8) in cutting ring, take out sample, get representative sample;
9) measure its water content: (A) get aliquot part (clay soil 5-10g, sandy soil 20-30g) put into aluminium box, leveling degree of compaction is measured case, with draught shield, keep out the wind, weigh wet soil quality in the balance, (B) with alcohol, with glue head dropper, alcohol is injected and is placed with the aluminium box of sample, until there is free surface in box; (C) level board is placed on leveling on ground, and aluminium box is placed on level board, is connected to level board surrounding keeps out the wind with draught shield, lights alcohol in aluminium box, fires to fray-out of flame; (D), by sample cooling number minute, by the method for B, C step, rekindle twice; (E) after fray-out of flame for the third time, build lid, cooling after, claim immediately dry ground quality, accurately to 0.01 g.
(2) calculate
(1) from Yu Tuzhong, get representative Specimen Determination moisture content w
Soil moisture content accounts for contained humidity weight in soil the percentage that oven-dried soil is heavy and represents, design formulas is as follows:
Water content w(% by weight)=(original soil weight-oven-dried soil weight)/oven-dried soil weight * 100%=water weight/oven-dried soil heavy * 100%;
(2) wet density of sample, should be calculated as follows:
ρ = （m2- m1 ）/ V
The density of ρ in formula---sample (g/cm3), is accurate to 0.01g/cm
3
M1---cutting ring quality;
(3) dry density of sample, should be calculated as follows:
ρd =ρ/ ( 1 + 0.01 w )；
(4) this test should be carried out twice parallel determination, and O.03g/cm the difference of twice mensuration must not be greater than
3, get the average of twice measured value;
(5) degree of compaction=ρ d/ maximum dry density * 100.
(3) performance: by provincial highway s254 moral business line, the rich eastern line of provincial highway s346, s348 jujube Cao line, the construction of s351 figured stone alignment highway engineering construction, carried out practical application, respond well, reach expectation requirement, the beneficial effect of this achievement is: design science is reasonable, simple in structure, easy to manufacture, cost is low, simple to operate, and common people also can operate, the degree of compaction case that the method is manufactured, the advantage such as convenient and swift during test, economic and practical, flexible, efficient, quick.Utility model, has solved in highway, municipal construction many defects in existing process of the test, is particularly suitable for experiment work in highway, Municipal Road Engineering, and the promptness providing and the accuracy of experimental data has been provided, and has improved construction speed.
This method is applicable to the density of fine grained soils and stabilized with inorganic binder fine grained soils.But to stabilized with inorganic binder fine grained soils, should not surpass 2d its length of time, and should be for the degree of compaction check of work progress.
Adopt alcohol to dryout method, approximately need 15 minutes, efficiency is not high, for detritus soil, humus can be burnt and is caused weightlessness, has a strong impact on precision.
Strengthen the size of degree of compaction case, cutting ring is filled with to sand cylinder instead, strengthen and measure the degree of compaction case scope of application.
