Abstract

The invention discloses a prefabricated pressed-in underground continuous wall, which comprises a side baffle, a compression bar is installed on one side of the side baffle, a ground breaker is installed at the bottom of the side baffle, and the side baffle Side ears are installed on the top of the plate, a connecting plate is installed on the other side of the side baffle, and screw heads are installed at both ends of the telescopic plate. The continuous wall of the present invention is equipped with side baffles, a connecting plate is installed on the inner side of the side baffles by welding, side ears are installed on the top of the side baffles, and pressure-resistant plates are installed on the top of the side ears, through which it is convenient to install Hammering is performed to increase its anti-strike ability. A ground breaking head is installed at the bottom of the side baffle, through which it is convenient to press the continuous wall in and easy to install and disassemble. An expansion plate is installed between the connecting plates, and the two ends of the expansion plate are The screw head is installed, and the expansion plate is installed in the expansion sleeve, and the width of the continuous wall can be adjusted through the expansion plate, which increases the versatility.

Description

technical field [0001] The invention relates to the field of continuous walls, in particular to a prefabricated pressed-in underground continuous wall. Background technique [0002] The continuous wall is a continuous wall constructed by using drilling equipment to form a groove section. It 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, saving The construction cost is simplified, the construction procedure is simplified, the functions are diverse, and the construction pollution is small. Diaphragm walls are currently widely used in the construction of underground parking garages and subway construction in China. [0003] There are many deficiencies in the diaphragm wall at the present stage, for example, it is inconvenient to install and disassemble, and the universal performance is poor. Contents of the invention [0004] The obje...
