According to the invention, the mixed diaphragm wall is converted to a permanent load-carrying structure to bear tension of a main cable with the inside lining, the baseplate and the top plate commonly from a temporary enclosing structure, the scale of the anchorage foundation of a suspension bridge is reduced, and the anti-sliding, anti-overturning and stability of the foundation are strengthened.
Description
Technical field
The invention belongs to bridge technology field, be specifically related to the new structure on a kind of Bridge anchorage basis, particularly the common stressed Compound Anchorage basis of a kind of hybrid ground-connecting-wall and gravity anchor.
Background technology
Diaphragm Wall is widely used in the Bridge anchorage foundation supporting structure of China, circular diaphragm wall anchorage supporting and protection structure, the diaphragm wall anchorage supporting and protection structure of Huangpu Bridge over Zhujiang River and the diaphragm wall anchorage supporting and protection structure of parrot continent, Wuhan bridge successively having built up profit and raise bridge freezing process diaphragm wall anchorage supporting and protection structure, sun and patrol bridge diameter 73m.
Although these traditional continuous underground wall structures are also by ingredients such as body of wall, liner, base plate, top boards.In design, diaphragm wall, only as the space enclosing structure of anchorage foundation ditch, plays the effect of gear soil, dash, and therefore general body of wall is upper and lower elongated reinforced concrete structure, and liner is also upper and lower elongated reinforced concrete structure.Body of wall, liner connect and connect by common straight thread reinforced bar connector, and base plate connects with the reinforcing bar that is connected the 10cm～20cm length by inserting liner of liner, and body of wall, liner and base plate do not form one.This connected mode is also unreliable, under horizontal force action, the delivery position at delivery position, rear side body of wall and the base plate top of front side body of wall and base plate bottom is stressed more concentrated, easily there is crack and corrosion, therefore in design in the past not using diaphragm wall as a permanent stressed part, as one " ∞ " the shape Diaphragm Wall Support Structure of patent CN201809785U introduction, still, as a kind of space enclosing structure, do not participate in permanent structure stressed.
In construction work, consider that supporting and protection structure participates in stressed " the two walls unification " technical development of permanent structure as outer wall of basement very fast, in a lot of highrise buildings of soft foundation, arrive application.Also there is the patent (CN203613565U, CN103615017A) of the aspect such as relevant raft plate and hybrid ground-connecting-wall link technique, Guan Liang and hybrid ground-connecting-wall link technique.But the permanent force status on Bridge anchorage basis is taking the horizontal force of main push-towing rope as main, and horizontal loading is huge, with the vertical applied force in construction work be that main feature has very large difference.Therefore require higher to diaphragm wall with the structure that is connected of base plate.In addition Bridge anchorage basis is larger, and as the diameter of the circular diaphragm wall planar rondure outline of Humen Er Qiao anchorage reaches 90m, the thickness of hybrid ground-connecting-wall, inside lining, top board and base plate is all thick a lot of than the diaphragm wall of construction work.Must adopt new connection structure, just can make hybrid ground-connecting-wall and gravity anchor can form composite foundation.
In recent years, rapid in the hybrid ground-connecting-wall technical development of Japanese steel, adopt some small-sized i shaped steels to interconnect to replace longitudinal reinforcement, have advantages of that rigidity is large, wall section is little, take up an area and economize.Domestic improvement and the application that has also progressively occurred this class technology at present, as CN103233459A patent has proposed " a kind of two-in-one double steel plate Combined concrete diaphragm wall and construction method thereof ".This technology is applied in following several problem in Analysis of Suspension Bridges ' Anchorage diaphragm wall: what 1, the steel diaphragm wall of Japan adopted is that small-sized i iron is connected to form a groove section piecemeal, and work efficiency is lower, is applicable to minor works and narrow place; 2, the plate of domestic combination diaphragm wall patented technology is still unreliable with being connected of wall, and this patent adopts beam reinforced steel bar to be welded direct on the steel plate of hybrid ground-connecting-wall to connect, under the effect of significant horizontal power, easily break; 3, within the scope of full height, adopt combination diaphragm wall, economy is poor.
