Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] refer to figure 1 , the railway high-fill embankment box structure of the present invention includes reinforced concrete box-shaped segments arranged continuously along the embankment extension direction, and each reinforced concrete box-shaped segment is integrally poured from a top plate 21, a bottom plate 22, and two side webs 23 , the base plate 22 sand is located on the cushion layer 30; the lateral ends of the top plate 21 and the bottom plate 22 respectively extend out from the webs 23 on the same side to form an overhang structure, and the width of the bottom plate 22 and the top plate 21 exceeds the width of the webs 23 on both sides. spacing. On the top plate 21, the bottom layer 11 of the foundation bed and the surface layer 12 of the foundation bed are sequentially constructed from bottom to top.

[0019] refer to figure 1 , Compar...

Abstract

The invention provides a railway high-fill embankment box structure, which can effectively improve the overall rigidity of the box structure, effectively meet the safety and stability requirements ofrailway high embankment slope, at the same time, solve the durability problem of embankment structure, reduce the differential settlement of foundation, and adapt to the requirements of foundation bearing capacity. Comprises continuously arranged reinforced concrete box-shaped segments along the extension direction of the embankment, wherein each reinforced concrete box-shaped segment is integrally poured from a top plate, a bottom plate and two web plates on both sides, and the bottom plate sand is seated on a cushion layer; The two transverse ends of the top plate and the bottom plate respectively extend out the same side webs to form an outer overhanging structure, and the bottom layer of the base bed and the surface layer of the base bed are sequentially constructed from the bottom tothe top of the top plate.

Description

technical field [0001] The invention relates to a railway embankment structure, in particular to a novel high-fill embankment structure aimed at areas with strict restrictions on land use and lack of stone materials. Background technique [0002] With the vigorous development of my country's railway construction, the requirements for economy and adaptability are getting higher and higher in the construction process. Especially in places where the topography is limited and the properties of the structure are limited, such as the conditions where the slope of the high fill embankment at the bridgehead is limited. In the above situation, if the scheme of extending the bridge section or adopting the gravity (balanced weight) retaining wall to close the slope will inevitably increase the large investment, and the gravity (balanced weight) retaining wall has higher requirements on the bearing capacity of the foundation. Therefore, in order to reduce investment, meet the applicabi...
