The reinforcing structure comprises reinforced concrete bored piles (4), reinforced concrete tie beams (5), a reinforced cushion (6) and a soil roadbed (3), wherein the reinforced concrete bored piles (4) are arranged at intervals in the transverse and longitudinal directions of the roadbed of a soft foundation; the reinforced concrete tie beams (5) are in a transversely and longitudinally staggered lattice shape, and the junctions of the reinforced concrete tie beams (5) are fixedly connected with the tops of the reinforced concrete bored piles (4); the reinforced cushion (6) is paved above the reinforced concrete tie beams (5); and the soil roadbed (3) is filled above the reinforced cushion.
Description
Technical field
The utility model relates generally to railway, the flabbiness ground strengthened building method of highway, particularly the flabbiness ground strengthened structure of tilted stratum top existence.
Background technology
High-speed railway has all proposed new requirement to high ride, stability, the durability of circuit; On the tilted stratum soft foundation, build roadbed and have problems such as resistance to overturning is poor, settlement amount after construction big, horizontal sedimentation is inhomogeneous; This problem is more outstanding when particularly having soft foundation on tilted stratum top; Therefore; A kind of globality of active demand is strong, stability and good endurance, distortion is little and the flabbiness ground strengthened structure of the simple high-speed railway tilted stratum of construction technology, and meets environmental protection requirement.
The utility model content
The utility model technical problem to be solved provides the flabbiness ground strengthened structure of a kind of high-speed railway tilted stratum, has that globality is strong, good stability, distortion be little, and construction technology is simple, can effectively reducing the construction costs.
It is following that the utility model solves the technical scheme that its technical problem adopted:
The flabbiness ground strengthened structure of high-speed railway tilted stratum of the utility model is characterized in that it comprises: reinforced concrete bored pile,, longitudinal separation setting horizontal along the soft foundation roadbed; The steel concrete binder is horizontal and vertical staggered clathrate, and the top of its node position and reinforced concrete bored pile is affixed; Reinforcement cushion is layed in steel concrete binder top; Soil subgrade fills on reinforcement cushion.
The beneficial effect of the utility model is; Make full use of reinforced concrete bored pile and solve roadbed settlement after construction and horizontal uneven subsidence; Utilize the steel concrete binder to connect reinforced concrete bored pile stake jacking row; The reinforced concrete bored pile structural strength is increased, increase the resistance to overturning of soft foundation on the tilted stratum; The soil subgrade distortion that utilizes reinforcement cushion to make to fill is more even.This ground stabilization structure has that globality is strong, good stability, distortion are little, and construction technology is simple, can effectively reducing the construction costs, and compliance with environmental protection requirements, have wide popularizing application prospect.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
See figures.1.and.2, the flabbiness ground strengthened structure of high-speed railway tilted stratum of the utility model comprises: reinforced concrete bored pile 4, and, longitudinal separation setting horizontal along the soft foundation roadbed are passed soft stratum 2 entering bottoms and are held power stratum 1 enough degree of depth; Steel concrete binder 5 is horizontal and vertical staggered clathrate, and the top of its node position and reinforced concrete bored pile 4 is affixed; Reinforcement cushion 6 is layed in steel concrete binder 5 tops; Soil subgrade 3 fills on reinforcement cushion.Make full use of reinforced concrete bored pile 4 and solve roadbed settlement after construction and horizontal uneven subsidence; Utilize steel concrete binder 5 to connect 4 jacking row of reinforced concrete bored pile; Reinforced concrete bored pile 4 structural strengths are increased; Increase the resistance to overturning of soft foundation on the tilted stratum, the soil subgrade distortion that utilizes reinforcement cushion 6 to make to fill is more even.This structure has that globality is strong, good stability, the little characteristics of distortion, and construction technology is simple, can effectively reducing the construction costs, and compliance with environmental protection requirements, therefore has wide popularizing application prospect.
The length that the main reinforcement of said reinforced concrete bored pile 4 all stretches in the steel concrete binder 5 is no less than 0.5m, and affixed with the 5 main muscle colligations of steel concrete binder.With reference to Fig. 3, said reinforcement cushion 6 generally includes and lays first floor hardcore bed 601, first floor soil grid 611, second layer hardcore bed 602, second layer GSZ 612, the 3rd layer of hardcore bed 603 from bottom to up successively.First floor soil grid 611, second layer GSZ 612 should adopt the low two-way GSZ of strain high strength, and its ultimate tensile strength is not less than 160kN/m, and elongation per unit length is not more than 10%, mesh size 80～150mm.First floor hardcore bed 601, second layer hardcore bed 602, the 3rd layer of hardcore bed 603 thickness are 0.2m.Said steel concrete binder 5 width are not less than 2 times of reinforced concrete bored pile 4 diameters, and its thickness satisfies the requirement of strength of top soil subgrade 3 and railway loading.
Some principles of the above flabbiness ground strengthened structure of the utility model high-speed railway tilted stratum that just explains through diagrams; Be not be to the utility model be confined to shown in described concrete structure and the scope of application in; So every the modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
