Embodiment Construction

[0020] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0021] Such as figure 2 As shown, the high-rise anti-seismic building structure based on deep-hole inverted T-piles described in the present invention is based on the deep-hole inverted The T-shaped pile 10 is constructed. Because the inverted T-shaped pile 10 mainly relies on the bottom surface with a larger diameter to carry the load, the bearing capacity is greatly improved. It is also a 30-storey high-rise structure with a total height of 88m and a width of 13.3m. With 70 inverted T-shaped piles 10 with a diameter of 0.8m in the middle and a diameter of 1.6m in the bottom, the whole slab foundation 2 poured on the top surface only needs to be 0.4m thick, and then the basement 3 and the first floor are built on the whole slab foundation 2 in sequence 4 with upper floors 5. During actual operation, the present invention first adopts t...

Abstract

The invention discloses a deep-hole inverted-T-shaped pile based high-rise earthquake-resistant building structure, which is characterized in that a whole-plate foundation is supported by a lower cast-in-place pile, underground and aboveground buildings are sequentially constructed on the whole-plate foundation, the cast-in-place pile is a deep-hole inverted-T-shaped pile, and a pile-base shock-insulating pad is arranged between a pile leg and a foundation. According to the invention, the construction is performed based on the deep-hole inverted-T-shaped pile, so that the bearing capacity of a single bearing pile is effectively improved, and the number of the pile and the construction cost can be significantly reduced. According to the invention, the bottom of the inverted-T-shaped pile is provided with the pile-base shock-insulating pad, and a basic shock-insulating pad is arranged below the whole-plate foundation, so that the vibration of earthquakes is absorbed by using a soft cushion pad below a rigid structure, therefore, an earthquake-resistant effect can be effectively achieved, the earthquake-resistant capacity of a building can be improved, and the life safety of residents in disasters can be ensured.

Description

technical field [0001] The invention relates to the field of building structures, in particular to a high-rise anti-seismic building structure based on deep-hole inverted T-shaped piles. Background technique [0002] Earthquake resistance is an important indicator of building structures. The existing building structures are basically constructed according to the "National Building Standard Design Atlas --- 10SG813 --- Reinforced Concrete Cast-in-place Pile". By means of soil or manpower excavation, pile holes are formed in the foundation soil, and steel cages are placed in them, and the piles are formed after the concrete is poured and solidified. Such as figure 1 As shown, for example, to build a high-rise structure with 30 floors, a total height of 88m, and a width of 13.3m, 150 cast-in-situ piles 1 with a diameter of 0.8m are required, and a 1.5-meter-thick whole-slab foundation 2 is poured on the top surface, and then the whole-slab foundation Build basement 3, first f...
