  一,钢板桩加工
  1. Steel sheet pile processing
  堆放之前的钢板桩通常按以下步骤处理:(1)夹钳护板的处理。 在钢板桩的外侧增加了焊接保护板,以避免钢板桩剧烈振动而引起的桩头撕裂。  (2)在桩头下方适当的位置开孔,以抬起桩。  (3)拉直桩身并加强焊接板,以防止钢板桩在下沉过程中向外伸出。 加强板应尽可能放置在没有防腐涂层的区域。  (4)在桩上标出刻度,以跟踪钢板桩的桩深。
  Before stacking, steel sheet piles are usually handled in the following steps: (1) the treatment of clamp guard plates. Welded protective plates are added to the outside of steel sheet piles to avoid tearing of pile head caused by violent vibration of steel sheet piles. (2) Open holes at appropriate positions below the pile head to lift the pile. (3) Straighten the pile body and strengthen the welding plate to prevent the steel sheet pile from extending outwards during the sinking process. The reinforcing plate should be placed in the area without anticorrosion coating as far as possible. (4) Mark the scale on the pile to track the pile depth of steel sheet pile.
  二,导向架的安装
  2. Installation of guide frame
  在引导框架被吊起和定位之后,通常需要在引导框架的两侧上设置支撑桩或其他支撑结构以稳定引导框架。 可以根据需要设置导向框架中桩体两侧的极限。 通常,起始极限仅在起始桩的位置使用,随后的桩可以以前桩作为起始终点极限来弯曲。
  After the guiding frame is hoisted and positioned, it is usually necessary to install supporting piles or other supporting structures on both sides of the guiding frame to stabilize the guiding frame. The limit of both sides of the pile in the guide frame can be set according to the need. Usually, the initial limit is used only in the position of the initial pile, and the subsequent pile can be bent with the former pile as the initial end limit.

  三,钢板桩设计
  3. Design of steel sheet piles
  沉桩法可以采用一体式或筛网式的打法,板桩墙的桩一般进行分组。 在下沉桩的过程中,导向架的高度受到限制。 前一组板桩通常下沉至导向架上方约1 m,而后一组钢板板桩的第二个钢板桩则位于导向架上导向梁下方50 cm。 安装导向架,将组的后一个钢板桩用作组桩壁的起始桩,并依次完成组桩壁。 依此类推,直到完成所有的钢板桩桩。
  Pile driving method can adopt one-in-one or screen driving method, and sheet-pile wall piles are generally grouped. In the process of pile sinking, the height of the guide frame is limited. The former group of sheet piles usually sinks about 1 m above the guide frame, while the second group of sheet piles of the last group is located 50 cm below the guide beam on the guide frame. The guide frame is installed, and the last steel sheet pile of the first group is used as the starting pile of the first group of pile walls, and the first group of pile walls are completed in turn. By analogy, until all steel sheet piles are completed.
  无导向框架的构造省去了导向框架的生产和安装,并且相应地减少了工作时间和设备。 施工简单,其他过程基本相同,主要是桩深,极限位置和一次性桩。 有一定的区别。
  The construction of the non-guided frame eliminates the production and installation of the guided frame, and reduces the working time and equipment accordingly. The construction is simple and the other processes are basically the same, mainly pile depth, limit position and disposable pile. There are some differences.
  (1)桩上作业。 由于拆下导架后没有打桩工作平台,打桩过程比较麻烦,可以将锁扣切开5cm以利于钢板桩的对接。
  (1) Pile operation. Because there is no working platform for piling after removing the guide frame, the piling process is more troublesome. The lock can be cut 5 cm to facilitate the docking of steel sheet piles.
  (2)桩极限。 在安装过程中,没有导架支撑支撑结构,可以使用挖掘机辅助施工。 将限位板焊接到铲斗上,以防止钢板桩掉落。
  (2) Pile limit. In the process of installation, there is no support structure of guide frame, so excavator can be used to assist construction. Weld the limit plate to the bucket to prevent the steel sheet pile from falling off.
  (3)一次沉没深度。 不带导向架的单桩结构不应太低。 随后的钢板桩至少应保留重叠长度的1/5,以防止桩桩掉落以及桩桩因变形而引起的变形。 主要使用逐根方法。
  (3) Depth of sinking once. The single pile structure without guide frame should not be too low. Subsequent steel sheet piles should retain at least one fifth of the overlap length to prevent pile dropping and pile deformation caused by deformation. The root-by-root method is mainly used.
