● 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, 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 equipment, grouting pump and the lowered grouting pipe are connected for grouting, and the grouting is carried out according to the requirements. The grouting pump will inject the slurry into the soil. After completing the construction of one grouting section, move the grouting pipe up or down according to the requirements to carry out the construction of the next grouting section.NebaPrecision tubeDomestic prices rebounded and the market showed no sign of stopping,2022-11-2000:58:52The 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.● 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)

The secondary grouting pipe can only be grouted once and cannot be reused.According to the sequence of sectional construction along the stratum depth, 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,NebaGrouting pipe,NebaPrecision tube, 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, 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.Neba,NebaSteel pipe,Pretoria,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.
