High-speed rail project of H - 60 prestressed pipe pressure slurry

H - Prestressed pipe pressure slurry H - 60 H - 60 prestressed pipe pressure slurry manufacturer H - 4 for the channel bed after slurry 60 prestressed pipe pressure slurry equipment performance should agree with the following rule 1. Mixer speed should be not less than 1000 r/min, the shape of the mixing blade should match the speed, the linear velocity of the blade should not be less than 10 m/s, maximum linear velocity should be constrained within the 20 m/s, can and should be satisfied at the request of the mixing uniform rules of time. 2 used for temporary storage of grout material storage tank should also be with mixing function, and should set the filter on the grid ruler す is not more than 3 m. 1 mpa, the biggest range should be the actual working pressure within its range 25% ~ 75%. Shall not use air pressure type grouting hole grouting pump. Negative pressure of 10 mpa. 5 H - before the hole grouting 60 prestressed pipe pressure slurry preparation should agree with the following rules: 1 should be in field laboratory for trial with grouting material and water, and a variety of materials weighing ( To the quality plan) Should be accurate to + / - 1%. 3 the requirements of the rear can be used in formal grouting. 2 the hole cleaning. Channel of core-pulling molding shall be washed clean and the hole wall completely wet; Metal and plastic pipes, when necessary, should also be washed to remove attached to the hole wall of harmful information. May exist within the channel of oil and so on, can use known non-corrosive effect of prestressed reinforcement and the pipe neutral washing the seam an agent or soap, diluted with water to flush; After washing, should use oil-free compressed air to blow out all the water in the channel. After 3 to grouting equipment cleaning, cleaning equipment should not have residue and water.
