Description

Technical Field

[0001] The invention relates to the technical field of building installation and construction, and in particular to a floor heating buried pipe repairing device and a use method thereof. Background Art

[0002] The installation of buried pipes is an important construction link in the construction and installation of floor heating. After the installation of floor heating is completed, especially in the later construction process of decoration, the repair work of the buried pipes is particularly important to avoid accidental damage to the floor heating pipes due to electric hammer drilling.

[0003] In the repair construction of floor heating buried pipes, there are three traditional methods for repairing floor heating buried pipes, ① repair with copper internal plug-in joints ② repair with hot-melt joints ③ repair with outer sleeve joints. All three repair methods require that the completed floor heating covering and filling concrete, including floor tiles, floors and other decorative layers, be chiseled out to create a large and long repair operation space for the buried pipes. In addition, the damaged part of the buried pipe needs to be cut off at least 10 cm in length, and 10 cm of the same material floor heating pipes need to be replenished for repair. The original damaged point of the buried pipe is repaired in two places using two joints, which increases the risk of water leakage at the connection of the buried pipe. At the same time, a large enough repair operation space is needed under the buried pipe for hot-melt tools or clamping tools to enter. It is difficult to chisel out concrete, and special care needs to be taken during construction to prevent damage to the buried pipe again, and the construction efficiency is extremely low.

[0004] At present, a Chinese patent application with the existing patent application number: 'CN201910962463.9' discloses a pipeline repair device, including a repair component and a sleeve component; the repair component includes a seal and an annular clamp; the annular clamp is used to clamp on the pipeline to be repaired, and the seal is arranged between the annular clamp and the pipeline to be repaired to block the leakage point of the pipeline to be repaired, and the sleeve component is sleeved on the outer wall of the annular clamp. The invention first plugs the leakage point on the annular weld through the repair component. In this plugging process, there is no need to stop the transportation of oil and gas. Although it avoids the direct or indirect economic losses caused by the pressure reduction, suspension and emptying of the pipe replacement operation in the prior art, it is still necessary to ensure that there is no gas leakage (or liquid leakage) at the repair position after the repair, or the sealing effect of some positions is weak. If it cannot be discovered in time, subsequent debugging and adjustment are required, which seriously affects the effect and stability of the pipeline sealing.

[0005] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems:

[0006] The repair is cumbersome and the sealing performance of the pipeline after repair cannot be effectively tested; when repairing the existing floor heating buried pipe, the outer sleeve joint is generally used for repair. This method mainly cuts off the worn part of the pipeline, and then connects the pipeline with the outer sleeve joint to the original pipeline instead of the removed buried pipe. This method is time-consuming and labor-intensive, and requires digging a hole of about 10 cm around the buried pipe, which seriously affects the efficiency of the repair. In addition, although a pipeline repair method is also disclosed in the existing solution (patent application number: CN201910962463.9), when the pipeline is repaired, the medium inside the pipeline will leak out through the damaged part, so the seal needs to be fixed to the pipeline with the help of external force, and the common method is manual pressing by the staff, which requires the staff to keep the pressing stable and also needs to install the fixed structure to the outside of the seal, which is not only time-consuming and labor-intensive, but also due to the obstruction of the staff's hands, the fixed structure cannot be accurately installed in place when installing. Secondly, it is impossible to determine whether the seal is completely covered at the damaged part of the pipeline, which seriously affects the efficiency of pipeline repair;

[0007] In addition, after the pipeline repair is completed, it is necessary to test the sealing of the repaired pipeline to ensure that there is no air leakage (or liquid leakage). The existing detection methods mostly rely on manual observation, lack of accuracy, and easy to miss tiny leaks, leading to safety hazards and affecting the long-term stable operation of the pipeline system. For this reason, we propose a floor heating buried pipe repair device and a method of use. Summary of the invention

[0008] 1. Technical issues to be resolved

[0009] In view of the deficiencies in the prior art, the present invention provides a floor heating buried pipe repair device and a method for use, which solve the technical problems in the prior pipeline repair process, that is, the repair is cumbersome and the sealing of the pipeline after repair cannot be effectively detected.

