[Tianjin-strong high-pressure pump Co., Ltd. to recommend the star product] single pipe high pressure rotary jet pile construction program and background materials (cement) arrangement (1) Background (preparation of the corresponding machine number) and cement piled station should avoid the pile-bit range, It does not affect traffic. (2) background and cement piled station shall be connected together highway soft foundation treatment, and the erection of protective equipment.

[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, the injection flow rate 80 ~ 120L / min Tonghua soft foundation treatment, 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.
