Background technology
At present, the road kerb of road both sides generally is to adopt ordinary concrete prefabricated.Ordinary concrete is at sunshine, temperature, carbon dioxide, drying and watering cycle, alternating stresses, and the comprehensive function of inside and outside factor of cracking such as deicer salts erosion damages deterioration down easily, and particularly under the collision and scraping effect of vehicle, the part sustains damage easily; The ordinary concrete road kerb also owing to each other reasons such as collision, causes truncation arrisdefect etc. to damage phenomenon in making, transportation and installation process easily.These damage phenomenon not only influences the attractive in appearance of road, but also has reduced the functional performance and the endurance quality of road kerb.Therefore, the ordinary concrete road kerb generally needs regular maintenance, even changes, and has increased its maintenance costs greatly.Simultaneously, also there is the heavy and higher shortcoming of construction cost of quality in existing ordinary concrete road kerb.
Summary of the invention
For addressing the above problem, the utility model proposes a kind of new concrete material road kerb, it is that a kind of novel active powder concrete material of high-strength, high-durability that adopts replaces the road kerb of ordinary concrete material, and has specific shape.Adopt road kerb of the present utility model can effectively improve the endurance quality and the anti-scratch collision ability of road kerb, thereby increase the service life, reduce the maintenance cost, guarantee the attractive in appearance of road.Because its weight only is half of ordinary concrete road kerb weight, also can reduce construction cost simultaneously.
For achieving the above object, the utility model adopts following technical scheme:
A kind of RPC road kerb, described road kerb is one integral prefabricated, constitute by top board 1, end rib plate 2, side panel 3 and base plate 4, described top board 1 is arranged on the road kerb top, described end rib plate 2 is arranged at the end, the left and right sides of road kerb, and be provided with 2 circular holes 5 from top to bottom, base plate 4 is arranged at the road kerb bottom, and top board 1, end rib plate 2, side panel 3 and base plate 4 surround a trench structure.
Described road kerb is installed in the marginal strip of road both sides.
Vertically adjacent road kerb is connected and fixed at end rib plate place by 2 bolts, and bolt is arranged in the circular hole 5.Simultaneously, also be bonded together between adjacent road kerb by the jointing mortar.Other job practices is with the job practices of ordinary concrete road kerb.
The above-mentioned diameter of bolt that is used to connect is 20mm.
The material of described road kerb is a kind of RPC material of high-durability.The raw material of RPC are Portland cement, SiO
2Content is not less than 90% silicon ash, I level flyash, coarse sand, medium sand, high-efficiency water-reducing agent of poly-carboxylic acid and drinking water, and quality mixture ratio is: cement: silicon ash: coarse sand: medium sand: high efficiency water reducing agent: water=1: 0.25: 0.17: 1.14: 0.02: 0.25.
The RPC preparation methods is: 1. by the various raw material of match ratio requirement weighing; 2. coarse sand, medium sand are added mixer, dried stirring to evenly; 3. add that cement, silica flour and flyash are dried to be stirred to evenly; 4. water and high efficiency water reducing agent are mixed, add mixer, mix thoroughly and get final product.
Above-mentioned RPC road kerb manufacture craft is: 1. mounting template; 2. with the inboard brushing release agent of template; 3. in template, build the RPC for preparing; 4. the moulding of on vibroplatform, vibrating; 5. put into mark and support chamber maintenance 24 hours, form removal then; 6. put into 80 ℃ steam-cured 72 hours of stream curing environment.After steam-cured the finishing, then the RPC road kerb is made and is finished.
The beneficial effects of the utility model are: the novel active powder concrete material that the utility model adopts has advantages such as superhigh intensity, high tenacity, high-durability, high-wearing feature, high impact properties.The RPC road kerb utilizes the superhigh intensity of this kind material, can reduce the volume and the deadweight of road kerb, is easy to transportation and construction, reduces construction cost; Utilize the high-durability of this kind material, can reduce of the erosion of adverse circumstances such as deicer salts road kerb; Utilize the high-wearing feature of this kind material, can prevent the phenomenons such as truncation arrisdefect in the work progress, and can weaken vehicle, thereby increase the service life, reduce the maintenance expense, can guarantee aesthetic simultaneously the road kerb collsion damage of swiping.Affiliated road kerb is applicable to the road kerb of road both sides.
