The invention relates to the technical field of earthwork, and discloses a method for detecting the shrinkage performance of a muck fluidized backfill material, which comprises the following steps: S01, building muck fluidized backfill material shrinkage performance detection equipment; firstly, laying filter paper on a bottom plate, erecting a cylindrical model on the filter paper, and placing a lower permeable plate; pouring the muck fluidized backfill material sample to a set height, and placing an upper permeable plate; measuring the distance L between the top surface of the upper water permeable plate and the upper end surface of the cylindrical model at the detection point; S02, putting the equipment for detecting the shrinkage performance of the muck fluidized backfill material into a drying oven, and measuring the variable quantity of the distance L by using a dial indicator at set time intervals and recording the variable quantity; and S03, evaluating the shrinkage performance of the muck backfill material sample according to a measurement result. According to the invention, the water loss state of the muck fluidized backfill material in a real high-temperature environment is simulated; and the height variation in the water loss process can be accurately measured through the dial indicator, and the shrinkage performance of the muck fluidized backfill material can be conveniently evaluated.
Description
technical field [0001] The patent of the present invention relates to the technical field of earthworks, in particular, to a method for detecting the shrinkage performance of fluidized dregs backfill materials. Background technique [0002] Muck is a kind of construction waste. According to the "Regulations on the Management of Urban Construction Waste", the term "construction waste" refers to the waste soil generated by the construction unit, the construction unit, new construction, reconstruction, expansion and demolition of various buildings, structures, pipe networks, etc., as well as the process of residential decoration. , discarded materials and other waste. [0003] Slag fluidized backfill material is a kind of backfill material with high fluidity produced with slag, water, adhesive and additives as the main raw materials. After the adhesive is cured, it can form a certain strength and is suitable for various ditches, grooves, etc. backfill. [0004] Due to its hi...
