Small mud pump is a type of hydraulic filling machine, using pressure water, impact the soil, after wetting water disintegration flow, the formation of mud. Pipeline pressure to the work area to complete the work area of ​​soil sediment deposition. Filling zone with the dehydration of mud consolidation strength continues to increase, to fill the role of solid foundation. Compared with the general mechanical filling pond solid method, it has its own advantages: it loses four steps of loading, unloading, unloading and pressing, saves labor and reduces the cost. High efficiency; at the same time can make full use of spoil on both sides of the dike ponds, depression and embankment reinforcement; from the impact of rain and darkness. Can work continuously. At the same time it also has its own shortcomings: there is a certain choice of soil quality, filling the soil in the early construction of small dry density, larger water content. Low shear strength. Poor sliding stability due to its advantages in the fill pond solid foundation project with the Equatorial Embankment fully play. Therefore widely used. Achieved a better engineering efficiency. In the construction process has the following characteristics A construction preparation phase in the construction preparation phase mainly as follows: (1) Check the water, requiring adequate water near. (2) to determine the soil material field: According to the filling area of ​​solid foundation area, first select the appropriate soil material field. Requires adequate soil, and soil material with wetting, disintegration speed, water permeability characteristics, the general sandy loam is more appropriate. (3) Erection of high and low voltage lines and installation of impulse filling units. (4) Chongji Filling and Filling Area and Qingmo work area (5) Construction measurement setting out, set the water gauge. To control the filling should pay attention to the construction design slope ratio control. In general, it should be completed in two batches of successful filling pulp, pulp pipeline laying and drainage according to the embankment filled with horse solid foundation soil, water features. Hydraulic blowing should be mastered early, thick, Kennedy, Pai are five characteristics: early start to prevent passive flood season. Slurry thick; cofferdams strong; to enhance drainage; flushing speed uniform quality, to avoid weak links. Pay attention to the structural characteristics of the soil when making pulp. Make full use of the role of pressure water, stirring soil and mud, control mud concentration. In the construction process must be good off. It is directly related to efficacy, cost and quality. When mud is too thin, take timely measures. Do not allow a lot of slurry output, should pay attention to the layout of the pipeline pressure slurry: generally should follow the following principles: (1) smooth lines, avoid dead ends, dead bending. (2) When filling the ponds on both sides of the bank by blow filling, the depression of the mud pipe may be relatively fixed. (3) Blow fill for platform cover weight. Out of the mouth should be a timely extension of the forward or increase the branch to control the slope ratio to reach the design of construction elevation, should not be relatively fixed. In the process of blowing, each time filling thickness should not exceed 1m. And should be sub-paragraph. Sub-warehouse intermittent construction. Layered filling. Analyze water discharge through drains and channels. Drainage can choose overflow weir, water, culverts and other forms of three daily work Small mud pump is a careful management and control, careful operation of construction methods, should pay attention to its regular work. (A): Strengthen the pipeline, cofferdam inspection. Grasping the working status of pipelines and the progress of filling and filling (2) Making overall arrangements for onshore and onshore construction, timely dispatching operation of filling and filling different positions and increasing work efficiency (3): Checking the soil and mud concentration during excavation and filling, Effective utilization rate of earthwork (4): Test the performance of dredger fill, deposition along the sediment, particle size distribution. Dry density and strength and the relationship between filling and consolidation time (E): to control the emission of unstimulated particles in the tail water content. Prevent siltation of drainage system (six): pay attention to safety in production, strengthen organizational discipline. Tightly monitor the variation of distribution boxes, motors, cables and transformer systems, strictly monitor the distribution of pipelines and prevent the phenomenon of plugging and draining. Pay attention to hurt the water cannons, electric shock and other accidents. In the same embankment filled pond solid foundation project, taking into account project funding, soil conditions and other factors fully apply the small mud pump filling construction, improve work efficiency, save investment.
