Optimal Injection Method In Divresion Structures Of Earth Dam

Pressurized injection operation means the pressurized injection of a liquid or solution into pore of a mass of soil or stone and/ or cavity between them and built structures. The injected mortar mustconstitute a soil and/ or jel- like matter inside the cavites, and/ or the operations of the injection must cause sedimentation of the solid matter suspending in these cavites. The primary purpose of the pressurized injection of soil or stone masses is to increase the resistance and durability of these masses and/ or decreae their permibility. In this paper, the optimal pressurized injection has been presented for the improvement of the areas are not in good conditions in terms of substructure, and necessary instructions have been menitioned o prevent such substructure problems. In this research, the injection method of diversion structures in Berenjestank culvert earth dam has been specified, and its specification have been mentioned.
