Embodiment Construction

[0009] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings.

[0010] refer to figure 1 , the trinity structure of the high-speed railway sound barrier, catenary and cutting support of the present invention includes the sound barrier and the catenary support 3 arranged between the high-speed railway cutting F and the residential area J. The sound barrier is a cantilever sound barrier retaining wall 1 with an L-shaped section, which has an upright cantilever 1.1 and a bottom plate 1.2 extending into the high-speed railway cutting F. On the inner side wall of the cantilever 1.1, corbels 2 are arranged at intervals along the line extension direction, and catenary pillars 3 are arranged on the corbels 2 . A backfill layer 4 is provided on the outside of the cantilever sound barrier retaining wall 1 . The cantilever sound barrier retaining wall 1 can be used as the supporting structure of the high-speed r...

Abstract

The invention discloses a sound barrier, a catenary and a road cut supporting structure into one unit of a high-speed railway, and then the technical problems faced by urban residential areas near thehigh-speed railway such as the limited land area, strict noise control and saving project investment and the like can be solved. A sound barrier arranged between the high-speed railway road cut and the residential area and a catenary pillar are comprised. The sound barrier is a cantilever sound barrier retaining wall with an L-shaped cross-section. And the sound barrier is provided with a vertical cantilever and a bottom plate which extends into the road cut of the high-speed railway. A corbel structure is arranged at intervals at the inner wall of the cantilever along the direction of road extension. The catenary pillar is arranged on the corbel structure. A backfill layer is arranged outside the cantilever sound barrier retaining wall.

Description

technical field [0001] The invention relates to the technical field of high-speed railway embankment, in particular to a three-in-one structure of a sound barrier, a catenary and a cutting retainer. technical background [0002] High-speed railways close to urban residential areas have strict noise control requirements, and face a series of problems such as limited railway land in urban areas and narrow construction space, especially shallow cutting projects. In this regard, if the high-speed railway passes through urban residential areas through bridges or tunnels, the railway line needs to be raised or lowered, which will easily lead to a substantial increase in investment in projects along the line; Structures such as catenary, catenary and roadbed support, etc., if these structures are arranged sequentially in the cross-sectional direction, the land use range of the railway roadbed will be significantly increased. In order to solve the above problems, it is urgent to pr...
