It mainly includes sea reclamation projects, seaport projects, estuary management projects, marine dredging projects, coastal protection projects, coastal tidal power generation projects, marine farms, environmental protection projects, and fishery projects. For the implementation of coastal engineering, caissons are usually used. Caissons are a type of deep foundation and are mostly used for wharves and breakwaters.

[0003] A search revealed that the Chinese patent "A Transparent Caisson for Port and Coastal Engineering" (authorization announcement number CN219886901U) includes an upper caisson with multiple columns arranged sequentially from left to right at its bottom, each column having a column base at both ends; a lower caisson connected between the column bases and located below the columns; and a retaining plate disposed on one side of the column surface, with a rib plate connected to one side of the retaining plate. The fully sealed upper and lower caissons, along with several rows of large-diameter hollow columns, are connected to form a floating caisson, making it more suitable for areas with shallow rock strata. This design meets environmental protection requirements while avoiding the large workload and high construction difficulty associated with cast-in-place piles.

[0004] However, the above method has the following drawbacks in actual use: the use of multi-point sand filling method can easily lead to uneven sand filling during the sand filling process, which can cause the caisson to tilt and become unstable, affecting the quality and safety of the project. Utility Model Content

[0005] Therefore, it is necessary to provide a permeable caisson for port and coastal engineering to address the problem of uneven sand filling, which can cause the caisson to tilt and become unstable.

[0006] A permeable caisson for port and coastal engineering includes a grid box and a set of columns installed on its outer side. The outer side of the grid box is provided with a filling mechanism. It also includes a flow guiding mechanism, which is arranged between the set of columns and is used to uniformly guide sand into the corresponding columns to reduce the overall tilting and instability. The flow guiding mechanism includes a turntable and a set of arc-shaped pipes. The turntable has a set of inclined material guiding channels inside, and one end of the arc-shaped pipes extends into the interior of the columns.

[0007] In one embodiment, a circular box is provided on the outer side of the turntable, and the other end of the arc-shaped tube is connected to the circular box. A feed pipe that is connected to the filling mechanism is installed on the circular box.

[0008] In one embodiment, a set of balls is provided on the outer side of the turntable, and the outer side of the balls extends into the interior of the arc-shaped tube.

[0009] In one embodiment, a support block is movably sleeved on the outer side of the ball, and a scraper block fixedly installed on the outer side of the support block is slidably sleeved on the outer side of the turntable, the scraper block contacting the inner bottom wall of the round box.

[0010] In one embodiment, the inner top wall of the scraper is provided with a set of springs, one end of which is connected to the support block.

[0011] In one embodiment, the injection mechanism includes a motor, the output shaft of which is mounted with a square shaft via a coupling, one end of which is inserted into the interior of a turntable, and a drive plate is provided on the outer side of the square shaft.

[0012] In one embodiment, the interior of the grid box is provided with a set of cavities communicating with the columns, and the exterior of the grid box is provided with a toe plate.

[0013] In one embodiment, the top of the compartment is provided with an outer wall, and both the column and the round box are located inside the outer wall. Beneficial effects

[0014] 1. By setting up a turntable and arc-shaped pipes, the turntable receives the sand material, and then, during the rotation, the sand material is discharged along the corresponding guide chute. Then, the arc-shaped pipes at each point guide the sand material into the corresponding column, thus completing the uniform distribution of the material, ensuring uniform sand filling, reducing the phenomenon of tilting and instability of the caisson, and ensuring the quality and safety of the project.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] The following is combined Figures 1-5 This invention describes a permeable caisson for port and coastal engineering.

[0026] In one embodiment, a permeable caisson for port and coastal engineering includes a grid 100 and a set of columns 200 installed on its outer side. A filling mechanism 300 is provided on the outer side of the grid 100. It also includes a flow guiding mechanism 400, which is disposed between the set of columns 200 and is used to uniformly guide sand into the corresponding columns 200 to reduce the overall tilting and instability. The flow guiding mechanism 400 includes a turntable 410 and a set of arc-shaped pipes 420. A set of inclined material guide channels 411 is opened inside the turntable 410, and one end of the arc-shaped pipes 420 extends into the interior of the column 200.

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a round box 412 is provided on the outer side of the turntable 410, and the other end of the arc-shaped tube 420 is connected to the round box 412. A feed pipe that is connected to the filling mechanism 300 is installed on the round box 412, and one end of the feed pipe extends into the interior of the turntable 410.

