Description

Technical Field

[0001] The present invention is a cofferdam device for water conservancy construction, belonging to the technical field of water conservancy. Background Art

[0002] During the construction of water conservancy projects, the cofferdam, as a temporary retaining structure, plays a crucial role. Its main function is to block water and soil from entering the designated construction area, reduce the interference of external factors on the project, and thus create conditions for the efficient development of operations such as foundation pit excavation and concrete pouring, effectively ensuring the project quality. In most cases, the cofferdam will be demolished after the project is completed. The currently common cofferdam device is of a double-wall type, generally consisting of an inner cylinder, a strengthening frame arranged at the outer end of the inner cylinder, an outer cylinder installed at the outer end of the strengthening frame, and a matching annular cutting edge. During construction, first, the cofferdam device is loaded onto a ship and transported to the designated construction site. Then, a crane is used to lift the cofferdam device from the ship and accurately place it into the water, so that the annular cutting edge can be smoothly inserted into the bottom of the water to complete the installation of the cofferdam device. Then, the water inside the cofferdam device is pumped out to expose the bottom of the water, providing a working surface for subsequent underwater construction inside the cofferdam. During the actual construction process, when weather conditions such as storms occur, it is extremely easy to cause water level fluctuations in the construction water area, generating phenomena such as water waves. These water level changes will generate a strong impact force on the cofferdam device, greatly increasing the risk of the cofferdam tilting, and further leading to potential leakage between the cofferdam and the bottom of the water. At the same time, the splashing water generated by the impact is also easy to enter the inner cylinder, interfering with the normal progress of the construction and having an adverse impact on the effect and quality of the cofferdam construction.

[0016] Example 1: As Figures 1 - 8 shown, a water conservancy construction cofferdam device is provided, including: outer cylinder 1, reinforcing frame 4 is arranged on the inner wall of outer cylinder 1. Through reinforcing frame 4, outer cylinder 1 is connected to inner cylinder 5, and inner cylinder 5 is installed on the inner wall of reinforcing frame 4.

Inner cylinder 5, reinforcing frame 4 and outer cylinder 1 are used in combination to form a double-wall cofferdam structure. Then, annular cutting edge 11 connected to the lower end of outer cylinder 1 is communicated and arranged on the lower end of inner cylinder 5. Through annular cutting edge 11, it is used to assist the double-wall cofferdam structure to insert into the bottom of the water. And movable cylinder 3 is attached to the outer end of the upper part of outer cylinder 1. Through movable cylinder 3, it provides an installation carrier for components such as annular airbag 7. Then, a plurality of auxiliary plates 31 whose outer end faces coincide with the outer end face of outer cylinder 1 are equidistantly installed on the upper end of outer cylinder 1. Through auxiliary plate 31, it provides a processing carrier for second chute 36; On the outer end faces of a plurality of auxiliary plates 31, second chutes 36 extending to the lower ends of auxiliary plates 31 are recessed inward. On the outer end face of outer cylinder 1, a plurality of first chutes 12 extending to the upper end of outer cylinder 1 are recessed inward. And a plurality of first chutes 12 are respectively communicated with the lower ends of a plurality of second chutes 36. The cross-sections of first chute 12 and second chute 36 are both T-shaped. First chute 12 and second chute 36 are used in combination to provide a channel for the movement of slider 34. A plurality of sliders 34 with a convex cross-section are equidistantly installed on the inner wall of movable cylinder 3. And a plurality of sliders 34 are respectively slidably connected in a plurality of first chutes 12. A plurality of sliders 34 are used in combination to guide the movement of movable cylinder 3. And a plurality of round rods 35 passing through and slidably connected to sliders 34 are equidistantly arranged between the inner bottom end of first chute 12 and the inner top end of second chute 36. A plurality of round rods 35 are used in combination to guide the movement of slider 34; A plurality of connecting rods 37 alternately arranged with the round rod 35 are equidistantly arranged on the upper end of the slider 34, and the upper ends of the plurality of connecting rods 37 all penetrate through the second sliding groove 36 and extend out of the upper side of the auxiliary plate 31. The plurality of connecting rods 37 are used in cooperation to connect the slider 34 and the connecting plate 372, and the lower end of the connecting plate 372 located on the upper side of the auxiliary plate 31 is connected to the upper ends of the plurality of connecting rods 37. Through the auxiliary plate 31, an installation carrier is provided for the hanging ring 371, and then the hanging ring 371 is installed on the middle part of the upper end of the connecting plate 372. Through the hanging ring 371, it is used to assist in the hoisting operation.

