Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a borehole exploration device for bored piles. Background Technology

[0002] Drilled piles are increasingly used in engineering projects due to their advantages such as high bearing capacity, good stability, and small settlement. During the construction of drilled piles, the detection of hole diameter, hole shape, and verticality after drilling is an important procedure in the pile foundation construction process. In order to carry out these tests, we use a drilled pile borehole detection device.

[0003] Existing borehole exploration devices for cast-in-place piles are generally welded monolithic steel cage structures, which are not easy to carry and transport. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a borehole exploration device for bored piles, which solves the problem that the old borehole exploration device is an integral unit and is not easy to carry and transport.

[0005] To solve the above-mentioned technical problems, this utility model provides a borehole exploration device for bored piles. The exploration device is a cylindrical structure, including upper and lower rings and multiple connecting rods arranged between the rings. The connecting rods are in contact with the rings. A vertical rod is provided in the inner ring, and a lifting ring is provided above the vertical rod. A ring support device for supporting the ring and a fixing device for fixing the connecting rods are provided on the vertical rod.

[0006] In a preferred embodiment, the ring support device includes a first connector fitted onto the upright, a plurality of first support rods evenly distributed on the sidewall of the first connector, and a first support member installed in front of the first support rods; the front end of the first support member is provided with an arc shape matching the ring.

[0007] In a preferred embodiment, the fixing device includes a second connector disposed below the first connector and fitted under the upright, a plurality of second support rods evenly distributed on the side wall of the second connector, and a retaining seat disposed in front of the second support rods, wherein the connecting rod is engaged with the retaining seat; the retaining seat is provided with an arc shape matching the connecting rod.

[0008] In the preferred embodiment, the connecting rod has matching circular arcs at both the upper and lower ends.

[0009] In a preferred embodiment, the first connector has at least three mounting holes evenly distributed throughout, and the first connector is inserted into the mounting holes.

[0010] In a preferred embodiment, the second connector has at least four mounting holes evenly distributed throughout, and the second connector is inserted into the mounting holes.

[0011] In a preferred embodiment, a first blind hole is provided on the side where the first support rod is connected to the first support member, and a second blind hole is provided at the corresponding position of the first support member. A spring is fixed at the bottom of the first blind hole, and the other end of the spring is fixed to the bottom of the second blind hole.

[0012] The beneficial effects of this utility model are as follows: Because this utility model sets up a borehole exploration device for cast-in-place piles, by setting up a vertical rod, a circular ring support device and a fixing device for fixing the connecting rod inside the exploration device, the circular ring and the connecting rod can be separated without being welded together, thus reducing the overall volume and making it convenient to disassemble and transport after disassembly.

[0018] Please see Figure 1-3 As shown, this application provides a technical solution: a borehole exploration device for cast-in-place piles. The exploration device is a cylindrical structure, including two layers of rings 11 and multiple connecting rods 12 arranged between the rings 11. The connecting rods 12 are in contact with the rings 11. A vertical rod 13 is provided in the inner ring 11. A lifting ring 14 is provided above the vertical rod 13. A ring support device 2 for supporting the rings 11 and a fixing device 3 for fixing the connecting rods 12 are provided on the vertical rod 13.

[0019] In a preferred embodiment, the ring support device 2 includes a first connector 21 fitted onto the upright 13, a plurality of first support rods 22 evenly distributed on the side wall of the first connector 21, and a first support member 23 installed in front of the first support rods 22; the front end of the first support member 23 is provided with an arc shape matching the ring 11.

[0020] A circular hole can be provided on the side wall of the first connector 21 and the first support 23, and the first support rod 22 is inserted into the circular hole and fixed by interference fit.

[0021] The arc shape is designed to increase the contact area and improve overall stability, meaning that the overall structure remains stable even in the event of an external impact.

[0022] In a preferred embodiment, the fixing device 3 includes a second connecting member 31 disposed below the first connecting member 21 and fitted below the upright 13, a plurality of second support rods 32 evenly distributed on the side wall of the second connecting member 31, and a retaining seat 33 disposed in front of the second support rods 32, wherein the connecting rod 12 is engaged with the retaining seat 33; the retaining seat 33 is provided with an arc shape that matches the connecting rod 12.

[0023] A round hole can be provided on the side wall of the second connector 3 and the card holder 331, and the second support rod 32 can be inserted into the round hole and fixed by interference fit.

[0024] In a preferred embodiment, the connecting rod 12 has matching rings 11 at both the upper and lower ends.

[0025] In a preferred embodiment, the first connector 21 has at least three mounting holes evenly distributed, and the first connector 21 is inserted into the mounting holes.

[0026] In a preferred embodiment, the second connector 31 has at least four mounting holes evenly distributed, and the second connector 31 is inserted into the mounting holes.

[0027] In a preferred embodiment, a first blind hole 221 is provided on the side where the first support rod 22 is connected to the first support member 23, and a second blind hole 231 is provided at the corresponding position of the first support member 23. A spring 15 is fixed at the bottom of the first blind hole 221, and the other end of the spring 15 is fixed to the bottom of the second blind hole 231.

[0028] When the probe device is installed in place, the spring 15 is in a compressed state, which is equivalent to the spring 15 giving the first support member 23 a preload, which can stably support it around the ring 11 and improve the ring 11's ability to resist impact and not deform.

[0029] The connecting rod 12 is not welded to the ring 11; the connecting rod 12 serves as a support as a whole. The first connecting piece 21 and the second connecting piece 31 are provided with set screws on their sides. These set screws are used to lock the first connecting piece 21 and the second connecting piece 31 onto the upright 13, or other methods of fixing may also be used.

[0030] The steps for installing the borehole device are as follows: First, install the second connecting parts 31 of the upper and lower fixing devices 3, and tighten the set screws to lock the position of the second connecting parts 31. Then, install the second support rod 32 and the bracket 33, and then insert the connecting rod 12 into the bracket 33, with multiple connecting rods 12 aligned. Next, install the upper and lower ring support devices 2 in the same way, and then install the ring 11 on the first support part 23, aligning the entire assembly so that the upper and lower rings 11 and the ends of the connecting rods 12 make arc-shaped contact. This completes the entire installation. The disassembly steps of the borehole device are reversed, allowing the ring 11 and connecting rod 12 to be disassembled into a separate structure for easy transportation.
