Abstract
The invention belongs to the technical field of well plugging of dewatering wells, and particularly relates to a novel flanged disc type well plugging sleeve which comprises a steel sleeve A, wherein a water stopping wing ring is arranged on the outer side surface of the steel sleeve A, a steel ring is welded on the inner wall of the middle of the steel sleeve A, a steel sleeve B is welded on the ring direction of the steel ring, a flange disc is welded on the upper end surface of the steel sleeve B, a steel cover plate matched with the flange disc is fixed on the flange disc through bolts, and the upper end surface of the steel cover plate is lower than the upper end surface of the steel sleeve A. The well sealing sleeve can make the water pump repeatedly used, so that the cost is saved; welding is not needed, and the well sealing efficiency is high; the fixed cover plate is used for primary well sealing, concrete is poured for secondary well sealing, and the dual well sealing ensures the well sealing quality.
Description
Technical Field
The invention belongs to the technical field of dewatering well sealing, and particularly relates to a novel flanged disc type well sealing sleeve.
Background
The conventional structure that precipitation well shut-in adopted mostly makes the water pump can not take out from the well, and the water pump can not reuse, causes the waste. At present, a well sealing structure capable of taking out a water pump from a well exists, but other procedures such as welding are needed, the well sealing efficiency is low, and the follow-up quality cannot be guaranteed.
Disclosure of Invention
The invention aims to overcome the defects of the background technology and provide a novel flanged disc type well sealing sleeve.
The invention is realized by the following technical scheme: the utility model provides a novel flanged disc type well plugging sleeve, includes steel sleeve A, is equipped with stagnant water wing ring at steel sleeve A lateral surface, a steel ring of steel sleeve A's middle inner wall welding, steel sleeve B welds on the steel ring hoop, and steel sleeve B internal diameter equals with steel ring internal diameter, welds the flange dish on steel sleeve B up end, the flange dish external diameter is greater than steel sleeve B external diameter, and the steel apron that the flange dish matches passes through the bolt fastening on the flange dish, and the up end of steel apron is less than steel sleeve A up end.
And a rubber gasket is arranged between the flange plate and the steel cover plate.
The length of the steel sleeve A is 1m, and the wall thickness is 10 mm.
The inner diameter of the steel sleeve B is 20cm, and the wall thickness is 10 mm.
The inner diameter of the flange plate is 20cm, and the outer diameter of the flange plate is 32 cm.
The distance between the upper end surface of the steel cover plate and the upper end surface of the steel sleeve A is 15-20 cm.
The well-sealing sleeve can make the water pump recycled, thereby saving the cost; welding is not needed, and the well sealing efficiency is high; the ring flange is less than whole telescopic height, and fixed steel cover plate carries out a shut-in, and concrete placement carries out the secondary shut-in, and dual shut-in has guaranteed the quality of shutting-in.
Drawings
FIG. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a partial structural schematic diagram of the present invention.
In the figure, a steel sleeve A is 1, a water stop wing ring is 2, a steel ring is 3, a steel sleeve B is 4, a flange plate is 5, a steel cover plate is 6, and a rubber gasket is 7.
Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to FIGS. 1-2, the invention comprises a steel sleeve A1, preferably steel sleeve A1 having a length of 1m and a wall thickness of 10 mm. The water stop wing ring 2 is arranged on the outer side surface of the steel sleeve A1. A horizontal steel ring 3 is welded on the inner wall of the middle position of the steel sleeve A1, and the inner diameter of the steel ring 3 is 20 cm. The steel collar ring 3 is welded with a steel sleeve B4 upwards, the steel sleeve B4 is positioned in the middle of the steel collar ring 3, and the inner diameter of the steel sleeve B4 is 20cm, and the wall thickness is 10 mm. And a flange plate 5 is welded on the upper end face of the steel sleeve B4, the inner diameter of the flange plate 5 is 20cm, the outer diameter of the flange plate 5 is 32cm, and the outer diameter of the flange plate 5 is larger than that of the steel sleeve B4. And the rubber gasket 7 and the steel cover plate 6 are matched with the flange plate 5, bolt holes consistent with the flange plate 5 are formed in the steel cover plate 6, the rubber gasket 7 is placed on the flange plate 5, the steel cover plate 6 is placed on the rubber gasket 7, and then the steel cover plate 6 and the rubber gasket 7 are fixed on the flange plate 5 through bolts. The steel cover plate 6 is positioned in the steel sleeve A1, namely the upper end face of the steel cover plate 6 is lower than the upper end face of the steel sleeve A1, preferably, the upper end face of the steel cover plate 6 is lower than the upper end face of the steel sleeve A1 by 15-20cm, and secondary well sealing by concrete pouring is facilitated.
After the cushion layer construction is finished, breaking the pipe well to 0.5-0.8m below the height of the top of the bottom plate, sleeving the pipe well with the well sealing sleeve, fixing the well sealing sleeve by using a steel bar, quickly lifting a water pump out of the well when the dewatering well is sealed, quickly covering the rubber gasket 7 and the steel cover plate 6 on the flange plate 5, screwing the rubber gasket and the steel cover plate 6 by using a bolt, and pouring bottom plate concrete to fill the operation surface to the top of the bottom plate after the steel cover plate 6 is sealed, so that double well sealing is realized.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; those of ordinary skill in the art will understand that: the technical solutions described in the above embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
