Abstract
The utility model discloses an overhead-type roadbed pile board structure for a high speed railway. According to the overhead-type roadbed pile board structure for the high speed railway, the problem that post construction settlement and uneven settlement of unfavorable geology or deep soil layer sections after railway roadbeds are constructed on the unfavorable geology or the deep soil layer sections is controlled, and the overhead-type roadbed pile board structure for the high speed railway can be organically connected with after-station associated works afterwards. The overhead-type roadbed pile board structure for the high speed railway comprises a roadbed (1), cast-in-situ bored piles (2), a joist (3), a bearing sheet (4), frange plates (5) and cable troughs (7), wherein the roadbed (1) is filled on a foundation bedrock soil body, the cast-in-situ bored piles (2) are longitudinally arranged along a route at intervals and two rows of the cast-in-situ bored piles (2) are horizontally arranged along the roadbed, the lower portions of the cast-in-situ bored piles (2) penetrate through a unfavorable rock-soil body and are arranged on the steady foundation rock-soil body, the joist (3) is horizontally arranged on the top portions of the cast-in-situ bored piles (2) and is connected with the cast-in-situ bored piles (2) in a rigid mode, the bearing sheet (4) is arranged on the top portion of the joist (3), the frange plates (5) are arranged on the outer side of the bearing sheet, contact net pillar reserved holes (6) are formed in the frange plates (5), and the cable troughs (7) are fixedly formed in the frange plates (5).
Description
Technical field
The utility model relates to a kind of railway bed structure, particularly a kind of high-speed railway overhead type roadbed stake plated construction.
Background technology
In unfavorable geology and Deep Soil Layers ground, usually adopt roadbed stake plated construction to pass through in the high speed railway construction, when adopting shallow embedding formula roadbed stake plated construction, Roadbed Soil between bearing sheet and track plates supporting bed easily produces bad disease under the Train induced load long term; When adopting deep embeded type roadbed stake its bearing sheet of plated construction and pile foundation need bear that banket in top and the track train load, it is stressed larger, and cost of investment is higher; Tradition overhead type roadbed stake plated construction generally only is arranged in track plates supporting bed width range bottom, the both sides curb adopts roadbed filling to fill usually, the differential settlement that cable channel and bearing sheet often occur, the result usually causes cable channel to damage and road bed ponding infiltrates the roadbed filling body.Therefore, a kind of settlement Control of active demand effective, can and meet the High Speed Railway Subgrade of environmental requirement with correlation engineering organic linking, reduced investment behind the station, simple in structure, easy construction.
The utility model content
Technical problem to be solved in the utility model provides a kind of high-speed railway overhead type roadbed stake plated construction, can effectively control unfavorable geology or Deep Soil Layers paragraph construct a railway post-construction settlement of subgrade and differential settlement, and can with correlation engineering organic linking behind the station.
The technical scheme that its technical problem that solves the utility model adopts is as follows:
High-speed railway overhead type roadbed stake plated construction of the present utility model, comprise the roadbed that fills on the ground Rock And Soil, it is characterized in that it also comprises: bored pile, arrange and arrange along roadbed horizontally set two along circuit longitudinal separation, its underpart is passed bad Rock And Soil and is placed on the firm ground Rock And Soil; Joist is horizontally set at the bored pile top and is rigidly connected with it; Bearing sheet is arranged at the joist top; Frange plate is arranged at the bearing sheet outside, is provided with the catenary mast preformed hole on it; Cable channel is fixedly installed on the frange plate.
The beneficial effects of the utility model are, can effectively control unfavorable geology or Deep Soil Layers paragraph construct a railway post-construction settlement of subgrade and differential settlement, and can with the station after the correlation engineering organic linking, have the characteristics such as structural integrity is good, simple in structure, easy construction, and meet environmental requirement, have wide popularizing application prospect.
Description of drawings
This manual comprises following two width of cloth accompanying drawings:
Fig. 1 is the schematic cross-sectional view of the utility model high-speed railway overhead type roadbed stake plated construction;
Fig. 2 is the floor map of the utility model high-speed railway overhead type roadbed stake plated construction.
Member shown in the figure, toponym and corresponding mark: roadbed 1, bored pile 2, joist 3, bearing sheet 4, frange plate 5, catenary mast preformed hole 6, cable channel 7.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
See figures.1.and.2, high-speed railway overhead type roadbed stake plated construction of the present utility model comprises: fill the roadbed 1 on the ground Rock And Soil; Bored pile 2 arranges and arranges along roadbed horizontally set two along circuit longitudinal separation, and its underpart is passed bad Rock And Soil and placed on the firm ground Rock And Soil; Joist 3 is horizontally set at bored pile 2 tops and is rigidly connected with it; Bearing sheet 4 is arranged at joist 3 tops; Frange plate 5 is arranged at the bearing sheet outside, is provided with catenary mast preformed hole 6 on it; Cable channel 7 is fixedly installed on the frange plate 5.Bearing sheet 4 supports upper track and train load, and joist 3 passes to bored pile 2 with top bearing sheet 4, upper track and train load, bears joist 3, bearing sheet 4, upper track and train load by bored pile 2.Frange plate 5 connects into integral body with bearing sheet 4, and cable channel 7 is arranged thereon, can avoid traditional cable groove and bearing sheet to disconnect and differential settlement occur, avoids bearing sheet 4 and road surface, 7 slits of wiring duct water to infiltrate.This structure efficiently solves the high-speed railway subgrade sedimentation and guarantees on the roadbed that cable channel is stable and avoid the road surface to ooze the problems such as roadbed under water, have the characteristics such as structural integrity is good, simple in structure, easy construction, and meet environmental requirement, have wide popularizing application prospect.
See figures.1.and.2, described bored pile 2 is with respect to roadbed 1 center line lateral symmetry layout, and the degree of depth satisfies the high-speed railway settlement request, and its longitudinal pitch is generally 6～10m, and diameter is generally 0.8～1.2m.Described bearing sheet 4 adopts framing type, is arranged symmetrically with respect to roadbed 1 center line.Described frange plate 5 adopts reinforced concrete whole-casting with bearing sheet 4, and thickness is generally 0.4～0.5m.
Some principles of the above the utility model high-speed railway overhead type roadbed stake plated construction 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.
