Background technology
Suspension roof support because its supporting effect is good, materials province, low cost, the strong applicability to the soil layer in place, construction is simple,
Be conducive to that mechanized operation, speed of application be fast, the place needed for construction is smaller, can be close to the advantages that existing building excavates,
So using quite varied, such as：During massif tunnel excavation, lithospheric loosening generally can all occur, it is necessary to use anchor pole
Supporting；When grade of side slope is larger, also need to use suspension roof support；The excavation of deep basal pit, it is most of also to have used suspension roof support,
Etc..The shortcomings that use scope just because of suspension roof support is more and more wider, suspension roof support more can not be ignored, most importantly
The corrosion problems of anchor pole, it is heavy then may make because the problem of corrosion condition of anchor pole would generally cause security and durability
Into the extensive disaster such as building collapsing, landslide.
The main reason for causing anchor pole to corrode is chemical composition and the corrosiveness of underground water in the soil body, is especially worked as in the soil body
There are that can greatly accelerate corrosion when sodium salt, calcium salt and magnesium salts, the reason is that the solubility of these salt is high, easily by the moisture in stratum
Solution forms electrolyte, and the condition of electrochemical corrosion is provided for anchor pole；In addition when other corrosive mediums, it can also cause anchor pole rotten
Erosion.Therefore, anchor pole corrosion-resistant major measure is exactly to completely cut off anchor pole to contact with the soil body, the direct of underground water.
At present, for the corrosion of anchor pole, people also use the measure of many, as thermal shrinkage type protection tube, slip casting are protected
Deng.Although these measures have all achieveed the purpose that anticorrosive property, when such as using casing pipe protection, casing can not be used repeatedly,
Cause cost increase, environmental pollution, work progress complicated；Such as using slip casting protection when, due to cement mortar itself there is it is micro-
Fine pore, over time, the infiltration of underground water slowly, when underground water contacts anchor pole, anchor pole will corrode.Cause
This, develops a kind of reliable isolation underground water and the soil body and the repeatable casing bit utilized, and combine casing pipe protection and slip casting
The anchor pole anticorrosion construction method of protection a little becomes urgent problem to be solved.
