Description

Technical Field

[0001] The present invention relates to the technical field of sealed sleeves, and particularly relates to a sealed sleeve with an anti-blocking function and a construction method thereof. Background Art

[0002] The existing garbage storage is one of the core components of the negative pressure workshop of a semi-underground hidden garbage comprehensive treatment facility. It is a reinforced concrete garbage storage pool with storage, anti-seepage and anti-corrosion functions, used to receive, store and pre-treat garbage, and adjust the calorific value of garbage. In the normal use state, a large amount of toxic and harmful gases and liquids will be generated from the garbage in the garbage storage.

[0003] Currently, a modular pipe hole sealing device for civil air defense projects is disclosed in a Chinese patent with the publication number: CN111306369B. In view of the problems of the existing perforation sealing method being cumbersome, time-consuming and laborious, the following solution is proposed. It includes a fixing plate, one side of the fixing plate is fixedly installed with a rubber column, and a second jack and a first jack are respectively opened on the fixing plate and the rubber column. The same pipeline is arranged in the second jack and the first jack. One side of the fixing plate is provided with a civil air defense wall, and a reserved hole is opened on the civil air defense wall. A galvanized sleeve is fixedly installed in the reserved hole, and the outer side of the rubber column is in contact with the inner wall of the galvanized sleeve. Two rotating holes are opened on the fixing plate, and rotating rods are threadedly installed in both rotating holes. The sealing method is simple, time-saving and labor-saving, the sealing effect is good, and at the same time, the pipeline can be clamped to increase the stability of the pipeline. The structure is simple and easy to use.

[0004] A sealed through-wall sleeve structure for civil air defense basements is disclosed in a Chinese patent with the publication number: CN114263789B. It includes a sleeve embedded in the wall. A positioning pipe and a sealing pipe are coaxially fitted in the sleeve. The positioning pipe and the sealing pipe are respectively located at both ends of the sleeve. One end of the positioning pipe facing the sealing pipe is coaxially provided with a sealing ring. The sealing ring is coaxially fitted in the sleeve. The sealing ring and the sealing pipe are both used for fitting and sleeving with the pipeline. The sealing ring is also provided with a grouting assembly, which has the effect of making the sealing of the gap between the sleeve and the pipeline simpler and more convenient.

[0005] However, during the implementation of the above technical solutions, it is found that at least the following technical problems exist:

[0006] The sealed sleeve is prone to blockage and cumbersome to use: When the existing garbage sealed sleeve is in use, a sealed sleeve of the corresponding length needs to be selected according to the thickness of the wall, and before pouring, the sealed sleeve needs to be installed into the steel bar framework of the wall. In order to prevent impurities such as concrete from entering the sealed sleeve during pouring (since the length of the sealed sleeve is the same as the thickness of the wall, during the concrete pouring or plastering process, the concrete easily enters the sealed sleeve), the sealed sleeve needs to be blocked in advance, and after pouring, the concrete at the position of the sealed sleeve needs to be knocked out to make the sealed sleeve conduct again. This results in the inability to install complex structures at the end of the sealed pipeline (so it is easily blocked by concrete), which not only limits the use of the sealed sleeve but also increases the convenience of using the sealed sleeve. Therefore, we propose a sealed sleeve with an anti-blocking function and its construction method. Summary of the Invention

[0007] (1) Technical problems to be solved

[0008] In view of the deficiencies of the prior art, the present invention provides a sealed sleeve with an anti-blocking function and its construction method, which solves the technical problems that the existing garbage sealed sleeve is prone to blockage and cumbersome to use when in use.

[0009] (2) Technical solutions

[0010] To achieve the above objectives, the present invention is realized through the following technical solutions:

[0011] A sealed sleeve with an anti-blocking function, the sealed sleeve includes a pipeline, and the pipeline is installed in the steel bar framework to be poured in a buried manner. After fixing, an inflation device (such as a pump) is used to inject air into the injection pipe located on the inner wall of the pipeline. Since one end of the injection pipe is connected to the filling cavity inside the connecting belt, when inflated, the filling cavity inflates. In addition, since one end of the connecting belt is wound around the connecting ring, when the connecting belt is continuously inflated and expanded, the connecting belt wound around the connecting ring can be pulled, causing the connecting belt to continuously unfold, thereby increasing the length of the pipeline, so that the length of the pipeline + the length of the connecting belt after expansion > the thickness of the wall. In this way, during pouring, the pipeline will not be blocked by concrete. In addition, since the inflated connecting belt has a certain hardness and can support the weight of the concrete. After pouring is completed, the connecting belt is deflated, and then a solidifiable substance such as a curing agent is injected into the connecting belt through the injection pipe. After it solidifies, a sleeve is formed, and wires and the like can pass through the sleeve. The above solution is for the case where the volume of concrete poured is small (i.e., the weight of the concrete is small):

[0012] A pipeline, with a connecting belt connected to its end, enabling the connecting belt to extend along the extension direction of the pipeline;

