Submarine pipeline operation pit anti-silting excavation method
The invention relates to the technical field of submarine pipeline operation, in particular to a submarine pipeline operation pit back-silting-preventing excavation construction method which comprises the steps that an excavation area of an operation pit is determined, and stepped excavation is conducted on the excavation area till a deep foundation pit is excavated; and a sand collecting pit is excavated around the deep foundation pit, and excavation of an operation pit is completed. Sediment back silting is slowed down by excavating the operation pits in a stepped mode, sand collecting pits are excavated around the operation pits in the bottom layer to collect back silting sand, the operation time is prolonged, cost is high, and the requirements for the flatness and bearing capacity of a seabed are low.
本发明涉及海底管道作业技术领域，尤其涉及一种海底管道作业坑防回淤开挖工法，包括：确定作业坑的开挖区域，对开挖区域进行阶梯式开挖，直至开挖出深基坑；在深基坑的四周开挖集沙坑，完成作业坑的开挖。通过阶梯式开挖作业坑减缓泥沙回淤，并且在底层作业坑四周开挖集沙坑对回淤泥沙进行聚集，延长作业时间，成本高，对海床的平整度、承载力要求低。
