津秦客专水泥乳化沥青砂浆施工及质量控制技术

Construction and Quality Control of Cement-emulsified Asphalt Mortar in Jinqin Passenger Railway

以津秦客专CRTSⅡ型板式无砟轨道水泥乳化沥青砂浆的工程实践经验为基础,总结了水泥乳化沥青砂浆的质量标准、施工及质量控制技术,尤其通过对板腔润湿、砂浆状态控制、砂浆配合比调整、灌注工艺等关键工序工艺的固化与控制以及对灌注、封边、泵送等相关重要工艺工器具的创新与改进,有效解决了水泥乳化沥青砂浆施工中易出现的浮浆、夹层等质量问题,进一步推进了无砟轨道的规范化、标准化施工,确保了津秦客专水泥乳化沥青砂浆的施工质量。

Based on the practical experience from the construction of cement emulsified asphalt mortar for the ballastless track of Jinqin Passenger Railway,quality standards,construction methods and construction quality controlling techniques were summarized.By fixing the key processes of wetting,mortar state controlling,mortar ratio adjusting and grouting and improving the key construction tools used in grouting,sealing and pumping,the quality problems such as floating pulp,mezzanine,etc.were effectively solved.This work helps the normalization and standardization for the construction of ballastless tracks and ensured the construction quality of cement emulsified asphalt mortar in Jinqin Passenger Railway.