[0010] (II) Technical solution

[0012] A floor heating buried pipe repair device, the repair device comprising:

[0013] Silicone pad;

[0014] A throat clamp is arranged outside the silicone pad and can bind the silicone pad to the damaged part of the buried pipe;

[0015] Wherein, a plurality of air holes are opened on the outside of the silicone pad, and the throat clamp covers the surface of the silicone pad and is located opposite to the air holes.

[0016] Preferably, the extension direction of the pores is consistent with the width direction of the silicone pad;

[0017] Among them, a conduction groove is formed in the middle of the silica gel pad, and the air holes are communicated with the conduction groove. When blowing air into the air holes, the air enters the conduction groove along the air holes;

[0018] When the silica gel pad is installed, the conduction groove on it corresponds to the damaged part on the surface of the buried pipe.

[0019] Preferably, a pipe sleeve is connected to the outside of the silica gel pad, and the silica gel pad is fixed on the buried pipe by using the pipe sleeve. The pipe sleeve includes two interconnected arc-shaped clamping strips, and a connection hook is provided at the end of the arc-shaped clamping strip, and the connection hook翘向外;

[0020] Among them, an extrusion strip is connected between two adjacent connection hooks. The extrusion strip is in a "匚" shape, and the opening faces the arc-shaped clamping strip.

[0021] Preferably, the length of the arc-shaped clamping strip is greater than half of the outer circumference length of the buried pipe.

[0022] Preferably, a placement groove is formed at each end of the silica gel pad. When the pipe sleeve is connected to the silica gel pad, the extrusion strip at the end of the arc-shaped clamping strip is inserted into the placement groove;

[0023] Among them, a meshing groove corresponding to the shape of the pipe sleeve is formed on the side of the silica gel pad facing the pipe sleeve. When the pipe sleeve is connected to the silica gel pad, the pipe sleeve is embedded in the meshing groove.

[0024] Preferably, the hose clamp includes a connection strip and a docking strip that can be docked with each other. The connection strip and the docking strip are respectively connected to the connection hooks at both ends of the arc-shaped clamping strip;

[0025] Among them, an adjusting bolt is provided on the outside of the docking strip. When the connection strip is inserted between the docking strip and the adjusting bolt, the slot hole on the outside of the connection strip corresponds to the thread on the outside of the adjusting bolt.

[0026] Preferably, a connection ring is respectively connected to the ends of the connection strip and the docking strip, and the connection ring is sleeved on the end of the connection hook away from the arc-shaped clamping strip. The connection strip and the docking strip are both movably connected to the connection hook through the connection ring.

[0027] Preferably, when the hose clamp is tightened, the connection hook moves away from the arc-shaped clamping strip in the direction with the connection point between it and the arc-shaped clamping strip as the axis, and at the same time the extrusion strip squeezes towards the buried pipe.

[0028] Preferably, a method for using a repair device for a floor heating buried pipe, the method for using the repair device includes:

[0029] S101. Excavate from 3-4 cm on both sides of the buried pipe and stop when excavating to 1-2 cm below the buried pipe, and clean the burrs at the damaged part on the surface of the buried pipe;

[0030] S102, cover the damaged part of the buried pipe with a silicone pad, and use a hose clamp to tie the silicone pad and the buried pipe together;

[0031] S103. Blow air into the air hole on one side of the silicone pad. If air can pass through the air hole, tighten the throat clamp; otherwise, do not adjust the throat clamp.

[0032] (III) Beneficial effects

[0033] 1. Since the silicone pad is used to cover the damaged part of the buried pipe, and the throat clamp is used to fix the silicone pad on the worn part of the buried pipe, the worn part of the buried pipe is protected. Therefore, the cumbersome technical problem of repair in the existing pipeline repair process is effectively solved, and the rapid repair of the buried pipe is realized. In addition, since the silicone pad is supported by the semicircular arc-shaped clip on the outside, when the silicone pad is installed, it only needs to hold the arc-shaped clip to drive the silicone pad to position, and after installation, since the length of the arc-shaped clip is greater than half of the outer circumference of the buried pipe, the arc-shaped clip can prevent the silicone pad from sliding or moving by grasping the outer wall of the buried pipe, ensuring that the repair effect is stable and reliable.

