Description

Technical Field

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

[0002] During the construction of hydraulic engineering, 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 guaranteeing the project quality. In most cases, the cofferdam will be demolished after the project is completed.

[0003] 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, enabling the annular cutting edge to smoothly insert 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 within the cofferdam.

[0004] 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 then leading to potential leakage problems between the cofferdam and the bottom of the water. At the same time, the splashing water generated by the impact is also likely 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.

[0049] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0050] Embodiment 1: As Figures 1 - 8As shown in the figure, a water conservancy construction cofferdam device is provided, including: an outer cylinder 1, a reinforcing frame 4 is arranged on the inner wall of the outer cylinder 1. Through the reinforcing frame 4, the outer cylinder 1 is connected to the inner cylinder 5, and the inner cylinder 5 is installed on the inner wall of the reinforcing frame 4. Moreover, the upper end surfaces of the inner cylinder 5, the reinforcing frame 4, and the outer cylinder 1 coincide with each other. The inner cylinder 5, the reinforcing frame 4, and the outer cylinder 1 are used in cooperation to form a double-wall cofferdam structure. Then, an annular cutting edge 11 connected to the lower end of the outer cylinder 1 is communicated with the lower end of the inner cylinder 5. Through the annular cutting edge 11, it is used to assist the double-wall cofferdam structure to insert into the bottom of the water. The movable cylinder 3 is attached to the outer end of the upper part of the outer cylinder 1. Through the movable cylinder 3, it provides an installation carrier for components such as the annular airbag 7. Then, a plurality of auxiliary plates 31 whose outer end faces coincide with the outer end face of the outer cylinder 1 are equidistantly installed on the upper end of the outer cylinder 1. Through the auxiliary plates 31, it provides a processing carrier for the second chute 36;

[0051] On the outer end faces of a plurality of auxiliary plates 31, second chutes 36 extending to the lower ends of the auxiliary plates 31 are recessed inward. On the outer end face of the outer cylinder 1, a plurality of first chutes 12 extending to the upper end of the 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 the first chute 12 and the second chute 36 are both T-shaped. The first chute 12 and the second chute 36 are used in cooperation to provide a channel for the movement of the slider 34. A plurality of sliders 34 with a convex cross-section are equidistantly installed on the inner wall of the 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 cooperation to guide the movement of the movable cylinder 3. And a plurality of round rods 35 passing through the sliders 34 and slidably connected to the sliders 34 are equidistantly arranged between the inner bottom end of the first chute 12 and the inner top end of the second chute 36. A plurality of round rods 35 are used in cooperation to guide the movement of the slider 34;

[0052] A plurality of connecting rods 37 arranged alternately with the round rods 35 are equidistantly arranged on the upper ends of the sliders 34. And the upper ends of a plurality of connecting rods 37 all pass through the second chute 36 and extend above the auxiliary plate 31. A plurality of connecting rods 37 are used in cooperation to connect the slider 34 to the connecting plate 372. And the lower end of the connecting plate 372 located above the auxiliary plate 31 is connected to the upper ends of a plurality of connecting rods 37. Through the auxiliary plate 31, it provides an installation carrier for the hanging ring 371. Then, the hanging ring 371 is installed in the middle of the upper end of the connecting plate 372. Through the hanging ring 371, it is used to assist in the hoisting operation.

[0053] Install the annular airbag 7 on the outer end of the movable cylinder 3. Through the annular airbag 7, connect the movable cylinder 3 with the functional cylinder 2, and fill the honeycomb rubber ring 71 in the annular airbag 7. The honeycomb rubber ring 71 is used in conjunction with the annular airbag 7 for buffering operations. Then, set the functional cylinder 2 extending to the upper side of the outer cylinder 1 on the outer end of the annular airbag 7. Through the functional cylinder 2, it is used to block water waves. Connect the arc-shaped cylinder 21 arranged with a narrow lower part and a wide upper part to the upper end of the functional cylinder 2. Through the arc-shaped cylinder 21, prevent water from entering the inner cylinder 5. A plurality of first grooves are formed by inward depressions on the outer end face of the functional cylinder 2, and a plurality of second grooves are formed by inward depressions on the outer end face of the arc-shaped cylinder 21 facing outward. And the plurality of second grooves are respectively connected to the upper ends of the plurality of first grooves. The plurality of first grooves and the plurality of second grooves are used in conjunction with each other, making the outer end face of the functional cylinder 2 and the outer end face of the arc-shaped cylinder 21 both in a wavy shape, so as to disperse the impact force generated by the water waves on the outer end face of the functional cylinder 2, effectively reducing the impact strength.

