[Tianjin-strong high-pressure pump Co., Ltd. to recommend the star product] Injection is guaranteed range of soil reinforcement can effectively cut before mixing uniformly and make the pile diameter to 700mm, grouting pressure should not be less than 25MPa. Stripping tube speed control 25cm / min, high pressure jet grouting rig type, injection flow rate 80 ~ 120L / min, the rotational speed of 20 ~ 40r / min so that the soil is fully cut stirring. With a pile construction stoppage for any reason, we must do then pile measures general then pile length> 0.5m. [Tianjin-strong high-pressure pump Co., Ltd. to recommend Star Products] Dual tube and triple swirler under high pressure is the use of the first drilling, and put people rotating nozzle, high-pressure jet cutting methods the soil and cement slurry was stirred, Taian high pressure Churning rig, plus solid or foundation reinforcement methods cut-off wall after the formation of mixing were cured. Double tube method is water and cement slurry injection at the same time, rotate, cement slurry spray nozzle, spray nozzle outside. Triple tube method, water, gas and cement slurry three media, grouting pipe consists of three coaxial pipe consisting of different diameters, the inner tube conveying water, piped gas flow in the outer tube transport cement slurry. High-pressure water jet cutting gas no shaft surrounding soil, so that adequate mixing of soil and cement slurry, high pressure jet grouting rig Daqing, while jet, while rotating and lifting grouting pipe, forming a larger diameter plus solid.
