Construction method for newly-added entrance and exit and elevator shaft of existing building
The invention provides a construction method for a newly-added entrance and exit and an elevator shaft of an existing building. The construction method is characterized by comprising the following steps that S1, steel sheet piles are inserted and driven, specifically, measuring and paying-off are conducted outside original supporting piles at the positions of the newly-added entrance and exit and the elevator shaft, the mounting positions of the steel sheet piles are released, the steel sheet piles are driven through a pile driver, an independent driving method is adopted for inserting and driving of the steel sheet piles, and the steel sheet piles are continuously driven one by one; S2, steel pipe supports are erected, specifically, the multiple steel pipe supports are erected on the two sides of the newly-added elevator shaft to be used for supporting the steel sheet piles, one ends of the steel pipe supports are arranged on the steel sheet piles, and the other ends of the steel pipe supports are arranged on an original structure of the existing building; S3, the original supporting piles are chiseled away, specifically, the original supporting piles on the inner sides of the steel sheet piles are chiseled away to the newly-added entrance and exit and the bottom of an elevator shaft platform, and the positions are backfilled to the bottom of the platform in situ through a lower chamber fertilizer groove; S4, the newly-added entrance and exit and an elevator shaft main body structure are constructed; and S5, the steel pipe supports are dismounted, and the steel sheet piles are pulled out.
一种既有建筑新增出入口及电梯井的施工方法，其特征在于，包括以下步骤：S1、插打钢板桩：在新增出入口及电梯井位置处原支护桩外进行测量放线，放出钢板桩的安装位置，利用打桩机打入钢板桩，钢板桩插打采用单独打入法，钢板桩单桩逐根连续施打；S2、架设钢管支撑：在新增电梯井的两侧架设多根钢管支撑用于支撑钢板桩，所述钢管支撑一段设置在钢板桩上，另一端设置在既有建筑原结构上；S3、原支护桩凿除：将钢板桩内侧原支护桩凿除到新增出入口及电梯井平台底部，并将该位置原地下室肥槽回填至平台底部；S4、新增出入口及电梯井主体结构施工；S5、钢管支撑拆除以及钢板桩拔除。
