Description

Technical Field

[0001] This utility model belongs to the field of underwater formwork concrete construction technology, specifically relating to an auxiliary floating platform for underwater formwork concrete construction. Background Technology

[0002] Underwater formwork concrete construction involves pouring concrete into formwork bags underwater. The concrete formwork bags are finished bag-shaped fabrics made of high-strength long filaments. Under pressure, the dry bags are filled with fluid concrete or cement mortar, which hardens to form concrete slabs. This construction technology does not require diversion during application, provides good slope integrity, and resists wind and waves. Therefore, it has been widely used in many construction projects.

[0003] The positioning and laying of geotextile bags are crucial for ensuring a tight cover of the slope after installation. The geotextile bags have excellent fiber flexibility, and are laid with three sides in water and one side facing the shore. During installation, the top edge is secured with steel stakes or ropes, while divers assist in fully unfolding the bag at the bottom edge and sides from the water's surface. The bag is then lowered by divers using sandbags. Traditional laying methods are strenuous for divers, inefficient, and pose certain safety hazards, thus requiring improvement. Utility Model Content

[0004] To address the aforementioned issues, this utility model discloses an underwater formwork concrete construction auxiliary floating platform that is easy to assemble and disassemble, can assist divers in their work, has reusable pontoons, low construction costs, and is safe and reliable.

[0006] An underwater formwork concrete construction auxiliary floating platform is a platform composed of several unit pontoons, guardrails, and wooden planks. The platform is U-shaped. A metal frame is fixed to the surface of each unit pontoon. A walkway frame is longitudinally arranged above the three metal frames. The walkway frame is a rectangular frame welded from steel pipes. The wooden planks are placed inside the walkway frame. Adjacent walkway frames are connected by steel pipe fasteners. The guardrails are vertically arranged on the outside of the walkway frame.

[0007] As an improvement of this utility model, the metal frame is composed of angle steel and flat iron.

[0008] As an improvement of this utility model, the walkway frame is fixed together with the metal frame by Ω-shaped round steel.

[0009] As an improvement of this utility model, the surface of the wooden board is provided with steel bars, and the two ends of the steel bars are welded to the steel pipe.

[0010] As an improvement of this utility model, the guardrail is installed on the outside of the walkway frame by means of steel pipe fasteners.

[0011] The beneficial effects of this utility model are as follows:

[0012] (1) Workers can be arranged on the platform to assist the divers in their work, fully stretching out the plastic bag, reducing the workload of the divers and improving their safety;

[0024] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0025] As shown in the figure, the underwater formwork concrete construction auxiliary floating platform of this utility model is set in the water and is a man-portable platform in the shape of a U-shape, with three sides enclosed and one side missing (its end is secured by cables). Its structure mainly consists of multiple unit floats 1, guardrails 2, and wooden planks 3. The unit floats 1 are submerged in the water, and a metal frame 4 is fixed to the surface of each unit float 1. Three unit floats 1 plus a walkway frame 7 form a group. A walkway frame 7 is longitudinally welded above the three metal frames 4, and the walkway frame 7 is fixed to the metal frames 4 by Ω-shaped round steel bars 11. Figure 4 As shown, the walkway frame 7 is a rectangular frame welded from steel pipes 8. The wooden planks 3 are placed inside the walkway frame 7. Adjacent walkway frames 7 are connected by steel pipe fasteners 9. The guardrails 2 are vertically placed on the outside of the walkway frame 7 and are also connected by steel pipe fasteners.

[0026] The platform opening faces the slope. During operation, the geotextile bag is lowered from the opening, and workers pull it away from the shore on both sides until the bottom and sides of the geotextile bag are basically in place. Then, the diver secures it. Workers on the platform assist the diver by fully unfolding the geotextile bag, reducing the diver's workload and improving their safety.

[0027] The unit pontoon 1 described in this utility model serves as the main component of the platform, capable of floating on the water surface. A metal frame 4 is fixed to the surface of the unit pontoon 1. The metal frame 4 is composed of angle steel 6 and flat iron 10. Figure 2 As shown, the wooden plank 3 serves to prevent collisions and allows for the welding of other components. It is installed within the walkway frame 7, and the surface of the wooden plank 3 is provided with reinforcing bars 12. The two ends of the reinforcing bars 12 are welded to steel pipes 8. Figure 5 and 6 As shown, to ensure that the wooden plank 3 will not shake or slip during work, a steel pipe guardrail 2 is installed on the outside to improve worker safety. The guardrail 2 is connected to the walkway frame 7 by steel pipe fasteners. Figure 7 As shown, the whole assembly and disassembly are convenient, the unit floating box 1 can be reused, and the construction cost is low.

[0028] Normally, the molded bag is a rectangular structure. This utility model adopts a modular design, which can be assembled according to the size of the molded bag, and the corners are right angles, which conform to the shape of the molded bag, making it convenient and practical.

[0029] It should be noted that the above content merely illustrates the technical concept of this utility model and cannot be used to limit the scope of protection of this utility model. For those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and all such improvements and modifications fall within the scope of protection of the claims of this utility model.
