IS I 12070 • 1987 3.3 The permissible settlement for calculation of safe bearing pressure from plate load test should be taken as 12 rom even for large loaded areas. The low value for settlement offoundation is due to hetrogeneity of rocks. In case of rigid structures like R.C.C. silos, the permissible settlement may be increased judiciously, if required.

In construction terms, excavation is the process of removing earth to form a cavity in the ground. On small sites or in confined spaces, excavation may be carried out by manual means using tools such as picks, shovels and wheelbarrows. Larger scale excavation works will require heavy plant such as bulldozers and backactors.

Aug 25, 2016· • For hard soils when the depth of excavation is less than 1.5 m, the sides of the trench do not need any external support. If the soil is loose or the excavation is deeper, some sort of shoring is required to support the sides from falling. 14. EXCAVATION WORKING PROCEDURE 15.

Soil that's loose has much less bearing capacity than the original soil. That's why it is so important to compact the trench bottom. Use a vibrating plate compactor for sand or gravel soils, and a jumping jack compactor for silt or clay (learn more about compaction equipment in this guide to subgrades and subbases). If you don't compact that ...
