[0037] Embodiment 1 As shown in Figures 1-8 The present embodiment discloses a dock gate sealing structure, comprising: Two oppositely arranged dock piers 1, a dock gate bottom plate 10 is arranged between the dock piers 1; The dock gate 2 is placed on the dock gate bottom plate 10, and the dock gate 2 and the dock pier 1 have a water storage cavity 20 therebetween; The water sealing gate 3 is arranged on the inner and outer sides of the dock gate 2, the water sealing gate 3 is placed on the dock gate bottom plate 10, the water sealing strip assembly 6 is arranged on the two sides of the water sealing gate 3, and the two sides of the water sealing gate 3 are respectively used for abutting with the dock pier 1 and the dock gate 2.
[0038] In the present embodiment, the water sealing strip assembly 6 is arranged on the two sides of the water sealing gate 3, and the two sides of the water sealing gate 3 are respectively abutted with the dock pier 1 and the dock gate 2 to realize the sealing of the water storage cavity 20 between the dock gate 2 and the dock pier 1. Through the cooperation of the dock pier 1, the dock gate 2 and the water sealing gate 3, the water sealing of the dock gate is realized. Further, the water sealing gate 3 is arranged on the inner and outer sides of the dock gate 2, and the two sides of the water sealing gate 3 are respectively used for abutting with the dock pier 1 and the dock gate 2, so that the two water sealing gates 3 are used to seal the two ends of the water storage cavity 20, so that the water storage cavity 20 forms a space with both ends sealed; In use, the water in the water storage cavity 20 is pumped out by the water pumping equipment, so that the water level of the water storage cavity 20 is lowered, so that the water pressure on the inner and outer sides of the water sealing gate 3 changes, and the water pressure on the outer side of the water sealing gate 3 is higher than that on the inner side. Under the action of the outer side water pressure, the water sealing gate 3 is pressed tightly on the dock pier 1 and the dock gate 2, further enhancing the sealing performance of the water sealing gate 3. Compared with the ordinary steel gate, the sealing performance of the water sealing gate 3 increases synchronously with the outer side water pressure, and the sealing performance can be maintained at high pressure.
[0039] When the dock needs to be drained in the future, after the water in the dock is pumped out, the water stop gate 3 on the inner side of the dock gate 2 is pulled tightly together with the dock gate 2 by a steel wire after the water level in the dock is lowered, but it should be noted that the water stop gate 3 on the inner side of the dock gate 2 does not affect the water stop of the dock gate 2, because the water level on the outer side of the dock gate 2 does not change when the water in the dock is pumped out, so the water pressure on the outer side of the dock gate 2 will always press the water stop gate 3 on the outer side of the dock gate 2 tightly, making the water stop gate 3 on the outer side of the dock gate 2 abut and press tightly on the dock pier 1 and the dock gate 2; Wherein, the inner side of the dock gate 2 refers to the side of the dock gate 2 close to the dock, and the outer side of the dock gate 2 refers to the side of the dock gate 2 away from the dock.
[0040] The purpose of setting the water stop gate 3 on the inner side of the dock gate 2 in this embodiment is to seal both ends of the water storage cavity 20 by setting water stop gates 3 on both the inner and outer sides of the dock gate 2, and then lowering the water level on the inner side of the water stop gate 3 by pumping water out of the water storage cavity 20, so that the water level on the inner side of the water stop gate 3 is lower than the water level of the outer water area (such as seawater or river water), thereby utilizing the water pressure difference to press the water stop gate 3 tightly with the water pressure of the outer water area; Compared with the method of setting water stop gate 3 only on the outer side of the dock gate 2 and lowering the water level of the water stop gate 3 by pumping water out of the dock, the present embodiment has the advantages of less water pumping, faster effect, higher efficiency, and early realization of the sealing and water stop of the dock gate.
