Fabricated building foundation structure for frozen soil construction
A frozen soil construction assembly type building foundation structure relates to a building foundation structure on frozen soil and is characterized in that a plurality of channel steels (16) are arranged on the periphery of a barrel (15), and a U-shaped pipe (11) is arranged on the outer surface of the barrel between every two channel steels; a foundation pit (19) is excavated on the frozen earth surface (12), cast-in-place concrete (21) is poured into the bottom of the foundation pit, a concrete precast pile (14) is placed into the foundation pit and sleeved with a cavity (25) of a lower barrel of an end plate (1), the barrel is filled with soil for digging, and backfill soil (17) is tamped; adjusting rings (7) sleeved on a plurality of steel channels are tightly connected with the ground surface through puller screws (6); one of the two upper pipe orifices of the U-shaped pipe is connected with a cold air inlet, and the other is an air outlet; the height adjusting screw for adjusting the height of the end plate is arranged on the upper plate of the cylinder body to overcome the defect of settlement adjustment of a single foundation pile, and instability caused by ground surface settlement is adjusted by controlling the height of the adjusting ring through the puller screw.
一种冻土施工装配式建筑基础结构，涉及一种冻土上的建筑基础结构，筒体（15）四周设有多根槽钢（16），两两槽钢之间的筒体外部面上设有U形管（11）；在冻土地表（12）开挖出基坑（19）并在基坑底部灌入现浇混凝土（21），将混凝土预制桩（14）放入基坑，将端板（1）下部筒体的腔体（25）套在混凝土预制桩上，使用挖坑的土填入筒体并夯实回填土（17）；套在多根槽钢的调节环（7）使用顶紧螺丝（6）使调节环的下部面与地表紧密连接；U形管的两上管口一个连接冷风送入，另一个为排风口；本发明在筒体的上部板上设置调节端板高度的调高螺丝来克服单根基础桩的沉降调节，由顶紧螺丝控制调节环的高低来调节地表沉降带来的不稳定。
