Scene is secondary to mix and stir, if the slump of tank car inner concrete cannot still expire after any of the above-described working method is mixed and stirred
II frequency of frequency converter should be arranged according to the slump of concrete in sufficient construction requirement, so that motor II 602 reaches required revolving speed,
Additive is through 603 atomized spray of nozzle to concrete surface, and the linear adjustable extent of additive flow is 0-0.75L/min, herein
Additive be liquid that original additive and water are matched by a certain percentage, to by the secondary concrete mixed and stirred of additive again into
The measurement of row performance indicator after construction, should first close motor II 602 until reaching job specfication requirement.
The productivity of the concrete of different slumps, continous way oscillating mixer 5 is different, I frequency of initial setting up frequency converter
For 50HZ, according to stirring and material position situation of the concrete in continous way oscillating mixer 5, then the frequency of frequency converter I is adjusted
A certain determining value of the rate between 30-60HZ, while the frequency of corresponding adjustment frequency converter II is a certain true between 15-60HZ
Definite value.
In order to detect the performance after the present invention stirs the concrete after tank car transports with certain slump-loss,
It is each to the concrete test block that same tank car concrete acquisition mix is forward and backward three and to detect, Testing index include the slump,
Divergence, the emptying time of falling bucket and compression strength and corresponding intensity coefficient of dispersion take test block process mixed in strict accordance with country
Solidifying soil nature energy examination criteria carries out.Surveyed index result is as follows:
1 two continuous shaking stirring test construction workability comparisons of table
| The slump (mm) | Divergence (mm) | Rewinding emptying time (s) | |
| Before secondary vibration stirring | 110 | 210*200 | 7.45 |
| After secondary vibration stirring | 170 | 250*240 | 2.00 |
To be known by table 1, the slump, divergence of concrete after secondary continuous shaking stirring of the finished product concrete in tank car improve,
The emptying time of falling bucket is greatly decreased, and concrete construction workability is significantly improved, and the scene that can greatly reduce adds water construction
Probability, and the molding of vibrating of concrete is more conducive under equal conditions, improve the compactness of concrete.
2 two continuous shaking stirring test compression strength comparisons of table
Known by table 2, promotes 10% or so through live secondary agitation concrete crushing strength, tension variance reduces by 30% or more, mixes
Solidifying soil property amount is more uniform, effectively increases the durability of engineering and reduces the maintenance cost in later period.