[0041] In one or more embodiments, as shown in Figures 3-4 Also includes: The guide sill 4 is arranged at the bottom of the dock pier 1, and the guide sill 4 is connected with the dock floor 10; The first water stop belt 5 is continuously laid on the dock floor 10, and both ends of the first water stop belt 5 extend to the guide sill 4 on both sides of the dock gate 2, and the water stop gate 3 and the dock gate 2 press the first water stop belt 5; The side of the bottom of the water stop gate 3 away from the dock gate 2 abuts against the guide sill 4, as shown in Figure 8 .
[0042] The guide sill 4 provides a positioning reference for the water stop gate 3 to avoid installation deviation; The first water stop belt 5 forms a seal on the bottom of the water stop gate 3 and the dock gate 2 after being pressed down by the water stop gate 3 and the dock gate 2, eliminating the leakage channel on the bottom of the water stop gate 3 and the dock gate 2, and at the same time, cooperating with the water stop strip assembly 6 on the side of the water stop gate 3 to form double sealing of the side and the bottom of the dock gate 2, further improving the water stop reliability.
[0043] In the embodiment, the guide sill 4 is fixed at the bottom of the dock block 1, and the guide sill 4 is used to gradually guide the bottom of the water stop gate 3 to the correct installation position, prevent the water stop gate 3 from rigidly colliding with the dock block 1, and ensure that the gate is stably and accurately in place; Meanwhile, the first water stop belt 5 of the embodiment is continuously laid on the dock gate bottom plate 10, the end of the first water stop belt 5 extends to the guide sill 4, and the dock gate 2 is pressed on the first water stop belt 5 after sinking to the bottom, so that the first water stop belt 5 is elastically deformed, thereby generating an initial sealing pressure on the contact surface between the bottom of the dock gate 2 and the first water stop belt 5, and realizing the sealing of the dock gate 2; When the water stop gate 3 falls onto the dock gate bottom plate 10, the water stop gate 3 presses the first water stop belt 5, so that the first water stop belt 5 is elastically deformed, thereby generating an initial sealing pressure on the contact surface between the bottom of the water stop gate 3 and the first water stop belt 5, and realizing the sealing of the water stop gate 3; Further, as shown in Figure 1 、 Figure 3 、 Figure 8 , the end of the first water stop belt 5 extends to the guide sill 4, so that the first water stop belt 5 covers the connection area of the guide sill 4 and the dock gate bottom plate 10, eliminates the sealing breakpoint at the connection of the guide sill 4 and the dock gate bottom plate 10, forms a complete and continuous barrier for the bottom sealing, avoids the leakage channel caused by discontinuous laying, and further strengthens the bottom water stop effect.
[0044] Specifically, the first water stop belt 5 is an Ω-shaped flexible water stop belt, and specifically, the first water stop belt 5 is an Ω-shaped rubber water stop belt.
[0045] In an optional embodiment, as shown in Figure 9 、 Figure 10 , the water stop gate 3 comprises a rectangular box body 31 and a base 32 connected with each other, the water stop strip assembly 6 is vertically arranged on two sides of the rectangular box body 31, and the water stop strip assembly 6 extends downward and is arranged on two sides of the base 32; The side of the base 32 away from the dock gate 2 abuts against the guide sill 4.
[0046] When the water pressure difference between the inside and outside of the water stop gate 3 is generated, the water stop strip assembly 6 of the water stop gate 3 is tightly attached to the dock block 1 and the dock gate 2 to achieve the water stop effect, wherein the side of the rectangular box body 31 and the side of the base 32 form the side of the water stop gate 3, and the water stop strip assembly 6 is arranged on the side of the rectangular box body 31 and the base 32, so as to perform the compression water stop operation of the water stop gate 3.
[0047] Further, the rectangular box 31 improves the overall structural strength of the water stop gate 3, and the anti-deformation ability is enhanced. The base 32 abuts against the guide sill 4 to guide the water stop gate 3 during installation, prevent rigid collision between the water stop gate 3 and the caisson pier 1, and ensure that the gate is stably and accurately positioned.
