slush pump on defeated mud hose, makes in mud hole Mud is input in hydraulic reclamation device by defeated mud hose, in the presence of split flow pump by mud by playpipe through shower nozzle spray to Hydraulic reclamation position, playpipe is rotated while continuous injection according to the requirement of setting, mud is sprayed along the bottom of foundation ditch Penetrate, when underlayer thickness reaches 40~60cm, that is, stop blowing-filling sludge when covering drainpipe, finally with rammer compacter by the bottom of foundation ditch Layer mud compacting；(6) dredge fillAfter the mud compacting of bottom, hydraulic reclamation device is moved to the point midway of margin of foundation pit, then by the shower nozzle of playpipe Foundation ditch is directed at, starts slush pump, mud is entered hydraulic reclamation device by defeated mud hose, then open split flow pump, pass through mud Playpipe carries out hydraulic reclamation through shower nozzle to foundation ditch, when corresponding discharging opening blocking on split flow pump and can not normal work when, pass through by Playpipe is attached with others discharging flange again, realizes continuous dredge fill, playpipe is from left to right successively to rectangle Grid carries out hydraulic reclamation, while controls in shower nozzle the spacing between two pressuring plates up and down, according to the actual size and depth of foundation ditch, The hydraulic reclamation speed of mud is adjusted, the solar components on hydraulic reclamation device give split flow pump to provide electric energy, it is continuously worked, when close When the loading of the rectangle grid of hydraulic reclamation device reaches 50~80cm depth, adjust the position of hydraulic reclamation device or change playpipe Angle position, hydraulic reclamation is carried out to other rectangle grids, until the mud depth in whole foundation ditch reaches 50~80cm, it is most laggard The dredge fill of row top layer, until whole foundation ditch hydraulic reclamation finishes；(7) construction detectionAfter dredge fill terminates, the position of foundation ditch hydraulic reclamation is corrected by level meter and measurement equipment, makes foundation ditch overall Construction reach the standard of setting, the position for occurring being recessed to hydraulic reclamation position carries out repairing hydraulic reclamation, finally covered above foundation ditch One layer of geotextiles of lid；(8) final acceptance of constructionAfter dredge fill reaches sets requirement, first defeated mud hose is cleared up, and is recycled in chest, then with clear water to blowing The outside of action is cleaned, and connects water-in flange with water pipe, while opens water-output flange, makes current in split flow pump Portion is rinsed, and is reclaimed after drying.
