[0041] Optionally, there are a plurality of slide grooves 505, which are circumferentially distributed on the rotating member 504; there are a plurality of sliding rods 503, which are circumferentially distributed on the peripheral side of the mounting frame 501; and a first support plate 502 and a slider 506 are provided at both ends of each sliding rod 503.

[0042] In this embodiment, the chute 505 is in an arc shape; the mounting frame 501 is in a "M" shape; and the rotating member 504 is in a disc shape. After the hole 1 is excavated, and the operator sets a template around the hole 1 and pours a circle of concrete to form a protective wall, the operator can place the supporting structure in the hole 1, and then the operator rotates the rotating member 504 to make the slider 506 slide along the track of the chute 505, and the sliding rod 503 slide on the mounting frame 501, so that the first support plate 502 is close to the first protective wall template 2, so that the first support plate 502 abuts against the first protective wall template 2, so that the first support plate 502 supports the first protective wall template 2, provides good support for the first protective wall template 2, enhances the strength of the protective wall of the first protective wall template 2, reduces the occurrence of the protective wall being crushed by the soil around the hole wall, and improves the safety during construction.

[0043] In this embodiment, by providing a plurality of first support plates 502, the supporting effect of the support structure on the first wall protection template 2 is enhanced. At the same time, holes 1 with different diameters have different diameters of the first wall protection template 2. The operator can control the rotation angle of the rotating member 504 according to actual needs, so that the plurality of first support plates 502 support the first wall protection templates 2 with different diameters. The support structure is easy for the operator to adjust, and can adapt to a variety of holes 1 with different diameters. It is easy to adjust and has good applicability.

In this embodiment, the first supporting device 5 for supporting the second wall protection template 3 has a supporting platform 11 and a drill bit 12. When the supporting structure is placed in the hole 1, the supporting platform 11 contacts the bottom of the hole 1, reducing the friction of the bottom of the hole 1 on the first supporting device 5 located below.

The operator can operate the driving member 6 to rotate the rotating member 504 located above, so that the first supporting device 5 located above supports the first wall protection template 2. The driving rod 7 transmits the driving force of the driving member 6 on the first supporting device 5 located above to the first supporting device 5 located below, so that the first supporting device 5 located below supports the second wall protection template 3, so that the first wall protection template 2 and the second wall protection template 3 can be supported at the same time, so that the support structure is more stable when supporting the first wall protection template 2 and the second wall protection template 3, and the support effect is better. At the same time, the operator can select a driving rod 7 with an adapted length according to the depth of the hole 1 to adapt to holes 1 of different depths, thereby improving the scope of application of the support structure. It should be noted that the support structure needs to select first support plates 502 of different thicknesses according to the different depths of the first wall protection template 2 and the second wall protection template 3.

[0046] Optionally, it also includes: there are two swing rods 8, and the swing rods 8 are swinging relative to the driving rod 7; the second support plate 9 is hingedly set on the swing rod 8, and after the swing rod 8 swings, the second support plate 9 is close to or away from the third wall protection template 4.

[0048] Optionally, there are multiple second support plates 9 , and the multiple second support plates 9 are arranged around the circumference of the driving rod 7 .

[0049] In this embodiment, when the driving member 6 drives the rotating member 504 located above, the driving rod 7 rotates with the rotating member 504, so that the two moving blocks 10 are close to each other, and the several swing rods 8 on the two moving blocks 10 are swung, and the two upper and lower adjacent swing rods 8 are close to each other, and the second support plate 9 is propped up in a direction deviating from the axis of the driving rod 7, so that the second support plate 9 and the third wall protection template 4 are abutted, supporting the third wall protection template 4 and strengthening the strength of the third wall protection template 4.

[0050] In this embodiment, the operator can set several sections of threaded sections 701 with opposite rotation directions on the driving rod 7 according to the depth of the hole 1, and then set several groups of moving blocks 10 to support the third wall protection template 4 in the middle of the hole 1 of different depths, thereby improving the use range of this support structure. It is easy to operate and easy to adjust. It should be noted that this support structure requires the selection of second support plates 9 with different arc lengths according to the different depths of the third wall protection template. It should be noted that this support structure requires the selection of second support plates 9 with different arc lengths according to the different depths of the third wall protection template 4.
