鲍店北风井表土层冻结段掘砌,采用五层吊盘、拉杆式液压滑模及25吨双凿井绞车等新工艺,新设施,实现了竖井冻结段掘砌平行作业施工,创月成井167.54米平行作业的全国纪录。共节约木材85米~3、钢材15吨、资金21.67万元。提高了劳动效率,掘进工效达1.46米~3/工(定额为0.8米~3/工)、砌筑工效为1.23米~3/工(定额为0.8米~3/工)。本井的平行作业是以五层凿井吊盘和液压滑模筑壁的工艺方式为核心的,现摘要予以介绍。
Baodian north wind surface soil freezing section excavation, the use of five hanging plate, pull rod hydraulic sliding mode and 25 tons of double sinking winch and other new technologies and new facilities to achieve the parallel operation of the shaft freezing section digging construction, create a month 167.54 meters into the well parallel to the national record. A total of 85 meters to save timber 3, steel 15 tons, 216,600 yuan of funds. Improve labor efficiency, excavation efficiency of 1.46 m ~ 3 / workers (quota of 0.8 m ~ 3 / workers), masonry work efficiency of 1.23 m ~ 3 / workers (quota of 0.8 m ~ 3 / workers). Parallel operation of the well is based on the five-layer shaft sinking and hydraulic sliding mode wall construction technology, the summary will be introduced.
