[0002] At present, due to the limitation of route selection, some roads and railways often encounter some high slopes that are difficult to cross. At this time, using high fill embankments to solve this problem is a more economical and environmentally friendly treatment method. However, due to the large filling area and earthwork volume, the fill soil is difficult to compact, resulting in a decrease in the overall strength of the entire fill embankment, making it difficult to maintain overall stability. It is usually necessary to set a support structure at the foot of the slope to enhance the stability of the slope.
[0003] There are many existing slope protection methods, including anti-slide piles, stone masonry and retaining walls. Although the above methods can improve the stability of the slope to a certain extent, the construction is complicated and the strength requirements of the slope protection structure are high, which leads to the over-large size of the slope protection structure and excessively high project costs.

[0028] This embodiment provides a slope embankment push-type landslide control structure, such as Figure 1 As shown in the figure, the arc dotted line represents the potential sliding surface, and the control structure includes an embankment slope 1. A construction ditch 2 parallel to the extension direction of the bottom slope foot is arranged at the foot of the embankment slope 1. The construction ditch 2 is located at the bottom of the potential sliding surface of the embankment slope 1. An assembled pile plate 3 is arranged in the construction ditch 2. The bottom of the assembled pile plate 3 is inserted into the soil, and the upper part thereof extends along the axial direction of the construction ditch 2. Backfill material 4 is arranged between the construction ditch 2 and the assembled pile plate 3.
[0029] In this embodiment, the depth of the construction trench 2 is the distance from the slope surface to the potential sliding surface of the embankment slope 1, and its width is 2m.
[0030] like Figure 2 and Figure 3 As shown, the assembled pile plate 3 includes multiple, adjacent assembled pile plates 3 are plugged into each other, including inserted piles, vertical plates 31, horizontal plates 32 and triangular plates 33. The height of the vertical plate 31 is 1m, the thickness is 20cm, the length in the horizontal direction is 5m, and it is set perpendicular to the ground. The thickness of the horizontal plate 32 is 20cm, the width is 1.5m, and the length is 5m. It is fixed to the bottom of the vertical plate 31 away from the side of the embankment slope 1. The triangular plate 33 is set between the vertical plate 31 and the horizontal plate 32. The length of the vertical right-angle side is 1m, the horizontal right-angle side is 1.5m, and the thickness is 20cm. The inserted pile is set at the bottom of the horizontal plate 32.
[0031] The inserted pile includes a pile head 34 and a pile body 35. The bottom of the pile head 34 is tapered to facilitate the insertion of the pile head 34 into the soil. The cross section of the pile body 35 is rectangular and fixedly connected to the top of the pile head 34. The rectangular pile body 35 has a side length of 20 cm and a length of 4-6 m. The entire inserted pile is located at the lower part of the entire slope protection structure, passes through the potential sliding surface of the embankment slope 1, and an inserted pile is arranged at intervals of 5 m along the horizontal direction of the foot of the embankment slope 1.
[0032] In this embodiment, the assembled pile plate 3 is a prefabricated component, which is formed by integrally casting concrete in a factory with inserted piles, vertical plates 31, horizontal plates 32 and triangular plates 33.
[0033] like Figure 3 As shown, adjacent assembled pile plates 3 are connected to each other by plugging and inlaying, and adjacent assembled pile plates 3 are provided with expansion joints with a width of 0.5 cm.
[0034] In this embodiment, the backfill material 4 includes backfill soil and crushed stone, and the crushed stone is laid on the top of the backfill soil.
[0035] The construction steps of the governance structure in this embodiment are as follows:
[0036] Step S1, tidy up the foot of the slope, remove the debris on the surface of the foot of the slope, and arrange the road and the machine material storage area;
[0037] Step S2: Materials and machinery are brought in to the construction site. The assembled pile panels 3 are transported from the factory to the construction site. Machinery teams are brought in to the construction site and placed according to the plan layout.
[0038] Step S3, using an excavator to dig at the foot of the slope, digging a construction trench 2 with a width of 2m and a depth equal to the distance from the slope surface to the potential sliding surface of the slope, and placing retaining boards with smooth surfaces on both sides of the construction trench 1 close to the embankment slope 1 for support;
[0039] Step S4, using a total station to lay out the center point of each inserted pile according to the design drawings, laying out the four corner points of each inserted pile, determining the exact position of the pile hole and making positioning marks, after the layout is completed, the mutual positions of the adjacent hole piles are distanced and the pile positions are checked;
[0040] Step S5, the pile driver is in place to lift the assembled pile plate 3 to the position of the inserted pile determined in step S4, and the position is checked, and then the pile is pressed, and the inserted pile is pressed into the designed marked position, and the pile position is checked again;
[0041] Further, the marking line position is to draw a marking line at a depth of 1.5m from the top of the vertical plate 31 on the inserted pile;
[0042] Step S6: Repeat step S5 to press the piles at the position of the pile driver until all the assembled pile plates 3 are pressed into the designed positions according to the design drawings;
[0043] Step S7, pull out the retaining plate placed in step S3, then backfill the construction trench 2 and lay a layer of crushed stone on the surface of the residual soil filled in above.
[0044] Compared with the existing mortar-laid block stone retaining wall and cast-in-place reinforced concrete gravity retaining wall, the management structure in this embodiment reduces the large-scale excavation of the embankment slope 1 during construction, thereby not causing further disturbance to the stability of the original embankment soil, destroying the stress balance state of the original soil, and avoiding the possibility of instability and damage to the original high slope; and the use of prefabricated components for direct on-site hoisting construction is simple, the construction period is short, and the project cost is low.
[0045] The assembled pile plate 3 in this embodiment is provided with a vertical plate 31, a horizontal plate 32 and a triangular plate 33, which can transfer the shear force and bending moment generated by the slope soil to the horizontal plate 32 through the vertical plate 31 and the triangular plate 33, and convert them into pressure on the soil, thereby effectively dealing with the shear force and bending moment generated by the slope soil. At the same time, the assembled pile plate 3 is provided with prestressed steel bars inside, which can effectively resist part of the tensile force caused by the bending moment, thereby avoiding damage to the structure due to resistance to excessive shear force and bending moment. Compared with the existing structure, the structural size is reduced, thereby reducing the project cost.
[0046] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