[0017] The annular airbag 7 is installed on the outer end of the movable cylinder 3. Through the annular airbag 7, the movable cylinder 3 and the functional cylinder 2 are connected. The honeycomb rubber ring 71 is filled in the annular airbag 7. The honeycomb rubber ring 71 and the annular airbag 7 are used in cooperation for buffering operations. Then, the functional cylinder 2 extending to the upper side of the outer cylinder 1 is arranged on the outer end of the annular airbag 7. Through the functional cylinder 2, it is used to block water waves. The arc-shaped cylinder 21 arranged with a narrow lower part and a wide upper part is connected and installed on the upper end of the functional cylinder 2. Through the arc-shaped cylinder 21, water is prevented from entering the inner cylinder 5. A plurality of first grooves are formed by inward depressions on the outer end surface of the functional cylinder 2, and a plurality of second grooves are formed by inward depressions on the outer end surface of the arc-shaped cylinder 21 facing outward. And the plurality of second grooves are respectively communicated with the upper ends of the plurality of first grooves. The plurality of first grooves and the plurality of second grooves are used in cooperation to make the outer end surface of the functional cylinder 2 and the outer end surface of the arc-shaped cylinder 21 both be wavy, so as to disperse the impact force generated by the water waves on the outer end surface of the functional cylinder 2, effectively reducing the impact strength.

[0018] A plurality of first plates 32 located outside the annular airbag 7 are equidistantly and movably installed on the inner wall of the functional cylinder 2, and a plurality of second plates 33 located outside the annular airbag 7 are equidistantly and movably arranged on the outer end of the movable cylinder 3. And the other ends of the plurality of second plates 33 are respectively movably connected to the other ends of the plurality of first plates 32. And the first plate 32 and the connected second plate 33 form a V-shaped structure. The plurality of first plates 32 and the plurality of second plates 33 are used in cooperation to make a rigid movable connection between the functional cylinder 2 and the movable cylinder 3.

[0019] During construction, first place the structure formed by components such as the inner cylinder 5, the reinforcing frame 4, the outer cylinder 1, and the functional cylinder 2 on the ship, then use the ship to transport the structure to the required position, then assemble the lifting part on the crane with the plurality of hanging rings 371, and then use the crane to move the plurality of hanging rings 371 upward, thereby making the plurality of connecting plates 372 move upward, so that the plurality of connecting rods 37 move upward, and further making the plurality of sliders 34 respectively move upward along the plurality of sliding channels formed by the first sliding groove 12 and the second sliding groove 36, so that the movable cylinder 3 moves upward, and with the assistance of the plurality of first plates 32 and the plurality of second plates 33, the annular airbag 7 and the functional cylinder 2 move upward to the limit position; At this time, the upper end of the slider 34 contacts the inner top end of the second chute 36. Then, use a crane to lift the structure from the ship, move the lifted structure to the required water surface, then place the structure into the water, and insert the annular cutting edge 11 into the bottom of the water, thus completing the installation of the structure. During the installation process, components such as the annular airbag 7 are always above the water surface, avoiding the interference of buoyancy formed by components such as the annular airbag 7 in the water during installation, effectively reducing the probability of the annular cutting edge 11 not being inserted in place during installation, effectively ensuring the construction effect and quality of the cofferdam, and having high stability; After the construction is completed, disassemble the lifting part on the crane from the multiple hanging rings 371, and under the action of the self-weights of components such as the movable cylinder 3, the auxiliary cylinder 113, and the annular airbag 7, move downward. Then, the lower and middle parts of components such as the movable cylinder 3, the auxiliary cylinder 113, and the annular airbag 7 enter the water. Then, pump out the water in the inner cylinder 5, and then the bottom of the water in the inner cylinder 5 is exposed. Then, carry out relevant construction on the bottom of the water in the inner cylinder 5; During the construction process, if the water environment changes such as water waves due to factors such as storms, the waves formed on the water surface will impact the end face of the functional cylinder 2 facing the wave direction, and then apply an impact force to the assembly formed by the annular airbag 7 and the honeycomb rubber ring 71, causing the assembly to deform, and then generating an elastic force. Thus, use the elastic force to buffer the impact force received by the functional cylinder 2, realizing the buffering of the impact force generated due to the water level change factor, effectively reducing the probability of the structure formed by components such as the inner cylinder 5, the strengthening frame 4, and the outer cylinder 1 tilting, effectively reducing the probability of leakage, effectively ensuring the construction effect and quality of the cofferdam, and having high stability; At the same time, due to water buoyancy, the annular airbag 7 and the honeycomb rubber ring 71 move up and down with the water level change, and then the functional cylinder 2 moves up and down with the water level change, so that the arc-shaped cylinder 21 moves up and down with the up and down movement of the functional cylinder 2, realizing the blocking of the splashing water generated due to the impact, effectively reducing the probability of water entering the inner cylinder 5, effectively ensuring the construction effect and quality of the cofferdam. At the same time, the up and down movement of the annular airbag 7 and the honeycomb rubber ring 71 will cause the movable cylinder 3 to move up and down with the water level change, so that the multiple sliders 34 move upward along the multiple sliding channels formed by the first chute 12 and the second chute 36 respectively, and then guide the movement of the movable cylinder 3. With the assistance of the multiple first plates 32 and the multiple second plates 33, the movable cylinder 3 and the functional cylinder 2 move up and down synchronously.

