Project Name: Afarinesh Tower Soil Improvement – Ramsar City
Group: Jet Grouting
Owner: Dr. Malekshahi
Consultant: Zamiran Co.
Duration: 3 months
Method: 9000 m Jet Grouting columns with 800 and 900 mm diameter
Explanation: To increase bearing capacity, settlement control and liquefaction mitigation of 25-floor Afarinesh tower foundation, 1200 jet grouting columns with 80 to 90 cm diameter and 7.5 m depth with compression strength of 100 tons each were designed for 4000 m2 as an alternative to cast-in-situ piles which caused to increase the safety factor of liquefaction mitigation to 1.5. 30% cost reduction and 50 % time saving were achieved by using jet grouting instead of cast-in-situ piles. PIT and static tests results were satisfactory by Zamiran Consulting Engineers Company.
