Dutch Dynamic Cone Penetrometer DCP

"Dutch Dynamic Cone Penetrometer DCP, Dutch Dynamic Cone Penetration" is drop hammer energy will certainly use the cone-size probe into the soil. According the difficult and easy degree which when it ease into the soil (penetration)to determine the nature of an in situ soil testing methods. It only applies to the sand, clay (loess). But it usually can't be applies to the artificial soil and loose particles smaller than stone, rock, Soil containing rock and gravel, boulder clay, generic application, dynamic, while penetration can also:

1. The qualitative nature of the power sub-soil study do not have obvious difference, it may be sounding indicators show that thus the foundation of stratified layers in the evaluation of the quality of soils uniform inspection.

2. Quantitative determination of the physical nature of soil, soil physics and the use of cone penetration indicators related to the nature of establishing ties be able to establish the physical properties such as soil density of sand, clay and sandy soil bearing capacity and allow the strain modulus level. The use of empirical, penetration should meet the following conditions:

(1) What be used touches the various equipment parameter exploring, operating method responds to, as the equipment parameter, operating method building when looking at and appraising relation are fundamental.

(2)The structure and physical property testing the soil layer geology cause of formation, hiding condition, rock sex etc and the upper strata echoing building-up looking at and appraising relation Ought to be basically similar.

(3) According to the condition being hit by monotype construction works space, should grasp the experience using driving force to touch fishing for an instrument basically.
