Specific implementation manner

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figure 1-6 , the present invention provides a technical solution: a device for preventing mud overflow during the construction of bored cast-in-place piles, including an anti-overflow cover 1, a side plate 2, a fixed connecting rod 3, a fixed connecting cap 4, a support plate 5, an auxiliary support 6, a positioning pin 7, a mounting block 8, a first convex block 9, a mounting groove 10, a connecting mechanism 11, a fixed column 12, a spring 13, a movable plate 14, a pull ring 15 and a second convex block 16.

[0032] When using the device for preventing mud overflow during the construction of bored cast-in-place piles, as Figure 1 and Figure 2 shown, first move the components of the device to the corresponding positions for the pouring of the cast-in-place pile, fit the anti-overflow covers 1 at the left and right ends with each other, and side plates 2 are fixedly connected to the front and rear ends of the anti-overflow cover 1. Insert the fixed connecting rod 3 into the middle of the side plate 2, and then rotate the fixed connecting caps 4 threadedly connected to the left and right ends of the fixed connecting rod 3 so that the fixed connecting caps 4 are closely attached to the side plate 2. Through the settings of the side plate 2, the fixed connecting rod 3 and the fixed connecting cap 4, it is convenient to limit the anti-overflow covers 1 on the left and right sides to each other, thereby facilitating the rapid assembly of the device;

[0033] After the assembly is completed, as Figure 3 , Figure 4 , Figure 5 and Figure 5As shown, a support plate 5 is fixedly connected to the side of the anti-overflow cover 1, and an installation block 8 is fixedly connected to the upper end of the auxiliary support 6. At the same time, a first convex block 9 is fixedly connected to the side of the installation block 8 close to the anti-overflow cover 1. In combination with the setting of the connection mechanism 11, the connection mechanism 11 includes a fixed column 12 fixedly connected to the side of the support plate 5, a spring 13 sleeved on the outer surface of the fixed column 12, a movable plate 14 fixedly connected to the movable end of the spring 13, a pull ring 15 fixedly connected to the middle of the movable plate 14, and a second convex block 16 for positioning. By pulling the pull ring 15, the movable plate 14 slides between the fixed column 12. At this time, the movable plate 14 squeezes the spring 13, causing the spring 13 to undergo elastic deformation;

[0034] Then, the installation block 8 is driven by the auxiliary support 6 to be connected to the middle of the support plate 5 in a snap-fit manner, and the installation block 8 drives the first convex block 9 to be inserted into the installation groove 10 to position between the support plate 5 and the installation block 8. Then, the pull ring 15 is directly released. At this time, the spring 13 restores its elastic deformation and pushes the movable plate 14 to slide between the fixed column 12. At this time, the movable plate 14 is engaged with the second convex block 16, which is convenient for limiting between the installation block 8 and the support plate 5 and facilitating the installation of the auxiliary support 6 on the outside of the anti-overflow cover 1. Moreover, the lower end of the installation block 8 is directly placed on the ground. Then, the positioning pins 7 are respectively inserted into the front and rear sides of the lower end of the auxiliary support 6, and the lower ends of the positioning pins 7 are inserted into the ground. Through the settings of the auxiliary support 6 and the positioning pins 7, it is convenient to assist in supporting the anti-overflow cover 1, thereby improving the stability of the equipment during use and preventing it from tipping over. Through the setting of the anti-overflow cover 1, it can effectively prevent the mud from splashing outwards during the pouring process. At the same time, the anti-overflow cover 1 is in a trumpet shape with a large opening, which is convenient for the pouring of the mud. Moreover, the equipment can be disassembled and recycled by performing the reverse operation of the above operations.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
