Description

Intelligent variable-pitch compaction instrument

The technical field is as follows:

the utility model relates to an intelligent displacement type compaction instrument.

Background art:

geotechnical engineering is often confronted with the problems of filling and compacting, such as road building, dam building, airport building, buried pipeline backfilling and the like. The inner structure of the filled soil is damaged after excavation, and the density and the water content of the backfilled soil are changed compared with those of the original soil. The filled soil without compaction has more pores and cavities, extremely low strength and easy instability and damage after meeting water, so that the filled soil must be compacted by adopting a certain standard. The current mature method is mainly to determine the maximum dry density of the filling through a compaction test, then determine the target dry density required to be processed by the rock-soil body in the engineering according to the selected compaction degree, and process the rock-soil body through measures such as tamping, rolling and the like.

The present compaction apparatus includes light compaction apparatus and heavy compaction apparatus, and has the basic principle that soil is filled into a compaction barrel, a heavy hammer with certain mass falls down from a certain height to repeatedly compact the scattered soil in the barrel, and the main difference between the light compaction apparatus and the heavy compaction apparatus is that the weight is different in mass and the falling distance of the heavy hammer is different. When the compaction device works, the weight is compacted, the compaction cylinder at the bottom is in a rotating state, so that the samples around the compaction cylinder can be compacted by the weight, and finally the maximum dry density of the samples is comprehensively determined by weighing the mass of the samples, combining the volume change with the final compaction curve.

The main problem of the present compaction instrument in determining the maximum dry density of the filled soil is that the dry densities of the upper, middle and lower parts of the sample are different, and through tests, the difference between the dry densities of the compacted loess sample and the loess sample is 0.05-0.20 g/cm3, the dry density of the bottom of the sample is the maximum, and the dry density of the top of the sample is the minimum, mainly because the drop distance of the weight is fixed, when the weight impacts the first layer of the sample in the compaction cylinder, the drop distance is L1, when the weight impacts the second layer of the soil sample, the drop distance of the weight is L2, and when the weight impacts the third layer of the soil sample, the drop distance of the weight is L3, because the lifted position is fixed, the weight L1 > L2 > L3, at this time, under the same mass condition of the weight, the compaction energy obtained by the bottom (first layer) of the soil body is the maximum, the dry density generated is the maximum, the middle level is the minimum, and the dry density of the top is the minimum.
