Description
Technical field
This utility model belongs to civil structural engineering, railway traffic engineering technical field, is specifically related to a kind of contact net and stands
Column foundation and railway roadbed track plates build structure jointly.
Background technology
Modern tram typically uses ground entirety ballastless track bed, the pattern that contact net is powered.Overall ballastless track bed by
Armoured concrete slab, surface layer of subgrade bed cement stabilized macadam (the steady layer of water), roadbed composition under track, and contact net column typically uses
Isolated footing, owing to contact net column needs to bear bigger pulling force and moment of flexure, the size of its isolated footing needs and buried depth are relatively
Greatly, the steady layer of water and the roadbed of track foundation can be destroyed, be likely to result in track differential settlement, thus give the safe operation band of train
Carry out certain potential safety hazard；Net-fault column uses isolated footing construction relatively difficult simultaneously, and cost is the highest.
Summary of the invention
The purpose of this utility model is contemplated to solve the deficiency that above-mentioned background technology exists, it is provided that a kind of easy construction is fast
Contact net upright post basic and railway roadbed track plates prompt, low cost build structure jointly.
The technical solution adopted in the utility model is: a kind of contact net upright post basic builds structure jointly with railway roadbed track plates, bag
Include roadbed, surface layer of subgrade bed and the concrete railway board from bottom to top set gradually, in the middle part of described concrete railway board, be provided with contact
Net upright post basic, described net-fault upright post basic includes contact net column and is positioned at the concrete column of contact net column bottom, institute
State concrete column connection integrated with concrete railway board.Connect integrated with concrete railway board of concrete column can guarantee that
When contact net column stress is bigger, concrete railway board can share part stress, improves the reliability of contact net column；The most not
Need to excavate completed track bed, convenient and quick construction.
Further, described concrete column includes concrete block and pours in the sill anchor within concrete block, institute
State concrete block connection integrated with concrete railway board.
Further, described concrete block top and bottom are respectively equipped with the first pre-embedded steel slab and the second pre-embedded steel slab, institute
State sill anchor top and bottom to fix with the first pre-embedded steel slab and the second pre-embedded steel slab respectively and be connected, at the bottom of described contact net column
Portion is fixing with the first pre-embedded steel slab to be connected, the steel bar stress of described second pre-embedded steel slab laminating concrete railway board interior bottom portion.
Further, the height at described concrete block top is higher than the height at concrete railway board top.Concrete block
Highly higher than the height of concrete railway board, it is possible to strengthen sill anchor anchoring strength, to improve structure tension performance, make contact
Net column stress is preferably transferred to track plates.
Further, described contact net column lower end sidewall is vertically provided with multiple ribbed stiffener.
This utility model contact net upright post basic is integrated with concrete railway board to be connected, and reasonable stress, easy construction is fast
Speed, decreases roadbed under destruction ballast bed of track, can save a large amount of construction costs and duration.

Detailed description of the invention
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings, it is simple to is well understood to
This utility model, but they do not constitute restriction to this utility model.
As shown in Figure 1 and Figure 2, this utility model includes roadbed 1, surface layer of subgrade bed 2 and the concrete from bottom to top set gradually
Track plates 3, is provided with contact net upright post basic 5 in the middle part of described concrete railway board 3, described net-fault upright post basic 5 includes contact net
Column 6 and the concrete column 7 being positioned at contact net column bottom, described concrete column 7 is integrated with concrete railway board 3 even
Connecing, contact net stands and is vertically provided with multiple ribbed stiffener 12 on 6 lower end sidewalls.
In such scheme, concrete column 7 includes concrete block 8 and pours in the sill anchor 9 within concrete block, institute
State concrete block 8 connection integrated with concrete railway board 3.Concrete block 8 top and bottom are respectively equipped with the first pre-embedded steel slab
10 and second pre-embedded steel slab 11, described sill anchor 9 top and bottom respectively with the first pre-embedded steel slab 10 and the second pre-embedded steel slab
11 fixing connections, fix with the first pre-embedded steel slab 10 bottom described contact net column 6 and are connected, and described second pre-embedded steel slab 11 is fitted
The steel bar stress 4 of concrete railway board 3 interior bottom portion is secured to connect.The height at described concrete block 8 top is higher than coagulation
The height at soil track plates 3 top.
This utility model contact net upright post basic 5 is integrated with concrete railway board 3, primary concreting, it is not necessary to
Excavation foundation again, does not destroy track bed and the steady layer of water, convenient and quick construction, saves man-hour, and construction costs is low.And contact net
Column stress can be transferred to track plates by sill anchor, and reasonable stress is reliable, meets contact net force request.
Work progress of the present utility model is:
1), before foundation construction, subgrade strengthening should be completed according to the selected subgrade strengthening scheme of place geologic prospect report.
2), after subgrade strengthening is checked and accepted after testing and met design requirement, (water is steady for construction surface layer of subgrade bed cement stabilized macadam
