Description

Technical Field

[0001] This invention belongs to the field of leakage repair technology, and in particular relates to a wall-penetrating pipe sealing device. Background Technology

[0002] Piped water supply is widely used in society. As water pipes age, cracks or openings sometimes appear, especially at wall penetrations where leaks are more prominent. As urban water supply pipelines, they must be repaired as soon as possible. Current technology for sealing pipe leaks typically involves first shutting off the water supply, then excavating the leak location. Once the leak point is located, a pit is created within a radius of several meters, and flour is poured into the pit to form a cofferdam, ensuring that workers can effectively seal the leak. However, due to the long distances of water supply pipelines, shutting off the entire pipeline is difficult, and constructing the cofferdam before sealing is not only complex but also consumes a large amount of flour, resulting in time-consuming and costly pipe sealing operations. Therefore, it is necessary to improve existing pipe penetration sealing equipment. Summary of the Invention

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] A wall-penetrating pipe sealing device, such as Figures 1 to 5 As shown, the system includes a functional cover 1 located at the end of the working pipe 14. An operating port 2 is provided at the lower part of the functional cover, and a control valve 3 is installed at the operating port. In an optional embodiment, the operating port includes a cylindrical tube 8 corresponding to a water passage hole at the lower part of the functional cover. The upper end of the cylindrical tube is welded and fixed to the functional cover, allowing communication between the cylindrical tube and the enclosed space inside the functional cover. A connecting flange 10 is provided at the lower end of the cylindrical tube, and the control valve is installed on the connecting flange. For example, the control valve is a gate valve. During the sealing operation, the leaking water flows out through the cylindrical tube. After the functional cover is welded closed, the control valve on the cylindrical tube is closed, thus completing the pipe sealing. The operation is simple and easy to implement.

[0029] A liquid storage chamber 4 is formed between the functional cover and the inner sleeve 9, and the liquid storage chamber is connected to the operating port; the functional cover includes an arc-shaped sealing plate 5, each end of the upper part of the sealing plate is provided with a top plate 6 between it and the inner sleeve, and the end of the sealing plate away from the working pipe is provided with an end plate 7, and the gap between the sealing plate and the inner sleeve gradually increases from the side closer to the working pipe to the side farther away from the working pipe, that is, the arc of the sealing plate gradually increases from the side closer to the working pipe to the side farther away from the working pipe.

[0030] The sealing plate is welded and fixed to the top plate, and the end plate is welded and fixed to the sealing plate. The sealing plate is welded and fixed to the end of the working pipe. The top plate is welded and fixed to the inner sleeve. The end plate is annular, with its inner side welded and fixed to the inner sleeve and its outer side welded and fixed to the functional cover. For example, the thickness of the sealing plate, top plate, and end plate is 10mm.

[0031] The construction method for the above-mentioned through-wall pipe sealing device includes the following steps:

[0032] 1. First, a slope 12 is chiseled on the surface of the wall 11 corresponding to the outer perimeter of the working pipe; usually, the slope is 45 degrees, for example, the slope is 30mm x 30mm.

[0033] 2. Weld a sealing plate to the end of the working pipe, then weld an end plate to the end of the sealing plate, and then weld the end plate to the inner sleeve for fixation;

[0034] 3. Weld a top plate between the upper part of the sealing plate and the inner sleeve to form a liquid storage cavity between the functional cover and the inner sleeve;

[0035] 4. During the above steps, any water leaking from the wall will drain through the operating port, ensuring the successful welding of the functional cover. Finally, closing the control valve completes the pipe sealing operation. To prevent accidental operation of the control valve, it can be welded shut after closing.

[0036] like Figure 6 As shown, when welding the sealing plate to the working pipe, first use the water-stop strip 13 to plug the gap between the sealing plate and the inner sleeve corresponding to the welding position, and then perform welding to avoid water leakage affecting the welding quality at the welding position. In the case of large leakage, the operation method can be adopted to use the water-stop strip to seal only the welding position as the welding position changes, to avoid water overflow at the welding position and affecting the welding quality.

[0037] like Figure 7 As shown, when welding the end plate to the sealing plate, the waterstop strip can be pressed against the welding position between the end plate and the sealing plate using an iron wire or steel rod. Then, the sealing position of the waterstop strip is welded. During the welding process, the sealing position of the waterstop strip is adjusted adaptively as the welding position changes to avoid water overflowing from the welding position and affecting the welding quality.

[0038] like Figure 8 As shown, when welding the end plate to the inner sleeve, the waterstop strip can be pressed against the welding position between the end plate and the inner sleeve using an iron wire or steel rod. Then, the sealing position of the waterstop strip is welded. During the welding process, the sealing position of the waterstop strip is adjusted adaptively as the welding position changes, thereby avoiding water overflow at the welding position and affecting the welding quality.

[0039] The wall-penetrating pipe sealing device provided by this invention has a simple structure and reasonable design. By welding a functional cover to the end of the working pipe, a closed space is formed inside the functional cover. When welding this wall-penetrating pipe sealing device, leaked water is allowed to flow out through the operating port. After the sealing device is welded, the operating port is closed by controlling the valve to complete the wall-penetrating pipe sealing. The construction operation is simple, time-saving and labor-saving.

[0040] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
