Abstract

The invention provides a foundation pit support structure with screw holes and a pyramid-shaped bottom. A first plate and a second plate are provided with inner cavities, the top face of the first plate and the top face of the second plate are opened, and the bottom face of the first plate and the bottom face of the second plate are sealed; the bottom of the first plate and the bottom of the second plate are both in a pyramid shape; the left side and the right side of the first plate are concaved inwards to form first grooves, first protruding heads protruding outwards are arranged on the left side and the right side of the second plate, and the first plate and the second plate are detachably connected through the first grooves and the first protruding heads. First screw holes are formed in the left aide and the right side of the first plate, second screw holes are formed in the left side and the right side of the second plate, the first screw holes and the second screw holes are horizontally through, and bolts penetrate through the first screw holes and the second screw holes to fasten the first plate and the second plate together.

Description

technical field [0001] The invention relates to a foundation pit enclosure structure with screw holes and a pyramid-shaped bottom. Background technique [0002] With the continuous development of underground space, in order to facilitate construction, the depth requirements of foundation pits are also getting higher and higher. The excavation of the foundation pit usually requires some enclosure structures to improve the overall stability of the foundation pit. [0003] The Chinese patent with the publication number CN202559363U discloses a steel structure underground diaphragm wall foundation pit support structure, which consists of several H-shaped steel piles arranged in parallel to each other through the front row of steel sheet piles and the rear row of steel sheet piles. The soil between the piles is formed between the steel sheet piles, the rear row of steel sheet piles, and the H-shaped steel between two adjacent piles. Although the invention can increase the overa...
