[Tianjin-strong high-pressure pump Co., Ltd. to recommend the star product - high-pressure pump] Features: instantaneous flow pulsates This is because the reciprocating pump, the suction and discharge of the liquid medium is alternately process, and the piston displacement process, its speed and constantly changing. Only one pump working chamber, the instantaneous flow pump not only change over time, and is not continuous. With the increase in the working chamber, the pulsation amplitude of the instantaneous flow of increasingly smaller pile sealing curtain manufacturers, and even can be considered practically steady stream. Soft Ground Treatment Methods: sand cushion method such as mechanical design and construction, in determining the thickness of sand mats, you should consider the weight of the machine, the ground contact pressure of the tire pile sealing curtain, eccentricity and soft soil surface strength . Table 1 shows the standard sand cushion thickness. On the very soft ground, only sand cushion to ensure the passage of large construction machinery often requires thick sand cushion triple tube sealing curtain pile, it is not economical sealing curtain pile driver model, so often associated with Surface drainage or pad materials and Law. Fill a large area and drainage long distance, is expected to have multiple groundwater seepage, if the only mountain sand for sand cushion, can not obtain sufficient drainage effect, should be set up blind ditch, drainage from the sand cushion not within the appropriate short long.
