The Sinking of the Well Foundation is carried out through the following Steps. Laying of Curbs, Sinking of the Well Foundation In dry ground excavate up to 50 cm in river bed and place the cutting edge at the required position. If the curb is to be laid under water and depth of water is greater than 5 m, prepare Sand Island and lay the curb. If depth of water exceeds 5 m built curb in dry ground and float it to the site. A typical sand island is shown…

What are the Component Parts of a Well Foundation A section through a well foundation is shown in figure 1. The various component parts of a Well Foundation are briefly described in the following. Well Cap – The well cap is a RCC slab of sufficient strength to transmit the forces from pier to the body of well. It is generally kept at low water level. The dimension of the well cap should be sufficient to accommodate the pier. The recommended minimum thickness is 0.75 m. Steining – It is…

What is Caissons? The term caisson is derived from Latin, which means box or case. Caissons are hollow inside and usually constructed at site and sunk in place into a hard bearing stratum. Often the caissons have high construction cost and their construction is restricted to major foundation works. Caissons are used for bridge piers, abutments in rivers and lakes, docks and wharves, break water and other shore protections works, and large water front structures such as pump houses subjected to very heavy vertical and horizontal loads. Advantages of Caissons…
