The invention relates to a combined foundation pit support beam string structure comprising a concrete beam, a support prestress device and a tensile device. A steel purlin is not arranged on the inner side of the concrete beam, and an end pull rod of the beam string structure is pre-buried and fixed in the concrete beam; the support prestress device directly or indirectly acts on the part, corresponding to the end pull rod, of the concrete beam; the support prestress device is not rigidly connected with the end pull rod; the tensile device comprises a metal piece pre-buried in the concrete beam in a foundation pit, and a prestress regulating device is connected with a prestress connecting piece; and the prestress connecting piece is connected with the part, extending out of the concrete beam, of the metal piece. According to the beam string structure, a truss support system and a beam string structure support system are separately independent, so that the truss support system and thebeam string structure support system are installed and constructed separately in the construction process, and further operated during removal separately; the construction period is shortened, and theconstruction flexibility is improved.
本发明涉及一种组合型基坑支撑张弦梁，包括：混凝土梁，所述混凝土梁内侧不设置钢围檩，张弦梁的端部拉杆预埋固定在所述混凝土梁中；直接或间接作用于与端部拉杆对应部位的混凝土梁上的支撑预应力装置；所述支撑预应力装置与端部拉杆不刚性连接；抗拉装置，所述抗拉装置包括基坑内的混凝土梁内预埋的金属件，预应力调节装置与预应力连接件连接，预应力连接件与所述金属件伸出所述混凝土梁的部位连接。本发明使桁架支撑系统与张弦梁支撑系统之间各自独立，从而在施工过程中可以单独安装施工，拆除时也可单独作业，缩短施工工期，提升施工灵活性。
