Abrasion-resistant repair grouting material for ballastless track filling layer gap and repair method
The invention discloses an abrasion-resistant and corrosion-resistant repairing grouting material and a repairing method for a ballastless track filling layer gap, and the repairing method comprises the following steps: determining a to-be-repaired position and a to-be-repaired range according to the structural stress and deformation characteristics of a ballastless track, and calculating the use amount of the required grouting material; drilling and dedusting are conducted on the track plate corresponding to the to-be-repaired range; grouting materials are quantitatively injected into the corresponding positions in the filling layer in a targeted mode through a grouting pipe according to the preset grouting speed and the grouting rhythm of grouting-stopping-grouting; and when pause is carried out according to the grouting rhythm, high-pressure air is blown into and sucked out of the filling layer according to the preset rhythm at the preset pressure, the preset direction and the preset air speed along the gap to form a vacuum degree environment with the preset pressure, and the grouting material injected into the filling layer is evenly distributed on the surface of a micropore layer of the filling layer and solidified into a film strengthening layer not larger than 0.5 mm. By means of the technical scheme, the strength and abrasion resistance of the surface layer of the filling layer are improved, and the service performance of the longitudinal connecting plate type ballastless track filling layer is effectively improved.
本发明公开了一种无砟轨道充填层离缝的耐磨蚀修复注浆材料及修复方法，修复方法包括：根据无砟轨道的结构受力与变形特性，确定待修复位置及范围，并计算所需注浆材料的用量；针对待修复范围对应的轨道板进行钻孔并除尘；将注浆材料通过注浆管按照预设注浆速度、注‑停‑注的注浆节奏定量靶向注入充填层中对应位置；按照注浆节奏停顿时，沿离缝以预设压力、方向及风速向充填层中按预设节奏吹入、吸出高压风以形成预设压力的真空度环境，使注入充填层中的注浆材料在充填层的微孔层表面均匀分布并固化为不超过0.5mm的薄膜强化层。通过本发明的技术方案，提高了充填层表层的强度和耐磨性，有效提升了纵连板式无砟轨道充填层的服役性能。
