Abstract
A buttress type U-shaped groove structure is characterized by simple and clear structure stress, safe construction, strong wholeness and good stability. The buttress type U-shaped groove structure comprises a left side reinforced concrete side wall (11), a right side reinforced concrete side wall (12), a reinforced concrete base plate (20) and reinforced concrete rib plates (30), wherein the left side reinforced concrete side wall (11) and the right side reinforced concrete side wall (12) are arranged below two sides of a roadbed in a left and right symmetrical mode, the reinforced concrete base plate (20) is arranged below the roadbed and fixedly connected with the lower ends of the left side reinforced concrete side wall (11) and the right side reinforced concrete side wall (12), the reinforced concrete rib plates (30) are arranged between the left side reinforced concrete side wall (11) and the reinforced concrete base plate (20) and between the right side reinforced concrete side wall (12) and the reinforced concrete base plate (20) at intervals along a route direction in a fixedly connecting mode.
Description
Technical field
The utility model relates to railway, highway and town road roadbed, particularly the U-shaped groove structure of a kind of buttress type.
Background technology
At railway, in the construction process of highway and town road, the situation of wearing existing building under needing is very many, connecing the lower framework of wearing or the part at two, tunnel, if groundwater table is higher and the water permeability on stratum when better, then do not possess the condition of forever putting the slope, it is good selection that closed U-shaped groove is set, if but the cantilever of U-shaped groove is higher, when perhaps groundwater table is higher, common U-shaped trough rim wall is very large, and uplift pile need to be set solve the anti-floating problem, and resistance to plucking pile construction and be difficult to guarantee with the quality of connection of U-shaped trough floor, and can destroy the whole structure of the outer packaging waterproof layer of structure.Therefore the new structure structure that solves problems has very large demand.
The utility model content
Technical problem to be solved in the utility model provides the U-shaped groove structure of a kind of buttress type, has that structure stress is simple clear and definite, construction safety, globality are strong, the characteristics of good stability.
The technical scheme that its technical problem that solves the utility model adopts is as follows:
The U-shaped groove structure of buttress type of the present utility model is characterized in that it comprises: left side steel concrete abutment wall and right side steel concrete abutment wall, be arranged under the roadbed both sides, and be symmetrical set usefulness; Reinforced concrete floor is arranged at below the road bed, and is fixed with the lower end of left side steel concrete abutment wall, right side steel concrete abutment wall; The steel concrete floor is arranged between left side steel concrete abutment wall and reinforced concrete floor, right side steel concrete abutment wall and the reinforced concrete floor and fixed with it, arranges along circuit direction interval.
The beneficial effects of the utility model are, the oversize problem of abutment wall when both having solved common U-shaped groove high and groundwater table is higher at cantilever, avoid again arranging uplift pile, this structure stress is simply clear and definite, and safety is higher, and globality is strong, good stability, and construction safety, have wide popularizing application prospect.
Description of drawings
This manual comprises following three width of cloth accompanying drawings:
Fig. 1 is the cross-sectional drawing of the U-shaped groove structure of the utility model buttress type;
Fig. 2 is the front view of the U-shaped groove structure of the utility model buttress type;
Fig. 3 is the plan view of the U-shaped groove structure of the utility model buttress type;
Member shown in the figure, division name and corresponding mark: left side steel concrete abutment wall 11, right side steel concrete abutment wall 12, reinforced concrete floor 20, steel concrete floor 30.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
With reference to Fig. 1, Fig. 2 and Fig. 3, the U-shaped groove structure of buttress type of the present utility model comprises: left side steel concrete abutment wall 11 and right side steel concrete abutment wall 12, be arranged under the roadbed both sides, and be symmetrical set usefulness, play closing slope and waterproof action; Reinforced concrete floor 20 is arranged at below the road bed, and is fixed with the lower end of left side steel concrete abutment wall 11, right side steel concrete abutment wall 12, rises and bears vertical load and waterproof action; Steel concrete floor 3, be arranged between left side steel concrete abutment wall 11 and reinforced concrete floor 20, right side steel concrete abutment wall 12 and the reinforced concrete floor 20 and fixed with it, arrange along circuit direction interval, play the effect of sharing the bending and shearing on the steel concrete abutment wall 1.The oversize problem of abutment wall when this structure had both solved common U-shaped groove high and groundwater table is higher at cantilever, avoid again arranging uplift pile, this structure stress is simply clear and definite, and safety is higher, be applicable to that groundwater table is higher, connect railway, highway and the town road roadbed at framework or two, tunnel when wearing under the cutting location, particularly circuit of stratum good water permeability.
With reference to Fig. 3, the longitudinal pitch of described steel concrete floor 30 adjacent both sides of the chest is 3～6m, adopts graded broken stone water mixing mud to fill coefficient of compaction K 〉=0.8 between the adjacent both sides of the chest.With reference to Fig. 2, described reinforced concrete floor 20 is 1～3m with respect to left side steel concrete abutment wall 11, the right side steel concrete abutment wall 12 outwardly directed partial-lengths of encorbelmenting.
Some principles of the above U-shaped groove structure of the utility model buttress type 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.
