Abstract
A pier collision preventing and energy dissipation device capable of ascending and descending automatically comprises a pier and is characterized by being composed of an annular protection sleeve, connecting springs, sliding blocks and guide rails. The guide rails are arranged on the outer wall of the pier, the axial direction of the guide rails is parallel to the axial direction of the pier, and the guide rails are distributed in the circumferential direction of the pier. The sliding blocks and the guide rails are in sliding connection, and the sliding blocks correspond to the guide rails one to one. The annular protection sleeve is connected outside the pier in a sleeved mode, and a clearance is reserved between the annular protection sleeve and the pier. One end of each connecting spring is connected with the inner circumferential face of the annular protection sleeve, the other ends of the connecting springs are connected with the sliding blocks, the connecting springs correspond to the sliding blocks one to one, and the connecting springs are distributed in the circumferential direction of the annular protection sleeve. The pier collision preventing and energy dissipation device has the advantages that the protection device can move along with the variation of the water level, the structural utilization rate of the protection device is greatly improved, the protection device is prevented from being arranged on the whole pier in the length direction, construction cost is low, and the protection effect is good.
Description
Technical field
The present invention relates to a kind of aquatic building guard technology, particularly relate to a kind of pier anticollision energy dissipator of energy automatic lifting.
Background technology
It is huge with navigation safety hazard to bridge structure safe that boats and ships or drift clash into bridge pier accident; For this kind of accident, traditional safeguard procedures or be avoid making bridge pier be arranged in navigable waters, that restriction is taked to navigation ship, also some even prevents damaged in collision by improving the rigidity of bridge pier self, and these safeguard procedures increase requirement to navigation ship and bridge construction cost.
In recent years, occur that polytype protection is arranged both at home and abroad, a kind of anti-impacting bearing pile for bridge battle array disclosed in No. 200610155224 Chinese patent, the program relies on the buffering deflection of single rubber fenders to play protective action, protection effect is comparatively limited, can effectively play a protective role for small boat or less drift, but impact cannot be absorbed well for the large ship of tonnage more than hundred tons, unavoidable breakage still kept away by bridge pier, and due to the position of rubber fenders relatively-stationary, for SEA LEVEL VARIATION waters comparatively frequently, need to arrange that more rubber fenders is to cover bridge pier surface, difficulty in installation and layout, too increase production and maintenance cost.Conventional anticollision device, collision-prevention device also has pile group mode, shell builds husky cofferdam mode, man-made island mode etc., these modes are generally all only applicable to that water is shallow, the good occasion of geological condition, although put things right once and for all, can navigation channel be affected, and usually because cost is too high or condition does not possess and abandons.The employing casing energy-dissipating installation also had; utilize the damaged energy dissipating of casing plastic strain; but it can only bear single impact usually; keep in repair more difficult after damage; the protection to hull is not considered during collision; maintenance cost is higher, does not consider that the position of collision difference of bridge pier during fluctuation in stage makes Anti-bumping protection cost increase.There is the automatic lifting anticollision device, collision-prevention device independent of bridge pier in recent years, comparatively abundant to shielded bridge pier protection, but need newly-built anti-collision structure, drop into comparatively large, need newly-built independent reinforced concrete structure, the construction period is longer.
In prior art, pier section is generally rectangle or circle, and when bridge pier adopts this two kinds of section forms, linking springs also can adopt following preferred arrangement: described pier section is rectangle, and linking springs is axially vertical with bridge pier surface.Described pier section is circular, and linking springs axially overlaps with the radial direction of bridge pier.
Advantageous Effects of the present invention is: protector can following water-level lifting and moving, and substantially increase the Fabric utilization of protector, avoid and need total length on bridge pier to arrange protector, implementation cost is lower, and protection effect is better.
Summary of the invention
For the problem in background technology, the present invention proposes a kind of pier anticollision energy dissipator of energy automatic lifting, comprise bridge pier, its innovation is: the pier anticollision energy dissipator of described energy automatic lifting is made up of annular shield cover, many linking springs, multiple slide block and Duo Gen guide rails; Described guide rail is arranged on bridge pier outer wall, and lead rail axis is to axially parallel with bridge pier, and many guide rails are along the distribution of bridge pier circumference; Described slide block is connected with slide, multiple slide block and many guide rail one_to_one corresponding; Described annular shield cover is socketed in outside bridge pier, leaves gap between annular shield cover and bridge pier; The inner peripheral surface that one end and the annular shield of linking springs overlap is connected, and the other end of linking springs is connected with slide block, many linking springs and multiple slide block one_to_one corresponding, many linking springs annularly protective jacket circumference distributions.
Function of the present invention has two, one, protection bridge pier is from damaged in collision, they are two years old, the position of annular shield cover can move up and down with SEA LEVEL VARIATION, substantially increase the utilization rate of safeguard structure, specifically, aforementioned two functions are achieved in that the annular shield cover be socketed in outside bridge pier is the core of anti-collision structure, it can carry out omnidirectional's protection of 360 degree to bridge pier, and due to many linking springs be all connected to annular shield cover inner peripheral surface on, many linking springs and annular shield cover define in fact overall force structure, when a collision occurs, the percussion of collision can be shared jointly by many linking springs, improve the assimilation effect of safeguard structure to striking momentum, make safeguard structure can bear larger percussion, in addition, the junction of safeguard structure and bridge pier is provided with slide block and guide rail, when SEA LEVEL VARIATION, slide block and annular shield cover also at water body buoyancy float downward or can move down, this just makes annular shield cover be positioned at all the time near the water surface, in prior art, in SEA LEVEL VARIATION waters frequently, in order to all protect bridge pier total length, need all to arrange safeguard structure in bridge pier total length, and after adopting the solution of the present invention, only need an annular shield cover, just can realize the protection to bridge pier total length, Fabric utilization is very high.
In order to improve the assimilation effect of annular shield cover to impact energy further, preferably, described annular shield cover adopts elastomeric material to make.
On aforementioned schemes basis, also by described annular shield cover is set to the energy-absorbing function that hollow tubular structure improves structure further.
Similarly, described slide block also adopts elastomeric material to make to the improvement project of overlapping with annular shield, in addition, also can arrange cavity in described slide block.
