ZHU WENWEI / YANG XUELIN / WANG LIHU / ZHOU HAOYI / YUE YANLING

The invention discloses a servo concrete and steel supporting system for actively controlling deformation of a foundation pit. The servo concrete and steel supporting system for actively controlling deformation of the foundation pit can effectively control deformation of the foundation pit. The structure comprises a peripheral purlin beam which is fixed on the inner wall of a foundation pit enclosure wall; the inner enclosing purlin beam is positioned on the inner side of the outer enclosing purlin beam; the transfer beam is positioned on the inner side of the inner enclosing purlin beam; the reinforcing plate strip is located between the inner enclosing purlin beam and the transfer beam, and the inner enclosing purlin beam and the transfer beam are connected into a whole through the reinforcing plate strip; the steel supports are located on the inner sides of the transfer beams and supported between the transfer beams; the servo loading devices are sequentially distributed along the peripheral purlin beam, the servo loading devices are located between the inner enclosing purlin beam and the peripheral purlin beam, and the servo loading devices are used for opening the inner enclosing purlin beam and the peripheral purlin beam.

本发明公开了一种用于主动控制基坑变形的伺服混凝土与钢支撑体系，旨在提供一种能够有效控制基坑变形的用于主动控制基坑变形的伺服混凝土与钢支撑体系。它包括：外围檩梁，外围檩梁固定在基坑围护墙的内壁上；内围檩梁，内围檩梁位于外围檩梁的内侧；转换梁，转换梁位于内围檩梁的内侧；加强板带，加强板带位于内围檩梁与转换梁之间，且加强板带将内围檩梁与转换梁连为一体；钢支撑，钢支撑位于转换梁内侧并支撑在转换梁之间；若干伺服加载装置，各伺服加载装置沿外围檩梁依次分布，且伺服加载装置位于内围檩梁与外围檩梁之间，伺服加载装置用于撑开内围檩梁与外围檩梁。
