洛湛铁路部分路基软基采用水泥深层搅拌桩进行加固处理,为保证加固质量应进行室内配方试验和成桩试验,在施工中要坚持二喷四搅工艺流程,要把好原材料检验关,确保桩数、桩长、水泥用量及搭接长符合设计要求,并进行随机抽样检验、质量检验等控制环节。 Some sections of Luoyang-Zhanjiang railway subgrade are reinforced with deep cement mixing piles. In order to ensure the quality of reinforcement, indoor formula testing and pile-forming tests should be carried out. During the construction, two sub-four mixing processes should be adhered to. Pile number, pile length, cement dosage and lap length meet the design requirements, and random sampling, quality control and other control aspects.