[0020] Embodiment 2: In water construction, the double-wall cofferdam structure plays an important role. The structure is composed of inner tube 5, reinforcement frame 4 and outer tube 1, and at the same time, with the help of movable tube 3, annular airbag 7, honeycomb rubber ring 71, auxiliary tube 113 and arc tube 21, the annular airbag 7 and honeycomb rubber ring 71 can effectively buffer the impact caused by water level changes, while the auxiliary tube 113 and arc tube 21 can effectively block the splashing water caused by the impact. This whole set of design greatly reduces the possibility of tilting of the main structure composed of inner tube 5, reinforcement frame 4 and outer tube 1, significantly reduces the risk of leakage, and creates a relatively stable and safe working environment for water construction. However, in actual application, affected by factors such as water waves, the assembly formed by the movable cylinder 3, the annular airbag 7, the honeycomb rubber ring 71, the auxiliary cylinder 113 and the arc cylinder 21 moves up and down. This unstable state has brought great obstacles to the construction personnel's entry and exit operations inside and outside the inner cylinder 5. During the entry and exit process, the construction personnel need to always deal with the movement of the components. If they are not careful, safety accidents such as slips and bumps may occur, which not only endangers the lives of the personnel, but also seriously affects the overall effect and efficiency of the cofferdam construction.

