Because the top of sleeve body 1 is sealed fast, stopped groundwater and gushed and to the possibility of elevartor shaft infiltration through the opening at sleeve body 1 top, guaranteed going on smoothly of foundation ditch construction.

The utility model provides an elevator shaft precipitation sleeve carries out more detailed introduction with specific embodiment below in the combination of the figure.

In a first embodiment of the invention, the structure of the elevator shaft precipitation sleeve is as shown in fig. 1, and comprises a cylindrical sleeve body 1 and a sleeve cover 2 which is matched and sealed with the top of the sleeve body 1. Particularly, sleeve cover 2 and sleeve body 1 have adopted flange joint's mode, and sleeve body 1's top is equipped with ring flange 5, and multiunit flange screw hole has evenly been seted up to ring flange 5's circumference, sleeve cover 2 be with ring flange 5 complex flange apron, set up the flange screw with ring flange 5 one-to-one in the circumference of flange apron, and the one-to-one here both includes the correspondence in quantity, includes the correspondence of position again. When the flange cover plate is aligned with the flange plate 5, the flange screw holes formed in the flange plate 5 are aligned with all the screw holes formed in the flange cover plate respectively, and the flange cover plate and the sleeve body 1 can be connected and fixed through the flange bolts 6.

Generally speaking, in order to improve the assembly speed of the flange cover plate, the flange bolts 6 are usually preset in the screw holes of the flange plate 5 and are welded and fixed with the flange plate 5, when the sleeve body 1 needs to be sealed, the flange screw holes of the flange cover plate are only required to be placed downwards for rotating the flange bolts 6, and then the flange cover plate is fastened by nuts.

In order to improve the sealing performance when the flange cover plate is matched with the sleeve body 1, an annular groove is formed in the lower end face of the flange cover plate and is used for being in contact and abutting with the sleeve wall at the top end of the sleeve body 1. Furthermore, a sealing gasket 4 is arranged between the flange cover plate and the sleeve body 1, and the size of the sealing gasket 4 is larger than the inner diameter of the sleeve body 1 and is also larger than the diameter of the annular groove. Therefore, when the top end of the sleeve body 1 is abutted to the annular groove, the sealing gasket 4 is pressed to be attached to the annular groove, and the sealing performance of the pull connection part is improved.

When the sleeve body 1 adopts the above-mentioned flange plate 5 and flange apron complex form, sleeve body 1 not only can set up to cylindricly, also can set up to other shapes such as square tube, and the setting of flange apron is ensured can to seal the top of sleeve body 1.

In a second embodiment of the present invention, fig. 2 is referred to for the arrangement of the sleeve body 1 and the sleeve cover 2. In the present embodiment, the sleeve body 1 and the sleeve cap 2 are screwed together. The outer wall at the top of the sleeve body 1 is provided with an external thread, the sleeve cover 2 is a sleeve-shaped cover body matched with the sleeve body 1, the sleeve cover 2 is provided with an external thread matched with the sleeve body 1, and the external thread and the sleeve body are connected through the thread in a screwing mode, so that the assembly sealing efficiency is further improved.

Further, still be equipped with annular seal ring 3 between sleeve body 1 and the sleeve lid 2, increase the leakproofness at sleeve body 1 top through seal ring 3, avoid the groundwater to gush and ooze from sleeve body 1 top.

In order to optimize the embodiment, the waterproof gasket and the waterproof gasket are made of materials which can expand when meeting water, and when the underground water gushes, the waterproof gasket and the waterproof gasket expand to form better sealing.

In the above embodiment, the water collection hole 8 is preferably opened in the side wall below the middle of the sleeve body 1. The periphery of the sleeve body 1 is further provided with a water stop ring 7, the water stop ring 7 is an annular blocking piece welded on the outer wall of the sleeve body 1, the water stop ring 7 extends outwards along the radius direction of the sleeve body 1, and all water collecting holes 8 are formed in the lower portion of the water stop ring 7, so that the periphery of the sleeve body 1 is stopped, and water outside the sleeve body 1 enters the sleeve body 1 through the water collecting holes 8.

Furthermore, the sleeve body 1 is further coated with a filter screen, and the filter screen is coated on the periphery of the lower part of the water stop ring 7 to play a role in preventing sludge on the periphery of the sleeve body 1 from entering the sleeve body 1 through the water collecting holes 8. The filter screen can select a 10-mesh steel wire mesh and the like as required.

When precipitation is manually operated in the elevator shaft, a precipitation hole with the diameter of 600mm and the depth of 1.5m is drilled in the center of the base of each elevator shaft by a drilling machine, and silt in the hole is cleaned up. The steel sleeve pipe of diameter 400mm is then chooseed for use to sleeve body 1, and the lower pipe wall of sleeve body 1 bores the aperture of diameter 50mm and outsourcing 10 mesh wire net, and the fine gravel is backfilled around the pipe, and the sealing ring 7 sets up in the department of 400mm apart from sleeve body 1 bottom, and the width of sealing ring 7 sets up to 50 mm. And a self-sucking pump is adopted for dewatering, so that the underground water is lower than the substrate by 500 mm.

After precipitation is finished, before the floor of the elevator shaft is poured, the sealing gasket 4 or the sealing gasket 3 is placed according to the figure, the sleeve cover 2 is covered on the sealing gasket and fastened, and finally the bottom plate is poured.
