Description

Technical Field

[0001] This utility model relates to the field of building engineering, specifically a concrete guiding and pouring structure. Background Technology

[0002] Underwater concrete pouring construction typically employs the tremie method. Current tremie pouring involves directly inserting a tremie pipe underwater, relying on the concrete's own weight to pour the concrete. A waterproof plug inside the tremie pipe is forced out, and the concrete flows slowly from the bottom of the pipe, expanding outwards without being disturbed by surrounding water flow, thus ensuring quality. Underwater concrete pouring is suitable for underwater or underground engineering projects such as cofferdams, caisson foundations, well foundations, diaphragm walls, and pile foundations.

[0003] In the prior art, when irrigating underwater concrete, it is necessary to place an isolation ball between the hopper and the guide pipe to isolate the concrete from the guide pipe, thereby accumulating the concrete in the hopper. Then, the isolation ball is removed to allow the concrete to fall at once, compacting the sediment at the bottom. Each time it is used, the isolation ball needs to be fixed to the excess hoisting cable, which is quite cumbersome. Based on this, the present invention proposes a concrete guiding and irrigating structure. Utility Model Content

[0004] The purpose of this utility model is to provide a concrete guiding and filling structure in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a concrete guiding and filling structure, including a hopper, wherein a guide tube is rotatably connected to the inner side of the bottom end of the hopper via a thread, and a feeding mechanism is provided on the hopper;

[0006] The feeding mechanism includes an isolation unit and a limiting unit;

[0007] The isolation unit is used to isolate the concrete inside the hopper from the conduit.

[0008] The limiting unit is used to limit the movement of the isolation unit.

[0009] As a further improvement of this utility model: the isolation unit includes a movable plate and a shaft handle;

[0010] The movable plate is rotatably installed inside the hopper, and the movable plate is used to isolate the concrete in the hopper from the conduit.

[0011] The shaft handle is fixed to the end of the movable plate shaft, and the shaft handle is used to drive the movable plate to rotate synchronously.

[0012] As a further embodiment of this utility model: the limiting unit includes a rotating rod, a rotating ring, a limiting block, and a guide rod;

[0013] The rotating ring is rotatably installed inside the hopper, and the rotating ring is used to provide thrust to the guide rod;

[0014] The rotating rod is fixed to the outer wall of the rotating ring and extends to the outside of the hopper. The rotating rod is used to drive the rotating ring to rotate.

[0015] The limiting block is axially slidably installed inside the hopper and extends into the interior of the movable plate. The limiting block is used to limit the rotation of the movable plate.

[0016] The guide rod is fixed to the bottom of the limiting block and extends to the inner side of the rotating ring. The guide rod is used to drive the limiting block to move axially.

[0017] As a further improvement of this utility model: the top end of the rotating ring is formed with a guide groove for the guide rod to enter, and the guide groove is inclined.

[0018] As a further embodiment of this utility model: the outer wall of the movable plate is formed with a limiting groove for the insertion of the limiting block, and the interior of the hopper is formed with a rotation space for the movable plate to rotate.

[0019] As a further embodiment of this utility model: there are two movable plates and two shaft handles, with the two movable plates symmetrically distributed inside the hopper, and the two shaft handles respectively fixed to the ends of the shafts of the two movable plates.

[0020] As a further embodiment of this utility model: the outer wall of the hopper is formed with a rotating groove that matches the rotation trajectory of the rotating rod, and the outer wall of the guide rod matches the inner side of the top guide groove of the rotating ring.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] By setting up a feeding mechanism, when it is necessary to feed the concrete accumulated in the hopper, the rotating rod can be manually pulled to rotate along the outer wall of the hopper, thereby synchronously driving the limiting block to move axially. This causes the limiting block to move out from the inside of the movable plate, no longer providing a limit for the movable plate. Under the action of the concrete's gravity, the movable plate opens, allowing the concrete in the hopper to be guided into the guide pipe to compact the sediment. Compared with the traditional isolation ball isolation, this structure reduces the fixing and lifting operations of the isolation ball, reduces the use of cranes, further reduces costs, and improves work efficiency.

