Description
Technical field
The utility model belongs to Pavement Skid Resistance field, is specifically related to a kind of ramp-type pedestrian overcrossing lower slope section non-slip ramp.
Background technology
Pedestrian overpass is as the just a large amount of construction of the crossing facilities of solid.It not only increases efficiency and the safety of pedestrian's street crossing, decreases the interference to arterial street traffic flow simultaneously, thus ensure that major urban arterial highway autos only ability.Part overline bridge lower slope section is designed to ramp-type and is beneficial to pedestrian and street crossed by bicycle, and the often anti-skidding setting of less consideration bridge floor when planning of conventional design method, causes having occurred larger problem in the use procedure in later stage.
Owing to there is certain gradient in city ramp-type pedestrian overcrossing, in addition when newly-built, anti-skidding process is not carried out to bridge floor, cause the attachment coefficient of bridge floor lower, especially under sleety weather, some bridge floor attachment coefficients without ceiling ramp-type pedestrian overcrossing drop to less than 0.15, and pedestrian and non motorized vehicle is under the impact of self gravitation, and health is difficult to keep balance, very easily produce slippery phenomenon, therefore this phenomenon needs improvement badly.
Research both domestic and external mainly concentrates on anti-slip material than choosing.Liu Maochun (1998) improves marking time of stair in the utility model patent of CN98218131.0, have devised the built-in non-slip strip for tread be made up of filler rod and panel.Li Xiangfeng (2005) proposes antiskid glue for stairs (the epoxy resin adhesive containing diamond dust in the invention of CN200510044759.0, can solidify at normal temperatures), do not destroy stairwell surface base material, be applicable to the particular surroundings such as underground or inclined-plane often contacting water.Liu Guanghua (2004) proposes the skid resistant surface using polymer cement mortar as pedestrian overcrossing in " research of Antiskid Materials for Walk Bridge " literary composition.Existing research is mainly for the research of marking time in one-side anti-slip material and ladder access, and the anti-slip version for ramp-type overline bridge but seldom relates to.Therefore, the anti-skidding facility that improves studying ramp-type overline bridge lower slope section has actual using value.
Existing urban ramp-type pedestrian overcrossing can arrange two reinforcement bar walking belt at bridge floor when newly-built, distance between two walking belt is larger, bicycle is caused often to select the centre position of two walking belt when walking, the rubbing action of reinforcement bar does not produce inhibition to bicycle, the speed of bicycle strengthens, otherwise, because reinforcement bar is to the effect of pedestrian, the walking speed of pedestrian significantly reduces, cause both relative velocities larger, bicycle is walked in highdensity pedestrian, all can produce very large harm to pedestrian and the safety of self.On the other hand, due to the existence of reinforcement bar, pedestrian owing to not seeing the concrete condition of bridge floor, may produce the phenomenon of skirt under low-light (level) environment.Except this, also having by arranging staggered annular groove in concrete ramp surface, realizing anti-skidding object, but this kind of method skidproof effect is limited, and after sleety weather, the ponding on domatic is difficult to discharge.Therefore, be necessary to process the laying apparatus of bridge floor, improve the visibility of low-light (level) environment descending route.
