Description

Technical Field

[0001] The present invention relates to the technical field of water-related engineering, and in particular to an underwater barrier curtain and an installation method thereof. Background Art

[0002] With the rapid development of construction technology, the construction of various water-related projects near seas and lakes is increasing. Drainage piles and floating steel platforms are commonly used to achieve the purpose of water-based construction. However, the construction process inevitably affects or even damages the water body and its surrounding environment. Furthermore, encountering unfavorable underwater silt layers can affect construction safety and convenience. Therefore, how to reduce and control the spread of construction waste pollution while developing waterfront buildings and water-based buildings, and how to efficiently construct safe and reliable hydraulic structures, has become a difficult problem that concerns the world.

[0003] Underwater barrier curtains are the latest application in water pollution control. While previously, much attention was paid to oil contamination on the surface of water bodies, recent incidents of factory sewage system accidents and construction projects on the water surface often lead to contamination within the water. Traditional anti-pollution measures only block surface pollution, failing to isolate pollutants suspended within the water.

[0004] Underwater barrier curtains hold great promise for treating water pollutants, addressing both existing silt and water pollutants introduced during construction. Waters protected by these curtains can effectively prevent further spread of pollutants, protecting the waters and contributing to environmental protection and significant social benefits.

[0005] However, the current underwater barrier curtain has a complex structure and low construction efficiency. In addition, the deployment length and splicing width of the barrier curtain cannot be adjusted, and it cannot adapt to different water depths, different underwater landforms and different barrier conditions. Summary of the Invention

[0006] The purpose of the present invention is to overcome the defects and shortcomings of the prior art and provide an underwater partition curtain with a simple structure, which can simplify the operation process, improve construction efficiency, and adjust the unfolded length and splicing width of the underwater partition curtain to adapt to different water depths, different underwater landforms and different separation conditions.

[0012] Furthermore, two rows of holes arranged at equal intervals are provided on the left and right ends of each partition curtain, and the two holes in the same row of the same underwater partition curtain are respectively connected to the anchoring steel bars through spring buckles or restraint belts.

[0013] Furthermore, the spacer curtain is rectangular in shape, 20 meters in length, and is made of polyester woven canvas.

[0014] Furthermore, a warning light and a reflective strip are installed on the top of the anchoring steel bar, and a reflective strip is attached to the buoy.

[0015] Furthermore, the float is a closed hollow cylinder, and hexagonal grooves are provided at both ends of the float, and the grooves match the hexagonal outer wall surfaces of the rotating handle and the fixed handle.

[0016] Furthermore, the fixed handle includes a fixed block and a fixed iron chain, one end of the fixed iron chain is connected to the fixed block, and the other end is connected to a spring buckle.

DETAILED DESCRIPTION

[0044] The present invention will be described in further detail below with reference to the embodiments and drawings, but the embodiments of the present invention are not limited thereto.

[0045] Example 1

[0046] like Figure 1 、 2 As shown in Figure 3, an underwater partition curtain comprises a plurality of partition curtains 3, a buoy 1, a horizontal bar 4 and a counterweight rod 32. The plurality of partition curtains are arranged at equal intervals, and a row of holes 31 arranged at equal intervals are provided on the left and right ends of each partition curtain, and the hole spacing height is 10 cm, that is, four holes are arranged on the left and right ends between two adjacent partition curtains, and the diameter of the holes is 19 mm. The partition curtain is rectangular in shape and 20 meters in length. The material of the partition curtain is polyester (PET) woven canvas. A horizontal bar is provided between two adjacent partition curtains, and the horizontal bar is connected to the partition curtain by bolts or rivets. The horizontal bar is used to stabilize the partition curtain. Steel components 2 are provided at both ends of the horizontal bar, and the steel component and the horizontal bar are connected by welding. Bolt holes 21 are provided on the four corners of the steel component, which is fixed between two adjacent partition curtains by bolts or rivets. A connecting hole 22 is provided at the center of the steel component. A counterweight rod is provided at the lower end of the bottommost partition curtain. The counterweight rod can be an iron chain, a metal bar, concrete or other heavy rods, so that the partition curtain can sink to the bottom of the water by itself.

[0047] The buoy 1 is a closed hollow cylinder that can be made of polyethylene, polyurethane foam, or copolymer foam. The topmost separator curtain is wound around the buoy and can be rolled outside the buoy by rotating the buoy around its axis. Hexagonal grooves 11 are provided on both sides of the buoy. Figure 4 As shown, the rotating handle 5 is Z-shaped, and its cross-section is hexagonal and its size corresponds to the groove. Figure 5 As shown, the fixed handle 6 includes a fixed block 61 and a fixed iron chain 62. The fixed block is a hexagonal column with a hexagonal cross-section corresponding in size to the groove. The end of the fixed iron chain 62 is connected to a stainless steel spring buckle. When the underwater barrier curtain needs to be deployed, the rotating handle is inserted into the groove and the buoy is rotated to deploy the barrier curtain. When the barrier curtain reaches the required length or the bottom of the barrier curtain reaches the bottom of the water, the rotating handle is removed and the fixed handle is inserted into the groove. The fixed iron chain of the fixed handle secures the eyelet at the top of the deployed barrier curtain.

