[0034] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0035] Foamed lightweight soil is a new lightweight and environmentally friendly filling material. Its main characteristics are that its bulk density is smaller than that of ordinary soil, while its strength and deformation characteristics can reach or even exceed those of good soil. It has the advantages of light weight, good fluidity, self-supporting after solidification, and no need for mechanical rolling and vibration during construction. Using it as a road embankment can effectively solve the world's common quality problems such as vehicle jumping at the bridge head, external bulging or even span collapse of high fill retaining walls, differential settlement of widened new and old embankments, frost heaving and slurrying of embankments in cold regions, and environmental damage caused by high fill and deep excavation.

[0036] Embankment formwork is a formwork used for embankment filling construction, usually made of materials such as steel plates, wooden boards or plastic boards. Its main function is to provide a stable support and shape for the fill during the embankment filling process to ensure the stability and quality of the embankment.

[0037] The existing embankment formwork is usually designed as a separate body from the supporting assembly. It is very easy to lose during transportation, resulting in a waste of resources. The separate design is not conducive to assembly, which affects the construction efficiency. The foam lightweight soil backfill embankment formwork provided by the present application has a supporting assembly 2 and a formwork 1 that are integrated and are not easy to lose during transportation. At the same time, after the device is unfolded, its volume is reduced, which is convenient for transportation. During installation, the supporting formwork 1 can be quickly connected, which greatly improves the construction efficiency.

[0038] The specific structure of the foam lightweight soil backfill embankment template provided in this application is described in detail below in conjunction with the accompanying drawings.

[0039] Reference Figure 1-Figure 6 As shown, an embodiment of the present application provides a foam lightweight soil backfill embankment template, comprising a template 1 and a plurality of support assemblies 2 arranged on the template 1;

The support assembly 2 is arranged in the first slot body 3 and plugged into the first slot body 3. The support assembly 2 includes a rotating plate 21 and a cylinder.

[0041] The rotating plate 21 can be a metal plate body with a certain length. The rotating plate 21 is inserted into the first trough body 3, and the bottom end of the rotating plate 21 is hinged to the inner wall of the first trough body 3. The upper part of the rotating plate 21 swings left and right. The side of the rotating plate 21 facing the template 1 is provided with a second trough body 22. The second trough body 22 can be a square trough body. The lower inner wall of the second trough body 22 is hinged with a mounting tube 23. The mounting tube 23 can be a metal tube body. The upper part of the mounting tube 23 can swing left and right.

[0042] The top end of the cylinder is hinged to the upper inner wall of the first trough body 3, and the cylinder is opposite to the second trough body 22, the cylinder is plugged into the second trough body 22, the inner wall of the cylinder is screwed with a screw 26, the diameter of the screw 26 is larger than the inner diameter of the installation cylinder 23, the outer end of the screw 26 extends out of the cylinder and is connected to an insertion rod 27, and the insertion rod 27 is plugged into the installation cylinder 23;

[0043] like Figure 2 As shown, when storing, the screw 26 is rotated clockwise, the screw 26 is stored in the cylinder, the cylinder is located in the first slot 3, and is in a vertical state under the action of its own gravity; the rotating plate 21 is rotated into the first slot 3, the installation cylinder 23 is in a vertical state under the action of its own gravity, and is located in the second slot 22, and the cylinder is plugged into the second slot 22 and is also located in the second slot 22; Figure 3 As shown, when supporting, the top of the rotating plate 21 rotates to the right to reach a horizontal state and fit the ground, the cylinder body and the mounting cylinder 23 both rotate to the right to a coaxial state, and the screw rod 26 is rotated counterclockwise, the screw rod 26 extends out of the cylinder body, so that the insertion rod 27 is inserted into the mounting cylinder 23, and the bottom end of the screw rod 26 abuts against the top end of the mounting cylinder 23, so that the cylinder body, the screw rod 26, the insertion rod 27 and the mounting cylinder 23 form an inclined support rod, which supports between the template 1 and the rotating plate 21, so that the template 1 is fixed.

[0044] Reference Figure 2-Figure 4 As shown, in some embodiments, the cylinder includes a fixed cylinder 24 and an inner spiral ring 25;

The width of the slider 29 matches the width of the slide groove 28, and the slider 29 is slidably connected to the slide groove 28.

[0047] When adjusting the screw 26, the slider 29 is slidably connected to the slide groove 28, so that the screw 26 will not rotate relative to the fixed tube 24. When the inner screw ring 25 is rotated clockwise, the screw 26 and the slider 29 move outward relative to the fixed tube 24 and the inner screw ring 25. On the contrary, when the inner screw ring 25 is rotated counterclockwise, the screw 26 and the slider 29 move inward relative to the fixed tube 24 and the inner screw ring 25, thereby preventing the screw 26 from rotating. After the insertion rod 27 is inserted into the installation tube 23, the template 1 can be stably supported.

[0048] In some embodiments, a spherical head is provided at the end of the insertion rod 27 to facilitate insertion of the insertion rod 27 into the installation tube 23 .

The two ends of the spring 43 are respectively in contact with the inner wall of the cavity and the inner end outer wall of the limiting column 42. The outer ends of the two limiting columns 42 pass through the through hole and are respectively plugged into the two limiting grooves 5.

[0055] In the natural state, the two limiting posts 42 extend out of the through holes under the action of the two springs 43 , and are respectively plugged into the limiting grooves 5 on both sides of the first groove body 3 , so that the rotating plate 21 is fixed in the first groove body 3 .

[0056] In some embodiments, the inner ends of the two limit columns 42 are each provided with a sliding plate 44, which may be a circular plate body.
