Special construction method for basement foundation through steel structure alternate construction
The invention discloses a special construction method for a basement foundation through steel structure alternate construction. The method is characterized in that a steel structure bearing platform and a steel plate wall core tube foundation are subjected to pouring in a staggered three-layer mode; at the first layer, a supporting frame of a steel plate wall positioner and a supporting frame of asteel pipe column positioner are pre-buried, and pouring is conducted from a bearing platform cushion layer to the position of a lower opening of a cross-shaped positioning steel plate; at the secondlayer, a steel plate wall and a steel pipe column are embedded and fixed, fixing is conducted through the positioners, and secondary-layer pouring is conducted to a bottom elevation of an integral bottom plate foundation; at the third layer, large-area one-time pouring and tamping are conducted on concrete of a basement integral bottom plate foundation; and inner and outer water stop rings are arranged on the steel pipe column, and a water stop steel plate is arranged on the steel plate wall. According to the construction method, the construction is convenient, accurate overall positioning onthe steel plate wall and the steel plate column is guaranteed, the overall stability of the bearing platform is guaranteed, and the common problem of water seepage of a bearing platform in traditional construction is solved.
一种钢结构穿插施工地下室基础特殊施工方法，其方法在于，钢结构承台与钢板墙核心筒基础错开三层浇筑，第一层为钢板墙定位器与钢管柱定位器的支撑架预埋施工，浇筑自承台垫层往上至十字定位钢板下口的位置；第二层为钢板墙与钢管柱嵌固定施工，采用定位器进行固定，第二层浇筑至整体底板基础底标高；第三层待地下室整体底板基础混凝土大面积一次性浇捣；在钢管柱上设置内外止水环，在钢板墙上设置止水钢板；本发明的施工方法方便施工，确保钢板墙与钢板柱整体定位准确，保证了承台的整体稳定性，并克服了传统施工中承台渗水的通病。
