Abstract

The invention discloses a self-stabilizing fast-connect wall steel formwork for construction of super-large-diameter engineering piles, which comprises: a steel formwork surface, the horizontal section of which is arc-shaped; the steel formwork surface is used for pouring concrete One side is the outer side, and the other side is the inner side; side frames, the side frames are welded to the two sides of the steel formwork surface; stiffeners, the stiffeners are welded to the inner side of the steel formwork surface; different The stiffeners are arranged parallel to each other; the template connector is used to connect the adjacent wall steel templates through the side frames. The self-stabilizing quick-connect wall steel formwork used for the construction of super-large-diameter engineering piles of the present invention is simple in splicing and fast in construction speed. In addition, because the retaining steel formwork is made of metal with strong wear resistance and strength, it has a longer service life than wooden formwork and can be used more times.

Description

technical field [0001] The invention belongs to the technical field of engineering pile construction, and in particular relates to a self-stabilizing fast-connecting steel formwork for retaining walls used in the construction of super-large-diameter engineering piles. Background technique [0002] Manual digging piles refer to reinforced concrete piles that are excavated by manpower and poured on site. Manually dug piles are generally thicker in diameter, and the thinnest is more than 800 mm, and are currently widely used. Manual digging piles are easy to construct, fast, and do not require large-scale mechanical equipment. Digging piles are stronger in earthquake resistance than wooden piles and concrete driven piles. Rotary drilling rig drilling, caisson foundation saving. Therefore, it is widely used in roads and civil buildings. However, the underground operation conditions of excavated piles are poor, the environment is harsh, and the labor intensity is high, so safe...
