According to the MICP biological curing
pervious concrete pile and the construction method thereof, appropriate microorganisms and cementing liquid are sprayed to the surface of a
pile body,
urease is generated through
metabolism of the microorganisms to catalyze
carbonate salting-out reaction, and a firm
calcium carbonate filling and cementing material is generated on a
pile-soil interface; the
surface roughness of the
pervious concrete pile is increased, so that the pile-soil interface
frictional resistance is improved, more loads are transmitted to a soil body by improving the pile body side
frictional resistance, the soil body can bear the more loads, the bearing effect of a composite foundation is achieved to the maximum extent, and the
bearing capacity of the composite foundation is effectively improved. Biological
slurry is evenly adsorbed on the surface of the side wall of the pile body through the adsorption performance of
activated carbon, the purpose of even curing is achieved, the biological
slurry permeates into the pile body through the
rough surface of the side wall of the
pervious concrete pile and pores, a
calcium carbonate body generated through internal reaction plays a role similar to an anchor rod, and the external
calcium carbonate body is firmly fixed; and finally, a stable side wall
calcium carbonate high-friction-resistance reinforcement body is formed.
