Abstract
The invention relates to an underground water pressure reducing valve, which comprises a steel cylinder, a steel ring, a rubber ring and a steel pressure plate, wherein one end of the steel cylinder is welded with the steel ring into a whole; the steel cylinder is placed in a metal filter screen in an underground drainage pit, and the steel ring is positioned above a concrete cushion layer of the underground drainage pit and embedded into a concrete bottom plate; and the rubber ring and the steel pressure plate are sequentially fastened on the steel ring through fasteners. The underground water pressure reducing valve is simple in structure, easy to manufacture, convenient to operate, strong in pertinence and easy to popularize.
Description
Technical field
The present invention relates to a kind of underground water decompressor that is used for underground draw-well construction, particularly relate to a kind of underground water reducing valve.
Background technology
When construct in the aquifer of general basis below groundwater table, adopt serial technology measure.In large-scale underground tank construction, construction will be provided with some draw-wells at the base plate position for ease, utilizes submersible pump to get rid of and draws water, and in work progress, draw-well is sealed.In the construction, take to get rid of to draw water more and in time build the method for concrete at present, but this method influences the quality of concrete easily.Therefore, need to adopt a kind of new simple structure, make easily easy to operate, with strong points underground water draw-well locking device: underground water reducing valve.
Summary of the invention
Technical problem to be solved by this invention provides a kind of underground water reducing valve, to solve constructional difficulties in the prior art, is difficult to operation, defect of high cost.
The technical solution adopted for the present invention to solve the technical problems is: a kind of underground water reducing valve is provided, comprises steel cylinder, steel ring, rubber ring and keeper plate of steel, an end and the said steel ring of said steel cylinder are integrally welded; Said steel cylinder is placed in the metal screen in underdrainage hole, and said steel ring is arranged on the concrete bed course in said underdrainage hole and is embedded in the concrete base plate; Said rubber ring and keeper plate of steel are fastened on the steel ring through securing member successively.
Coarse sand is filled up in said metal screen periphery.
Said securing member comprises screw bolt and nut; Said stud weld is connected on the said steel ring, and the bolt hole that is provided with said rubber ring and keeper plate of steel is corresponding each other.
Said bolt is outside equipped with the PVC protection sleeve.
Beneficial effect
Owing to adopted above-mentioned technical scheme; The present invention compared with prior art; Have following advantage and good effect: the present invention is a underground water draw-well locking device, and highly versatile is made simple; Solve the difficult problem of underground water draw-well sealing with lower cost, eliminated the hidden danger of influence on groundwater concrete quality.Simple structure is made easily, and is easy to operate, with strong points, promotes easily.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is an application sketch map of the present invention.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used to the present invention is described and be not used in the restriction scope of the present invention.Should be understood that in addition those skilled in the art can do various changes or modification to the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment of the present invention relates to a kind of underground water reducing valve, and is as shown in Figure 1, comprises steel cylinder 1, steel ring 2, bolt 3, rubber ring 4 and keeper plate of steel 5.Steel cylinder 1 and steel ring 2 constitute the pre-buried part of reducing valve, and described steel cylinder 1 upper end is one with steel ring 2 welderings, and several bolts 3 are welded on the steel ring 2 in advance, and the bolt hole of reservation is corresponding each other on the position of bolt 3 and rubber ring 4 and the keeper plate of steel 5.The cover plate part of rubber ring 4 and keeper plate of steel 5 formation reducing valve utilizes nut can rubber ring 4 and keeper plate of steel 5 be fastened on the steel ring 2 through several bolts 3.
As shown in Figure 2, in the underground hole that draws water of deep foundation ditch, at first place metal screen 6, around metal screen 6, fill up coarse sand 9 then and be used for infiltration.2 welderings are one to steel cylinder 1 with steel ring, and several bolts 3 are welded on the steel ring 2 in advance, and bolt 3 is provided with the PVC protection sleeve in order to the protection screw thread, is placed on then in the metal screen 6 in underdrainage hole.Steel ring 2 is arranged on formation draw-well in back on the concrete bed course 7, and draw-well is used for the submersible pump draining.Steel ring 2 is embedded in the concrete base plate 8 when building concrete base plate 8.After treating that concrete base plate 8 reaches intensity, can seal the underground water reducing valve.At first drain and draw water, in steel cylinder 1, fill rubble then, utilize nut and several bolts 3, rubber ring 4 and keeper plate of steel 5 are fastened on the steel ring 2, reach and isolate phreatic purpose.
Be not difficult to find that the present invention is a underground water draw-well locking device, highly versatile is made simply, has solved the difficult problem of underground water draw-well sealing with lower cost, has eliminated the hidden danger of influence on groundwater concrete quality.Simple structure is made easily, and is easy to operate, with strong points, promotes easily.
