[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0024] In the construction of pipelines penetrating walls, quality problems such as water seepage, pipeline damage, and inadequate sealing often occur. This is especially true for pipelines penetrating external walls under the influence of groundwater. Groundwater pressure, soil settlement, and vibrations and displacement caused by pipeline installation can lead to inadequate sealing of the casings, posing a risk of leakage and failing to effectively guarantee the overall waterproofing performance of the building. Therefore, solving these problems, ensuring the safety and stability of the project, improving the sealing and seepage prevention performance of various pipelines penetrating building walls, guaranteeing the structural safety of buildings and the efficient and safe use of building equipment, and meeting people's needs for automated, intelligent, and electrified building functions are urgent challenges that need to be addressed. (See also...) Figure 1-7 The present invention provides a novel through-wall anti-seepage sleeve device, including a through-wall sleeve 1, a flange 2, a sealing ring 3, a pressure ring 4, a bolt 5, and a wing ring 6.
[0025] The through-wall sleeve 1 extends horizontally. Its length is greater than the thickness of the wall 10 but less than the length of the through-wall pipeline 9. The inner diameter of the through-wall sleeve 1 is greater than the outer diameter of the through-wall pipeline 9, allowing the through-wall sleeve 1 to penetrate the wall 10 and the through-wall pipeline 9 to penetrate the through-wall sleeve 1. There is a gap between the outer circumferential wall of the through-wall pipeline 9 and the inner circumferential wall of the through-wall sleeve 1. The through-wall sleeve 1 can be made of cast iron, ductile iron, or stainless steel, depending on the application environment. The outer diameter of the through-wall sleeve 1 can be no less than 1.5 times that of the through-wall pipeline 9.
[0026] The through-wall sleeve 1 has a grouting hole and an overflow hole at both ends, respectively. The grouting hole and the overflow hole are located at the lower and upper parts of the through-wall sleeve 1, respectively. The distance between the grouting hole and the overflow hole is greater than the thickness of the wall 10, so that both the grouting hole and the overflow hole are located outside the wall 10. Sealing grout is injected into the through-wall sleeve 1 through the grouting hole. After filling, the sealing grout flows out of the through-wall sleeve 1 through the overflow hole. The grouting hole has a grouting connector 7. A removable first plug is installed at the end of the grouting connector 7. The overflow hole has an overflow connector 8. A removable second plug is installed at the end of the overflow connector 8.
[0027] Flange 2 has a ring-shaped structure. The inner diameter of flange 2 is equal to the inner diameter of through-wall sleeve 1, and the outer diameter is larger than the outer diameter of through-wall sleeve 1. Flange 2 is coaxially mounted at both ends of through-wall sleeve 1. Flange 2 has multiple first mounting holes 201, the axis of each first mounting hole 201 being parallel to the axis of through-wall sleeve 1. The first mounting holes 201 are evenly arranged around the axis of flange 2, and each first mounting hole 201 is for bolts 5 to pass through. Flange 2 can be fully welded around the circumference of through-wall sleeve 1 using fillet welds.
[0028] The inner diameter of the sealing ring 3 is less than or equal to the outer diameter of the through-wall pipe 9, and the outer diameter is equal to the outer diameter of the through-wall sleeve 1 or the outer diameter of the flange 2. The sealing ring 3 is coaxially mounted on the side of the flange 2 away from the mounting sleeve. The sealing ring 3 is disposed to avoid contact with each of the first mounting holes 201, or the sealing ring has multiple through holes 301, each of which corresponds to each of the first mounting holes 201, and each through hole 301 is for bolts 5 to pass through. The inner diameter of the sealing ring 3 can be slightly smaller than the inner diameter of the through-wall sleeve 1 by 0.5mm to 1mm. The sealing ring 3 is made of rubber.
[0029] The inner diameter of the pressure ring 4 is equal to the inner diameter of the flange 2, and the outer diameter is equal to the outer diameter of the flange 2. The pressure ring 4 is coaxially disposed on the side of the sealing ring 3 away from the flange 2, and presses the sealing ring 3 onto the flange 2. The pressure ring 4 has multiple second mounting holes, each corresponding to a first mounting hole 201, and each second mounting hole is for bolts 5 to pass through.
[0030] Bolt 5 connects the pressure ring 4 to the flange 2. There are multiple bolts 5, each with a thread that passes through the corresponding first mounting hole 201.
[0031] The inner diameter of the wing ring 6 is equal to the inner diameter of the through-wall sleeve 1, and the outer diameter is equal to the outer diameter of the flange 2. The wing ring 6 is coaxially mounted on the outer peripheral wall of the through-wall sleeve 1 and is located in the middle of the through-wall sleeve 1. The wing ring 6 can be welded along the body of the through-wall sleeve 1 using double-sided fillet welds. The width of the wing ring 6 is designed and cut according to the dimensions specified in the national standard drawing 02S404.
