During the use will try the vertical connection of mould, then be fixed in the base through fixed part on, utilize the hopper to pour into the ground paste into the position of two-thirds in trying the mould during the measurement, through trying the initial ground paste height of scale record on the mould, then put into maintenance case maintenance to the regulation maintenance age, record its calculus body height, calculate calculus rate through the formula.
Description
Technical Field
The utility model relates to slip casting material calculus survey field especially relates to a novel laboratory survey with slip casting material calculus rate device.
Background
The grouting material is the main substance which plays a role in filling and consolidating in the cracks and pores of the stratum and is the key for realizing the water plugging or strengthening effect. In recent years, grouting materials are widely applied to the fields of road grouting reinforcement, mine goaf filling, filling of gaps in tunnel caverns and the like. The calculus rate of the grouting material is a key detection index, and the calculus rate refers to the ratio of the initial volume V of the grout to the solidified calculus volume Vs, and is expressed in percentage. Under the condition that the strength index of the grouting material is met, the higher the calculus rate is, the better the reinforcing effect of the grouting material is.
However, in the current laboratory and research process, a special calculus rate measuring device is not provided, a measuring cylinder is often selected as a test mould in the experimental process, the height change of the slurry is measured by a visual scale value or a ruler measurement mode after the measuring cylinder is placed for a period of time, the measuring cylinder is made of common glass or plastic, the strength is low, the measuring cylinder is easy to wear and break, and the measuring cylinder cannot be used for other experiments due to deformation and breakage after the experiment is finished, so that the waste of resources is caused; the grouting material test block after the test is finished needs to be subjected to a series of tests of strength, durability and the like, and the existing calculus rate measuring device cannot keep the integrity of the test block when demoulding, so that the subsequent test is influenced, and the complexity of the test is increased.
