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.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.
After the grouting hole is drilled, install and lower the grouting pipe, grout stop plug, mixer and other facilities in the hole.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.ZakapaPrecision tubeAre you excited by the structure and application characteristics of,2023-01-2301:02:27Special 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,ZakapaGrouting pipe, steel flower pipe, advance small pipe, high-pressure grouting pipe, pipe shed pipe,ZakapaPrecision tube,ZakapaSeamless pipe, grouting pipe factory, high price, on-site settlement and honest management! The purpose of grouting is to prevent seepage, stop leakage, strengthen and correct the deflection of buildings.The secondary grouting pipe can only be grouted once and cannot be reused.
The 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, alkali solution method, high chemical grouting method and cement grouting method.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.Zakapa,Bejaia