[0048] Further, as shown in Figures 5-7 the guide sill 4 includes a slope portion 41, which is arranged in an L shape, and the upper end of the slope portion 41 is connected to the caisson pier 1, and the lower end of the slope portion 41 is connected to the caisson floor 10. The base 32 has a wedge-shaped portion 320 matched with the slope portion 41, which is arranged in an L shape.
[0049] The matching structure of the L-shaped slope portion 41 and the wedge-shaped portion 320 increases the contact area therebetween, and under the action of water pressure, the wedge-shaped portion 320 is further pressed against the slope portion 41, thereby enhancing the sealing between the base 32 and the guide sill 4. The gap is automatically compensated by the wedge-shaped matching, thereby avoiding leakage caused by poor fitting.
[0050] In the embodiment, to better adapt the water stop gate 3 to the guide sill 4, the wedge-shaped portion 320 matched with the slope portion 41 is arranged on the base 32, so that the water stop gate 3 can better fit the guide sill 4 during installation. When the water stop gate 3 bears a horizontal force, the slope portion 41 of the guide sill 4 becomes a key component for bearing and transmitting the horizontal force at the bottom of the gate, safely transmits the horizontal force to the caisson pier 1, and the guide sill 4 and the base 32 of the water stop gate 3 jointly bear the vertical weight of the gate, thereby ensuring that the gate stands stably. In an optional embodiment, as shown in Figure 4 the water stop strip assembly 6 includes at least two water stop strips arranged along the length direction of the water stop gate 3. The plurality of water stop strips are distributed along the length direction of the rectangular box 31, and form multiple seals on the side surface of the rectangular box 31. Even if a single water stop strip fails locally, the sealing can still be ensured by other water stop strips, thereby greatly improving the sealing reliability of the side surface of the rectangular box 31.
[0051] Further, as shown in Figure 11 the water stop strip assembly 6 includes a first water stop strip 61 and a second water stop strip 62. The first water stop strip 61 is an Ω-shaped flexible water stop strip, and the second water stop strip 62 is a rectangular water stop strip. Specifically, the first water stop strip 61 is an Ω-shaped rubber water stop strip, and the second water stop strip 62 is a rectangular rubber water stop strip.
[0052] The Ω-shaped flexible waterstop has elastic deformation capacity, can automatically fill the small gap under the action of water pressure, adapt to structural deformation and settlement; the inner rectangular waterstop provides rigid support and enhances the sealing pressure, and the two cooperate to form a composite sealing effect, so that the sealing performance is more stable with the increase of water pressure, solving the problem that the traditional waterstop is sensitive to deformation.
[0053] In an optional embodiment, as shown in the figure, reinforcing ribs are arranged inside the rectangular box 31, and the reinforcing ribs are arranged along the length direction of the rectangular box 31 at intervals.
[0054] The reinforcing ribs enhance the buckling resistance of the rectangular box 31, effectively suppress structural deformation under high water pressure, ensure that the side waterstop is always tightly attached to the pier 1 and the gate 2, maintain stable sealing pressure, and ensure long-term waterstop effect.
[0055] In an optional embodiment, as shown in the figure, Figure 11 the rectangular box 31 includes a first front water baffle 311, a first side water baffle 312, and a back plate 313, two first side water baffles 312 are connected to the two sides of the first front water baffle 311, and the first side water baffles 312 are arranged at an obtuse angle with the first front water baffle 311; the back plate 313 connects the two first side water baffles 312; The waterstop assembly 6 is arranged on the first side water baffle 312, and the two first side water baffles 312 are respectively used to abut against the pier 1 and the gate 2.
[0056] The obtuse angle arrangement of the first side water baffle 312 makes the contact angle of the waterstop with the pier 1 and the gate 2 more reasonable, and under the action of water pressure, the stress of the waterstop is more uniform, the sealing pressure distribution is more stable, and leakage caused by insufficient local pressure is avoided, improving the effectiveness of side sealing.