[0027] 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.

[0028] Please see Figures 1-3 In this embodiment of the present invention, a concrete guiding and filling structure includes a hopper 1, a guide tube 2 connected to the inner side of the bottom end of the hopper 1 by a threaded rotatable connection, and a feeding mechanism 3 disposed on the hopper 1.

[0029] The feeding mechanism 3 includes an isolation unit and a limiting unit;

[0030] The isolation unit is used to isolate the concrete inside the hopper 1 from the conduit 2;

[0031] Limiting units are used to limit the movement of isolation units;

[0032] The isolation unit includes a movable plate 301 and a shaft handle 302;

[0033] The movable plate 301 is rotatably installed inside the hopper 1. The movable plate 301 is used to isolate the concrete in the hopper 1 from the conduit 2.

[0034] The shaft handle 302 is fixed to the end of the shaft of the movable plate 301, and the shaft handle 302 is used to drive the movable plate 301 to rotate synchronously.

[0035] The limiting unit includes a rotating rod 303, a rotating ring 304, a limiting block 305, and a guide rod 306;

[0036] The rotating ring 304 is rotatably installed inside the hopper 1, and the rotating ring 304 is used to provide thrust to the guide rod 306;

[0037] The rotating rod 303 is fixed to the outer wall of the rotating ring 304 and extends to the outside of the hopper 1. The rotating rod 303 is used to drive the rotating ring 304 to rotate.

[0038] The limiting block 305 is axially slidably installed inside the hopper 1 and extends into the interior of the movable plate 301. The limiting block 305 is used to limit the rotation of the movable plate 301.

[0039] The guide rod 306 is fixed to the bottom of the limiting block 305 and extends to the inner side of the rotating ring 304. The guide rod 306 is used to drive the limiting block 305 to move axially.

[0040] In this embodiment: When using this device, concrete is directly poured into the interior of hopper 1, and the concrete is isolated from the guide pipe 2 by the movable plate 301. When the concrete accumulates to a certain extent, the rotating rod 303 can be manually pulled. The rotating rod 303 rotates along the outer wall of hopper 1 under force. The rotating rod 303 synchronously drives the rotating ring 304 to rotate, causing the guide groove on the rotating ring 304 to rotate circumferentially. The rotating guide groove will give the guide rod 306 a squeezing thrust, causing the guide rod 306 to move axially under the thrust of the guide groove. The guide rod 306, which moves under force, synchronously drives the limiting block 305 to move axially, causing the limiting block 305 to disengage from the interior of the movable plate 301, releasing the rotation limit on the movable plate 301. At this time, the concrete falls into the guide pipe 2 under its own weight and gravity, and the sediment at the bottom of the injection wellhead is compacted through the guide pipe 2. This reduces the fixing and pulling operations of the isolation ball and further improves the work efficiency.

[0041] Please refer to this carefully. Figures 1-3 The top of the rotating ring 304 is formed with a guide groove for the guide rod 306 to enter. The guide groove is inclined. The outer wall of the movable plate 301 is formed with a limiting groove for the limiting block 305 to be inserted. The inside of the hopper 1 is formed with a rotation space for the movable plate 301 to rotate. There are two movable plates 301 and two shaft handles 302. The two movable plates 301 are symmetrically distributed inside the hopper 1. The two shaft handles 302 are respectively fixed to the shaft ends of the two movable plates 301. The outer wall of the hopper 1 is formed with a rotation groove that matches the rotation trajectory of the rotating rod 303. The outer wall of the guide rod 306 matches the inner side of the top guide groove of the rotating ring 304.

[0042] In this embodiment: With this structure, after the concrete pouring at the wellhead is completed, the hopper 1 and the guide pipe 2 can be pulled out by a crane for cleaning. During the cleaning process, the shaft handle 302 can be manually rotated to make the shaft handle 302 drive the movable plate 301 to reset. At this time, the rotating rod 303 can be rotated again to make the limiting block 305 re-enter the interior of the movable plate 301 for easy use next time.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
