Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and specifically relates to a water blocking device for a wall-penetrating pipe and a water blocking construction structure. Background Art

[0002] In underground projects, many spare wire threading pipes are often reserved on the wall. Since these wire threading pipes need to penetrate the wall, they are also called wall-penetrating pipes. In order to prevent water from penetrating these wall-penetrating pipes, these wall-penetrating pipes are usually sealed with cement or mastic materials. The problems are: 1) The quality of the sealing depends on the construction techniques and responsibility of the operators. Therefore, when the construction techniques are not appropriate or the operation is sloppy and not serious, the sealing is often not tight and there are leakage points; 2) The mastic sealing materials often shrink after curing, and the shrinkage of the mastic often causes the mastic and the leakage to be caused by the shrinkage of the mastic. Gaps appear at the joints of the pipes, causing water leakage, and cement materials will form cracks after solidification, which will also cause water leakage; 3) The plugging materials used in this sealing method are glued to the inner wall of the pipe, and their ability to resist water pressure is poor. When the groundwater level rises, the water pressure is usually large. At this time, the plugging materials are easily washed away; 4) When the through-wall pipe needs to be put into use, these plugging materials need to be cleaned out, and these plugging materials are solidified on the inner wall of the production line pipe and are difficult to clean; 5) The plugging materials can only be used once and cannot be reused.

[0003] To solve the above problems, the utility model patent with application number 202022059219.2 discloses a wall-penetrating pipe sealing structure, which is provided with two inner and outer sealing parts, and the two sealing parts are connected by a connecting piece. When in use, the sealing structure needs to pass through the entire wire threading pipe. Therefore, it is only suitable for shorter wire threading straight pipes that penetrate the wall, but cannot be used for sealing wall-penetrating curved pipes or long wall pipes. Wire threading pipes of different lengths require sealing structures of different sizes and models, and the sealing structure has poor versatility. In addition, when installing it, two people are required to operate on the inside and outside of the wall respectively, which is time-consuming, labor-intensive and labor-intensive. Utility Model Content

[0004] The utility model aims to overcome a series of defects caused by the use of mastic or cement sealing for wall-penetrating pipelines in the prior art, and provides a wall-penetrating pipe water blocking device and a water blocking construction structure.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A wall-penetrating pipe water blocking device comprises a fixed plate, a movable plate, an elastic sealing member arranged between the fixed plate and the movable plate, and a driving device for driving the movable plate to move away from or close to the fixed plate.

[0007] As a further technical solution, the driving device includes a first through hole on the fixed plate, a second through hole on the elastic seal, and an adjusting bolt passing through the first through hole and the second through hole, and the adjusting bolt is connected to the movable plate by threads.

[0008] As a further technical solution, a washer is provided between the bolt cap of the adjusting bolt and the fixing plate.

[0009] As a further technical solution, the fixed plate and the movable plate are provided with anti-slip textures on one side close to the elastic seal;

[0010] The outer wall of the elastic sealing member is provided with a plurality of annular convex textures.

When in use, the fixed plate is fixed to the wall, the movable plate and the elastic sealing member are inserted into the threading tube, and the movable plate is slid by the driving device, so that the elastic sealing member is squeezed and expanded, thereby achieving sealing between the elastic sealing member and the inner wall of the pipe.
