verify the water permeability of the rock stratum

The secondary grouting pipe can only be grouted once and cannot be reused.The secondary grouting pipe can only be grouted once and cannot be reused.

According to the measured water absorption of the borehole,La luvilleGrouting pipe, 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 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.La luvilleSeamless pipeIntroduction to manufacturing process and characteristics,2024-03-1618:31:51● 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)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.

During the preferential activities,La luvilleSteel pipe, new and old customers are welcome to consult to determine the grouting pressure and flow,La-Cabima,The grouting mechanism includes filling 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.
