Abstract

The invention relates to a novel pile foundation and a construction method thereof, and relates to the technical field of pile foundation construction. The problem that a pile foundation is prone to being inclined and deviated under the loose geological condition is solved. The novel pile foundation comprises a base cylinder, a first reinforcement cage is arranged in the base cylinder, a plurality of reinforcing steel bars which are divergently bent in the circumferential direction of the first reinforcement cage are fixedly connected to the bottom end of the first reinforcement cage, and a plurality of penetrating-out grooves for the reinforcing steel bars to penetrate out are formed in the base cylinder. A plurality of sections of mutually connected second reinforcement cages are fixedly connected to the upper part of the first reinforcement cage, concrete pile columns are integrally poured on the first reinforcement cage and the second reinforcement cages, and a plurality of steel pipe piles connected with the second reinforcement cages are arranged on the peripheral sides of the concrete pile columns. The top and the bottom of the pile foundation are both reinforced, so that the pile foundation is not prone to being inclined and deviated, and the stability of the pile foundation is improved.

Description

technical field [0001] The application relates to the technical field of pile foundation construction, in particular to a novel pile foundation and a construction method thereof. Background technique [0002] The pile foundation is a deep foundation composed of piles and pile caps connected to the pile tops or a single pile foundation connected by columns and pile foundations, referred to as pile foundations. If the pile body is completely buried in the soil and the bottom of the cap is in contact with the soil, it is called a low cap pile foundation; if the upper part of the pile body is exposed to the ground and the bottom of the cap is above the ground, it is called a high cap pile foundation. Building pile foundations are usually low cap pile foundations, and pile foundations are widely used in high-rise buildings. [0003] In the construction process of cast-in-situ piles, usually after drilling, the reinforcement cage is placed in the borehole, and then the concrete a...
