Abstract

A kind of landslide o earth slope consolidation roadbed of high-speed structure meets the needs that high-speed railway subgrade engineering is built on slip mass effectively to control landslide o earth slope body stability and deformation.Longitudinally, laterally setting cement fly ash gravel pile in interval forms reinforcing body in the slip mass below road structure, and the lower part of each cement fly ash gravel pile passes through sliding surface and enters steady soil certain depth.On the upside of reinforcing body, longitudinally spaced setting reinforcing pile in the slip mass of downside, the lower part of reinforcing pile is passed into sliding surface and enters steady soil certain depth.The top of reinforcing body is laid with bed course, and road structure is constructed on bed course.

Description

A kind of landslide o earth slope consolidation roadbed of high-speed structure
Technical field
The utility model relates to geotechnical engineerings, in particular to landslide o earth slope consolidation roadbed of high-speed structure.
Background technique
Landslide is largely distributed in Southwestern China mountain area, when the good ground of certain depth under slip mass and sliding surface is soil property When, high-speed railway subgrade engineering how is built on slip mass and has easy for construction, economical, while meeting high-speed railway to steady Qualitative and deformation requirement, therefore need to propose a kind of landslide o earth slope consolidation roadbed of high-speed structure, and should have safe and environment-friendly The features such as.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of landslide o earth slope consolidation roadbed of high-speed structure, with Effectively control landslide o earth slope body stability and deformation meet the needs that high-speed railway subgrade engineering is built on slip mass.
It is as follows that the utility model solves the technical solution that above-mentioned technical problem is taken:
A kind of landslide o earth slope consolidation roadbed of high-speed structure, including road structure, it is characterized in that: under the road structure Longitudinally, laterally setting cement fly ash gravel pile in interval forms reinforcing body in the slip mass of side, each cement fly ash gravel pile Lower part passes through sliding surface and enters steady soil certain depth;On the upside of the reinforcing body, longitudinally spaced setting in the slip mass of downside Reinforcing pile, the lower part of reinforcing pile are passed into sliding surface and enter steady soil certain depth;The top of the reinforcing body is laid with bed course, Road structure is constructed on bed course.
The utility model has the beneficial effects that effectively control landslide o earth slope body stability and deformation, is able to satisfy in slip mass On build the needs of high-speed railway subgrade engineering;Construction is simple, construction investment is low, and meets the requirement of environmental protection, has to promote and answer Use prospect.
Detailed description of the invention
This specification includes following two width attached drawing:
Fig. 1 is a kind of sectional schematic diagram of landslide o earth slope consolidation roadbed of high-speed structure of the utility model.
Fig. 2 is the structural schematic diagram of bed course in a kind of landslide o earth slope consolidation roadbed of high-speed structure of the utility model.
Component name and corresponding label: cement fly ash gravel pile 1, reinforcing pile 2, bed course 3, lower rubble are shown in figure Layer 31, upper metalling 33, lower TGXG 34, upper TGXG 35, road structure 4, slip mass A, stablizes soil at medium stone layer 32 Layer B, sliding surface C.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
Referring to Fig.1, a kind of landslide o earth slope consolidation roadbed of high-speed structure of the utility model includes road structure 4.Institute It states and is longitudinally, laterally spaced the setting formation reinforcing body of cement fly ash gravel pile 1, each cement in the slip mass A of 4 lower section of road structure The lower part of flyash gravel pile 1 crosses into sliding surface C and enters steady soil B certain depth.The cunning of the reinforcing body upside, downside Longitudinally spaced setting reinforcing pile 2 in slopes A, the lower part of reinforcing pile 2 cross sliding surface C and enter steady soil B certain depth.It is described The top of reinforcing body is laid with bed course 3, and road structure 4 is constructed on bed course 3.It is described to be set on the upside of reinforcing body in slip mass A Reinforcing pile 2 is set to the reinforcing pile 2 on the downside of reinforcing body in slip mass A and is used small bore stake using big section stake.
Referring to Fig.1, the utility model using (CFG) the reinforcing slip mass A of cement fly ash gravel pile 1 and enters stabilization Soil layer B certain depth solves the problems, such as that the landslide soil body generates Vertical Settlement, CFG technology maturations, warp under upper load effect Ji property is good, and CFG pass through sliding surface C and can increase skid resistance;Using be arranged on the upside of reinforcing body, the reinforcing pile 2 of downside stablize slide Slopes A, so that the high-speed railway built on slip mass A has enough stability, upside reinforcing pile 2 uses big section stake, Size, which is subject to, meets resistance sliding force size at stake position, and lower side uses small bore stake, migrates shadow to avoid downside slip mass It rings.Using bed course 3 as the buffer layer between reinforcing body and top road structure 4, make cement fly ash gravel pile 1 and top Uniformly, road structure 4 is basic as the carrying of high-speed railway for structure stress deformation.It is steady that the structure efficiently solves landslide o earth slope body The problem of qualitative and strict control deformation, be able to satisfy and build high-speed railway subgrade engineering on slip mass, and have construction is simple, The features such as construction investment is low has popularization and application foreground, and meets the requirement of environmental protection.
Referring to Fig.1, the depth that the cement fly ash gravel pile 1 enters steady soil B is typically no less than 1.0m.Referring to figure 2, the bed course 3 is by the lower metalling 31, lower TGXG 34, medium stone layer 32, the upper soil that successively fill and be laid with from below to up Work grid 35 and the compound composition of upper metalling 33, thickness are generally 0.6m.
The above only explains through diagrams the one of a kind of landslide o earth slope consolidation roadbed of high-speed structure of the utility model A little principles, be not intended to for the utility model to be confined to shown in and the specific structure scope of application in, therefore it is all it is all can The corresponding modification that can be utilized and equivalent, belong to the applied the scope of the patents of the utility model.
