摘　　要：某管网工程,根据区域性地质资料和周边场地地勘报告,结合工程特点,10 m之内的地层自上而下分布的主要地层有:素填土、粉质黏土、粉细砂,但现场在实际做沉井过程中在地下3 m左右位置都发现有块石回填和大孤石情况,需人工清障后才能进行顶管施工,以保证施工目标的顺利实现,为后期人工清障积累施工经验,提供示范效应。According to regional geological data and surrounding site geological survey reports,the main strata distributed from top to bottom within 10 meters of a certain pipeline network project are:plain fill,silty clay,and fine sand.However,during the actual process of sinking the well on site,it was found that there were rock blocks backfilled and large isolated stones about 3 meters underground.It is necessary to manually clear the obstacles before carrying out the pipe jacking construction to ensure the smooth achievement of the construction goals.This article provides a demonstration effect for accumulating construction experience in manual obstacle clearance in the later stage.
