Methods of Soil Exploration: Open excavation, boring & Geophysical methods

  Methods of Soil investigation or Soil exploration Soil Exploration or Soil Investigation can be done by any of the following methods - Open excavation or direct methods Boring or semi-direct methods Geophysical methods or indirect methods 1. Open excavation – In this method of exploration an open excavation is made to inspect the soil strata. This method can be divided into two categories:      (i)  Pits and Trenches      (ii) Drifts and Shafts (i) Pits and Trenches - Pits and trenches are excavated at the site to inspect the strata. The size of the pit should be sufficient to provide necessary working space. IS: 4453-1967 recommends a clear working space of 1.2 m into 1.2 m at the bottom of the pit. The depth of the pit depends upon the requirement of the investigation. Shallow pits up to a depth of 3 m can be made without providing any lateral support. For deeper pits, especially below the ground water table, the lateral support in th...

Manufacturing process of bricks: Preparation, Moulding, Drying and Burning

Manufacturing process of bricks In the process of manufacturing bricks, the following four distinct operations are involved: (1) Preparation of clay (2) Moulding (3) Drying (4) Burning.  (1) Preparation of clay -  The clay for bricks is prepared in the following order: (¡) Unsoiling (ii) Digging (iii) Cleaning (iv) Weathering (v) Blending (vi) Tempering. (i) Unsoiling - The top layer of soil, about 200 mm in depth, is taken out and thrown away. The clay in top soil is full of impurities and hence it is to be rejected for the purpose of preparing bricks. (ii) Digging - The clay is then dug out from the ground. It is spread on the levelled ground, just a little deeper than the general level of ground. The height of heaps of clay is about 600 mm to 1200 mm. (iii) Cleaning -  The clay, as obtained in the process of digging, should be cleaned of stones, pebbles, vegetable matter, etc. If these particles are in excess, the clay is to be washed and screened. Such a process natur...
