Description
Technical field
The utility model relates to High Speed Railway Subgrade technical field, in particular to a kind of high-speed railway cast-in-situ bored pile
Frame-type road structure.
Background technique
Currently, building high-speed rail since qualified filler lacks in region of no relief, far fortune is needed to handle, and foundation soil is generally relatively deep
It is thick, soft, basement process need to be carried out, roadbed filling and basement process expense are huge, and every kilometer of section roadbed is comprehensive at 6 meters of raising
It closes cost and is as high as 5000~60,000,000 yuan, without economic advantages compared with bridge.Therefore, in region of no relief when raising is more than 6 meters
After mostly use " interface height " to handle, route " bridge tunnel ratio " is high, and Railway Investment increases more.
In the case, how in region of no relief to design a kind of novel " roadbed " structural shape, make it to account for less arable land,
Amount of filler and foundation treatment engineering amount are reduced, to reduce every kilometer of cost, is had compared with Traditional foundations or bridge more preferable
Economy, be current main problem urgently to be solved.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of high-speed railway cast-in-situ bored pile frame-type roadbed knots
Structure reduces high speed railway construction investment to effectively reduce cultivated land occupancy amount, amount of filler and foundation treatment engineering amount.
It is as follows that the utility model solves the technical solution that above-mentioned technical problem is taken:
A kind of high-speed railway cast-in-situ bored pile frame-type road structure of the utility model, it is characterized in that: including by drilling
The frame construct that bored concrete pile, crossbeam and joist are constituted, and it is set to longitudinally extending at the top of the frame construct along route
Groove profile straddle；The cast-in-situ bored pile route is horizontally arranged at interval, and longitudinal at two column settings along route, and its underpart is located at ground
In base；The crossbeam is located at foundation surface or more, two cast-in-situ bored piles consolidation at both ends and route transverse direction；The joist setting
In two cast-in-situ bored piles of route transverse direction stake top and consolidate therewith, groove profile straddle is set on joist top surface.
The utility model has the beneficial effects that providing a kind of novel subgrade structure, arable land can be effectively reduced
Occupancy, amount of filler and foundation treatment engineering amount, to reduce high speed railway construction investment；Structure is simple, easy for construction, applies
Work is high-efficient, has broad prospect of application in Plain or the area for lacking filler.
Detailed description of the invention
This specification includes following four width attached drawing:
Fig. 1 is the skiagraph of the utility model high-speed railway cast-in-situ bored pile frame-type road structure；
Fig. 2 is the cross-sectional view of the utility model high-speed railway cast-in-situ bored pile frame-type road structure；

Specific embodiment
The utility model is further illustrated below by specific embodiment and in conjunction with attached drawing.
Referring to Figures 1 and 2, a kind of high-speed railway cast-in-situ bored pile frame-type road structure of the utility model, including by
The frame construct that cast-in-situ bored pile 1, crossbeam 2 and joist 3 are constituted, and be set to vertical along route at the top of the frame construct
To the groove profile straddle 4 of extension.1 route of cast-in-situ bored pile is horizontally arranged at interval, and is arranged along longitudinal arrange at two of route,
Lower part is located in ground D.The crossbeam 2 is located at the surface ground D or more, and both ends and two cast-in-situ bored piles 1 of route transverse direction are solid
Knot, plays lifting frame posture road structure lateral stiffness.The joist 3 is set to two cast-in-situ bored piles 1 of route transverse direction
Stake top and consolidate therewith, play a part of transmit upper load.Groove profile straddle 4 is set on 3 top surface of joist.Belong to a kind of novel
" roadbed " structural shape, cultivated land occupancy amount, amount of filler and foundation treatment engineering amount can be effectively reduced, thus reduce high speed
Investment of railway construction；
Referring to Fig.1, the cast-in-situ bored pile 1, joist 3 and groove profile straddle 4 are longitudinally equally spaced along route.The drilling
1 stake top of bored concrete pile anchors into 3 bottom of joist and consolidation is integrated, and 2 both ends of crossbeam anchor into cast-in-situ bored pile 1 and consolidation is one
Body.
Referring to Fig. 3, the both ends of the joist 3 have the positive stop lug boss 3a to raise upward, the positive stop lug boss 3a constraint at both ends
4 lateral displacement of groove profile straddle.
Referring to Fig. 2 and Fig. 4, the two sides of the groove profile straddle 4 have the earth-retaining abutment wall 4b to raise upward, and filling body 5 fills
It is intracavitary in earth-retaining abutment wall 4b inner sidewall and groove profile more than 4 top surface of groove profile straddle, have energy dissipating and reduces substructure dynamic response
Effect.Track structure 8 is set on filling body 5, cable trough 6 is set on the top surface earth-retaining abutment wall 4b.On the top surface of the groove profile straddle 4
