Abstract
The utility model discloses a pier anti-collision floating protecting box with a whole presenting curved-surface shaped. The pier anti-collision floating protecting box is spliced and surrounded by a plurality of independent box bodies through joints, wherein cross sections of the plurality of independent box bodies are elliptical shaped. The box bodies are made of sandwich plates. The sandwich plates consist of polyurethane sandwiching core layers and steel face plates. The whole appearance of the pier anti-collision floating protecting box is in a curved-surface shape and is similar to a rubber kayak or a cork hoop. The pier anti-collision floating protecting box is sleeved on a pier. The cross section of the box body can be designed into an elliptical shape or a circular shape according to the size of a ship. The whole appearance has good elastic property. Impact kinetic energy can be absorbed and a nose is easy to push aside so as to change the direction of ship voyage. Level impact force can be decomposed. Energy exchange of the ship, the pier anti-collision floating protecting box and the pier is achieved. Protective effects to each part are achieved. The box body is made of sandwich plates, wherein the sandwich plates are strong in impact resistance property. Stiffening structures can not be installed or a small amount of reinforcement structures can be installed. The defects that a large amount of stiffening plates and supports are installed in the interior of a common buoyancy tank to guarantee necessary strength and stiffness and the appearance can only be combined by multiple planes are overcome.
Description
Technical field
The utility model relates to the anticollision device of pier of cruiseway, relates in particular to the pier anticollision floating casing that a kind of integral body is curved surface shaped.
Background technology
In 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 after bridge,, the consequence that ship hits the bridge accident remains shocking.For the bridge of building on 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, easily pushes 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 purpose of this utility model 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 surface shaped 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 utility model is achieved through the following technical solutions:
A kind of integral body is the pier anticollision floating casing of curved surface shaped, and this pier anticollision floating casing is that the casing by the independent sealed cross sectional shape ovalize of multistage splices by joint and surrounds; 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 utility model has the following advantages compared with prior art:
The utility model monnolithic case is curve form; rubber like kayak or lifebuoy are enclosed within on bridge pier; the cross section of casing is oval; elastic performance is preferably 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 utility model adopts the independent sealed casing of multistage to splice by joint and surrounds, processing, transportation, easy construction.
Description of drawings
Fig. 1 is the structural plan schematic diagram that the utility model integral body is the pier anticollision floating casing of curved surface shaped;
Fig. 2 is A-A schematic cross-section in Fig. 1, i.e. casing 1 cross section structure schematic diagram.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is done further concrete detailed description the in detail.
Embodiment
As shown in Figure 1 and Figure 2, the utility model integral body is the pier anticollision floating casing of curved surface shaped, 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.
Rubber fender piece 3 is installed on the contact surface of casing 1 and bridge pier 4, 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 surface shaped, but factory's manufacturing, the site assembly construction, the duration is short, and casing 1 fluctuates with water level, is suitable for inland river pier anticollision facility on the navigation channel below three grades.
Embodiment of the present utility model is not restricted to the described embodiments; other are any does not deviate from change, the modification done under Spirit Essence of the present utility model and principle, substitute, combination, simplify; all should be the substitute mode of equivalence, within being included in protection domain of the present utility model.
