Abstract
The invention discloses a construction process of a surface layer blind sidewalk of a cement concrete sidewalk. The construction process includes the steps of surveying and setting-out, pavement dust removing, filling manufacturing, mould plate laying, charging and shaping and demoulding. Epoxy resin, a curing agent and natural colored sand in a specific proportion are adopted and directly shaped on the surface of the cement concrete sidewalk through a special blind sidewalk mould plate, and the product can be put into use after a short time of curing; the construction process has the advantages that the process is simple, and construction is convenient. The blind sidewalk constructed through the construction process and the cement concrete pavement are combined into a whole, and the blind sidewalk has the advantages of being high in weather resistance and strength, good in wear resistance, long in service life and low in laying cost.
Description
Technical field
The present invention relates to road traffic facility technology field, particularly a kind of construction technology of sidewalk for visually impaired people.
Background technology
Sidewalk for visually impaired people is the road equipment helping blind person to walk specially, is usually laid on downtown area road, square, pedestrian street, shopping street, bridge, tunnel, graded crossing and notes on the sidewalk in building location.Sidewalk for visually impaired people is generally just spread by two class bricks, and a class is that bar shaped guides brick, guides that blind person is relieved moves ahead, and is called sidewalk for visually impaired people of advancing; One class is the prompting brick with round dot, and the space environment of prompting blind person route ahead is about to change, and is called prompting sidewalk for visually impaired people.
Along with GB 50763-2012 " barrier free design specification " popularization with enforce, some cement concrete sidewalks not laying sidewalk for visually impaired people at the beginning of building start to carry out mending the work of establishing sidewalk for visually impaired people.But be the road surface that main material does surface layer because current sidewalk is with cement concrete, have the advantages that hardness is high, rigidity is strong, for the cement concrete sidewalk built up, the techniques such as road pavement fluting, punching can only be relied on to complete the laying of sidewalk for visually impaired people, very big to the destructiveness of sidewalk.
Outdoor sidewalk for visually impaired people product in the market has sidewalk for visually impaired people section bar and the blind road plate of precast concrete blind way brick, plastics or metal material.
When adopting precast concrete blind way brick to lay sidewalk for visually impaired people, the construction technology of employing is: on road surface, cement concrete sidewalk, use special fluting apparatus, excavates a groove suitable with blind way brick size, is then routed in groove by blind way brick; The enforcement of this kind of technique, can cause larger injury to sidewalk, digs the time-consuming effort of cutter groove, long construction period simultaneously, with high costs.
When adopting sidewalk for visually impaired people section bar, blind road plate to lay sidewalk for visually impaired people, because sidewalk for visually impaired people section bar and blind road plate adopt the material such as rubber plastic or non-ferrous metal to make, there is one to three spike projection section bar bottom surface, need before laying to draw on road surface, cement concrete sidewalk to lay position line, hole on road surface according to the quantity of spike projection and position, and thoroughly remove the dust that boring produces, then at the surface smear bonding agent of the bottom surface of sidewalk for visually impaired people section bar and spike projection, be bonded on road surface.This technique road pavement has damage, complex operation, and efficiency comparison is low, and have loosening after some time of use, firmness is poor.Also there is inevitably malice pilferage problem in the sidewalk for visually impaired people section bar for metal material.For the sidewalk for visually impaired people section bar of plastics, quality of rubber materials, the situation that can produce material aging, come off along with solar radiation.
Summary of the invention
The technical issues that need to address of the present invention are to provide a kind of without the need to destroying sidewalk road surface, and construct simple and convenient, with low cost, firmness is higher, the sidewalk for visually impaired people construction technology of long service life.
