DJM machine restructuring of high pressure jet grouting construction stakeout and cloth hole construction in cement mixing pile wall axis as the basis, the translation direction to the lake side 30cm, Wall as a high jet axis injection pump model image parameters, axis by 1.3m on the pitch, measuring holes, and well marked with stakes, compiled on hole number, serial number. DJM machine restructuring of high pressure jet grouting slurry formulation: water-cement ratio of water to determine the appropriate height and increase the amount of ash under the supervision of Engineer (1.2: 1 each addition of water-cement ratio 360kg, cement 300kg), and and marked on the mixer. The configuration process in strict accordance with the marked increase of gray water height and volume control, followed by sufficient mixing Jet supporting injection pump manufacturers, with a hydrometer to measure the density of the prepared slurry pulp density control, do a test every pot, records by hand, add water, ash and slurry density data high injection pump manufacturers, slurry feed can be carried out to meet the requirements. Note: In between mortar mixer and set up a collection hopper filter, filter slurry. The prepared slurry can not isolated, the parking time: should be treated according to the waste slurry at the time when the temperature is above 10 ℃ over the following three hours or 10 ℃ more than five hours.