[0034] 2. By opening a placement groove on the silicone pad and making it correspond to the extrusion strip at the end of the arc-shaped clip strip, the silicone pad and the arc-shaped clip strip can be connected and fixed by inserting the extrusion strip into the placement groove of the silicone pad, reducing the difficulty of assembling the device and ensuring the stability between the two during use; in addition, an outward-curved connecting hook is connected to each end of the arc-shaped clip strip, and the throat hoop is connected to the end of the connecting hook, so when the throat hoop is tightened, the extrusion strip can be driven to extrude in the direction of the silicone pad, thereby sealing the end position of the silicone pad.

[0035] 3. Since the silicone pad with a conducting groove is used to cover the worn part of the underground pipe, and the conducting groove is made to correspond to the worn part of the underground pipe, the worn part of the underground pipe will be connected to the conducting groove, and the air holes outside the silicone pad are consistent with the width direction of the silicone pad, and the arc-shaped card strip corresponds to the position of the air hole. The squeezing force of the arc-shaped card strip on the silicone pad can be judged by detecting whether air can be blown into the air hole. Therefore, the technical problem of being unable to effectively detect the sealing of the pipeline after repair in the existing pipeline repair process is effectively solved, and the sealing of the pipeline after repair is detected, ensuring that the repaired underground pipe is not prone to secondary damage in long-term use, extending the service life of the pipeline, and improving the safety and stability of the overall system. At the same time, it simplifies the operation process, reduces the maintenance cost, and provides an efficient and convenient solution for the maintenance of the floor heating system.

[0050] The embodiment of the present application provides a floor heating buried pipe repair device and a method for using the same, which effectively solves the technical problems in the existing pipeline repair process that the repair is cumbersome and the sealing of the pipeline after repair cannot be effectively detected. In the pipeline repair process, a silicone pad is used to cover the damaged part of the buried pipe, and then a throat clamp is used to fix the silicone pad to the worn part of the buried pipe, thereby protecting the worn part of the buried pipe. In addition, since the silicone pad is supported by a semicircular arc-shaped clip strip on its outside, when installing the silicone pad, it only needs to hold the arc-shaped clip strip to drive the silicone pad for positioning. Moreover, after installation, since the length of the arc-shaped clamping strip is greater than half of the outer circumference of the buried pipe, the arc-shaped clamping strip can prevent the silicone pad from sliding or moving by grasping the outer wall of the buried pipe, thereby ensuring that the repair effect is stable and reliable; since the silicone pad with a conducting groove is used to cover the worn part of the buried pipe, and the conducting groove is made to correspond to the worn part of the buried pipe, the worn part of the buried pipe will be connected to the conducting groove, and the air holes outside the silicone pad are consistent with the width direction of the silicone pad, and the arc-shaped clamping strip corresponds to the position of the air holes, the squeezing force of the arc-shaped clamping strip on the silicone pad can be judged by detecting whether air can be blown into the air holes.

[0051] Embodiment: The technical solution in the embodiment of the present application effectively solves the technical problem that the repair process of the existing pipeline is cumbersome and the sealing of the pipeline after repair cannot be effectively detected. The overall idea is as follows:

[0052] In view of the problems existing in the prior art, the present invention provides a floor heating buried pipe repair device, which mainly includes three parts: a silicone pad 11, a pipe sleeve 2 and a throat clamp 3; the silicone pad 11 is used to wrap the damaged part of the buried pipe, so as to limit the leakage of water in the buried pipe; the pipe sleeve 2 is used to fix the silicone pad 11 and provide support, and firmly fix the silicone pad 11 on the buried pipe; the throat clamp 3 adjusts the extrusion strength of the pipe sleeve 2 on the silicone pad 11 by rotating the adjusting bolt 33, so as to ensure that the silicone pad 11 is tightly fitted to the buried pipe.

[0053] In the specific operation, the silicone pad 11 is first covered on the damaged part, and then the throat clamp 3 is put on the silicone pad 11, and the adjusting bolt 33 on the throat clamp 3 is rotated to tighten it, so as to squeeze the silicone pad 11 in the direction of the pipe sleeve 2 to ensure seamless fit. Through this method, the repair process is simplified.