[0028] In this embodiment, after the grid box 100 is transported to the designated position, the sand is introduced into the round box 412 along the filling mechanism 300. Then the material is introduced into the turntable 410, and the turntable 410 is driven to rotate. The centrifugal force is used to throw the material out along the corresponding guide groove 411 for uniform distribution. Then the material enters the corresponding column 200 along the corresponding arc-shaped pipe 420, completing the sand filling operation.

[0029] It should be noted that the column 200, the grid box 100 and the round box 412 in this application are all prefabricated and cast together with reinforced concrete.

[0030] The specifications of the sand used in this application can be selected according to the size of the caisson and the construction requirements;

[0031] During the sand filling operation, sand filling is carried out at regular intervals. After sand filling, compaction treatment can be selected according to the construction environment and needs. Regular observation can be carried out after sand filling to ensure that the balance is within the error range before proceeding with other operations or sand filling treatment.

[0032] The feed pipe is set on the round box 412 for point sand filling operation. Users can also add feed pipes connected to the corresponding column 200 according to the construction environment and needs to carry out single-area sand filling and weight increase treatment, and carry out subsequent balance auxiliary adjustment and construction needs in special environments.

[0033] like Figure 4 As shown, a set of balls 413 are provided on the outer side of the turntable 410, and the outer side of the balls 413 extends into the interior of the arc-shaped tube 420.

[0034] The use of ball bearings 413 allows for repeated compaction and pushing of the sand material within the arc-shaped tube 420 at various points, reducing the occurrence of blockages.

[0035] like Figure 3 and Figure 4 As shown, a support block 414 is movably sleeved on the outer side of the ball 413, and a scraper 415 is slidably sleeved on the outer side of the support block 414 and fixedly installed on the outer side of the turntable 410. The scraper 415 contacts the inner bottom wall of the round box 412.

[0036] The scraper block 415 moves to drive the material outside the turntable 410 and assist the material in entering the arc tube 420. At the same time, the support block 414 follows the scraper block 415 and drives the ball bearing 413 to move accordingly.

[0037] like Figure 4 As shown, a set of springs 416 are provided on the inner top wall of the scraper block 415, and one end of the spring 416 is connected to the support block 414.

[0038] During the movement of the scraper block 415 driven by the turntable 410, when the ball 413 is misaligned with the arc tube 420, the spring 416 is in a compressed state. When the ball 413 moves to the next arc tube 420, the spring 416 pushes against and drives the ball 413 to reset.

[0039] like Figure 4 As shown, the injection mechanism 300 includes a motor, and the output shaft of the motor is mounted with a square shaft 310 via a coupling. One end of the square shaft 310 is inserted into the interior of the turntable 410, and a drive plate is provided on the outer side of the square shaft 310.

[0040] During the sand filling operation, the drive motor causes the square shaft 310 to drive the material drive plate to move, rotating the sand material into the turntable 410. At the same time, the square shaft 310 drives the turntable 410 to follow the movement.

[0041] It should be noted that the round box 412 is equipped with a sleeve for supporting the motor, and two sand guide tubes are installed on the sleeve, with the bottom end of the sand guide tubes located below the motor.

[0042] The grouting mechanism 300 is an external sand-filling mechanism. After the sand-filling operation is completed, the grouting mechanism 300 can be transported and moved away.

[0043] The drive plate is inclined and its thickness gradually decreases outward along the axis of the square shaft 310. At the same time, a guide hopper is provided inside the sleeve on the outside of the square shaft 310 to facilitate the auxiliary guidance of the sand.

[0044] like Figure 1 , Figure 2 and Figure 3 As shown, the compartment 100 has a cavity inside that communicates with the column 200, and the compartment 100 has a toe plate on the outside; the top of the compartment 100 has an outer wall, and the column 200 and the round box 412 are both inside the outer wall.

[0045] The external wall design can withstand external horizontal forces, and the toe plate design makes the caisson more stable during its descent.

[0046] It should be noted that the exterior wall can be fitted with corresponding holes and channels depending on the construction environment and requirements.

[0047] Working principle: The components of the caisson are manufactured and processed in the factory and cast into a whole using reinforced concrete. The integrated caisson is towed to the designated position by a barge. Sand is introduced into the turntable 410 inside the round box 412. During the sand introduction process, the square shaft 310 drives the turntable 410 to move and disperse the material. During the material guiding process, the ball bearings 413 repeatedly squeeze the ports of the arc-shaped tubes 420 at various points to reduce the sand blockage phenomenon in the arc-shaped tubes 420. After the sand filling operation is carried out for a preset time, the caisson sinks to the designated area, completing the overall operation.

[0048] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
