摘　　要：沉井在强透水的砂层和砂夹卵石等地层中下沉时,采用普通的不排水下沉工法施工时功效较低,而采用自制的空气吸泥器下沉装置,通入高压空气吸渣,并配备潜水员水下作业,促使沉井快速下沉。when strongly permeable sand and gravel layer in sand clip sinking and use common unsinking methods,it is ineffective.However,it is use homemade air sucking sinking device and suct slag by ventilation with high pressure air and work by diver underwater can open caisson fast to sink.
