Single-arm steel hanging box and construction method thereof

Abstract

The invention relates to a single wall steel hanging case, pertaining to a deep water platform and pier column construction enclosure structure. The invention also relates to a construction method for a single wall steel hanging case. The invented single wall steel hanging case mainly comprises a side plate and a bottom plate, wherein the side plate is mainly composed of an upper segment and a lower segment, and the bottom plate comprises a panel, a longitudinal beam and a transverse beam, wherein the panel is paved on the longitudinal beam, the edge of the panel parallel to the longitudinal beam is welded with an equal angle steel, the other two edges are welded with a steel angle flange, and a nut is welded correspondingly at the lower side of the steel angle flange through hole; the longitudinal beam is paved on the transverse beam, each two beams are disposed at the two sides of the hole, each end of the beam is welded with a anchor backing board, and a through hole is disposed at the inner and outer two sides of the anchor backing board corresponding to the side plate. The bottom of the invented single wall hanging case is removable, and the shortcoming of the traditional steel hanging case that the bottom plate is not recoverable is overcome.

Description

(1) Technical field [0001] The invention relates to a single-wall steel hanging box, which belongs to a construction enclosure structure of a deep-water cap platform and a pier column. This invention also relates to the construction method of the single-wall steel hanging box. (2) Background technology [0002] In recent years, with the growth of traffic demand, the increase of bridge span and the increase of foundation water depth, especially in recent years, the continuous construction of the Gulf Strait and cross-river bridges has continuously increased the requirements for deep water foundation construction. From the initial caisson, caisson Well foundations have developed into pipe string foundations, various composite foundations, and then various types of pile foundations, bell foundations, double cap pipe string foundations, multi-column foundations, underground diaphragm wall foundations, etc., to adapt to complex construction conditions . The latest statistics sh...

Problems solved by technology

However, at present, the steel components of the bottom plate of the steel hanging box cannot be recycled, and the amount of pouring concrete for the bottom cover is relatively large, and because it is only bonded by concrete, the controllability of the bonding force between it and the casing as an auxiliary support is poor.

The traditional steel hanging box boom is located inside the hanging box, and the boom needs to be cut off after the back cover, causing unnecessary waste
