Description

Technical Field

[0001] This utility model relates to the field of protection inside manually excavated pile holes, and more specifically, to a protection device for the inside of manually excavated pile holes. Background Technology

[0002] Manually excavated bored piles (often simply called manual piles) are a common method of pile foundation construction, suitable for environments with complex soil layers, especially in places with weak foundations or high groundwater levels. The basic process involves manually excavating a pile hole, then filling it with pile foundation materials (such as steel reinforcement and concrete) to form the pile foundation structure and provide ground support. To improve the stability of the filling material, a circular protective cylinder is usually placed inside the pile hole to enhance the stability during concrete forming.

[0003] Based on the above, the inventors have discovered that most existing protective cylinders for pile holes are made of wooden boards spliced ​​together with steel nails. Since the wooden boards need to be fixed together with steel nails, it takes a lot of time and is very cumbersome before use. At the same time, they need to be disassembled during dismantling and transportation, which reduces the convenience of using the device. Therefore, in view of this, the inventors have studied and improved the existing structure to provide a protective device for manually excavated pile holes, in order to achieve a more practical purpose. Utility Model Content

[0004] 1. Technical problems to be solved

It can be easily assembled manually, and it is also easy to disassemble and dismantle manually, which improves the convenience of the device during transportation and use.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A protective device for manually excavated pile holes includes three arc-shaped composite plates. Each of the three arc-shaped composite plates has three arc-shaped reinforcing plates on its inner side. Three recessed grooves are evenly distributed on the inner walls of the three arc-shaped composite plates. Three limiting rods are fixedly installed inside the recessed grooves. Three locking hooks, in the shape of an "L", are fixedly installed on the outer walls of the arc-shaped reinforcing plates. A pair of fixing plates are fixedly installed on the outer walls of one end of each of the three arc-shaped composite plates. Each pair of fixing plates has an opening on its outer wall. A pair of through grooves are formed on the outer walls of the other end of each arc-shaped composite plate. The openings and through grooves are symmetrically positioned, and fasteners are inserted into the interior of each fixing plate.

[0009] Furthermore, the two sides of the three arc-shaped composite plates are all attached to each other, and the three arc-shaped composite plates are cylindrical in shape, with the edge of the outer wall of the arc-shaped reinforcing plate attached to the inner wall of the arc-shaped composite plate.

[0010] Furthermore, one end of each of the three locking hooks is inserted into the interior of the three recessed slots and engages with the limiting rod.

[0011] Furthermore, a limiting groove is provided at the top of one end of each set of arc-shaped reinforcing plates, and a limiting block is fixedly installed at the other end of each set of arc-shaped reinforcing plates.

[0012] Furthermore, the limiting blocks at one end of each of the three sets of arc-shaped reinforcing plates are mutually engaged and installed into the limiting grooves at one end of the adjacent arc-shaped reinforcing plates, and the three sets of arc-shaped reinforcing plates are circular.

[0013] Furthermore, each of the three arc-shaped composite plates has a pair of fixing grooves at its top end, and each of the three arc-shaped composite plates has a pair of fixing blocks fixedly installed at its top end, with the positions of the fixing grooves and the fixing blocks being symmetrical to each other.

[0014] 3. Beneficial effects

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] This solution, through the installation of limiting rods, engaging hooks, fixing plates, and fixing blocks, involves inserting the engaging hooks on the outer walls of the three arc-shaped reinforcing plates one by one into the recessed grooves when the device is put into use, ensuring the arc-shaped reinforcing plates are flush with the inner walls of the arc-shaped composite plates. Then, the arc-shaped reinforcing plates are moved downwards, causing the engaging hooks to engage with the limiting rods inside the recessed grooves, thus fixing the arc-shaped reinforcing plates to the interior of the arc-shaped composite plates. Subsequently, the three arc-shaped composite plates are assembled. Simultaneously, the limiting block at one end of one arc-shaped reinforcing plate is inserted into the limiting groove at one end of another arc-shaped reinforcing plate, thus securing the three sets of arc-shaped reinforcing plates. The panels are assembled by aligning the openings on the fixing plates of one curved panel with the slots on another curved panel, ensuring the fixing plates fit snugly against the outer walls of the other panel. Fasteners are then inserted into the openings and slots and tightened. This completes the assembly of the curved panels. When multiple curved panels are needed, the fixing blocks at the bottom of one panel are inserted into the fixing grooves at the top of another panel. This effectively prevents displacement after multiple panels are assembled. This device significantly improves the speed of manual assembly and the convenience of disassembly and transport.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Example:

