Description

Technical Field

[0001] This invention relates to the field of cofferdam construction technology, specifically to a cofferdam structure for a foundation in deep soft soil and water. Background Technology

[0002] A foundation cap in deep soft soil and water refers to a foundation bearing system used to support buildings or other structures under soft soil foundation conditions. When the soil layer is deep and the soil is soft, special design and construction measures are required to ensure the stability and safety of the foundation. When constructing a foundation cap in deep soft soil and water, cofferdam measures are required. A cofferdam is a retaining structure set up around the construction area to isolate and control water bodies, create a dry working environment, and ensure the safety and smooth progress of construction.

[0003] During the construction of the foundation in deep soft soil environments, the cofferdam is constantly eroded by water flow. As the main load-bearing structure, the cofferdam is prone to tilting during erosion, which reduces its sealing effect and allows water and soil to flow into the construction site, affecting the normal progress of construction. Furthermore, the height of the cofferdam needs to be constantly adjusted for construction environments with different water depths, which compromises the safety of foundation construction and reduces construction efficiency. In addition, when no construction is underway, human activity or the approach of vessels to the cofferdam structure may cause damage and impact. This application aims to ensure the stability of the sheet piles under water flow impact and to provide perimeter protection when adjusting the height of the cofferdam, thereby ensuring the safe and stable construction of the foundation. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a cofferdam structure for foundations in deep soft soil water. This solves the problem that the cofferdam, as the main load-bearing structure, is constantly eroded by water flow, and is prone to tilting during erosion, leading to reduced sealing effect and easy inflow of water and soil into the construction site, affecting normal construction. Furthermore, the height of the cofferdam needs to be constantly adjusted for different water depths, resulting in compromised safety and low construction efficiency during foundation construction. In addition, human activity or the presence of vessels near the cofferdam structure may cause damage and impact.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cofferdam structure with a pier in deep soft soil, comprising a counterweight base and a support seat. A telescopic sleeve column is fixedly connected to the top of the support seat. A square seat is fixedly connected to the top of the telescopic sleeve column. A square cavity is formed in the center of the square seat. A servo motor is fixedly connected inside the square cavity. A driving bevel gear is fixedly connected to the drive end of the servo motor. A horizontal seat plate is fixedly connected to the top of the square seat. A cross-shaped cavity is formed inside the horizontal seat plate.

The device has screws, and the bottoms of the driven bevel gears on all four sides are meshed with the tops of the driving bevel gears. The outer walls of the screws on all four sides are threaded with movable plates, and the outer walls of the movable plates on all four sides are slidably connected to the inner walls of the cross-shaped cavity. C-shaped seats are fixedly connected to the middle of the four sides of the horizontal seat plate. The opposite ends of the screws on all four sides are rotatably connected to the middle of the C-shaped seats on all four sides. A seepage-proof slope is fixedly connected to the top of the horizontal seat plate. A cofferdam body is rotatably connected to the top of the seepage-proof slope on all four sides. An adjusting plate is rotatably connected to the middle of the outer side of the cofferdam body on all four sides. The bottoms of the adjusting plates on all four sides are rotatably connected to the tops of the movable plates on all four sides.

[0006] Preferably, L-shaped plates are rotatably connected to the inner walls of the front and rear cofferdam bodies, and slots are fixedly connected to the inner walls of the left and right cofferdam bodies, with the slots on both sides fitting into the L-shaped plates on both sides.

[0007] Preferably, a column is fixedly connected to the top of the counterweight base, a telescopic waterproof shell is fixedly connected inside the column, and a hydraulic cylinder is fixedly connected inside the telescopic waterproof shell.

[0008] Preferably, the piston rod end of the hydraulic cylinder is fixedly connected to a sliding plate, the top of the telescopic waterproof shell is fixedly connected to the bottom of the sliding plate, and the four sides of the column are provided with sliding grooves in the middle. The four outer walls of the sliding plate are slidably connected to the inner walls of the four sliding grooves.

[0009] Preferably, the outer wall of the skateboard is fixedly connected to a hollow frame, the inner wall of the hollow frame is slidably connected to the outer wall of the column, and an adjusting rod is rotatably connected to the center of each of the four sides of the hollow frame. The end of the adjusting rod away from the hollow frame is rotatably connected to the center of the outer side of the four C-shaped seats.

