grouting can be divided into sectional downward

The secondary grouting pipe can only be grouted once and cannot be reused.● specification: inner diameter of secondary grouting pipe: mm; Outer diameter: mm; Inner diameter tolerance: & plusmn; .mm； Length of each roll: m.

According to the sequence of sectional construction along the stratum depth, sectional upward and sub full depth grouting. The segmented downward type is to start from the ground, continue to extend the drilling and grouting, so as to alternately carry out until the designed final grouting depth,KuliakanSeamless pipe, and then carry out re grouting from bottom to top; The sectional upward pattern is that the grouting hole is drilled to the final grouting depth at one time. All kinds of grouting pipes, steel flower pipes, advance small conduits, high-pressure grouting pipes, pipe shed pipes and the formal qualification of grouting pipe factory are welcome to inquire by telephone and sincerely invite cooperation! Grout stop shall be used for bottom-up sectional grouting; The secondary full depth grouting method is to drill the grouting hole to the final grouting depth, and then conduct secondary grouting for the full depth.Push the rock powder and sundries that are not washed, remain at the hole bottom, or stick to the hole wall out of the grouting range, so as to improve the bonding strength and impermeability between the slurry stone body and the fracture surface.KuliakanSeamless pipePrecautions for double ruler straightening2023-08-0105:36:23The secondary grouting pipe can only be grouted once and cannot be reused.The secondary grouting pipe can only be grouted once and cannot be reused.

Process flow: drill in place → Drilling → Mud injection → Run casing → Continue drilling → Slag removal → Hole cleaning → Hoist the reinforcement cage → Water jetting and bottom cleaning → Concrete conduit → Placing concrete → Catheter & rarr; The pile top reinforcement can be divided into single liquid silicification method, double liquid silicification method, aerated silicification method and electric double liquid silicification method.A -m long orifice pipe is installed at the opening of the grouting hole to prevent possible hole collapse. At the same time, it plays a guiding role in drilling. During grouting, it is used to install orifice closure device to prevent slurry leakage.Kuliakan,Repetitive grouting pipe can be reused for many times. Long term grouting steel flower pipe, steel flower pipe grouting,KuliakanPrecision tube, pile foundation grouting pipe, grouting pipe manufacturer,KuliakanSteel pipe, old brand, price advantage and quality! Each time it is used up, the pipe core and the outer wall of the pipe shall be washed clean.
