WANG WENGUANG / CHEN LIU / QIU YIPING / CHEN DINGFENG / CHEN YANG

The invention relates to the technical field of municipal engineering equipment, in particular to an assembly type fixing device for municipal engineering drainage open channel construction, and adopts the technical scheme that the assembly type fixing device comprises a drainage open channel, slopes are arranged at the two ends of the top of the drainage open channel, and net hanging sprayed concrete layers are constructed; larsen steel sheet piles are evenly installed in the numerical direction of the inner wall of the drainage open channel through a pile driver, and the I-shaped steel is welded to the Larsen steel sheet piles and is horizontally arranged in the transverse direction. The two ends of the supporting plate device are installed on the I-shaped steel through positioning connecting pieces, and the supporting plate device supports the I-shaped steel at the two ends in an arched mode through an arc-shaped metal plate structure. Two ends of the spring steel I are arched to support two ends of the Larsen steel sheet pile, and sufficient supporting force is provided.

本发明涉及市政工程设备技术领域，具体涉及一种市政工程排水明渠施工用组装式固定装置，其技术方案是：包括排水明渠，所述排水明渠顶部两端设置为斜坡，并施工成挂网喷射混凝土层，所述排水明渠内壁数值方向通过打桩机安装均匀安装拉森钢板桩，还包括焊接在拉森钢板桩上的工字钢，且工字钢横向水平设置；支撑板装置，所述支撑板装置两端通过定位连接件安装在工字钢上，支撑板装置通过弧形的金属板结构对两端的工字钢进行拱形支撑，本发明的有益效果是：通过旋转螺杆上的螺母抵住弹簧钢一，并将两组弹簧钢一向外撑开；通过弹簧钢一两端呈拱形状态支撑拉森钢板桩两端，提供充足的支撑力。
