吴县桥梁管理处在兴建白洋湾煤场和南门煤场工程的施工中,采用了 V_(86)型砼真空吸水装置,本文主要介绍该装置的特点及应用效果。一、V_(86)型真空吸水装置的特点1.吸水口位置吸水口是 V_(86)型柔性吸垫抽真空时吐出水分的“咀巴”,它一般设置在吸垫的中部,因此进行真空作业时,操作人员必须踩在吸垫上方能安装连接真空泵的软管,给操作带来一定的麻烦。为此,我们将吸水口位置从吸垫中间移到吸垫的一侧边,试验证明,经这样改进后的吸垫同样能达到吸水口在中间时的吸水效果。这是因为气垫薄膜真空腔真空度分布比较均匀,空间水阻较小的
In the construction of Baiyangwan Coalfield and Nanmen Coalfield Project, Wuxian Bridge Management Department adopted the V_(86) type helium vacuum suction device. This article mainly introduces the features of the device and its application effect. First, V_ (86) type vacuum suction device features 1. Absorbent mouth position Absorbent mouth is V_ (86) type flexible suction pad when evacuated when the water “juba”, it is generally set in the middle of the pad, so proceed In vacuum operation, the operator must step on the suction pad to install the hose that connects the vacuum pump, causing some troubles for the operation. For this reason, we moved the position of the suction mouth from the middle of the suction pad to the side of the suction pad. Tests have proved that the suction pad after such improvement can also achieve the water absorption effect when the suction port is in the middle. This is because the air-cushion film vacuum chamber has a more uniform vacuum distribution and a smaller space water resistance.
