● specification: inner diameter of secondary grouting pipe: mm; Outer diameter: mm; Inner diameter tolerance: & plusmn; .mm； Length of each roll: m.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 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, new and old customers are welcome to consult to determine the grouting pressure and flow, and determine the grouting slurry and its initial concentration.A -m long orifice pipe is installed at the opening of the grouting hole to prevent possible hole collapse. At the same time,FratGrouting pipe, it plays a guiding role in drilling. During grouting, it is used to install orifice closure device to prevent slurry leakage.FratSteel pipeprice,2023-03-2100:43:32The 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,FratSeamless pipe, service, on-site settlement and honest management! The purpose of grouting is to prevent seepage, stop leakage,FratPrecision tube, 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.Frat,Benito-Juarez,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, price advantage and quality! Each time it is used up, the pipe core and the outer wall of the pipe shall be washed clean.
