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a water storage tank with three or five general sedimentation tanks in a water-rich tunnel, including a water storage tank, wherein the first partition wall, the second partition wall, the third partition wall and the fourth partition wall are fixedly connected in sequence from right to left inside the water storage tank, a first sedimentation tank is arranged between the first partition wall and the right side of the water storage tank, a second sedimentation tank is arranged between the first partition wall and the second partition wall, a third sedimentation tank is arranged between the second partition wall and the third partition wall, a fourth sedimentation tank is arranged between the third partition wall and the fourth partition wall, and a fifth sedimentation tank is arranged between the fourth partition wall and the left side of the water storage tank, the length ratio of the first sedimentation tank, the second sedimentation tank, the third sedimentation tank, the fourth sedimentation tank and the fifth sedimentation tank is 3:3:2:1:1, and the depths of the first sedimentation tank, the second sedimentation tank, the third sedimentation tank, the fourth sedimentation tank and the fifth sedimentation tank increase in sequence.

[0006] Preferably, the first partition wall and the second partition wall constitute a water diversion wall, a through groove is passed through and provided at the middle position of the top of the water diversion wall, a sliding groove is passed through and provided at the bottom of the water diversion wall, and the sliding groove is consistent in size with the through groove, a valve stem is passed through and threadedly connected at the middle position of the top of the water diversion wall, the bottom end of the valve stem is rotatably connected to a valve plate, and the valve plate is slidably connected in the through groove and the sliding groove respectively.

[0007] Preferably, a first water trough is provided at the rear end of the top right side of the water storage tank, a second water trough is provided at the front end of the top of the third partition wall and the fourth partition wall, a plurality of drainage holes are provided on the left side of the water storage tank, and a notch is provided at one end of the top of the first partition wall and the second partition wall.

[0008] Preferably, a method for storing water in a water-rich tunnel having a water reservoir with three or five universal sedimentation tanks comprises the following steps:

[0009] S1. Water inlet

[0010] The water in the tunnel flows through the first water channel into the primary sedimentation tank. When the water level in the primary sedimentation tank reaches the gap at the top of the first dividing wall, the sewage flows through the gap into the secondary sedimentation tank. The sewage is precipitated in the same way as above until the fifth sedimentation tank is full of sewage. The sewage can then be pumped out of the tunnel through the drain hole or water pump.

[0011] S2. Adjust water storage

[0012] When it is necessary to adjust the water storage capacity of the water storage tank, first rotate the valve stem on the first partition wall. Through the threaded action between the valve stem and the first partition wall, the valve stem drives the valve plate to slide up and down in the through groove and the sliding groove. Through the principle of "short plate effect", the volume of water that can be accommodated in the primary sedimentation tank and the secondary sedimentation tank can be adjusted to meet the needs of temporary water storage tanks with different water inflows for water collection.

[0013] Working principle: The gushing water in the tunnel first enters the primary sedimentation tank through the first water trough. When the water surface in the primary sedimentation tank is flush with the notch on the top of the first partition wall, the sewage enters the secondary sedimentation tank through the notch. The sewage is precipitated in stages as above until the fifth-stage sedimentation tank is full of sewage, which can be pumped out of the cave through the drain hole or water pump. When the water storage capacity of the water storage tank needs to be adjusted, the valve stem on the first partition wall is first rotated. Through the threaded action between the valve stem and the first partition wall, the valve stem drives the valve plate to slide up and down in the through groove and the sliding groove. The volume of water that can be stored in the primary sedimentation tank and the secondary sedimentation tank can be adjusted through the principle of "short plate effect" to meet the needs of temporary water storage tanks with different gushing volumes for water collection.

[0014] The present invention provides a water storage tank and water storage method with three or five-stage universal sedimentation tanks in a water-rich tunnel. It has the following beneficial effects:

[0015] 1. The present invention allows water gushing from the tunnel to first enter the primary sedimentation tank through the first water trough. When the water level in the primary sedimentation tank is flush with the notch at the top of the first partition wall, the sewage enters the secondary sedimentation tank through the notch. The sewage is precipitated in stages as described above until the fifth sedimentation tank is full of sewage. The sewage can then be pumped out of the tunnel through a drain hole or a water pump. Through multi-stage sedimentation, most of the silt in the sewage is settled in the sedimentation tanks of the first few stages, thus solving the problem of damage to the water pump due to excessive silt and reducing the amount of impurities in the tunnel drainage, thereby improving the drainage purification effect and enhancing environmental protection.