[0054] It is found in use that if a split silicone pad 11 design is adopted (i.e. the silicone pad 11 is relatively separated from the pipe sleeve 2), when installing the throat clamp 3, the staff needs to first press the silicone pad 11 on the damaged part of the buried pipe with one hand, and then use the other hand to put the throat clamp 3 on the silicone pad 11, and surround the buried pipe for one week, and finally use a screwdriver to rotate the adjustment bolt 33 until the silicone pad 11 fits tightly. In this process, one hand of the staff always needs to be pressed on the silicone pad 11, which makes the operation inconvenient (i.e. the staff's hand needs to occupy a certain space, so when installing the throat clamp 3, it needs to avoid the staff's hand) and takes a long time (the staff needs to complete the installation and fixation of the throat clamp 3 with one hand). Moreover, since the position of the throat clamp 3 cannot be accurately adjusted when operating with one hand, the installation position often deviates, and the staff needs to adjust it back and forth.

[0055] In order to solve the above problems, we have optimized the design of the silicone pad 11 and the pipe sleeve 2, and adopted an "integrated" structure to combine the silicone pad 11 with the pipe sleeve 2 to reduce the installation steps. During operation, you only need to press the silicone pad 11 to the damaged part of the buried pipe, and the silicone pad 11 will be fixed to the buried pipe under the action of the pipe sleeve 2. There is no need to operate the throat clamp 3 with one hand, which greatly improves the installation efficiency and ensures accurate positioning. The specific improved structure is as follows:

[0056] The pipe sleeve 2 is designed to be an arc-shaped structure (arc-shaped clamping strip 21), and the length of the arc-shaped clamping strip 21 needs to be greater than or equal to half of the outer circumference of the buried pipe. In this way, when the arc-shaped clamping strip 21 is installed on the buried pipe, it can embrace the buried pipe, thereby grasping the buried pipe, so that the silicone pad 11 connected to the arc-shaped clamping strip 21 can also be fixed accordingly to ensure a stable installation.

[0057] The silicone pad 11 has a placement groove 13 on both sides. Figure 3 As shown, when the silicone pad 11 is connected to the tube sleeve 2, it is only necessary to align the placement groove 13 on the surface of the silicone pad 11 with the end of the arc-shaped clamping strip 21, so that the silicone pad 11 is connected to the tube sleeve 2, ensuring that the silicone pad 11 is firmly installed. Therefore, it can be operated with one hand.

[0058] During the specific implementation process, the placement groove 13 opened on the surface of the silicone pad 11 is first sleeved correspondingly with the end of the arc-shaped clip 21, so that the silicone pad 11 is fixed to the arc-shaped clip 21, so that the silicone pad 11 is connected to the arc-shaped clip 21, and then the arc-shaped clip 21 with the silicone pad 11 is pressed against the damaged part of the buried pipe, so that the silicone pad 11 corresponds to the damaged part on the surface of the buried pipe. And because the arc-shaped clip 21 is semicircular, it can embrace the buried pipe after installation. Therefore, the silicone pad 11 can also be fixed on the buried pipe without manual pressing by the staff. After that, the adjustment bolt 33 can be rotated by a screwdriver until the silicone pad 11 fits tightly to the buried pipe. The whole process only needs one-handed operation, which is both time-saving and accurate, and effectively avoids the problem of installation position offset.

[0059] After the buried pipe is repaired, the staff is required to check whether the silicone pad 11 is completely in contact with the surface of the buried pipe to ensure that the water in the buried pipe will not leak. The traditional detection method is to wrap one or two layers of toilet paper on the position of the repaired floor heating buried pipe, conduct a water pressure test, and observe the state of the toilet paper to confirm whether the repair is qualified. If the toilet paper remains dry, it proves that the repair is successful; otherwise, the position of the silicone pad 11 needs to be readjusted until there is no leakage. However, this method has certain limitations, that is, it is impossible to perform real-time detection immediately after the installation is completed, so that problems can only be discovered after the water pressure test, which increases the probability of rework.

[0060] In order to reduce the "rework", it is necessary to add a pre-test process before the water pressure test. For this purpose, a placement groove 13 is opened at the joint position of the silicone pad 11 and the buried pipe, and during installation, the placement groove 13 is made to correspond to the damaged part of the surface of the buried pipe. Fig. 9 As shown, at this time, the placement groove 13 is communicated with the interior of the buried pipe.

