Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of this utility model embodiment.
Detailed description of the invention
The embodiment of a kind of plugging dewatering well constructing structure, in FIG, is provided with cylinder in its well body,
Being equipped with two retainer ring 2 on the inner hole wall of its cylinder 1, two retainer ring 2 are all to be wholely set with cylinder 1
, two retainer ring 2 intervals are arranged, and seal respectively on the top of two retainer ring 2 and are provided with shrouding 3, shrouding 3
The endoporus of retainer ring 2 is sealed up by diameter more than the diameter of bore of retainer ring 2, shrouding 3, and shrouding 3 passes through
The mode of welding is fixed in retainer ring.The periphery slip cap of cylinder 1 is provided with slip cap 4, and slip cap 4 can
To slide up and down relative to cylinder 1, the most uniformly it is hinged with bar shaped pressure-bearing in the lower end of slip cap 4
Plate 5, one end of bar shaped bearing plate 5 is hinged with slip cap 4, and the other end of bar shaped bearing plate 5 is hinged with and props up
Strut 6, one end of support bar 6 is hinged with bar shaped bearing plate 5, and the other end of support bar 6 is hinged on cylinder
On the outer wall of 1, slip cap 4, bar shaped bearing plate 5 and support bar 6 form slider-crank mechanism, are sliding
After dynamic set 4 moves down, bar shaped bearing plate 5 and support bar 6 are not on straight line, and both form one
Angle, at this moment, seals one water-stop sheet 7 of welding, water-stop sheet 7 and slip cap on the outer peripheral face of cylinder 1
The upper end top press-fit of 4, water-stop sheet 7 is on the base surface residing for the well head of well body.
In the upper port of cylinder 1, envelope is provided with hush panel 8, and hush panel 8 is weldingly fixed on cylinder 1.
Slip cap 4 and cylinder 1 are matched in clearance, are integrally convexly equipped with guiding on the outer peripheral face of cylinder 1
Bar, offers gathering sill on the inner hole wall of slip cap 4, and gib block coordinates with gathering sill slide-and-guide.
It is in the part between two retainer ring and retainer ring above section above pours at cylinder 1 endoporus
Concrete, and between the base surface residing for the well head of well body and water-stop sheet, set waterproof layer 10, exist simultaneously
Concrete layer 11 is set on waterproof layer 10 and gets final product water level lowering well sealing plugging construction structure, convenient and swift,
The successful enclosed of plugging dewatering well constructing structure with quick closure plugging dewatering well constructing structure, can be improved.
Meanwhile, bar shaped bearing plate forms a space with the support bar extruding construction well borehole wall, can be by sliding
Gap between dynamic set and cylinder injects waterproof material, such bar shaped bearing plate, support bar in this cavity
