Concrete drain hole forming and pipe drawing device and method
The invention discloses a concrete drain hole forming and pipe drawing device and method.The device comprises a steel pipe and a rubber air bag, the rubber air bag is connected to the outer wall of the steel pipe, a bag cavity capable of containing fluid is formed between the rubber air bag and the steel pipe, a fluid filling opening is formed in the rubber air bag, and the fluid filling opening is communicated with the rubber air bag. The outer wall of the rubber air bag is sleeved with a fixing ring, the fixing ring is connected with a supporting rod, and the supporting rod is used for supporting the steel pipe after being connected with the ground during construction. The pipe drawing device is easy to manufacture, low in price and capable of being repeatedly used in the construction process, the construction process is simple, the hole forming and pipe drawing process is simplified, and the convenience of drain hole construction during dam body concrete pouring can be remarkably improved.
本发明开发了一种混凝土排水孔成孔拔管装置及方法，该装置包括钢管和橡胶气囊，所述橡胶气囊连接在所述钢管外壁上，使所述橡胶气囊和所述钢管之间形成可容纳流体的囊腔，所述橡胶气囊上设有流体充入口，所述橡胶气囊外壁上套设固定环，所述固定环上连接支撑杆，所述支撑杆用于在施工时与地面连接后将所述钢管进行支撑。本发明的拔管装置易于制造，价格低廉，可在施工过程重复使用，且施工过程简单，简化了成孔拔管工艺，能够显著提升大坝坝体混凝土浇筑时排水孔施工的便捷性。
