Description
Technical field
The utility model relates to building field, relates in particular to the method for blocking of basement deep-well.
Background technology
Large Foundation Pit, after construction of bottom plates finishes, must carry out shutoff to downcast well pipe, to guarantee the underground water chamber that do not permeate the ground.Conventional way is to adopt steel deck-plate welding plugging method.Before shutoff downcast well pipe, all water pumps are cut off, sent special messenger to examine the accurate speed (being available weld interval) that every a bite Well Water Level goes up, and carry out corresponding record, map out welding machine number of units and operative employee's number.General welding a bite well casing one individual demand 13 minutes, can first start steel deck-plate welding shutoff from the large well casing of the water yield according to the actual conditions of on-the-spot water level rise speed, to finally staying the shutoff simultaneously of 4-6 mouth well casing.A bite well casing can two people weld simultaneously, and the fastest 6-7 minute has welded.Steel deck-plate welding shutoff refers to direct weldable steel cover plate in water-stopping steel sleeve, and then on steel plate, builds the impervious concrete that adds a high grade strength of micro-swollen dose.This method requires the time that groundwater table goes up to be at least greater than 7 minutes, and requires two skilled welders construction simultaneously that cooperatively interacts, thereby has certain limitation.
If last reserved 4-6 mouth well casing water level rise speed is less than 7 minutes, the method that consideration adopts the short plug of steel plate strip or valve shutoff to combine is carried out.On steel bushing blank cover, increase the short silk of weldering Ф 100, in short silk, can wear water pipe, in welding, can ceaselessly draw water during with the cover plate of screw thread, after steel deck-plate welds, water pipe can be cut off from screw thread, at once plug is sealed, then build the impervious concrete that adds micro-swollen dose of high grade strength, so just can solve the water level problem that goes up fast, but require the sealing of screw thread necessarily will get well, the submersible pump in well casing also cannot take out simultaneously.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and the basement deep-well that a kind of plugging effect is good, efficiency is high plugging device is provided.
The purpose of this utility model is achieved in that a kind of basement deep-well plugging device, comprise well casing, the top of described well casing arranges the first steel bushing, the first seal ring is welded in the lower end of the first steel bushing, the second seal ring is welded in the upper end of the first steel bushing, and the second steel bushing is welded in the top of the second seal ring; In described well casing, place steel pipe, the lower end surrounding of steel pipe radially arranges water seepage hole, and the water inlet end of steel pipe and water seepage hole place parcel screen pack arrange cobble packed layer between steel pipe and well casing; On steel pipe, place the first steel deck-plate and the second steel deck-plate, the first steel deck-plate welds mutually with described the first seal ring, the first steel deck-plate is arranged on the top of well casing, the second steel deck-plate welds mutually with described the second seal ring, the upper end of steel pipe passes the second steel bushing, on the steel pipe in the second steel bushing, connects high pressure valve; The first fiber slightly expanded concrete layer is set between described the first steel sleeve and steel pipe, the second fiber slightly expanded concrete layer is set between described the second steel sleeve and steel pipe; Described plugging device also comprises and is laid on ground foundation pad; foundation pad is arranged on the periphery of well casing upper end; coating waterproof layer is set above foundation pad; fish tail and waterproof layer is set above coating waterproof layer; fish tail and waterproof layer is arranged on the periphery of the first steel bushing; sole plate is set above fish tail and waterproof layer, and sole plate is arranged on the periphery of the first steel bushing and the second steel bushing.
The utility model preparation method is: 1, steel bushing is made: steel bushing is made by thick 6mm steel plate, and its internal diameter is 600mm, highly for sole plate thickness adds 40mm; In the middle part of steel bushing and bottom, outside one thickness of welding is 6mm, and external diameter is the seal ring that 632mm, internal diameter are 580mm.
2, steel bushing is pre-buried: after the construction of sole plate concrete cushion, before construction of waterproof layer, steel bushing is installed above well casing, and with 40mm cover concrete, steel bushing is pre-buried.
3, well casing shutoff: well casing shutoff is sequentially the low absolute altitude of first shutoff place well casing shutoff high standard eminence well casing again, gathers to center from foundation ditch surrounding.Before well casing shutoff, outsourcing screen pack first punches steel pipe surrounding, diameter 50mm steel pipe is positioned among well casing and with cobble and is backfilled to steel bushing bottom, then by diameter 50mm steel pipe through steel deck-plate (thickness is 6mm, and diameter is 590mm) centre and with seal ring surrounding firm welding.The delivery port of steel pipe docks with self priming pump.
4, in steel bushing, build fiber slightly expanded concrete to middle seal ring, second steel deck-plate (thickness is 6mm, and diameter is 590mm) is installed, and firm with the welding of seal ring surrounding.
5, close 1.5 cun of high pressure valves, in steel bushing, build fiber slightly expanded concrete to sole plate upper surface, the unnecessary steel pipe in excision top, dimension slightly expanded concrete can be strengthened antiseepage function.
The utility model is by above design, and simple, convenient, shutoff efficiency is high, good seepage-proof property, and the phenomenon that can avoid the submersible pump in well casing also cannot take out.
