Checklist for cone penetration method

The usefulness of SPT results depends on the soil type, with fine-grained sands giving the most useful results, with coarser sands and silty sands giving reasonably useful results, and clays and gravelly soils yielding results which may be very poorly representative of the true soil conditions. The study results indicate that the resistance of sludge in the sampled latrines is dependent on the pit type and groundwater conditions. Methods and Interpretation discusses the history, applications, and development of the cone penetration test procedures and related test procedures. Fluidization during pit emptying also requires additional equipment, expertise, and labor. Leslie Youd , and others.

Cone penetration testing : methods and interpretation

Designed and maintained by TN Integrated Solutions. The reference point was used to measure the penetration depth after the application of a consistent impact against a reference point marked on the latrine slab. In some unlined latrines, the sludge near the surface was soft and the strength increased rapidly with depth. The AggreBind surface seal will normally cure within 2 hours. Abstract Pit latrines can provide improved household sanitation, but without effective and inexpensive emptying options, they are often abandoned once full and may pose a public health threat. Apparatus A flat, glass plate of which a convenient size is 10 mm thick and about mm square.

Cone penetration testing : methods and interpretation (eBook, ) []

If the overall range is then not more than 1 mm record the average of the three penetrations and proceed to Step No. The reference point was used to measure the penetration depth after the application of a consistent impact against a reference point marked on the latrine slab. Low sludge resistance layers mainly occurred near the surface while lower depths exhibited relatively higher resistance dense sludge.

A comparative study of fecal sludge management in Malawi and Zambia: Construction Industry Research and Information Association: It is also easier to perform and gives more reproducible results.

Physical Sciences Physical Sciences: Standard Penetration Test blow counts do not represent a simple physical property of the soil, and thus must be correlated to soil properties of interest, such as strength or density. The cone is able to delineate even the smallest 0. Flexible - Read on multiple operating systems and devices. We are always looking for ways to improve customer experience on Elsevier. The sludge characteristics of lined and unlined pits are different and therefore likely to have different emptying technical needs; the value of using the penetrometer is that emptying service providers can tease out these differences and target them appropriately. However, a study limitation is that the zone of influence around the cone is limited.

At the beginning you're like "WTF?" but then it gets better and better the more you watch it. It even makes sense by the end. Where did you catch this? Who is the chick?
