● specification: inner diameter of secondary grouting pipe: mm; Outer diameter: mm; Inner diameter tolerance: & plusmn; .mm； Length of each roll: m.
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.
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， grouting pipe factory， 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.
The secondary grouting pipe can only be grouted once and cannot be reused.
The slurry stop plug used in the slurry stop plug grouting method is the key device to seal the grouting borehole and realize segmented grouting. A good slurry stop plug shall ensure normal operation under the grouting pressure of more than MPa. According to its structure and action principle， the currently used slurry stopper can be divided into mechanical type and hydraulic type. Among them， the mechanical slurry stopper is relatively simple and reliable and is widely used. - is several commonly used slurry stopper structures.
After the grouting hole is drilled， install and lower the grouting pipe， grout stop plug， mixer and other facilities in the hole.

Long term grouting steel flower pipe， steel flower pipe grouting， pile foundation grouting pipe， grouting pipe manufacturer，Changyuan CountySteel pipe， old brand， price advantage and quality! Each time it is used up， steel flower pipe grouting， 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， 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，Changyuan CountyGrouting pipe， and is more suitable for situations requiring rapid response.
