Super high-rise building deep foundation pit and construction method thereof

Abstract

The invention relates to a super high-rise building deep foundation pit which comprises a foundation pit body. The foundation pit body comprises a pit main body excavated in the ground, first fender posts vertically penetrating into the pit main body along the ground and located at the peripheral side of the pit main body, two circles of second fender posts vertically penetrating into the ground along the peripheral side end of the pit main body, water stop piles vertically penetrating into the ground from the position between the two circles of second fender posts and a steel trestle built at the upper ends of the second fender posts and the water stop piles, and mounting bases for fixing the lower end of the steel trestle are arranged at the upper ends of the water stop piles and the second fender posts. The super high-rise building deep foundation pit and the construction method have the characteristics of convenience in foundation pit construction, convenience in steel trestle building and the like.

Description

technical field

[0001] The application relates to the technical field of infrastructure construction, in particular to a deep foundation pit of a super high-rise building and a construction method thereof. Background technique

[0002] At present, with the development of society, rapid economic growth, and a large number of urban populations, but the urban land area cannot be increased, which requires building buildings to be built higher and higher, resulting in super high-rise buildings. Super high-rise buildings refer to more than 40 floors. Buildings over 100 meters in height. At present, the traditional deep foundation pit construction method is open construction. The method is to excavate vertically or with a large slope after enclosing the supporting structure. The basement structure is constructed layer by layer, and the above-ground structure construction is carried out after the underground structure is completed.

Examples

Embodiment Construction

[0039] The following is attached Figure 1-6 The application is described in further detail.

[0040] see figure 1 , a deep foundation pit for a super high-rise building, comprising a foundation pit body, the foundation pit body comprising a pit body 1 excavated on the ground, a first surrounding protection pile 2, a second surrounding protection pile 3, a water stop pile 4 and built on the ground The steel trestle 5 in the pit body 1.

[0041] The pit body 1 is a square deep pit, the side length of the pit body 1 is 40 meters, and the depth is 10 meters. The first enclosure pile 2 is a cylindrical concrete pouring pile. The diameter of the first enclosure pile 2 is 30 cm, the length 20 meters, a pouring hole with a depth of 20 meters is drilled vertically outside the pit body 1, and the steel cage is sunk into the pouring hole and then poured to form the first enclosure pile 2, and each first enclosure pile 2 to the outside of the pit body 1 and the distance between adjace...
