Description

Technical Field

[0001] This utility model belongs to the field of municipal engineering technology, and more specifically, relates to a rapid sealing and explosion-proof device for perforation of existing protective engineering pipelines. Background Technology

[0002] In municipal engineering, after a building is completed, it is necessary to run pipelines through its walls. Alternatively, during construction, to ensure the structural performance of the wall, the wall may be built first, followed by drilling holes for the pipelines. After the pipelines are installed, the area where they were installed needs to be sealed due to fireproofing, moisture-proofing, and aesthetic requirements. Generally, cement mortar is used for sealing, but this method is not very effective in practice. Firstly, it requires re-forming and grouting, and gaps exist between the old and new cement surfaces, which can lead to peeling after prolonged exposure. Secondly, the material ratios and curing times of the old and new cement cannot be synchronized, resulting in color differences in the walls and affecting the overall appearance of the project.

[0003] Currently, the most common method used in the market is sealing with flange plates. Chinese patent CN116084580B discloses a wall sleeve sealing tool set, including a cap, a first sealing element, a second sealing element, a third sealing element, a fourth sealing element, and a positioning ring. The positioning ring is an open structure made of metal, with an expansion structure at its open end; the fourth sealing element is a circular annular structure made of metal, with a conical inner surface at its front end; the third sealing element consists of two semi-circular rubber components. The conical ring is formed by the insertion and connection of the conical ring. The conical ring of the third sealing component can cooperate with the conical surface on the inner side of the fourth sealing component. The first sealing component is a ring structure formed by the insertion and connection of two semi-circular rings made of plastic. Multiple buckles are provided along the circumference of the inner end of the first sealing component. The second sealing component is formed by the sealing material filled between the first sealing component and the third sealing component. The cap is a ring structure formed by the insertion and connection of two semi-circular rings made of plastic. The cap can be engaged and connected with the first sealing component.

[0004] Chinese patent CN116084580B can effectively control leakage when pipelines of different materials pass through wall sleeves. However, its assembly is still relatively cumbersome, it cannot quickly seal the sleeve, and it cannot be used on existing pipelines. Therefore, there is a need for a rapid sealing and explosion-proof device for perforations of existing protective pipelines, which can quickly install itself to seal the perforations without cutting the pipeline. Utility Model Content

[0005] To address the aforementioned deficiencies or improvement needs of existing technologies, this utility model provides a rapid sealing and explosion-proof device for perforations in existing protective engineering pipelines. This device involves directly enclosing two halves of a sleeve around the pipeline, inserting them into the opening in the wall, and then attaching sealing rings and flange plates to both ends of the sleeve. During on-site assembly, the sleeve is wrapped around the pipeline. Finally, grouting is applied to the gap between the sleeve and the wall to achieve a seal. This avoids the need to cut the pipeline and then reattach the sleeve to seal the hole, ensuring the integrity of the pipeline and preventing subsequent breakage at pipeline joints. The device allows for rapid installation of the perforated pipeline without cutting the pipeline, achieving sealing of the perforation.

[0006] A rapid sealing and explosion-proof device for perforation of existing protective pipelines, comprising: a sleeve and flange plates disposed at both ends of the sleeve;

[0007] The flange plate is fitted onto the end of the sleeve, and a sealing ring is provided between the flange plate and the sleeve. The flange plates at both ends are formed by splicing two half flange pieces together, and the sleeve and the sealing ring are also divided into two halves.

[0008] The sleeve includes a connecting end plate and a first sealing groove. The connecting end plates are used in pairs and are respectively located at both ends of the sleeve. They are annular plates with multiple threaded holes along their circumference.

[0009] The flange plate is fixed to the connecting end plate at both ends of the sleeve, and a sealing ring is provided between the flange plate and the connecting end plate.

[0010] Furthermore, the first sealing groove is also provided in pairs at both ends of the sleeve. It is an annular inner groove with rounded corners and is located on the side of the connecting end plate near the end.

[0011] Furthermore, the flange plate has a second sealing groove at its inner ring, which is also an annular inner groove with rounded corners.

[0012] The sealing ring is located between the first sealing groove and the second sealing groove to seal the connection between the flange plate and the sleeve.

[0013] Furthermore, the sleeve is provided with a pair of abutment plates at both ends. The abutment plates are located on the opposite side of the connecting end plates at both ends, and a gap is reserved between them and the connecting end plates. This gap is an adjustment groove.

[0014] Furthermore, a plurality of limiting rods parallel to the sleeve axis are provided between the two end plates. A push plate is sleeved on the limiting rod. The push plate is an annular plate that is sleeved on the sleeve. A plurality of limiting holes are provided at the corresponding positions of the limiting rods. The limiting rods are located in the limiting holes. The push plate moves along the axial direction of the sleeve along the limiting rods.

[0015] Furthermore, the two half flanges of the flange plate are the first half flange and the second half flange, and both the first half flange and the second half flange are provided with multiple connecting through holes along their circumference. The connecting through holes correspond to the threaded holes on the connecting end plate. Both the first half flange and the second half flange are fixed to the connecting end plate of the sleeve by bolts.

