Along with the fast development that China's cross a river, Oversea bridge are built, open caisson foundation have also been obtained to be applied more and more widely, and such as Nanjing Yangtze River Bridge, Jiangyin Yangtse River suspension bridge, Ma'an Mountain's Yangtze Bridge all have employed dissimilar open caisson foundation.Open caisson is a kind of rigidity deep foundation, does not need separately to establish to go along with sb. to guard him facility during construction, and open caisson foundation has the advantages that buried depth is large, resistance to overturning is good, can bear larger vertical load and horizontal loading, be particularly useful for deep water foundation.The work progress of open caisson does not need very complicated plant equipment, and construction technology is simple, can full-face tunneling.
In prior art, large bridge open caisson foundation mainly adopts rectangle, nose circle shape, circle and rectangle rounding section open caisson, when being applied in the river or coastal waters bridge engineering with navigation requirement, due to large bridge open caisson foundation enormous size, make open caisson foundation very large to the resistance effect of current, rectangular cross section open caisson four limit is straight line, direction of ship travel cannot be changed during ship collision, be unfavorable for structural collision protection and the protection to hull, and the linear borehole wall is unfavorable for structure stress, nose circle shape or circular cross section open caisson block water, and comparatively rectangular open caisson is good for effect, and due to the Curve Design of nose circle shape or circular cross section open caisson periphery, certain effect changing direction of ship travel is had during ship collision, be conducive to structural collision protection and the protection to hull, but because bridge construction is stressed and structure needs, main pier along bridge to completely different with direction across bridge both direction arrangement form, cause open caisson foundation at suitable bridge to larger with the size difference of direction across bridge, as adopted circular cross section open caisson, only have open caisson larger, strengthen the demand that project scale meets long side direction, and the waste of short side direction size is too many, this certainly will cause very large waste, and its arc radius is larger, change the effect of hitting bridge ship course very unobvious.
Summary of the invention
The object of this invention is to provide the one effect that blocks water little, can change easily and hit bridge ship course, reduce impact, alleviate the damage of knockout process Bridge and boats and ships, and along bridge to coordinating mutually with lateral dimension and required size, project scale is reasonably beneficial to the flat ellipse bridge open caisson foundation changing and hit bridge ship course.
Above-mentioned purpose of the present invention is achieved by the following technical solution: a kind of be beneficial to change hit the flat ellipse bridge open caisson foundation of bridge ship course, comprise wellhole in the borehole wall, minor face partition wall, long limit partition wall, arch end hole hole, rectangle, the borehole wall, long limit partition wall and minor face partition wall are linked to be entirety, in arch end hole hole and rectangle, wellhole is distributed in wherein, forms lattice flat ellipse section open caisson foundation.
Borehole wall profile of the present invention is flat ellipse, and long limit partition wall and minor face partition wall are linear.
Many long limit partition walls, minor face partition wall and wellholes of the present invention surround several arch end hole holes.
Many long limit partition walls of the present invention and minor face partition wall surround wellhole in several rectangles.
Of the present invention being beneficial to changes the flat ellipse long limit Parallel to the flow direction hitting the flat ellipse bridge open caisson foundation of bridge ship course and arranges.
Compared with prior art, the present invention has following remarkable result:
The present invention is beneficial to change and hits the flat ellipse bridge open caisson foundation of bridge ship course compared with rectangle and rectangle rounding section open caisson foundation, has following characteristics:
(1) the present invention is beneficial to the flat ellipse bridge open caisson foundation changing and hit bridge ship course, and adopt sharp convex airflow design, the effect that blocks water significantly reduces;
(2) the present invention is beneficial to the flat ellipse bridge open caisson foundation changing and hit bridge ship course, and the stream profile that meets water is that point is convex streamlined, during ship collision, ship turning out of control can be induced, reduce ship impact force, structural collision protection performance is good, and hull damage when effectively can reduce shock;
(3) the present invention is beneficial to the flat ellipse bridge open caisson foundation changing and hit bridge ship course, and the borehole wall is convex outer curve shape, and arch end hole hole is lateral opening compared with rectangle stressed more favourable to the borehole wall, can effectively resist deep-water pressure and soil pressure.
The present invention is beneficial to change and hits the flat ellipse bridge open caisson foundation of bridge ship course compared with nose circle shape or circular cross section open caisson foundation, has following characteristics:
(1) the present invention is beneficial to change and hits the flat ellipse bridge open caisson foundation of bridge ship course, and flat ellipse long limit Parallel to the flow direction is arranged, less compared with the rounded outer profiles effect that blocks water, and anti-collision effect is better;
(2) the present invention is beneficial to change and hits the flat ellipse bridge open caisson foundation of bridge ship course, along bridge to coordinating mutually with lateral dimension and required size, project scale is more reasonable.
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
