Description

A kind of experimental rig

Technical field

The utility model belongs to construction material experimental technique field, is to be related to a kind of experimental rig more specifically.

Background technology

In modern construction, concrete durability is built railway, highway, Fang Jian, water conservancy, electric power, harbour etc. are each If field is more and more paid attention to.And in the durability test method of concrete, foundation《Concrete durability experiment Method》(GB/T 50082-2009), Testing Resistance of Concrete To Sulfate are that detection time is most long, people are needed to require efforts most More detection projects, detection time are at most needed 150 days, it is necessary to all be impregnated (15h) to concrete sample daily, air-dried (1h), drying (6h), cooling (2h) such a operation circulation.

Existing technology simply simply combines baking oven, water tank and water pump, along with a compressor for refrigeration A Testing Resistance of Concrete To Sulfate case is just constituted, although this equipment can realize automatic soaking, air-dry, drying, But the instrument has following several big shortcomings：1. function is single.Testing Resistance of Concrete To Sulfate can only be carried out, can not be collected Expect other sulfate soak tests such as robustness；2. the instrument can only increase test specimen newly in daily specific time and (each cycle Cooling time), so there is a strong possibility causes test specimen to cancel due to other fortuitous events make the test specimen that need to be tested overage phase；3. wave Take resource.When experiment quantity is few, instrument also can only be according to maximum power operation, and the drug needed for preparation cannot be reduced, This can undoubtedly cause the waste in many resources；4. the devices such as water pump, heater contact directly testing liquid, failure is increased Occurrence probability with when the excessive contact of the solution non-test environment caused by error；5. error is larger.In experiment impregnation stage knot Shu Hou, solution can discharge chamber, and immersion next time is waited to start to re-inject.Solution temperature can change to and outside during this Environment temperature is consistent, at this moment if external temperature is too high or too low, along with amount of solution is larger (generally in 0.3~0.4m³It is left It is right), when solution re-injects chamber and starts to impregnate at this time, more than ten minutes are just had to the temperature of the time solution of a hour Test requirements document is unable to reach, this just causes no small error to experiment；6. occupy other instruments equipment.It tries within two days before the test Part needs to dry two days with 80 ± 5 DEG C of temperature in an oven, and other experiments need the temperature dried to be generally 105 ± 5 DEG C, This is equivalent in two days of test specimen drying, which can not carry out other experiments, waste experiment resource.

Meanwhile in engineering construction, gather materials one index of anti-sulphates corrosive ability as reaction, the robustness gathered materials It is that in all types of engineerings although concrete possesses immersion and drying work(with the essential items for inspection that carry out type inspection of gathering materials, existing equipment Can, but the instrument has following three shortcoming：1. not only volume is larger for the quasi-instrument, but also can only carry out battery of tests every time, Do not possess the ability for being carried out at the same time multiple batches of experiment；2. error is larger.After impregnation stage is tested, solution can be drained into molten Liquid hutch waits immersion next time to start to re-inject.But because solution hutch does not have temperature regulating power, in sample Solution temperature can change to consistent with ambient temperature during drying, and at this moment if external temperature is excessively high, solution re-injects Chamber start impregnate when, it is possible to have more than ten minutes even dozens of minutes time solution temperature be unable to reach experiment will (soaking time of gathering materials every time ability 4h) is asked to cause very big error to experiment；Because solution is saturated solution used in experiment, if molten Liquid temperature degree reduces, the problem of may result in solution and crystallized in hutch, be so not only present with Crystallization Plugging pipeline, Er Qiehui Occur that experiment is caused the serious consequence of maximum error occur due to the solution concentration after crystallization reduces；3. instrument event easily occurs Barrier.Since the devices such as water pump, water pipe, heating tube, cooling tube contact directly sodium sulphate saturated solution, these devices easily occur because The failure or even scrap instrument that hydrops crystallizes and corrosion is caused.

Likewise, railway ballast, rock, ground tough test in, be also all not equipped with full-automatic, multiple batches of while try The equipment for testing ability.So existing equipment due to that cannot provide different environment temperatures simultaneously, it is impossible to be carried out at the same time multigroup or more Kind experiment.
