The slurry stop plug used in the slurry stop plug grouting method is the key device to seal the grouting borehole and realize segmented grouting. A good slurry stop plug shall ensure normal operation under the grouting pressure of more than MPa. According to its structure and action principle, the currently used slurry stopper can be divided into mechanical type and hydraulic type. Among them, the mechanical slurry stopper is relatively simple and reliable and is widely used. - is several commonly used slurry stopper structures.The grouting equipment, grouting pump and the lowered grouting pipe are connected for grouting,LavenderSteel pipe, 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.LavenderSteel pipeRepresentation of reduction of area,LavenderPrecision tube,2023-12-2616:44:42● specification: inner diameter of secondary grouting pipe: mm; Outer diameter: mm; Inner diameter tolerance: & plusmn; .mm; Length of each roll: m.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.
● features: the grouting pipe is divided into secondary grouting pipe (ccll-y grouting pipe, qdm-it grouting pipe,LavenderSeamless pipe, ccll-y full section grouting pipe) and repetitive grouting pipe (ccll-d grouting pipe, ccll-d full section grouting pipe)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.Lavender,Istaravshan,The secondary grouting pipe can only be grouted once and cannot be reused.
