It is as follows using technical scheme that the present invention solves the technical problem：
A kind of high-speed railway transition segment structure of the present invention, it is characterized in that it includes：Foundation reinfored stake and cavity frame
Frame, foundation reinfored stake, which is vertically and horizontally spaced, is arranged in rows in form compound foundation in changeover portion subsoil soil, and chamber frame is set
On composite foundation；Flexible closure bag, is placed in chamber frame, and connecting tube passes through chamber frame, one end and flexible closure
Bag connection, the other end are stretched out outside chamber frame；Filling body and surface structure are protected, protection filling body placement in layers is in chamber frame
Outside both sides, surface structure is filled at the top of chamber frame.
Another technical problem to be solved by this invention is to provide the structure of one of the above high-speed railway transition segment structure
Building method, this method comprise the following steps：
1. foundation reinfored stake form compound foundation of being constructed in changeover portion subsoil soil；
2. flatten composite foundation place, the bottom and two side of chamber frame of constructing；
3. being put into flexible closure bag in chamber frame, connecting tube is tightly connected with flexible closure bag；
4. at the top of chamber frame of constructing, connecting tube outer end is stretched out outside chamber frame；
5. by injecting gases at high pressure in flexible closure bag of the connecting tube into chamber frame, rear enclosed connection is completed in aerating
Pipe；
6. the protection filling body of placement in layers chamber frame both sides；
7. fill the surface structure at the top of chamber frame.
The invention has the advantages that road-bridge transition section relative settlement can be controlled effectively, road-bridge transition section rigidity is realized
With with it is controllable；By filling gases at high pressure in chamber frame, substitute traditional graded broken stone and mix cement structures, have it is in light weight,
The features such as rigidity is big, good economy performance, and it is easy for construction, meet environmental requirement.
Brief description of the drawings
This specification includes following two width accompanying drawing：
Fig. 1 is a kind of schematic cross-sectional view of high-speed railway transition segment structure of the present invention.

Embodiment
The present invention is further described with reference to the accompanying drawings and examples：
Referring to Figures 1 and 2, a kind of high-speed railway transition segment structure of the invention includes：Foundation reinfored stake 1 and cavity
Framework 2, foundation reinfored stake 1, which is vertically and horizontally spaced, is arranged in rows in form compound foundation in changeover portion subsoil soil A, chamber frame
2 are arranged on composite foundation；Flexible closure bag 3, be placed in chamber frame 2, connecting tube 4 passes through chamber frame 2, one end with
Flexible closure bag 3 is connected, and the other end is stretched out outside chamber frame 2；Filling body 5 and surface structure 6 are protected, protection filling body 5 is layered
Fill outside the both sides of chamber frame 2, surface structure 6 is filled on the top of chamber frame 2..
The foundation reinfored stake 1 and foundation soil shared superstructure and train load being arranged in subsoil soil A, and
Subsoil soil A settling amount is controlled, solves the problems, such as the relative settlement between road and bridge.Chamber frame 2 as top surface structure and
The bearing structure of train load, the big rigidity of chamber frame 2 meet the Rigidity Matching of road-bridge transition section, and chamber frame 2 instead of
Traditional graded broken stone water mixing mud transition section structure, and with light weight, can greatly reduce to sedimentation caused by ground, so as to
Reduce the processing depth of foundation reinfored stake 1, save construction investment.By injecting gases at high pressure in flexible closure bag 3 so that chamber
Body framework 2 is rendered as entity force structure body, so as to greatly reduce the sectional dimension of chamber frame 2, saves construction investment,
It is caused to have good face to contact between the inwall of chamber frame 2 under gases at high pressure effect using flexible closure bag 3,
Make the uniform force of chamber frame 2, set connecting tube 4 that flexible closure bag 3 is carried out outside chamber frame 2 high-pressure aerated,
And constructed beneficial to gas confinement.The fixed cavity framework 2 of filling body 5 is protected, and there is good rank with non-changeover portion embankment engineering
Connect.Surface structure 6 is set on the top of chamber frame 2, percussion of the Train induced load to chamber frame 2 can be buffered,
