Description
Technical field
The utility model is related to geotechnical engineerings, the more particularly to lower soil property cutting high-speed railway ruggedized construction of bearing capacity.
Background technology
High-speed railway is common engineering by soil property cutting, and high-speed railway requires chasm structuref foundation bearing capacity to be not less than
180kPa, and need to fill out soil property cutting changing for certain depth of progress using high quality filler or conditioned soil, to meet high-speed iron
The ride comfort on road and safety.It requires to increase changing with filling out depth or progress for foundation soil when ground low bearing capacity is in 180kPa
Base consolidation process changes that fill out depth limited and be affected by draining, for reduction train when using composite foundation stabilization wherein excavating
Influence of the dynamic stress to composite foundation needs that thicker roadbed filling body is arranged, and causes that cutting depth is big, forms cutting flash
Slope, therefore need a kind of lower soil property cutting high-speed railway ruggedized construction of new bearing capacity above-mentioned to solve the problems, such as, and
Should have the characteristics that economical, easy for construction, safe and environment-friendly.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of lower soil property cutting high-speed railways of bearing capacity to add
Fixing structure meets strength and stiffness requirement needed for high-speed railway effectively to solve low bearing capacity soil property cutting, reduces cutting and open
It digs height and foundation soil changes and fills out depth.
Technical solution is as follows used by the utility model solves above-mentioned technical problem：
The lower soil property cutting high-speed railway ruggedized construction of a kind of bearing capacity of the utility model, it is characterized in that it includes：
Compaction pile is arranged at intervals on form compound foundation in dirt road moat ground；Bed course is arranged on composite foundation surface and compacted stake top
Portion；Backing plate is arranged at the top of bed course；Roadbed bottom, is filled at the top of backing plate；Roadbed surface layer is filled at the top of roadbed bottom；Row
Water lateral sulcus is arranged in soil property chasm structuref both sides.
The utility model has the beneficial effects that efficiently solve low bearing capacity soil property cutting meet it is strong needed for high-speed railway
Degree and rigidity requirement, and the excavation height of soil property cutting can be reduced and changing for high-speed railway fills out depth, there is construction is simple, engineering
The features such as low is invested, there is popularizing application prospect, and meets the requirement of environmental protection.
Description of the drawings
This specification includes following two width attached drawing：
Fig. 1 is a kind of cross-section diagram of the lower soil property cutting high-speed railway ruggedized construction of bearing capacity of the utility model.
Fig. 2 is that the structure of bed course in a kind of lower soil property cutting high-speed railway ruggedized construction of bearing capacity of the utility model is shown
It is intended to.
Component name and corresponding label are shown in figure：Compaction pile 1, bed course 2, lower improvement soil layer 21, lower TGXG
22, middle improvement soil layer 23, middle TGXG 24, upper improvement soil layer 25, backing plate 3, roadbed bottom 4, roadbed surface layer 5, draining lateral sulcus
6, soil property cutting ground A.
Specific implementation mode
The utility model is further illustrated with reference to the accompanying drawings and examples：
Referring to Fig.1, a kind of lower soil property cutting high-speed railway ruggedized construction of bearing capacity of the utility model includes：Compaction pile
1, it is arranged at intervals on form compound foundation in dirt road moat ground A；Bed course 2, setting is at 1 top of composite foundation surface and compaction pile；
Backing plate 3, setting is at 2 top of bed course；Roadbed bottom 4 fills at 3 top of backing plate；Roadbed surface layer 5 is filled and is pushed up in roadbed bottom 4
Portion；Lateral sulcus 6 is drained, is arranged in soil property chasm structuref both sides.
Referring to Fig.1, the utility model increases foundation capability with the pile strength of compaction pile 1, and can ground compaction soil
Form compound foundation, to reach the strength and stiffness for improving low bearing capacity foundation soil, to meet high-speed railway to foundation requirement.
Compaction pile 1 makes construction using lime or Cement Soil, pile body have certain flexibility to superstructure with preferably by
Power compatibility of deformation.
With reference to Fig. 2, the bed course 2 by fill and be laid with successively from below to up lower improvement soil layer 21, lower TGXG 22,
Middle improvement soil layer 23, middle TGXG 24 and upper 25 compound composition of improvement soil layer, thickness are generally 0.4-0.6m.Utilize bed course 2
As the buffer structure at 1 top of compaction pile, keep compaction pile 1 and superstructure stress deformation uniform, conditioned soil can separate knot up and down
Water contact channel between structure, it is ensured that foundation soil strength is unaffected.
Referring to Fig.1, backing plate 3 is formed using reinforced concrete cast-in-situ, the general 0.2-0.3m of thickness, passes through the big rigid of backing plate 3
Train dynamic stress has an impact composite foundation when degree can use relatively thin constructing soil to avoid upper part, reduces upper part constructing soil
Thickness can save the usage amount of high-quality roadbed filling, and can reduce to foundation soil cutting depth, while reduce cut slope
Excavation height.
Referring to Fig.1, the basic stress structure of roadbed bottom 4 and roadbed surface layer 5 as train rail, roadbed bottom 4 are set
The too small property green powder of roadbed surface layer 5 can be reduced by setting, while can be reduced top dynamic load and be acted on the punching of backing plate 3, from
And reduce the setting thickness of backing plate 3.The quickly discharge surface water of lateral sulcus 6 is drained, the influence to earthen foundation is reduced.Roadbed bottom 4
It is filled using AB groups filler or conditioned soil, thickness 0.5-1.0m.Roadbed surface layer 5 uses graded broken stone filling technology, Ballast track high
5 thickness of roadbed surface layer of fast railway is 0.7m, and 5 thickness of roadbed surface layer of non-fragment orbit high-speed railway is 0.4m.
