Elevator shaft foundation pit construction method
The invention relates to an elevator shaft foundation pit construction method, and relates to the technical field of foundation pit construction, the elevator shaft foundation pit construction method comprises the following construction steps: S1, paying off to define an excavation sideline and a mounting sideline; s2, drilling is conducted, and a grouting pipe is installed; drilling to obtain a plurality of mounting holes, and then inserting a plurality of grouting pipes into the mounting holes; s3, high-pressure concrete pouring is conducted, specifically, the concrete is poured into the grouting pipe at high pressure, and the concrete connects earthworks on the outer sides of the installation side lines together through the through holes for pre-supporting; s4, the earth is excavated to the designed elevation; s5, supporting construction; s6, drainage construction; s7, constructing a cushion layer; s8, protective wall construction; and S9, performing waterproof construction. The earthworks on the outer sides of the mounting sidelines are connected together through the concrete, so that the probability of collapse during earthwork excavation is reduced, and the construction efficiency of the foundation pit is improved.
本申请涉及一种电梯井基坑施工方法，涉及基坑施工的技术领域，包括以下施工步骤：S1、放线定出开挖边线和安装边线；S2、钻孔、安装注浆管；钻孔得到多个安装孔，然后将多个注浆管插入安装孔内；S3、高压灌注混凝土，向注浆管内高压灌入混凝土，混凝土通过通孔将安装边线外侧土方连接在一起进行预支护；S4、土方开挖至设计标高；S5、支护施工；S6、排水施工；S7、垫层施工；S8、保护墙施工；S9、防水施工。本申请通过混凝土将安装边线外侧的土方连接在一起，从而降低了土方开挖时发生垮塌现象的概率，因此提高了基坑的施工效率。
