Abstract
The invention discloses an integrally curved surface-shaped pier anti-collision floating type casing box. The pier anti-collision floating type casing box is obtained by splicing and enclosing a plurality of independently sealed box bodies with elliptic sections through joints; the box bodies are made of sandwich plates; and the sandwich plates are obtained by using polyurethane as sandwich layers and steel plates as panels. The pier anti-collision floating type casing box is integrally curved surface-shaped and sleeved on a pier like a rubber kayak or a life buoy; the sections of the box bodies can be also designed in elliptic or circular shapes according to the size of a ship; the casing box totally has better elastic performance; a ship bow is easy to shift to change the direction when impact kinetic energy is absorbed; and a horizontal collision force is decomposed, so that energy is exchanged among the ship, the anti-collision casing box and the pier and a protective effect on each party is achieved. As the box bodies are manufactured by using the sandwich plates with stronger anti-impact capacities, stiffening structures can be not arranged or less stiffening structures can be arranged; therefore, defects that a large amount of stiffening plates and brackets must be arranged in a common buoyancy tank and the exterior of the common buoyancy tank only can be formed by combining a plurality of planes in order to guarantee necessary strength and rigidity are overcome.
Description
Technical field
The present invention relates to the anticollision device of pier of cruiseway, relate in particular to the pier anticollision floating casing that a kind of integral body is curved.
Background technology
In the navigable river, the accident of ship collision bridge pier exists for a long time and at large, and bridge and navigation safe operation have been caused very large harm.Although it is less that ship hits the accident that occurs collapsing behind the bridge,, the consequence that ship hits the bridge accident remains shocking.For the bridge of building on the boats and ships tonne little cruiseway, because water level, change in flow are large, need a kind of volume not too large, do not account for the navigation channel, buoyancy is large, pushes easily fore aside, the pier anticollision casing that shock resistance is good, existing various anti-collision facility are all undesirable to above-mentioned requirements.
Summary of the invention
The object of the invention is to overcome the shortcoming and defect of prior art, a kind of pier anticollision floating casing that has the excellent impact resistance energy, is curved from the integral body of heavy and light, good springiness is provided, this pier anticollision floating casing is easily pushed fore aside and is changed the shipping agency direction, the decomposition level impact can absorb boats and ships more to the impact energy of bridge pier.
The present invention is achieved through the following technical solutions:
A kind of integral body is the pier anticollision floating casing of curved, and this pier anticollision floating casing is to be surrounded by the joint splicing by the casing of the independent sealed cross sectional shape ovalize of multistage; The material of described casing is sandwich slab, and this sandwich slab is that laminboard layer, steel plate are that the sandwich slab of panel forms by polyurethane.
Described joint is oval flanged ends.
The present invention has the following advantages compared with prior art:
Monnolithic case of the present invention is curve form; rubber like kayak or lifebuoy are enclosed within on the bridge pier; the cross section of casing is oval; preferably elastic performance is totally arranged, lightweight, in the time of impact-absorbing kinetic energy; easily push fore aside and change the shipping agency direction; the decomposition level impact effectively realizes the energy exchange of boats and ships, anti-collision jacket and bridge pier, and each side is shielded.
(2) casing adopts the stronger sandwich slab manufacturing of impact resistance, its polyurethane is that laminboard layer, steel plate are panel, the casing that this sandwich slab material is made, can be not if establish less stiffening construction, overcome common buoyancy tank in order to guarantee necessary strength and stiffness, must a large amount of stiffeners and support be set in inside, the casing profile is difficult to make curve form, can only make the poor shortcoming of impact resistance that many flat shapes are brought.Adopt the casing of this patent sandwich slab manufacturing to have province's steel, from advantages such as heavy and light, welding job amount are few.
(3) pier anticollision floating casing of the present invention adopts the independent sealed casing of multistage to surround processing, transportation, easy construction by the joint splicing.
Description of drawings
Fig. 1 is the structural plan schematic diagram that integral body of the present invention is the pier anticollision floating casing of curved;
Fig. 2 is A-A schematic cross-section among Fig. 1, i.e. casing 1 cross section structure schematic diagram.
The specific embodiment
Below in conjunction with specific embodiment the present invention is done further concrete detailed description the in detail.
Embodiment
As shown in Figure 1 and Figure 2, integral body of the present invention is the pier anticollision floating casing of curved, and this pier anticollision floating casing is to be surrounded by joint 2 splicings by the casing 1 of the independent sealed cross sectional shape ovalize of multistage; The material of making casing 1 adopts sandwich slab, and this sandwich slab is that laminboard layer 1-1, steel plate 1-2 are that the sandwich slab of panel forms by polyurethane.This pier anticollision floating casing because its monnolithic case is curve form, is easily pushed fore aside and is changed the shipping agency direction, and the decomposition level impact effectively realizes the energy exchange of boats and ships, casing 1 and bridge pier, and each side is shielded.
Described joint 2 is oval flanged ends, have quick and easy for installation, the time and labour saving.
Pier anticollision floating casing profile also can be decided according to the bridge pier column shape, and such as being rectangle with rounded head, its overall dimensions is decided by the pier shaft sectional dimension.
At casing 1 and the contact surface of bridge pier 4 rubber fender piece 3 is installed, in order to improve pier anticollision floating casing impact-absorbing kinetic energy, is better protected bridge pier.
The casing 1 of cross sectional shape ovalize also can also can adopt circle according to the boats and ships size, and its sectional dimension is determined by stressed size and ship collision situation etc.
The steel plate 1-2 thickness of sandwich slab and the thickness of sandwich sandwich layer 1-1 can require to determine according to designing and calculating.
This sandwich slab is to pour into hard polyaminoester between two-layered steel plates 1-2, need to prove, the bonding surface of perfusion front spring 1-2 and hard polyaminoester need through blasting treatment, with rust cleaning and increase roughness, guarantee that hard polyaminoester solidifies the adhesion strength of rear and steel plate 1-2 inner surface.The modulus of elasticity of hard polyaminoester is about 700MPa～800MPa, and proportion is about 11kN/m
3～12kN/m
3
This integral body is the pier anticollision floating casing of curved, but factory make, the site assembly construction, the duration is short, casing 1 fluctuates with water level, is suitable for inland river pier anticollision facility on the navigation channel below three grades.
Embodiments of the present invention are not restricted to the described embodiments; other are any not to deviate from change, the modification done under Spirit Essence of the present invention and the principle, substitute, combination, simplify; all should be the substitute mode of equivalence, be included within protection scope of the present invention.