[0054] Equidistantly and movably install a plurality of first plates 32 located outside the annular airbag 7 on the inner wall of the functional cylinder 2, and equidistantly and movably arrange a plurality of second plates 33 located outside the annular airbag 7 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 conjunction with each other, making a rigid movable connection between the functional cylinder 2 and the movable cylinder 3.

[0055] 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, and then use the ship to transport the structure to the required position. Then, assemble the lifting part on the crane with a plurality of hanging rings 371, and then use the crane to move the plurality of hanging rings 371 upward, and then move the plurality of connecting plates 372 upward, thereby moving the plurality of connecting rods 37 upward, and then moving the plurality of sliders 34 respectively upward along the sliding channels formed by a plurality of first chutes 12 and second chutes 36, so as to move the movable cylinder 3 upward. And with the assistance of the plurality of first plates 32 and the plurality of second plates 33, move the annular airbag 7 and the functional cylinder 2 upward to the limit position;

[0056] At this time, the upper end of the slider 34 contacts the inner top of the second chute 36. Then, use the crane to lift the structure from the ship, and move the hoisted structure to the required water surface, and 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. And during the installation process, components such as the annular airbag 7 are always above the water surface, realizing the avoidance of the buoyancy formed by components such as the annular airbag 7 in the water interfering with the 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;

[0057] After the construction is completed, the lifting part on the crane is disassembled from the multiple hanging rings 371, and it moves downward under the action of its own weight of components such as the movable cylinder 3, the auxiliary cylinder 113, and the annular airbag 7. Then, the lower parts of components such as the movable cylinder 3, the auxiliary cylinder 113, and the annular airbag 7 enter the water. Then, the water inside the inner cylinder 5 is pumped out, and then the bottom of the inner cylinder 5 is exposed. Then, relevant building construction is carried out on the bottom of the inner cylinder 5;

[0058] During the building construction process, if the corresponding water environment has water level 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. Then, an impact force is exerted on the component formed by the annular airbag 7 and the honeycomb rubber ring 71, causing the component to deform. Then, the component generates an elastic force, and the elastic force is used to buffer the impact force received by the functional cylinder 2, realizing the buffering of the impact force caused by water level change factors, effectively reducing the probability of the structure formed by components such as the inner cylinder 5, the reinforcing frame 4, and the outer cylinder 1 tilting, effectively reducing the probability of leakage occurrence, effectively ensuring the construction effect and quality of the cofferdam, and having high stability;

[0059] At the same time, due to the water buoyancy, the annular airbag 7 and the honeycomb rubber ring 71 move up and down with the water level change. Then, the functional cylinder 2 moves up and down with the water level change, and thus the arc-shaped cylinder 21 moves up and down with the functional cylinder 2 moving up and down, realizing the blocking of the splashing water caused by 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 causes the movable cylinder 3 to move up and down with the water level change. Then, the multiple sliders 34 move upward along the multiple sliding channels formed by the first sliding groove 12 and the second sliding groove 36 respectively, further guiding the movement of the movable cylinder 3, and 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.

[0060] Embodiment 2: In the water construction operation, the double-wall cofferdam structure plays an important role. This structure is composed of components such as the inner cylinder 5, the reinforcing frame 4, and the outer cylinder 1. At the same time, with the coordinated operation of the movable cylinder 3, the annular airbag 7, the honeycomb rubber ring 71, the auxiliary cylinder 113, and the arc-shaped cylinder 21, in the face of the impact force caused by the water level change, the annular airbag 7 and the honeycomb rubber ring 71 can effectively buffer, while the auxiliary cylinder 113 and the arc-shaped cylinder 21 can effectively block the splashing water caused by the impact. This whole set of designs greatly reduces the possibility of the main structure composed of the inner cylinder 5, the reinforcing frame 4, and the outer cylinder 1 tilting, significantly reduces the leakage risk, and creates a relatively stable and safe operation environment for the water construction.

