人工挖孔桩专项施工方案

人工挖孔桩专项施工方案

一、工程概况

该项目位于某市区域内，建设单位计划建设一幢高层建筑地上40层，地下室3层的建筑。基础采用桩基础形式，其中地下室采用人工挖孔桩。本方案主要对人工挖孔桩专项施工进行说明。

二、技术方案

1.挖孔前的准备工作

1.1确定孔位置和孔径

根据设计要求，确定孔的位置和孔径。在孔洞的两侧打马脚线，并严格按照设计要求进行搭设，确保孔的安全施工和效果。

1.2材料准备

挖孔所需用到的器具、材料以及机械设备等需要进行准备。

1.3检查地下管线

在挖孔前，需要进行地下管线检查，确保挖孔过程中不会影响到已有的各类管道。如有影响到管道，需要及时进行管道搬迁。

2.挖孔操作

2.1挖孔

在准备工作完成之后，开始进行挖孔操作。根据设计要求，在孔洞两侧分别打开孔道，依次进行挖掘和疏通操作，直到挖完孔的深度和直径。

2.2清理孔壁

挖孔深度达到一定程度后，需要进行孔壁的清理工作。清理孔壁时，要确保不影响孔的直径和深度。清理完毕后，应将孔口清理干净，确保孔内无泥土。

2.3测量孔深孔径

在挖掘完成后，需要对孔深和孔径进行测量。以确保其符合设计要求。如有不符合要求的，需要及时进行修正处理。

2.4放置钢筋骨架

在挖孔完成后，需要进行放置钢筋骨架的工作。钢筋骨架应该设置在孔洞内，竖向直到孔底，横向应穿过孔洞的两端和中间。

2.5施工方案审核

在挖孔后，应将施工方案进行审核。审核内容包括孔深的控制、钢筋骨架的加固、孔壁的支护等。

3.加固与支护

3.1分层加固

进行分层加固时，需要根据孔的直径和深度，分别将混凝土依次浇入孔内，防止孔内土体坍塌。同时，在浇筑时需要注意控制混凝土的流动，确保其充满整个孔壁。

3.2钢套管加固

钢套管加固适用于较深的孔洞，其主要作用是增加孔洞的稳定性和承载能力。加固材料主要采用钢材和混凝土。在混凝土浇筑的同时需要将钢管套入孔内，钢管的直径一般比孔洞直径略小。

3、编制专项施工方案，开挖深度为16米及以上，属于一定规模，危险性较大的分项工程，需组织专家论证。

四、评审报批后，对项目交底。

（二）材料准备

钢筋、模板、木枋、钢筋、混凝土等材料需用计划，并按计划进场。

（三）现场准备

1、工程竣工前场地的“三通一平”工程完成，地下管线、地面废弃建筑等全部拆除完毕，临水、临电已接驳到位，满足施工需求。

2、结合拟采用的设备型号参数，在场内修建临时施工道路，满足大型机械设备和物资运输车辆通行。

3、在现场进行场地交接。

4、计划好护壁、水泥、沙、石子、钢筋等堆放场、加工场地，并做好护壁混凝土配合比。
