[0002] In the construction of bridge abutments in underwater engineering, steel cofferdams are often used. When sealing the gap between the bottom plate of the steel cofferdam and the steel casing of the abutment, the concrete is poured using the underwater concrete tremie method. Specifically, the hopper and the hollow cylindrical tremie pipe are combined into a whole and lifted to the pouring position. Then, the mixed concrete is poured into the tremie pipe through the hopper and poured into the bottom of the steel cofferdam to achieve underwater sealing of the bottom. However, the cylindrical tremie pipe is fixed in position after connection, which is not convenient for fine adjustment according to the position of the steel cofferdam. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 An underwater concrete pouring device, comprising:

[0027] Several tubes 1 connected end to end, each tube 1 being flat-topped conical in shape;

[0028] Connection structure 2 is disposed on the surface of catheter 1 and is used to connect two catheters 1.

[0029] The connecting structure 2 includes a second connecting ring 210 fixedly connected to the top of the conduit 1. A first connecting ring 202 is provided on the top of the second connecting ring 210. A connector 203 is fixedly connected between the first connecting ring 202 and the second connecting ring 210. The connector 203 is a rubber material component. Two symmetrically distributed mounting blocks 201 are fixedly connected to the surface of the conduit 1. The surface of the mounting block 201 is provided with a mounting groove 208. The surface of the conduit 1 is provided with a threaded hole 209 communicating with the mounting groove 208. A positioning component 21 is provided on one side of the mounting block 201.

[0030] In use, several conduits 1 are connected end to end and fixed together by connecting structure 2. After the connection is completed, it is used to introduce concrete into the pre-installed steel formwork underwater for pouring.

[0031] The rubber material component connector 203 enables the first connecting ring 202 and the second connecting ring 210 to have a certain deformation capacity, so that after the two conduits 1 are connected, the lower conduit 1 can be moved to offset relative to the upper conduit 1, changing the angle between the installed multiple conduits 1, so that it can be adjusted according to the actual pouring construction position, avoiding the problem that the traditional conduit 1 is fixed in position after installation and is not conducive to adjustment.

[0032] Furthermore, the flat-topped conical conduit 1 is connected end to end, which facilitates the guidance of concrete. At the same time, the first connecting ring 202, the second connecting ring 210, and the connector 203 are set at the connection of the two conduits 1. Since the upper conduit 1 is inserted into the lower conduit 1, it will not affect the normal guidance of concrete.

[0033] Please see Figure 1-6 The top of the first connecting ring 202 is fixedly connected with two mounting rods 205 that match the mounting groove 208, and the surface of the mounting rods 205 is provided with through holes.

[0034] The surface of the second connecting ring 210 is fixedly connected with two symmetrically distributed connecting rods 204. The surface of the connecting rods 204 is provided with through holes 206 that are coaxially arranged with the through holes. The opposite sides of the two connecting rods 204 are provided with evenly distributed locking holes 207.

[0035] Both mounting rods 205 have a washer 211 embedded on their opposite sides, and the surface of the washer 211 has evenly distributed resistance-increasing grooves 212.

[0036] The mounting rod 205 is designed to allow the mounting rod 205 on the lower conduit 1 to be inserted into the mounting groove 208 of the upper conduit 1 during the connection of the two conduits 1. It serves as a guide during the installation process. After the mounting rod 205 is inserted into the mounting groove 208, the through hole on the mounting rod 205 corresponds to the threaded hole 209 opened in the mounting groove 208.

[0037] Please see Figure 1-6 The positioning component 21 includes a positioning rod 2101, the diameter of which is equal to the diameter of the through hole 206. One end of the positioning rod 2101 passes through the through hole 206 and is fixedly connected to a threaded rod 2106 that is threadedly connected to the threaded hole 209. The other end of the positioning rod 2101 is fixedly connected to a connecting block 2102.

[0038] A sealing ring 2107 is provided at one end of the positioning rod 2101 near the threaded rod 2106. The other end of the sealing ring 2107 is slidably connected to the inner wall of the positioning rod 2101. A second spring 2108 is fixedly connected between the surface of the sealing ring 2107 and the inner wall of the positioning rod 2101.

[0039] A pull block 2103 is provided on the surface of the connecting block 2102. A locking rod 2105 is fixedly connected to one side of the pull block 2103. The other end of the locking rod 2105 passes through the pull block 2103 and extends into the interior of the adjacent lock hole 207. A first spring 2104 is fixedly connected between the surface of the locking rod 2105 and the inner wall of the connecting block 2102.

[0040] After the two conduits 1 are connected, the positioning rod 2101 is passed through the through hole 206, the threaded rod 2106 is passed through the through hole and inserted into the threaded hole 209, and the positioning rod 2101 is rotated. During this process, the threaded rod 2106 is screwed into the threaded hole 209, and the positioning rod 2101 gradually approaches the mounting rod 205, causing the sealing ring 2107 to contact the washer ring 211. As the threaded rod 2106 is screwed in and the sealing ring 2107 is blocked by the washer ring 211, the second spring 2108 is gradually squeezed. After being compressed, the second spring 2108 drives the sealing ring 2107 to stick tightly to the washer ring 211 under its reaction force. The setting of the resistance groove 212 can increase the friction between the two and reduce the possibility of the threaded rod 2106 loosening.

[0041] After the positioning rod 2101 passes through the through hole 206, it can serve as a rotation center to adjust the position of the two conduits 1. During the adjustment process, pulling the pull block 2103 causes the locking rod 2105 to separate from the locking hole 207, while compressing the first spring 2104. After the adjustment is completed, releasing the pull block 2103 allows the locking rod 2105 to reset under the action of the first spring 2104 and insert into the interior of the adjacent locking hole 207, thus completing the limitation of the position of the two conduits 1.

[0042] Working principle: During the connection of the two conduits 1, the mounting rod 205 on the lower conduit 1 is inserted into the mounting groove 208 of the upper conduit 1. The positioning rod 2101 is passed through the through hole 206, and the threaded rod 2106 is passed through the through hole and inserted into the threaded hole 209. The positioning rod 2101 is rotated, and during this process, the threaded rod 2106 is screwed into the threaded hole 209. At the same time, the positioning rod 2101 gradually approaches the mounting rod 205, causing the sealing ring 2107 to contact the washer ring 211. As the threaded rod 2106 is screwed in and the sealing ring 2107 is blocked by the washer ring 211, the second spring 2108 is gradually compressed. After being pressed, the sealing ring 2107 is driven to tightly adhere to the gasket ring 211 under its reaction force. The setting of the resistance groove 212 can increase the friction between the two and reduce the possibility of the threaded rod 2106 loosening. After the positioning rod 2101 passes through the through hole 206, it can serve as the rotation center to adjust the position of the two guide tubes 1. During the adjustment process, pulling the pull block 2103 can drive the locking rod 2105 to separate from the locking hole 207, while compressing the first spring 2104. After the adjustment is completed, releasing the pull block 2103 can drive the locking rod 2105 to reset under the action of the first spring 2104 and insert it into the interior of the adjacent locking hole 207, thus completing the limitation of the position of the two guide tubes 1.
