[0001] The present application relates to the technical field of concrete pipe construction, and in particular to a large-diameter concrete pipe joint mechanism for high-water-level strata. Background Art
[0002] Large-diameter concrete pipes in high-water-level strata usually refer to concrete pipes with a diameter of more than 1000mm. Concrete pipes are laid in geological environments with high groundwater levels or high surface water levels and in high-water-level strata. The pipe joints must have good waterproof properties to prevent groundwater leakage.
[0003] Usually, when laying large-diameter concrete pipes, they are laid by hoisting. During the laying process, two pipes are connected to each other by means of a socket connection, and waterproof material is wrapped around the outside of the socket end to ensure waterproof performance. However, in this socket connection process, when one pipe is hoisted and moved toward another stationary pipe, the waterproof material is first wrapped around the moving pipe at the same time. The moving pipe cannot guarantee coaxiality with the stationary pipe, and the waterproof material may move due to collision and friction during the connection process, and it is impossible to fully ensure that the waterproof material is wrapped in place; after the connection is completed, the waterproof material needs to be wrapped a second time, and the pipe cannot be moved, and the second wrapping cannot be guaranteed to be in place.

[0025] The following is combined with Figure 1-6 This application is described in further detail.
[0026] The embodiment of the present application discloses a large-diameter concrete pipe joint mechanism in a high-water-level stratum.
[0027] First, refer to Figure 4 , Figure 5 as well as Figure 6, the structure and installation method of the pipe 1 made of concrete in the prior art are explained. The pipe 1 is a stepped cylindrical structure, with a large diameter end being a receiving end 11 and a small diameter end being a plug end 12. The inner side of the receiving end 11 forms an annular stepped platform for the plug end 12 to be inserted. After the plug end 12 is inserted, an annular gap is formed for the sealing layer 2 to enter; the outer side of the receiving end 11 bulges outward, and the outer diameter of the receiving end 11 is larger than the outer diameter of the plug end 12 to ensure the structural strength after the two pipes 1 are connected; and usually, a slope 13 is formed on the outer side of the receiving end 11 close to the plug end 12 for demoulding.
[0028] When installing the pipeline 1, the pipeline 1 is hoisted in the groove. Before hoisting, a cushion block 14 is pre-placed in the groove to cushion the plug-in end 12 of the pipeline 1 to ensure the overall horizontal state of the pipeline 1, and then multiple pipelines 1 are hoisted in sequence. At this time, the entire middle part of the pipeline 1 is suspended.
[0029] After the first pipe 1 is hoisted into place, the second pipe 1 is hoisted. A sealing layer 2 is arranged outside the plug-in end 12 of the second pipe 1 . The sealing layer 2 enters into the receiving end 11 of the first pipe 1 as the second pipe 1 is hoisted.
[0030] However, in this socket-and-spigot method, during the socket-and-spigot process, when the second pipe 1 is hoisted and moved toward the first stationary pipe 1, the waterproof material (sealing layer 2) is first wrapped around the moving second pipe 1. The moving second pipe 1 cannot ensure coaxiality with the stationary first pipe 1 during the hoisting process, and the waterproof material (sealing layer 2) may move due to collision and friction during the socket-and-spigot process, and it is impossible to fully ensure that the waterproof material (sealing layer 2) is wrapped in place. After the socket-and-spigot process, the waterproof material needs to be wrapped a second time. Since the pipe 1 cannot move, it is also impossible to ensure that the second wrapping is in place.
[0031] Reference Figures 1 to 3 A large-diameter concrete pipe joint mechanism for high-water-level strata includes a joint frame 3 with one end detachably connected to a receiving end 11 of a first pipe 1 and a push ring 4 with an outer thread connected to the joint frame 3. The push ring 4 is used to be sleeved on a plug-in end 12 of a second pipe 1, and the end portion is used to abut against a sealing layer 2 filled between the two pipes 1.
[0032] When the plug-in end 12 of the second pipe 1 is plugged into the receiving end 11 of the first pipe 1, or after the plug-in end 12 of the second pipe 1 is plugged into the receiving end 11 of the first pipe 1, the sealing layer 2 on the plug-in end 12 of the second pipe 1 can be pushed forward by rotating the pushing ring 4, so that the sealing layer 2 enters inward and fills the gap between the two pipes 1, thereby improving the technical problem in the prior art that the waterproof material at the joint of the concrete pipe may move due to collision and friction during the connection process, and the waterproof material cannot be completely wound in place, resulting in poor waterproof effect.
[0033] Furthermore, other sealing materials may be abutted against the end of the propulsion ring 4 to form a second sealing ring layer, and the second sealing ring layer may be bonded by glue to improve the sealing effect.
[0034] Reference Figures 1 to 3 The joint frame 3 includes a clamping ring 31, at least three connecting frames 32 with one end detachably connected to the clamping ring 31, and at least three force screws 33. The clamping ring 31 is used to be coaxially sleeved on the first pipe 1, and the end thereof abuts against the side of the receiving end 11 of the first pipe 1 close to the plug-in end 12. Each connecting frame 32 and each force screw 33 are arranged in a one-to-one correspondence, and the force screw 33 is threadedly connected to the other end of the connecting frame 32. The force screw 33 is used to abut against the other side of the receiving end 11 of the first pipe 1, and the pushing ring 4 is threadedly connected to each connecting frame 32.
[0035] The connecting frames 32 are arranged at intervals around the pipeline 1 in the circumferential direction.
[0036] Specifically, the end of the clamping ring 31 abuts against the inclined surface 13 of the receiving end 11 of the first pipe 1 to ensure the coaxiality of the clamping ring 31 and the pipe 1 through the limitation of the inclined surface 13 .
