Description

Technical Field

[0001] The utility model relates to the technical field of civil construction installation, in particular to a temporary plugging device for a waterproof casing. Background Art

[0002] Since there are a large number of reserved water supply and drainage casings on the basement exterior wall, if they are not temporarily blocked before the total earthwork is backfilled, rainwater, mud and other impurities will seep into the basement through the waterproof casing openings, causing pollution to the ground or walls, affecting indoor operations and the protection of finished products, and increasing indoor operation safety risks and construction costs. In view of the particularity of basement exterior wall construction, the reserved casing must be a waterproof casing to prevent groundwater from seeping into the basement.

[0003] The existing installation process of plugging the reserved casing on the outer wall of the basement is: cutting and processing the waterproof casing → pre-embedded installation of the waterproof casing → plugging the pipe opening of the waterproof casing. At present, asbestos wool or plugging agents are used to plug the waterproof casing at the construction site. This method has the problems of high labor intensity, difficult quality control, poor working environment, low labor efficiency, and large material waste, which are specifically manifested as follows:

[0004] 1. The construction steps of outdoor waterproof casing pipe opening plugging are complicated. The existing practice is to directly use asbestos cement, plugging agent, etc. for temporary plugging. The plugging effect of outdoor pipe opening is often not good. In the later stage, it is easy for outdoor pipe opening to seep into the indoor basement, causing large-scale water accumulation in the basement, which is easy to form a construction operation hazard source, pollute the wall or ground, and thus damage the finished product;

[0005] 2. In the later stage of secondary construction of outdoor casing, mechanical tools are used to open the temporary plugging. However, it is very difficult to remove the temporary plugging materials before the operation. Operators usually use methods such as knocking and shaking the casing to forcefully remove the plugging materials. The casing is easily damaged during the process, causing the casing mouth to need secondary repair treatment, which increases labor and material costs, making it difficult to control the quality of finished products and process costs;

[0006] 3. Due to the large number of drainage sleeves reserved for the basement outer wall and their wide distribution, a large amount of asbestos cement, plugging agents and other materials will be consumed for plugging during the entire construction process, and a large amount of labor will also be consumed accordingly. During the temporary plugging construction process, due to the characteristics of the plugging materials, residual toxic and harmful materials will be generated at the construction site, which is difficult to clean up, thereby polluting the soil and not meeting relevant requirements such as green environmental protection. Utility Model Content

[0007] Based on the problems pointed out in the background technology that the existing waterproof casing sealing method has poor sealing effect and difficulty in removing the sealing material, the purpose of this application is to propose a temporary sealing device for a waterproof casing, which can achieve accurate positioning and precise installation of the pipe mouth and high construction quality, thereby reducing the risk of water seepage in the waterproof casing in the later stage and having good sealing effect. At the same time, the sealing device is also easy to disassemble without causing damage to the sealing pipe, and can also achieve the recycling of the sealing device.

[0008] The utility model is realized by the following technical solutions:

[0009] The present application provides a temporary sealing device for a waterproof casing, comprising a tension rod, wherein both ends of the tension rod are respectively connected to an internal wall fixing structure and an external wall sealing structure; the internal wall fixing structure comprises a fixing rod, wherein the fixing rod is connected to the tension rod, and the length of the fixing rod is greater than the inner diameter of the waterproof casing; the external wall sealing structure comprises a blind plate, wherein the blind plate is fixed to the tension rod by a locking structure.

[0010] The blind plate comprises a circular blind plate, and the outer diameter of the circular blind plate is greater than the inner diameter of the waterproof casing.

[0011] Furthermore, the fixed rod is connected to the tension rod through a rotating component 1; the rotating component 1 includes a through hole arranged on the fixed rod, a rotating shaft is installed in the through hole, the fixed rod is connected to the rotating shaft, the tension rod is connected to a connecting piece, and the connecting piece is connected to the fixed rod through the rotating shaft.

[0012] The tension rod and the connecting piece may be fixed by welding or by other detachable connecting pieces.

[0013] Furthermore, the fixing rod is connected with an adjustment structure.

[0014] Furthermore, the adjustment structure includes a push rod connected to the fixing rod.

[0015] The adjusting structure is used to push the push rod outward when disassembling the blocking device, so that the fixing rod is rotated to be parallel to the waterproof sleeve, so as to facilitate taking it out of the waterproof sleeve.

[0016] In the case where the adjusting structure is not installed, when the staff dismantles the blocking device, they need to remove the blind plate on the outside of the wall and then enter the inside of the wall to remove the fixed structure inside the wall, which is very inconvenient during the removal process.

