Description
Technical field
The utility model discloses a kind of selenolite and underground water to the erosion test model equipment of concrete, belongs to concrete
Technical field of construction.
Background technology
Concrete structure is to be widely used a kind of general structure type, but due to its structure itself and use environment
Feature so that there are serious endurance issues for concrete.The durability of concrete refer to concrete under active usage conditions
Resist the long-term ability for keeping intensity and complete appearance of effect of various destructive factors.
For a long time, concrete is most wide as purposes in civil engineering, one of maximum construction material of dosage, in last 100 years
Development in, intensity be continuously improved.But while proposing high intensity, the endurance issues of concrete structure are also more come
More of interest by people.People are always to be very durable material for concrete, until phase late 1970s prosperity state
Family just gradually finds that premature breakdown occurs in some environments in the infrastructure project originally built up.The coagulation in many cities in the U.S.
Earth foundation facilities engineering and port engineering build up after 20~30 years, or even in the period of shorter in occur as soon as deterioration.It is domestic most
Number industrial building needs overhaul after using 25~30 years, the building service life only 15~20 under harsh environment
Year.The use environment of civil buildings and public building is relatively preferable, can generally maintain 50 years or more, but the balcony of outdoor, canopy
Service life etc. outdoor component usually only has 30~40 years.The endurance issues of the infrastructure projects such as bridge, harbour are more
Seriously, since concrete cover to reinforcement is excessively thin and density is poor, many engineerings build up occur as soon as within latter several years steel bar corrosion,
Concrete cracking.Sea port dock was generally just cracked and flaked off because of concrete along muscle using 10 years or so, and overhaul is needed.
African Territories concrete structure durability is horizontal less than China and developed countries, and the selenolite geology that African Territories blazon
And great rodent underground water, concrete structure durability is had a serious impact, therefore, it is durable to improve concrete
Property, extend engineering service life, it is the key that building trade the Implement of sustainable development strategy to reduce repair reconstruction expenses to the greatest extent.

Pilot model apparatus, the device include babinet 1, wait for desiccation concrete 2, treatment water coagulation soil 3, gypsum case 4, water fender 5, water tank
6, pricker 7, needle plate 8, cylinder 9, cylinder piston 10 and plastic foil 11；The centre of babinet 1 is equipped with twice partition board, and babinet 1 is by twice
Partition board is divided into three parts, and the concrete of same model is separately placed the three parts in babinet 1, and the side of babinet 1 is to wait doing
Change concrete 2, the other side of babinet 1 is treatment water coagulation soil 3, and the centre of babinet 1 is former concrete, and former concrete is to wait for desiccation
The comparison of concrete 2 and treatment water coagulation soil 3 is with reference to concrete；Wait for that desiccation concrete 2 is in contact with gypsum case 4, gypsum case 4
Top be equipped with air inlet 4.1, the side of gypsum case 4 is equipped with air outlet 4.2, selenolite, selenolite is filled in gypsum case 4
It is in contact with desiccation concrete 2 is waited for；Treatment water coagulation soil 3 is connected with water tank 6；The outside of water tank 6 is equipped with water fender 5, water blocking
The centre of plate 5 is equipped with needle plate 8, and pricker 7 is equipped with side by side on needle plate 8；It is equipped with plastic foil between treatment water coagulation soil 3 and water tank 6
11；Needle plate 8 is connect with cylinder piston 10, and cylinder piston 10 is driven by cylinder 9.
The main innovation point of utility model device is：1) wind of the air inlet in gypsum case and air outlet composition cycle
Road, air duct are in contact with desiccation concrete is waited for；Selenolite and wait for the changes in contact situation of the desiccation concrete quilt in efflorescence
Analog record.
2) treatment water coagulation soil is isolated between water tank by plastic foil, and plastic foil is not before being punctured, treatment water
The hydraulic pressure of concrete and the hydraulic pressure of water tank are balanced；After meeting the pressure balance between water coagulation soil and water tank, lived by cylinder
Plug driving needle plate simultaneously drives pricker to puncture plastic foil, and the water and treatment water coagulation soil in water tank are contacted, and regimen condition is met in simulation
The erosion situation of change of lower treatment water coagulation soil.
3) wait for that desiccation concrete and treatment water coagulation soil are the concrete of same model, by with the former coagulation among babinet
The case where soil is compared, and then analysis waits for the weathering of desiccation concrete and treatment water coagulation soil and meets water erosion.
