The length of segment is 3~6m.
A kind of high-speed rail roadbed of the invention, including rigid above-mentioned HORIZONTAL PLAID pile foundation 3 and be mounted on rigid pile foundation 3
Structure formula precast assembly segment.Rigid pile foundation 3 uses rigid pile composite foundation structure type, and two adjacent horizontal lattices are pre-
Together with the assembled segment of system is embedded in by the tenon on end face with groove, each horizontal lattice precast assembly segment is by being interspersed in
The two sides of prestressed cable anchorage in the prestressed pore passage 9, the top plate 1a form overhanging road beyond the part of bottom plate 1c
Shoulder 2, the maximum overhanging width for overhanging road shoulder can be to rail bed plate outer rim.Road shoulder is overhang as high-speed rail road shoulder structure, is had both anti-
The carrier of the accessory structures such as barrier shielding, cable trough, contact net column, the oblique ribs of setting at contact net stud.
The internal cavities of the horizontal lattice precast assembly segment can not be filled, fill or partially be filled and commonly fill out
Material, is compacted, to enhance road structure overall stability by Small Tamping Machine.
The work progress of high-speed rail roadbed of the invention is illustrated below.Horizontal lattice precast assembly in the present invention
The construction of cast-in-place and precast assembly two ways can be used in segment, and when being constructed using cast-in-place mode, top plate and inner support plate are poured and adopted
It is supported with monoblock type inner template, it is segmented to pour, when precast assembly, along line direction prefabricated subsection, integral hoisting, each segment
Length be 3~6m.
As shown in Figure 1, being poured by the segmentation of subsiding crack pitch requirements, single long length is generally not when being constructed using cast-in-place mode
Greater than 10m.In cast in situs, consolidation process is carried out to the ground within the scope of high-speed rail roadbed section first, it is compound using rigid pile
Foundation structure form forms rigid pile foundation 3；Secondly, setting up template, binding on rigid pile foundation 3 after consolidation process
Reinforcing bar, and carry out the pouring construction of the bottom plate 1c of box-structure；Later, the sidewall paneling 1b and inner support plate 1d of box-structure are bound
The reinforcing bar of middle vertical supporting plate is formed at node by design requirement and smears angle 4, plays booster action, then be arranged inner support plate 1d's
The exterior sheathing of inner template and sidewall paneling 1b, casting concrete to horizontally-supported Board position；Then, it binds horizontal in inner support plate 1d
The reinforcing bar of support plate, casting concrete to top plate 1a board bottom, the same inner template that inner support plate 1d is arranged set up overhanging road shoulder 2
Exterior sheathing, complete the pouring construction of horizontal lattice road shoulder overhanging box high-speed rail roadbed；It is supported finally, carrying out concreting
Shield, pour in concrete grade not less than C40, curing age is not less than the 100% of design strength.In addition, in box-structure
Portion can enhance the overall stability of box-structure roadbed according to the design needs using completely filling out, partly filling out or not filling out roadbed filling form；
After the completion of bedding construction, the construction of rail bed plate 5 is carried out, track plates and rail is laid with after meeting intensity requirement, overhangs road shoulder 2
Roll guard 6 is arranged in edge.
As shown in Figure 2 and Figure 3, box high-speed rail roadbed, edge are overhang using the horizontal lattice road shoulder that precast assembly mode is constructed
Roadbed line direction is segmented, and single-unit segment length is not more than 6m, and the horizontal and vertical support plate in inner support plate 1d can be by setting
Meter needs aperture, tenon and groove means for mounting coupling parts is respectively set in the joint location of two adjacent sections section, single segmental Weight control is not
More than 200t.After the completion of horizontal lattice road shoulder overhanging box high-speed rail roadbed precast segment, curing age is not less than design strength
100%, carry out on-site consolidation later.Firstly, equally carrying out consolidation process to the ground within the scope of high-speed rail roadbed section, use
Rigid pile composite foundation structure type forms rigid pile foundation 3；Secondly, lifting the horizontal lattice road shoulder overhanging high railway of box
For base pitch section to predetermined position, it is affixed that the bottom plate 1c of box-structure pours mode after using with rigid pile foundation 3；Later, continue to lift
Other segments, it is ensured that tenon and groove means for mounting coupling parts at adjacent segment joint location are mutually twisted；Then, in reserved anchor slot
Intert prestress anchorage cable in prestressed pore passage 9 in 8, the positioning lifting of the interspersed operation of prestress anchorage cable and prefabricated subsection simultaneously into
Row, it is ensured that contiguous prefabricated segment is mutually anchored build-in；Finally, repeating the above process, until horizontal lattice road shoulder overhangs box
High-speed rail roadbed is integrally formed and reaches design length.In addition, the box-structure inside after the completion of precast assembly can be according to design need
To enhance the overall stability of box-structure roadbed using not filling out, completely filling out or partly filling out roadbed filling form；Subgrade bed has been constructed
Cheng Hou carries out rail bed plate 5 and constructs, and is laid with track plates and rail after meeting intensity requirement.So far, precast splice type is completed
The on-site consolidation construction of horizontal lattice road shoulder overhanging box high-speed rail roadbed.
To sum up, horizontal lattice road shoulder of the invention overhanging box high-speed rail roadbed is compared to traditional high-speed rail made road base junction
