Significantly increase the side frictional resistance of piles
The large-diameter bored pile with mud sheath around the pile circumference and the artificial excavation pile wall, as well as the gap between the wall and the surrounding soil, reduce the side friction resistance of the pile. Under pressure, grout is injected from the pile tip upwards along the pile side, through permeation, splitting, filling, compaction, and cementation, replacing the mud sheath around the pile and filling the gaps, forming a vein-like solid mass around the pile circumference. This is akin to tree roots being implanted in the soil, significantly increasing the side friction resistance of the pile.

Crack Prevention Measures: During the design of concrete mix proportions, it is essential to ensure the concrete has good workability while striving to minimize the unit water content of the concrete.

Basic Principles and Key Points of Common Concrete Crack Treatment: Resin Infiltration Method - Epoxy resin is a common material used for crack infiltration.
Surface Treatment Methods: Includes surface coating and surface patching. Coating is suitable for fine and shallow cracks where slurry is difficult to infiltrate, hairline cracks that do not reach the surface of the reinforcing steel, non-leaking joints, non-expanding cracks, and inactive cracks. Surface patching (geotextile membrane or other waterproof sheets) is applicable for preventing and stopping seepage in large areas with water leakage (such as honeycomb surfaces or difficult-to-locate specific leakage points, expansion joints).
