Abstract

The present invention purchases and installs an arc-zigzag-type retaining wall on the left and right slopes of the roadbed, and the retaining wall is equipped with a horseshoe-type retaining wall unit block with a high cloud on the middle part and a low cloud on the left and right ends. The unit block and block are connected in a wave shape to prevent ground collapse of railroads and plant various trees and plants to provide environmentally friendly railroads.

Description

A block retaining wall for a railroad roadbed protection}

The present invention is to provide a retaining wall for the rail roadbed to keep the rail and sleepers laid safely by absorbing and exhausting the load and vibration applied to the rail when the train is running in the railroad in which the railroad is laid, As a design for a retaining wall structure that can be installed as a block having a structure for easy installation, conventional railroads install gravel in a range of a predetermined height and width from the existing ground, and then the lower portion is embedded in the gravel layer on the upper surface of the gravel layer. The sleepers made of wood or concrete to be fixed are laid at right angles to the longitudinal direction of the roadbed at predetermined intervals, and then the rails on which the sleepers and the rails of the train run are fastened and fastened with rail fastening clips. A railroad roadbed is laid.

The railroads laid in the above structure are laid in the same structure even when they pass through the city section, so the railway repairman always keeps the tracks around the railroads so that the landscape around the railway is very depressed and the roadbed of the gravel is not lost. There is a problem that requires monitoring and maintenance.

The present invention is designed to produce concrete blocks of constant size and arc shape on the left and right road slopes in order to maintain a more stable railway roadside while maintaining the environment-friendly beautification structure when the railway passes through the city center. In order to form the retaining wall by laying in the longitudinal direction of the rail, and planted on the retaining wall slope, devised to beautified to the environment surrounding the environmentally friendly railway, bar in detail according to the accompanying drawings as follows.

While the retaining wall 10 is embedded in the longitudinal direction of the railway, the unit structure of the concrete retaining wall 10 is planarly embedded at the tip of the left and right roadbeds (2) (2a) inclined surfaces of the railway, which is a gravel layer constituting the railway line (1). Has a predetermined thickness and has a border (11) of a constant radius of horse (horse) form, but the border 11 of the rail side is formed to be inclined with a low cloud head (12) high and the roadbed tip, such a border (11) The tip is a circular arc surface in the opposite direction of the rim 11, is a half arc of the radius of the rim 11, left and right symmetrical with respect to the center of the rim 11, and both sides of the rim 11 are the lowest A plurality of bolt through holes 13 are laid at the ends 11a and 11b, and the steel plate fixing plate bent in an arc on the wall surface before and after the edge 11a on both sides 11a. 14) Retains the retaining wall 10 by welding 14a and attaching and screwing it with the bolt 15 and the nut 16. High-applied to the inclined surface relative to the retaining wall by planting a tree (20) and plants such as the US and railway roadbed around.

By placing beautiful retaining trees and plants on the slope of the roadbed by installing the wave-shaped retaining wall 10 around the railway, which is implemented according to the present invention, which is configured as described above, the surrounding environment of the railway can be very beautiful and can be provided as a friendly place. As the retaining wall 10 supports the roadbed slope, an accident such as road collapse does not occur.

Claims (1)

In constructing the railway roadbed, the concrete retaining wall 10 is embedded in the left and right roadbeds (2) and (2a) of the track in the lengthwise direction of the track, but the unit structure of the retaining wall 10 has a predetermined thickness in plan and is finished. (馬蹄) shape has a border (11) having a constant radius, but the rail (11) of the rail side is formed to be inclined with a low head (12) high and roadbed to the front end, and this edge (11) the tip of the border (11) Both ends 11a and 11b of the edge 11, which are circular arc faces in the opposite direction, become 1/2 arcs of the radius of the edge 11, are symmetrical left and right with respect to the center of the edge 11, and become the lowest motto. A plurality of bolt through holes 13 are laid in the wall, and the steel plate fixing plates 14 and 14a, which are curved by arcs on the wall surfaces before and after the edge 11, on both sides of the front end 11a, are treated with bolts 15 and nuts ( The retaining wall 10 is constructed by attaching and fixing in a fixed manner, and the inclined surface is covered based on the retaining wall. No-rail protective subgrade retaining wall block that is hayeoseo food material or the like 20 and the plants