[0010] Preferably, a U-shaped plate is snapped onto the top of the cofferdam body on all four sides, and an infrared emitter is fixedly connected to the top four corners of the U-shaped plate. A U-shaped tube is fixedly connected to the outer wall of the U-shaped plate, and several nozzles are evenly fixedly connected to the outer circumference of the U-shaped tube.

[0011] Preferably, a water supply pipe is fixedly connected inside the U-shaped tube, a water pump is provided below the U-shaped tube, the inlet end of the water supply pipe is fixedly connected to the outlet end of the water pump, and a flexible hose is fixedly connected to the inlet end of the water pump.

[0012] Preferably, a control switch is fixedly connected to the top of the receiving seat, and the control switch is electrically connected to the servo motor, the infrared transmitter and the hydraulic cylinder.

[0013] Working Principle: In deep, soft soil and water construction environments, the cofferdam structure is stably set up in the environment by a counterweight base. Then, a servo motor drives the active bevel gear to rotate, which in turn rotates the driven bevel gears meshing on the four sides inside the horizontal base plate. This, in turn, rotates the four side screws. With the cooperation of the cross-shaped cavity, the four movable plates slide against the inner wall of the cross-shaped cavity. When the four movable blocks engage with the inner wall of the cross-shaped cavity, the four adjusting plates cooperate to form a triangular stable support structure on the outer side of the cofferdam body. The matching and fitting of the four L-shaped plates with the four side slots prevents the cofferdam body from tilting due to the continuous impact of water flow during use. The cofferdam body is made of high-strength, corrosion-resistant materials to ensure its service life, thereby improving the sealing effect of the cofferdam, preventing water and soil from flowing into the construction site, and ensuring the normal progress of construction. The control switch... The hydraulic cylinder operates, causing the sliding plate to slide inside the chute, which in turn drives the hollow frame to slide up and down on the outer wall of the column. This allows the entire structure above the square base to move up and down via the adjusting rod and telescopic sleeve. The height of the cofferdam body can be adjusted according to the water depth to ensure the safety and efficiency of the foundation construction, achieving a flexible and safe construction effect. Infrared emitters are installed above the cofferdam body. The infrared rays emitted by the four infrared emitters form a closed-loop infrared coil. When no construction is underway, if a person or vessel gets too close to the cofferdam body and interrupts the infrared rays, the control switch will activate the water pump to inject water into the loop pipe through the hose and water delivery pipe, and then spray it out through the four side nozzles. This prevents personnel or vessels from getting too close and causing damage or impact to the cofferdam body, ensuring the normal use of the cofferdam body and thus ensuring the normal progress of the foundation construction.

[0014] This invention provides a cofferdam structure with a foundation in deep soft soil. It has the following beneficial effects:

[0015] 1. This invention controls a servo motor to drive the active bevel gear to rotate via a control switch, thereby causing the driven bevel gears meshing on the four sides inside the cross seat plate to rotate. This, in turn, causes the four side screws to rotate. With the cooperation of the cross-shaped cavity, the four side movable plates slide on the inner wall of the cross-shaped cavity. When the four side movable blocks are engaged with the inner wall of the cross-shaped cavity, the four side adjusting plates cooperate to form a triangular stable support structure on the outer side of the four side cofferdam body. Furthermore, the four side L-shaped plates match and fit with the four side slots, thereby preventing the cofferdam body from tilting due to the continuous impact of water flow during use. This improves the sealing effect of the cofferdam, prevents water and soil from flowing into the construction site, ensures the normal progress of construction, and achieves the technical effect of stable use and preventing tilting and water ingress.

[0016] 2. This invention controls the operation of the hydraulic cylinder by a control switch, causing the slide plate to slide inside the chute, thereby driving the hollow frame to slide up and down on the outer wall of the column. This allows the structure above the square base to move up and down as a whole through the adjusting rod and telescopic sleeve column. The height of the cofferdam body can be adjusted according to the different water flow depths, ensuring the safety and efficiency of the foundation construction and achieving the technical effect of flexible adjustment and safe construction.

[0017] 3. This invention installs infrared transmitters above the cofferdam body. The infrared rays emitted by the four infrared transmitters form a closed-loop infrared coil. When no construction is underway, if a person or vessel gets too close to the cofferdam body and interrupts the infrared rays, the control switch will control the water pump to inject water into the loop pipe through the hose and water delivery pipe, and then spray it out through the four side nozzles. This prevents personnel or vessels from getting too close, avoids damage or impact to the cofferdam body, and ensures the normal use of the cofferdam body. Attached Figure Description
