Abstract
The utility model provides an anti-crack cement road. When the cement road is constructed, a bamboo grid wove by bamboo threads is fixed in the position 3 to 5mm away from the road surface so as to ensure that the cement road obtains the excellent anti-crack capacity.
Description
Technical field
The utility model relates to a kind of cement road, particularly a kind of cement road that can prevent the road surface crackle.
Background technology
Cement pavement since summer, winter and round the clock between the temperature difference, add the impact force of automobile tyre, so be easy to occur crackle, after rainwater pours into crackle, the impact force of high speed wheel drives the sidewall of the fierce bruise of rainwater in the crackle, cause crackle to broaden, and crackle is wide more, rainwater is big more to the impact force of crackle sidewall, thereby forms vicious circle, makes crackle become big crackle, big crackle becomes hollow place, and repair these crackles, and must drop into a large amount of road toll, frequent road surface maintenance engineering usually causes traffic congestion simultaneously.
The utility model content
The purpose of this utility model provides a kind of anti-crackle cement road, to reduce road surface maintenance engineering amount significantly and to prolong application life on road surface.
The purpose of this utility model is achieved in that shortly before the cement road construction works is in the road surface front cover, to be tiled on the roadbed with the wide bamboo net in road surface, the bamboo net is apart from road surface 3～5mm behind the front cover, and the bamboo net forms the cross-sectional area 2～3mm of single bamboo silk by the braiding of bamboo silk
2, the eyelet of bamboo net be shaped as square or rhombus, the area of eyelet is 1～2cm
2, if width of roadway surpasses bamboo net width, then the bamboo net is cut out by several bamboo nets and is combined.
Adopt such scheme can receive following remarkable result:
Though 1, cement intensity height, the hardness after the curing is big, fragility is outstanding, and the bamboo silk has good toughness and tensile strength, but lack compressive strength and hardness, when both are compound is one when whole, then plays the effect of learning from other's strong points to offset one's weaknesses, and the cracking resistance line ability of cement pavement is strengthened significantly.Simultaneously the bamboo net can rottenly not go bad under the protection of cement and sealing, makes cement pavement cracking resistance line ability prolonged constant.
2, the selected of this programme bamboo net relevant parameter can be taken into account necessary toughness, tensile strength and spreadability simultaneously, and to the permeability of cement mortar, it can improve the performance of cement pavement, very is convenient to construction again, and does not influence the planarization on road surface.
3, the bamboo net is fixed near the road surface place, can makes its cracking resistance line ability obtain best performance.
4, the bamboo net materials is easy to get, and cost is extremely low, uses it for cement pavement, can reduce frequency and the corresponding investment of safeguarding construction in the road surface significantly, can prolong service life of road surface significantly again.
Description of drawings
Fig. 1 is the sectional drawing of anti-crackle cement road
1 road surface among the figure, 2 cement mortar, 3 bamboo nets, 4 concrete.
The specific embodiment
When the cement road construction works is in the road surface front cover eve, will be tiled on the roadbed with the wide bamboo net in road surface, the bamboo net is apart from road surface 5mm behind the front cover, and the bamboo net forms the cross-sectional area 3mm of single bamboo silk by the braiding of bamboo silk
2, the eyelet of bamboo net be shaped as square or rhombus, the area of eyelet is 2cm
2, if width of roadway surpasses bamboo net width, then the bamboo net is cut out by several bamboo nets and is combined.
Claims (1)
1, a kind of anti-crackle cement road is characterized in that: under the road surface, the bamboo net is apart from road surface 3～5mm by cement seal for the bamboo net, the cross-sectional area 2～3mm of single bamboo silk
2, the eyelet of bamboo net be shaped as square or rhombus, the area of eyelet is 1～2cm
