Rapid leveling construction method for soft rock foundation or hard soil foundation
The invention discloses a rapid leveling construction method for a soft rock foundation or a hard soil foundation. A protective layer higher than a designed base plane is reserved, and bottom picking and leveling are conducted in a milling mode through a milling machine; comprising the following process steps: reserving a protective layer; acquiring milling construction parameters; selecting a milling parameter combination with the lowest comprehensive index value as construction parameters; milling by a milling machine; according to the construction method, a milling method is adopted for bottom picking and leveling, the flatness deviation of a forming face can be reduced layer by layer through multi-layer milling, the flatness deviation is controlled at the mm level, and base over-excavation is effectively controlled; compared with the prior art, the construction method has the advantages that the foundation surface is slightly disturbed, the foundation surface can be protected, overexcavation and backfilling are reduced, the construction method is high in mechanization degree and high in leveling speed, investment is reduced, meanwhile, the relation between construction efficiency and foundation surface forming is effectively balanced, and the problems of disintegration, softening and the like caused by long-time exposure of the foundation surface in the soft rock bottom picking process are solved.
本发明公开了一种软质岩地基或坚土地基快速整平施工方法。采用预留高于设计基面的保护层，通过铣刨机械铣刨方式捡底整平；包括以下工艺步骤：预留保护层，铣刨施工参数获取，选择综合指数值最低的铣刨参数组合作为施工参数，铣刨机铣刨，路面清扫和扫除杂物。本发明施工方法采用铣刨法捡底整平，通过多层铣刨可逐层减小成型面的平整度偏差，整度偏差控制在mm级，基底超挖得到有效控制；对建基面的扰动较小，有利于保护建基面，减少了超挖和回填，本发明施工方法机械化程度高、整平速度快，减少投入的同时，有效平衡施工效率和建基面成型的关系，避免软质岩捡底过程中建基面长时间暴露造成的崩解软化等问题。
