cold joints

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, high-pressure grouting pipe,StolinSteel pipe, pipe shed pipe, 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.● specification: inner diameter of secondary grouting pipe: mm; Outer diameter: mm; Inner diameter tolerance: & plusmn; .mm； Length of each roll: m.

Push the rock powder and sundries that are not washed, remain at the hole bottom, so as to improve the bonding strength and impermeability between the slurry stone body and the fracture surface.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.StolinPrecision tubeThe price plummeted and the industry lost all its money,2024-03-1103:03:12● 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, cold joints, pipe seepage joints and gaps between ground walls in concrete.

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.The grout stop plug grouting method is generally used for Rock Fissure Grouting. The grouting pipe is provided with a grout stop plug, which can close the upper part of the grouting section. The main construction steps are as follows: the grouting hole is drilled by a rotary drill. All grouting holes in the rock stratum are required to be drilled by coring in order to find out the and distribution of rock stratum fractures. The coring rate shall reach ~ % in the rock stratum and % in the broken rock stratum. The drilling cleaning fluid is mainly clean water. If the rock is broken and the hole collapse is serious, thin mud slurry can also be used as circulating fluid.Stolin,Bangangt é,The secondary grouting pipe can only be grouted once and cannot be reused.
