Description
Technical field
The present invention relates to cofferdam fields.It is more particularly related to a kind of lock steel-pipe pile and I-shaped sheet pile group
Close cofferdam structure.
Background technique
With the continuous development of bridge foundation construction technology, bridge engineering construction is increasingly to deep water, the direction of large span
Development, the island cofferdam structure pattern of building of ultra-large type continue to bring out.Suspension bridge is as a kind of maximum bridge knot of current span ability
Configuration formula, its most of load are born by main push-towing rope, are dispersed on anchorage by strand and anchorage frame, then transmitted by Anchor Foundation
To ground.Therefore, the construction quality of Anchor Foundations of Suspension Bridge also becomes the control stress point of Excitations for Long Span Suspension bridge construction.
Currently, most of Anchor Foundations of Suspension Bridge are located at land both at home and abroad, and for Deepwater Open Sea bridge, anchor in suspension bridge water
Heavy stone used as an anchor foundation construction need to carry out first cofferdam and build island, convert land construction for over-water construction.It is marine super since cofferdam size is larger
Large-scale cofferdam construction will change the flow shape of local flow field, and the water velocity of cofferdam bottom is increase accordingly, and cause local punching
Brush, influences the stabilization of cofferdam structure itself.In addition, traditional builds island cofferdam structure in marine construction, wanted by water blocking rate
It asks, builds island cofferdam structure type selecting difficulty and gradually increase.
It is relatively conventional at present build island cofferdam structure pattern and can be divided into jackstone build island cofferdam, lock steel pipe pile cofferdam, lock
Steel sheet-pile cofferdam etc..It is easy that jackstone builds island cofferdam construction, but jackstone side's amount is big, and water blocking rate is high, gradually subtracts in heavy construction
It is few to use.It is big to latch the steel pipe pile cofferdam rigidity of structure, but consumption of materials is big, engineering cost is higher.Latch steel sheet-pile cofferdam material
Expect that consumption is smaller, engineering cost is lower, but structure stiffness by itself is smaller, and safety is poor.
