Soil density measurement method and special wax-sealed paper box thereof

Abstract

The invention discloses a soil density measurement method and a special wax-sealed paper box thereof. The soil density measurement method comprises the following steps: 1) measuring volume density of A4 copy paper for making the special paper box; 2) making a planar unfolded pattern of the special paper box; 3) heating for melting solid paraffin; 4) covering a paraffin film on the planar unfoldedpattern of the special paper box; 5) measuring weight of the special wax-sealed paper box fully containing soil samples in the air; 6) measuring the weight of the special wax-sealed paper box fully loaded with the soil samples in water; 7) comparing correctness of measured data; 8) performing parallel determination twice; and 9) calculating the density of the soil samples to be measured. The special wax-sealed paper box is a cuboid which is in volume of 30 cm<3> to 40 cm<3> and manufactured by the A4 copy paper, the differences among values of length, width and height of the special wax-sealed paper box are less than or equal to 5cm, the height value is larger than the length value and the width value respectively and the paraffin film in the thickness of 0.4-0.7mm is covered inside and outside the special wax-sealed paper box.

Description

Technical field [0001] The invention relates to a soil density measurement method, in particular to a soil density measurement method for fine-grained soil, sandy soil, fine-grained gravel soil and medium-grained gravel soil. The invention also relates to a special wax-sealed carton for the method. Background technique [0002] At present, the main methods for measuring soil density are ring knife method, electric soil borrowing method, wax sealing method, irrigation method, and sand irrigation method. The ring knife method is mainly suitable for fine-grained soils that can be molded without gravel particles; the electric borrowing method is mainly suitable for hard plastic soils, and the cost is relatively high; the wax sealing method is mainly suitable for moldable and easily broken soils and shapes Irregular hard soil; irrigation method is mainly suitable for coarse-grained soil and giant-grained soil; sand-filling method is mainly suitable for on-site determination of fine-g...

AI Technical Summary

Problems solved by technology

[0004] For fine-grained soil such as sandy soil, sandy soil, fine-grained gravel soil, and medium-grained gravel soil, which are difficult to shape, it is very difficult to measure the volume of a certain quality soil sample. There is no better shaping method, so it has a great impact on the measurement accuracy of its density

In addition, there is currently no method that can measure the density of fine-grained soil, sandy soil, fine-grained gravel soil, and medium-grained gravel soil in the laboratory
