Description
Technical field
The invention belongs to concrete construction fields, and in particular to a kind of to prevent coagulation based on what water recycled the effect of micro- infiltration
The apparatus and method of soil cracking, suitable for preventing highlands concrete surface from crack occur.
Background technique
Distress in concrete is common one of the disease of concrete structure, and Producing reason is multifarious.Crack is to coagulation
The extent of injury of building is different.For the workshop mass concrete of highlands construction, since highlands is dry,
Strongly, the average annual evaporation capacity of many years is 2075.2mm to windy and daytime sunshine.Under such natural environment, concrete exists
After the completion of pouring, the moisture on surface is distributed quickly, and volume contraction is big, and internal humidity varies less, and volume contraction is just small, this
Sample surface deformation just will receive the effect of contraction of inner concrete, forms tensile stress, is very easy to cause the cracking of concrete.Together
The temperature change of sample amplitude may be merely creating surface layer crack interiorly, and in high principle, there may be crosscutting concerns.Therefore,
This must be paid attention to, and take measures to solve.
The measure of the existing control critical eigenvalue mainly packing material in crack, which carrys out control critical eigenvalue, further to be developed.But due to height
Original area's height above sea level, day and night temperature is big, dry and rainless, and most of highlands year-round average temperature at 0 degree hereinafter, it is this badly
The material that environment is easy to cause repairing to use is unable to normal cure, cannot normally improve the intensity of patching material, while low temperature ring
The mobility of material reduces under border, influences construction efficiency.Due to this severe natural environment, the cost of patching material is more high
Expensive, common repairing technique has certain limitation, cannot reach expected repairing purpose.Importantly, most control
Measure processed is not all set about from the moisture content for improving surface, but is passively repaired after concrete surface generates crack
It mends, does not achieve the effect that treating both manifestation and root cause of disease.
Summary of the invention
The technical problem to be solved by the present invention is to provide one for existing concrete Crack Control above shortcomings
Kind recycles the apparatus and method for preventing concrete cracking of micro- infiltration effect based on water, and highlands building construction is prevented from source