[0021] In order to solve the above problems, Figure 1 , Figure 2 , Figure 9 and Figure 10 As shown, a plurality of second pedals 64 are equidistantly installed between two second hollow rods 65 located in the inner tube 5 and extending out of the upper side of the inner tube 5. The plurality of second pedals 64 are used in conjunction with the plurality of second hollow rods 65 for climbing operations, and a plurality of fixing rods 66 are equidistantly arranged between the second hollow rods 65 and the inner tube 5. The plurality of fixing rods 66 are used in conjunction with each other to securely install the second hollow rods 65 and the inner tube 5. Then, a first shaft 62 extending outward from the two second hollow rods 65 and located on the upper side of the second pedals 64 is rotatably connected between the two second hollow rods 65. The first shaft 62 is used to rotatably connect the first hollow rod 6 and the second hollow rod 65. The first hollow rods 6 extending out of the upper sides of the two arc-shaped cylinders 21 on the outer sides of the two second hollow rods 65 are symmetrically arranged at the outer ends of the first shaft 62. The two first hollow rods 6 are used in cooperation to provide an installation carrier for the first pedal 61. A plurality of first pedals 61 located above the second hollow rods 65 are equidistantly installed between the two first hollow rods 6. The plurality of first pedals 61 and the two first hollow rods 6 are used in cooperation for climbing operations. Then, two first protection members are respectively arranged at the outer ends of the upper parts of the two first hollow rods 6. Through the first protection members, the arc-shaped cylinders 21 are protected. The first protection members can be rubber strips 67. The transverse part of the lifting column 68 with a T-shaped cross-section located above the first protection member is installed at the outer end of the first hollow rod 6. Through the lifting column 68, the first hollow rod 6 is lifted. Then, two second protection members are respectively arranged at the outer ends of the vertical parts of the two lifting columns 68. Through the second protection members, the lifting columns 68 are protected. The second protection members can be rubber pads; The third shaft 655 passing through the uppermost second pedal 64 is rotatably connected between the two second hollow rods 65. Through the third shaft 655, an installation carrier is provided for the fifth gear 654. The fixing part of the driving device located below the first hollow rod 6 and with an output shaft connected to the third shaft 655 is installed at the outer end of one second hollow rod 65 facing outwards. Through the driving device, the third shaft 655 is driven to rotate. The driving device can be the second motor 63. Then, two second shafts 653 are respectively rotatably connected inside the two second hollow rods 65. Through the second shafts 653, an installation carrier is provided for the fourth gears 652. The two fourth gears 652 are respectively arranged at the outer ends of the two second shafts 653. Through the fourth gears 652, the third gear 651 is rotated. Then, the two fifth gears 654 respectively located inside the two second hollow rods 65 are symmetrically installed at the outer end of the third shaft 655, and the two fifth gears 654 are respectively engaged with the lower ends of the two fourth gears 652. Through the fifth gears 654, the fourth gears 652 are rotated. The two third gears 651 respectively located inside the two second hollow rods 65 are symmetrically arranged at the outer end of the first shaft 62, and the two fourth gears 652 are respectively engaged with the lower ends of the two third gears 651. The two third gears 651 are used in cooperation to rotate the first shaft 62.

[0022] When in use, the second motor 63 is started first, and then the third shaft 655 is driven to rotate, so that the two fifth gears 654 are rotated. Since the two fifth gears 654 are respectively meshed with the lower ends of the two fourth gears 652, the rotation of the two fifth gears 654 will cause the two fourth gears 652 to rotate. Since the two fourth gears 652 are respectively meshed with the lower ends of the two third gears 651, the rotation of the two fourth gears 652 will cause the two third gears 651 to rotate, and then the first shaft 62 is rotated, so that the two first hollow rods 6 are rotated, and then the multiple first pedals 61, the two rubber strips 67, the two lifting columns 68 and the rubber pad are rotated, so that the two rubber strips 67 are in contact with the upper end of the arc tube 21. The first shaft 62 continues to rotate, thereby applying downward pressure to the arc tube 21, so that the functional tube 2, the annular airbag 7, the movable tube 3 and other components move downward, and the two rubber pads are in contact with the water platform, so that the first hollow rod 6 is lifted by the lifting column 68, and then the construction personnel climb on the climbing structure formed by the two first hollow rods 6, multiple first pedals 61, two second hollow rods 65 and multiple second pedals 64 and other components, so that the construction personnel can enter and exit the inner tube 5 inside and outside, and realize mechanical downward pressure on the arc tube 21, the functional tube 2, the annular airbag 7, the movable tube 3 and other components, effectively avoiding the arc tube 21 and other components from moving up and down under the action of water buoyancy and hindering the construction personnel from entering and exiting the inner tube 5 inside and outside, effectively ensuring the cofferdam construction effect and efficiency, and high safety.

[0023] Embodiment 3: In the process of water construction, the double-wall cofferdam structure shoulders a vital mission. Its main structure is composed of an inner tube 5, an outer tube 1 and a reinforcing frame 4 that plays a stabilizing role. In addition, the movable tube 3, annular airbag 7, honeycomb rubber ring 71, auxiliary tube 113 and arc tube 21 work together to build a protection system. When encountering the impact force caused by water level changes, the annular airbag 7 and the honeycomb rubber ring 71 can fully play a buffering role and effectively weaken the impact force. The auxiliary tube 113 and the arc tube 21 can block the splashing water caused by the impact and reduce the interference with the construction area. In addition, the annular blade foot 11 at the bottom of the structure is designed to firmly install the main structure on the bottom of the water, further enhance the overall stability, and create a relatively safe and stable working environment for water construction. However, in actual application scenarios, the cofferdam structure still faces some challenges. When the bottom soil of the construction area is relatively hard, the annular blade foot 11 is difficult to effectively insert into the bottom of the water, causing the main structure to be easily tilted under the action of external forces such as water flow. This tilt may not only cause leakage problems after the main structure is installed, seriously affecting the effect and quality of the cofferdam construction, but also significantly reduce the overall stability of the structure.

