Technical Field

[0001] The present invention relates to the technical field of pile foundation reinforcement, and in particular to a pile foundation reinforcement structure and a crack repair feedback device based on microbial mineralization reaction. Background Art

[0002] A pile foundation, also known as a deep foundation (see figure) consisting of a pile and a pile cap connected to the top of the pile (referred to as the pile cap), or a single pile foundation consisting of a column connected to the pile base, is called a low-cap pile foundation. If the pile is completely buried in the soil and the bottom of the pile cap is in contact with the soil, it is called a low-cap pile foundation. If the upper part of the pile is exposed above ground and the bottom of the pile cap is above ground, it is called a high-cap pile foundation. Building pile foundations are typically low-cap pile foundations. Pile foundations are widely used in high-rise buildings.

[0003] Pile foundation reinforcement is a method of improving the bearing capacity and stability of soil foundations through engineering techniques. It is primarily used to address problems such as foundation settlement, uneven settlement, and excessive structural loads, thereby improving the safety and durability of buildings or infrastructure. Traditional reinforcement methods include concrete reinforcement and soil nailing, but these methods are costly and time-consuming. Microbial mineralization technology has attracted widespread attention due to its advantages of being pollution-free, low-cost, and easy to use.
