Since cement Concrete Pavement arenaceous how to do? Often encountered a lot of road road surface to appear to have arenaceous appearance in us, still have a skin even, dew cobble, the circumstance of hemp face, be in our very much place, basic it is the appearance that achieves to connect, but road surface rises arenaceous also be inevitable, the road surface that although be in,repairs newly also can appear sometimes these phenomena.
Does cement Concrete Pavement rise arenaceous how be handled? Best method is undertaking cement Concrete Pavement rises namely arenaceous before repairing, must undertake investigating an analysis to original road surface, detect, understand the concrete structure of former road surface and performance characteristics, ability revamps plan well certainly
So, does cement Concrete Pavement rise arenaceous commonly those handle program? Usually cent is; of the following plan
1. when after damaged of former road surface is serious, destroy new store to pack new concrete.
2. uses bitumen to repair in the place of disease of former road surface.
3. uses cement Concrete Pavement to repair makings repair
These 3 kinds of plan are current most common repair a method, so we the actor defect that with respect to Henan the expert of Hang Jialu bridge analyses 3 kinds of processing techniques:
Plan 1 destroy new store outfit, affect traffic security badly, and time of conserve of road surface need grows again, and, cost should be gotten high much, change commonly board cost is in 200-300 yuan / ㎡, more expensive, it is to compare a passive kind to repair a method, do not be willing to be done so commonly.
Plan 2 add the cost with average bitumen to be in 50-60 yuan / ㎡, and the structure of the structure of bitumen and concrete is illogical, cause bitumen and cement to stick receive degree of inadequacy, be in especially wet, pass car grind pressure, fall off very easily.
Plan 3 repair with cement Concrete Pavement makings repair opposite for it is current repair a method one kind the most reasonable, construction method is simple, and repair time weak point, cost also is the most reasonable.
Although say, eye comes round to say to be repaired with concrete expecting is the most reasonable revamp plan, although the method is same, but material is different, so, repairing material is the crucial place that cement Concrete Pavement repairs, the quality of material, stick relay to spend, fight press wear-resisting to spend and people cares intensity most, the sexual price that still has stuff of course is compared. Concrete of fine road bridge repairs Henan boat makings, stick by force in order to exceed receive degree, high strenth, fight press wear-resisting to spend advanced advantage, become those who be numerous client quickly to approbate, become the concrete with at present more welcome masses to repair a kind of brand of makings.
Concrete Pavement of cement of Hang Jialu bridge repairs face of makings needle satisfy the need to rise arenaceous repair cent to be; of the following measure
Does 1 road surface clear: ?
2. rinses: Rinse road surface with high-pressured squirt, use pressure to be grabbed in the high-pressured water of 3 above as far as possible, rinse road surface repeatedly and road surface thoroughly wet, it is road surface those who reach a saturation is wet degree.
3. adds water: Mix material and water agitate, the quantity that add water is in fruit of 17% effectiveness for a given period of time is optimal, but differ according to repairing place, to the amount that add water can be being adjusted when dilute spends diverse demand, but control of the capacity that add water is in 15% , 20% between. (2) agitate: The beard when agitate is sufficient mix is even, observation does not have powder ball and bleb, if still have powder ball and bubble, after Ke Jing stops one minute again agitate, it is advisable that agitate time is controlled in 3 minutes, but unfavorable also time is too long, prevent caky inside mix barrel.
4. shop installs: Good agitate repair expect inside the face, use instantly blow feet to drive smooth, ensure the elevation of ground level ground after repairing and elevation of original ground level ground are consistent. Repair makings operation time to should be controlled inside 25 minutes, repair ply 3mm left and right sides.
5. conserve: Repair finish after coagulating one hour first, undertake aspersion instantly and enclothe plastic film to undertake conserve
Anyhow, this method and asphalt path have 4 large dominant positions quite: It is the capital that managing early days repairs, 2 it is layer repairs service life to grow (8, 10 years) , 3 it is road bears the weight of power is high, 4 it is to stick receive degree exceed bitumen far, the save labour when later period conserve is saved, need not repair repeatedly.
