The equipment shall be approved by the Contracting Officer prior to starting the work, and maintained in good working condition by the Contractor during the progress of the work.1.3.2 Grout Plant*NOTE: When the use of limestone dust grouts is approved, a paddle type mixer may be substit

28、uted for the high speed colloidal mixer.*Provide a grout plant consisting of a positive displacement grout injection pump capable of applying up to 1.72 MPa 250 psi pressure, a high speed colloidal mixing machine, and a grout return system. Produce the colloidal grout by mixing in a colloidal mill c

29、onnected to the cone-shaped bottom of a cylindrical drum. Operate the colloidal mill between 800 and 2,000 RPM, creating a high shearing action and subsequent pressure release to make a homogeneous mixture. Provide an injection system capable of continuously pumping grout at rates as low as 5.68 lit