[0025] Please see Figures 1-4 A protective device for manually excavated pile holes includes three arc-shaped composite plates 1. Each of the three arc-shaped composite plates 1 has three arc-shaped reinforcing plates 2 on its inner side. Three recessed grooves 3 are evenly distributed on the inner walls of the three arc-shaped composite plates 1. Three limiting rods 4 are fixedly installed inside the recessed grooves 3. Three locking hooks 5, shaped like the letter "L," are fixedly installed on the outer edges of the outer walls of the arc-shaped reinforcing plates 2. A pair of fixing pieces 8 are fixedly installed on the outer walls of one end of each of the three arc-shaped composite plates 1. Each pair of fixing pieces 8 has an opening 9 on its outer wall. A pair of through grooves 10 are opened on the outer walls of the other end of each arc-shaped composite plate 1. The positions of the openings 9 and through grooves 10 are symmetrical. Fasteners 11 are inserted into the interior of the fixing pieces 8. This device, by combining the three arc-shaped composite plates 1 and simultaneously disassembling and assembling the internal arc-shaped reinforcing plates 2, greatly improves the convenience of manual installation and transportation in practical use.

[0026] See Figure 3 , Figure 4The two sides of the three arc-shaped composite plates 1 are all attached to each other, and the three arc-shaped composite plates 1 are cylindrical in shape. The edge of the outer wall of the arc-shaped reinforcing plate 2 is attached to the inner wall of the arc-shaped composite plate 1. One end of each of the three locking hooks 5 is inserted into the interior of the three inner grooves 3 and is locked to the limiting rod 4. By inserting the locking hooks 5 on the outer wall of the arc-shaped reinforcing plate 2 into the interior of the inner groove 3 and locking the locking hooks 5 into the limiting rod 4 inside the inner groove 3, the arc-shaped reinforcing plate 2 can be fixed to the interior of the arc-shaped composite plate 1.

[0027] See Figure 1 , Figure 2 , Figure 3 Each set of arc-shaped reinforcing plates 2 has a limiting groove 6 at one end, and a limiting block 7 is fixedly installed at the other end of each set of arc-shaped reinforcing plates 2; the limiting blocks 7 at one end of the three sets of arc-shaped reinforcing plates 2 are interlocked and installed into the limiting groove 6 at one end of the adjacent arc-shaped reinforcing plates 2, and the three sets of arc-shaped reinforcing plates 2 are circular. When the three arc-shaped combined plates 1 are installed, the limiting blocks 7 on the three sets of arc-shaped reinforcing plates 2 will be inserted into the limiting groove 6, so that the arc-shaped reinforcing plates 2 can be firmly spliced ​​inside the arc-shaped combined plates 1.

[0028] See Figure 1 , Figure 3 Each of the three arc-shaped combination plates 1 has a pair of fixing grooves 12 at its top, and each of the three arc-shaped combination plates 1 has a pair of fixing blocks 13 fixedly installed at its top. The positions of the fixing grooves 12 and the fixing blocks 13 are symmetrical to each other. After the three arc-shaped combination plates 1 are assembled, multiple units can be combined vertically, so that the fixing blocks 13 at the bottom of the upper unit are inserted into the fixing grooves 12 at the top of the lower unit. This can effectively prevent the device from shifting when used in combination.

[0029] In use: First, manually insert the locking hooks 5 on the outer walls of the three arc-shaped reinforcing plates 2 one by one into the inner groove 3, ensuring that the arc-shaped reinforcing plates 2 are flush with the inner wall of the arc-shaped composite plate 1. Then, move the arc-shaped reinforcing plates 2 downwards, causing the locking hooks 5 to engage with the limiting rods 4 inside the inner groove 3, thereby fixing the arc-shaped reinforcing plates 2 into the interior of the arc-shaped composite plate 1. Then, assemble the three arc-shaped composite plates 1. Simultaneously, the limiting block 7 at one end of the arc-shaped reinforcing plate 2 will insert into the limiting groove 6 at one end of another arc-shaped reinforcing plate 2, thus... The three sets of arc-shaped reinforcing plates 2 are combined and spliced ​​together. Then, the through-hole 9 on the fixing piece 8 on the outer wall of the arc-shaped combined plate 1 is aligned with the through groove 10 on another arc-shaped combined plate 1. At the same time, the fixing piece 8 is attached to the outer wall of the other arc-shaped combined plate 1. Then, the fastener 11 is inserted into the through-hole 9 and through groove 10 and the nut of the fastener 11 is tightened. The arc-shaped combined plate 1 is then assembled. When multiple sets of arc-shaped combined plates 1 are needed, the fixing block 13 at the bottom of the arc-shaped combined plate 1 is inserted into the fixing groove 12 at the top of another set of arc-shaped combined plates 1. The whole assembly can then be placed into the pile hole for protection.
