Execute i -shaped assembled enclosure fast has solved the long and technical problem serious to the environmental impact of assembled enclosure pile foundation construction cycle, and the technical scheme of adoption is: include the foundation pile in the structure, fix anti -wind post and the location combination wall body between adjacent anti -wind post on the foundation pile, the foundation pile is the steel -pipe pile, and including the steel pipe in the structure, set up at the footstock on steel pipe top and set up the spacing pterygoid lamina at the steel pipe lateral wall, grafting that the combination wall body passed anti -wind post both sides is from top to bottom in proper order erected and is pegged graft spacingly with spacing pterygoid lamina after the groove is erected to location on the footstock of groove and steel pipe. The beneficial effects of the utility model are that: simple structure is firm in the combination, construction convenience, and do not receive weather effect, all can construct under any weather condition, can not former therefore influence the construction progress because of weather, worker labor intensity is low in the construction, owing to adopted the fiber cement wallboard, matter is gently inexpensive simultaneously, very big reduction the input cost of equipment, manpower.
