The invention discloses a connecting device for new and old underground continuous walls, which comprises a connecting plate main body, a bendable structure is installed in the middle of the connecting plate main body, and mounting plates are installed at both ends of the connecting plate main body. One end of the mounting plate is equipped with a connector, the two ends of the connector are respectively equipped with a first screw head and a second screw head, the two sides of the connector are equipped with a connecting frame through a hinge, and one end of the connecting frame is installed With fixed ears. The middle part of the connecting plate main body of the present invention is equipped with a bendable structure, and the connecting plate main body can be bent into a radian through the bendable structure, so that the connecting plate main body can be connected between the connecting walls of the arc-shaped structure, increasing its versatility , and the two ends of the main body of the connecting plate are installed with a mounting plate of an integral structure, the installation of the connecting head is facilitated through the mounting plate, and the first screw head and the second screw head are respectively installed at both ends of the connecting head, through which the device is convenient Installation and disassembly.
Description
technical field [0001] The invention relates to the field of connection devices, in particular to a connection device for new and old underground continuous walls. Background technique [0002] The connecting device of the new and old underground diaphragm walls is used to connect and fix the new and old underground diaphragm walls. The diaphragm wall is a continuous wall constructed by using drilling equipment to form a groove section. The continuous wall constructed has a large structural rigidity and can play a good supporting role. It is suitable for various geological conditions and can be used as a part of the main body of the underground building, which saves the project cost and simplifies the construction procedure. The pollution is small. [0003] A connection device for new and old underground diaphragm walls at the present stage has many deficiencies, for example, it is inconvenient to install and disassemble, and the stability of the fixation is poor, the gener...
