[0029] Combine the following Figures 1 to 8 The utility model is described in detail.

[0030] Example:

[0031] A support structure, in some embodiments, such as Figures 1 to 8As shown, it includes a support column 1, and a conical head 2 is provided at the bottom of the support column 1; a slide groove 3 is provided on one side of the support column 1 with an axis arranged in the vertical direction, and the slide groove 3 is connected with multiple retaining plates 4 by sliding and overlapping through a sliding mechanism; a clamping mechanism for clamping the retaining plate 4 is provided on the top of the support column 1; a detachable connecting mechanism for assembling and connecting with other retaining plates 4 is provided at the left and right ends of the retaining plate 4; an auxiliary supporting mechanism is provided on the other side of the support column 1.

[0032] When in use, the staff first nails the support column 1 into the corresponding position of the foundation pit, and makes the slide 3 face the direction of the slope, then overlaps and installs the retaining plate 4 on the support column 1 through the sliding mechanism, and presses and installs the retaining plate 4 through the pressing mechanism, and then uses the same method to install another support column 1 to other corresponding positions of the foundation pit, and then connects two adjacent retaining plates 4 through the detachable connecting mechanism; the other side of the support column 1 is improved by the auxiliary supporting mechanism. By using this device, it is more convenient than the existing method of laying the pads one by one after nailing the short piles, and it has higher stability and integrity.

[0033] It is worth mentioning that the distance between adjacent support columns 1 needs to meet the design standards to ensure the installation and coordination of adjacent retaining plates 4 .

[0035] During specific use, when installing the retaining plate 4, the first slider 5 of the retaining plate 4 is slidably matched with the slide groove 3, and the limit block 7 is matched with the limit groove 6, and the above process is repeated. When the retaining plates 4 overlap to a corresponding number to reach the designed height, a clamping mechanism is installed above the topmost retaining plate 4 to complete the installation of the retaining plate 4.

[0036] In some embodiments, the clamping mechanism includes a clamping block 8 arranged above the first retaining plate 4, and a second sliding block 9 matching the slide groove 3 is provided on one side of the clamping block 8; a fastening cover 10 is fixedly connected to the top of the clamping block 8; the interior of the support column 1 is also provided with a threaded groove 11 opening upward, and a bolt 12 matching the threaded groove 11 is sleeved in the fastening cover 10.

[0044] In some embodiments, the angle between the inclined rod 16 and the supporting rod is set to be between 45°.

[0045] When used specifically, the auxiliary support mechanism can obtain better support stability, thereby improving the device's ability to prevent slope collapse.

[0046] In some embodiments, elastic layers 19 made of rubber are disposed at both the upper and lower ends of the retaining plate 4 .

[0047] During specific use, there is a certain stress relief between the retaining plates 4 on the same support column 1 when they are compressed, and hard slipping is also prevented.

[0048] In other embodiments, the outer sides of the rotating cone head and the support column 1 are provided with anti-slip grooves to increase the tensile strength of the support column 1 .

[0049] Specific use principle: First, the staff nails the support column 1 into the corresponding position of the foundation pit, and makes the slide 3 face the direction of the slope, then overlaps and installs the retaining plate 4 on the support column 1 through the sliding mechanism, and presses and installs the retaining plate 4 through the pressing mechanism, and then uses the same method to install another support column 1 to other corresponding positions of the foundation pit, and then connects two adjacent retaining plates 4 through the detachable connecting mechanism; the other side of the support column 1 is improved by the auxiliary support mechanism.
