Problems solved by technology

[0002] With the development of new rural road construction in mountainous areas of our country, due to the constraints of construction funds, land acquisition and other factors, it is impossible to avoid landslides, and because of the limitation of the longitudinal slope of the line, bridges cannot be used to cross, so high embankments have to be used. Bring sliding loads to the landslide mass, often leading to embankment instability
[0003] In order to prevent embankment instability, it is necessary to set up special anti-slide piles, which is very expensive and the effect is not ideal

Embodiment 1

[0047] Embodiment 1 of the present invention is the high embankment structure built on the landslide body when the height of the embankment exceeds 10m, and the specific structure is as follows figure 1 , figure 2 and image 3 shown. It includes an upper box structure, a middle frame structure and a lower anti-slip and stable structure.

[0048] The upper box structure includes a box bottom plate 101, a box outer wall 102 and an inner partition wall 103. The box bottom plate 101 and the box outer wall 102 are poured into a hollow box structure with an upper opening, and a plurality of inner partition walls 103 are spaced vertically. Set inside the hollow box structure, the inner partition wall 103 has a rectangular structure, and the fluid state stabilized soil 104 is filled between the inner partition walls 103 . The outer wall 102 of the box is provided with expansion joints 105 over 30 meters in length. The upper part of the box structure is provided with a subgrade an...

Embodiment 2

[0054]Embodiment 2 of the present invention is the high embankment structure built on the landslide body when the embankment height is less than 10m and greater than 5m, and the specific structure is as follows Figure 4 , Figure 5 and Figure 6 shown. Including the upper box structure and the lower anti-skid stable structure.

[0055] The upper box structure includes a box bottom plate 201, a box outer wall 202 and an inner partition wall 203. The box bottom plate 201 and the box outer wall 202 are poured into a hollow box structure with an upper opening, and a plurality of inner partition walls 203 are spaced vertically. Set inside the hollow box structure, the inner partition wall 203 is a rectangular structure, and the inner partition wall 203 is filled with fluid stable soil, and the second tie rod 214 is added to the section where the height of the upper box structure exceeds 5m to improve the overall rigidity , the second tie rod 214 is located on the horizontal axi...

Embodiment 3

[0060] Embodiment 3 of the present invention is the high embankment structure built on the landslide body when the embankment height is less than 10m and greater than 5m, and the specific structure is as follows Figure 4 , Figure 5 and Figure 7 shown. Including the upper box structure and the lower anti-skid stable structure.

[0061] The structure of the third embodiment is similar to that of the second embodiment, the difference lies in the structure of the inner partition wall 303 . The inner partition wall 303 of the third embodiment is made into a triangular tie plate, and the vertex angles of two opposite triangular inner partition walls 303 in the same row are offset. Making the inner partition wall 303 into a triangular tie plate facilitates the filling of the fluid state stabilized soil 304 and the construction of the subgrade road surface rolling layer 306 in the upper box structure.

[0062] Concrete construction steps are identical with embodiment 2.

Abstract

The invention relates to the technical field of subgrade engineering, and discloses a high-embankment structure built on a sliding mass. The high-embankment structure comprises an upper box structureand a lower anti-sliding stabilizing structure. The upper box structure comprises a box bottom plate, a box outer wall and a plurality of inner partition walls. The box bottom plate and the box outerwall are subjected to concrete casting to form a hollow box structure with the open upper portion. The multiple inner partition walls are vertically arranged in the hollow box structure at intervals.A subgrade pavement rolling layer is arranged on the upper portion of the upper box structure. The lower anti-sliding stabilizing structure comprises a plurality of anti-sliding bearing piles and a pile top crown beam. The multiple anti-sliding bearing piles are vertically arranged in a stratum of the sliding mass at intervals. The pile top crown beam is arranged at the tops of the multiple anti-sliding bearing piles, and the pile top crown beam and the anti-sliding bearing piles are subjected to concrete casting into a whole. According to the high-embankment structure built on the sliding mass, the anti-sliding stability safety factor of a slope can be increased, under the situation of ensuring the safety of an embankment and the slope, the occupied area is decreased by 50% or above, andthe high-embankment structure has the good economic and ecological benefits.

Description

technical field [0001] The invention relates to the technical field of roadbed engineering, in particular to a high embankment structure built on a landslide body. Background technique [0002] With the development of new rural road construction in mountainous areas of our country, due to the constraints of construction funds, land acquisition and other factors, it is impossible to avoid landslides, and because of the limitation of the longitudinal slope of the line, bridges cannot be used to cross, so high embankments have to be used. The sliding load brought to the landslide mass often leads to the instability of the embankment. [0003] In order to prevent embankment instability, it is necessary to set up special anti-slide piles, which is very expensive and unsatisfactory in effect. There is an urgent need for an embankment form with anti-sliding function. Contents of the invention [0004] In order to solve the above-mentioned deficiencies in the prior art, the pres...
