第一章 人工挖孔桩 第一节 人工挖孔桩开挖示意图

说明：

1、孔桩开挖过程中，必须有专人巡视各开挖桩孔的施工情

况，，严格做好安全监护。

2、挖孔、起吊、护壁、余渣运输等所使用的一切设备、设

施、安全装置（含防毒面具）、工具、配件、材料和个人 防护用品等，必须经常检查，做好管、用、养、修、换， 确保完好率和使用安全度。

3、当桩径小于（或等于）1.2米时，每次下孔作业前必须 先通风，作业过程中必须保持继续通风。

4、开挖过程中，必须及时施作护壁，第一节护壁应高出孔 口不小于25厘米。

5、挖出的土石方应及时运走，孔口周边2米范围内不得堆 放孔渣及杂物，机动车辆通行时，应做出预防措施或暂 停孔内作业。

6、当桩孔开挖深度超过5米，每天开工前应进行有毒气体检测；遇到不良地质时，应采取相应措施以防塌孔。

第二章 泥浆池

第一节 泥浆池平面布置示意图

说明：

1、本图尺寸仅为示意，泥浆池的平面尺寸及容量应根据工程需要确定。 2、泥浆池基础需设置在稳定的地质上，如在城市施工，则应将泥浆池底部硬化并采取措施防止泥浆外溢。

3、在循环池和沉淀池中间隔墙上设空洞以连通两池。

第二节

泥浆池临边防护

说明：

1、泥浆开挖后立既进行防护，泥浆池采用钢管或竹杆沿泥 浆池四周布置安全防护围网，围网高度1.2米左右，要求所

有泥浆池防护网高度一致。

2、竹杆外面采用蓝色的细网围裹，上面围设小彩条旗，外 挂安全标志牌。 3、钻孔时，钻孔循环泥浆必须在钻孔平台上挖出排放沟，

沟深0.3米左右，沟宽0.3米左右，在灌注前，因排浆量较 大，必须加深或沟侧堆码一定的高度约30厘米高；在不使

用时，将沟填平，必要时可以在钻孔下根桩基循环利用。 4、所有钻机的泥浆管当有损坏时，必须进行修整或更换新 管，保证在施工时泥浆不从损坏处漏出，倒处排放。

5、泥浆池中的泥浆装满后用泥浆车拉运出去，在抽浆时， 泥浆车停放位置处不得出现漏浆现象。

第二节 水上作业平台的安全防护

说明：

1、平台四周设置防护栏杆，栏杆高1.2米，钢管立柱间距2.0米；

横杆间距0.5米，护栏外挂密目安全网。

2、平台上的电气设备必须使用“三相五线制”和“三级配电两级

保护” 电线（缆）必须按要求架设，不得随地拖拉，各类配电箱 要安装在适当的位置，并进行防护。

3、为防止过往船只及施工船只撞击施工平台，平台首尾须设置航

标灯、信号旗及防撞装置。另外，要密切观测平台处钢管桩的冲刷 情况，必要时进行二次抛石防护。

4、为确保平台和施工人员的安全，每时每刻注意与气象部门的气

象信息，如遇大风、台风等恶劣天气和海况，严禁作业。

第五章 桥梁通道 第一节 桥梁通道示意图

说明：

1、 本图仅为示意，应根据工程的实际受力情况进行通道结构设计。

2、 通道两侧应设置限高、限宽及限速标志。

3、 通道两侧须设置防撞墙，以免过往

车辆碰撞支架体系。

4、 通道两侧及顶部应设置至少3道安

全防护网，以免高空坠物伤及行人及过往车辆。
