1101. DESCRIPTION 1101.1. This work shall consist of con struction of all types of piles for structures in accordance with the details shown on the drawings and conforming to the requirements of these specifications. 1101.2. The construction of pile foundations requires a careful choice of the piling system depending upon sub-soil conditions and loading characteristics and type of structure. The permissible limits of total and differential settlements, unsupported length of pile under scour, impact/entanglement of floating bodies and any other special requirements of project are also equally important criteria for selection of the piling system. The method of installing the piles, including details of the equipment shall be submitted by the Contractor and got approved from the Engineer. 1101.3. The work shall be done as per IS:2911 except as modified herein. 1102. SUB-SURFACE INVESTIGATION 1102.1. The complete sub-surface investigation of strata in which pile foundations are proposed shall be carried out in advance and by in-situ pile tests. For details of geotechnical sub-surface explorations reference may be made to Section 2400. At least one bore-hole for every foundation of the bridge shall be executed. Borings should be carried upto sufficient depths so as to ascertain the nature of strata around the pile shaft and below the pile tip. However, depth of boring shall not be less than : i) 1.5 times estimated length of pile in soil but not less than 15 m beyond the probable length of pile ii) 15 times diameter of pile in weak/jointed rock but minimum 15 m in such rock iii) 4 times diameter of pile in sound, hard rock but minimum 3 m in such rock 1102.2. The sub-surface investigation shall define adequately stratification of sub-strata including the nature and type of strata, its variation and extent and specific properties of the same. The investigation shall be adequate for the purpose of selection of appropriate piling system and for estimating design capacities for different diameters and length of piles. 1102.3. Pressure meter tests may be used in the case of rock, gravel or soil for direct evaluation of strength and compressibility characteristic. Though these tests are of specialised nature they are most appropriate for difficult/uncertain sub-strata especially for important projects. 1102.4. For piles socketed into rocks, it is necessary to determine the uniaxial compressive strength of the rock and its quality. The investigation shall also include location of ground water table and other parameters including results of chemical tests showing sulphate and chloride content and any other deleterious chemical content in soil and/or ground water, likely to affect durability. 1103. TYPE OF PILES The piles may be of reinforced concrete, prestressed concrete, steel or timber. The piles may be of solid or hollow sections or steel cased piles filled with concrete. Concrete piles may be driven cast-insitu or precast or bored cast- in-situ or precast piles driven into preformed bores. The shape of piles may be circular, square, hexagonal, octagonal, "H" or "I" Section. 1104. MATERIALS 1104.1. The basic materials shall conform to the specifications for materials given in Section 1000. The specifications for steel reinforcement, structural concrete, prestressed concrete and structural steel to be used in pile foundations shall be as given in the relevant sections. 1104.2. Concrete in Piles Grade of concrete to be used in cast- in-situ piles shall not be less than M 20 and the cement content shall not be less than 400 kg per cubic meter of concrete. Grades of concrete for precast reinforced and prestressed concrete piles shall not be less than M 25 and M 35 respectively. Maximum water cement ratio shall be 0.5 for cast- in-situ piles and 0,45 for precast piles. The minimum slump of concrete for driven cast- in-situ piles shall be 100 mm to 150 mm and that of bored cast- in-situ piles 150 mm to 200 mm. The slump should not exceed 200 mm in any case. Concrete mix should have homogeneous mixture with required workability for the system of piling adopted. Suitable and approved admixtures may be used in concrete mix where necessary. Where piles are exposed to action of harmful chemicals or severe conditions of exposure due to presence of sulphate, chloride etc, it may be preferable to opt for higher grades of concrete restricting water cement ratio to 0,45. Special types of cement, such as sulphate resistant cement may - be used where considered appropriate.
