The invention provides a mounting method for a top-down method deep foundation pit construction elevator. The mounting method comprises the steps of (1) elevator foundation pile foundation construction and elevator mounting preparation work; (2) mounting of a guiding track bracket of an elevator; (3) mounting of a wall-attached frame; (4) normal mounting of the elevator; and (5) complete machine debugging and testing, inspection and acceptance. The construction principle of 'one column for one pile' is utilized, the guiding track bracket is overall inserted into a lower pile foundation of a bottom plate in an assembled mode, an empty pile is backfilled with a water stabilized material in time, a vertical bearing system is constructed in advance, along with layer-by-layer downward excavation of top-down earthwork, the construction elevator sinks layer by layer, adhering reverse movement is additionally set layer by layer, and thus the problem of top-down method deep foundation pit mounting of the construction elevator is solved.
逆作法深基坑施工电梯安装方法,包括以下步骤:(1)电梯基础桩基施工和电梯安装准备工作;(2)电梯导轨架安装;(3)附墙架安装;(4)电梯正常安装;(5)整机调试及试验、检查验收。本发明利用“一柱一桩”施工原理,将导轨架整体拼装插入底板下桩基,空桩部位采用水稳料及时回填,竖向承载体系先期施工,随着逆作土石方逐层往下开挖,施工电梯逐层下沉,逐层加设附着的反向运动,从而解决了逆作法深基坑安装施工电梯的难题。
