Description
Technical field:
The utility model belongs to armored concrete professional skill field, relates to a kind of for mass raft foundation dewatering wellSteel sleeve.
Background technology:
In the mass raft foundation construction of present stage, generally all to steel sleeve be set in mass raft foundation and meetNormal continue precipitation, do not destroy the functions such as well casing (as shown in Figure 1) when facilitating follow-up shutoff and building. Conventional steel sleeve at presentDevice (as shown in Figure 2):
Although conventional steel sleeve device does not destroy well casing and meets the normal precipitation function aspects that continues in the time that solution is builtPlay effect, but had following shortcoming in the time of shutoff dewatering well:
1, in the time of the shutoff of high water level area, easily form penetrating passage along tube wall and cause waterproof shutoff failure. And secondary placeReason difficulty is large, and cost is high.
2, can only be applicable to the poor one-time-concreting method for blocking of waterproof plugging effect or the little occasion of groundwater run off, application modelEnclose narrowly, waterproof shutoff is of low quality.
3, large, the unsuitable mechanization of middle bolt shape stopper size is fastening, efficiency is low, and interstitial hole is draining and grouting operationHole screw thread protection difficulty.
Summary of the invention:
The purpose of this utility model is to provide a kind of steel sleeve for mass raft foundation dewatering well, and this steel sleeve is anti-Water seal is stifled effective, after-treatment is convenient, cost is low, be applicable to the occasion that level of ground water is higher, the water yield is larger, and is applicable to machineryChange operation.
As above design, the technical solution of the utility model is: a kind of steel sleeve for mass raft foundation dewatering well,It is characterized in that: comprise body, outer wall seal ring, two inwall seal rings, be shaped with the end flange of screwed hole and be shaped with boltConnect the end closure plate of via hole; Outer wall seal ring is welded in tube wall, and two inwall seal rings are welded in respectively inboard wall of tube bodyBoth ends, the end flange that is shaped with screwed hole is welded in the upper end of body, being shaped with bolt, to connect the end closure plate of via hole logicalCrossing fastening bolt is fixed in end flange.
Above-mentioned body is the weldable steel pipe fitting of one end with groove.
Above-mentioned outer wall seal ring is annular steel plateelement, and internal ring portion position arranges bevel for welding.
Above-mentioned inwall seal ring is annular steel plateelement, and outer shroud position arranges bevel for welding.
The utlity model has following advantage and good effect:
1, the utility model, by weld inside and outside seal ring on steel sleeve, efficiently solves at high water level, water yield the earthDistrict forms along the penetrating passage of tube wall in shutoff process, thereby has improved shutoff quality, reduced after-treatment cost, raisingEfficiency.
2, the utility model is by adopting flange and closure plate bolt integrated connection, when raising mechanization is fastening, alsoCan in steel sleeve, carry out other operations because the whole mouth of pipe before shutoff does not seal, thereby can realize multiple tracks shutoff, ensure anti-Water plugging effect.

Detailed description of the invention:
As shown in Fig. 3-1, Fig. 3-2: a kind of steel sleeve for mass raft foundation dewatering well, outside welded still pipe 4Wall middle part welding outer wall seal ring 7, twice inwall seal ring 8 be welded in respectively the both ends of inboard wall of tube body, is shaped with screwed holeEnd flange 9 is welded in the upper end of body, and the end closure plate that is shaped with bolt connection via hole is fixed on end by fastening boltOn flange.
The utility model patent making step is as follows:
1, processing and fabricating welded still pipe and seal ring parts:
As shown in Figure 4: processing and fabricating steel sleeve body and seal ring parts, steel sleeve body is the weldering of one end with grooveConnect steel pipe fitting 4. As shown in Fig. 5-8: seal ring is divided into outer wall seal ring 7 and two inwall seal rings 8, outer wall seal ring and twoInwall seal ring is annular steel plateelement, and wherein outer wall seal ring 7 internal ring portion positions arrange bevel for welding, outside inwall seal ring 8Ring portion position arranges bevel for welding.
2, processing and fabricating cannula tip flange and cannula tip closure plate parts:
