Description
Technical field
The utility model relates to drainage system of calming the anger, particularly a kind of freezing hole refrigerating medium retracting device.
Background technology
In Shaft Freezing engineering, after the construction of pit shaft inner layer well wall terminates, pit shaft no longer needs cold, at this moment Freezing Station stops cooling, freezing engineering is completed, carry out freezing equipment dismounting, if now do not carry out recovery to salt solution will bring impact, if be discharged into construction site to bring pollution to environment to freezing pipe backfill; Inclined shaft freezing engineering is freezed owing to adopting segmentation more by stages, determine to freeze order by tunneling direction, first the first driving section is freezed, circle time and driving speed is handed over to carry out the input of follow-up freeze section successively according to freezing, after leading portion driving terminates, just can extract feed pipe and carry out next section of construction, and when salt solution does not reclaim, directly will be discharged to pick block working face when pipe cutting, both progress was affected, again contaminated environment.
Usually adopt industrial brine (Cacl2) as refrigerating medium in construction freezing method, because freezing pipe caliber and high-lift diving pump volume limit, reclaim salt solution in freezing pipe to be difficult to realize in frozen construction, this reclaims just to shaft of vertical well refrigerating medium and inclined shaft driving and masonry construction brings many difficulties, for inclined shaft, because a large amount of freezing hole cuts off in pick block process, and wherein fill salt solution, not only affect construction speed, thawing forms frost wall, and when freezing hole is darker, because pressure is comparatively large, salt solution is easy to spray and hurts sb.'s feelings or spray bad equipment.
In the construction of traditional freezing shaft, the refrigerating medium after most of shaft construction in freezing hole does not reclaim, and after feed pipe reclaims, refrigerating medium is directly stayed in freezing pipe; In inclined shaft freezing construction, because part feed pipe will build section through pick, need freezing pipe to cut off in tunneling process, such refrigerating medium is directly discharged into pick and builds working face, bring certain workload and construction safety hidden danger to construction, make construction environment more severe simultaneously.
In pit shaft freezing construction, the tubing of the following caliber of freezing pipe many employings Ф 159mm, its internal diameter is less than Ф 140mm more, particularly inclined shaft freezing, owing to adopting partial freezing's mode, epimere large section of soil layer freezing pipe diameter is all less than Ф 127mm substantially more, and its internal diameter is just less.In being managed, salt solution immersible pump is discharged, pump housing diameter is very little, and the freezing hole degree of depth is much in 100m, the pump meeting this requirement is difficult to buy, and adds brine corrosion by force, good conductivity, higher requirement is proposed to pump housing material, sealing, appended cable quality, therefore, under current technical conditions, it is very difficult for using high-lift submersible pump to carry out freezing pipe salt Water Sproading.
