With rapid development of the city, demands for civil air defense, underground commercial and underground parking in human society have increased. Development of the construction space towards the underground is enhanced, and foundation pit excavation is widely used. Bore pile + anchor cable supporting model has been used more and more in deep foundation pit supporting. Based on engineering examples, this essay expounds the construction scheme of deep foundation pit support for a residential area project, introduces the construction technology of bore pile, crown beam and waist beam, and analyzes in detail the construction technology of the installation, grouting and tension anchoring of anchor cable in prestressed anchor cable construction. The quality control points in the construction are discussed and summarized in depth, which could provide powerful reference for the implementation of civil engineering construction tasks and ensure smooth progress of the project to achieve the expected results.
