Description
Technical field
Grade separation underpass technical field is worn the utility model is related under, and in particular to a kind of for the half inverse of road tunnel
Make underground structure.
Background technology
Existing underground interchange or channel design form are frequently with spanning formula structure or frame culvert formula structure, spanning formula structure
It is unfavorable for big inch line gap bridge, and is generally unable to earth-covering greening, it is single etc. no that there is also leak, structure types at expansion joint
Foot；Frame culvert formula structure needs under excavation of foundation pit to bottom plate, then along construct when, bottom plate-side wall-top plate, to traffic above-ground shadow
It is long to ring the period, and municipal pipeline moves and changes that space is small, difficulty is big.
How to provide a kind of new half it is inverse make underground structure and its construction method, solve in existing construction construction joint leakage and
To the technical problem of ground traffic impact period length, becomes technical staff and need one of the project solved
Utility model content
In view of the drawbacks described above of the prior art, the technical purpose of the utility model is to provide a kind of to traffic above-ground shadow
The sound period is short, makees underground structure for the partly inverse of road tunnel.
In order to achieve the above objectives, the utility model uses following technical proposal：One kind of the utility model is used for underground
The partly inverse of road makees underground structure, including top plate, fender post, bottom plate, stand column pile, side wall, reinforced concrete upright column and shaped steel are stood
Column, the top plate are provided at both ends with end support, and centre is provided with midfoot support, and the fender post is arranged at top plate bottom
Portion, and the fender post and end support Joint, reinforced concrete upright column setting are and described in top plate bottom
Reinforced concrete upright column and midfoot support Joint, the reinforced concrete upright column are internally provided with shaped steel column；Described
Reinforced concrete upright column bottom is inserted into stand column pile.
Further, described from the position that the lower section both side ends reserved steel bar of top plate is plugged into.
Further, the shaped steel column is steel pipe column, lattice column or H profile steel column.
The beneficial effects of the utility model：
The utility model construction is simple, structure roof top can require reserved certain earthing according to the buried depth of urban pipeline
Thickness, pipeline are not passed through from structure, are easy to construct, and later stage pipeline maintenance is convenient.Structure roof can be according to traffic above-ground by stages
The demand carrying out step by step changed by stages is moved with pipeline, it is ensured that construction period traffic above-ground is not interrupted.
Description of the drawings
Fig. 1 is the underpass structure transverse face schematic diagram of the utility model；
Fig. 2 is the underpass structure A-A schematic diagrames of the utility model；
In figure, 1 top plate, the support of 101 ends, 102 midfoot supports, 3 fender posts, 4 bottom plates, 5 stand column pile, 6 side walls, 7 reinforcing bars
Concrete column, 8 shaped steel columns, 9 first time excavation faces, 10 second excavation faces.
Specific implementation mode
The technique effect of the design of the utility model, concrete structure and generation is made furtherly below with reference to attached drawing
It is bright, to be fully understood from the purpose of this utility model, feature and effect.
Embodiment 1
Shown in Fig. 1 and Fig. 2, a kind of of the utility model makees underground structure, including top plate for the partly inverse of road tunnel
1, fender post 3, bottom plate 4, stand column pile 5, side wall 6, reinforced concrete upright column 7 and shaped steel column 8,1 both ends of top plate setting
There is end to support 101, centre is provided with midfoot support 102, and the fender post 3 setting described is gone along with sb. to guard him in 1 bottom of top plate
Stake 3 supports 101 Joints, the reinforced concrete upright column 7 to be arranged in 1 bottom of top plate, and the reinforced concrete with end
Native column 7 and 102 Joint of midfoot support, the reinforced concrete upright column 7 are internally provided with shaped steel column 8；The steel
7 bottom of reinforced concrete column is inserted into stand column pile 5.
The position that the lower section both side ends reserved steel bar of the top plate 1 is plugged into.
The shaped steel column 8 is steel pipe column.
In other embodiments, the shaped steel column 8 is lattice column.
In other embodiments, the shaped steel column 8 is the combination of H profile steel column and lattice column.
Building enclosure in the utility model had not only given full play to the effect of its pattern foundation pit supporting structure in construction period, but also played it vertically
Bearing capacity undertakes top plate and its top overburden load, can restore municipal pipeline and traffic above-ground above top plate；Central post exists
Construction stage undertakes load by steel column, and service stage forms profile steel concrete column shared by steel column and concrete column.
The half inverse construction method for making underground structure for road tunnel of the utility model, includes the following steps：
(1) it is excavated to first time excavation face 9 from ground, the first time excavation face 9 is arranged under the bottom surface of top plate 1
Side；
(2) the construction fender post 3 at first time excavation face 9；
(3) construction and installation stand column pile 5 and reinforced concrete upright column 7 at excavation；
(4) formwork erection pours top plate 1 in first time excavation face 9；
(5) form removal after top plate 1 reaches design strength carries out 1 top of top plate and is laid with earthing structure 2, same period laying municipal administration
Pipeline completes pavement construction；
(6) lower section of top plate 1 from outside to inside, from top to bottom earth excavation, be excavated to second of excavation face 10, described second
The subjacent in bottom plate 4 is arranged in secondary excavation face 10；
(7) when constructing, bottom plate 4 and side wall 6 form reinforcing bar along 8 periphery formwork erection casting concrete of shaped steel column.
The construction method of the utility model is few to the influence period of traffic above-ground and municipal pipeline, and structure roof can base area
The demand carrying out step by step changed by stages is moved in face traffic with pipeline by stages, it is ensured that construction period traffic above-ground is not interrupted；Structure roof is applied
After the completion of work, top plate Construction on Ground traffic below is without influence.
The preferred embodiment of the utility model described in detail above.It should be appreciated that the ordinary skill people of this field
Member according to the present utility model can conceive without creative work makes many modifications and variations.Therefore, all this technology necks
Technical staff passes through logic analysis, reasoning or limited reality on the basis of existing technology according to the design of the utility model in domain
Available technical solution is tested, it all should be in the protection domain being defined in the patent claims.
