● specification: inner diameter of secondary grouting pipe: mm; Outer diameter: mm; Inner diameter tolerance: & plusmn; .mm； Length of each roll: m.The secondary grouting pipe can only be grouted once and cannot be reused.

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.After the grouting hole is drilled, install and lower the grouting pipe, grout stop plug, mixer and other facilities in the hole.Port amuellisGrouting pipemanufacturer,2023-11-3002:25:56● specification: inner diameter of secondary grouting pipe: mm; Outer diameter: mm; Inner diameter tolerance: & plusmn; .mm； Length of each roll: m.Repetitive grouting pipe can be reused for many times. Long term grouting steel flower pipe,Port amuellisSeamless pipe, steel flower pipe grouting, pile foundation grouting pipe, grouting pipe manufacturer, old brand, 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, aerated silicification method and electric double liquid silicification method.Compared with sleeve valve pipe grouting 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,Kampung Baru Subang and is more suitable for situations requiring rapid response.Port amuellis,Port amuellisGrouting pipe,● features: the grouting pipe is divided into secondary grouting pipe (ccll-y grouting pipe, qdm-it grouting pipe, ccll-y full section grouting pipe) and repetitive grouting pipe (ccll-d grouting pipe, ccll-d full section grouting pipe)
