Construction method of shallow broken pile reinforcing structure of engineering pile and reinforcing structure of shallow broken pile reinforcing structure
The invention discloses a construction method of a shallow broken pile reinforcing structure of an engineering pile and the reinforcing structure of the shallow broken pile reinforcing structure. The construction method comprises the following steps that a hole is drilled in an area defined by stirrups of the engineering pile and drilled to the position below a broken joint of the engineering pile; the prefabricated shallow broken pile reinforcing structure of the engineering pile is placed in the excavated hole; the bottom of the shallow broken pile reinforcing structure of the engineering pile is located below the broken joint, and the top of the shallow broken pile reinforcing structure of the engineering pile is located above the broken joint; and concrete with the strength higher than that of an original broken pile is poured to the elevation of the pile top, and broken pile reinforcing is completed. According to the construction method of the shallow broken pile reinforcing structure of the engineering pile, the excavated hole is formed in a pile core of the engineering pile, the shallow broken pile reinforcing structure of the engineering pile is placed in the excavated hole, the bottom of the shallow broken pile reinforcing structure of the engineering pile is located below the broken joint, and the top of the shallow broken pile reinforcing structure of the engineering pile is located above the broken joint, and connection reinforcing of pile foundation concrete above and below the broken joint is achieved; and by means of the high-strength characteristic and the shear-bearing capacity of the shallow broken pile reinforcing structure of the engineering pile, a pile foundation obtained after overall repairing has better pile foundation pressure resistance and shear-bearing capacity.
本发明公开了一种工程桩浅层断桩加固结构施工方法及其加固结构，包括如下步骤，在工程桩箍筋围成的区域内钻孔，并钻至工程桩断缝位置以下；将预制的工程桩浅层断桩加固结构放置在开挖孔内；工程桩浅层断桩加固结构底部处于断缝以下，顶部处于断缝以上；灌注强度高于原断桩强度的混凝土至桩顶标高，完成断桩加固；本发明的工程桩浅层断桩加固的施工方法是在工程桩桩芯内设置开挖孔，并在内部放置工程桩浅层断桩加固结构，保证其底部处于断缝以下，顶部处于断缝以上，实现了对断缝上下处桩基混凝土的连接补强，并利用工程桩浅层断桩加固结构的高强度特性以及本身的抗剪能力，使得整体修补后的桩基具有更良好的桩基抗压以及抗剪能力。