Through the annular gear 1191, the auxiliary ring 1194 rotates, and then the rotating gear 1192 located in the annular groove 1193 and meshing with the inner wall of the annular gear 1191 is installed on the lower end of the rotating shaft 119. Through the rotating gear 1192, the annular gear 1191 rotates; The first gear 111 is installed on the outer end of the annular cutting edge 11. Through the first gear 111, a plurality of second gears 112 rotate synchronously, and a plurality of movable plates 116 located below the outer cylinder 1 are slidably connected to the outer end of the outer cylinder 1 at equal intervals. Through the movable plate 116, a mounting carrier is provided for the insertion rod 115. Then, a plurality of insertion rods 115 are respectively arranged at the lower ends of a plurality of movable plates 116. The plurality of insertion rods 115 are used in cooperation for auxiliary fastening operations, and a plurality of auxiliary cylinders 113 are respectively threadedly connected to the outer ends of a plurality of insertion rods 115. Through the auxiliary cylinders 113, the insertion rods 115 move up and down. Then, a plurality of fixing plates 114 respectively rotatably connected to the outer ends of a plurality of auxiliary cylinders 113 are arranged at equal intervals on the outer end of the outer cylinder 1. Through the fixing plate 114, a mounting carrier is provided for the auxiliary cylinder 113, and a plurality of second gears 112 located below the fixing plate 114 and respectively installed at the outer ends of a plurality of auxiliary cylinders 113 are meshed with the outer end of the first gear 111 at equal intervals.

[0025] During construction, first use a ship to transport the structure formed by components such as the inner cylinder 5, the strengthening frame 4, the outer cylinder 1, and the functional cylinder 2 to the required position. Then use a crane to lift components such as the movable cylinder 3, the annular airbag 7, and the auxiliary cylinder 113 to the extreme position, so that components such as the annular airbag 7 are always above the water surface during the installation process. Then lift the structure from the ship and move the lifted structure to the required water surface. Then place the structure into the water. When the annular cutting edge 11 contacts the bottom of the water, start the first motor 117, thereby driving the rotation of the rotating shaft 119, and then making the rotating gear 1192 rotate. Since the rotating gear 1192 meshes with the annular gear 1191, the rotation of the rotating gear 1192 will cause the annular gear 1191 to rotate, and then make the auxiliary ring 1194 rotate, thereby making the annular cutting edge 11 rotate, and then assisting the operation of inserting the annular cutting edge 11 into the bottom of the water; At the same time, during the rotation of the annular cutting edge 11, the first gear 111 will rotate synchronously. Since the first gear 111 meshes with a plurality of second gears 112, the rotation of the first gear 111 will cause the plurality of second gears 112 to rotate synchronously, thereby making the plurality of auxiliary cylinders 113 rotate synchronously. Since the auxiliary cylinder 113 is threadedly connected to the insertion rod 115, the rotation of the auxiliary cylinder 113 will simultaneously make the insertion rod 115 move downward, and then make the insertion rod 115 insert into the bottom of the water, realizing multi-point fastening of the installation of the structure formed by components such as the inner cylinder 5, the strengthening frame 4, and the outer cylinder 1, effectively reducing the probability of leakage and other problems due to factors such as shaking, and effectively ensuring the construction effect and quality of the cofferdam, with high stability; After the construction is completed, disassemble the lifting part on the crane from a plurality of hanging rings 371, and under the action of the own weights of components such as the movable cylinder 3, the auxiliary cylinder 113, and the annular airbag 7, move downward, so that the middle and lower parts of components such as the movable cylinder 3, the auxiliary cylinder 113, and the annular airbag 7 enter the water. Then pump out the water in the inner cylinder 5, thereby exposing the bottom of the water in the inner cylinder 5, and then carry out relevant building construction on the bottom of the water in the inner cylinder 5.
