Technical field
The utility model relates to the bridge security field, particularly a kind of anticollision device, collision-prevention device for the protection of bridge pier safety.
Background technology
The acceleration of the development of land communications transport service, particularly urban interchange and high speed railway construction, the bridge that stands on identitypath is more and more, so that the accident of Vehicular impact bridge pier sharply increases, existing many bridges are scarred because of the bump of vehicle.In order to ensure bridge security, must research collide mechanism, the bridge-collision-avoidance facility is set.
Early stage in bridge engineering development is because the special status of water route transportation so that the situation that may cause bridge pier to damage in the collision of ship and bridge pier and this process has caused related personnel's concern, also has been born thus and has prevented in a large number ship collision devices and avoiding collisions.Because the development of early stage highway bridge construction is comparatively slow, the research starting of highway bridge anticollision device, collision-prevention device is evening relatively, from existing device, only has a small amount of several design forms simultaneously.In recent decades, along with the fast development of city intersection construction process and auto industry, the importance of highway bridge Bridge Pier obtains extensive concern.Consider the finiteness in highway bridge available design space, the method for designing of directly using the bridge anticollision device, collision-prevention device is worthless, need to according to the particularity of highway bridge applied environment, take into full account its actual application conditions.
Summary of the invention
The utility model is optimized on the basis of existing anticollision device, collision-prevention device design concept, and a kind of anticollision device of pier with flexible energy function is provided.This device has taken into full account projected angle of impact possible under the practical application condition on routine evenly distributes the basis of power consumption material, the mode by the uneven distribution material takes full advantage of the material dissipation Impact energy in the device.This device makes it possible in the protection bridge pier vehicle and occupant effectively be protected by use and the special configuration design of flexible material.
The flexible energy anticollision device of pier, comprise outer box hat 1, upper cover plate 2, built-in box hat 3 and 4, the core body 5 that the flexible energy material forms, precast concrete boss 6, it is characterized in that concrete boss 6 pours into a mould centered by bridge pier, core body 5 is installed on the concrete boss 6 and is with pre-manufactured hole, two pre-manufactured holes of symmetrical reservation along core body 5 major axis two ends, the major axis bilateral symmetry is reserved four pre-manufactured holes, the pre-manufactured hole of two built-in box hats 3 and four built-in box hat 4 insertion core bodys 5 also is fixed on the concrete boss 6, outer box hat 1 is looped around core body 5 peripheries, be fixedly connected with concrete boss 6 usefulness, upper cover plate 2 is fixedly connected on built-in box hat 3 and 4, and be fixedly connected with outer box hat 1, upper cover plate 2 covers built-in box hat 3 and 4 and core body 5, outer box hat 1 and bridge pier upper end.
Being fixedly connected as wherein is hinged, angle steel connects or welding in a kind of.
The utility model has been obtained following technique effect:
1, the utility model structure and principle are simple, and cost is low, and collision prevention function is reliable and stable, long service life, and built-in core body can absorb well by its larger elastic-plastic deformation the energy of rammer; The arrangement of built-in box hat can comprise larger projected angle of impact preferably, and most impact energies are played preferably crashproof effect; Effectively disperse impact to make built-in core body produce larger distortion during outside box hat distortion of the design of upper cover plate, take full advantage of the material absorbing impact energy.
2, the lower convex platform of flexible energy anticollision device of pier design can be after device produces moderate finite deformation, and boss contacts with tire, by tire vehicle is produced one and upwarps power, and the simultaneously distortion of tire also can absorb part energy.
3, the design of ellipse or circular profile can make rammer change the direction that it is advanced along oval external surface generation slippage in the process of bump, avoid rammer along former direction generation resilience, particularly avoid the vehicle resilience to cause and the back vehicles or pedestrians between the generation of the second accident that causes of bump.
4, device adopts the mode of burst structure, can change comparatively easily repairing behind device experience bump, avoids unnecessary waste of material, saves maintenance cost.

The specific embodiment
The utility model will be further described below in conjunction with drawings and Examples.Should be appreciated that preferred embodiment only for the utility model is described, rather than in order to limit protection domain of the present utility model.
As shown in Figure 1, the utility model flexible energy anticollision device of pier comprises the precast concrete boss 6 of apparatus main body below; Install the outer box hat 1 of outermost ellipse; The ellipse core body 5 that is formed by the flexible energy material; Two pre-manufactured holes of symmetrical reservation along core body 5 major axis two ends, the major axis bilateral symmetry is reserved four pre-manufactured holes, and the pre-manufactured hole of two built-in box hats 3 and four built-in box hat 4 insertion core bodys 5 also is fixed on the concrete boss 6; Upper cover plate 2 covers built-in box hat 3 and 4 and core body 5, outer box hat 1 and bridge pier upper end.When this type device is set, oval major semiaxis direction is positioned over the position parallel with the major flow direction.
Before agent set is installed, precast concrete boss 6 around the required bridge pier 11 that this device is set; After concrete solidifies fully, the ellipse core body 5 of integral foam is installed according to the correspondence position of concrete boss at first; Then the built-in box hat 3 and 4 with different radii is welded on upper cover plate 2 relevant positions, afterwards the box hat 3 and 4 of different size is positioned at and presets position corresponding to concrete boss, and guarantee that the relevant position concrete inserts among the box hat 3 and 4, box hat 3 and 4 lower ends are played fixedly do preferably usefulness; After ellipse core body 5 and built-in box hat 3 and 4 installed, burst was installed the outer box hat 1 of ellipse, and it all adopts angle steel to be connected with the concrete boss, and is as shown in Figure 2, by angle steel 7 and anchor bolt 8 and bolt 9 that apparatus main body lower end and concrete boss 6 is fixed; Are connected connection with bolt with steel plate 10 shown in Figure 4 between the outer box hat of piecemeal; Install after the outer box hat, adopt the mode same with outer box hat is installed to be connected upper cover plate 2, such as Fig. 5, whole like this device installs.
After vehicle and device hit device, at first outer box hat 1 deforms, because outer box hat 1 links to each other with upper cover plate 2 in the upper end, the distortion of outer box hat 1 drives immediately upper cover plate 2 and built-in box hat 3 and 4 deforms, and in the deformation process of above-mentioned parts, cause the distortion of oval core body 5, take full advantage of the distortion energy dissipation capacity of device each several part, when the device distortion is larger, wheel and concrete boss 6 bump against, boss 6 produces one by tire to vehicle and upwarps power, simultaneously the further apparatus with shock absorbing that deforms of tire.
