● features: the grouting pipe is divided into secondary grouting pipe (ccll-y grouting pipe，RamshaherPrecision tube， ccll-y full section grouting pipe) and repetitive grouting pipe (ccll-d grouting pipe，RamshaherSteel pipe，RamshaherGrouting 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.

According to the sequence of sectional construction along the stratum depth， sectional upward and sub full depth grouting. The segmented downward type is to start from the ground grouting can be divided into sectional downward， drill section holes from top to bottom and inject section slurry. After each injection section， continue to extend the drilling and grouting， so as to alternately carry out until the designed final grouting depth， and then carry out re grouting from bottom to top; The sectional upward pattern is that the grouting hole is drilled to the final grouting depth at one time. All kinds of grouting pipes， steel flower pipes， advance small conduits high-pressure grouting pipes， pipe shed pipes and the formal qualification of grouting pipe factory are welcome to inquire by telephone and sincerely invite cooperation! Grout stop shall be used for bottom-up sectional grouting; The secondary full depth grouting method is to drill the grouting hole to the final grouting depth， and then conduct secondary grouting for the full depth.
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.

The 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.

RamshaherNew KuznetskIt is used to seal the construction joints， cold 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.
