  Development history of steel sheet pile, advantages and functions of steel sheet pile
  钢板桩的介绍
  Introduction of steel sheet pile
  钢板桩于20世纪初在欧洲开始生产,1903年,日本通过进口在三井本馆的挡土施工中采用,基于钢板桩特殊的使用性能,1923年,日本在关东大震灾修复工程中大量进口采用。20世纪50年代,我国在铁路桥梁围堰施工中,由铁道部大桥局从原苏联引进使用。随着我国经济的快速发展,钢板桩挡墙作为一种快捷、、环保的建筑工法得以认可并发展。
  Steel sheet piles were produced in Europe at the beginning of the 20th century. In 1903, Japan imported steel sheet piles for the first time to be used in the retaining construction of Mitsui Museum. Based on the special use performance of steel sheet piles, Japan imported a large number of steel sheet piles in the restoration project of the great earthquake in Kanto in 1923. In the 1950s, the construction of railway bridge cofferdams was first introduced from the former Soviet Union by the bridge bureau of the Ministry of railways. With the rapid development of China's economy, steel sheet pile retaining wall as a fast, efficient and environmental protection construction method has been recognized and developed.

  1. High quality (high strength, light weight, good water resistance)
  2. 施工简单,工期缩短
  2. Simple construction and short construction period
  3. 耐久性良好,寿命20—50年
  3. Good durability, 20-50 years service life
  4. 建设费用便宜
  4. Low construction cost
  5. 互换性良好,可重复使用3—5次
  5. Good interchangeability, reusable for 3-5 times
  6. 施工具有显著的环保效果,大量减少了取土量和混凝土的 使用量,有效地保护了土地资源 7. 救灾抢险的时效性较强,如防洪、塌方、塌陷、流沙等
  6. The construction has significant environmental protection effect, greatly reducing the amount of soil and concrete used, effectively protecting the land resources 7. The timeliness of disaster relief is strong, such as flood control, collapse, collapse, quicksand, etc

  钢板桩支护
  Steel sheet pile support
  当基坑较深、地下水位较高且未施工降水时,采用板桩作为支护结构,既可挡土、防水,还可防止流砂的发生。板桩支撑可分为无锚板桩(悬臂式板桩)和有锚板桩。常用的钢板桩为U型钢板桩,又称拉森钢板桩。
  When the foundation pit is deep, the underground water level is high and no construction dewatering is carried out, sheet pile is used as the support structure, which can not only retain soil and water, but also prevent the occurrence of quicksand. Sheet pile support can be divided into non anchored sheet pile (cantilever sheet pile) and anchored sheet pile. The commonly used steel sheet pile is U-shaped steel sheet pile, also known as Larsen steel sheet pile.

  板桩施工要正确选择打桩方法、打桩机械和流水段划分,以保证打设后的板桩墙有足够的刚度和防水作用。
  During sheet pile construction, piling method, piling machinery and flow section division shall be correctly selected to ensure that the sheet pile wall after driving has sufficient rigidity and waterproof function.
  打桩方法的选择
  Selection of driving method
  钢板桩打入法一般分为单独打入法、双层围檩插桩法和分段复打法。 钢板桩单独打入法适用于桩长小于10m,且工程要求不高的钢板桩支撑施工。
  The driving method of steel sheet pile is generally divided into the single driving method, double-layer purlin inserting pile method and section re driving method. Single driving method of steel sheet pile is suitable for construction of steel sheet pile with pile length less than 10 m and engineering requirements not high.
  双层围檩插桩法是在桩的轴线两侧先安装双层围檩(一定高度的钢制栅栏)支架后,将钢板桩依次锁口咬合全部插入双层围檩间。
  The double-layer purlin inserting pile method is to install the double-layer purlin (steel fence of certain height) bracket on both sides of the pile axis first, and then insert the steel sheet pile into the double-layer purlin room in turn.
  分段复打法是在板桩轴线一侧安装好单层围檩支架,将10~20块钢板桩拼装组成施工段插入土中一定深度,形成一段钢板桩墙,即屏风墙。
  The segment redriving method is to install a single-layer purlin support on one side of the sheet pile axis, and insert 10-20 steel sheet piles into the soil to form a section of steel sheet pile wall, i.e. wind screen wall.
