● specification: inner diameter of secondary grouting pipe: mm; Outer diameter: mm; Inner diameter tolerance: & plusmn; .mm； Length of each roll: m.Repetitive grouting pipe can be reused for many times. Long term grouting steel flower pipe, steel flower pipe grouting, pile foundation grouting pipe, grouting pipe manufacturer, 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.

According to the measured water absorption of the borehole, verify the water permeability of the rock stratum and provide professional quality assurance for grouting pipe, steel flower pipe, advance small conduit, high-pressure grouting pipe, pipe shed pipe and grouting pipe factory. During the preferential activities, new and old customers are welcome to consult to determine the grouting pressure and flow, and determine the grouting slurry and its initial concentration.According to the sequence of sectional construction along the stratum depth, grouting can be divided into sectional downward, sectional upward and sub full depth grouting. The segmented downward type is to start from the ground, drill section holes from top to bottom and inject section slurry. After each injection section, so as to alternately carry out until the designed final grouting depth, 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,SteinerGrouting pipe, 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.SteinerSeamless pipeDevelopment Curriculum,2023-05-0800:49:18The grouting mechanism includes filling grouting, infiltration grouting, compaction grouting and splitting grouting. Grouting materials include granular slurry and chemical slurry. Granular slurry is mainly cement slurry, and chemical slurry includes silicate (water glass) and high slurry. Silicification method,SteinerSeamless pipe, alkali solution method, high chemical grouting method and cement grouting method.Repetitive grouting pipe can be reused for many times. Long term grouting steel flower pipe, steel flower pipe grouting, pile foundation grouting pipe, grouting pipe manufacturer, 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.

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.According to the sequence of sectional construction along the stratum depth, grouting can be divided into sectional downward, sectional upward and sub full depth grouting. The segmented downward type is to start from the ground, drill section holes from top to bottom and inject section slurry. After each injection section, continue to extend the drilling and grouting, so as to alternately carry out until the designed final grouting depth, 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, 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,SteinerSteel pipe, and then conduct secondary grouting for the full depth.Steiner,La-Esperanza,Repetitive grouting pipe can be reused for many times. Long term grouting steel flower pipe, steel flower pipe grouting, pile foundation grouting 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.
