● features: the grouting pipe is divided into secondary grouting pipe (ccll-y grouting pipe, qdm-it grouting pipe,IsalkoPrecision tube, ccll-y full section grouting pipe) and repetitive grouting pipe (ccll-d grouting pipe ccll-d full section grouting pipe)● 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, good flexibility, fast construction speed and is more suitable for situations requiring rapid response.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.IsalkoPrecision tubeJin Jiu declared bankruptcy, and the decline remained,2022-12-1700:19:16Process 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, infiltration grouting,IsalkoSteel pipe, 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.

● specification: inner diameter of secondary grouting pipe: mm; Outer diameter: mm; Inner diameter tolerance: & plusmn; .mm； Length of each roll: m.A -m long orifice pipe is installed at the opening of the grouting hole to prevent possible hole collapse. At the same time,IsalkoGrouting pipe, it plays a guiding role in drilling. During grouting, it is used to install orifice closure device to prevent slurry leakage.Isalko,Okahandja,The grouting mechanism includes filling grouting, infiltration grouting, compaction grouting and splitting grouting.
