Embodiment Construction

[0041] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0042] Such as figure 1 As shown, an anti-settlement subgrade includes a base body 1 and slope modules 2 located on both sides of the base body 1. The base body 1 sequentially includes a lower lime-soil rammed earth layer 3, a lime-soil gravel filling layer 4, and an upper lime-soil rammed earth layer from bottom to top. Layer 5 and gravel layer 6.

[0043] Such as figure 1 and figure 2 As shown, the slope module 2 includes a bottom module 7, a middle module 8 and a top module 9 formed by pouring waterproof concrete. The bottom module 7 includes a bottom plate 10 and a bottom side plate 11 located on the side of the bottom plate 10 facing away from the base body 1. The bottom side plate 11 is inclined toward the base 1 from bottom to top. Bottom positioning protrusions 12 are formed on the upper surface of the bottom side plate 11 . The middle module 8 ...

Abstract

The invention relates to the technical field of road anti-settlement, in particular to an anti-settlement subgrade and a construction method thereof. The anti-settlement subgrade comprises a base bodyand slope modules which are positioned on the two sides of the base body; each slope module comprises a bottom module, an intermediate module and a top module which are formed by pouring waterproof concrete; the bottom module comprises a bottom plate and a bottom side plate which is positioned on one side, back to the base body, of the bottom plate; the intermediate module comprises an intermediate plate and an intermediate side plate which is positioned on one side, back to the base body, of the intermediate plate; the top module comprises a top plate and a top side plate which is positionedon one side, back to the base body, of the top plate; and a waterproof layer coats between the bottom side plate and the intermediate side plate as well as between the intermediate side plate and thetop side plate. A waterproof sealing surface is formed by matching the bottom module, the intermediate module and the top module which are formed by pouring the waterproof concrete and the waterprooflayers which coat between the bottom side plate and the intermediate side plate as well as between the intermediate side plate and the top side plate, so that water flow cannot enter the base body through slopes, and the probability of settlement of the base body is reduced.

Description

technical field [0001] The invention relates to the technical field of road subsidence prevention, in particular to an anti-subsidence subgrade and a construction method thereof. Background technique [0002] Subgrade refers to a belt-shaped structure built according to the route position and certain technical requirements as the foundation of the road surface. It is a linear structure built with soil or stone. In terms of materials, roadbeds can be divided into soil roadbeds, stone roadbeds, and earth-rock roadbeds. Roadbeds built under good geological, hydrological and climatic conditions are the foundation of railways and roads, and are directly related to whether railways and roads can be used normally. [0003] The stability of the subgrade is easily reduced due to the influence of surface water, groundwater, capillary water and frost heaving, which leads to problems such as subgrade settlement, which seriously affects the normal operation of traffic. Contents of the ...
