  钢板桩施工中,桩基有多种类型。从材料和施工方法,它们可以被分为两类,桩、预制桩,前者是混凝土泵基础上提前挖洞,设置桩基础的形成,这是直接在工厂好木头、钢或钢筋混凝土桩,到现场锤,振动和机械功率等静压到地下。
  There are many types of pile foundation in steel sheet pile construction. From materials and construction methods, they can be divided into two categories: pile and prefabricated pile. The former is to dig holes in advance on the basis of concrete pump and set up the formation of pile foundation, which is directly in the factory good wood, steel or reinforced concrete pile, to the site hammer, vibration and mechanical power isostatic pressure to underground.
  钢板打桩机的基本技术参数是冲击重量、冲击动能和冲击频率。桩锤可分为落锤、汽锤、柴油锤、液压锤等。目前有两种打桩机:柴油锤打桩机和长螺旋打桩机。钢板桩可分为:热轧/拉尔森钢板桩、冷弯薄壁钢板桩。由于生产条件和规模的限制,我国目前还没有热轧钢板桩生产线。
  The basic technical parameters of steel sheet pile driver are impact weight, impact kinetic energy and impact frequency. Pile hammer can be divided into drop hammer, steam hammer, diesel hammer, hydraulic hammer, etc. At present, there are two kinds of pile driver: diesel hammer pile driver and long screw pile driver. Steel sheet pile can be divided into hot rolled Larson steel sheet pile and cold formed thin steel sheet pile. Due to the limitation of production conditions and scale, there is no hot-rolled steel sheet pile production line in China.
  钢板桩施工中,常见的热轧钢板桩厂家有韩国现代钢、日本新日铁、日本住友钢、日本JFE钢等一些欧美厂家。冷弯桩的生产工艺和工艺要求比较容易满足,所以国内有很多厂家。拔桩困难的原因:连接锁锈蚀变形严重;钢板桩打入密砂层;当挖土支护不及时时,钢板桩变形:振动锤再次打击,克服与土壤的粘附和咬合之间的锈蚀等阻力。将桩按板桩的相反顺序拉出。
  In the construction of steel sheet pile, the common hot rolled steel sheet pile manufacturers include Korea modern steel, Nippon Steel, Sumitomo steel, Japan JFE steel and some other European and American manufacturers. Cold-formed pile production technology and process requirements are relatively easy to meet, so there are many domestic manufacturers. The reasons for difficulty in pulling out piles are: serious corrosion deformation of connection lock; steel sheet pile driving into dense sand layer; when excavation support is not timely, steel sheet pile deformation: vibration hammer strike again to overcome resistance such as rust between soil adhesion and occlusion. Pull the piles out in the opposite order of sheet piles.
  承受土压力的一侧土体比较密实,在附近打入另一桩板桩,将原板桩顺利拉出。侧槽中,放入膨润土浆,拉出桩体可减小阻力。钢板桩围堰不适合在大卵石、坚硬岩石的河床上使用。钢板桩的力学性能和尺寸应满足规定的要求。钢板桩打入前,应在围堰上下游及围堰两侧设置测点和观测点,控制围堰长边和短边的位置。必须提供导向设备,以确保钢板桩的正确位置。

  The soil on one side of bearing earth pressure is relatively dense. Another sheet pile is driven into the vicinity and the original sheet pile is pulled out smoothly. In the side groove, bentonite slurry is put in, and the resistance of the pile can be reduced by pulling out the pile body. Steel sheet pile cofferdam is not suitable for use on the river bed with large pebbles and hard rocks. The mechanical properties and dimensions of steel sheet piles should meet the specified requirements. Before the steel sheet pile is driven into the cofferdam, the locations of long and short sides of the cofferdam should be controlled by setting observation points and observation points on both sides of the cofferdam and upstream and downstream of the cofferdam. Guiding equipment must be provided to ensure the correct location of steel sheet piles.
  钢板桩施工前,应先用钢板桩锁止水堵料,防止渗漏。罢工的顺序通常是从上游到下游。拉森钢板桩振动驱动和桩拉方法是使用高频液压振动锤应用钢板桩振动能力,干扰土壤,使土壤液化,破坏之间的摩擦阻力和吸附,钢板桩,并施加压力或举升力插入或取出钢板桩。
  Before the construction of steel sheet piles, steel sheet piles should be used to lock water and plug materials to prevent leakage. The order of strikes is usually from upstream to downstream. The vibration driving and pulling method of Larsen steel sheet pile is to use high frequency hydraulic vibration hammer to apply the vibration ability of steel sheet pile, disturb soil, liquefy soil, destroy friction resistance and adsorption, steel sheet pile, and apply pressure or lift force to insert or take out steel sheet pile.
