[0025] Reference Figure 1-4 As shown, it is a preferred embodiment provided by the utility model.
[0026] A drainage well sealing structure with a water-stop wing ring comprises a foundation pit 1, a drainage well 2 is opened in the foundation pit 1, a well pipe 3 is installed at the bottom of the drainage well 2, a steel sleeve 4 is connected to the top of the well pipe 3, a blind plate 5 is movably installed at the top of the steel sleeve 4, a concrete structural plate 6 is cast in the foundation pit 1, the steel sleeve 4 is cast in the concrete structural plate 6, an annular water-stop wing ring 10 is installed at the outer edge of the steel sleeve 4, and the distance from the water-stop wing ring 10 to the bottom of the concrete structural plate 6 is greater than 15 cm.
[0027] When the sealing structure is used, the well pipe 3 and the steel casing 4 are first welded into a whole, which is placed in the precipitation well 2, and then the blind plate 5 is movably installed on the steel sleeve 4, and then the concrete structural plate 6 is poured into the foundation pit 1. The structure places the well pipe 3 and the steel sleeve 4 into the precipitation well 2 so that the soil around the precipitation well 2 can be effectively restricted outside the well pipe 3, thereby ensuring that the precipitation well 2 will not be eroded by the soil so that the precipitation function of the precipitation well 2 is affected; by pouring the concrete structural plate 6 in the foundation pit 1, the well pipe 3 and the steel sleeve 4 can be effectively confined to a specific position, and at the same time have a good waterproof effect, and effectively improve the anti-leakage effect of water leakage around the precipitation well 2.
[0028] Specifically, in this embodiment, a plurality of filter holes are evenly distributed on the well pipe 3, and the sizes of the plurality of filter holes are all smaller than the size of the gravel.
[0029] By setting filter holes on the well pipe 3, water outside the well pipe 3 can flow into the precipitation well 2, while mud and sand are blocked by the well pipe 3 and cannot enter the precipitation well 2, thereby ensuring the storage volume in the precipitation well 2.
[0030] Specifically, in this embodiment, the well pipe 3 and the steel sleeve 4 are both made of high-strength metal materials.
[0031] Since the well pipe 3 and the steel sleeve 4 are made of metal materials, they can withstand the pressure exerted by the soil around the precipitation well 2 on the well pipe 3 and the steel sleeve 4, thereby ensuring the normal use of the well pipe 3 and the steel sleeve 4.
[0032] Specifically, in this embodiment, the well pipe 3 and the steel sleeve 4 are connected by welding.
[0033] Installing the well pipe 3 and the steel sleeve 4 together by welding can make the connection between the well pipe 3 and the steel sleeve 4 more secure, thereby avoiding the separation of the well pipe 3 and the steel sleeve 4.
[0034] Specifically, in this embodiment, a flange 7 is installed on the top of the steel sleeve 4, and the flange 7 is prefabricated on the steel sleeve 4 before construction.
[0035] The provision of the flange 7 can increase the cross-sectional area of the top end of the steel sleeve 4 , thereby facilitating the connection between the steel sleeve 4 and the blind plate 5 .
[0036] Specifically, in this embodiment, a rubber pad 8 is provided between the flange 7 and the blind plate 5 , and the rubber pad 8 , the blind plate 5 and the flange 7 have the same size.
[0037] The provision of the rubber pad 8 can make the connection between the blind plate 5 and the steel casing 7 tighter, thereby achieving a waterproof and sealing effect.
[0038] Specifically, in this embodiment, the distance between the blind plate 5 and the top of the concrete structure plate 6 is greater than 15 cm.
[0039] Since the distance between the blind plate 5 and the top of the concrete structure plate 6 is greater than 15 cm, the blind plate 5 can maintain an appropriate distance from the top of the concrete structure plate 6, thereby preventing water leakage.
[0040] Specifically, in this embodiment, a skirt 9 is installed on the outer curved surface of the blind plate 5 , and the inner curved surface of the skirt 9 is matched with the outer curved surface of the flange 7 in size.
[0041] The skirt 9 is provided so that the blind plate 5 can be sleeved on the flange 7, thereby facilitating quick installation of the blind plate 5 and improving work efficiency.
[0042] Specifically, in this embodiment, a plurality of connection blocks 11 are elastically connected inside the skirt 9 , and the plurality of connection blocks 11 can be exposed outside the skirt 9 . A plurality of connection grooves 12 are provided on the flange 7 , and the plurality of connection blocks 11 are slidably fitted into the connection grooves 12 .
[0043] By setting the connecting block 11 and the connecting groove 12, the blind plate 5 connected to the skirt 9 can be installed on the flange 7 through the connecting block 11. This method is simple to operate and has high installation efficiency.
[0044] Specifically, in this embodiment, an end of a plurality of connection blocks 11 close to the steel sleeve 4 is provided with an inclined surface.
[0045] By setting the inclined surface, when the connecting block 11 contacts the top of the flange 7, the flange 7 can push the connecting block 11 into the skirt 9 through the setting of the inclined surface, so that the skirt 9 can be sleeved on the flange 7 without obstacles.
[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
