Description

Technical Field

[0001] This application belongs to the technical field of casing plugging, and specifically relates to a waterproof casing plugging device. Background Art

[0002] The main function of the waterproof casing is to prevent water seepage, flow, and dripping to the lower floor below. However, some construction units use incorrect methods to block the installation of waterproof casings, especially the problem of blocking waterproof casings, resulting in poor later use effects. In this regard, if not handled properly, it is easy to cause leakage and quality problems. Therefore, plugging the waterproof casing is very important.

[0003] In actual construction, after the construction of the flexible waterproof casing by the construction unit is completed, if the relevant pipeline unit does not carry out construction, there is a risk of leakage and dirt on the waterproof casing. It may cause pollution to the interior of the building. Therefore, how to temporarily plug the flexible waterproof casing is an unavoidable problem. Therefore, for the temporary structural plugging of the casing, the concept of a new type of flexible waterproof casing plugging device has been proposed. Utility Model Content

[0004] The purpose of this application is to provide a waterproof casing plugging device to solve the problem mentioned above that after the construction of the flexible waterproof casing is completed, if the relevant pipeline unit does not carry out construction, there is a risk of leakage and dirt on the waterproof casing, which may cause pollution to the interior of the building.

[0005] The technical solution adopted in this application is as follows: It includes a shaped steel plate, a connection seat is fixedly installed inside the shaped steel plate, a positioning groove is fixedly installed inside the connection seat, a water-swellable waterproof strip is fitted on the outer surface of the positioning groove, a threaded column is fixedly installed at the other end of the positioning groove, and a fixed screw cap is threadedly installed on the outer surface of the threaded column.

[0006] By adopting the above technical solution, a connecting seat is fixedly installed on the inner side of the shaped steel plate. A positioning groove is fixedly installed on the inner side of the connecting seat. A water-swelling waterproof strip is fitted on the outer surface of the positioning groove. A threaded post is fixedly installed at the other end of the positioning groove. A fixing cap is threadedly installed on the outer surface of the threaded post. The shaped steel plate serves as the installation foundation of the plugging device, and its material is Q235B steel plate. And an anti-corrosion paint is applied on the outer surface of the shaped steel plate, so as to do a good job in the anti-corrosion measures of the shaped steel plate. The connecting seat is used to bring the plugging component into the pipeline component to plug it. If the relevant pipeline unit does not carry out construction, the connecting seat can be used for temporary plugging to prevent the site from being polluted. The positioning groove is an annular groove embedded in the inner part of the connecting seat. The positioning groove can provide a placement position for the water-swelling waterproof strip to be fitted between the shaped steel plate and the connecting seat. The water-swelling waterproof strip can rapidly expand when it comes into contact with moisture, forming a sealed barrier to prevent moisture from penetrating into the pipeline through the gaps. The combination of the threaded post and the fixing cap is adopted. The threaded post is used to provide conditions for the installation of the fixing cap. By disassembling and assembling the fixing cap, it is convenient for the staff to replace the water-swelling waterproof strip. First, screwing the fixing cap into the inner part of the threaded post can fix the water-swelling waterproof strip inside the positioning groove and prevent it from shifting. On the contrary, loosening the fixing cap from the inner part of the threaded post can take out the water-swelling waterproof strip from the outer surface of the positioning groove, thus facilitating the staff to replace the used water-swelling waterproof strip. By setting this device on the outer surface of the casing, it can solve the problems that after the construction of the flexible waterproof casing is completed, if the relevant pipeline unit does not carry out construction, there are risks of leakage and dirt in the waterproof casing, and avoid polluting the interior of the building.

The flange is used to provide installation conditions for the docking between the device and the pipeline.

[0009] In a preferred embodiment, a wall is fixedly installed on the outer surface of the flexible casing.

[0010] By adopting the above technical solution, a wall is fixedly installed on the outer surface of the flexible casing. The wall provides the conditions for the flange to pass through and be fixed, so that the flexible casing can pass through the building structure stably without displacement.

[0012] By adopting the above technical solution, a flange gasket is fitted and installed between the shaped steel plate and the flange.
