Pile foundation construction method adopting limiting steel box
The invention provides a pile foundation construction method adopting a limiting steel box, which comprises the following steps of: inserting a steel casing for pile foundation construction along a preset boundary of a foundation pit, and drilling a hole in the steel casing; a limiting steel box is inserted and hit in the preset position of the steel casing and along the steel casing; a prefabricated pile foundation reinforcement cage is placed according to the limiting steel box, and pile foundation concrete is poured; and after the concrete is initially set, the limiting steel box is pulled out, so that a guide groove for second-stage groove construction is reserved in the formed pile foundation. According to the pile foundation construction method, the limiting steel box is arranged in the pile foundation construction process, so that the preset guide grooves can be formed in the two sides, along the foundation pit preset boundary circumference, of the pile foundation, the guide effect is provided for subsequent second-stage groove construction, the construction steps are simplified, chiseling and milling of grooves in the formed pile foundation are not needed, damage to the pile foundation structure is avoided, and the construction efficiency is improved. The construction is convenient.
本申请提供一种采用限位钢箱的桩基施工方法，包括以下步骤：沿基坑的预设边界插打桩基施工用钢护筒，并在钢护筒内部钻孔；在钢护筒预设位置处并沿钢护筒插打限位钢箱；根据限位钢箱安放预制的桩基钢筋笼，浇筑桩基混凝土；待混凝土初凝后，拔除限位钢箱，以在成形的桩基预留出二期槽施工的导向槽。本申请的桩基施工方法通过在桩基施工过程中设置限位钢箱，从而可在桩基沿基坑预设边界周线的两侧形成预设的导向槽，以为后续的二期槽施工提供导向作用，简化了施工步骤，无需在成形的桩基上凿铣成槽，避免对桩基结构造成破坏，施工方便。
