| 3 | Manufacture ,Supply and installation of Integrated Drainage Composite Different types of drainage systems have been used successfully in the waste management industry for decades, but IDC is the most predictable, reliable and effective of all. IDC offers the advantages of other types of drainage geocomposites, while overcoming most of their limitations. Some concerns like long term creep, geotextile intrusion, delamination, perimeter tying, etc. are well taken care of with the IDC application. IDC combines the perforated pipes and geosynthetic technology into a unique package offering superior long term drainage capacity and performance. IDC drainage geocomposites allow geomembrane leak detection surveys using geo-electrical methods. Standard 300 m2 (3,200 sf) rolls cover over 30% more area than other products and are installed like standard geotextiles. With no nets to tie together and using normal geotextile seaming methods, installation becomes very easy. Technical Specification: Physical & Mechanical Properties of Integrated Drainage Composite and Testing values to achieve its classification mentioned below: 1. Mass per unit area is 506 g/m2 2. Thickness is 4.5 under 2 kPa 3. Tensile strength is 7.4 kN/m 4. Tensile elongation is 60 % 5. Pyramidal puncture resistance is 1.4 kN 6. Dynamic perforation resistance is 12^ mm 7. CBR resistance is 2.6 kN 8. Mini-pipe Diameter is 19.6 mm 9. Mini-pipe stiffness at 5% deflection is 4000 kPa 10.Apparent Opening size is 200^ m 11. Water permeability is 0.07 m/s 12.In plane flow capacity | 4978.00 | sqm |
| 4 | MES Revetment is a pre-engineered factory custom grouted mattress system used for permanent erosion protection works. Depending upon project requirements, design considerations and specific application, the type of fabric form is designed and pre-fabricated at the factory and delivered to job sites. This technology is used to protect embankments (dry or wet), protect bridge abutments against scour, and used for flood bank and bed protection of major rivers and waterways, lining of canals and for mining and industrial erosion protection and lining applications. This system can be installed at rapid speed and and also under water without the need for dewatering. MES Revetment is an alternative and durable solution for erosion protection with flexible concrete block. High strength woven Geotextile made from polyester yarn is used to provide the shape and form. Essential components of TechRevetment are non-woven geotextile filter, woven geotextile fabric form and fine aggregate concrete. Depending upon the design requirement and specific application, the type of fabric form to be used is chosen.TechRevetment Filter Point linings with filtration point (drains) provide an erosion resistant, permeable concrete lining having a cobbled surface and a relatively high coefficient of hydraulic friction in order to reduce water velocity and wave run-up. The spacing of the filter points determines the linings thickness and weight, while the specially designed filter points relieve hydrostatic pressure and reduce applied stress to the fabric form during pumping. Technical Specification: Physical & Mechanical Properties of MSE Revetment and Testing values to achieve its classification mentioned below: 1. Mass Per Unit Area (single-layer) as per ASTM D 5261 >200 g/m2 2. Mass Per Unit Area (double-layer) as per ASTM D 5261 is >400 g/m2 3. Thickness (single-layer) as per ASTM D 5199 is 0.35 mm 4. Mill Width (Woven) is 3.00 m 5. Wide Width Tensile Strength as per ASTM D 4595 is 50 kN/m 6. Wide Width Elongation at Break is 10 % 7. Trapezoidal Tear Strength as per ASTM D 4533 is 350 N 8. CBR Puncture Strength as per ASTM D 6241 is 5100 N 9. Apparent Opening Size (AOS) as per is <0.8 ASTM D 4751 mm 10. Water Flow Rate as per ASTM D 4491 is >1000 l/m2/min | 4978.00 | sqm |
| 5 | Supply of Vertical pressure sustainer of 2 MT capacity 500FT 1 D20 is an active anchoring system used for permanent as well as temporary stabilisation of existing slopesand structures by using high tensile steel soil anchors (galvanized bar or strands). This is a driven and stressed soil anchoring system used with a suitable facing. Unlike other slope stabilisation methods, this system does not require heavy equipment and cement (grout), thus making it a practical solution, without the need for heavy working platforms and large work space. Technical Specification: Physical & Mechanical Properties of Vertical Pressure sustainer and Testing values to achieve its classification mentioned below: Anchor Head :- Material is S.G. Iron casting (Grade 500/7) confirming to IS 1865:1991 Length 160 mm Width 57 mm Height 50 mm Anchor Bar :- Grade EN18 as per BS 970 Tensile Strength 700 N/mm2 Yeild strength 500 N/mm2 Elongation 12 % Anchor Strand :- Material Galvanised Steel Core Construction of Strand Steel core 6 x 36 Diameter of Wire 8 mm Tensile Strength 1770 kN/m2 Minimum Breaking Force 41kN Working Load 27 kN Bearing Base Plate :- Dimension 200 x 200 mm & Thickness 10 mm Tensile Strength 500 N/mm2 Yeild strength 450 N/mm2 | 120.00 | Nos |
