Problems solved by technology

[0004] 1) The amount of masonry and the high cost of arched slope protection with masonry rubble;
[0005] 2) Due to the arched slope protection of mortar rubble, there is not enough thickness of soil for plant growth or the root system of plant growth is unstable, so it is impossible to effectively green the embankment slope;
[0006] 3) It is not suitable for slopes with large slopes, so that the slopes occupy more land

[0045] Such as Figure 1-3 As shown, the embodiment of the present invention provides a railway embankment, the two sides of the railway embankment include side slopes and fillers between the two side slopes of the railway embankment. said figure 1 , figure 2 with image 3 Indicates the situation of different slope ratios, where image 3 It is a high and steep slope, and the slope ratio can reach 1:0.5.

[0046]Wherein, the slope includes geocells 11 , support columns 21 and toe walls 31 . The geocells 11 are stacked from bottom to top. The cell chamber of the geocell 11 is filled with roadbed filler 41 . The middles of the two geocells 11 adjacent up and down are filled with roadbed filler 41 of preset height. The upper end of the support column 21 is fixed on the bottom of the geocell 11 , and the lower end of the support column 21 is inserted into the subgrade filler 41 below the geocell 11 . The toe wall 31 is located under the side of the lowest geocell 11 . Spe...

[0054] In order to better understand the railway embankment, the construction process of the railway embankment is introduced below, and the process includes the following steps:

[0055] Step 501: Build the toe wall 31 on the ground. Both sides of the roadbed are built, and the distance between two toe walls 31 is the width of the roadbed. Specifically, M10 mortar rubble is used for the toe wall. In this way, it is more solid. Before building the toe wall, the site conditions should be leveled to ensure that the subgrade site is flat and even. The leveling of the site and the construction of the foot wall are the same as the conventional method.

[0056] Step 502 : Fill the roadbed filler 41 between the two toe walls 31 . The roadbed filler 41 filled between the two toe walls 31 needs to be higher than the toe walls 31 by a certain height. In this way, the geocells 11 will not be laid too densely in the height direction, thereby reducing the cost.

[0057] Step 503 : st...

Abstract

The invention discloses a slope of a railroad bed, the railroad bed and a construction method. The slope of the railroad bed comprises earthwork standard rooms with a preset number and stacked from bottom to top, and support columns fixed in the earthwork standard rooms; the earthwork standard rooms are filled with roadbed fillers; the roadbed fillers with preset heights are filled between the upper and lower adjacent earthwork standard rooms; the upper ends of the support columns are fixed at the bottoms of the earthwork standard rooms; and the lower ends of the support columns are inserted in the roadbed fillers under the earthwork standard rooms. The slope of the railroad bed, the railroad bed and the construction method can reduce the cost, realizes effective afforestation, and reduceoccupied lands.

Description

technical field [0001] The invention relates to the field of railway roadbeds, in particular to a slope of a railway roadbed, a railway roadbed and a construction method. Background technique [0002] With the increase of ordinary people's travel and the development of railway technology, there are more and more high-speed trains and corresponding high-speed railways. [0003] In order to ensure the safe and smooth operation of high-speed railway trains, the subgrade should have sufficient strength, stability and durability. For this reason, the side slope of the subgrade also needs to have sufficient stability. In the prior art, the side slope is often protected by geogrid + masonry rubble arched water-cutting skeleton. But this structure has the following disadvantages: [0004] 1) The amount of masonry and the high cost of arched slope protection with masonry rubble; [0005] 2) Due to the arched slope protection of mortar rubble, there is not enough thickness of soil ...
