Abstract
A tray type U-shaped reinforced subgrade structure comprises a retaining wall, two cantilever plates, a plurality of lacing bars and filler, wherein the retaining wall has a structure with a U-shaped horizontal section and arranged along the laying direction of a rail; the two cantilever plates are formed by extending horizontally outwards from the upper ends of two side surfaces of the retaining wall; the plurality of lacing bars are horizontally connected between the two side surfaces of the retaining wall; and the filler is filled in a space in the retaining wall. For the tray type U-shaped reinforced subgrade structure, as the retaining wall has a hollow structure, the load on a body can be reduced; and as the area of a basement is small, the reinforcing area and the occupied floor are small, so that the cost for reinforcement and processing can be obviously reduced, the land resources can be saved, and the environment protection and energy conservation can be facilitated. In addition, as the retaining wall and cantilever plates have reinforced concrete structures, the excellent integrity can be realized, therefore, the subside deformation of a foundation after engineering can be controlled, and the foundation can be free of differential settlement, and the structure is particularly suitable for areas with land resources being lacked or soft.
Description
Technical field
The utility model belongs to railway art, particularly relates to a kind of pellet type U-shaped reinforcement road structure.
Background technology
Along with the fast development of high-speed railway, in order to ensure train high speed, safety and even running, road structure should have enough intensity, stability and durability.Wherein non-fragment orbit Line for Passenger Transportation and high-speed railway lay special stress on roadbed settlement after construction Deformation Control, therefore the ground of natural soil property generally all can not satisfy high-level sedimentation and deformation control requirement, the weak soil of especially deep compression layer and mollisol roadbed are so must carry out consolidation process to the ground of railway laying place before placing an iron railway.Road structure form commonly used at present mainly contains trapezoidal road structure, upright road structure etc.Fig. 1 is the trapezoidal road structure transverse sectional view of prior art.As shown in Figure 1, this trapezoidal road structure is that a kind of lateral cross section is trapezoidal fill subgrade structure.Though this trapezoidal road structure can be guaranteed train high speed, safety and even running, but shortcoming is to need gamut to reinforce, and floor space is big, so engineering quantity and construction investment are big, and roadbed body globality is poor, so be difficult to control preferably differential settlement.Upright road structure mainly is divided into two kinds of upright shelves road structure and U-shaped road structures.Fig. 2 is a upright shelves road structure transverse sectional view of prior art.As shown in Figure 2, this upright shelves road structure falls T-shaped retaining wall 1 by the two sides that is arranged on the roadbed both sides and the filler 2 that is filled between the two sides retaining wall 1 is formed.Fig. 3 is the U-shaped road structure transverse sectional view of prior art.As shown in Figure 3, this U-shaped road structure filler 4 that is the retaining wall 3 of U font by lateral cross section and is filled in retaining wall 3 inside is formed.Though above-mentioned two kinds of upright road structures can be guaranteed train high speed, safety and even running, reinforcing scope and floor space are little, and shortcoming is that the globality and the control differential settlement aspect of roadbed body is relatively poor, and construction investment is still higher.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of good whole that has, and can prevent uneven settlement of foundation effectively, and the lower pellet type U-shaped reinforcement road structure of construction costs.
In order to achieve the above object, the pellet type U-shaped reinforcement road structure that provides of the utility model comprises retaining wall, two suspended wall plates, many lacing wires and filler; Wherein retaining wall is the structure of U font for the lateral cross section of laying the direction setting along railway; Two suspended wall plates are that upper end, the two sides level from retaining wall stretches out and forms; Many lacing wire levels are connected between the two sides of retaining wall; Filler then fills in the inner space of retaining wall.
The many lacing wires that described level is connected between the retaining wall two sides are provided with in the modes of arranging up and down more.
Described retaining wall and two suspended wall plates are integrally formed, and are reinforced concrete structure.
The span of described retaining wall equals the width of load.
Retaining wall on the pellet type U-shaped reinforcement road structure that the utility model provides is a hollow-core construction, therefore can reduce the load of body, and area of base is little, so reinforcing scope and floor space are little, thereby can obviously reduce the consolidation process expense, and save land resources, help environmental protection and energy saving.In addition,, therefore have good whole,, prevent that differential settlement from appearring in ground, be specially adapted to Tu Yuan and lack or soft area so help controlling the sedimentation and deformation of worker's groundwork because retaining wall and suspended wall plate are reinforced concrete structure.

The pellet type U-shaped reinforcement road structure transverse sectional view that Fig. 4 provides for the utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the pellet type U-shaped reinforcement road structure that the utility model provides is elaborated.
As shown in Figure 4, the pellet type U-shaped reinforcement road structure that provides of the utility model comprises retaining wall 5, two suspended wall plates 6, many lacing wires 7 and filler 8; Wherein retaining wall 5 is the structure of U font for the lateral cross section of laying the direction setting along railway; Two suspended wall plates 6 are that upper end, the two sides level from retaining wall 5 stretches out and forms; Many lacing wire 7 levels are connected between the two sides of retaining wall 5; 8 of fillers fill in the inner space of retaining wall 5.
The many lacing wires 7 that described level is connected between retaining wall 5 two sides are provided with in the modes of arranging up and down more.
Described retaining wall 5 and two suspended wall plates 6 are integrally formed, and are reinforced concrete structure.
The span of described retaining wall 5 equals the width of load.
The pellet type U-shaped reinforcement road structure work progress that now the utility model is provided describes: the retaining wall 5 on this pellet type U-shaped road structure and two suspended wall plates 6 can adopt batch production, standardization to make, and reservation lacing hole, length can rationally determine according to traffic condition, is transported to the job site again after prefabricated to assemble; Also can adopt the mode of on-the-spot formwork erection cast to make retaining wall 5 and two suspended wall plates 6, treat concrete intensity reach design strength 80% after, can be in retaining wall 5 layered backfill.When the soil layer height reaches next row's lacing wire 7 positions, next row's lacing wire 7 is installed, continue then to banket, be positioned at the lacing wire 7 of next row's lacing wire 7 top more successively, so repeatedly, until the upper end open place that reaches retaining wall 5.