[0057] The first waterstop 61 and the second waterstop 62 are fixed on the first side water baffle 312 by bolts.
[0058] As shown in the figure, Figure 11 the rectangular box 31 further includes a rectangular panel 314, and the rectangular panel 314 is connected to the top of the first front water baffle 311, the first side water baffle 312, and the back plate 313; The lifting lug 7 is connected to the rectangular panel 314, and when the water gate 3 is installed, the lifting lug 7 is used for horizontal traction direction during installation, so that the water gate 3 is pulled and moved through the lifting lug 7, and the water gate 3 is temporarily fixed by tightening the lifting lug 7 through the steel wire rope.
[0059] Specifically, the rectangular box 31 adopts a Q235 steel plate combined structure, the length of the water stop gate 3 is 17.3 m, the top elevation is designed as +4.0 m, and the bottom elevation is designed as -13.3 m; the first side water baffle 312 and the first front water baffle 311 on both sides all adopt a steel plate with a wall thickness of 15 mm, and a steel plate with a thickness of 12 mm is used as a reinforcing rib 33 to connect the three water baffles and the back plate 314; the spacing of the reinforcing rib 33 is arranged with the elevation -3.3 m as a boundary, the vertical spacing below the boundary is 0.5 m, and the vertical spacing above the boundary is 1.0 m.

[0067] Embodiment 3 On the basis of embodiment 1, the present embodiment discloses a use method of a dock gate water sealing structure, based on the dock gate water sealing structure described in embodiment 1, comprising the following steps: S1: floating a plurality of water sealing gates 3 to the inside and outside of the dock gate respectively; S2: floating the dock gate 2 to the two dock piers 1, and then sinking the dock gate 2 to the dock gate bottom plate 10; S3: floating the water sealing gate 3 to the interface between the dock pier 1 and the dock gate 2, and then pulling the water sealing gate 3 to block the two ends of the water storage cavity 20; S4: pumping water in the water storage cavity 20, so that the water level in the water storage cavity 20 is lowered to the designed water level, and the water sealing gate 3 is pressed tightly by the water pressure difference between the inside and outside of the water sealing gate 3.
[0068] The water pressure difference formed by pumping makes the water sealing gate 3 automatically press tightly against the dock pier 1 and the dock gate 2, realizing "self-reinforcing" sealing, and the higher the pressure outside the dock gate 2, the greater the sealing pressure of the water sealing gate 3, thereby solving the problem of low efficiency and sealing pressure not changing with water pressure in traditional mechanical pressing, and improving the installation efficiency and sealing reliability.
[0069] In an optional embodiment, before the water sealing gate 3 is first sunk, solvents such as acetone and alcohol are used to clean the slope part 41 of the guide sill 4 and the water baffle of the water sealing gate 3, so as to ensure that there is no oil stain, rust, dust and other impurities.
[0070] In an alternative embodiment, the water stop is initially pressed by the fixing member such as bolt pre-installed on the water stop gate 3, but not immediately fastened completely; Then the position of the water stop is adjusted to align the center line thereof with the design center line and ensure smoothness, no distortion and no stretching in the entire length direction.
[0071] In an alternative embodiment, the water stop gate 3 is hoisted and installed by hoisting equipment, so that the gate is slowly and smoothly sunk, the indentation of the water stop is checked in the sunk state, the position is confirmed to be correct and no abnormality, and finally the gate is seated on the guide sill 4, and then the lifting lugs pre-installed on the water stop gates 3 on the inner and outer sides of the gate 2 are connected together with the gate pier 1 or the gate 2 through a steel wire rope, so that the two water stop gates 3 are pre-tightened.
[0072] The above only describes the preferred embodiments of the present application and should not be used to limit the present application, and any modification, equivalent replacement and improvement within the spirit and principle of the present application should be included in the protection scope of the present application.
