Asphalt grouting seepage-proofing and leakage-stopping method
The invention provides an asphalt grouting seepage-proofing and leakage-stopping method. The method comprises the following steps: heating asphalt by using an asphalt melting furnace, melting the asphalt for 30-50 min when the temperature reaches a temperature range of 204-260 DEG C to obtain an asphalt solution, adding 50-70% of sand grains with the diameter of 2-5 mm into the asphalt solution, mixing and stirring for 5-10 min to obtain an asphalt mixed solution 1, adding 10-20% of polyurethane into the asphalt mixed solution 1, stirring and mixing for 3-5 min to obtain an asphalt mixed solution 2, adding 5-10% of acrylic acid aqueous emulsion into the asphalt mixed solution 2, stirring and mixing for 2-5 min to obtain an asphalt anti-seepage material, pouring the asphalt anti-seepage material into a high-pressure grouting machine, pouring the asphalt anti-seepage material onto a base layer surface needing anti-seepage by using the high-pressure grouting machine, grinding the asphalt anti-seepage material to be flat by using a mud covering plate, and naturally air-drying for 2-3 days. The method is low in manufacturing cost, simple in process and capable of effectively preventing leakage.
本发明提供了一种沥青灌浆防渗堵漏方法，该沥青灌浆防渗堵漏方法的防渗工艺为，使用沥青熔化炉对沥青进行加热，当温度达到204℃‑260℃的温度区间时，沥青开始熔化，熔炼30min‑50min，得到沥青溶液，将直径大小为：2mm‑5mm、含量为50％‑70％的砂粒添加至沥青溶液中进行混合搅拌，搅拌5min‑10min，得到沥青混合液1，将10％‑20％的聚氨酯添加至沥青混合液1中，搅拌混合3min‑5min，得到沥青混合液2，将5％‑10％的丙烯酸水乳添加至沥青混合液2中，搅拌混合2min‑5min，得到沥青防渗材料，将沥青防渗材料倒入高压灌浆机中，使用高压灌浆机将沥青防渗材料倒在需要防渗的基层面上，使用摸泥板将沥青防渗材料磨平，自然风干2天‑3天。此方法造价低、工艺简单能够有效的防渗漏。
