Abstract
A karst area light frame roadbed pile plate structure construction aims at achieving settlement and stability of high speed railway roadbed in a karst area, and solving the problems that karst foundations are not prone to be processed, detected and the like. The karst area light frame roadbed pile plate structure construction comprises foundation piles (1), joists (2), bearing bedplates (3), transverse straining beams (4) and longitudinal straining beams (5). The foundation piles (1) are arranged in a mode of being in rows with gaps in transverse direction or in a mode of being in lines with gaps in longitudinal direction. The joists (2) are transversely arranged at the tops of the foundation piles (1) in rows, and are in rigid connection with the foundation piles (1) in rows. The bearing bedplates (3) are arranged at the tops of the foundation piles (1) or the tops of the joists (2), and are in rigid connection with the foundation piles (1) or the joists (2). The transverse straining beams (4) are arranged between the foundation piles (1) in the same rows, and are in rigid connection with the foundation piles (1) in the same rows. The longitudinal straining beams (5) are arranged between the foundation piles (1) in the same lines and the same rows, and are in rigid connection with the foundation piles (1) in the same lines and the same rows.
Description
Technical field
The utility model relates to the railroad bridge structure, particularly a kind ofly is applicable to the karst intense development, solution cavity is the karst region Light-frame roadbed stake plated construction of empty solution cavity.
Background technology
China's karst features distribute extensively, area is large.Wherein maximum with the shared area of Guangxi, Guizhou and Eastern Yunnan, be one of maximum in the world karst.The southwest high-speed railway has begun a large amount of construction, and high-speed railway has all proposed Secretary to high ride, stability, the durability of circuit, and satisfy the need base base total settlement, settlement after construction and differential settlement have strict restriction.The subgrade defects such as roadbed settlement, karst collapse easily occur in the karst area soil subgrade in operation, with the serious harm traffic safety.It is limited and can't process solution cavity in the basement rock that composite foundation is processed the degree of depth; The slip casting processing method is difficult to control quality, can not guarantee effectively, and can't the Check processing effect; If the employing bridge construction, less and be positioned at the station time design difficulty comparatively when height of embankment, and cost is higher.Therefore, a kind of intensity of active demand is high, rigidity is large, stability and good endurance and the simple Novel road based structures of construction technology, and meets the requirement of environmental protection.
The utility model content
Technical problem to be solved in the utility model provides a kind of karst region Light-frame roadbed stake plated construction structure, to solve the subsidence and stabilization problem of karst area high-speed railway subgrade, avoids karst foundation to be difficult for the difficult problems such as processing and detection.
The technical scheme that its technical problem that solves the utility model adopts is as follows:
Light-frame roadbed stake plated construction in karst region of the present utility model structure is characterized in that it comprises: foundation pile, along the railway lateral separation in a row, be longitudinally spaced into row setting; Joist laterally places foundation pile in a row top and is rigidly connected with it; Bearing sheet places foundation pile or joist top and is rigidly connected with it; Straining beam is arranged at arranging between the foundation pile and being rigidly connected with it; Vertical binder is arranged between the same column row foundation pile and is rigidly connected with it.
The beneficial effects of the utility model are, have solved the subsidence and stabilization problem of karst area high-speed railway subgrade, have avoided karst foundation to be difficult for processing and the difficult problem such as detection.This roadbed combining structure has that globality is strong, good stability, sturdy and durable, is out of shape the advantages such as little, and construction technology is simple, can effectively reducing the construction costs, and meets environmental requirement, has wide popularizing application prospect.
Description of drawings
This manual comprises following two width of cloth accompanying drawings:
Fig. 1 is the cross-sectional drawing of the interval roadbed stake of the utility model karst region Light-frame plated construction structure;
Fig. 2 is the skiagraph of the interval roadbed stake of the utility model karst region Light-frame plated construction structure.
The title of member shown in the figure and corresponding mark: foundation pile 1, joist 2, bearing sheet 3, straining beam 4, vertical binder 5, roadbed filling soil 6 is empty solution cavity in the above-ground route 7, dotted line.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
See figures.1.and.2, Light-frame roadbed stake plated construction in karst region of the present utility model structure, it comprises: foundation pile 1, along the railway lateral separation in a row, be longitudinally spaced into row setting; Joist 2 laterally places foundation pile in a row 1 top and is rigidly connected with it; Bearing sheet 3 places foundation pile 1 or joist 2 tops and is rigidly connected with it; Straining beam 4 is arranged at arranging between the foundation pile 1 and being rigidly connected with it; Vertical binder 5 is arranged between the same column row foundation pile 1 and is rigidly connected with it.The utility model bears the vertical gravity that roadbed filling soil 6, train and track structure produce by foundation pile 1, form the space frame system by foundation pile 1, straining beam 4, vertical binder 5 and bear train horizontal loading and temperature load, avoided the impact of Roadbed Soil pressure on karst foundation, straining beam 4, vertical binder 5 are rigidly connected with foundation pile 1, increased the horizontal and vertical rigidity of foundation pile, can effectively alleviate karst foundation and subside on the impact of foundation pile stability.This structure has solved the subsidence and stabilization problem of karst area high-speed railway subgrade, has avoided karst foundation to be difficult for the difficult problems such as processing and detection.This roadbed combining structure has that globality is strong, good stability, sturdy and durable, is out of shape the advantages such as little, and construction technology is simple, can effectively reducing the construction costs, and meets environmental requirement, has wide popularizing application prospect.
Described foundation pile 1, joist 2, bearing sheet 3, straining beam 4, vertical binder 5 all adopt steel concrete to build, and foundation pile 1 vertical main reinforcement need stretch in joist 2 or the bearing sheet 3 and be attached thereto into an integral body.
Described bearing sheet 3 per 3 ~ 5 strides one, at joist 2 middle parts one place, shrinkage joint is set between adjacent, and the filling of pitch plank is adopted at the shrinkage joint.On the bearing sheet 3 AT STATION switch area to establish length be that the roadbed filling of 1～3m bankets 6, interval roadbed can not established roadbed filling soil 6
See figures.1.and.2, described straining beam 4, vertical binder 5 are arranged in the place, ground.When longitudinal rigidity is not enough, can at vertical binder more than 5, between same column row foundation pile 1, be provided with the second row straining beam that is rigidly connected with it.
Some principles of the above the interval roadbed stake of the utility model karst region Light-frame plated construction structure that just explains through diagrams, be not be the utility model to be confined to shown in and in described concrete structure and the scope of application, therefore every corresponding modify that might be utilized and equivalent all belong to the claim that the utility model is applied for.
