Deep foundation pit anti-floating anchor cable post-water-proof construction method
The invention particularly relates to a deep foundation pit anti-floating anchor cable post-water-proof construction method. The method comprises the steps of performing drilling through a down-the-hole drill; mounting anchor cables; grouting anchor cable anchorage sections; using metal bellows as extension bushings; performing water-proof processing on the peripheries of the metal bellows, wherein the thicknesses of the metal bellows buried in cushion layers are not less than 20 centimeters; pouring concrete cushion layers; binding bottom plate reinforcing ribs and fixing the metal bellows with the bottom plate reinforcing ribs; mounting anchor cushioning plates, concreting bottom plates and reserving anchor cable pits; mounting anchor tools and performing anchor cable pre-stress tensioning; performing anchor cable free section grouting after anchor cable tensioning; cutting redundant steel strands at the tops of the anchor cables; mounting grouting tubes, performing grouting from grouting holes and concreting anchor cable pit; performing polyurethane pressure injection from water check needle tubes. By the aid of the method, the construction method is simple, construction materials can be obtained easily, a multi-water-proof technology is used, and the problems of water seepage and water leakage of anti-floating anchor cables can be prevented effectively.
