Larsen steel sheet pile construction method when encountering obstacle in air
The invention relates to a Larsen steel sheet pile construction method when encountering an obstacle in the air. The Larsen steel sheet pile construction method when encountering the obstacle in the air comprises the steps of determining a safe operation range below the obstacle in the air; driving steel sheet piles outside the safe operation range and carrying out inner support; excavating a foundation pit to the set elevation within the safe operation range, and complementarily driving the steel sheet piles; and upwards pulling the steel sheet piles which are complementarily driven, and performing earthwork backfilling to additionally arrange inner supports on the steel sheet piles which are complementarily driven. According to the Larsen steel sheet pile construction method when encountering the obstacle in the air, by adjusting the earthwork excavation mode, the purpose of normally driving the steel sheet piles can be achieved when the steel sheet piles encounter the obstacle in the air during driving, the obstacle in the air does not need to be dismantled, and the construction period can be effectively shortened or material loss can be effectively reduced.
本发明涉及一种碰到空中障碍物时的拉森钢板桩施工方法，包括：确定空中障碍物下方安全作业范围；打设所述安全作业范围外的钢板桩并进行内支撑；安全作业范围内开挖基坑至设定标高并补打钢板桩；上拔补打的钢板桩并回填土方对补打的钢板桩加设内支撑。本发明能通过调整土方开挖方式，在打设钢板桩碰到空中障碍物时，达到正常打设钢板桩的目的，无需对空中障碍物进行拆除，可以有效缩短工期或节约材料损耗。
