Cold region fabricated concrete bearing platform and micro pile combined foundation
The invention discloses a cold region fabricated concrete bearing platform and micro pile combined foundation, and belongs to the technical field of cold region foundation engineering and structural engineering. Fabricated column components which are vertically stacked and clamped are provided with hollow cavities for pouring self-compacting concrete and are connected with a bearing platform bottom plate through prestressed steel bars, cross-shaped connecting bases connected with the bearing platform bottom plate are arranged on the outer sides of the fabricated column components, assembly part splicing steel plates are arranged outside the bearing platform bottom plate in a surrounding mode, and steel reinforcement cages are arranged in the assembly part splicing steel plates; the steel reinforcement cages are connected to the cross-shaped connecting bases, and a bearing platform upper cover plate is arranged at the upper ends of the steel reinforcement cages; and the cross-shaped connecting bases are connected with the assembly part splicing steel plates through connecting steel bars. Foundation treatment, use of large-diameter cast-in-place piles and engineering cost are reduced, the problem of large-volume overall concrete pouring in the deep and thick muddy soil area in the cold region is solved, the invention is not limited by environment temperature, geological environment, concrete hydration reaction and construction site, the overall bearing capacity, rigidity, crack resistance and service performance of concrete are improved, and the cost and the use of materials are saved.
一种寒区装配式混凝土承台与微型桩联合基础，属于寒区基础工程和结构工程技术领域。上下叠放卡接的装配式柱构件有浇注自密实混凝土的中空腔，通过预应力钢筋与承台底板连接，装配式柱构件外侧有与承台底板连接的十字连接座，承台底板外有围合设置的装配件拼接钢板，装配件拼接钢板内有钢筋笼，钢筋笼与十字连接座连接并上端有承台上盖板；十字连接座通过连接钢筋与装配件拼接钢板连接。本发明减少了地基处理、大直径灌注桩的使用以及工程造价，避免了寒区深厚淤泥质土地区混凝土大体积整体浇筑的问题，不受环境温度、地质环境、混凝土水化反应、施工场地限制，提高了混凝土整体承载力、刚度、抗裂性能、服役性能，节约成本和材料的使用。
