The invention discloses a prestressed combined string truss applied to foundation pit engineering. The prestressed combined string truss comprises a surrounding purlin, a pull rod; an inhaul cable; web members; an anchor socket; a multi-hinge node; the enclosing purlins, the pull rods, the inhaul cables, the web members, the anchor seats and the multi-hinge joints are combined to form a parabolic truss. The enclosing purlin is used for bearing pressure generated by a truss, the multiple web members are vertically fixed to the enclosing purlin, and the lengths of the web members are sequentially reduced from the middle of the enclosing purlin to the two sides of the enclosing purlin; the plurality of pull rods are respectively connected with the end parts of the web members; the multi-hinge joints are arranged at the connecting positions of the pull rods and the web members, and the pull rods are rotationally connected with the web members through the multi-hinge joints; the anchor seats connected with the ends of the pull rods on the two sides are arranged on the two sides of the enclosing purlin, and the inhaul cables and the pull rods are used in a combined mode to achieve the effect of bearing the pulling force of a truss. And a transverse tensioning device is arranged between the inhaul cables.
本发明公开了一种运用于基坑工程的预应力组合张弦桁架包括围檩；拉杆；拉索；腹杆；锚座；多铰节点；所述围檩、所述拉杆、所述拉索、所述腹杆、所述锚座和所述多铰节点组合形成一抛物线形桁架；所述围檩用于承受桁架产生的压力，所述腹杆设有多根，多根所述腹杆与所述围檩垂直固定，所述腹杆的长度由所述围檩的中间向两侧依次减小；所述拉杆设有多根，所述拉杆分别连接所述腹杆的端部；所述拉杆和所述腹杆的连接位置设有所述多铰节点，所述拉杆通过所述多铰节点与所述腹杆转动连接；所述围檩的两侧设有与两侧的所述拉杆的端部连接的所述锚座，所述拉索与所述拉杆组合使用均起到了承受桁架拉力的作用；所述拉索之间设有横向张拉装置。