[0037] The joint frame 3 is fixedly installed by simultaneously clamping the receiving end 11 of the first pipe 1 with the clamping ring 31 and a plurality of force screws 33 , so as to serve as a basis for the propulsion ring 4 to rotate in a thread and propel the sealing layer 2 .
[0038] The joint frame 3 further comprises a plurality of tightening screws 34, which are threadedly connected to the clamping ring 31, and the ends of the tightening screws 34 are used to press against the first pipe 1. By applying pressure toward the first pipe 1 by the tightening screws 34, the installation stability of the joint frame 3 is improved.
[0039] The clamping ring 31 includes at least two clamping arc plates 311, a plurality of connecting ears 312, and a plurality of first fasteners 313. The clamping arc plates 311 are connected in sequence to form a ring shape. The plurality of connecting ears 312 are arranged one by one at both ends of each clamping arc plate 311. The first fastener 313 is used to simultaneously connect two abutting connecting ears 312. The connecting frame 32 is detachably connected to the clamping arc plate 311. The first fastener 313 may be a bolt.
[0040] The clamping ring 31 is divided into at least two clamping arc plates 311 , which facilitates the assembly and disassembly of the clamping ring 31 .
[0041] The at least two clamping arc plates 311 can be two, three, four, etc. In the figure, the at least two clamping arc plates 311 are only shown as two, which are composed of two semicircular arc plates with an angle of 180°.
[0042] By providing the clamping arc plate 311 , it is convenient to assemble and disassemble the clamping arc plate 311 by suspending it from the middle of the pipeline 1 .
[0043] In the radial direction of the clamping ring 31 , the sum of the thickness of the clamping arc plate 311 and the length of the connecting ear 312 is lower than the thickness of the receiving end 11 of the pipe 1 , so that after the clamping ring 31 is assembled, the entire clamping ring 31 can be rotated smoothly.
[0044] The connecting frame 32 includes a fixing seat 321 with one end detachably connected to the clamping ring 31, a connecting rod 322 with one end connected to the fixing seat 321, and a connecting seat 323 with one end fixedly connected to the other end of the connecting rod 322. The pushing ring 4 is threadedly connected to multiple connecting seats 323.
[0045] Specifically, one end of the fixing seat 321 can be detachably connected to the clamping arc plate 311 of the clamping ring 31 by means of a snap connection, a threaded connection, etc. (not shown in the figure).
[0046] As one of the parallel ways, one end of the connecting rod 322 can be fixedly connected to the fixing seat 321 .
[0047] As a second parallel mode, one end of the connecting rod 322 can be slidably connected to the fixing seat 321, and at least two limiting nuts 3221 are threadedly connected to the connecting rod 322. The plurality of limiting nuts 3221 are respectively located on both sides of the fixing seat 321, and the limiting nuts 3221 abut against the fixing seat 321 to limit the sliding of the connecting rod 322. The connecting rod 322 is slidably connected to the fixing seat 321, so as to facilitate the adjustment of the position of the other end of the connecting frame 32 relative to the propulsion ring 4.
[0048] Reference Figures 1 to 3The propulsion ring 4 includes at least two propulsion arc plates 41, a plurality of fixing ears 42 and a plurality of second fasteners 43. The ends of each propulsion arc plate 41 are sequentially connected to form a ring and threadedly connected to the joint frame 3. The plurality of fixing ears 42 are arranged at both ends of each propulsion arc plate 41. The second fastener 43 is used to simultaneously connect two abutting fixing ears 42.
[0049] The propulsion ring 4 is divided into at least two propulsion arc plates 41, which is convenient for disassembling and assembling the propulsion ring 4. By providing the propulsion arc plates 41, it is convenient to disassemble and assemble the propulsion arc plates 41 by suspending them from the middle of the pipeline 1.
[0050] Specifically, the advancing arc plate 41 is threadedly connected to the connecting seat 323. The second fastener 43 may be a bolt.
[0051] In the radial direction of the propulsion ring 4, the sum of the thickness of the propulsion arc plate 41 and the length of the fixing ear 42 is lower than the thickness of the receiving end 11 of the pipeline 1. This facilitates the smooth disassembly and assembly of the propulsion arc plate 41 to the pipeline 1, and after the propulsion ring 4 is assembled, the entire propulsion ring 4 can be smoothly rotated.
[0052] The propulsion ring 4 is in the shape of a stepped shaft, and the inner side of one end of the propulsion arc plate 41 is used for coaxial sliding and rotational connection to the outer side of the plug end 12 of the second pipe 1. The plug end 12 of the second pipe 1 supports one end of the propulsion ring 4 to ensure the coaxiality of the propulsion ring 4 and the sealing layer 2, so as to ensure that the sealing layer 2 is pushed better, and the inner side of the other end of the propulsion ring 4 forms a gap relative to the outer side of the plug end 12 of the second pipe 1 to reduce friction.
[0053] Reference Figure 4 A plurality of balls 5 are rotatably connected to the inner side of one end of the propulsion arc plate 41 of the propulsion ring 4. The plurality of balls 5 are evenly distributed circumferentially on the propulsion ring 4. The plurality of balls 5 abut against the outer side of the plug-in end 12 of the second pipe 1 to reduce friction and facilitate rapid rotation of the propulsion ring 4.
[0054] Before use, the position of the fixing ear 42 can be changed to avoid collision between the fixing ear 42 and the connecting seat 323 during the rotation of the propulsion arc plate 41; the position of the connecting seat 323 can also be changed by sliding the connecting rod.
[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
