Problems solved by technology

[0004] When using the enclosure structure in the prior art, since the surroundings of the foundation pit are surrounded by bored piles, but due to the uneven technical level of the workers during actual construction, it is easy to separate the bored piles There is a gap, which will easily lead to water seepage between adjacent bored piles, which will affect the construction and needs to be improved

Embodiment 1

[0063] refer to figure 1 , a deep foundation pit of a super high-rise building, which includes a pit body 1 arranged on the soil body, a plurality of support piles 3 are arranged on the outer edge of the pit body 1 and along its circumference, and the adjacent support piles 3 are interlocked with each other to reduce mutual The gap between the adjacent support piles, the side of the support pile 3 away from the pit body 1 is surrounded by several continuous walls 2, and several continuous walls 2 are integrally formed. The support assembly 4 and the column assembly 5 used to support the support assembly 4; during construction, first pour the continuous wall 2, then drive the support pile 3 into the soil, excavate the pit body 1, and then construct the column assembly 5 and the support assembly 4, the support assembly 4 is supported by the column assembly 5, and the support assembly 4 supports the support pile 3, thereby reducing the possibility of foundation pit collapse; thro...

Embodiment 2

[0080] A construction method for a deep foundation pit of a super high-rise building, the specific steps are as follows:

[0081]S1. Level the site, set out the guide wall 20, excavate the ditch 202, put the installation plate 24 on the positioning rod 29, then contact the steel plate 26 with the guide wall 20, hit the installation plate 24, and insert the positioning rod 29 into the soil At the same time, the steel mesh 22 is sunk, and the cutting edge 28 cuts off the excess soil on the side wall of the ditch 202, which can replace the manual trimming of the ditch 202 by workers, reduce the work burden of the workers, and improve work efficiency; until the steel mesh 22 covers the ditch 202 On the side wall, and pour concrete to form the guide wall 20;

[0082] S2. Excavate the first section of trench 203, bind the reinforcement cage 23, weld the installation cylinder 214 on the connection cylinder 204, adhere the waterproof coiled material 215 to the installation cylinder 21...

Abstract

The invention discloses a super high-rise building deep foundation pit and a construction method thereof, relates to a foundation pit and aims to solve the technical problem in the prior art that water is prone to permeating into the foundation pit. The super high-rise building deep foundation pit and the construction method thereof are characterized in that the super high-rise building deep foundation pit comprises a pit body arranged in a soil body and a plurality of continuous walls arranged at the outer edge of the pit body in a surrounding manner, a plurality of supporting protecting piles arranged on the sides, close to the pit body, of the continuous walls and supporting components for supporting the supporting protecting piles, wherein the pit body is internally provided with vertical column components for fixing the supporting components, and the multiple supporting protecting piles are arranged in the circumferential directions of the continuous walls; when construction is performed, the continuous walls are cast and the supporting protecting piles are hit in, then the pit body is excavated, then the vertical column components and the supporting components are fabricated,so that the supporting protecting piles are supported, and the possibility of foundation pit collapse can be reduced; and by means of two-layer protection of the continuous walls and the supporting protecting piles, groundwater permeating into the foundation pit from positions between the continuous walls and the positions between the supporting protecting piles can be reduced, and reduction of construction influence of the permeating water on the foundation pit is facilitated.

Description

technical field [0001] The invention relates to a foundation pit, more specifically, it relates to a super high-rise building deep foundation pit and a construction method thereof. Background technique [0002] With the development of society, the economy grows rapidly, and the urban population gathers in large numbers, but the land area of ​​the city cannot be increased. This 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 and a height of 100 meters. buildings over 100 meters. 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. [0003] Authorized announcement number is that ...
