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, steel flower pipe grouting,San JuanGrouting pipe,San JuanSeamless pipe, pile foundation grouting pipe, grouting pipe manufacturer old brand, price advantage and quality! Each time it is used up, the pipe core and the outer wall of the pipe shall be washed clean.

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, 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.Compared with sleeve valve pipe grouting method, the common disadvantages of grouting pipe grouting method, flower pipe grouting method and drill pipe grouting method are that it is easy to emit slurry along the pipe wall and the grouting layering effect is poor. These disadvantages are particularly prominent when using slurry with good fluidity and long initial setting time; The utility model has the advantages of simple equipment and process, good flexibility, fast construction speed, and is more suitable for situations requiring rapid response.San JuanGrouting pipeAnalysis of basic types and causes of excitation deformation,2023-12-0405:27:00The secondary grouting pipe can only be grouted once and cannot be reused.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.After the grouting hole is drilled,San JuanPrecision tube, install and lower the grouting pipe, mixer and other facilities in the hole.San Juan,Hubli,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, strengthen and correct the deflection of buildings.
