DJM machine restructuring of high pressure jet grouting Drilling: drilling in two sequences. Improved use 130mm swing over the alloy drill drilling, in order to prevent the collapse of the use of Slurry Wall. The final hole to be sprayed for a long time, should be stamped at the orifice be protected from debris falling into the hole. After the rig in place mat smooth firm, horizontal ruler to measure the level of the body, vertical vertical, drilling holes and Design hole deviation of not more than 50mm. Tilt rate should not exceed 1%, rig caliber 127mm. Drilling depth is not less than the design bottom elevation requirements. Drilling 3m each application level tape measure once during the drilling process, avoid tilting deviation caused by the drilling process. Tianjin-strong high-pressure pump Co., the company developed a high quality and efficiency of the single-pipe injection pump manufacturers price, double and triple tube high voltage rotating drill pipe, drill the series have passed the test of the harsh environment of the production site injection pump manufacturers , a successful construction effect. The company Jet rigs and accessories, complete sets of high spray equipment, high-pressure injection pump and accessories manufacturer of high injection pump, high pressure jetting trolley, double-barreled drill, drill three sets of products, specializing in high-pressure pipe ram Services . Dual fluid injection pump dual fluid injection pump is a single-cylinder double-acting triplex piston pump, can transport slurry, yellow mud, water glass, oil, water and other media. Two media simultaneously conveying a medium can also be transported separately, stable performance, compact structure, easy operation and maintenance. Dual fluid injection pump is widely used in tunnels, mines mining face grouting plugging; rock roadway and concrete wall grouting plugging water; tunnel cracks, broken rock, rock reinforcement evacuation; anchor grouting; backfill grouting and to prevent surface subsidence, prevent landslides, correct skewed buildings grouting carried out and so on.