[0017] By connecting the adjustment structure, when the staff is dismantling, after removing the blind plate, the staff can hold the push rod and push it outward to rotate the fixing rod to be almost parallel to the inner cavity of the waterproof casing, and then directly pull out the fixed structure in the wall. There is no need for the staff to guide the inside of the wall to dismantle it, which makes it more convenient for the staff to dismantle and thus improves work efficiency.

[0018] Furthermore, a rotating assembly 2 is connected between the push rod and the fixed rod, and the structure of the rotating assembly 2 is the same as that of the rotating assembly 1.

[0019] Furthermore, the locking structure includes a threaded groove arranged on the tension rod, and the blind plate is fixed by screwing a locking nut on the tension rod.

[0020] Among them, a section of thread groove can be arranged at the end of the tension rod, and the thread groove can also be arranged on the entire tension rod, that is, the tension rod adopts a screw rod.

[0021] By setting a threaded groove on the tension rod, after the tension rod passes through the blind plate, the blind plate can be fixed by directly installing a locking nut on the tension rod. The installation and disassembly are very simple, and the sealing effect is good and the positioning is accurate. The waterproof casing will not be damaged during disassembly.

[0022] In addition, when the tension rod is set as a screw rod, the blocking device can be applied to waterproof casings of different lengths, thereby expanding the application scope of the blocking device.

[0023] Furthermore, a rubber pad and a metal gasket are installed between the locking nut and the blind plate. The installed rubber pad can block the gap between the tension rod and the hole where the tension rod is installed. The installed metal gasket can increase the contact area between the nut and the connected part, thereby dispersing the pressure and reducing the damage of the rubber pad and the nut caused by excessive local pressure. Among them, the metal gasket is connected to the nut.

[0024] Furthermore, the blind plate is provided with a groove, and the waterproof sleeve is installed in the groove of the blind plate.

[0025] By arranging a groove on the blind plate, the waterproof sleeve can be inserted into the groove, compared with a flat blind plate, which can prevent water from penetrating from the gap where the blind plate and the waterproof sleeve contact.

[0026] Furthermore, a sealing structure is installed in the groove of the blind plate.

[0027] Furthermore, the sealing structure includes a sealing ring connected to the side wall of the groove, and when the waterproof sleeve is inserted into the groove, the sealing ring contacts and seals against the outer wall of the waterproof sleeve.

[0028] By further connecting a sealing ring to the side wall of the groove of the blind plate and utilizing the elasticity of the sealing ring, a contact seal is formed between the outer wall of the waterproof casing and the sealing ring, thereby further enhancing the sealing performance of the blind plate.

[0029] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0030] (1) The plugging device in the present application can achieve accurate positioning and precise installation of the pipe orifice plugging, improve the construction quality, reduce the risk of casing water seepage in the later stage, and have a good plugging effect. In addition, the plugging device is easy to disassemble and recycled, while reducing the use of traditional plugging materials, improving economic benefits, and reducing construction pollution in the construction process, meeting the requirements of green environmental protection;

[0031] (2) The present application connects the inner wall fixing structure and the outer wall sealing structure at both ends of the tension rod respectively, so that the two ends of the tension rod are pressed tightly, thereby preventing the displacement of the sealing device and achieving a good sealing effect of the pipe opening of the waterproof casing. At the same time, the sealing device has good adjustability and installation adaptability, thereby improving the construction efficiency. The disassembly and installation of the sealing device are very convenient, and the sealing device can be recycled, thereby improving the economic benefits of the project.

[0032] (3) The adjustment structure of the present application allows the staff to remove the blind plate and then push the push rod outward to rotate the fixing rod to be nearly parallel to the inner cavity of the waterproof casing, thereby directly pulling out the fixing structure inside the wall. The staff does not need to disassemble the structure by guiding the staff inside the wall, which makes it more convenient for the staff to disassemble the structure, thereby improving work efficiency.

[0033] (4) By providing a groove on the blind plate, the present application allows the waterproof sleeve to be inserted into the groove, compared with a flat blind plate, thus preventing water from seeping in from the gap at the contact point between the blind plate and the waterproof sleeve;

[0034] (5) The present application further connects a sealing ring to the side wall of the groove of the blind plate and utilizes the elasticity of the sealing ring to form a contact seal between the outer wall of the waterproof sleeve and the sealing ring, thereby further enhancing the sealing performance of the blind plate.
