Asphalt concrete panel sealing layer repairing method
The invention discloses an asphalt concrete panel sealing layer repairing method and relates to the field of water conservancy and hydropower engineering. The method comprises the following steps that S1, a sealing layer is cleaned, specifically, a grinding machine is adopted for grinding the surface layer of a slope, a winch lifting system is arranged on the dam crest, the grinding machine is dragged to walk on the slope, and a dust removal system is arranged on the grinding machine; s2, emulsified asphalt is sprayed, and a sealing layer is brushed, specifically, a hot blade coating scheme is adopted for brushing of the sealing layer, SK-2 modified asphalt is selected as a material, barrel removal, heating and proper stirring are conducted on site, stirring is conducted after electric heating is adopted, the heating temperature is 190 +/-10 DEG C, and the stirring speed is 15-30 r/min. According to the method, the sealing layer of the dam face of the asphalt concrete face dam is subjected to stripping and blade coating repairing for the first time in China, one-time forming of modified asphalt construction is achieved, the function is improved, meanwhile, a large amount of material cost is saved, aging-resistant SK-2 modified asphalt is selected as a repairing material, and the aging resistance, high temperature resistance and slope flowing capacity of the sealing layer are improved; in the panel cleaning process, vertical grinding is adopted, and pollution to the environment and water quality is avoided.
沥青混凝土面板封闭层修复方法,涉及水利水电工程领域。本发明包括以下步骤:S1封闭层清理:采用打磨机进行边坡表层打磨,在坝顶设置卷扬升降系统,牵引打磨机在斜坡上行走,打磨机上配备除尘系统;S2喷洒乳化沥青及封闭层涂刷:封闭层的涂刷采用热刮涂方案,材料选用SK‑2改性沥青,现场进行脱桶、加热并适当搅拌,采用电加热后进行搅拌,加热温度190°±10°,搅拌速度15‑30r/min。本发明为国内首次对沥青混凝土面板坝坝面封闭层进行剥除、刮涂修复,实现了改性沥青施工一次性成型,提高功能的同时,节约大量材料成本,修复材料选用耐老化的SK‑2改性沥青,提高封闭层抗老化、抗高温以及斜坡流淌的能力;在面板清理过程中,采用竖向打磨,避免污染环境和水质。
