Abstract

The utility model discloses a pier protection device, which is characterized in that a back-to-water surface and a face-to-water surface of a pier are respectively provided with a horned water guide part and a water diversion part, and the front end of the water guide part is wrapped with a protection unit; and the protection unit comprises an inner protective layer and an outer protective layer, the inner protective layer is combined on the water guide part, the outer protective layer is combined on the inner protective layer, and a buffer layer is arranged between the inner protective layer and the outer protective layer. When the face-to-water surface of the pier is impacted by lots of rushed water flows or mud-rock flows, the water flows or mud-rock flows can be separated with the aid of the horned protection unit, thereby greatly reducing the impact on the face-to-water surface; and the buffer layer has a function of absorbing an impact force, and then protects the pier from being damaged.

Description

A kind of bridge pier protector

Technical field

The utility model relates to a kind of bridge pier protector.

Background technology

The high water in mountain, China south is anxious, and typhoon or heavy rain always form mud-rock flow, and the serious consequence that mud-rock flow brings comprises that road damages, particularly bridge fracture; Present large bridge, majority are designs before 20,30 years, and based on the consideration of economy; Weather, the rainfall of adding originally are different fully with now, so the bridge of design is that many bridge piers, span are little, such bridge design is easy, cost is little; But because ground is little, steady inadequately; Can't bear heavy rain and wash away, surpass the intrinsic capacity of bridge, cause bridge to can't bear to load and rupture: to pass by relevant unit simultaneously when design mountain area cross a river road and bridge; Only consider the water level and the flow velocity of streams flood, do not take into full account the quite big mud-rock flow shock effect of flood phenomenon difference.

In addition, common bridge pier design is as shown in Figure 1 mostly, and the section of the pier body 1 of this bridge pier is similar cylindric, and upstream face 11 and back side 12 all are circular arc.When bridge pier was by flood erosion at every turn, its upstream face 11 can receive sizable water impact, and can form eddy-currents at back side 12 places, and then was emptied under causing bridge pier; Simultaneously in recent years because the excessive exploitation in mountain area, when a large amount of rainwater rapid drawdown took place, regular meeting was accompanied by a large amount of mud-rock flows and pours down, and not only can cause serious alluvial to the rivers and creeks, more can cause serious impact to the bridge pier of bridge.

Summary of the invention

Therefore; For problems such as the upstream face that improves above-mentioned bridge pier bear the impact of too big current or mud-rock flow and reduces that the beneath quilt in basis is emptied; The utility model provides a kind of bridge pier protector; In water guide sector and diversion portion that the upstream face and the back side of bridge pier is provided with horn shape, the water guide sector front end is coated with the protective unit that plays the strengthening structure effect.

The technical scheme that the utility model adopts is following; A kind of bridge pier protector includes the bridge pier pier body of upstream face and back side, and its upstream face place is provided with the water guide sector that is horn shape; And be coated with protective unit in this water guide sector front end appearance; This protective unit comprises the protection nexine that combines with the pier body, and the protection that combines with the protection nexine is outer, this protection nexine and protect between the skin and be provided with cushion coat.

Therefore; The protection nexine that is coated successively from inside to outside, cushion coat and protection by the front end place, water guide sector of the upstream face horn shape of above-mentioned bridge pier are outer, let the bridge pier upstream face receive in a large number, rapidly during the impact of current or mud-rock flow, except can be separately with current or mud-rock flow; Outside the impact that significantly reduces upstream face and born; Also have the effect of relax impacting simultaneously concurrently, and then protect bridge pier, avoid the damage and the fracture of bridge, can reduce the phenomenon of being emptied under the basis simultaneously again.

The specific embodiment

Referring to Fig. 2-3; The both sides, front and back of the bridge pier pier body 1 of the utility model respectively are a upstream face 11 and a back side 12; And be respectively equipped with water guide sector 13 and the diversion portion 14 that is dihedral at this upstream face 11 and back side 12, and the appearance of 13 front ends coats a protective unit in the water guide sector. this protective unit comprises the protection nexine 15 that combines with the concrete of the water guide sector 13 of pier body 1.Locations at predetermined place outside this protection nexine 15 is respectively equipped with recess 151 and protuberance 152.Also coat a protection outer 16 in the outside of protection nexine 15.Inner surface and the recess 151 of protection nexine 15 and the relative position of protuberance 152 in protection outer 16 are provided with mutual correspondence and can be mounted in protuberance 161 and recess 162 together each other.

Between protection nexine 15 and protection outer 16, also be provided with cushion coat 17.

Like this; The horn shape protective unit that is coated by water guide sector 13 front ends of the upstream face horn shape of above-mentioned bridge pier; Let to the upstream face of bridge pier 11 produce impact in a large number, current or mud-rock flow rapidly, can be with it separately and guiding, and then significantly reduce the impact strength that upstream face 11 is born by the horn shape protective unit; While is by the absorption of cushion coat 17 impact power; Current or mud-rock flow are cushioned the bump of bridge pier, thus can protect the bridge pier main body to avoid the destruction of being impacted really, and then guarantee the safety of bridge.

Back side 12 is provided with the diversion portion 14 that is horn shape equally, makes its generation that can avoid eddy-currents, and then can reduce the phenomenon of being emptied under the pier footing.

In addition; Referring to Fig. 4, the front end horn shape place of protection outer 16 is preceding guiding element 16a, and preceding guiding element 16a two rear ends are connected side guiding element 16b; And preceding guiding element 16a and protection be provided with equally between the nexine 15 can be chimeric each other recess 162 and protuberance 152; Also be provided with between side guiding element 16b and the protection nexine 15 in addition can be chimeric each other protuberance 161 and recess 151, the joining place between preceding guiding element 16a of while and the side guiding element 16b is provided with and is corresponding ladder and together the portion of splicing 163,164 of can being superimposed with each other.

Thus; This protection outer 16 is made up of preceding guiding element 16a and side guiding element 16b, like this, is positioned at the upstream face place owing to protect skin 16; Its front end stands in the breach and receives the bump of mudstone; So more or less freely impaired, so protection outer 16 can be changed according to the position of actual damage, so can reduce the easy property of material unaccounted-for (MUF), reduction maintenance cost and increase maintenance.

Fig. 5 has shown another embodiment of the utility model.Different with the foregoing description is that with retaining element 18, for example screw is fixed in chimeric each other recess and protuberance.
