Water Canal | Channel Making Machine , Paving machine : construction of north canal

according to code Lining of canals is an important feature of irrigation projects as it improves the flow characteristics and minimizes the loss of water due to seepage. The water thus saved can be utilized for the extension and improvement of irrigation. Lining of water courses in the areas irrigated by tube wells assumes special significance as the pumped water supply is relatively more costly. The reduced seepage also prevents rise of the sub-soil water table and thus reduces the possibility of damage to the adjoining areas by water logging. Further, due to adoption of higher velocities in a lined canal there is a saving in the cross-sectional area of the canal and land width required, with corresponding saving in the cost of excavation and masonry works. It helps in retention of shape of the canal. Lining also results in improvement of command and larger working head for power generation. The functions of lining ure: a) Seepage control, b) Prevention of water logging, c) Increased hydraulic efficiency, d) Increased resistance to erosion/abraison, e) Reduction in cross-section area and consequential smaller structures, and J) Low operation and maintenance cost in this video full construction of canal has been shown. 1. excavation of pit. 2. spreading of sheets to avoid water percolation. 3. lining of concrete with paver machine. 4. curing of concrete. DIFFERENT TYPES OF LININGS a) Rigid Lining I) Stone-pitched lining; 2) Burnt clay tile or brick lining; 3) Precast cement concrete/stone slab lining; 4) In-situ cement lime/concrete lining; 5) Stone masonry lining; 6) Soil cement lining; 7) Shotcrete lining; and 8) Asphaltic cement/concrete. b) Flexible Lining I) Geomembrane like High Density Polyethylene (HDPE), Polyvinyl chloride (PVC,) Low Density polyethylene (LDPE) cover comprising layer of ben to rite with adequate/ earth/burnt clay tile brick/precast cement concrete, 2) Bituminous or bituminous/asphaltic felt lining, 3) Fibre reinforced plastic tissue as phallic membrane, and 4) Composite membrane/rubber lining. after watching this video you will be able to understand how to construct canal or how to build canal. also you will see how to prepare sub grade. then how to lining the canal. the canal lining has done by using canal lining paver machine. concrete canvas channel lining. #canalconstruction #concretepavermachine #canallining #irrigation #civilengineeringvideos construcción de canales Our face book page : real civil :   / civilnerd   Our telegram page : civil engineering video : https://t.me/realcivil Instagram page link : https://instagram.com/real.civil?igsh...
