Internal support structure for diaphragm walls

Abstract

In the field of wall support technology, we provide an internal support structure for diaphragm walls. [Solution] The structure comprises a support column 1, a flange plate 2, and a base plate 3. The flange plate is fixedly connected to both sides of the outer wall of the support column, and the base plate is connected to one side of the outer wall of the flange plate. A vertical column 4 is provided on one side of the middle of the support column, and a positioning groove 5 is opened inside the vertical column. Support seats 6 are connected to both sides of the middle of the vertical column, and support supports are connected to both sides of the top end of the support seat. A stopper seat is welded to the top end of the outer wall of the support support, and a stopper member is connected to one side of the bottom end of the stopper seat. An extension seat is fixedly connected to the middle of the outer wall of the support seat, and an engaging member is fixedly connected to one side of the outer wall of the extension seat. The internal support structure of the underground continuous wall of this invention ensures installation accuracy with the cross-shaped positioning groove of the vertical column, and the I-shaped connected support seats and C-shaped support supports form a rigid vertical support unit, thereby improving lateral displacement resistance.
