Embodiment Construction

[0007] The method of the present invention adopting cylindrical prestressed ground hoops to strengthen the foundation structure of high-rise buildings in soft soil has the following advantages: the joint of the cylindrical prestressed ground hoops with the underground foundation and the above-ground buildings and extending to the reinforced floor of the ground hoops is common Therefore, the soil creep and deformation caused by the gravity of the entire high-rise building are mainly limited between the cylindrical prestressed hoop and the high-rise building and the ground. Improve the stability of high-rise buildings and the ability to resist earthquake disasters.

[0008] Embodiments of the present invention will be further described in conjunction with the accompanying drawings.

[0009] As shown in the figure, after excavating the shallow strata, ram and bury a cylindrical prestressed ground hoop 1 made of single-layer or multi-layer corrosion-resistant high-strength materia...

Abstract

The present invention relates to a foundation structure of high-rise building on the soft soil stratum, its technical scheme is as follows: rammer-embedding single layer or several layers of cylindrical prestressed ground hoops made of anticorrosive high-strength material or reinforced concrete around the high-rise building and reinforcing the joined place of underground foundation and on-ground building and ground floor to ground hoops to make the said creep deformation due to gravity force of high-rise building mainly be limited in the rang. Said invention is applicable to all soft soil stratums for building high-rise building.

Description

1. Technical field [0001] The invention relates to a method for strengthening the foundation structure of a high-rise building in a soft soil layer by adopting a cylindrical prestressed ground hoop. 2. Background technology [0002] To build high-rise buildings in soft soil layers, it is often necessary to ram many deep ground piles into hard geological layers to support the pressure caused by the entire building on the surface of the ground. Improper handling of ground piles often causes buildings to sink, lean and even collapse. [0003] The purpose of the invention is to make the high-rise buildings in a more stable state on the ground pile foundation of the high-rise buildings in soft soil. 3. Contents of the invention [0004] The present invention uses cylindrical prestressed hoops to strengthen the foundation structure of high-rise buildings in soft soil layers, which is achieved through such a technical scheme: after excavating the shallow stratum, within the appr...
