Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a reusable pile hole protection device. Background Technique
[0002] The foundation pile hole is the hole of the cast-in-place concrete pile drilled to reinforce the underground foundation and improve the bearing capacity and seismic resistance of the building foundation. After the foundation pile hole is drilled, a steel reinforcement cage is inserted into the hole, and then concrete is poured. After the concrete solidifies, it becomes the foundation pile in close contact with the surrounding soil layer. This method of making piles is cheaper than driving concrete piles or steel piles and saves construction time. It is a widely used method in modern building construction. In order to enable the foundation pile to bear tensile force, measures are taken to expand the bottom of the pile hole after it is drilled to the bottom. The foundation pile formed by pouring in this way is thick at the bottom and thin at the top, and its tensile resistance (such as seismic resistance) is much greater than that of a straight pile relying solely on friction to bear tensile force, and the construction is not troublesome. In order to prevent people from accidentally falling into the pile hole, a protection device is generally installed on the pile hole.
[0003] For example, a reusable pile hole closing protection device with the publication number CN214423365U does not have any locking mechanism. During long-term use, the two protection caps open when encountering collision or vibration, resulting in a reduced protection effect. To solve the above problems, a reusable pile hole protection device is proposed. Utility Model Content

[0014] A reusable pile hole protection device proposed by the present utility model. First, place the locking disc on the bottom plate, then insert the long rod into the insertion hole, and pull the long rod to drive the rotation of the locking disc. When observing that the positioning block is aligned with the locking mark on the protective cover, it indicates that the locking block has been embedded into the locking groove, thus locking the protective cover on the mounting base, avoiding accidental detachment of the protective cover, and ensuring the safety of the staff. Regardless of the usage period, the staff can judge whether the protective cover is safely locked by observing the position of the positioning block. The reinforcing ribs inside the protective cover help to improve the overall stability of the protective cover, thereby enhancing the safety of the protective cover. If it is necessary to open the protective cover, only need to rotate the locking disc to release the lock on the protective cover, and then the protective cover can be easily opened through the inspection hole. In addition, the limiting plate on the locking disc and the limiting groove are used in cooperation, which can effectively limit the rotation range of the locking disc. This enables the operator to rotate the locking disc more conveniently. At the same time, this also avoids the situation that when the locking disc rotates too large an angle, the locking block may come out of the locking groove, thus preventing the locking failure of the locking block to the protective cover, greatly improving the safety. Place the locking disc on the bottom plate, one end of the reinforcing support block is connected to the bottom plate, and the other end is connected to the mounting base, which can enhance the connection strength between the bottom plate and the mounting base and prevent the locking disc from falling off. The limiting block is snapped into the locking groove, and the limiting block can prevent the locking disc from tilting or falling off when opening the protective cover, improving the protection effect of the pile hole.

One end of the reinforcing support block 8 is fixedly connected to the bottom plate 7, and the other end is fixedly connected to the mounting base 1, enhancing the connection strength between the bottom plate 7 and the mounting base 1 and preventing the locking disc 2 from falling off. Insert the long rod into the jack 15 and rotate the locking disc 2 to insert the limiting block 9 into the locking groove 14. The limiting block 9 can prevent the locking disc 2 from tilting or falling off when opening the protective cover 3.
[0033] Working principle: In actual use, first, place the locking disc 2 on the bottom plate 7, then insert the long rod into the jack 15, and pull the long rod to drive the rotation of the locking disc 2. When it is observed that the positioning block 16 is aligned with the locking mark on the protective cover 3, it indicates that the locking block 5 has been embedded into the locking groove 14, thus locking the protective cover 3 on the mounting base 1, avoiding accidental detachment of the protective cover 3, and thereby ensuring the safety of the staff. Regardless of the length of the usage cycle, the staff can judge whether the protective cover 3 is safely locked by observing the position of the positioning block 16. The reinforcing ribs 6 inside the protective cover 3 help to improve the overall stability of the protective cover 3, and further improve the safety of the protective cover. If it is necessary to open the protective cover 3, only need to rotate the locking disc 2 to release the lock on the protective cover 3, and then the protective cover 3 can be easily opened through the inspection hole 4. In addition, the limiting plate 12 on the locking disc 2 and the limiting groove 13 are used in cooperation, which can effectively limit the rotation range of the locking disc 2. This enables the operator to rotate the locking disc 2 more conveniently. At the same time, this also avoids that when the rotation angle of the locking disc 2 is too large, the locking block 5 may come out of the locking groove 14, thus avoiding the locking failure of the locking block 5 on the protective cover 3 and greatly improving the safety. Place the locking disc 2 on the bottom plate 7. One end of the reinforcing support block 8 is connected to the bottom plate 7, and the other end is connected to the mounting base 1. This can enhance the connection strength between the bottom plate 7 and the mounting base 1 and prevent the locking disc 2 from falling off. The limiting block 9 is snapped into the locking groove 14. The limiting block 9 can prevent the locking disc 2 from tilting or falling off when the protective cover 3 is opened, improving the protection effect of the pile hole.