[0048] like Figure 6 As shown, when two underwater barrier curtains are connected, anchor steel bars 7 are set between the two adjacent underwater barrier curtains. In this embodiment, the two adjacent underwater barrier curtains are aligned, that is, the first underwater barrier curtain 34 is aligned with the second underwater barrier curtain 33. Figure 7As shown, at the connection point between the first and second underwater barrier curtains, a shackle 8 is inserted through the connection hole of the second steel member 23 of the first underwater barrier curtain and the connection hole of the first steel member 26 of the second underwater barrier curtain, and then connected to the anchor steel bar. Similarly, a shackle 8 is inserted through the connection hole of the fourth steel member 25 of the first underwater barrier curtain and the connection hole of the third steel member 24 of the second underwater barrier curtain, and then connected to the anchor steel bar. The upper and lower shackles are connected by a first connecting rod 10. The first connecting rod has sleeves at both ends to accommodate the upper and lower shackles and lock them with bolts. The first connecting rod increases the vertical stability of the underwater barrier curtain.

[0049] You can use a 16mm diameter nylon rope according to Figure 6 The connection method is to connect the holes at the connection position of the first underwater barrier curtain and the second underwater barrier curtain one by one. Figure 8 、 9 As shown, a spring buckle 92 or a disposable restraint belt 93 can also be used to connect the holes of two adjacent underwater partition curtains to ensure that the positions of the two underwater partition curtains do not deviate.

[0050] The installation process for the underwater barrier curtain in this embodiment is as follows: a floating platform is established above water, and the underwater barrier curtain to be installed is placed on the construction platform. The first anchoring bar is used to locate the position of the first underwater barrier curtain above water, pre-buried at least 1 meter. Rotating handles are installed in grooves on both sides of the first underwater barrier curtain and rotated to continuously unfold the curtain. At the same time, shackles are used to connect the steel structure and the anchoring bar at the end of the curtain closest to the anchoring bar. Spring hooks or disposable restraints are used to connect the eyelets and the anchoring bar. A first connecting rod is also used to connect the upper and lower adjacent shackles. Once a hole or steel structure is connected, the rotating handle is rotated to unfold the curtain and allow the connected section to sink. Once the curtain reaches the bottom of the water, the rotating handle is removed and the fixing handle is inserted into the groove of the buoy. A fixing chain is then connected to the uppermost eyelets at both ends of the curtain to secure the curtain's extended length. The end of the curtain away from the anchoring bar is placed on the construction platform frame, awaiting connection to the next adjacent underwater barrier curtain.

[0051] Secure the second anchoring steel bar at the connection point between the previous underwater curtain and the next adjacent curtain, ensuring that the required embedded depth is met. Transport the next curtain to the designated location, aligning it with the first. At the connection point between the first and second curtains, insert a shackle through the steel member connection holes of the first curtain and the second curtain, and connect it to the anchoring steel bar. Use the first connecting rod to connect the upper and lower adjacent shackles; use a rope, spring hook, or disposable restraint belt to connect the eyelets of the two adjacent curtains.

[0052] Once a hole or steel structure is connected, the rotary handle is turned to deploy the next underwater curtain, allowing the connected portion of the adjacent curtain to sink. Once the curtain reaches the bottom, the rotary handle is pulled out and the fixed handle is inserted into the buoy groove. The fixed chain is connected to the top hole of the next curtain to secure the next curtain's deployment length. The end of the next curtain, away from the anchoring rebar, is placed on the construction platform frame, awaiting connection to the remaining adjacent curtains. This process is repeated until all curtains have been deployed and the final curtain is connected to the final anchoring rebar.

[0053] In this embodiment, the anchoring steel bars are ribbed steel bars. Warning lights and reflective strips can be installed on the top of the anchoring steel bars. After the underwater barrier curtain is fixed, reflective strips can be attached to the buoy to remind ships to avoid it at night. The underwater barrier curtain of this embodiment has good connection sealing and is suitable for use in waters with high anti-fouling or barrier requirements, and the underwater barrier curtain protective belt does not open. The underwater barrier curtain is prefabricated in the factory. The finished product is a barrier curtain wrapped around the buoy, and the holes, steel components, cross bars, and counterweight rods of the underwater barrier curtain are all installed.

[0054] Example 2

[0055] like Figure 10 As shown, in this embodiment, each piece of the underwater barrier curtain is provided with two rows of holes 31 arranged at equal intervals at the left and right ends, and the steel components provided at both ends of the horizontal bar are provided with two connecting holes 22. Other parts not mentioned are the same as those in the first embodiment.

