Description

Technical Field

[0001] The invention relates to the field of construction engineering, in particular to a composite anti-leakage method for a basement wall-mounted group pipe. Background Art

[0002] Under conventional construction techniques, due to the small gaps between pipes in the through-the-wall group pipe system, when pouring exterior wall concrete, the gaps between pipes can easily lead to loose concrete pouring, resulting in cracks or holes. At the same time, due to the complex shape of the out-of-wall group pipe system, it is difficult to perfectly fit the formwork when supporting it, resulting in an uneven concrete molding surface in the group pipe system, resulting in loose bonding with the waterproof layer, and creating a risk of leakage.

[0003] The solutions to the above problems include strengthening concrete vibration, strengthening quality control during construction, welding water steel plates on the group pipe system, and using multi-section steel plates for water stopping.

[0004] The above technology does not fundamentally solve the problem of loose concrete in the gaps between pipes, and cannot meet the long-term waterproof effect of the structure. There is still a great risk of leakage over time.

[0005] The existing technology only adds densifying ribs inside the wall to block water, which cannot guarantee the quality of the joints between the outer wall and the pipe group (because the distance between pipes in the pipe group system is usually small, and because concrete contains aggregates, it is difficult to fill the gaps between pipes during pouring), and cannot solve the current leakage risks. Summary of the invention

[0006] The present invention aims to overcome the defects of the prior art and provide a composite anti-leakage method for a basement wall group pipe, so as to solve the problem of water leakage in the wall group pipe.

[0007] In order to solve the above-mentioned technical problems, the present invention is achieved as follows: A composite anti-leakage method for a basement wall group pipe, characterized in that it comprises the following steps: Step 1: Prepare the built-in sealing ribs of the group pipe sealing waterproof device; Step 2: Weld the side panels and external sealing ribs of the group pipe sealed waterproof device; Step 3: Install the group pipe sealed waterproof device; Step 4: Grouting of the closed waterproof device of the group pipes; Step 5: Wall pouring; Step six: surface waterproofing construction.

[0008] The described method for composite anti-leakage of a basement wall group pipe is characterized in that: in step one, the size of the group pipe system uses 3-thick galvanized steel plates as built-in closed ribs, and the outer edge of the closed ribs exceeds the outer diameter of the external pipe; the group pipe system requires corresponding pipe holes to be opened on the closed ribs, and the hole openings are smoothed.

[0009] The described method for composite anti-leakage of a basement wall group pipe is characterized in that: in step 2, a galvanized steel plate of the same thickness as the built-in sealed rib is selected, and the side plate is welded to the encrypted rib by double-sided welding. The edge of the encrypted rib must extend beyond the side plate, and two × grouting holes are opened on the upper side plate; the external sealed rib is opened with corresponding pipe holes according to the design requirements of the group pipe system, and the external sealed rib is welded to the side plate after the pipe hole is smoothed.

[0010] The described method for composite anti-leakage of a basement wall group pipe is characterized in that: in step three, after the group pipe closed waterproof device is made, the device is installed on the outer wall formwork, and the wall pipe is inserted into the device at the same time, and then the outer wall of the wall pipe and the connection between the device are sealed by welding; the group pipe system points are compounded again to ensure that the points are consistent with the planned installation points.

[0011] The composite anti-leakage method for a group of pipes outside the basement wall is characterized in that: in step four, polymer waterproof mortar is used to perform grouting from a grouting hole on one side of a closed waterproof device, and a uniform speed is maintained during grouting. After filling, a vibrating rod is used to vibrate to ensure the density of the grouting.

[0012] The composite anti-leakage method for a basement wall group pipe is characterized in that: steps one to four make a group pipe sealing device to convert the contact surface between the group pipe system and the concrete wall into a flat and regular plane, and at the same time increase the rib density to enhance waterproofing.

[0013] The composite anti-leakage method for a basement wall group pipe is characterized in that: in step five, when the grouting liquid reaches the designed strength, concrete is poured on the wall, and during pouring, quality control is strengthened on the lower side of the group pipe system to avoid the formation of cavities.

[0014] The composite anti-leakage method for basement wall-mounted pipe groups is characterized in that: in step six, LEAC waterproof coating is used to perform waterproof reinforcement treatment on the joint between the surface layer of the wall-mounted pipe group system and the concrete wall.

