Below be example with the high-pressure rotary jet grouting pile, set forth the process processed of mixing of cement mortar.
(1) determines the ratio of mud
Determining of the ratio of mud is general by design and code requirement setting, is 1:1 as the ratio of mud of this engineering high-pressure rotary jet grouting pile, solid density ρ=1820kg/m3.
(2) quantity that at every turn feeds intake is determined
The speed that the output torque of volume, first mixer 14 of agitator 13 of mainly containing the quantity that at every turn feeds intake stirs and effect etc. are many-sided considers that this engineering then adopts following method to determine:
1. agitator 13 is 1.7m with the diameter, and high height is the circular cone of 1m for the cylinder of 1m and diameter are 1.7m, and volume is about 3.026m
3For example describes, the ratio of mud is that the cement slurry density of 1:1 is ρ=1820kg/m
3, then maximum cement mortar quality is:
M=ρV=1820×3.026=5508.05kg
Then the quality of cement and water is m=M/2=2754.025kg
Namely the quality that at every turn can drop into cement and water by agitator 13 maximum volumes is 2754.025kg.
2. the peak power output P=7KW with first mixer 14 is that example describes, consider the size of output torque, add the viscous force of cement mortar, simultaneously in order to guarantee mixing effect and efficient, each cement that drops into and the quality of water all are m=1600kg, and the cement mortar that namely at every turn can mix system is 1758L.
(3) parameter is set
According to top definite quantity that feeds intake at every turn, parameter is set in automatic metering system.
1. the cement setting of parameter that feeds intake
Maximum range with LOAD CELLS 16 is that 500kg is that example describes, cement quality according to top definite each stirring is m=1600kg, be 400kg so set the weight of each discharging at DH-960 Ш type controller, divide and drop into for 4 times, the cumulative investment quality is 1600kg, namely finished the feed intake setting of parameter of cement.
2. the setting of water input parameter
Before digital display time relay 7 is set the water delivery time, size according to discharge and hydraulic pressure, will determine the quality of per second transporting water earlier by test, determine time of delivery according to the gross mass of want transporting water then, this engineering determines that by testing carrying the time of 1600kg water is 68s.
(4) feed intake
Cement is filled it up with in cementing tank 1 the inside, and the self-measuring device parameter just can feed intake after setting and finishing.After in self-measuring device, pressing the discharging key, just can carry out the conveying of cement, after the weight that reaches setting, controller 6 control cylinders are opened Self controlling valve 15(and are controlled cement conveyer 3 simultaneously and stop feeding), cement is discharged in the agitator 13, unsnatch this cement after, again close Self controlling valve 15, carry out feeding intake next time, up to the gross weight that reaches setting (1600kg), system can stop the conveying of cement automatically.In the feeding process, if carry do not connect be used to or time of delivery longer, can start the vibrator 2 on the cementing tank 1, accelerate transporting velocity.Accurate for the cement quantity that guarantees to drop into, regularly demarcate self-measuring device, guarantee the accuracy that feeds intake.
When in agitator 13, carrying cement, press digital display time relay 7, in agitator 13, add water.After water adds 17s (i.e. 1/4th water yields), just can open first mixer 14 and carry out the stirring of cement mortar, after waiting to arrive the time of setting, water pump 8 stops to send water, finishes whole feeding intake.Control by the time because add water, so want the water in the running check bucket whether sufficient, avoid adding again in the water process water shortage in the bucket, cause the water metering inaccurate, thereby influence the quality of cement mortar.
(5) stir
After finishing the feeding intake of cement and water, first mixer 14 of opening agitator 13 tops stirs.After stirring the stipulated time, whether evenly stir for detecting, can check by measuring cement mortar proportion, when cement mortar proportion during near theoretical proportion, show then that cement mortar stirs to finish, can be used for constructing.When mix the cement mortar that makes put into deposit stock tank 9 after, for guaranteeing the uniformity of cement mortar, avoid condensing into piece because cement mortar leaves standstill for a long time, settle second mixer 10 on the top of depositing stock tank 9, stir mixing the cement mortar that makes, guarantee the cement mortar quality.
