Device for preventing pile core concrete from falling
The invention provides a device for preventing pile core concrete from falling off and a construction method, the device comprises a bottom supporting plate, a protection pipe and an air bag, the protection pipe and the air bag are located on the two sides of the bottom supporting plate respectively, an inflation pipe of the air bag is arranged in the protection pipe in a penetrating mode, and the section size of the inflated air bag is larger than that of the bottom supporting plate; a plurality of lap joint rods are arranged on the outer wall of the protection pipe, are located at the top of the protection pipe and extend in the radial direction of the protection pipe; a flange plate is arranged at the top of the protection pipe, and a detachable plugging plate is arranged on the flange plate. The air bag can block the gap between the bottom supporting plate and the inner wall of the pile hole, the problem that the compactness of the pile bottom is reduced due to the fact that unsolidified pile core concrete falls down from the gap is solved, and the construction quality and the construction efficiency of a pile foundation are improved; the protection tube can protect the inflation tube and prevent the inflation tube from being punctured and leaked, and can also serve as a carrier of the lap joint rod, so that the erection stability of the bottom supporting plate and the air bag is improved through the lap joint rod.
本发明提供一种防止桩芯混凝土掉落的装置及施工方法，该装置包括底托板、保护管和气囊，保护管和所述气囊分别位于所述底托板的两侧，所述气囊的充气管穿设于所述保护管中，所述气囊在充气后的截面尺寸大于所述底托板；所述保护管的外壁设有若干个搭接杆，所述搭接杆位于所述保护管的顶部，其沿所述保护管的径向延伸；所述保护管的顶部设有法兰盘，所述法兰盘上设有可拆卸的封堵板。本发明中的气囊可封堵底托板与桩孔内壁的间隙，防止未凝固的桩芯混凝土从间隙处落下，导致桩底密实度降低等问题，提高桩基础的施工质量和施工效率；保护管可以对充气管进行防护，防止其被扎漏，还可作为搭接杆的载体，以便利用搭接杆提高底托板和气囊的架设稳定性。
