Construction method for quickly and non-destructively breaking pile heads
The invention discloses a construction method for quickly and non-destructively breaking pile heads. In the construction method, a pile body is included. A reinforced cage is arranged inside the pilebody; vertical main reinforcements are reserved in a pile head of the reinforced cage; a pore passage sliding sleeve is arranged on the outer surface of a sound measuring pipe; an isolation plate anda tapered sleeve are separately arranged at the upper and lower ends of the pore passage sliding sleeve; the upper and lower ends of the pore passage sliding sleeve are bonded and sealed with an adhesive tape; a lifting frame (the whole pile head is used as a marking rod before lifting) is arranged at a position where the vertical main reinforcements reserved in the pile head of the reinforced cage are not smaller than 30 cm from the top surface of the reinforced cage; and a concrete pouring pile head is within the range of the vertical main reinforcements reserved in the pile head of the reinforced cage. After the construction of the pile head is completed, a high-pressure water jet technology (also known as hydraulic breaking technology) is used for properly removing concrete from the lifting frame to the top surface of the reinforced cage, and finally the pile head is integrally hoisted by a crane, thereby completing the quick and non-destructive breaking of the whole pile head.
本发明公开了一种快速无损破除桩头施工方法，包括桩体。所述桩体的内部设有钢筋笼，所述钢筋笼桩头内预留竖向主筋和声测管的外表面设有孔道滑动套，所述孔道滑动套上下两端分别设有隔离板和锥形套并采用胶带粘连和封口，所述钢筋笼桩头内预留竖向主筋距钢筋笼顶面不低于30公分位置设有起吊架(桩头整体起吊前作为标记杆)，所述钢筋笼桩头内预留竖向主筋范围内为混凝土浇筑桩头。所述桩头施工完成后，采用高压水射流技术(也称为水力破除技术)对所述起吊架至钢筋笼顶面间混凝土进行适当破除，最后采用吊机整体起吊桩头，至此完成整个桩头的快速无损破除。
