Title:
CAST-IN-SITU CONCRETE FOUNDATION FOR SOFT SOIL, AND CONSTRUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/093922
Kind Code:
A1
Abstract:
The present invention relates to engineering construction foundations, and specifically relates to a cast-in-situ concrete foundation for soft soil, comprising a plurality of vertically arranged H-shaped steel piles, a plurality of steel bars and a concrete foundation layer. A concrete block is provided above each of the H-shaped steel piles, and the length of the H-shaped steel pile exposed from an upper surface of the concrete block is 800-1500 mm; the steel bars are laid on the concrete blocks, each of the H-shaped steel piles is correspondingly tied to the steel bars, and the concrete foundation layer is poured upward on the basis of the steel bars. The present invention also relates to a construction method for a soft soil cast-in-situ concrete foundation, and solves the technical problem of insufficient bearing capacity of marsh and soft soil foundations. The method differs from a method for a conventional concrete pile foundation comprising cast-in-situ bored piles, precast piles, and the like, requiring large-scale construction equipment. The Amazon rainforest area is mountainous and swampy, with strict environmental requirements, and cannot meet the requirements of large-scale equipment coming in and out. The method of the present invention does not require large-scale equipment, and the pile foundation construction method and tests are simple.
