Technical field
The present invention relates to railway, highway subgrade discharge structure, particularly a kind of mountain area groove cutting subgrade drainage structure.
Background technology
China's alpine terrain groove in length and breadth; Build railway, highway engineering owing to receive the requirement of landform or special engineering, have some groove cutting subgrade constructions, groove cutting subgrade stability and draining are very difficult for this reason; Particularly high-speed railway has clearly proposed roadbed sky ditch-water and should not enter in the subgrade drainage system; Guaranteeing railway bed safety, when groove water must from railway bed through the time, then must take a kind of draining fast effectively, can guarantee the stable and safety of railway bed; And the simple cutting subgrade drainage of construction technology structure, and meet environmental protection requirement.
Summary of the invention
Technical problem to be solved by this invention provides a kind of mountain area groove cutting subgrade drainage structure, and the cutting good stability has good drainage effect, and simple in structure.
The technical solution adopted for the present invention to solve the technical problems is following:
Groove cutting subgrade drainage structure in mountain area of the present invention is characterized in that it comprises: steel concrete anchoring stake, be arranged at groove section excavation side slope toe, and road along the line longitudinal separation is provided with; The steel concrete breast boards is arranged at anchor pile backer side; Concrete hangs ditch, is arranged at the steel concrete breast boards outside, with the groove center-aligned; Mortar flag stone is paved, and is arranged at excavation cutting moat item, paves to both sides in the ditch groove center; Mortar flag stone hangs the ditch basis, is arranged at the steel concrete breast boards outside and hangs the ditch bottom; Sedimentation basin is arranged on the groove cutting lateral sulcus platform, and hangs ditch outlet and is connected; Cross the water culvert, be arranged at groove cutting bedding bottom, backer's side is communicated with sedimentation basin, and outlet is communicated with natural groove.
Said cutting bedding is the embankment cutting, depth of fill >=0.5m.
The invention has the beneficial effects as follows to have good drainage effect, and groove cutting resistance to overturning is good; Construction technology is simple, can effectively reduce the engineering construction cost, and compliance with environmental protection requirements, therefore 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 groove cutting subgrade drainage structure in mountain area of the present invention;
Fig. 2 is the plan view of groove cutting subgrade drainage structure in mountain area of the present invention.
Component shown in the figure, toponym and pairing marker number: mortar flag stone paves 1, concrete hangs ditch 2, mortar flag stone hangs ditch basis 3, steel concrete anchoring stake 4, steel concrete breast boards 5, sedimentation basin 6, cross water culvert 7, groove cutting bedding 8, connect ditch 9.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
See figures.1.and.2, groove cutting subgrade drainage structure in mountain area of the present invention comprises: steel concrete anchoring stake 4, be arranged at groove section excavation side slope toe, and road along the line longitudinal separation is provided with; Steel concrete breast boards 5 is arranged at anchor pile 4 backer's sides; Concrete hangs ditch 2, is arranged at steel concrete breast boards 5 outsides, with the groove center-aligned; Mortar flag stone paves 1, is arranged at excavation cutting moat top, paves to both sides in the ditch groove center; Mortar flag stone hangs ditch basis 3, is arranged at steel concrete breast boards 5 outsides and hangs ditch 2 bottoms; Sedimentation basin 6 is arranged on the cutting lateral sulcus platform, and hangs ditch 2 outlet and is connected; Cross water culvert 7, be arranged at groove cutting bedding 8 bottoms, backer's side is communicated with sedimentation basin 6, and outlet is communicated with natural groove.
The present invention makes full use of 4 pairs of groove cuttings of steel concrete anchoring stake and props up retaining reinforcing assurance stable slope property; Utilize the groove soil body between the 5 firm steel concrete anchoring stakes 4 of steel concrete breast boards; Utilize mortar flag stone to pave 1 and avoid the steel concrete breast boards 5 back groove regoliths to empty and avoid a large amount of groove water to infiltrate the soil body thereafter, it is stable that the reduction soil strength influences the groove cutting; Utilize concrete to hang ditch 2 along connecing groove water and reducing the groove water potential energy; Utilize sedimentation basin 6 to reduce groove water slug ability, silt particle in the deposition water reduces downstream exhalant canal alluvial, guarantees that draining is unimpeded fast; Utilized water culvert 7 to get rid of the railway bed influence basin to groove water in the sedimentation basin; Groove cutting bedding 8 is made embankment formula cutting, and its depth of fill >=0.5m guarantees that roadbed has the safe enough height.This discharge structure structure has that the cutting resistance to overturning is good, drainage effect is good, and construction technology is simple, can effectively reducing the construction costs, and compliance with environmental protection requirements, have wide popularizing application prospect.
With reference to Fig. 1, said concrete hangs ditch 2 bottoms of trench and is step-like, is beneficial to the drop energy dissipating, and shoulder height is generally about 0.2m.With reference to Fig. 2, said mortar flag stone paves 1, paves length 10～20m from steel concrete breast boards 5 to groove top, pave width from the ditch groove center to each 3～5m of both sides.Said sedimentation basin 6 adopts the C30 concrete pouring, and the degree of depth is 1.0～2.0m, and downline road direction length is consistent with groove width, and vertical rail track direction width is generally 10～20m.See figures.1.and.2, said water culvert 7 water inlets of crossing are communicated with sedimentation basin 6 through connecting ditch 9, and delivery port and natural groove are good along connecing, and its physical dimension guarantees to satisfy the requirement of groove drain discharge.When the excavation height hour, said water culvert 7 delivery ports of crossing can be taked to dig the open drain mode and discharge culvert water, when the excavation height is higher, can adopt drain cavern is set discharges culvert water fast, its draining longitudinal gradient >=4%.
Some principles of the above groove cutting subgrade drainage structure in mountain area of the present invention that just explains through diagrams; Be not be to the present invention be confined to shown in described concrete structure and the scope of application in; So every the modify and equivalent that might be utilized, the claim that all belongs to the present invention and applied for.
