摘要
投球式逆向灌注器是利用注浆产生的压力,通过投球方式,实现机械位移控制,在地浸钻孔内完成逆向灌浆的封孔操作,并保证其具有良好的机械性能、工艺性能和可操作性。
A new type of ball-and-spigot reverse-pouring device has been developed. By the use of pressure produced by grouting cement pulp and through dropping balls into the device, the pouring device realizes the control of its mechanical displacement to reach the sealing of underground-leaching hole for reverse pouring the hole, as well as ensures its good mechanical performance, technology performance and operability.
