Description

Technical Field

[0001] This utility model relates to the field of open-face caisson technology, and in particular to an open-face caisson for use in port and coastal engineering. Background Technology

[0002] Caissons are a type of deep foundation, commonly used in wharves and breakwaters. They are topped, bottomless box-shaped structures with internal partitions, allowing them to float in water. Their sinking or floating is controlled by adjusting the ballast water inside the caisson. During construction, the caisson is filled with sand or rubble, and then a top cover is added to seal it, forming a topped, bottomed box-shaped structure that serves as the main load-bearing and wall structure. An airlock is installed on the top cover to facilitate the entry and exit of personnel, materials, and soil, while maintaining a constant air pressure within the chamber.

[0003] For example, Chinese utility model patent application number 202320946582.7 discloses a permeable caisson for port and coastal engineering, comprising: an upper compartment, on which multiple columns are arranged sequentially from left to right at the bottom, with column bases connected to both ends of the columns; a lower compartment, connected between the column bases and located below the columns; and a retaining plate, disposed on one side of the column surface, with ribs connected to one side of the retaining plate. This utility model provides a permeable caisson for port and coastal engineering, using a fully sealed upper and lower compartment connected to several rows of large-diameter hollow columns to form a floating caisson, which is more suitable for areas with shallow rock strata. It meets environmental protection requirements and avoids the problems of large workload and high construction difficulty associated with cast-in-place piles.

[0004] However, the aforementioned permeable caissons, during sand filling, rely on continuous vibration from a vibrating motor, resulting in low filling efficiency and difficult subsequent maintenance. Therefore, those skilled in the art have developed a permeable caisson for port and coastal engineering to address the problems mentioned in the background section. Utility Model Content

[0025] This utility model has the following beneficial effects:

[0026] 1. Compared with existing technologies, the permeable caisson used in port and coastal engineering has a sand feeding mechanism that allows cast iron rods to intermittently impact the outer wall of the sand box.

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.

[0035] Reference Figure 1-4 The present invention provides a permeable caisson for port and coastal engineering, comprising an upper compartment box 1, a connecting column 2 fixed to the bottom of the upper compartment box 1, a column base 3 installed at the bottom of the connecting column 2, a lower compartment box 4 at the bottom of the column base 3, a sand inlet box 5 installed at the top of the upper compartment box 1, a sand feeding pipe 6 installed at the top of the sand inlet box 5, a sand feeding mechanism 7 installed at the top of the upper compartment box 1, a stabilizing mechanism 8 installed at the top of the upper compartment box 1, and an installation pad 9 installed on the outside of the sand inlet box 5.

[0036] The sand feeding mechanism 7 includes a housing 71, a mounting base 72 fixed to the bottom of the housing 71, a servo motor 73 fixed to one inner wall of the housing 71, a reinforcing bracket 74 fixed to the bottom of the servo motor 73, a cast iron gear 75 fixed to the outside of the output shaft of the servo motor 73, a cast iron rack 76 meshing with the bottom of the cast iron gear 75, a support sleeve 77 fixed to the bottom of the cast iron rack 76, a support guide rod 78 fixed between the inner walls of the two sides of the housing 71, and a cast iron rod fixed to one side of the support sleeve 77. 79. When the support sleeve 77 moves, it can drive the cast iron rod 79 to move simultaneously. The support sleeve 77 has a through hole inside, the size of which is adapted to the size of the support guide rod 78, so that the support sleeve 77 can be movably sleeved on the outside of the support guide rod 78. The outer shell 71 has a through hole inside, the size of which is adapted to the size of the cast iron rod 79, so that the cast iron rod 79 can move normally in the horizontal direction. The mounting base 72 and the upper grid box 1 are fixedly connected, and the support sleeve 77 and the cast iron rack 76 are welded and fixed.

[0037] The stabilizing mechanism 8 includes a reinforcing plate 81, a reinforcing connecting pad 82 fixed on one side of the reinforcing plate 81, an anti-dislodgement slider 83 fixed at the bottom of the reinforcing connecting pad 82, a guide sleeve 84 installed on the top of the upper compartment box 1, an L-shaped limiting sleeve 85 fixed on the top of the mounting pad 9, a cast iron threaded post 86 fixed on the top of the mounting pad 9, a cast iron nut 87 threadedly connected to the outer side of the cast iron threaded post 86, and a groove provided inside the reinforcing plate 81, the size of which is adapted to the size of the cast iron threaded post 86.

[0038] Working principle: The sand feeding mechanism 7, installed via the sand feeding pipe 6, activates the servo motor 73 inside the outer casing 71 during sand filling. The output shaft of the servo motor 73 drives the cast iron gear 75 to rotate intermittently clockwise and counterclockwise, causing the cast iron rack 76 to reciprocate horizontally. During this process, the support sleeve 77 at the bottom of the cast iron rack 76 can move outside the support guide rod 78, providing support and guidance. After the cast iron rack 76 moves, the cast iron rod 79 intermittently impacts the outer wall of the sand box 5, effectively breaking down the cohesion and static friction between sand particles during filling, creating a continuous flow and assisting in the sand filling process. To avoid blockages during sand filling and for ease of maintenance, this device is equipped with a stabilizing mechanism 8. After the sand inlet box 5 is fixed on top of the upper grid box 1, the mounting pad 9 on the outside of the sand inlet box 5 is fixedly connected to the upper grid box 1. Then, the anti-detachment slider 83 can be moved to move the reinforcing connecting pad 82, allowing the reinforcing plate 81 on the outside of the reinforcing connecting pad 82 to fit onto the outside of the cast iron threaded column 86. Then, the cast iron nut 87 is threadedly connected to the cast iron threaded column 86, which easily completes the fixation of the position of the reinforcing plate 81. The top of the mounting pad 9 is reinforced and limited by the reinforcing plate 81, ensuring a stable connection between the sand inlet box 5 and the upper grid box 1.

[0039] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