[0016] At one end of the casing for grouting, a first half flange and a second half flange are spliced ​​together, and at the other end of the casing, two second half flanges are spliced ​​together.

[0017] Furthermore, the push plate has a grouting hole, and a grouting pipe is provided on the grouting hole. The connecting end plate and the first half flange are provided with grouting through holes at the corresponding positions of the grouting holes. The grouting pipe passes through the grouting through holes to connect the push plate to the outside of the sleeve.

[0018] Furthermore, a sealing bag is provided near the abutment at one end of the grouting through hole. This bag is annular, with the seal located on the outer ring. Multiple through holes are provided on the sealing bag corresponding to the position of the limiting rod, allowing it to be hung on the limiting rod. The sealing bag contains pre-filled fire-retardant sealant.

[0019] Furthermore, an adjustment ring is provided in the adjustment groove at both ends of the sleeve. The adjustment ring includes a supporting half-ring, which is a half-ring support hoop. A pair of telescopic rods are provided at both ends of the supporting half-ring and outwardly. The ends of the telescopic rods are provided with a support plate, which is an arc-shaped plate.

[0020] In summary, compared with the prior art, the above-described technical solution conceived by this utility model can achieve the following beneficial effects:

[0021] 1. This utility model's rapid sealing device involves directly enclosing two halves of a sleeve around the pipeline, inserting them into openings in the wall, and then fitting sealing rings and flange plates onto both ends of the sleeve. During on-site assembly, the sleeve is wrapped around the pipeline. Finally, grouting is applied to the gap between the sleeve and the wall to achieve a seal. This avoids the need to cut the pipeline and then re-seal the opening, ensuring the integrity of the pipeline and preventing breakage at subsequent pipeline joints. It allows for rapid installation through pipeline perforations, achieving sealing without cutting the pipeline.

[0022] 2. This utility model's rapid sealing device utilizes the thrust of mortar to achieve mobile grouting. This allows the grouting hole to automatically move to follow the mortar saturation point, preventing the mortar closer to the hole from reaching saturation while the mortar further away is insufficient to reach saturation. Mobile grouting avoids gaps at higher points due to mortar not flowing to its full potential. Furthermore, the thrust of the mortar eliminates the need to adjust the speed of the push plate, automatically moving according to the mortar's thrust, resulting in more accurate and reliable grouting placement, improved grouting quality, and prevention of gaps between new and old cement walls that could affect subsequent waterproofing performance.

[0023] 3. The quick sealing device of this utility model adjusts the length of the telescopic rods at both ends according to the required inclination angle of the casing, so as to adjust the position and angle of the casing axis and provide support for the casing, so that the subsequent grouting steps can be completed more stably.

Detailed Implementation

[0033] 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 only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0034] Example 1

[0035] This utility model provides a rapid sealing and explosion-proof device for perforations in existing protective engineering pipelines, including a sleeve 1 and flange plates 4 at both ends of the sleeve 1. The flange plates 4 are fitted onto the ends of the sleeve 1, and sealing rings 5 ​​are provided between the flange plates 4 and the sleeve 1. Each flange plate 4 at both ends is formed by splicing two half-flange pieces. The sleeve 1 and the sealing rings 5 ​​are also divided into two halves. By directly enclosing the two halves of the sleeve 1 onto the pipeline and then inserting them into the opening in the wall, and then fitting the sealing rings 5 ​​and flange plates 4 onto both ends of the sleeve 1, the pipeline is wrapped during on-site splicing. Finally, grouting is applied to the gap between the sleeve and the wall to achieve a seal. This avoids the need to cut the pipeline and then re-fit the sleeve 1 to seal the hole, ensuring the integrity of the pipeline and preventing subsequent breakage at pipeline joints. This allows for rapid installation of the perforated pipeline without cutting the pipeline, achieving sealing of the perforation.

[0036] The sleeve 1 includes a connecting end plate 101 and a first sealing groove 105. The connecting end plates 101 are used in pairs and are respectively located at both ends of the sleeve 1. They are annular plates with multiple threaded holes along their circumference. The first sealing groove 105 is also located in pairs at both ends of the sleeve 1. It is an annular inner groove with rounded corners and is located on the side of the connecting end plate 101 near the end. The inner ring of the flange plate 4 has a second sealing groove 403, which is also an annular inner groove with rounded corners. The sealing ring 5 is located between the first sealing groove 105 and the second sealing groove 403. It is limited and deformed by the inner and outer sealing grooves to seal the connection between the flange plate 4 and the sleeve 1.

[0037] The sleeve 1 is also provided with a pair of abutment plates 102 at both ends. The abutment plates 102 are located on the opposite side of the connecting end plates 101 at both ends, and a gap is reserved between them and the connecting end plates 101. This gap is an adjustment groove 103.

