[Tianjin-strong high-pressure pump Co., Ltd. to recommend the star product】 Triple Tube Rotary Jetting applicable engineering Triple Tube Rotary Spray can be used for a permanent foundation reinforcement engineering, construction engineering before use, high-rise building foundation reinforcement, improve the bearing capacity; It can also be used after the project is completed, and the inclination to stop settlement building. Can also be used for temporary works such as excavation pit prevent uplift, quicksand, impervious waterproof curtain jet grouting rig, increasing the stability of the slope, to prevent soil sliding. Press engineering purposes can be divided into the following five projects: [Tianjin-strong high-pressure pump Co., Ltd. to recommend the star product] triple tube construction principle and process of high pressure spraying pile of three-tube method Churning is a water, gas injection, perfusion slurry injection mixing method. That is, with three high-pressure water jet pipe and air simultaneously transjector, and cut soil body Jet rig sale price, by the rise of the air force was ruled out by a broken soil surface; the same time, another nozzle grout Low pressure spray injected into the cut, stirred the foundation, make the grout reinforcement and soil mixing to achieve the purpose of high pressure jet grouting rig, the reinforcement diameter of up to 800 ~ 2000mm. Churning three-tube method, should be sent to the high-pressure water, sending mud and water, compressed air; the first injection should reach a predetermined pressure injection amount after spraying, and then gradually increase the grouting pipe, grouting tube segments to enhance ride then the length of not less than 100mm; when it reaches design pile height or ground underflow slurry phenomenon, should immediately stop the work of the current Jet pile and pulled out a spin nozzle and clean lines. Triple tube method is the slurry with compressed air spray while spraying hydraulic rotary drilling rig, in addition to extend the spray distance, increase cutting ability, but also to promote the exclusion of Wasteland, plus solid weight per unit volume.
