By changing the position of the positioning and fixing rings 701, while supporting the inner cylindrical template 2, it can adapt to the inner cylindrical template 2 with different cross-sectional diameters, and at the same time, it is convenient to quickly disassemble the inner cylindrical template 2.

[0037] like Figure 6 and Figure 7 As shown, the driving member 709 includes a rotating shaft 70901 rotatably arranged at the center position of the fixed plate 703, a fixed turntable 70902 is provided on the rotating shaft 70901, the fixed turntable 70902 is located in the control space, the outer edge of the fixed turntable 70902 is hinged to the mounting plate 706 through a bent connecting rod 70903, one end of the bent connecting rod 70903 is hinged to the fixed turntable 70902, and the other end of the bent connecting rod 70903 is hinged to the mounting plate 706.

[0038] like Figure 6 and Figure 7As shown, the fixed turntable 70902 is driven by the rotating shaft 70901, and the fixed turntable 70902 is rotated by rotating the rotating shaft 70901; when the turntable rotates, its position will change, and the movement is transmitted through the bent connecting rod 70903; since the fixed turntable 70902 is located in the control space and can move in the space, the drive system will be able to achieve synchronous changes in the entire control space; the rotation of the fixed turntable 70902 drives all connected bent connecting rods 70903 and the mounting plate 706 to achieve synchronous movement of multiple sliders 705; this can ensure the sliding consistency of the six sliders 705.

The first positioning holes 701001 are distributed at equal angles around the central axis of the fixing plate 703. When the rotating shaft 70901 is rotated to a suitable angle, the second positioning hole 701003 on the rotating handle 701002 is aligned with the first positioning hole 701001. By inserting the plug 701003 into the second positioning hole 701003 of the rotating handle 701002, the plug 701003 is inserted into the plug 701003. 1004, so that the rotation angle of the rotating shaft 70901 can be fixed; when the second positioning hole 701003 is aligned with the first positioning hole 701001, the rotating shaft 70901 can be locked at the specific angle by inserting the plug 701004; the insertion of the plug 701004 forms a mechanical connection between the rotating shaft 70901 and the fixed plate 703, which effectively prevents the rotating shaft 70901 from accidentally rotating during operation; the mechanical locking of the plug 701004 ensures the stability of the position of the rotating shaft 70901, and ensures that in actual work, the rotation angle will not change arbitrarily to meet the specified work requirements.

[0041] like Figure 5 As shown, this design enables the vibration surface to effectively contact the inner cylinder when the vibration plate 8 vibrates, thereby transmitting vibration energy; when the vibration motor is operating, vibration power is generated, and this force is transmitted to the outer surface of the vibration plate 8 and the corresponding arc-shaped vibration surface through the vibration motor; the excitation of the vibration motor causes the vibration plate 8 to vibrate with a certain frequency and amplitude, thereby expelling bubbles in the concrete.

[0042] like Figure 8 As shown, the outer cylindrical template 3 includes a sub-plug-in module 301 and a mother plug-in module 302, which are connected in an interlaced manner. The sub-plug-in module 301 and the mother plug-in module 302 are connected in an interlaced manner.

[0043] like Figure 8 As shown, a third slot 9 is provided on the outer ring surface of the outer cylindrical template 3, and the third slot 9 of the outer cylindrical template 3 is far away from the joint position between the sub-external plug-in module 301 and the mother external plug-in module 302, and the third plug-in strip 10 is located at a position far away from the joint between the sub-external plug-in module 301 and the mother external plug-in module 302, so that stress concentration at the nearby joint can be avoided and the stability of the overall structure is enhanced; a third plug-in strip 10 is provided in the third slot 9 of the outer cylindrical template 3, and several third plug-in strips 10 are locked and connected by a hoop 11, and several third plug-in strips 10 are locked and connected by the hoop 11, and this connection method forms a fastening and locking mechanism, so that the third plug-in strip 10 is firmly fixed in the third slot 9; this method effectively prevents the outer cylindrical template 3 from moving or loosening during use.

[0044] Working principle: When installing the construction template, the user first fixes the upper mold body 101 and the lower mold body 102 by means of screws 104, and obtains a stable bottom mold 1, places the bottom mold 1 flat on the ground, and inserts the assembled inner cylindrical mold 2 into the first socket 5 of the bottom mold 1, and inserts the assembled outer cylindrical mold 3 into the second socket 6 of the bottom mold 1. At this time, a hollow casting cavity 4 for forming the inspection well is formed between the outer cylindrical mold 3 and the inner cylindrical mold 2.

[0045] The inner support assembly 7 is then placed inside the inner cylindrical formwork 2, and the six sliders 705 are synchronously driven by the driving member 709, so that the sliders 705 slide along the sliding direction of the limiting slide groove 704, and drive the six built-in pressure blocks 707 to slide back and forth in the control space between the positioning and fixing rings 701. By changing the position of the positioning and fixing rings 701, while supporting the inner cylindrical formwork 2, it can adapt to inner cylindrical formworks 2 with different cross-sectional diameters, and at the same time, facilitate the quick disassembly of the inner cylindrical formwork 2.

[0046] Specifically, the fixed turntable 70902 is driven to rotate by rotating the rotating shaft 70901; when the turntable rotates, its position will change, and the movement is transmitted through the bent connecting rod 70903; since the fixed turntable 70902 is located in the control space and can move in the space, the drive system will be able to achieve synchronous changes in the entire control space; the rotation of the fixed turntable 70902 drives all connected bent connecting rods 70903 and the mounting plate 706 to achieve synchronous movement of multiple sliders 705; this can ensure the sliding consistency of the six sliders 705.

[0047] When the second positioning hole 701003 is aligned with the first positioning hole 701001, the rotating shaft 70901 can be locked at the specific angle by inserting the plug 701004; the insertion of the plug 701004 forms a mechanical connection between the rotating shaft 70901 and the fixed plate 703, which effectively prevents the rotating shaft 70901 from accidentally rotating during operation; the mechanical locking of the plug 701004 ensures the stability of the position of the rotating shaft 70901, ensuring that in actual work, the rotation angle will not change arbitrarily to meet specified work requirements.

[0048] When pouring concrete, the concrete will be poured into the pouring cavity 4 between the outer cylinder and the inner cylinder. With the pouring of concrete and the vibration of the vibration plate 8, a complete inspection well structure can be formed; the smooth surface of the outer cylinder template 3 and the inner cylinder template 2 can ensure the fluidity of the concrete, reduce the generation of bubbles, and finally form a smooth well wall.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
