The connecting block 7 is connected to the inner end face of the second side plate 4. A plurality of positioning holes 8 are formed in the connecting block 7. The plurality of positioning holes 8 are linearly arrayed on the connecting block 7. A connecting groove 9 is formed in the end face of the connecting block 7. An inserting plate 10 is arranged inside the adjusting structure 6, and the inserting plate 10 is connected to the inner end face of the first side plate 2.

[0028] As Figure 5 shown, a shrinkage groove 11 is formed in the inserting plate 10. A spring 12 is fixedly installed in the shrinkage groove 11. The upper end of the spring 12 is fixedly installed with a limiting rod 13. The connecting block 7 and the inserting plate 10 inside the adjusting structure 6 can be connected. The connecting groove 9 formed on the connecting block 7 inside the adjusting structure 6 is equal to the inserting plate 10. The diameter of the positioning hole 8 formed on the connecting block 7 inside the adjusting structure 6 is larger than the diameter of the limiting rod 13.

[0029] Working principle: When it is necessary to adjust the diameter of the supporting pile, by pressing down the limiting rod 13, the spring 12 installed at the bottom of the limiting rod 13 contracts downward, causing the limiting rod 13 to contract into the shrinkage groove 11. Then, by moving the first side plate 2 or the second side plate 4, the connecting block 7 or the inserting plate 10 is moved. Then, when the diameter of the supporting pile is adjusted, the inserting plate 10 drives the limiting plate to move to the positioning hole 8, causing the spring 12 to rebound and the limiting rod 13 to extend from the positioning hole 8 formed on the connecting block 7, so as to fix the connecting block 7 and the inserting plate 10, thereby adjusting the diameter of the guiding groove of the supporting pile. At the same time, the connecting block 7 and the inserting plate 10 inside the adjusting structure 6 can be disassembled, so that the first side plate 2 and the second side plate 4 can be separated well, facilitating disassembly for the staff to transport and carry.

[0030] As another embodiment, one end of the inserting plate 10 is provided with a pin hole corresponding to the positioning hole 8. The inserting plate 10 is inserted into the connecting groove 9 and fixed in the connecting block 7 by a pin.

[0031] Combined with the above embodiments, for an adjustable device for the diameter of the guiding groove of a bite-cast-in-place supporting pile in this embodiment, a first side plate 2 is arranged on the left end face of the main body 1 of the guiding groove plate of the supporting pile. A first arc-shaped guiding groove plate 3 is fixedly installed on the outer surface of the first side plate 2. A second side plate 4 is arranged at the right position of the guiding groove plate of the supporting pile. A second arc-shaped guiding groove plate 5 is fixedly installed on the outer surface of the second side plate 4. A clamping groove 14 is formed on one end face of both the first side plate 2 and the second side plate 4. A convex block 15 is fixedly installed on the other end face of both the first side plate 2 and the second side plate 4, as Figure 3 shown.

[0032] Working principle: By aligning the protruding blocks 15 installed on one end face of the first side plate 2 and the second side plate 4 with the card slots 14 opened on the other first side plate 2 and the second side plate 4, the splicing between two or even more supporting pile guide plate bodies 1 can be carried out, so as to extend them to the required length, and at the same time, the operation is relatively convenient.

[0033] 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 principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
