GZB-40C high-pressure injection pump Introduction: providing high-voltage power for the high pressure rotary jet mud, for the new building, highway, railway, underground railway soft foundation strengthening reinforcement, renovation of old buildings uneven settlement of high pressure pump manufacturers, dam construction works and under high pressure pump sales Anti dark curtain manufacturers, stalls earth cofferdam, mine plugging, well bucket armband, slope anchor, etc., can also be used in high-pressure water intake flow assisted rock fall coal, downhole hydraulic prop for the fluid, water conservancy and expanded metal anchor bolt pumping high pressure water pressure pump manufacturers, large underground pipeline dredge dredging cleaning, high pressure water jet perforation or other needs with high-pressure liquid as the driving force was the field. Long spiral bored disadvantage when transporting concrete pump concrete, because of its control of pressure uneven, uneven soil pressure, the pile process, when the pressure is greater than the soil pressure concrete pile was slightly enlarged diameter state, on the contrary may form a miniature diameter state. Also outside of the pile and the soil has interwoven phenomenon, so the model is not a uniform cross section of the column, which brought some trouble to pile testing. When dynamic testing the integrity of the column since, due to the pile does not fully comply with uniform cross section; and of course the traditional method can measure static load bearing capacity high pressure injection pump manufacturers, but because of static load for a long time, it is expensive, it is not general use assumed body, the small strain instrument sometimes not a good reaction it is complete, and dynamic testing bearing capacity is also not well used in this pile. So in the dynamic testing, sometimes misjudge phenomenon. Therefore, in the long spiral bored pile construction, pay attention to the speed of delivery of concrete and auger rod to enhance the speed, making it more economical construction, testing more convenient.