[0015] The beneficial effects of the present invention are as follows: It can be seen from the above technical scheme that the present application provides a composite anti-leakage method for a basement wall group pipe, which changes the irregular, multi-curved contact surface between the group pipe and the wall into a flat, square plane, thereby improving the quality of the joints (the six sides of the group pipe sealing device are all flat, and during the concrete pouring process, they will have a good bonding effect with the concrete and will not form cavities), and combines the LEAC waterproofing process to strengthen the joints on the water-facing surface, thereby fundamentally solving the risk of leakage and increasing the service life of the waterproofing.

[0016] The present invention mainly solves the problem of easy leakage of the wall group pipe system from the following three aspects: 1. By injecting grout into the closed waterproof device of the group pipe, the gaps between the pipes in the group pipe system are ensured to be dense, thereby preventing moisture from penetrating into the wall, solving the problem that the gaps between pipes are too small to be poured densely when conventional concrete is poured.

[0017] 2. After installing the group-pipe closed waterproof device, the water-facing surface of the group-pipe system becomes a smooth plane, which is conducive to the later combination with the exterior wall waterproofing, thereby enhancing the overall waterproofing effect and solving the problem of the rough water-facing surface caused by the difficulty in supporting the formwork during conventional concrete pouring, thereby affecting the bonding effect with the exterior wall waterproofing.

[0018] 3. Use LEAC waterproof coating to strengthen the gap between the closed waterproof device of the group pipe and the wall, enhance the overall integrity and improve the waterproof effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments: Figure 1 This is a schematic diagram of step one; Figure 2 It is a schematic diagram of steps one to four; Figure 3 This is a schematic diagram of step five. DETAILED DESCRIPTION

[0020] The technical solutions of the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments in the embodiments of the present application are within the scope of protection requested by the present application. like Figure 1-3 As shown: A composite anti-leakage method for a basement wall group pipe, which includes the following steps: Step 1: Prepare the internal sealing ribs of the group pipe sealed waterproof device Through test comparison, the size of the group pipe system uses 3-thick galvanized steel plates as built-in sealing ribs, and the outer edge of the sealing ribs exceeds the outer diameter of the external pipe.

[0021] Special note: The group pipe system requires that corresponding pipe holes be opened on the closed ribs and the hole openings be smoothed. The size of the pipe holes is determined according to the actual size of the pipeline.

[0022] Step 2: Weld the side panels and external sealing ribs of the group pipe sealed waterproof device. After comparison, galvanized steel plates of the same thickness as the internal closed ribs were selected, and the side panels were welded to the encrypted ribs by double-sided welding. The edges of the encrypted ribs should extend beyond the side panels, and two × grouting holes were opened on the upper side panels. The external closed ribs were opened with corresponding pipe holes according to the design requirements of the group pipe system, and the external closed ribs were welded to the side panels after the pipe holes were smoothed.

[0023] Step 3: Install the group pipe sealed waterproof device After making the group pipe sealed waterproof device, install the device on the exterior wall formwork, insert the wall pipe into the device, and then seal the connection between the outer wall of the wall pipe and the device by welding; compound the group pipe system points again to ensure that the points are consistent with the planned installation points.

[0024] Step 4: Grouting of the closed waterproof device of the group pipe Use polymer waterproof mortar to inject grout from the injection hole on one side of the closed waterproof device, and keep the speed uniform during injection. After filling, use a vibrating rod to vibrate to ensure the density of the grouting.

[0025] Special note: Steps 1 to 4 are mainly to make the contact surface between the group pipe system and the concrete wall into a flat, regular plane by making a group pipe sealing device, rather than the multi-curved joints formed between the pipe wall and the concrete in the conventional practice. This can greatly improve the joint quality between the concrete wall and the group pipe system and reduce the risk of leakage. At the same time, the design of the dense ribs can enhance the waterproof effect and play a positive role in the century-old waterproof design requirements of the building.

[0026] Step 5: Wall pouring When the grouting liquid reaches the designed strength, concrete is poured on the wall. During pouring, quality control is strengthened on the lower side of the group pipe system to avoid cavities.

[0027] Step 6: Surface waterproofing construction LEAC waterproof coating is used to strengthen the waterproofing of the joints between the surface layer of the wall group pipe system and the concrete wall.

[0028] Step 6: By using the LEAC waterproofing process, the waterproofing at the joint between the group pipe sealing device and the concrete wall is strengthened, which can perfectly fit the joint position between the device and the concrete wall and achieve a good waterproofing reinforcement effect.

[0029] Through the combination of LEAC waterproofing technology and group pipe sealing device, a composite anti-leakage method of basement wall group pipes is formed, which greatly improves the waterproofing effect of the project's exterior wall and meets the design requirements of a hundred-year waterproofing.

[0030] The above are only embodiments provided for the present application and are not intended to limit the present application. Although the present application is described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
