● specification: inner diameter of secondary grouting pipe: mm; Outer diameter: mm; Inner diameter tolerance: & plusmn; .mm； Length of each roll: m.
It is used to seal the construction joints， pipe seepage joints and gaps between ground walls in concrete. It is very suitable to install grouting pipes between the joints of new and old concrete. When water seeps into the joint， the PVC port slurry on the surface can be set to seal the joint. The appropriate grouting time can be selected at the end of concrete curing. Leakage joints can also be sealed with this. Provide long-term grouting pipe， steel flower pipe， advance small pipe， pipe shed pipe， grouting pipe factory， old brand， price advantage and quality guarantee! In the embedded grouting pipe， the slurry can seal the construction joint， cold joint， pipe leakage and the joint between the ground wall.
The secondary grouting pipe can only be grouted once and cannot be reused.

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， pipe shed pipe and grouting pipe factory. During the preferential activities， new and old customers are welcome to consult to determine the grouting pressure and flow， and determine the grouting slurry and its initial concentration.
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，SabzevalSteel pipe，SabzevalSeamless pipe， the mechanical slurry stopper is relatively simple and reliable and is widely used. - is several commonly used slurry stopper structures.

SabzevalShegord AvilaThe 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.
