Drain Lining Work

Location: – Kota, Rajasthan
Client Name: – Subhash Infra Engineers Pvt Ltd. Kota
Year of construction:- May 2022

Problem: – Railway track line was proposed in between Kota-Bina Junction, and the contract was given to Subhash Infra engineers Pvt. Ltd. by Rail Vikas Nigam Limited on tender basis. Earlier, traditional concreting was to be done but it was taking about two months for overall preparation and readiness with shuttering, concrete pouring, curing etc.
Solution: – Concrete Impregnated Carpet was used due to ease of installation and its effectiveness against weathering and rainy season water flow cases. Works to be in position to channelize water. But as the rainy season was at the door they needed fastest installation so they moved to concrete canvas and completed the work within a span of one week. The profile of the drain including excavation and preparation was done by the SSPL and installation of CIC was carried. On an average of 10 labours per day were applied under supervision of site engineer. The patches of the CIC were joined with thermal welding to prevent the ingress of water and air from the joints. The description of the work is stepwise illustrated in the photos given below. Proper hydration of the installed patches was done to achieve maximum strength, generally half the weight of the CIC is preferred for hydration.
