Abstract
The utility model discloses a supporting structure for a shallow tunnel in overpass operation, which is used for supporting a newly constructed traffic line over the existing shallow tunnel. The supporting structure comprises a supporting slab and a plurality of foundation piles, the foundation piles are arranged by both sides of the existing shallow tunnel and buried in a foundation, and the supporting slab is anchored on the top ends of the foundation piles and buried in the foundation. The span of the supporting structure for the shallow tunnel in overpass operation is small, the line elevation is low, construction is convenient, the construction cost is low, and moreover, the affection on the safe operation of the existing tunnel is little.
Description
Technical field
The utility model relate to operation in the newly-built traffic route that intersects of shallow tunnel, relate in particular to the braced structures of striding the shallow tunnel in the operation on a kind of.
Background technology
The tunnel is huge branch system on the engineering.According to the construction information investigation of a large amount of construction of tunnel, tunnel or section that the not enough Mao Dong of upper cover layer strides in the hole twice belong to shallow embedding formula tunnel.In order to make urban traffic more convenient, tend on existing shallow tunnel, build new traffic route, as, highway, railway, town road and city rail etc.
When building new traffic route above the existing shallow tunnel in operation; Safety in order to ensure the tunnel in the operation; The form of striding on the roadbed of new traffic route is commonly used promptly adopts Longspan Bridge across existing shallow tunnel, and on Longspan Bridge, builds new traffic route.Yet Longspan Bridge exists that span is big, the circuit absolute altitude is than shortcomings such as higher and cost height.
Therefore, be necessary to provide the braced structures of striding the shallow tunnel in the operation on a kind of to overcome above-mentioned defective.
The utility model content
The purpose of the utility model provides that a kind of span is little, the route absolute altitude is low, easy construction, cost is low and can guarantee the existing tunnel operation security on stride the braced structures of the shallow tunnel in the operation.
To achieve these goals; The utility model provides the braced structures of striding the shallow tunnel in the operation on a kind of; Be used for above the existing shallow tunnel of operation, supporting newly-built traffic route; It comprises gripper shoe and the stake of many foundation, and many said foundation piles are located at the both sides of existing shallow tunnel and are embedded in the ground, and said gripper shoe is anchored at the upper end of many said foundation piles and is embedded in the ground.
Preferably, the braced structures of striding the shallow tunnel in the operation on the utility model also comprises the vibration isolation plate, and said vibration isolation plate is located between said foundation pile and the said gripper shoe.Said vibration isolation plate can be used for reducing during newly-built line construction and the operation vibration for the tunnel.
Preferably, said vibration isolation plate is the foam concrete plate.
Preferably, said foundation pile comprises long sleeve, is perfused with concrete in the long sleeve.
Preferably, said foundation pile also comprises enlarged footing, and said enlarged footing is fixed on the lower end of said long sleeve.Said enlarged footing can increase the contact area of foundation pile and ground, thereby, reduce pressure to soil layer.
Preferably, said foundation pile is an end bearing pile.
Preferably, said gripper shoe is an armored concrete slab.
Preferably, the distance between the tunnel wall of the said foundation pile of vicinity of said foundation pile and existing shallow tunnel is more than or equal to 5 meters, and the distance between the tunnel wall at said gripper shoe and existing shallow tunnel top is more than or equal to 5 meters.
Compared with prior art; Can bear the load of whole or most of newly-built route owing to the gripper shoe in the braced structures of striding the shallow tunnel in the operation on the utility model; Foundation pile can be used as force transferring structure; The load of newly-built route is reached the operation tunnel below, thereby on the braced structures of the utility model, building traffic route can be to guaranteeing the safety of existing shallow tunnel.In addition, because the lower end of foundation pile is to be embedded in the ground, thereby the span of braced structures of striding the shallow tunnel in the operation on the utility model is little, easy construction, and the route absolute altitude is low and cost is low.
Through following description and combine accompanying drawing, it is more clear that the utility model will become, and these accompanying drawings are used to explain the embodiment of the utility model.
Description of drawings
Lateral view when Fig. 1 builds above existing shallow tunnel for the braced structures of striding the shallow tunnel in the operation on the utility model.
Vertical view when Fig. 2 builds above existing shallow tunnel for the braced structures of striding the shallow tunnel in the operation on the utility model.
The specific embodiment
With reference now to accompanying drawing, describe the embodiment of the utility model, the similar elements label is represented similar elements in the accompanying drawing.
Shown in Fig. 1-2, the braced structures of striding the shallow tunnel in the operation on the utility model is used for above the existing shallow tunnel of operation, supporting newly-built traffic route, and it comprises gripper shoe 10, vibration isolation plate 11 and many foundation stake 12.Many said foundation piles 12 are symmetrically set in the both sides of existing shallow tunnel 20 and are embedded in the ground.Particularly, said foundation pile 12 comprises long sleeve 121 and enlarged footing 122, and said enlarged footing 122 is fixed on the lower end of said long sleeve 121, is perfused with concrete in the said long sleeve 121.Said gripper shoe 10 is anchored at the upper end of many said foundation piles 12 and is embedded in the ground, and said vibration isolation plate 11 is located between said foundation pile 12 and the said gripper shoe 10.And the distance H between the tunnel wall at said gripper shoe 10 and existing shallow tunnel 20 tops is more than or equal to 5 meters, and the distance L between the tunnel wall of the said foundation pile 12 of vicinity of said foundation pile 12 and existing shallow tunnel 20 is more than or equal to 5 meters.
In the present embodiment, said gripper shoe 10 is an armored concrete slab, and said vibration isolation plate 11 is the foam concrete plate, and said foundation pile 12 is an end bearing pile.
Can know by technique scheme; Can bear the load of whole or most of newly-built route owing to the gripper shoe 10 in the braced structures of striding the shallow tunnel in the operation on the utility model; Foundation pile 12 can be used as force transferring structure; The load of newly-built route is reached the operation tunnel below, thereby on the braced structures of the utility model, building traffic route can be to guaranteeing the safety of existing shallow tunnel.In addition, because the lower end of foundation pile 12 is to be embedded in the ground, thereby the span of braced structures of striding the shallow tunnel in the operation on the utility model is little, easy construction, and the route absolute altitude is low and cost is low.
More than combine most preferred embodiment that the utility model is described, but the utility model is not limited to the embodiment of above announcement, and should contains various modification, equivalent combinations of carrying out according to the essence of the utility model.
