Description

Combined measuring device for slurry fluidity of granular grouting material

Technical Field

The utility model relates to a slip casting material capability determination technical field particularly, relates to a joint measurement device of granule type slip casting material thick liquid mobility.

Background

The grouting technology widely applied to engineering has been used for hundreds of years, and various grouting materials are formed. The chemical grouting material can be tested by referring to the conventional physical and chemical performance test method and the test method of the petrochemical industry, and can basically meet the grouting engineering requirement. However, the performance test of the granular grouting materials such as cement-based grouting materials and clay with the widest application mostly depends on the test means and methods of civil engineering materials, drilling mud and geotechnical tests, a set of unified method suitable for the performance test of the granular grouting materials cannot be formed, and the test result often cannot meet the requirements of grouting engineering.

The current test aiming at the fluidity of the granular grouting material mainly comprises a net slurry fluidity method (a disc method) (GB/T8077-2012 concrete admixture homogeneity test method, S L62-2014 Hydraulic engineering building cement grouting construction technical specification), a table jump method (GB/T2419-.

The disc method and the jump table method measure the fluidity by measuring the average diffusion distance of the measured material on the disc, the Marshall cylinder method measures the fluidity by measuring the time required for filling the measured material into a 200ml volumetric cylinder, but in view of the fact that the Marshall cylinder method has a plurality of operation influence factors (the vertical condition of the cylinder, the observation of the volumetric cylinder, the recording of the time and 2-3 persons required for the test), has large influence on the fluidity measurement, and is more difficult to accurately control the measurement of the granular grouting material slurry with small consistency. Therefore, the fluidity test of the granular grouting slurry material mainly adopts a disc method and a jump table method.

The net slurry fluidity method (disc method) is widely used, but is only suitable for slurry with moderate consistency, is not suitable for the disc size limitation of the particle type grouting material slurry with larger consistency, and cannot be used for the particle type grouting material slurry with small consistency due to poor fluidity. At present, a flow test is carried out on the particle type grouting material slurry with small consistency by adopting a jump table method. Therefore, the test devices for the slurry fluidity test of the same type of particle grouting materials with different proportions (different proportions and different consistencies) are different, and the operation is inconvenient in the specific test process.

The disc method is small in consistency range of applicable slurry, low in precision (the truncated cone circular mould is strickled off and shaken, bottom slurry leakage and water seepage are caused, and levelness of a circular plate is difficult to guarantee), and pure manual operation is generally adopted, so that artificial subjective factors (speed of manually lifting the truncated cone circular mould, verticality and lifting height in a lifting process, and maximum vertical distance is compared by using a ruler) have large influence on a measurement result. The jump table method mostly adopts semi-automatic test, is applicable to slurry materials with small consistency, and similarly, measurement result errors generated by artificial subjective factors (shaking, vibrating uniformity, artificial lifting and cutting speed and lifting verticality of a jump table test mold, and maximum vertical distance is compared by a straight ruler) are large. Due to the above problems, the accuracy, repeatability and precision of the fluidity measurement test result are difficult to guarantee.

Therefore, there is a need to develop a device and a method for measuring the slurry fluidity of a granular grouting material, which have a wide application range of slurry consistency, convenient operation, and high measurement accuracy and precision.