[0038] Between the two end plates 102, there are multiple limiting rods 104 parallel to the axis of the sleeve 1. A push plate 2 is sleeved on the limiting rod 104. The push plate 2 is an annular plate that is sleeved on the sleeve 1. It has multiple limiting holes at positions corresponding to the limiting rods 104. The limiting rods 104 are located in the limiting holes. The push plate 2 moves along the axial direction of the sleeve 1 along the limiting rods 104.

[0039] The two half flanges of the flange plate 4 are the first half flange 401 and the second half flange 402. The first half flange 401 and the second half flange 402 are provided with multiple connecting through holes along their circumference. The connecting through holes correspond to the threaded holes on the connecting end plate 101. The first half flange 401 and the second half flange 402 are both fixed to the connecting end plate 101 of the sleeve 1 by bolts.

[0040] As a further preferred embodiment, after the sleeve 1 is installed into the hole in the wall, grouting is required in the gap between the wall and the sleeve 1 to fix it. Therefore, grouting is required at one end of the sleeve 1. At the grouting end of the sleeve 1, a first half flange 401 and a second half flange 402 are spliced ​​together, and at the other end of the sleeve 1, two second half flanges 402 are spliced ​​together.

[0041] As a further preferred embodiment, the push plate 2 has a grouting hole, and a grouting pipe 6 is provided on the grouting hole. The connecting end plate 101 and the first half flange 401 are provided with grouting through holes at the positions corresponding to the grouting holes. The grouting pipe 6 passes through the grouting through holes to connect the push plate 2 with the outside of the sleeve 1.

[0042] Understandably, grout is injected into the gap between the sleeve 1 and the wall through the grouting pipe 6. Before grouting, the push plate 2 is positioned at the abutment plate 102 at the end furthest from the grouting hole. During grouting, the mortar fills the space between the push plate 2 and the abutment plate 102, generating a pushing force on the push plate 2, pushing it towards the end closer to the grouting hole. Grouting continues during this movement until the gap between the sleeve 1 and the wall is filled. Utilizing the pushing force of the mortar to achieve moving grouting allows the position of the grouting hole to automatically follow the mortar saturation point, preventing the mortar closer to the grouting hole from reaching saturation while the mortar further away from the grouting hole is insufficient and cannot reach saturation. By using mobile grouting, gaps at high points can be avoided due to mortar not being able to flow to the highest point on its own, and the mortar's thrust eliminates the need to adjust the moving speed of the push plate 2. The plate moves automatically according to the mortar's thrust, making the grouting position more accurate and reliable, improving the quality of grouting, and preventing gaps between new and old cement walls that could affect subsequent waterproofing performance.

[0043] As a further preferred embodiment, a sealing bag 3 is also provided near the abutment plate 102 at one end of the grouting through hole. This is a ring-shaped bag with the seal located on the outer ring. The sealing bag 3 has multiple through holes corresponding to the position of the limiting rod 104, and is hung on the limiting rod 104. The sealing bag 3 contains pre-filled fire-retardant sealant.

[0044] Understandably, when the mortar fills the gap between the sleeve 1 and the wall, the push plate 2 and the back plate 102 squeeze the sealing bag 3, causing the seal of the sealing bag 3 to break under the pressure, allowing the fireproof sealant inside to overflow from the seal, and then coating the surface of the mortar with another layer of fireproof sealant to enhance its fireproof performance.

[0045] As a further preferred option, different construction environments may require different inclination angles for the sleeve 1. Therefore, it is necessary to be able to adjust the inclination angle of the sleeve 1. Adjustment rings 7 are provided in the adjustment grooves 103 at both ends of the sleeve 1. Each adjustment ring 7 includes a supporting half-ring 701, which is a semi-circular support clamp. A pair of telescopic rods 702 extend outwards from both ends of the supporting half-ring 701. A support plate 703, which is an arc-shaped plate, is provided at the end of each telescopic rod 702.

[0046] The telescopic rod 702 is composed of multiple nested hollow sleeves. The inner wall of the outer shell is provided with helical grooves or threads, and the surface of the inner core matches the corresponding thread structure. Through rotational drive, the threads mesh with each other to generate friction, which pushes the inner core to move along the axial direction, thereby realizing telescopic movement.

[0047] According to the required inclination angle of the casing 1, the length of the telescopic rods 702 at both ends is adjusted to adjust the position and angle of the casing 1 axis, and to provide support for the casing 1, so that the subsequent grouting steps can be completed more stably.

[0048] As a further preferred embodiment, since the sleeve 1 is a split structure, the push plate 2 and the sealing bag 3 are also split structures, and are arranged opposite each other on the two halves of the sleeve 1. In order to achieve simultaneous movement of the two halves of the push plate 2, the two halves of the push plate 2 are fixed together with bolts after splicing, which also allows the two parts of the sleeve 1 to be initially connected and fixed.

[0049] Example 2

[0050] Based on Example 1, this example sets up a pusher plate 2 without a grouting hole between the grouting space and the abutment plate 102 at the end away from the grouting hole, and also sets a sealing bag 3 on it and the abutment plate 102. After the mortar is filled, the sealing bags 3 at both ends release glue at the same time to achieve a better coating effect of fireproof sealant.

[0051] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
