Abstract
The utility model relates to a well shutting sleeve of a dewatering well, which is composed of a steel sleeve and a clamping ring cover plate and characterized in that an inner water stop ring is welded in the steel sleeve; an outer water stop ring is welded outside the steel sleeve; the steel sleeve is sleeved on a dewatering well pipe and closed at the inner water stop ring of the steel sleeve by using the clamping ring cover plate; an expansion waterstop is cushioned between the inner water stop ring of the steel sleeve and the clamping ring cover plate; the steel sleeve disclosed by the utility model has the advantages of being convenient for installation and rapid for operation; the bottom plate structure and the well shutting quality can be ensured; and the problems that the underground water level is high and wells in areas with wealthy underground water are leakiness to shut can be solved.
Description
Technical field
The utility model belongs to the engineering field, and particularly the precipitation well shut-in well sleeve pipe in the foundation basic construction of high water level and underground water plentifulness guarantees that well casing does not seep water.
Background technology
Shut-in well technology to the precipitation well in the foundation basic construction of high water level and underground water plentifulness is at present: adopt the steel sleeve that has interior ring of sealing and outer shroud to be enclosed within on the precipitation well casing, adopt the interior ring flange of steel deck-plate and sealing to be connected.The shortcoming of this technology is: one, flange connect to need in sealing, to wear bolt hole on the ring and steel deck-plate, and this hole will become the main route of infiltration from now on.Two, this shut-in well technical operation is loaded down with trivial details, and to the big area of hydraulic pressure, water level rises too fastly during shut-in well, and compactness can not get guaranteeing.Job practices originally can not satisfy the shut-in well requirement in high water level and underground water area in plenty.
Summary of the invention
The purpose of the utility model provides a kind of precipitation well shut-in well sleeve pipe in order to overcome problem and the defective that prior art exists, and guarantees the shut-in well requirement in high water level and underground water area in plenty.
The utility model solves the technical scheme that its technical problem adopted:
Precipitation well shut-in well sleeve pipe; Form by ring, sealing outer shroud and snap ring cover plate in steel sleeve, the sealing; It is characterized in that: in steel sleeve, encircle in the welding sealing, at steel sleeve external welding sealing outer shroud, steel sleeve is enclosed within on the precipitation well casing; With snap ring cover closure ring place in the sealing of steel sleeve, and in the sealing of steel sleeve the ring and the snap ring cover plate between be lined with the expansion waterstop.
Described steel sleeve is identical with precipitation casing curvature and radian is consistent, just is enclosed within on the precipitation well casing and is advisable.
Ring curvature is identical and radian is consistent in the sealing of described snap ring cover plate and steel sleeve, just is placed in the sealing of steel sleeve to be advisable on the ring.
Offer annular groove and Pear-Shaped hole on the ring in the described sealing.
Described snap ring cover plate welding mushroom head and carrying handle, carrying handle is convenient to carrying, and the mushroom head is convenient to the snap ring cover plate is snapped in the Pear-Shaped hole of encircling in the sealing.
Before cushion construction, steel sleeve is enclosed within on the precipitation well casing, treat that structure construction is accomplished after; In the time of the sealing well casing, in steel sleeve, build ring place in concrete to the sealing, the place is provided with the expansion waterstop at the sealing outer annular recess; The snap ring cover plate is covered in sealing rotational fixation on the ring, improved the compactness of shut-in well sleeve pipe, expansion waterstop water-swellable; Shutoff infiltration route has guaranteed that well water can not ooze out base plate.
The utlity model has reasonable in designly, need not to drop into too much expense and just can solve the shut-in well problem in high water level and the underground water foundation in plenty, guarantee the shut-in well quality.
The utility model need under the various geological conditionss to be equally applicable to the precipitation well of shut-in well.
Description of drawings
Fig. 1 is the vertical view of the steel sleeve that has interior ring of sealing and sealing outer shroud of the utility model.
Fig. 2 is the vertical cross section figure of the snap ring cover plate of the utility model.
Fig. 3 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is carried out detailed explanation:
With reference to Fig. 1, Fig. 2, Fig. 3; The utility model by encircle 2 in steel sleeve 1, the sealing, sealing outer shroud 3 and snap ring cover plate 5 form, and in steel sleeve 1, encircles 2 in the welding sealing, at steel sleeve 1 external welding sealing outer shroud 3; Offer annular groove and Pear-Shaped hole 4 on the ring 2 in the described sealing; Steel sleeve 1 is enclosed within on the precipitation well casing, is enclosed in ring 2 places in the sealing of steel sleeve 1 with snap ring cover plate 5, welding mushroom 6 and carrying handle 7 on the described snap ring cover plate 5; Carrying handle 7 is convenient to carrying, and mushroom 6 is convenient to snap ring cover plate 5 is snapped in the Pear-Shaped hole 4 of ring 2 in the sealing; And in sealing, being lined with the expansion waterstop between ring 2 annular groove 8 and snap ring cover plate, described steel sleeve 1 is identical with precipitation casing curvature and radian is consistent, just is enclosed within on the precipitation well casing and is advisable.Ring 2 curvature are identical and radian is consistent in the sealing of described snap ring cover plate 5 and steel sleeve, just are placed in the sealing of steel sleeve to be advisable on the ring.
During shut-in well; Ring 2 places in concreting to the sealing are provided with the expansion waterstop in the annular groove 8 on the ring 2 in sealing in steel sleeve 1, snap ring cover plate 5 are covered again and in sealing, encircle on 2; Rotation snaps in the Pear-Shaped hole 4 of ring 2 in the sealing mushroom 6 and gets final product, and on snap ring cover plate 5, builds concrete.
