Problems solved by technology

The first type of red sandstone has low compressive strength, disintegrates in the form of mud or slag, and has poor water stability and strength stability, which is close to or belongs to weak expansive rock; the second type of red sandstone disintegrates in massive form, with water stability and strength Good stability, no obvious expansion; the third type of red sandstone has high strength and is difficult to disintegrate naturally
When red sandstone is used as filler, it may cause embankment deformation, strength attenuation and other phenomena, resulting in road surface settlement

Embodiment Construction

[0039] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0040] Such as figure 1 As shown, a red sandstone subgrade includes a base body 1 and slope modules 2 located on both sides of the base body 1. The left and right sides of the base body 1 are restricted by the side slope modules 2, making the overall structure of the base body 1 more stable.

[0041] Such as figure 1 and figure 2 As shown, the slope module 2 includes a bottom module 3 and a top module 4 formed by concrete pouring, and each bottom module 3 includes two bottom panels 5 and a bottom side panel 6 extending upward on the opposite side of the two bottom panels 5 , the two bottom side plates 6 are inclined upward toward the opposite side, the side of the two bottom side plates 6 facing away from each other is the outer side, and the opposite side is the inner side. The interior of the two bottom side panels 6 is embedded with a bottom waterproof...

Abstract

The invention relates to the technical field of road construction, in particular to a red sandstone roadbed and a construction method thereof. The red sandstone roadbed comprises a matrix and side slope modules located on two sides of the matrix, wherein the side slope modules comprise bottom layer modules and top layer modules; each bottom layer module comprises two bottom layer plates and bottomlayer side plates located on the deviating sides of the two bottom layer plates and extending upwards; bottom layer waterproof cloth disposed along a vertical direction is embedded in the bottom layer side plates; the top layer modules comprise top layer plates and top layer side plates located on the deviating sides of the two top layer plates and extending upwards; and top layer waterproof cloth disposed along the vertical direction is embedded in the top layer side plates. The matrix is reinforced by arranging the side slope modules on two sides of the matrix, so that the matrix is more stable. The bottom layer waterproof cloth and the top layer waterproof cloth are respectively arranged in the bottom layer side plates and the top layer side plates to enable the bottom layer modules and the top layer modules to play the waterproof effect, so as to avoid pavement settlement caused by disintegration of red sandstones as rainwater seeps into and enters the red sandstones.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a red sandstone roadbed and a construction method thereof. Background technique [0002] Red sandstone has the duality of "rock and soil" and "rock". The uniaxial saturated compressive strength of red soft rock ranges from 0 to 52.6Mpa, generally less than 30MPa, mainly including mudstone, argillaceous siltstone, silt Mudstone, shale, etc. The first type of red sandstone has low compressive strength, disintegrates in the form of mud or slag, and has poor water stability and strength stability, which is close to or belongs to weak expansive rock; the second type of red sandstone disintegrates in massive form, with water stability and strength It has good stability and no obvious expansion; the third type of red sandstone has high strength and is difficult to disintegrate naturally. When red sandstone is used as filler, it may cause embankment deformation, strength atte...