[0061] A number of pores 12 are provided on the outside of the silicone pad 11 (the pores 12 need to extend from the side of the silicone pad 11 to the conducting groove 14), and the pores 12 are connected to the conducting groove 14 at the center of the silicone pad 11, so that air can enter the conducting groove 14 along the pores 12, and the throat clamp 3 covers the surface of the silicone pad 11 and is opposite to the pores 12 (so that when the throat clamp 3 is tightened, it will squeeze the silicone pad 11, causing the silicone pad 11 to deform, block the pores 12, and squeeze in the direction of the buried pipe at the same time). Utilizing the principle that when the silicone pad 11 is squeezed, it will deform, causing the pores 12 to be blocked, air is introduced into the pores 12 to observe whether the air can flow out smoothly. If the pores 12 cannot be inflated, it means that the silicone pad 11 fits tightly to the buried pipe and there is no risk of leakage; otherwise, it needs to be readjusted until the pores 12 are unobstructed to ensure the quality of the repair. This method is simple and efficient, and greatly reduces the rework rate.

[0062] When the silicone gasket 11 seals the damaged part of the buried pipe, in order to limit the leakage of water between the silicone gasket 11 and the buried pipe, the pipe sleeve 2 is designed into two interconnected arc-shaped clamping strips 21, and correspondingly two throat clamps 3 are also provided. As Figure 2 shown, the spaces on both sides of the damaged part can be blocked in this way; a connection hook 22 is provided at the end of the arc-shaped clamping strip 21, and the connection hook 22翘向外, as Figure 5 shown.

[0063] The throat clamp 3 is mainly divided into two interconnected connection strips 31 and docking strips 32. The connection strips 31 and the docking strips 32 are respectively connected to the connection hooks 22 at both ends of the arc-shaped clamping strip 21. A connection ring is respectively connected to the ends of the connection strips 31 and the docking strips 32, and the connection ring is sleeved on the end of the connection hook 22 far from the arc-shaped clamping strip 21. The connection strips 31 and the docking strips 32 are both movably connected to the connection hook 22 through the connection ring;

[0064] Among them, an adjusting bolt 33 is provided outside the docking strip 32. When the connection strip 31 is inserted between the docking strip 32 and the adjusting bolt 33, the slot on the outside of the connection strip 31 corresponds to the thread on the outside of the adjusting bolt 33. In this way, when the adjusting bolt 33 is rotated, the connection strip 31 can be driven to tighten towards the direction where the docking strip 32 is located, thereby tightening the throat clamp 3 and causing the arc-shaped clamping strip 21 connected to the throat clamp 3 to contract synchronously.

[0065] That is, after the silicone gasket 11 and the pipe sleeve 2 are installed at the damaged part of the buried pipe, as Fig. 9 shown, one end of the connection strip 31 is passed through the gap between the docking strip 32 and the adjusting bolt 33. At this time, the slot on the outside of the connection strip 31 corresponds to the thread on the outside of the adjusting bolt 33. Therefore, by rotating the adjusting bolt 33, the connection strip 31 gradually tightens, driving the arc-shaped clamping strip 21 to contract inward, closely fitting the surface of the buried pipe, and ensuring that the silicone gasket 11 is evenly pressed.

[0066] Since the connection hook 22翘向外 and the throat clamp 3 is connected to the end where the connection hook 22翘向外, when the throat clamp 3 tightens, the connection hook 22 moves away from the arc-shaped clamping strip 21 in the direction with the connection point between it and the arc-shaped clamping strip 21 as the axis, and at the same time, the extrusion strip 23 is extruded towards the buried pipe direction.

[0067] In addition, in order to be able to adapt to the change of the pipe sleeve 2, an extrusion strip 23 is connected between two adjacent connection hooks 22. The extrusion strip 23 is in a "匚" shape and the opening faces the arc-shaped clamping strip 21, as Figure 3 shown. In this way, when the pipe sleeve 2 is connected to the silicone gasket 11, the extrusion strip 23 at the end of the arc-shaped clamping strip 21 is inserted into the placement groove 13. By sleeving the silicone gasket 11 on the extrusion strip 23, the installation between the silicone gasket 11 and the pipe sleeve 2 is completed.

[0068] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
