Description

Technical Field

[0001] This utility model relates to the field of underwater concrete construction technology, and in particular to an underwater concrete spraying and pouring device. Background Technology

[0002] Underwater concrete pouring technology is a key technology for the repair and restoration of underwater structures such as dams, bridge foundations, docks, and other marine or river structures. Traditional underwater pouring methods face several challenges, including the potential for cement paste loss, reduced strength and durability due to direct contact between concrete and water, and uneven concrete quality. For damage to the bottom plane of hydraulic structures, techniques such as tremie pipe method, suspended tank method, and bag method can be used for repair. These methods can directly deliver concrete to the bottom, reducing the risk of leakage and water segregation in the poured concrete.

[0003] Concrete pouring on irregular underwater facades presents more complex challenges. This typically involves construction on vertical or inclined surfaces underwater. Due to the unevenness of the facade foundation, it is difficult to seal and install the formwork. This can lead to concrete leakage and water erosion during the pouring process, which can easily affect the quality of the concrete. Utility Model Content

[0025] The following is in conjunction with the appendix Figures 1-3 The present invention will be described in further detail below.

[0026] Please refer to the attached diagram in the instruction manual. Figures 1-3This utility model provides an embodiment of an underwater concrete spraying and pouring device, comprising a trolley system 1, a high-pressure air isolation system 2, a spraying system 3, and a coating system 4. The trolley system 1 includes a trolley frame 11, a camera and lighting device 12, a trolley central controller 13, a trolley driver 14, a suction machine 15, and wheels 16. The camera and lighting device 12 is fixedly installed on the front side of the top surface of the trolley frame 11 and consists of an underwater camera and an underwater light. The trolley system 1 is equipped with camera and lighting equipment, which allows operators to monitor the construction status in real time, improving the safety and accuracy of construction.

[0027] The trolley central controller 13 is fixedly installed on the rear side of the top surface of the trolley frame 11, and the trolley central controller 13 is electrically connected to the water platform control system through a signal cable.

[0028] The trolley drive 14 is fixedly installed on the rear side of the trolley frame 11. The trolley drive 14 controls the movement of the trolley system 1 in the forward, up and down, and left and right directions underwater by adjusting the direction of the trolley drive 14.

[0029] The suction machine 15 is fixedly installed at the bottom of the trolley frame 11. The suction machine 15 is turned on by the trolley central controller 13, so that the trolley system 1 can be attached to the slope by suction. The mobility and suction function of the trolley system 1 enable the equipment to work stably in complex underwater environments, thereby enhancing the feasibility of construction.

[0030] Wheels 16 are located at the bottom of the trolley frame 11. Steering devices 17 are provided on the wheels 16. There are several wheels 16, which are distributed in a rectangular shape at the bottom of the trolley frame 11. The wheels 16 are rotated by the steering devices 17. An inner arc-shaped groove 18 is provided inside the trolley frame 11. By operating the trolley driver 14 and the steering devices 17, the direction of the wheels 16 is adjusted, thereby moving the inner arc-shaped groove 18 of the trolley system 1 to the position to be poured.

[0031] The trolley system 1 is electrically connected to the trolley central controller 13 via a power cord. The trolley central controller 13 is electrically connected to the steering gear 17, the suction machine 15, the trolley driver 14, the cover film roller 41, and the camera and lighting equipment 12 via power cords and signal cables, respectively.

[0032] All internal equipment connections of the trolley system 1 are sealed by high-pressure resistant and waterproof sealing strips. The high-pressure resistant and waterproof sealing strips are existing technology and are 30 MPa in size.

[0033] The high-pressure air isolation system 2 includes an air compressor 21 and a high-pressure air duct 22. The high-pressure air duct 22 is fixedly installed inside the trolley frame 11. The air compressor 21 is installed on top of the high-pressure air duct 22. Several air jets 23 are distributed in an arc shape in the inner arc-shaped groove 18. The air compressor 21 is connected to the air jets 23 through the high-pressure air duct 22. When the air compressor 21 is turned on, high-pressure air is delivered to the air jets 23 through the high-pressure air duct 22, blowing the water in the inner arc-shaped groove 18 until there is no water. Thus, the high-pressure air isolation system 2 can effectively block the direct contact between the surrounding water and the shotcrete, thereby reducing the loss of cement slurry.

[0034] The spraying system 3 includes a mortar spraying machine 31 and a mortar pipe 32. The mortar pipe 32 is fixedly inserted into the trolley frame 11. The lower end of the mortar pipe 32 extends into the inner arc-shaped groove 18 and is fixedly equipped with a mortar spraying head 33. The mortar spraying machine 31 is fixedly installed at the upper end of the mortar pipe 32. By starting the mortar spraying machine 31, the mortar is sprayed into the pouring area in the inner arc-shaped groove 18 through the mortar pipe 32 and the mortar spraying head 33. The spraying situation is observed through the camera and lighting equipment 12. The spraying system 3 enables the concrete to be sprayed evenly under high pressure, ensuring the uniformity and integrity of the concrete pouring.

[0035] The lamination system 4 includes a cover film roller 41, a cover film body 43, an elastic pressure rod 44, and a flattening pendulum 45. The cover film roller 41 is fixedly installed on the inner top wall of the inner arc-shaped groove 18. The cover film body 43 is wound onto the cover film roller 41. When the cover film body 43 is rolled out, it is coated with underwater adhesive. The lower ends of the elastic pressure rod 44 and the flattening pendulum 45 are both provided with balls 42. The cover film body 43 is pressed and sealed with underwater adhesive by the balls 42 of the elastic pressure rod 44. The concrete inside the membrane body 43 is flattened by the rolling ball 42 of the flattening pendulum 45. After the defect points are sprayed onto the surface, the trolley continues to move forward and starts the covering membrane roller 41. After the covering membrane body 43 is coated with underwater adhesive, it is squeezed and sealed by the elastic pressure rod 44. Then the concrete surface is flattened by the flattening pendulum 45. Through the automatic covering and flattening of the membrane by the membrane covering system 4, the surface of the newly poured concrete is ensured to be flat and isolated from water, preventing the influence of external water on the quality of the concrete.

[0041] Step 3: Trolley system 1 is in place;

[0042] The trolley central controller 13 turns on the suction machine 15, and uses suction to adhere the trolley system 1 to the slope surface;

[0043] Step 4: Activate the high-pressure air isolation system 2;

[0044] When the air compressor 21 is turned on, high-pressure air is delivered to the air jet 23 through the high-pressure air pipe 22, blowing the water in the inner arc groove 18 out with the air flow;

[0045] Step 5: Start the injection mixing system 3;

[0046] Start the mortar spraying machine 31. The mortar is sprayed into the pouring area in the inner arc-shaped groove 18 through the mortar pipe 32 and the mortar spraying head 33. The spraying situation is observed through the camera and lighting equipment 12.

[0047] Step Six: Start the film coating system 4;

[0048] After the defect points are sprayed onto the surface, the trolley continues to move forward, the covering film roller 41 is activated, the covering film body 43 is coated with underwater adhesive, and then the edges are sealed by the elastic pressure bar 44, and then the concrete surface is flattened by the flattening pendulum 45.
