Bonded post-tensioned prestressed anchoring construction method for cast-in-place concrete structure

The invention discloses a bonded post-tensioned prestressed anchoring construction method for a cast-in-place concrete structure. The method comprises the following steps of: manufacturing and placing a steel bar cage, a steel conduit end check valve and cast-in-place concrete to form an underground structure, descending a prestressed steel strand to a design connecting part after the underground structure is molded and reaches the age, and tensioning the steel strand, anchoring and relaxing an end and grouting in a steel conduit by using special equipment, so that a prestressed steel bar is protected, and bonded connection is realized. The problem that a pile and an underground continuous wall bear buoyant force and horizontal force is solved; for the underground continuous wall which bears high bending moment, the problem that the wall on the side with higher bending moment is cracked is solved; steel is saved, the structure is easy and convenient to construct, environment is not polluted, the working surface and the construction period are not influenced, the quality guarantee rate is high, and the prestressed steel strand is inserted in a short time when the concrete is poured; and a bonded prestress applying mode is realized, the prestressed steel strand can be protected, and the durability of the underground structure is guaranteed.
