The invention relates to the technical field of constructional engineering, in particular to a soft foundation building foundation structure. According to the technical scheme, the structure comprises a plurality of pipe piles, rigid grouting pipes are arranged in the middles of the pipe piles, and the rigid grouting pipes are circumferentially connected with a plurality of sleeves; one end of the sleeve communicates with the interior of the rigid grouting pipe, the other end of the sleeve is fixedly connected with the side wall of the pipe pile, and a soil inserting rod is inserted into the sleeve; a piston ring is fixed outside the inner end of the soil inserting rod, the soil inserting rod and the piston ring can move in the sleeve in the direction away from the grouting pipe, and a plurality of grouting holes are formed in the side wall of the soil inserting rod. A slidable guide rod is arranged in the soil inserting rod in a matched mode, the inner end of the guide rod is fixedly connected with the rigid grouting pipe, and the length of the portion, inserted into the soil inserting rod, of the guide rod is smaller than the movable stroke of the soil inserting rod in the sleeve. The structural strength of the soft foundation and the bearing capacity of the foundation can be improved, the pipe piles and the foundation are connected to form soil piles, and therefore the sinking amount of the foundation piles and a building structure is reduced, and the safety of the building structure is ensured.
本发明涉及建筑工程技术领域，具体涉及一种软地基建筑基础结构；采用的技术方案是：包括多根管桩，管桩中部设有刚性注浆管，刚性注浆管周向连接有多个套筒；套筒一端与刚性注浆管内部连通，套筒一端与管桩侧壁固定连接，套筒内插设有插土杆；插土杆内端外固定有活塞环，插土杆和活塞环可向远离注浆管的方向在套筒内移动，插土杆侧壁设置有多个注浆孔；插土杆内适配有可滑动的导向杆，导向杆内端与刚性注浆管固定连接，导向杆插设在插土杆内的长度小于插土杆在套筒内可移动的行程。本发明能够增加软地基的结构强度和提高地基的承载能力，并使管桩与地基连接成土体桩，从而减小基桩和建筑构体的下沉量，确保建筑结构安全。