[0016] 2. The present invention rotates the valve stem on the first partition wall, and through the threaded action between the valve stem and the first partition wall, the valve stem drives the valve plate to slide up and down in the through groove and the sliding groove. Through the principle of "short plate effect", the volume of the water storage tank in the primary sedimentation tank and the secondary sedimentation tank can be adjusted, the volume of the water storage tank can be changed, and temporary water storage tanks with different water inflows can be used to collect water, effectively improving the water storage capacity of the water storage tank and greatly reducing impurities in the pumped water.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example:

[0023] like Figure 1-3As shown, an embodiment of the present invention provides a water storage tank with three or five-level universal sedimentation tanks in a water-rich tunnel, including a water storage tank 1. The water storage tank 1 is fixedly connected with a first partition wall 7, a second partition wall 8, a third partition wall 9 and a fourth partition wall 10 from right to left in sequence. A first-level sedimentation tank 2 is provided between the first partition wall 7 and the right side of the water storage tank 1, a second-level sedimentation tank 3 is provided between the first partition wall 7 and the second partition wall 8, a third-level sedimentation tank 4 is provided between the second partition wall 8 and the third partition wall 9, a fourth-level sedimentation tank 5 is provided between the third partition wall 9 and the fourth partition wall 10, and a fifth-level sedimentation tank 6 is provided between the fourth partition wall 10 and the left side of the water storage tank 1. The first-level sedimentation tank 2, the second-level sedimentation tank 3, the third-level sedimentation tank 4 are provided between the second partition wall 8 and the third partition wall 9, The length ratio of the first sedimentation tank 2, second sedimentation tank 3, third sedimentation tank 4, fourth sedimentation tank 5, and fifth sedimentation tank 6 is 3:3:2:1:1, and the depths of the first sedimentation tank 2, second sedimentation tank 3, third sedimentation tank 4, fourth sedimentation tank 5, and fifth sedimentation tank 6 increase in sequence. The water storage tank 1 is graded using partition walls, with water troughs reserved on the upper side of the partition walls, forming a water storage tank 1 with variable volume, which has the effect of a third and fifth sedimentation tank and is used to sediment tunnel drainage. A water stop valve is installed within the partition wall of the water storage tank 1. By opening and closing the water stop valve, the water storage tank volume is changed, and temporary water storage tanks are used to collect water at different water inflow volumes. This solves the problem of constantly changing water inflow volumes in a water-rich tunnel, requiring graded pumping and drainage to be processed through the third and fifth universal sedimentation tanks before being pumped out of the tunnel. This effectively improves the water storage capacity of the water storage tank 1 and significantly reduces impurities in the pumped water.

[0024] The first partition wall 7 and the second partition wall 8 form a water diversion wall, and a through groove 13 is passed through and provided at the middle position of the top of the water diversion wall, and a sliding groove 14 is passed through and provided at the bottom of the water diversion wall, and the sliding groove 14 is the same size as the through groove 13. A valve stem 16 is passed through and threadedly connected to the middle position of the top of the water diversion wall, and a valve plate 15 is rotatably connected to the bottom end of the valve stem 16, and the valve plate 15 is slidably connected in the through groove 13 and the sliding groove 14 respectively. A large water storage tank 1 is set in the emergency parking zone of the tunnel, and the water storage tank 1 is divided into five levels by the partition wall. The valve stem 16 and the valve plate 15 are used to change the volume of the water storage tank 1 and the conversion of the third and fifth sedimentation tanks. The water pump is placed in the fifth sedimentation tank 6, and the gushing water is pumped out of the cave by the water pump after being precipitated through the third and fifth sedimentation tanks. This method can change the volume of the water storage tank 1 according to the amount of water inflow in the tunnel, and at the same time, precipitate the sewage, thereby solving the problem of water pump damage caused by excessive silt, and reducing the amount of impurities in the tunnel drainage, thereby improving the drainage purification effect, improving environmental protection, and greatly improving the construction efficiency and quality of water-rich tunnels.

[0025] A first water trough 17 is provided at the rear end of the top right side of the water storage tank 1, a second water trough 11 is provided at the front end of the top of the third partition wall 9 and the fourth partition wall 10, a plurality of drainage holes 12 are provided on the left side of the water storage tank 1, and a notch is provided at one end of the top of the first partition wall 7 and the second partition wall 8.

[0026] A method for storing water in a water-rich tunnel with a water storage tank having three or five universal sedimentation tanks comprises the following steps:

[0027] S1. Water inlet

[0028] The water in the tunnel first flows into the primary sedimentation tank 2 through the first water channel 17. When the water level in the primary sedimentation tank 2 reaches the gap at the top of the first partition wall 7, the sewage flows into the secondary sedimentation tank 3 through the gap. The sewage is precipitated in the same way as above until the fifth sedimentation tank 6 is full of sewage. The sewage can then be pumped out of the tunnel through the drain hole 12 or a water pump.

[0029] S2. Adjust water storage

[0030] When it is necessary to adjust the water storage capacity of the water storage tank, first rotate the valve stem 16 on the first partition wall 7. Through the threaded action between the valve stem 16 and the first partition wall 7, the valve stem 16 drives the valve plate 15 to slide up and down in the through groove 13 and the sliding groove 14. Through the principle of "short plate effect", the volume of water that can be accommodated in the primary sedimentation tank 2 and the secondary sedimentation tank 3 can be adjusted to meet the needs of temporary water storage tanks with different water inflows for water collection.

[0031] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
