Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figs. 1-5, present embodiments provide it is a kind of evaluation pump concrete working performance device, including charging basket 3,
Isolation sieve bucket 2 and slump bucket 1,3 open top of charging basket, charging basket 3 madial wall be provided with scale for measuring sieving amount, isolate
The diameter for sieving bucket 2 is identical as the diameter of charging basket 3, and the open top of isolation sieve bucket 2, bottom are square hole screen 21,21 center of square hole screen
It is provided with plectane 22, isolation sieve bucket 2 is arranged on charging basket 3；Slump bucket 1 is up big and down small truncated cone-shaped and slump bucket 1
Top and bottom are open, the big a diameter of 200mm of mouth, a height of 300mm, and osculum diameter inclines depending on detection concrete type
8 °~10 ° of rake angle；The top of slump bucket 1 is provided with handle, and pressure stopwatch instrument 11, pressure stopwatch instrument 11 are provided on handle
Precision is less than 0.1s, and slump bucket 1 is separable to be shelved on plectane 22.
The purpose that slump bucket 1 is put on plectane 22 is that concrete mix is enable to fill slump bucket 1, is carried again after filling
It plays slump bucket 1 and tests flow time；After lifting slump bucket 1, concrete mix meeting on plectane 22 and square hole screen 21
Variant (passing through standing or effect of vibration), thus analyzes the sieving amount in barrel.Concrete mix after stream is empty
It directly is recovered to charging basket 3, it is small not will produce waste material, follow-up work amount.
3 top of charging basket is provided with spring hitch 31, can fix the weight more than 15kg；The lower part of isolation sieve bucket 2 and charging basket 3
Top is connected by spring hitch 31, and spring hitch 31 can be fixedly connected with the weight of 15~20kg.
In the present embodiment, the 5~10mm of the length of side in the hole of square hole screen 21, the 21 center covering of square hole screen one a diameter of 100
The plectane 22 of~110mm.3 size of charging basket is diameter 200mm, high 100mm；Isolation sieve 2 size of bucket is diameter 200mm, high
200mm。
The specifically used step of the device of this evaluation pump concrete working performance is：
1) charging basket 3 is connect with isolation sieve bucket 2 by spring hitch 31；
2) slump bucket 1 is positioned on the plectane 22 at 21 center of square hole screen；
3) concrete mix sampling to be detected will be pumped and fills slump bucket 1, stand 10~20s；
4) lift the slump bucket 1 for filling concrete mix by handle, pressure stopwatch instrument 11 starts timing, works as mix
Logistics is most, and pressure stopwatch instrument 11 stops timing, and reads；
5) 2~3min, or vibration manually are stood in isolation sieves bucket 2 from the concrete mix flowed out in slump bucket 1
It 15~25 times, observes its state and unloads isolation sieve bucket 2, estimate sieving amount.
The utility model basic principle：
It is evaluated using 1 pair of concrete viscosity of slump bucket, due to concrete viscosity difference, with certain gradient
Slump bucket 1 in, concrete flow time has larger difference (poor compared with viscous mobility its flow time of concrete
It is longer)；Concrete flows into isolation sieve bucket 2, and under gravity or effect of vibration, concrete mortar will have certain point with aggregate
From sieving amount can directly evaluate agent on crack resistance of concrete isolation performance.
Mixture flow time is measured using pressure stopwatch instrument 11, starts pressure stopwatch instrument 11 when lifting under Gravitative Loads
Start timing, when stream is empty, pressure stopwatch instrument 11 is automatically stopped timing when pressure is less than certain value A (pressure value A can be set), stops
The time recorded when timing is mixture flow time；Test only needs a people can be completed, easy to operate.
Pressure value A is set as：1 weight of slump bucket+(0.5~1) kg.The reason of such setup pressure value is：
When 1, there was only 0.5~1kg in last bucket, the time is flow to end less than 0.1s, completely within the scope of counting error；
2, pressure is set as bucket weight+(0.5~1) kg, and when stopping counting, slump bucket 1 has light, shows its mixture
It is empty stream has been considered as.
Flow time can be directly read using utility model device, flow time is corresponding with viscosity, and sieving amount can be sentenced
Disconnected agent on crack resistance of concrete segregability, sieving amount reading is higher, and education resistance is poorer, be easy to cause plugging.
Entering pumping hole using the device and going out pumping hole test flow time and education resistance, it is only necessary to a diameter of 200mm's
Entirely band can be placed, and be not strict with to place, and CN201320144818.1 at least needs a diameter of 2400mm's
Flattened region can just place, and requirements of the CN201320144818.1 to place is stringenter.
It should be understood that above-described embodiment is merely to illustrate the utility model rather than limitation the scope of the utility model.This
Field technology personnel after reading the content taught by the present invention, can make the utility model various changes or repair
Change, without departing from the spirit and scope of technical solutions of the utility model, the claim model in the utility model should all be covered
In enclosing.
