Fig. 2 is the structural representation of cross section of the anticollision device, collision-prevention device of the utility model bridge pier;
Fig. 3 is the front view of corrugated steel of the present utility model;
Fig. 4 is the enlarged diagram that in Fig. 1, A is ordered.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiments only is used for explanation the utility model and is not used in restriction scope of the present utility model, after reading the utility model, those skilled in the art all falls within the application's claim limited range to the modification of the various equivalent form of values of the present utility model.
As shown in Figure 1, the utility model discloses a kind of anticollision device, collision-prevention device of bridge pier.In the longitudinal sectional view of this anticollision device, collision-prevention device as seen: the anticollision device, collision-prevention device in this embodiment is comprised of three corrugated steel buffer layers, the most inboard corrugated steel buffer layer 2 is in a tubular form around the periphery of bridge pier 1, and adopt expansion bolt to fix, outermost corrugated steel buffer layer 4 also in a tubular form, the ripple trend of middle corrugated steel buffer layer 3 moves towards vertical with the ripple of innermost layer, outermost corrugated steel buffer layer.Ripple trend refers on the cross section of corrugated steel, and the tangential direction of a certain crest is if the waveform on cross section can use y=sin(x) expression, the ripple trend is the positive direction of x axle or opposite direction.In the utility model, tubulose comprises cylindrical tube, cuboid tubulose or other different forms, also or irregular.
Forward Fig. 2 to, in the cross sectional representation of another embodiment of this anticollision device, collision-prevention device as seen: corrugated steel buffer layer 2,3,4 is arranged in order.In other embodiments, corrugated steel buffer layer 2,3 position can be changed mutually, that is to say innermost layer the corrugated steel buffer layer the ripple trend can with the bridge pier Surface Vertical.
In conjunction with describing Fig. 3, corrugated steel of the present utility model surrounding have uniformly locating hole.
Fig. 4 is described at last, position relationship and annexation in the enlarged drawing that A is ordered between visible corrugated steel.In the figure, innermost layer and outermost corrugated steel buffer layer are shown as cross section, the tangent line of crest or trough and the Surface Vertical of bridge pier, and the Surface Vertical of the ripple of middle corrugated steel buffer layer 3 trend and bridge pier.In other embodiments, this anticollision device, collision-prevention device can also be set to more multi-layered, 2-8 layer for example, and the ripple trend of adjacent corrugated steel is mutually vertical.In the above-described embodiments, anticollision device, collision-prevention device is tubular, in actual applications, can be designed to other shapes such as rectangular-shaped or irregularly shaped according to actual conditions.
For overcoming the deficiency of background technology, utility model people provides a kind of plasticity, high strength, corrosion-resistant, the multilayer corrugated steel plate (pipe) that can be assembled into as requested difformity size and the easy construction anticollision device, collision-prevention device as bridge pier.The hard and soft merger of corrugated sheet steel has the ability of stronger absorption collision energy, and when bumping, moulding distortion occurs corrugated steel, stretches gradually, absorbs collision energy, the damage to the passenger can be dropped to minimum degree.In an embodiment, the anticollision device, collision-prevention device of corrugated steel tubular type bridge pier is divided into three layers, all adopts pin-connected panel corrugated steel (pipe), adopts between layers the high-strength corrosion-resisting bolt to connect, and the device internal layer is connected with expansion bolt with bridge pier; The internal layer of device and skin adopt hoop corrugated steel (pipe) spicing forming type around bridge pier, the vertical corrugated steel (pipe) that adopt in the intermediate layer, the damage of impact to bridge pier when further reducing to collide; On the road, the anticollision device, collision-prevention device of bridge pier is laid cement layer at the ground region of corrugated steel (pipe), connects the cement floor with screw, has so just increased the steadiness of corrugated steel (pipe).The structural representation of the corrugated steel that for this reason uses in anticollision device, collision-prevention device.Relative protective guard, corrugated steel tube not only intensity is large, corrosion-resistant, and the form of burst assembly unit makes installation very convenient.
That corrugated steel tube has is cheap, lightweight, easy construction, certain plasticity, compressive strength is high, intensity is large, the characteristics such as corrosion-resistant, can be widely used in the engineering road construction.To have corrosion resistance strong due to it, so can effectively protect bridge pier not to be subject to the erosion of corrosive substance in seawater (river) and the impact of silt.Impact in the time of more effectively subduing collision than individual layer corrugated steel tubular type anticollision device, collision-prevention device when multilayer corrugated steel pipe type anticollision device, collision-prevention device is impacted distortion; maximized protection bridge pier and accident vehicle (ship) are injury-free; and after damaging, replacing is convenient and swift, does not need professional construction equipment.Do not need traditional building material, the anti-collision facility after damage can recycling, environmental protection.
During construction, the anticollision device, collision-prevention device of corrugated steel tubular type bridge pier is according to from inside to outside, and order is from the bottom to top carried out assembly unit.First begin to install internal layer corrugated steel (pipe) bottom bridge pier, with the fixing corrugated steel (pipe) of high-strength bolt nut, on the road, anticollision device of pier can be connected corrugated steel with the ground pre-embedded bolt, and with expansion bolt, internal layer corrugated steel (pipe) is fixed on bridge pier, with the firm performance of stiffening device, the rest may be inferred, a section up installation, do not need to be installed to the top, till suitable height.Then coat weather proofing sealant, glue to be sealed after the assay was approved, beginning assembly unit intermediate layer corrugated steel (pipe), and with intermediate layer corrugated steel and internal layer corrugated steel with height doughtily bolt be connected, then the outer corrugated steel of assembly unit, method is identical with the internal layer erection method, and skin is connected with high-strength bolt with the intermediate layer, coat at last weather proofing sealant, be up to the standards.
