DETAILED DESCRIPTION

[0023] The technical scheme in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model.

[0024] Please refer to Figures 1-8 The utility model provides a technical scheme:

[0025] A underwater concrete pouring device, including carrier 1, install two openable positioning plate 2 in carrier 1, the opposite surface of two positioning plate 2 all are set up semicircular groove 21, and the guide pipe 5 of the upper end outer surface with the baffle ring is placed in the intercalation of two semicircular grooves 21, the baffle ring lower surface of guide pipe 5 and the upper surface of positioning plate 2 are pasted, and the diameter of semicircular groove 21 is same with the outer diameter of guide pipe 5, when two positioning plate 2 butt joint together, two semicircular grooves 21 butt joint together, can vertically position guide pipe 5, avoid and promote installation accuracy and collide with steel casing a.

[0026] The top end of the guide pipe 5 is detachably installed with the lower hopper 4, the upper surfaces of the positioning plates 2 are fixedly installed with the support frames 3 for lifting the lower hopper 4, the lower surface of the carrier frame 1 is installed with the flow guide device 6 capable of adjusting the discharge direction, the flow guide device 6 is located below the positioning plates 2, and the flow guide device 6 is used in cooperation with the steel casing a in the pile hole b, the drainage end of the flow guide device 6 is connected with the elastic drain pipe 7, during the concrete pouring process, the flow guide device 6 can collect the underground water overflowing from the steel casing a, and discharge the underground water uniformly by means of the elastic drain pipe 7, which can effectively prevent the underground water from spilling everywhere, thereby avoiding the construction site pollution, increasing the cleaning cost and the adverse effects on the normal operation of the construction equipment.

[0027] It should be noted that, as shown in Figure 2 and Figure 3 , the flow guide device 6 comprises two arc-shaped transfer brackets 61 fixedly welded and installed on the lower surface of the carrier frame 1, the two arc-shaped transfer brackets 61 are rotatably installed with the concentrating cylinder 62, the lower surface of the concentrating cylinder 62 is provided with a sleeve opening, the sleeve opening is fixedly installed with the rubber sealing ring 63, the inner diameter of the rubber sealing ring 63 is the same as the outer diameter of the steel casing a in the pile hole b, the outer surface of the concentrating cylinder 62 is fixedly installed with the drain pipe 621, the drain pipe 621 is located below the arc-shaped transfer bracket 61, and the drainage end of the drain pipe 621 is connected with the water inlet end of the elastic drain pipe 7.

[0028] Before installation between the flow guide device 6 and the steel casing a, the flow direction can be adjusted by rotating the concentrating cylinder 62 to drive the drain pipe 621 according to the environment and needs of the construction site, and in use, the concentrating cylinder 62 is sleeved on the top outer surface of the steel casing a through the rubber sealing ring 63, and the rubber sealing ring 63 can seal the connection between the two. When water overflows in the steel casing a, the concentrating cylinder 62 can block the water flow and guide the water into the elastic drain pipe 7 through the drain pipe 621 for unified discharge, effectively solving the problem of water drainage during underwater pouring.

[0029] In addition, as shown in Figure 4 , Figure 5 and Figure 6 , the bottom end outer surface of the lower hopper 4 is fixedly installed with the fixed ring A41, the lower surface of the fixed ring A41 is integrally formed with a plurality of L-shaped blocks 42 arranged at equal intervals in the circumferential direction, the top end outer surface of the guide pipe 5 is fixedly installed with the fixed ring B51, the upper surface of the fixed ring B51 is provided with a plurality of installation openings 511 arranged at equal intervals in the circumferential direction, the number of the installation openings 511 is the same as that of the L-shaped blocks 42, and the size of the installation openings 511 is the same as that of the L-shaped blocks 42.

[0030] When installing the hopper 4 and the guide tube 5, the hopper 4 is lifted with the help of an external lifting tool, the L-shaped block 42 is aligned with the position of the mounting port 511, and then the L-shaped block 42 is lowered into the mounting port 511 so that the upper surface of the fixing ring B51 is in contact with the lower surface of the fixing ring A41. Then, the entire hopper 4 is rotated to offset the L-shaped block 42 from the mounting port 511, thus completing the docking between the hopper 4 and the guide tube 5.

[0031] To ensure structural stability after the hopper 4 and guide tube 5 are connected, a positioning hole 52 is provided on the outer surface of the fixing ring B51, and a screw-on locking bolt 43 passes through the outer surface of any L-shaped block 42. When adjusting the position of the hopper 4, when the locking bolt 43 is aligned with the positioning hole 52, the end of the locking bolt 43 closest to the fixing ring B51 is inserted into the corresponding positioning hole 52 by screwing on the locking bolt 43. At this time, the L-shaped block 42 and the mounting port 511 are in a misaligned state, realizing the positioning and fixing of the hopper 4 and the guide tube 5.

[0032] Furthermore, to optimize the ease of rotational adjustment when the hopper 4 and the guide tube 5 are connected, an H-shaped support frame 3 is required, with two bullseye casters 31 bolted to its top. When the L-shaped block 42 is inserted into the mounting port 511 of the fixing ring B51, the rolling working surface of the bullseye casters 31 forms a line contact support with the outer surface of the hopper 4. By replacing sliding friction with rolling friction, the motion resistance torque between the hopper 4 and the support frame 3 can be reduced, thereby achieving labor-saving operation in the rotational adjustment process.

[0033] Finally, combining Figure 1 and Figure 2 As shown, the positioning plates 2 are rotatably installed inside the carrier 1 via hinges. When the two positioning plates 2 are joined, their front and rear surfaces are tightly fitted against the inner wall of the carrier 1, forming a lateral limit. At the same time, the two baffles 11 fixed inside the carrier 1 support the positioning plates 2, achieving vertical stability. This structural design, which combines horizontal limiting and vertical support, not only enhances the stability of the positioning plates 2 after joining, but also evenly distributes the load generated during the installation of the conduit 5, effectively ensuring the positional accuracy and overall stability of the conduit 5 during installation.

[0034] Working principle: in use, the carrier 1 is erected above the pile hole b with a steel casing a, then the two positioning plates 2 are turned inward to complete the butt joint, then the guide pipe 5 is inserted into the pile hole b from between the two semicircular grooves 21 by means of the external lifting tool, the guide pipe 5 is guided and positioned by the two semicircular grooves 21 during installation, and can fall smoothly into the pile hole b, when the retaining ring on the outer surface of the guide pipe 5 is attached to the positioning plate 2, the bottom end of the guide pipe 5 is kept a certain pouring distance from the bottom of the pile hole b, then the hopper 4 is connected with the guide pipe 5, and the stability of the hopper 4 is maintained by the support of the support frame 3, according to the pouring specification of the pile hole b, the concrete is poured into the pile hole b through the hopper 4 and the guide pipe 5 to complete the underwater concrete pouring work, the overflowed water during pouring is blocked by the concentrating cylinder 62 and is guided into the elastic drain pipe 7 through the drain pipe 621 for unified installation and discharge at the required position, which can effectively prevent the underground water from spilling everywhere, thereby avoiding the pollution of the construction site, the increase of cleaning cost and the adverse effects on the normal operation of the construction equipment.
