If the surrounding natural environment does not meet the curing conditions, especially when the construction is near coastal rivers, the area is open, the sea breeze is strong, and the area for pouring concrete is large. The block-by-block construction of concrete still cannot avoid the accelerated evaporation rate of moisture on the concrete surface caused by the sea breeze, then the concrete needs to be cured manually.

Natural curing usually involves covering the concrete with straw mats, frequently sprinkling water to keep it moist, preventing water evaporation from the concrete and ensuring normal cement hydration. The straw mats are then removed after curing is completed.

At the same time, the force of the wind acting on the guide plate 11 generates downward pressure on the guide plate 11, which provides stability to the maintenance device and reduces the probability of the wind blowing the maintenance device out of position.

[0039] like Figure 2 、 Figure 3 and Figure 5 As shown, a reinforcement structure is provided on the side of the mounting track 10 away from the support leg 2; the reinforcement structure includes a steel wire rope 12 fixed to the top of the mounting track 10; the end of the steel wire rope 12 away from the mounting track 10 is connected to an anchor rod 13; a U-shaped clamp 14 is fixed to the middle of the mounting track 10; the U-shaped clamp 14 matches the anchor rod 13; when working, after the maintenance device moves to the outside of the poured concrete, the anchor rod 13 is removed from the U-shaped clamp 14, the anchor rod 13 is inserted into the ground and fixed, the anchor rod 13 is fixedly connected to the top of the mounting track 10 using the steel wire rope 12, and the steel wire rope 12 is straightened and tightened, thereby improving the overall firmness and stability of the maintenance device.

At this time, the wire rope 12 on the winch cannot be released; after the anchor rod 13 is removed from the U-shaped clamp 14, the locking nut 24 on the second screw 22 is loosened, so that the spring 25 stretches and resets, pushing the drive rod 18 to slide to the outside of the connecting seat 17, driving the rotating face gear 19 to separate from the fixed face gear 16, so that the rotating shaft of the winch 15 is unlocked and can rotate; pulling the wire rope 12 drives the rotating shaft of the winch 15 to rotate, driving the connecting seat 17 and the drive rod 18 to rotate, so that The rotating face gear 19 rotates, driving the No. 2 screw 22 and the rotating ring 21 to rotate along the annular groove 20; after the anchor rod 13 is inserted into the ground and fixed, the driving rod 18 is rotated to drive the connecting seat 17 and the rotating shaft of the winch 15 to rotate, and the wire rope 12 is wrapped around the outer ring of the rotating shaft of the winch 15, and the wire rope 12 located on the outside of the winch 15 is tightened and straightened; after the wire rope 12 is tightened, the driving rod 18 is pushed to slide toward the inside of the connecting seat 17, so that the spring 25 is compressed, driving the rotating face gear 19 to engage with the fixed face gear 16, and rotating the locking nut 24 to lock the rotating face gear 19, thereby facilitating the construction workers to straighten and lock the wire rope 12, and at the same time facilitating the storage and use of the wire rope 12, thereby improving the convenience of operation for the construction workers.

At this time, the degree of bending of the steel wire rope 12 at this part is less, so that the square rope buckle 26 has less resistance to the movement of the steel wire rope 12; when strong winds generate When the thrust is large, the force on the wire rope 12 increases, and the force of the wire rope 12 on the two square rope buckles 26 increases, causing the square rope buckles 26 to rotate closer together, and the bending of the wire rope 12 at this position increases, thereby increasing the friction between the wire rope 12 and the square rope buckle 26, so that the force of the wire rope 12 acts on the outer shell of the reinforcement structure, reducing the force of the wire rope 12 on the rotating shaft of the winch 15, thereby improving the integrity of the winch 15 and ensuring the normal use of the reinforcement structure.

The threaded groove 27 is used to rotate the anchor rod 13 and insert it into the ground, and a thread is formed in the hole in the ground around the outer ring of the anchor rod 13, which increases the firmness of the anchor rod 13 inserted into the ground. At the same time, it is convenient for construction personnel to rotate and remove the anchor rod 13.

[0043] Example 2

[0047] After the anchor rod 13 is removed from the U-shaped clamp 14, the locking nut 24 on the second screw rod 22 is loosened, so that the spring 25 stretches and resets, pushing the driving rod 18 to slide to the outside of the connecting seat 17, driving the rotating face gear 19 to separate from the fixed face gear 16, and loosening the rotating shaft of the winch 15; pulling the wire rope 12, driving the rotating shaft of the winch 15 to rotate, driving the connecting seat 17 and the driving rod 18 to rotate, causing the rotating face gear 19 to rotate, driving the second screw rod 22 and the swivel 21 to rotate along the annular groove 20, and pulling the wire rope 12 out of the winch 15. At this time, the wire rope 12 passes through the two square rope buckles 26. When the construction workers slowly pull the wire rope 12, the square rope buckle 26 is subjected to less force, so that the square rope buckle 26 has less resistance to the movement of the wire rope 12; the anchor tip of the anchor rod 13 is tightened. After being inserted into the ground, a center axis wrench is used to clamp the outer ring of the sleeve handle 28, and the center axis wrench is turned to drive the anchor rod 13 to rotate. The threaded groove 27 is used to rotate the anchor rod 13 and insert it into the ground, and a thread is formed in the hole in the ground of the outer ring of the anchor rod 13, thereby increasing the firmness of the anchor rod 13 inserted into the ground; after the anchor rod 13 is inserted into the ground and fixed, the driving rod 18 is rotated to drive the connecting seat 17 and the rotating shaft of the winch 15 to rotate, and the wire rope 12 is wrapped around the outer ring of the rotating shaft of the winch 15, and the wire rope 12 located on the outside of the winch 15 is tightened and straightened; after the wire rope 12 is tightened, the driving rod 18 is pushed to slide toward the inside of the connecting seat 17, so that the spring 25 is compressed, driving the rotating face gear 19 to engage with the fixed face gear 16, and the locking nut 24 is turned to lock the rotating face gear 19;
