Embodiment Construction

[0022] Referring to the accompanying drawings, a recyclable foundation pit enclosure structure with lifting holes includes a first board 1 and a second board 2 arranged vertically, and the first board 1 and the second board 2 The inner cavities are vertically connected, so that the soil can enter the inner cavities of the first plate body 1 and the second plate body 2 during the process of pressing into the soil body;

[0023] The left and right sides of the first plate body 1 are inwardly recessed to form a first groove 11, and the left and right sides of the second plate body 2 have first protrusions 21 protruding outward. The first plate body 1 and the second plate body 2 Realize detachable connection through the first groove 11 and the first protruding head 21;

[0024] The left and right sides of the first plate body 1 are provided with first screw holes 4, the left and right sides of the second plate body 2 are provided with second screw holes 5, the first screw holes 4 ...

Abstract

Provided is a recoverable foundation pit support structure with pull-out holes. An inner cavity of a first plate and an inner cavity of a second plate are through in the vertical direction. The left side and the right side of the first plate are concave inwards to form first grooves. The left side and the right side of the second plate are provided with first convex heads protruding outwards. The first plate and the second plate are detachably connected through the first grooves and the first convex heads. The front vertical face and the rear vertical face of the first plate and the front vertical face and the rear vertical face of the second late are provided with the through pull-out holes. The adjacent plates are connected through concave-convex embedment and are further reinforced through bolt connection, and support strength is high. By means of convex-concave embedment connection, the overall seepage prevention of the structure is high, and obvious seams do not occur. The structure can be applicable to most foundation pit projects, is good in applicability and high in integrity. The plates can be recycled, cost of foundation pit support is greatly reduced, and the structure is low in carbon and environmentally friendly.

Description

technical field [0001] The invention relates to a recoverable foundation pit enclosure structure with lifting holes. 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 overall stiffness o...
