Technical parameters of grouting reinforcement.

Categorization	Sports event	Parameters
Drilled hole	Diameter of hole	42 mm
	Pitch of hole	The outdoor holes are around 1.2 to 2.0 m from the outer wall and aligned with the shear walls on the axis. Indoor holes are placed along the periphery of the platform pile foundation, with densification in areas with more settlement. The configuration is subject to change dependent on conditions faced on-site
	Depth of hole	Zones 1 and 2 have a drilling depth of 22.9 m, whereas Zone 3 is 26.4 m, extending 1.0 m into the discontinuous weathered granite; these dimensions are subject to modification based on actual field conditions
Grouting	Slurry ratio	Adjust the actual situation on site
	Stresses	Lifting pressure about 0.3 ~ 3.0 MPa (adjusted according to the actual situation of the site)
	Slurry setting speed	About 10 s ~ 90 s
	Slurry spreading radius	The diffusion radius of the slurry is not less than 2.5 m
	Slurry Entry Rate	Slurry feed rate not less than 25%
