Pipe gallery construction method with solidification before excavation
The invention discloses a pipe gallery construction method with solidification before excavation, and particularly relates to a pipe gallery construction method that does not need to perform supporting excavation in soft soil areas. The pipe gallery construction method mainly includes the following steps of solidification agent ratio design, site treatment, in-situ solidification treatment, pipe gallery excavation, pipe gallery construction and solidified soil backfill. The pipe gallery construction method is used to solidify soft soil mass within an excavation range of a pipe gallery to formsolidified soil with a certain self-supporting ability, the pipe gallery is excavated in the solidified soil, the soil mass on the two sides can resist the soil pressure generated by the excavation, and the safety of a project can be ensured. The excavated soil mass can further be used as backfill for the upper part of the pipe gallery after resource utilization, and can further provide high-quality filling for other road projects. According to the pipe gallery construction method, the driving of supporting piles can be avoided, the waste soil mass is subjected to resource utilization, the economic benefits are higher, and the method is more conducive to environmental protection.
本发明公开了一种先固化后开挖的管廊施工方法，特别涉及一种在软土地区无需进行支护开挖的管廊施工方法，主要包括以下步骤：固化剂配比设计、场地处理、原位固化处理、管廊开挖、管廊施工、固化土回填。使用该方法将管廊开挖范围内的软弱土体固化形成具有一定自立能力的固化土，在固化土中开挖管廊，两侧土体能够抵抗开挖产生的土压力，能够保证工程安全。挖出土体经过资源化利用后亦可作为管廊上部回填料进行使用，也可为其他道路工程提供优质填料。该方法能够避免支护桩的打设，将废弃土体进行资源化利用，经济效益更高，更有利于环境保护。
