Title:
FOUNDATION REINFORCEMENT STRUCTURE AND METHOD FOR HOISTING HEAVY EQUIPMENT CLOSE TO UNCLOSED BUILDING
Document Type and Number:
WIPO Patent Application WO/2021/000444
Kind Code:
A1
Abstract:
Disclosed are a foundation reinforcement structure and method for hoisting heavy equipment close to an unclosed building. Said structure and method solve the problem in the prior art in which the hoisting of a crane may generate lateral earth pressure on an unclosed building, and have the beneficial effect of being able to effectively transfer the hoisting load of a crane, thus preventing the hoisting load of heavy equipment from having a negative impact on a nearby unclosed building. The solution therefor is as follows: a foundation reinforcement structure for hoisting heavy equipment close to an unclosed building, comprising vertically disposed steel sheet piles which are divided into two rows, the two rows of steel sheet piles being provided on left and right sides of a side wall of an unclosed building in a foundation pit, respectively; a first connecting member, the two rows of steel sheet piles being connected by means of the first connecting member, and the first connecting member being layered and provided with several layers; several steel pipe lattice column structures disposed between the two rows of steel sheet piles, the steel pipe lattice column structures also being vertically disposed for vertical force transmission; and backfill soil, which is filled between the two rows of steel sheet piles and the steel pipe lattice columns layer by layer.
