Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy construction engineering, in particular to a coastal tide-blocking sluice with a double working door structure. Background Art

[0002] Coastal tidal sluice gates are a type of water conservancy engineering facility used to prevent tidal intrusion into coastal areas. They are usually constructed of concrete, steel bars and other materials to block the invasion of tidal water and protect residents, farmland and infrastructure in coastal areas from the harm of tidal water. Coastal tidal sluice gates can be opened and closed as needed to respond to tidal influx at different time periods, thereby effectively controlling the inflow and outflow of seawater and ensuring the safety of coastal areas.

[0003] Traditional coastal tidal sluice gates are generally equipped with inland river inspection gates, working gates and offshore inspection gates, but they are all single-working gate sluice structures, such as Figure 1 and 2 , take the breast wall type single working gate sluice as an example:

[0004] For this sluice, when the water level on the inner river side of the outer breast wall is high, although the waterstop rubber is denser and can prevent the loss of fresh water from the inner river, when the tide level on the outer sea side is high, the waves will rush into the room through the maintenance platform hole, affecting the safety of electricity and personnel; and when the tide level on the outer sea side is not very high but higher than the height of the working gate, the waterstop rubber is not dense enough, and the tide can easily flow into the inner river side through the gaps in the waterstop rubber, causing the fresh water on the inner river side to become salty and causing bad public opinion.

[0021] The sluice gate is an important flood control and drainage gate in the basin, which needs to be opened and closed frequently. In the prior art, the outer breast wall type single working gate sluice gate is taken as an example. Figure 1 , 2 As shown,

[0022] The sluice is equipped with a lock chamber 1, a hoisting machine room 6, a maintenance platform 4, a hoisting platform 5, a traffic bridge 7, etc. The top elevation of the wave-breaking wall 16 is 8.80m, the top elevation of the wave-breaking wall 16 is 8.80m, the elevation of the traffic bridge 7 is 7.60m, and the ground elevation of the maintenance platform 4 is 7.75m. The lock chamber 1 is 19m long and has a scale of 3 holes × 5m. Each hole in the lock chamber 1 is equipped with a working gate, and a flat sliding steel gate is selected. Each working gate is opened and closed by a winch-type hoist 15; an inspection door is reserved before and after the working gate. The inland river inspection door and the 2 inspection doors on the open sea side are both exposed-top flat sliding steel stacked beam doors, each of which is opened and lifted by an electric hoist 14. Since the fresh water resources on the inland river side 3 are relatively precious, in order to avoid the loss of fresh water, this plan considers the use of an external breast wall structure.

[0023] Then, in the above technical scheme, when the water level of the outer breast wall on the inner river side is high, although the water-stop rubber has a high density and can prevent the loss of fresh water from the inner river, when the tidal level 2 on the outer sea side is high, the waves will rush into the room through the maintenance platform hole, affecting the safety of electricity and personnel; and when the tidal level 2 on the outer sea side is not very high but higher than the height of the working gate, the water-stop rubber is not dense, and the tide can easily flow into the inner river side through the gap of the water-stop rubber, causing the fresh water on the inner river side to become salty and causing bad public opinion.

[0024] For this purpose, an embodiment of this case is proposed, and the technical solution is (two working gates + inland river side inspection door 10): Figure 3 As shown, the lock chamber 1 connects the open sea side 2 and the inland river side 3, the lock chamber 1 is located in the embankment, and an inspection platform 4, an opening and closing platform 5, an opening and closing machine room 6, and a traffic bridge 7 are arranged on the lock chamber 1. The ground elevation of the inspection platform 4 is 7.75m, and the surface elevation of the traffic bridge 7 is 7.60m. The traffic bridge 7 is connected with the road surface on the top of the embankment. The lock chamber 1 is 19m long and has a scale of 3 holes × 5m. Two working gates and an inland river side inspection door 10 are arranged in each hole in the lock chamber 1, which are the first working gate 8, the second working gate 9 and the inland river side inspection door 10 respectively. The first working gate also serves as the open sea side 2 inspection door. Both working gates are flat sliding steel gates. Each of the first working gate 8, the second working gate 9 and the inland river side inspection door 10 are opened and closed by the opening and closing device.

[0025] In order to prevent the waves from entering the lock chamber 1 from the holes of the maintenance platform 4 at high tide, preferably, the first working gate 8 is provided with an outer sea side breast wall 11 near the outer sea side 2, and a water stop rubber 12 is provided between the outer sea side breast wall 11 and the first working gate 8. Since the tide level is blocked by the outer sea side breast wall 11, the waves cannot enter the lock chamber 1 through the holes of the maintenance platform 4 corresponding to the second working gate inside; the second working gate 9 is provided with an inner river side breast wall 13 near the inner river side 3, and a water stop rubber 12 is provided between the inner river side breast wall 13 and the second working gate 9. Leakage from the inner river and the outer sea can be blocked by another gate.

[0026] As a preferred embodiment of this embodiment, the inland river side inspection door 10 is a steel stacked beam door, and an electric hoist 14 is suspended on the opening and closing platform 5. The inland river side inspection door 10 is opened and closed by the electric hoist 14, and the model of the electric hoist 14 is MD2×10t.

[0027] As a preferred embodiment of the present invention, a plurality of winch-type gate hoists 15 are installed on the opening and closing platform 5, and the plurality of winch-type gate hoists 15 correspondingly pull the first working gate 8 and the second working gate 9, and the model of the winch-type gate hoists 15 is QPQ-2×250kN.

[0028] As a preferred embodiment of the present invention, a wave-breaking wall 16 is provided on the deck of the traffic bridge 7 close to the open sea side 2, and the top elevation of the wave-breaking wall 16 is 8.80 m.

[0029] Based on the above analysis and comparison, although the investment in this embodiment is slightly increased, it combines the advantages of the inner breast wall and the outer breast wall, avoids their shortcomings, improves the space utilization rate of the upper structure, ensures the safe operation of the sluice gate during the flood season, and avoids public opinion that may be detrimental to the unity of the masses.

[0030] Working principle: When a coastal tidal sluice gate with a double working gate structure is in use, if one working gate cannot work during the flood season, the other working gate can be activated without affecting the safety during the flood season;

[0031] When water seepage occurs when one working gate is opened, two working gates can be started at the same time; seawater from the open sea leaking through the gap of the first working gate will be blocked outside the second working gate, and will not affect the fresh water on the inland river side; fresh water from the inland river leaking through the gap of the second working gate will be blocked inside the first working gate, and the fresh water from the inland river will basically not be lost.

[0032] The two maintenance gates and opening and closing equipment on the open sea side are arranged in the upper building. There is no need to set up a separate storage space, and the upper structure space utilization rate is high; the gates are easy to maintain and open and close; the waves cannot enter the room, the indoor floor is dry, and the service life of the indoor equipment is not affected.

[0033] Although 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 the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
