Example Embodiment
[0037] The present invention will be further described below in conjunction with the drawings and specific embodiments, but not as a limitation to the present invention.
[0038] A construction method of prestressed concrete basement with and without bonding, according to the following steps:
[0039] a) Closely combine the pile body and the plain concrete cushion, and separate the pile body from the basement floor; when the bearing capacity of the ground cannot be satisfied, the pile foundation is used, and the pile foundation and cushion are closely combined. But the pile body is separated from the bottom plate;
[0040] b) A plastic plate sliding layer is set between the plain concrete cushion and the basement floor. The plastic plate is preferably a material with a low friction coefficient;
[0041] c) Stretch the steel strands in two horizontal directions of the basement floor to apply prestress;
[0042] d) Do a good job of waterproofing between the pile body and the basemen...
