Steel pipe underpinning device for replacing support replacement in deep foundation pit
The invention discloses a steel pipe underpinning device for replacing support replacement in a deep foundation pit, and relates to the technical field of steel pipe underpinning. According to the technical scheme, the steel pipe underpinning device comprises a supporting rod, wherein threaded sleeves are connected to the two ends of the supporting rod through threads, supporting pipe bodies are arranged on the outer sides of the threaded sleeves, and a plurality of limiting structures are rotationally arranged on the outer sides of the supporting pipe bodies; connecting blocks penetrating through the supporting pipe bodies are arranged on the outer circumferential faces of the threaded sleeves, and limiting blocks are fixed to the other ends of the connecting blocks; and hinge seats are fixed to the ends, away from each other, of the supporting pipe bodies, mounting plates are rotationally arranged on the other sides of the hinge seats, and preformed holes are formed in the four corners of each mounting plate. According to the steel pipe underpinning device for replacing support replacement in the deep foundation pit, the extension length of the device can be adjusted, supporting force expanding towards the two sides is generated, therefore the underpinning environment is created, meanwhile, the use limitation is reduced, operation is easy, and use is convenient.
本发明公开了一种深基坑内取代换撑的钢管托换装置，涉及钢管托换技术领域。现提出以下技术方案：其包括支撑杆，所述支撑杆的两端均通过螺纹连接有螺纹套筒，所述螺纹套筒的外侧均设置有支撑管体，所述支撑管体外侧转动安装有多个限位结构，所述螺纹套筒外圆周面设置有贯穿支撑管体的连接块，连接块的另一端均固定有限位块；所述支撑管体相互远离的一端均固定有铰接座，所述铰接座的另一侧均转动安装有安装板，安装板的四角处均设置有预留孔。本发明可以使得装置的延伸长度得以调节，并产生向两侧扩展的支撑力，从而实现创造托换的环境，同时降低了使用的局限性，操作简单，使用方便。
