The secondary grouting pipe can only be grouted once and cannot be reused.Repetitive grouting pipe can be reused for many times. Long term grouting steel flower pipe,North Santa CruzPrecision tube, steel flower pipe grouting, pile foundation grouting pipe, grouting pipe manufacturer, old brand price advantage and quality! Each time it is used up, the pipe core and the outer wall of the pipe shall be washed clean.

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.A -m long orifice pipe is installed at the opening of the grouting hole to prevent possible hole collapse. At the same time, it plays a guiding role in drilling. During grouting, it is used to install orifice closure device to prevent slurry leakage.North Santa CruzPrecision tubeWhat should we pay attention to when using flame correction,2024-04-2814:33:55Process 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 secondary grouting pipe can only be grouted once and cannot be reused.

● 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)Compared with sleeve valve pipe grouting method, the common disadvantages of grouting pipe grouting method, good flexibility,North Santa CruzSeamless pipe, fast construction speed, and is more suitable for situations requiring rapid response.North Santa Cruz,North Santa CruzSteel pipe,SaintLaurent, qdm-it grouting pipe, ccll-y full section grouting pipe) and repetitive grouting pipe (ccll-d grouting pipe, ccll-d full section grouting pipe)