[0032] The novel through-wall seepage prevention sleeve device may also include a sleeve 10. The sleeve 10 is coaxially fitted inside the through-wall sleeve 1. The outer diameter of the sleeve 10 is equal to the inner diameter of the through-wall sleeve 1, and the inner diameter of the sleeve 10 is greater than the outer diameter of the through-wall pipeline 9. The axial length of the sleeve 10 is equal to the sum of the axial length of the through-wall sleeve 1 and the axial thickness of the flange 2. The sleeve 10 has a first opening and a second opening, which are respectively connected to a grouting hole and an overflow hole, allowing sealing grout to be injected into the sleeve 10 from the grouting hole and the first opening. After filling, the sealing grout flows out of the through-wall sleeve 1 from the second opening and the overflow hole. Under these conditions, during subsequent maintenance, the sleeve 10 is pushed out of the through-wall sleeve 1, cut, and the sealing grout inside the sleeve 10 is removed, allowing the through-wall pipeline 9 to be extracted.
[0033] It should be noted that the wall sleeve 1 should be grouted and sealed according to the on-site water environment conditions, site conditions and equipment seepage prevention requirements. After the device is manufactured, it should be calibrated and tested for impermeability. Only after passing the test can the anti-corrosion and painting processes of the device be carried out.
[0034] This novel through-wall anti-seepage sleeve device can prevent groundwater or surface water from seeping into the sleeve or the interior of the building, thereby protecting the safety and stability of underground through-wall pipelines 9 and ensuring the waterproof performance of the building. This novel through-wall anti-seepage sleeve device ensures safe and efficient pipeline through-wall construction, meets quality requirements, effectively improves construction efficiency, is easy to install and maintain, and has simple material sourcing and manufacturing process, making it economical and reasonable, and suitable for widespread use.
[0035] The installation and use process of this novel through-wall seepage prevention sleeve device is as follows:
[0036] First, design and draw the processing drawings of the new wall-penetrating anti-seepage sleeve device according to the type and size of the wall-penetrating pipeline 9, and then complete the fabrication of the new wall-penetrating anti-seepage sleeve device.
[0037] After the reinforcement of wall 10 is tied, the through-wall sleeve 1 with flange 2 is laid out and positioned; then, the through-wall sleeve 1 is installed and fixed according to the pre-embedded position; next, the formwork at both ends of the through-wall sleeve 1 is installed and sealed to prevent grout leakage; then, the concealed works acceptance work before the construction of wall 10 is carried out, paying attention to checking the plane position, elevation and specifications of the through-wall sleeve 1 for verification and timely adjustment; when pouring structural concrete, special attention should be paid to the vibration of the concrete at the through-wall sleeve 1 to ensure compaction and reliability; wait for the wall to be completed. 10. After the structure reaches its service life, remove the formwork. Conduct a water spray test on the exterior wall surface at the through-wall sleeve 1 to ensure that the exterior wall structure does not leak. Then, carry out detailed waterproofing work around the through-wall sleeve 1 (laying rolled material or applying waterproof coating). The pipeline is sequentially inserted into the inner pressure ring 4 of the wall 10, the inner sealing ring 3 of the wall 10, the through-wall sleeve 1, the outer sealing ring 3 of the wall 10, and the outer pressure ring 4 of the wall 10. Next, install the sealing ring 3 and the pressure ring 4, and tighten the bolts 5 to complete the installation of the new through-wall anti-seepage sleeve device. (If necessary) The type of sealing grout can be selected according to the usage, and pressure grouting can be performed for sealing, sealing effect verification, and secondary grouting.
[0038] The novel through-wall seepage-proof sleeve device of this utility model has the following effects:
[0039] 1. Traditional wall sleeve construction often requires sealing the gap between the sleeve and the pipeline after the pipeline passes through the wall. This construction method makes it difficult to guarantee the sealing quality and the uniformity of the sealing material, which can lead to the infiltration of outdoor groundwater or rainwater into the sleeve and the interior of the building, affecting the waterproof performance of the building. This utility model can avoid the above-mentioned quality problems by adding sealing rings 3 to both ends of the wall sleeve 1.
[0040] 2. In traditional construction, there are no sealing measures at both ends of the wall sleeve. Small objects such as rats and ants can enter the pipe and damage the pipeline, causing communication and power outages and equipment failures. This utility model can effectively prevent the above situations from occurring by adding sealing rings 3 to both ends of the wall sleeve 1.
[0041] 3. In the process of traditional conduit passing through walls, pipelines are easily damaged when passing through walls, floors and other structures, especially under vibration or external force, the pipelines are easily crushed, deformed or broken. This utility model can use grouting to protect the pipeline after it passes through the wall, so as to avoid damage to the pipeline.
[0042] 4. This utility model has a wide range of applications. It can be used for pipelines passing through internal walls, waterless or low-pressure water environments, and external walls (without grouting), as well as high-pressure groundwater environments (requiring pressure grouting and secondary grouting).
[0043] 5. The novel through-wall anti-seepage sleeve device of this utility model can be used for later pipeline replacement and maintenance. The sealing ring 3 is detachable, simple to operate, and can be reused and repeatedly sealed.
