The pore water pressure meter in order to measure the pore water pressure operation to the mountain stop wall by soil cylinder string construction method

摘要

(57) Abstract Objective While operation to the mountain stop wall by soil cylinder string construction methodBy the soil cement without inhibiting the measurement function of the opening water pressureIt is to offer the pore water pressure meter which it can maintain. Constitution The pore water pressure meter usually, the sensor face (104 '') displacementIn order to detect the instrument itself (101) the second conversion which is providedThe vessel (102,103) with, the filter which is laid out outside the sensor face (106) With, the hippopotamus in order containment this filter in the instrument itself- (107) with it possesses. soiruse which is filled inside the soil cylinder stringIn order to isolate the filter of the pore water pressure meter from the mento liquid,The ice (110) it charges between the filter and the cover. This gapHydraulic meter inside soil cylinder string after the installing, with lapse of time as for iceIt dissolves, but to harden also the soil cement liquid that way, fillThe ice to remain behind between ta and the soil cement, the eye zu of the filterConservation the ball.
