Municipal comprehensive pipe gallery excavation and earthwork transfer method
The invention discloses a municipal comprehensive pipe gallery excavation and earthwork transfer method. The method comprises the following steps: S1, early-stage preparation: geological exploration-risk assessment-engineering design; s2, a construction site is arranged; s3, first-stage excavation is carried out; s4, second-stage excavation is carried out; s5, excavation at the third stage; s6, earth and stone treatment is conducted, specifically, a four-step slope relief excavation method is adopted, and the four-step slope relief excavation method is innovatively applied to pipe gallery earth excavation construction; the comprehensive pipe gallery excavation and earthwork transfer method is reasonable in design, on the basis of continuous construction operation, it is guaranteed that the construction procedure connection is compact, the excavation period is shortest, disturbance to surrounding pipelines and structures is small, and the earthwork transfer efficiency is high, meanwhile, an operation platform for steel support installation personnel is reserved under the undisturbed foundation pit condition, and the construction efficiency is improved. And an up-and-down channel of equipment operators in the foundation pit is provided, and the cost is relatively low.
本发明公开了一种市政综合管廊开挖及土方转运方法，包括以下步骤：S1、前期准备：地质勘探‑风险评估‑工程设计；S2、布置施工现场；S3、第一阶段开挖；S4、第二阶段开挖；S5、第三阶段开挖；S6、土石方处理：采用四台阶退坡开挖法，将其创新性地应用于管廊土方开挖施工中；该政综合管廊开挖及土方转运方法设计合理，在连续施工作业的基础上，保证施工工序衔接紧凑，开挖周期最短，对周边管线及构筑物的扰动小，土方转运效率高，同时利用原状基坑条件留置钢支撑安装人员的操作平台，以及基坑内设备操作人员的上下通道，成本相对较低。
