Construction method for excavating earth below existing pipeline
The invention relates to the field of civil engineering construction, in particular to a construction method for excavating earth below an existing pipeline, which comprises the following steps: S1, constructing a support pile; s2, earth excavation is conducted; s3, setting an instant supporting device; and S4, the muck is transported outwards, and construction is completed. Construction is guided through the four steps of S1, S2, S3 and S4, so that the intersection of an existing pipeline and a new pipeline can be effectively supported and protected, and earthwork collapse and extrusion to the pipeline are effectively prevented; meanwhile, the mode that the pile driver and the excavator are combined is adopted, the construction efficiency is high, excavation of the foundation pit can be rapidly completed, and the construction period is shortened. The method has the effect that the problems that vibration and sedimentation of soil around an original pipeline are possibly caused by construction of a newly-added pipeline or a structure, the original pipeline is interfered and influenced, and the stability and safety of the pipeline are influenced are solved to a certain extent.
本申请涉及土木工程施工领域，尤其是涉及一种既有管线下方土方开挖施工方法，包括S1、支护桩施工；S2、土方开挖；S3、即时支护装置设置；S4、外运渣土，完成施工。通过S1、S2、S3、S4这四个步骤进行指导施工，使得在既有管线与新管线交汇处能够被有效地支撑保护，有效防止土方坍塌和对管线的挤压；同时，采用打桩机和挖掘机相结合的方式，施工效率高，能够快速完成基坑的开挖，减少施工周期。本申请具有一定程度上解决了新增管线或构筑物的施工可能会引起原有管线周围土壤的振动和沉降，对原有管线造成干扰和影响，影响管线的稳定性和安全性的问题的效果。