[0056] like Figure 11 As shown, when two underwater barrier curtains are connected, anchoring steel bars 7 are provided between adjacent underwater barrier curtains. In this embodiment, the adjacent underwater barrier curtains are staggered, i.e., the first underwater barrier curtain 34 is staggered with the second underwater barrier curtain 33. To ensure a tight connection between the steel components or holes of adjacent underwater barrier curtains and to reduce the size of the hole at the connection between the first and second underwater barrier curtains, the adjacent underwater barrier curtains are staggered by 20 mm.

[0057] like Figure 12As shown, at the connection position between the first underwater barrier curtain and the second underwater barrier curtain, a shackle 8 is used to pass through the two connection holes 22 of the second steel member 23 on the first underwater barrier curtain and connect to the anchoring steel bar 7; a shackle is used to pass through the two connection holes of the fourth steel member 25 on the first underwater barrier curtain and connect to the anchoring steel bar, and a second connecting rod 100 is used to connect the two shackles. Similarly, a shackle is used to pass through the two connection holes 22 of the first steel member 26 on the second underwater barrier curtain and connect to the anchoring steel bar; a shackle is used to pass through the two connection holes of the second steel member 24 on the second underwater barrier curtain and connect to the anchoring steel bar, and a second connecting rod 100 is used to connect the two shackles. The anchoring steel bar in this embodiment adopts plain round steel bar, and may also adopt section steel or prefabricated rod.

[0058] like Figure 13 As shown, a spring hook 92 is inserted through the two eyelets 31 of the first underwater barrier curtain and connected to the anchoring steel bar 7. Similarly, a spring hook 92 is inserted through the two eyelets 31 of the second underwater barrier curtain and connected to the anchoring steel bar 7. In this embodiment, since the underwater barrier curtain is connected only to the anchoring steel bar, the layout of the underwater barrier curtain protection belt can be adjusted after installation by pulling out the anchoring steel bar and moving the anchoring steel bar, facilitating project adjustments. The underwater barrier curtain protection belt can also be quickly and conveniently opened by completely pulling out the anchoring steel bar to meet navigation requirements.

[0059] The installation process for the underwater barrier curtain in this embodiment is as follows: a floating platform is established above water, and the underwater barrier curtain to be installed is placed on the construction platform. The first anchoring bar is used to locate the position of the first underwater barrier curtain above water, pre-buried at least 1 meter. Rotating handles are installed in grooves on both sides of the first underwater barrier curtain and rotated to continuously unfold the barrier curtain. At the same time, shackles are used to connect the steel structure and the anchoring bar at the end of the underwater barrier curtain closest to the anchoring bar. Spring hooks or disposable restraints are used to connect the eyelets and the anchoring bar. A second connecting rod is used to connect the upper and lower adjacent shackles. Once a hole or steel structure is connected, the rotating handle is rotated to unfold the barrier curtain and allow the connected section to sink. Once the barrier curtain reaches the bottom of the water, the rotating handle is removed and the fixing handle is inserted into the groove of the buoy. A fixing chain is connected to the uppermost eyelets at both ends of the barrier curtain to fix the extended length of the barrier curtain. The end of the barrier curtain away from the anchoring bar is placed on the construction platform frame, awaiting connection to the next adjacent underwater barrier curtain.

[0060] Secure the second anchoring rebar at the point where the previous underwater curtain connects to the next adjacent curtain, ensuring a predetermined depth. Transport the next curtain to the desired location. Install the rotary handles in the grooves on either side of the curtain and rotate them to continuously unfold the curtain. The first and second curtains rotate in opposite directions and overlap by the length of a steel member. Adjacent curtains are staggered, with the second anchoring rebar located between them. Pass a shackle through the two connection holes in the first curtain's steel member and connect to the anchoring rebar. Use a second connecting rod to connect the two adjacent shackles above and below the first curtain. Similarly, use a shackle to connect the second curtain to the anchoring rebar, and connect the two adjacent shackles above and below the first curtain using the second connecting rod. Pass a spring hook or disposable restraint strap through the two eyelets of the first and second curtains and connect to the anchoring rebar.

[0061] Once a hole or steel structure is connected, the rotary handle is turned to deploy the next underwater curtain, allowing the connected portion of the adjacent curtain to sink. Once the curtain reaches the bottom, the rotary handle is pulled out and the fixed handle is inserted into the buoy groove. The fixed chain is connected to the top hole of the next curtain to secure the extended length of the next curtain. The end of the next curtain, away from the anchor bar, is placed on the construction platform frame, awaiting connection to the remaining curtains. This process is repeated until all curtains have been deployed and the final curtain is connected to the final anchor bar.

[0062] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
