Construction method for rapidly breaking pile head of cast-in-place concrete pile
The invention provides a construction method for rapidly breaking a pile head of a cast-in-place concrete pile. The construction method comprises the following steps that a cast-in-place pile reinforcement cage is manufactured, and a pile head reserved steel bar of the part, embedded into a bearing platform, of the reinforcement cage is wrapped; concrete is poured, and it is ensured that concrete cement paste does not enter the steel bar main reinforcements in the pouring process; and the pile head of the cast-in-place pile is excavated, a line is drawn and marked at the preset position, and a cutting machine and a percussion drill are used for cutting and drilling treatment at the corresponding position till a circle of concrete interface is completely fractured. The method has the advantages that the breaking difficulty of the pile head of the cast-in-place concrete pile can be reduced, the construction quality of the pile head of the cast-in-place concrete pile can be guaranteed, in the implementation process, the construction period is short, the construction efficiency is high, the construction quality is good, and good economical efficiency is achieved on the pile head breaking construction cost.
本发明提供了一种一种快速破除混凝土灌注桩桩头的施工方法，包括如下操作：灌注桩钢筋笼制作，钢筋笼嵌入承台部分的桩头预留钢筋进行包裹处理；混凝土浇筑，浇筑过程中确保混凝土水泥浆不进入钢筋主筋内；灌注桩桩头开挖，在预设位置画线标注，并使用切割机及冲击钻在相应的位置进行切割钻孔处理，直至混凝土界面一圈完全断裂。本发明的优点：既可以降低混凝土灌注桩桩头破除难度，又可以保证灌注桩桩头施工质量，本发明实施过程中施工周期短，施工效率高，施工质量好，以及对桩头破除施工造价有较好的经济性。
