Abstract
A small-medium span suspension bridge anchorage structure under weak geological conditions can effectively avoid construction risk and reduce construction difficulty and construction costs, and comprises an anchorage (10). A pile group foundation fixedly integrated with the anchorage is arranged under the anchorage (10) and formed by foundation piles (30) and bearing platforms (20). The foundation piles (30) are longitudinally and transversely embedded in a weak foundation soil body at intervals, the bearing platforms (20) are fixedly connected onto the pile tops of the foundation piles (30), and the bottom surfaces of the bearing platforms (20) are contacted with the weak foundation soil body.
Description
Technical field
The utility model relates to civil construction project, is specially adapted to the anchorage structure of medium and small span suspension bridge under the weak geological conditions.
Background technology
Earth anchored suspension bridge in the bridge engineering need be passed to ground through anchorage with the huge pulling force of main push-towing rope.Under the geological conditions good conditions, adopt the tunnel-type anchorage power transmission usually, under weak geological conditions, adopt the gravity anchor power transmission usually.The tradition gravity anchor mainly relies on the uplift force of the weight opposing main push-towing rope of anchorage self, relies on the horizontal force of frictional force opposing main push-towing rope between anchorage and basis.When anchorage place geological conditions was bad, traditional gravity anchor needed bigger engineering size, and engineering quantitys such as excavation of foundation pit, ground processing are huge simultaneously, and the construction period is longer, in work progress, also had bigger construction risk.Medium and small suspension bridge of striding the footpath under the little situation of main push-towing rope power, can adopt special anchorage structure, solves engineering cost and construction risk problem.
The utility model content
The utility model technical problem to be solved provides medium and small span suspension bridge anchorage structure under a kind of weak geological conditions, can avoid construction risk effectively, reduces difficulty of construction and construction costs.
It is following that the utility model solves the technical scheme that its technical problem adopted:
Medium and small span suspension bridge anchorage structure under the weak geological conditions of the utility model; Comprise anchorage; It is characterized in that: said anchorage below is provided with the be multi-column pier foundation of one fixed with it; The cushion cap that this multi-column pier foundation is embedded in the foundation pile in the soft foundation soil body by vertical, lateral separation and is consolidated in its top constitutes, and the cushion cap bottom surface contacts with the soft foundation soil body.
The beneficial effect of the utility model is, the anchorage size reduces greatly, need not carry out deep pit digging, supporting and soft foundation is handled, and can avoid construction risk effectively, reduces difficulty of construction and construction costs, helps simultaneously shortening the construction period.
Description of drawings
This manual comprises following three width of cloth accompanying drawings:
Fig. 1 is the elevational schematic view of medium and small span suspension bridge anchorage structure under the weak geological conditions of the utility model;
Fig. 2 is the lateral view of medium and small span suspension bridge anchorage structure under the weak geological conditions of the utility model;
Fig. 3 is the vertical view of medium and small span suspension bridge anchorage structure under the weak geological conditions of the utility model.
Member shown in the figure, toponym and pairing mark: anchorage 10, cushion cap 20, foundation pile 30, anterior foundation pile 30a, rear portion foundation pile 30b.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
See figures.1.and.2; Medium and small span suspension bridge anchorage structure under the weak geological conditions of the utility model; Comprise anchorage 10; Below anchorage 10, being provided with fixed with it is the multi-column pier foundation of one, and the cushion cap 20 that this multi-column pier foundation is embedded in the foundation pile 30 in the soft foundation soil body by vertical, lateral separation and is consolidated in its top constitutes, and cushion cap 20 bottom surfaces contact with the soft foundation soil body.Uplift force by anchorage 10, cushion cap 20 opposing main rope of suspension bridge; The horizontal force of main push-towing rope is born by the clump of piles under the cushion cap 20; Therefore can reduce anchorage 10 sizes greatly, and need not carry out deep pit digging, supporting and soft foundation handled, so can avoid construction risk effectively; Reduce difficulty of construction and construction costs, help simultaneously shortening the construction period.
With reference to Fig. 1, said foundation pile 30 comprises anterior foundation pile 30a and the rear portion foundation pile 30b that is separately positioned on cushion cap 20 lower front, lower rear, and pile foundation all adopts the socketed pile design, and pile foundation is imbedded the degree of depth of basement rock and confirmed according to basement rock weathering line.
With reference to Fig. 1, Fig. 2 and Fig. 3; Anchorage 10 is structurally consistent with traditional gravity anchor; Can be divided into anchor chamber, male cone body, sealing off and covering anchorage section, saddle weight four parts, be variable cross-section wedge shape rib body, anchor chamber, male cone body, sealing off and covering anchorage section are mainly born the effect of main rope of suspension bridge power transition in anchorage.Said foundation pile 30 adopts the stake hole pouring pile usually, and it is identical with traditional bridge pile foundation construction to construct.
Some principles of medium and small span suspension bridge anchorage structure under the weak geological conditions of the above the utility model that just explains through diagrams; Be not be to the utility model be confined to shown in described concrete structure and the scope of application in; So every the modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
Claims (2)
