According to the sequence of sectional construction along the stratum depth,Dunajska Streda Seamless pipe, grouting can be divided into sectional downward, sectional upward and sub full depth grouting. The segmented downward type is to start from the ground, drill section holes from top to bottom and inject section slurry. After each injection section, continue to extend the drilling and grouting, 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,Dunajska Streda Steel pipe, 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.Push the rock powder and sundries that are not washed, remain at the hole bottom, or stick to the hole wall out of the grouting range so as to improve the bonding strength and impermeability between the slurry stone body and the fracture surface.Dunajska Streda Precision tubeQuality risk,2023-03-2200:27:06Process 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 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.

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.Dunajska Streda ,Shenyang,Special slings shall be used for the lifting of horizontal members such as laminated plates, and the stress at each lifting point shall be uniform to avoid fracture due to uneven stress of members. Grouting method is to put some solidified slurry into the cracks or pores of rock foundation in order to improve its physical and mechanical properties. Professional grouting pipe, steel flower pipe, advance small pipe, high-pressure grouting pipe, grouting pipe factory, high price, service, on-site settlement and honest management! The purpose of grouting is to prevent seepage, stop leakage
