Abstract
The utility model discloses a kind of deep water anchorage shallow foundation structures, it is characterized in that, including battered leg, stiff girder under access bridge beam, access bridge pier stud, open caisson top surface, blotter, man-made island, saddle, the deep water anchorage shallow foundation structure of the utility model, make the resultant force of tension of main cable and anchorage dead load perpendicular to inclined excavation face using wedge-shaped blotter, then blotter is in the milk, so that it is safe and reliable with the contact surface of open caisson bottom plate.
Description
Technical field
The utility model relates to building field more particularly to a kind of deep water anchorage shallow foundation structures.
Background technique
For anchorage as the main force structure object of suspension bridge, main function is that tension of main cable is transmitted in ground.Cause
This, should focus on to give consideration to how the landform in conjunction with bridge location area, geologic condition, anchorage is arranged on more appropriate ground.Root
According to the difference on stress basis, anchorage is generally divided into gravity anchor and bridge anchorage.Tunnel-type anchorage be generally used for joint it is less,
At the bridge site of the exposed basement rock of rock mass mechanics better performances.The significant horizontal power of Hawser is passed in tunnel by strand, anchor pole
Concrete, then pass to by the cohesive force between concrete and rock mass in tunnel the rock mass of surrounding.And gravity anchor is generally by anchor
Body and basis composition, base form mostly use open caisson or cofferdam to enclose after water excavates and pour gravity type foundation again.Its mechanical behavior body
Now the horizontal force to act on main push-towing rope is passed on anchor block by strand and the dispersion of anchorage frame, then passes through frictional resistance by anchor block, basis
Power is transmitted on ground.Gradually rise with bridge spanning the sea in the world, suspension bridge cross over performance since its is superior, increasingly
Obtain the very big favor of engineer.
Utility model content
Problem to be solved in the utility model is to guarantee anti-pulling capacity and the life requirement of structure, the utility model master
Technical problems to be solved are to provide a kind of deep water anchorage shallow foundation structure.
Specific technical solution is accomplished by a kind of deep water anchorage shallow foundation structure, including access bridge beam, access bridge pier stud, open caisson
Battered leg, stiff girder under top surface, blotter, man-made island, open caisson bottom plate, saddle, the access bridge beam are connect with access bridge pier stud to open caisson
Top surface is further applied load, and the open caisson top surface is the basis of deep water anchorage shallow foundation structure, bearing load, the blotter grouting
With open caisson contacts baseplate, by the resultant force of main pulling force and anchorage dead load perpendicular to excavation face, it is shallow that the man-made island is built in deep water anchorage
The two sides of foundation structure, battered leg connection access bridge beam and stiff girder, build open caisson top face in, the stiff girder passes through under the saddle
It is bolted to the right end of access bridge beam, bridge load is transmitted to battered leg under saddle.
The deep water anchorage shallow foundation structure of the utility model, makes tension of main cable and anchorage dead load by wedge-shaped blotter
Resultant force perpendicular to inclined excavation face, then blotter is in the milk, so that it is safe and reliable with the contact surface of open caisson bottom plate.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model embodiment.
The label in accompanying drawing is: 1- access bridge beam, 2- access bridge pier stud, 3- open caisson top surface, 4- blotter, 5- man-made island, 6-
Battered leg, 8- stiff girder under open caisson bottom plate, 7- saddle.
Specific embodiment
The preferred technical solution of the utility model is described further with reference to the accompanying drawings and examples.
As shown in Figure 1, a kind of deep water anchorage shallow foundation structure, including access bridge beam 1, access bridge pier stud 2, open caisson top surface 3, rubble
Battered leg 7, stiff girder 8 under bed course 4, man-made island 5, open caisson bottom plate 6, saddle, the access bridge beam 1 are connect with access bridge pier stud 2 to open caisson top
Face 3 is further applied load, and the open caisson top surface 3 is the basis of deep water anchorage shallow foundation structure, bearing load, the filling of blotter 4
Slurry is contacted with open caisson bottom plate 6, and by the resultant force of main pulling force and anchorage dead load perpendicular to excavation face, the man-made island 5 is built in deep-seaanchor
The two sides of heavy stone used as an anchor shallow foundation structure, battered leg 7 connects access bridge beam 1 and stiff girder 8 under the saddle, build 3 top of open caisson top surface in, it is described plus
Strength beam 8 is bolt-connected to the right end of access bridge beam 1, and bridge load is transmitted to battered leg 7 under saddle.
Preferred embodiments of the present invention above described embodiment only expresses, the description thereof is more specific and detailed,
But it should not be understood as limiting the scope of the patent of the utility model.It should be pointed out that for the common of this field
For technical staff, without departing from the inventive concept of the premise, several deformations can also be made, improves and substitutes, these are all
Belong to the protection scope of the utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
