Abstract
The utility model relates to a sealing device of a dewatering casing of a deep well, which comprises an iron cover covered on a casing, wherein the iron cover is fixed with the casing by a bolt, and a rubber gasket is connected between the iron cover and the casing. The utility model has the advantages that when the deep well is closed, the iron cover is fixed on the casing by the bolt and dose not need to be welded on the reinforcing steel bars of a foundation, the installation is easy, the manufacturing cost is low, and the rubber gasket connected between the iron cover and the casing ensures the good sealing performance.
Description
Technical field
The utility model relates to a kind of sealing device of deep-well precipitation sleeve pipe, particularly a kind of sealing device that the deep-well precipitation sleeve pipe simple, that cost is low is installed.
Background technology
Builing industry is removed diving deep well pump and gutter in the precipitation deep-well in work progress after; prefabricated gutter need be set; suppose draining; but stop to suppose draining for the needs that seal; just iron covering must be covered on deep-well; and around be welded on the reinforcing bar of ground concreting topping again with steel plate, but this traditional work method exists mounting cost and the too high shortcoming of cost.
The utility model content
The technical problems to be solved in the utility model provides a kind of sealing device that the deep-well precipitation sleeve pipe simple, that cost is low is installed.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of sealing device of deep-well precipitation sleeve pipe, comprise the iron covering that covers on sleeve pipe, its innovative point is: described iron covering is fixed by bolt and sleeve pipe, and is connected with rubber sheet gasket between described iron covering and sleeve pipe.
Advantage of the present utility model is: sealing is fixed on iron covering on the sleeve pipe by bolt during deep-well, need not iron covering is welded on the reinforcing bar of ground, installs simply, cheap, is connected rubber sheet gasket and has guaranteed good sealing property between iron covering and sleeve pipe.
Description of drawings
Figure is the sealing device of precipitation deep-well sleeve pipe of the present utility model.
The specific embodiment
As shown in the figure, the utility model relates to a kind of sealing device of deep-well precipitation sleeve pipe, comprise the iron covering 2 that covers on sleeve pipe 1, this iron covering 2 is fixed on the upper surface of sleeve pipe 1 by bolt 3, need not iron covering 2 to be welded on the reinforcing bar of ground, saved the sealing cost when improving sealing deep-well efficient with steel plate.For the sealing performance that guarantees to seal, we also have been connected the rubber sheet gasket 4 that increases sealing performance between iron covering 2 and sleeve pipe 1.
