Special slings shall be used for the lifting of horizontal members such as laminated plates, and the stress at each lifting point shall be uniform to avoid fracture due to uneven stress of members. Grouting method is to put some solidified slurry into the cracks or pores of rock foundation in order to improve its physical and mechanical properties. Professional grouting pipe, steel flower pipe advance small pipe, high-pressure grouting pipe, pipe shed pipe, high price, service, on-site settlement and honest management! The purpose of grouting is to prevent seepage, stop leakage, strengthen and correct the deflection of buildings.● specification: inner diameter of secondary grouting pipe: mm; Outer diameter: mm; Inner diameter tolerance: & plusmn; .mm； Length of each roll: m.

Compared with sleeve valve pipe grouting method, the common disadvantages of grouting pipe grouting method, flower pipe grouting method and drill pipe grouting method are that it is easy to emit slurry along the pipe wall and the grouting layering effect is poor. These disadvantages are particularly prominent when using slurry with good fluidity and long initial setting time; The utility model has the advantages of simple equipment and process, good flexibility, fast construction speed, and is more suitable for situations requiring rapid response.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.ScutaiGrouting pipeThere is a long way to go for stability and development,ScutaiPrecision tube,ScutaiGrouting pipe,2023-12-3103:27:05Process 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.The grouting mechanism includes filling grouting,ScutaiSeamless pipe, infiltration grouting, compaction grouting and splitting grouting. Grouting materials include granular slurry and chemical slurry. Granular slurry is mainly cement slurry, alkali solution method, high chemical grouting method and cement grouting method.

The secondary grouting pipe can only be grouted once and cannot be reused.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.Scutai,Gambela,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.
