Description
Technical field
This practicability category technical field of concrete material test, in particular to a kind of concrete are rapidly saturated device and saturation
Method, suitable for the saturated process before the freeze proof anti-permeability performance test of concrete material.
Technical background
With the rapid development of the civil engineering industry in China, concrete is answered as a kind of important structure composition material
With extensive, such as road, bridge, Fang Jian, water conservancy industry.The material property of concrete is also widely paid attention to, many scholars
To fully realize concrete material characteristic, various durability tests are carried out to it, include the paddle impermeability of concrete, freeze thawing
The frost resistance etc. of concrete in environment.Before carrying out the above durability test to concrete, it is required to be saturated material
Processing.Currently used concrete saturation mode has infusion method, takes out and press saturation etc., these methods have it under certain conditions
Itself the advantages of, infusion method are easy to operate, it is only necessary to be placed in water sample and flood, but it is mark that 4d is impregnated in its general requirement
Standard, not only cycle time is long, but also not can guarantee sample interior and reach saturation.Taking out pressure saturation is taken out in concrete sample side
Vacuum is taken, air present in hole is taken out of, the other side makes its infiltration, although sample interior can be reached certain by the method
Vacuum state, but the osmotic gradient formed is smaller, and peak suction value is 10m head, and normal condition is also unable to reach
Absolute vacuum state, although ensure that full water degree, its full water speed rate is slower, and the sample being rapidly saturated for needs increases
It is saturated the period, is unfavorable for the progress of test.Therefore, there is an urgent need to a kind of quicker, stable concrete saturation devices.
Utility model content
This practicability is the technical problem to be solved is that providing a kind of concrete sample to be rapidly saturated device, to fast implement
The saturation of concrete sample solves the problems, such as that the prior art saturation period is long, is difficult to ensure degree of saturation.
Technical solution used by this practicability is:
A kind of concrete is rapidly saturated device, including water container, and the water container top passes through conduit and air compressor machine
It is connected, pressure regulator valve and the first valve is provided between water container and air compressor machine, the water container bottom passes through the second valve
It is connect with pedestal, the upper end of the pedestal is connect by bolt with the sample container for placing sample, and the sample periphery is cased with cream
Glue film, the sample container side are equipped with round ozzle, and the ozzle is connect with air-breathing ball, and the sample container top passes through spiral shell
Bolt is connect with top cover, and the top cover upper end opening is connected by conduit with vacuum pump, and third valve is arranged between top cover and vacuum pump
Door.
Further, the cavity formed between connection latex film and sample container on the inside of the ozzle, outside separate type connect
Connect air-breathing ball.
Further, the latex film exceeds sample edge up and down.
Further, the sample container, sample, top cover, pedestal are cylindrical type.
Further, the water container and sample container use clear PVC material.
The method that concrete sample is rapidly saturated is carried out using the device to include the following steps: to be taken out with air-breathing ball by ozzle
Air between sampling container and latex film places sample in sample container, and loose from air-breathing ball, sample is tightly attached to latex film
In, then pass through the bolt seal whole device of symmetric design；Third valve is opened, starts vacuum pump, opens simultaneously the first valve
Door and the second valve start air compressor machine, by adjusting the size of pressure regulator valve, control pressure size；To droplet occur at the top of sample
Shape, saturation are completed.
A kind of concrete that this practicability provides is rapidly saturated device, compared with prior art, has the following advantages that and imitates
Fruit:
1, sample side is evacuated using vacuum pump, inside concrete hole micro-bubble can be excluded completely, at entirety
In vacuum environment, be conducive to liquid water and infiltrated from bottom end, reaches fully saturated and infiltrate purpose.
2, concrete sample is made to be rapidly achieved saturation state in such a way that vacuum pump pumping is in conjunction with pressure water injection, not only
Sample saturation time can be shortened and can guarantee the degree of saturation of concrete sample.
3, it when progress concrete sample is installed on sample container, is drawn between sample container and latex film using air-breathing ball
Air, the space inside fine-tuning latex film greatly facilitates the operating process of sample placement.
Detailed description of the invention
