Hammering construction method of pipe bottom of steel pipe pile
The invention discloses a hammering construction method of the pipe bottom of a steel pipe pile. The hammering construction method comprises the steps that a cylindrical hammer is lifted to a preset height by using a pulley assembly; the cylindrical hammer is separated from the pulley assembly to falls freely, and depends on potential energy of the cylindrical hammer to impact a pile base fixedlyarranged inside the steel pipe sharp pile, so that the steel pipe sharp pile is driven underground; and the lifting and free falling processes of the cylindrical hammer are repeatedly executed, so that the steel pipe sharp pile is driven into soil step by step. According to the hammering construction method, the cylindrical hammer is suddenly loosened after being lifted to a certain height by using the pulley assembly, and the cylindrical hammer falls freely, and depends on potential energy of the cylindrical hammer to impact the pile base, so that the steel pipe sharp pile moves downwards, the hammering construction method can be suitable for the working conditions that a site is very narrow and a pile machine cannot enter, and be used for the condition that an anchor rod cannot be embedded into an existing house foundation, or the weight of a house cannot provide file pressing counter force, the cylindrical hammer is located inside the steel pipe sharp pile, noise is low, no vibration exists, the working efficiency is high, and the hammering construction method is very suitable for engineering pile foundation construction of storey-adding transformation of existing buildings, deviation rectification of dangerous buildings and the like.
本发明公开了一种钢管桩管底锤击施工方法，其包括：利用滑轮组件将柱形锤提升至预设高度；使柱形锤脱离滑轮组件而自由落体，依靠自身势能冲击固定地设置在钢管尖桩内部的桩底座，使钢管尖桩打入地下；重复执行柱形锤的提升和自由下落过程，使钢管尖桩逐步打入土中。本发明利用滑轮组件提升柱形锤至一定高度后突然松开，柱形锤自由落体，依靠自身的势能冲击桩底座，使钢管尖桩下移，可以适用于场地非常狭小、桩机无法进入的工况，也用于现有房屋基础无法埋设锚杆或房屋自身重量无法提供压桩反力的情况，柱形锤位于钢管尖桩内部，噪音小，无震动，工作效率高，非常适用于既有建筑的增层改造和危房的纠偏等工程桩基础施工。