[0061] However, in practical applications, 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 operation of construction workers entering and leaving the inner cylinder 5. During the process of entering and leaving, construction workers need to constantly deal with the movement of the assembly. A slight mistake may lead to safety accidents such as slipping and bumping, which not only endangers the lives of personnel but also seriously affects the overall effect and efficiency of the cofferdam construction.

[0062] To solve the above problems, as Figure 1 , Figure 2 , Figure 9 and Figure 10 shown, a plurality of second pedals 64 are equidistantly installed between two second hollow rods 65 located inside the inner cylinder 5 and extending above the upper side of the inner cylinder 5. The plurality of second pedals 64 are used in cooperation with the plurality of second hollow rods 65 for climbing operations. A plurality of fixing rods 66 are equidistantly arranged between the second hollow rods 65 and the inner cylinder 5. The plurality of fixing rods 66 are used in cooperation to firmly install the second hollow rods 65 and the inner cylinder 5. Then, a first shaft 62 extending outward from the two second hollow rods 65 and located above the second pedals 64 is rotatably connected between the two second hollow rods 65. Through the first shaft 62, the first hollow rod 6 and the second hollow rod 65 are rotatably connected;

[0063] Two first hollow rods 6 extending above the arc cylinder 21 and located outside 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 are used in cooperation with the two first hollow rods 6 for climbing operations. Then, two first protection members are respectively arranged at the outer upper ends of the two first hollow rods 6. Through the first protection members, the arc cylinder 21 is protected. The first protection member can be a rubber strip 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 member can be a rubber pad;

[0064] The third shaft 655 passing through the second pedal 64 at the uppermost side is rotatably connected between two second hollow rods 65. Through the third shaft 655, a mounting carrier is provided for the fifth gear 654, and the fixing part of the driving device located below the first hollow rod 6 and with its output shaft connected to the third shaft 655 is mounted on the outer end of one second hollow rod 65. Through the driving device, the third shaft 655 is driven to rotate. The driving device can adopt 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, a mounting carrier is provided for the fourth gears 652, and 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 mounted on 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. And 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.

[0065] During use, first start the second motor 63, which then drives the third shaft 655 to rotate, thereby causing the two fifth gears 654 to rotate. Since the two fifth gears 654 are respectively engaged 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. And since the two fourth gears 652 are respectively engaged 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, thereby rotating the first shaft 62, causing the two first hollow rods 6 to rotate, and then causing the multiple first pedals 61, the two rubber strips 67, the two lifting columns 68, and the rubber pads to rotate, so that both rubber strips 67 come into contact with the upper end of the arc-shaped cylinder 21.

[0066] Continue to rotate the first shaft 62, thereby applying a downward pressure to the arc-shaped cylinder 21, causing components such as the functional cylinder 2, the annular airbag 7, and the movable cylinder 3 to move downward, and causing the two rubber pads to contact the water platform. Then, the lifting columns 68 are used to lift the first hollow rods 6. Then, construction workers carry out climbing operations on the climbing structure formed by components such as the two first hollow rods 6, the multiple first pedals 61, the two second hollow rods 65, and the multiple second pedals 64, so that the construction workers can enter and exit the inner cylinder 5, realizing mechanical pressing on components such as the arc-shaped cylinder 21, the functional cylinder 2, the annular airbag 7, and the movable cylinder 3, effectively avoiding the upward and downward movement of components such as the arc-shaped cylinder 21 under the action of water buoyancy from hindering the construction workers from entering and exiting the inner cylinder 5, effectively ensuring the construction effect and efficiency of the cofferdam, and having high safety.

[0067] 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.

[0068] 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.

