Problems solved by technology

[0003] The loose coefficient of soil is affected by its own properties and the surrounding environment, and the randomness is relatively large. At present, there are no instruments and specifications for measuring the loose coefficient of soil. Therefore, it is difficult to accurately measure the loose coefficient of soil.

Abstract

The invention discloses a soil loosening coefficient measurement device. The device includes a soil taking bounding frame, steel chisel caps and steel chisels; circular holes are formed in the soil taking bounding frame through drilling; a bubble level gauge is installed on each steel chisel cap, and a threaded hole is formed in the bottom of each steel chisel cap; a threaded head matched with thecorresponding threaded hole is arranged on the top of each steel chisel, and the bottom of each threaded head is sharp. The device at least has the following advantages that the soil loosening coefficient measurement device and a method are provided in order to solve the problem that there are no soil loosening coefficient measurement instruments and standards at present; the arranged steel chisel caps can expand the stress areas of the upper portions of the steel chisels, and meanwhile, since the bottom of each steel chisel is sharp, convenience is provided for inserting the steel chisels into soil; each bubble level gauge is installed in a cap cylinder, and therefore the perpendicularity of each steel chisel inserted into the soil can be judged anytime and adjusted in time; the soil loosening coefficient measurement device is concise in structure and convenient to operate, the soil loosening coefficient can be measured conveniently and accurately, and the requirements of construction and design units can be met.

Description

technical field [0001] The invention relates to the field of civil engineering construction, in particular to a device and method for measuring the looseness coefficient of soil. Background technique [0002] The looseness of the soil means that after the excavation of the natural undisturbed soil, the original dense soil becomes scattered and its volume increases. After the excavated soil is backfilled and compacted, its volume still cannot return to the original state. This property of the soil Become the looseness of the soil. The looseness of the soil can be expressed by the initial loose coefficient, which is equal to the ratio of the loose volume of the soil after excavation to the volume of the soil in the natural state before excavation. In construction engineering, the looseness of soil has a great influence on the selection and excavation of earthwork transportation tools and the calculation of leveling volume. In shield tunnel construction, the control of soil d...
