Construction method of damage-free fender post
The invention discloses a construction method of a damage-free fender post. The construction method comprises the following steps that S1, punching operation is conducted according to a preset position to form a pouring hole; s2, hanging bars are in lap joint with main bars on the corresponding fender post reinforcement cages, and the hanging bars are subjected to isolation treatment; s3, the fender post reinforcement cage sinks to a preset position in the pouring hole, and concrete is poured into the pouring hole to form a fender post; s4, earthwork is excavated in the area defined by the fender posts, and after excavation is conducted to the preset height, a surrounding purlin pouring steel bar framework is built at the preset height of the fender posts; s5, breaking the isolation of the hanging bar, and bending the hanging bar to a preset position so as to be connected with the enclosing purlin pouring steel bar framework; and S6, the enclosing purlin pouring steel bar framework is poured to form the enclosing purlin. According to the construction method capable of avoiding damage to the fender post, the construction efficiency is improved, the anti-bending bearing capacity of the fender post is not affected, welding work does not need to be conducted in a foundation pit, and the connecting strength of the hanging bars and the fender post reinforcement cage is not affected.
一种免破坏围护桩的施工方法，包括如下步骤：S1，按照预设位置进行打孔操作形成浇筑孔；S2，将吊筋搭接在对应的围护桩钢筋笼上的主筋上，且对所述吊筋进行隔离处理；S3，将所述围护桩钢筋笼下沉至浇筑孔内的预设位置，并向所述浇筑孔内浇筑混凝土以形成围护桩；S4，在围护桩围成的区域内开挖土方，在开挖至预设高度后，在围护桩的预设高度处搭建围檩浇筑钢筋骨架；S5，破除所述吊筋的隔离，并将所述吊筋弯制至预设位置以连接围檩浇筑钢筋骨架；S6，对所述围檩浇筑钢筋骨架进行浇筑以形成围檩。该免破坏围护桩的施工方法，提升了施工效率，且不会影响围护桩的抗弯承载能力，无需在基坑内进行焊接工作，不会影响吊筋与围护桩钢筋笼连接的强度。