[0069] In order to solve the above problems, Figures 11 - 15 As shown, the mounting plate 118 located outside the auxiliary plate 31 and inside the movable cylinder 3 is mounted on the upper end of the inner cylinder 5, and the lower end of the mounting plate 118 is connected to the upper end of the outer cylinder 1. The mounting plate 118 is used to provide a mounting carrier for the first motor 117 and other components, and the rotating shaft 119 located in the reinforcing frame 4 is rotatably connected to the lower end of the mounting plate 118. The rotating gear 1192 is rotated through the rotating shaft 119, and then the fixed part of the first motor 117 whose output shaft is connected to the rotating shaft 119 is mounted on the upper end of the mounting plate 118. The rotating shaft 119 is driven to rotate through the first motor 117.

[0070] The auxiliary ring 1194 located at the lower side of the reinforcing frame 4 is installed on the upper end of the annular blade foot 11, and the auxiliary ring 1194 is slidably connected to the outer end of the inner tube 5 and the inner wall of the outer tube 1 respectively, and the upper end of the annular blade foot 11 is sealed and movably connected to the lower end of the inner tube 5 and the lower end of the outer tube 1 respectively, through the auxiliary ring 1194, a mounting carrier is provided for the annular blade foot 11, and an annular groove 1193 is formed on the upper end surface of the auxiliary ring 1194. Through the annular groove 1193, a mounting space is provided for components such as the annular gear 1191, and the annular gear 1191 is installed on the inner wall of the annular groove 1193 facing outwards, and the auxiliary ring 1194 is rotated through the annular gear 1191, and then the rotating gear 1192 located in the annular groove 1193 and meshed with the inner wall of the annular gear 1191 is installed on the lower end of the rotating shaft 119, and the annular gear 1191 is rotated through the rotating gear 1192;

[0071] The first gear 111 is installed on the outer end of the annular cutting edge 11. Through the first gear 111, multiple second gears 112 are synchronously rotated. Multiple 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 plates 116, an installation carrier is provided for the insertion rods 115. Then, multiple insertion rods 115 are respectively arranged at the lower ends of the multiple movable plates 116. The multiple insertion rods 115 are used in cooperation for auxiliary fastening operations. Multiple auxiliary cylinders 113 are respectively threadedly connected to the outer ends of the multiple insertion rods 115. Through the auxiliary cylinders 113, the insertion rods 115 move up and down. Then, multiple fixing plates 114 respectively rotatably connected to the outer ends of the multiple auxiliary cylinders 113 are arranged at equal intervals on the outer end of the outer cylinder 1. Through the fixing plates 114, an installation carrier is provided for the auxiliary cylinders 113. Multiple second gears 112 respectively installed at the lower sides of the fixing plates 114 at the outer ends of the multiple auxiliary cylinders 113 are meshed with the outer end of the first gear 111 at equal intervals. Through the second gears 112, the auxiliary cylinders 113 are rotated.

[0072] 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 move components such as the movable cylinder 3, the annular airbag 7, and the auxiliary cylinder 113 up to the limit 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;

[0073] At the same time, during the rotation of the annular cutting edge 11, the first gear 111 will be synchronously rotated. Since the first gear 111 meshes with multiple second gears 112, the rotation of the first gear 111 will cause the multiple second gears 112 to be synchronously rotated, thereby making the multiple auxiliary cylinders 113 rotate synchronously. Since the auxiliary cylinders 113 are threadedly connected to the insertion rods 115, the rotation of the auxiliary cylinders 113 simultaneously makes the insertion rods 115 move downward, and then makes the insertion rods 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, effectively ensuring the construction effect and quality of the cofferdam, and having high stability;

[0074] After the construction is completed, the lifting part on the crane is disassembled from the plurality of hanging rings 371, and it moves downward under the action of its own weight of components such as the movable cylinder 3, the auxiliary cylinder 113, and the annular airbag 7. Then, the lower parts of components such as the movable cylinder 3, the auxiliary cylinder 113, and the annular airbag 7 enter the water. Next, the water located in the inner cylinder 5 is pumped out, so that the bottom of the inner cylinder 5 is exposed. Then, relevant construction work is carried out on the bottom of the inner cylinder 5.

Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
