Example Embodiment

[0021] Embodiment: The road shoulder composite retaining structure in this embodiment is used in the construction of reinforcing the width of the high slope roadbed. Such as figure 1 As shown, the high slope subgrade is axisymmetric with the subgrade center line 12, figure 1 The middle and right side roadbed is complete, and the left boundary part 17 of the road design on the left side is a side slope with insufficient width. It is necessary to fill the rock and soil 9 at this side to meet the needs of roadbed construction, that is, to complete the width of the left boundary 17 part of the road design . The side slope is divided by the side slope ground line 16, above the side slope ground line 16 is the rock and soil mass 9 to be filled, and below the side slope ground line 16 there are residual slope soil 13, weathered rock layer 14, and supporting rock layer 15. Since the surface of the weathered rock layer 14 is an inclined surface (slip surface), and the surface of the res...

Abstract

The invention relates to the technical field of civil engineering, in particular to a road shoulder composite retaining structure, which is characterized in that: the retaining structure at least includes micro piles, buttress-type retaining walls, connecting beams, anchors, and earth retaining boards, wherein The micro piles are arranged at intervals along the road direction of the high slope embankment, the micro piles are used as the pile foundation of the buttress retaining wall, the top of which is rigidly connected to the bottom of the buttress retaining wall, the The connecting beam is arranged at the lower position where the micropile is rigidly connected with the buttress retaining wall, one end of the anchor is connected and fixed with the connecting beam, and the other end is inserted into the rock mass of the slope, and the retaining plate Lap between adjacent micropiles. The invention has the advantages of: it can make up the under-width of road embankments in mountainous areas, and at the same time make up the rock-soil mass and slope to play the role of reinforcement and support, and has the advantages of light weight, easy construction, material saving, environmental protection, safety, and construction period saving. .

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a road shoulder composite retaining structure. Background technique [0002] A shoulder is the edge of a road embankment. The road shoulder retaining structure is a structure used to strengthen and support the unstable rock and soil mass at the edge of the road subgrade. The unstable rock and soil mass of the road shoulder and slope includes the unstable rock and soil mass caused by road construction and excavation and the unstable rock and soil mass that is filled with insufficient width of the roadbed, especially for the road shoulder located on a higher slope, and the width of the roadbed is Insufficient engineering conditions that need to be filled. [0003] General slope retaining structures include gravity retaining walls, cantilever retaining walls, buttress retaining walls, anchor bar anchor plate retaining walls, row piles and reinforced retaining walls. The...
