From biologically, termite belongs to gregariousness incomplete metamorphosis insect.The microorganism that contains digestible cellulose in the stomach of termite, it is a foodstuff with timber and other plant.The kind of termite is a lot, mainly contain subteranean termites, damp-wood termite, dry-wood termite or the like, wherein subteranean termites and damp-wood termite are the bigger populations of harmfulness, the place of its perch and harm generally be moist, warm, foodstuff is sufficient, dark, improper ventilation, do not have or seldom have the environment of vibrations, the timber during their special happiness foods rot.Discover that further the timber water content was suitable for the termite survival activity most greater than 29% o'clock; The timber water content is lower than at 29% o'clock, and the activity of termite just greatly reduces; When the timber water content less than 18% the time, termite just can't survive.In view of the above, state such as the U.S. and Canada with light-duty wooden with the water content standard of dimension stock be decided to be≤18%.
According to the knowledge of the applicant, up to the present the means of domestic and international timber buildings control termites mainly are control timber water content.Although this method can play the better prevention effect, and be not easy operation, the control water content is a kind of measure after all, and it also can not reach the effect and the effect of " all-round " control termites.
Summary of the invention
Purpose of the present invention is exactly in order to solve above shortcomings in the prior art, and a kind of timber buildings, even more ideal method of control termites effect of being applicable to is provided.
Purpose of the present invention is achieved through the following technical solutions:
The method of timber buildings control termites is characterized in that: in the architectural process, substrate soil carries out drug treating over the ground, prevents that soil from occupying termite from underground invasion; And, on foot wall, overlay or anchoring one deck antiseptic insect-repelling sleeper.
Purpose of the present invention can also come further to realize by the following technical programs:
The method of above-mentioned timber buildings control termites, wherein, the method that the described soil of substrate over the ground carries out drug treating is, after ground excavates prescribed depth and cleans out, the sodium arsenite aqueous solution is sprayed in wall and bottom surface to foundation trench, and backfill soil is finished after the compacting, sprays decis suspension again.
Further, the method for above-mentioned timber buildings control termites, wherein, the weight concentration of the described sodium arsenite aqueous solution is 1.5%, spraying consumption is 10 gram/m
2The weight concentration of described decis suspension is 2.5%, and spraying consumption is 5 gram/m
2
Again further, the method of above-mentioned timber buildings control termites, wherein, described antiseptic insect-repelling sleeper is to use chromated copper aresenate to carry out antiseptic insect-repelling and handles later sleeper, and the weight of chromated copper aresenate consists of---copper sulphate 22%, sodium dichromate 33%, diarsenic pentoxide 45%.
Further, the method for above-mentioned timber buildings control termites, wherein, in the described antiseptic insect-repelling processing procedure, in the treatment fluid that is made into chromated copper aresenate, the weight concentration of chromated copper aresenate is 4～5%, processing procedure is an impregnating by pressure, and absorptive amount is 6～8 kilograms/m
3
The present invention is starting point with control termites to the harm of timber buildings, at subteranean termites and these two kinds of termite populations that harmfulness is bigger of damp-wood termite, the more satisfactory method of preventing and treating of a kind of effect has been proposed: carry out drug treating by substrate soil over the ground, can prevent effectively that soil from occupying termite from underground invasion; And, on foot wall, overlaying or anchoring one deck antiseptic insect-repelling sleeper, it is the connector between basis and the timber structure framework, is again the ground isolation barrier of one control termites.After this antiseptic insect-repelling sleeper was handled through the treatment fluid that contains chromated copper aresenate, wooden sex change not only can not be as the bait of mushroom, insect, and toxicity is big, and very strong sterilizing pesticide power is arranged.Therefore, adopt technical solution of the present invention can play the technique effect of good control termites.
Embodiment
Control termites is a great problem of building timber buildings.The present invention proposes: in architectural process, substrate soil carries out drug treating over the ground, prevents that soil from occupying termite from underground invasion; And, on foot wall, overlay or anchoring one deck antiseptic insect-repelling sleeper, can play good control efficiency.
Wherein, substrate soil carries out the method for drug treating and is over the ground, after ground excavates prescribed depth and cleans out, spray the sodium arsenite aqueous solution to the wall and the bottom surface of foundation trench, and backfill soil is finished after the compacting, sprays decis suspension again.
Sodium arsenite strong toxicity, drug effect reach 50 years.The weight concentration of the sodium arsenite aqueous solution commonly used is 1.5%, and spraying consumption in the use is 10 gram/m
2The weight concentration of decis suspension commonly used is 2.5%, and spraying consumption is 5 gram/m
