Double-steel-plate temporary supporting device for unbalanced foundation pit
The invention relates to a foundation pit supporting device, in particular to an unbalanced foundation pit double-steel-plate temporary supporting device which comprises double-steel-plate connecting units, the foundation pit temporary supporting device is formed by alternately connecting the double-steel-plate connecting units in the length direction, and each double-steel-plate connecting unit comprises a narrow double-steel-plate buckling pile and a wide double-steel-plate buckling pile. The narrow double-steel-plate buckling pile comprises a pair of first steel plate pile and second steel plate pile which are symmetrically attached, and the wide double-steel-plate buckling pile comprises a pair of third steel plate pile and fourth steel plate pile which are symmetrically spaced. The double-row steel plate pile connecting units are connected in sequence, the problem that displacement of a single row is too large due to the fact that rigidity of pile bodies is too small is solved, a supporting system with large rigidity is formed through the double-row steel plates and the soil layer between the double-row steel plates, and the overall supporting rigidity is good.
本发明涉及基坑支护装置，具体涉及一种不平衡基坑双钢板临时支护装置，包括双钢板连接单元，基坑临时支护装置由所述双钢板连接单元沿长度方向交替连接而成，所述双钢板连接单元包括窄型双钢板扣接桩和宽型双钢板扣接桩，所述窄型双钢板扣接桩包括一对贴合对称的第一钢板桩和第二钢板桩，所述宽型双钢板扣接桩包括一对间隔对称的第三钢板桩和第四钢板桩。本发明采用双排钢板桩连接单元依次连接，减少单排因桩体本身刚度过小而造成位移过大等问题，通过双排钢板与其之间的土层形成刚度较大的支撑体系，整体支撑刚度好。
