一般要求
1、钢板桩的位置必须符合设计要求，以利于沟槽基础土方施工。也就是说，在地基最突出的边缘之外有用于模板支撑和拆除的空间。
2、基坑沟槽钢板桩的支护平面布置形状应尽可能平直、整齐，避免出现不规则的拐角，以利于标准钢板桩的使用和支护设置。周边尺寸应尽可能与单板模块结合。
3、整个基础施工期间，开挖、吊装、钢筋、混凝土浇筑等施工作业时，严禁碰撞支架、任意拆除支架、在支架上任意切割、焊接，重型设备不得使用。不得放置在支撑物上。事物。
支持线路测量
根据基坑、沟渠开挖设计断面宽度要求，测量并放行钢板桩打桩位置线，并用白石灰对钢板桩打桩位置进行标记。
钢板桩入口及存放区
根据施工进度或现场情况组织钢板桩进场时间，确保钢板桩施工满足预定要求。钢板桩堆放位置根据施工要求和现场情况沿支撑线分散，避免集中堆放在一起造成二次破坏。波蒂奇。
钢板桩施工顺序
定位布置——挖沟——安装导向梁——打入钢板桩——拆除导向梁——檩条及支撑施工——土方开挖——基础施工（输电带）——拆除支撑——地下室主体结构施工——土方回填——钢板桩的拆除——钢板桩拔拔后的间隙处理。
钢板桩的检验、吊装、堆垛
1、钢板桩的检查
对于钢板桩，一般会有材质检验和外观检验，以纠正不合格的钢板桩，减少打桩过程中的困难。
(1)外观检查：包括表面缺陷、长度、宽度、厚度、端部矩形比、直线度及锁形等。注：
A。影响钢板桩打入的焊接部位应予以切除；
b. 切孔和断面缺陷应进行加固；
C。如果钢板桩腐蚀严重，应测量其实际截面厚度。原则上所有钢板桩均应进行外观质量检验。
(2)材料检验：对钢板桩基材的化学成分和力学性能进行全面检测。包括钢材的化学成分分析、构件的拉伸和弯曲试验、锁紧强度试验和伸长率试验等。每个规格的钢板桩至少进行一次拉伸和弯曲试验：每根钢材进行两个试件试验板桩重20-50t。
2、钢板桩吊装
钢板桩装卸宜采用两点吊装法。吊装时，每次吊装钢板桩数量不宜过多，并注意保护锁具，以免损坏。吊装方式有捆绑吊装和单吊装。捆绑吊装通常采用钢丝绳，而单吊装则常采用专用吊具。
3、钢板桩的堆放
钢板桩的堆放地点应选择平坦、坚固、不会因重压而产生较大沉降变形的场地，并应便于运输到打桩施工现场。堆放时应注意：
（1）今后施工应考虑堆放的顺序、位置、方向和平面布局；
（2）钢板桩按型号、规格、长度分别堆放，并在堆放处设置标志牌；
（3）钢板桩应分层堆放，每层桩数一般不超过5根，每层之间应设置枕木。枕木间距一般为3~4m，上下层枕木应在同一垂直线上。堆放总高度不应超过2m。
4、导架安装
在钢板桩施工中，为了保证桩轴位置正确和桩的垂直度，控制打桩精度，防止板桩屈曲变形，提高桩的贯入能力，一般需设置有一定刚度、坚固的导向架，也称“建筑檩条”。
导架采用单层双面形式，通常由导梁和檩条桩组成。檩条桩间距一般为2.5~3.5 m。双面护栏之间的距离不宜过大。一般略大于板桩墙。厚度为8~15毫米。安装导向架时应注意以下几点：
(1)利用经纬仪和水准仪控制和调整导光梁的位置。
(2)导梁高度必须合适，有利于控制钢板桩施工高度，提高施工效率。
(3)导向梁不能随着钢板桩打深而下沉或变形。
(4)导梁位置应尽可能垂直，不应与钢板桩碰撞。
