负载作用下渣土-泡沫混合物中泡沫消散性能测定装置
摘要：
本实用新型公开了一种负载作用下渣土-泡沫混合物中泡沫消散性能测定装置，基座(1)上竖立设有套筒(9)，套筒(9)外侧轴向设有刻度(2)，套筒(9)内设有活塞(10)，活塞(10)上设有与刻度(2)对应指示的刻度指针(3)，套筒(9)的底部设有下出水口(8)，活塞(10)上设有上出水口(11)，一个测力计与活塞(10)连接，杠杆(6)的一端铰接在固定端(7)上，杠杆(6)的另一端连接有砝码(13)，杠杆(6)的中部压在活塞(10)上。本实用新型设备比较简单，容易实现，操作简单易行，试验成本低；采用这种泡沫消散鉴定方法，能够反映出泡沫在负载作用下渣土-泡沫混合物中泡沫的稳定性，对客观评价泡沫剂所具有的泡沫消散性能有利；因此，本实用新型是一种有效可靠且新颖的盾构用泡沫消散性能的鉴定装置。
摘要（英）：

The utility model discloses a device for testing the dissipation performance of foams in a muck-foam mixture in the presence of a loading effect. A sleeve (9) is vertically arranged on a base (1); the outer side of the sleeve (9) is axially provided with scales; a piston (10) is arranged inside the sleeve (9); a scale pointer (3) which is used for correspondingly indicating the scales (2) is arranged on the piston (10); a lower water discharging hole (8) is formed in the bottom of the sleeve (9); the piston (10) is provided with an upper water discharging hole (11); a force meter is connected with the piston (10); one end of a lever (6) is hinged to a fixing end (7); the other end of the lever (6) is connected with a weight (13); the middle part of the lever (6) is supported by the piston (10). The device disclosed by the utility model is relatively simple, easy to implement, simple and feasible to operate and low in testing cost; by adopting a foam dissipation identification method, the stability of the foams in the muck-foam mixture in the presence of the loading effect can be reflected; the objective evaluation on the foam dissipation performance of a foaming agent is facilitated, and therefore, the device disclosed by the utility model is an effective, reliable and novel device for identifying the dissipation performance of the foams for shields.