[0013] The storage part is connected to the other end of the connecting belt, and can wind and unwind the connecting belt, thereby reducing the volume of the connecting belt, facilitating carrying and transportation, and avoiding the need to occupy a large amount of space. At the same time, the length of the sleeve (=the length of the pipeline + the length of the expanded connecting belt) can be freely adjusted according to needs, improving the applicability of the device and avoiding the need to customize sleeves of different lengths. In addition, in this application, the connecting belt is used to wrap the medium to protect the medium, while reducing waste of resources and avoiding a large amount of scraps (and welding, etc.) during production, thereby improving the utilization rate of resources;

[0014] Among them, the storage part includes a storage ring, and a connecting ring is embedded inside the storage ring. A plurality of clockwork springs are distributed outside the connecting ring, and the connecting ring is connected to the end of the connecting belt through the clockwork springs. This is like a tape measure. During the process of pulling out the connecting belt, the connecting belt drives the clockwork springs connected to it to rotate together, thereby achieving energy storage, that is, the clockwork springs are constantly storing energy at this time; when the connecting belt is released, the clockwork springs can wind up the connecting belt, making the connecting belt wound around the outside of the connecting ring; a filling cavity is provided inside the connecting belt, and a medium can be filled into the filling cavity. By filling the medium into the filling cavity, the connecting belt can be inflated. At this time, the connecting belt has a certain hardness, so it cannot maintain a normal shape during pouring. Secondly, a curable raw material, such as cement, can be filled into the connecting belt. When it hardens, it has a certain supporting ability and forms a structure with a fixed shape.

[0015] Preferably, the outer diameter of the clockwork spring is larger than the ring width of the connecting ring. This is to ensure that when the connecting belt is wound around the outside of the clockwork spring, the connecting belt does not contact the connecting ring, thereby reducing the friction force when the connecting belt is pulled; one end of the connecting belt is connected to an extension belt, and the connecting belt is connected to the clockwork spring outside the connecting ring through the extension belt, which facilitates connecting the connecting belt and the clockwork spring together. One end of the connecting belt is connected to an extension belt, and the extension belts correspond to the clockwork springs outside the connecting ring one by one; the connecting belt is connected to the clockwork spring outside the connecting ring through the extension belt.

[0016] Preferably, an extension groove is opened at the front end of the storage ring, and one end of the extension groove extends to the position where the connecting ring is located. In this way, when the connecting belt is pulled, the connecting ring cannot be pulled out of the storage ring, thus ensuring the stability of the connecting belt when it is pulled; therefore, the width of the extension groove is larger than the thickness of the connecting belt and smaller than the ring width of the connecting ring.

[0017] Preferably, an injection pipe is installed on the inner wall of the pipeline, and one end of the injection pipe extends into the interior of the connection belt and communicates with the filling cavity inside the connection belt. The medium can be injected into the filling cavity through the injection pipe. When air is injected, the connection belt can expand into a circular ring like a swimming ring, and by adjusting the air pressure, the expanded connection belt has a certain hardness. Secondly, a substance that can quickly solidify can be injected into the connection belt to make the connection belt form a cylindrical shape.

[0018] Preferably, the sealing sleeve further includes a blocking portion, and the blocking portion is connected to the connection belt at the end of the sleeve, which can limit the unfolding length of the connection belt. In this way, the length of the sleeve can be adjusted according to the actual thickness of the wall, improving the applicability of the device. The blocking portion includes a baffle, and a driving member is movably connected to the front end of the baffle. The storage portion can be connected to the driving member, so that the connection belt can be connected to the blocking portion, and thus the blocking portion is arranged on both sides of the sleeve, that is, it fits against both sides of the wall.

[0019] Preferably, the driving member includes an inner ring, and the storage ring can be sleeved outside the inner ring, so that the connection belt is connected to the inner ring. A knob is connected to the front end of the baffle, and one end of the knob extends into the interior of the baffle and is connected to the gear inside the baffle. The gear meshes with the toothed ring on the outer wall of the inner ring. Therefore, when the knob rotates, the inner ring can be driven to rotate, so that the inner ring is connected to the storage ring.

[0020] In addition, in order to fix the connection belt, an extrusion plate is connected to the outer wall of the inner ring. When the storage ring is sleeved on the inner ring, the connection belt is located between the storage ring and the extrusion plate. At this time, the connection belt is clamped by the storage ring and the extrusion plate and cannot move, so that the connection belt cannot perform operations such as elongation.

[0021] Preferably, threads are provided on both the inner and outer sides of the storage ring, and the storage ring can be connected to the inner wall of the pipeline through the external threads. At this time, the connection belt is connected between the pipeline and the storage ring. When the connection belt is inflated, the connection belt expands and extends outwards to form the shape shown in the figure (in addition, the storage ring and the pipe sleeve can also be in the shape of a circular ring with the same radius, and in this case, there is no need to install the storage ring on the inner wall of the pipeline). Through the external threads, it can be connected to the outer wall of the inner ring. At this time, the shape shown in the figure is formed, and the connection belt is clamped by the storage ring and the extrusion plate and cannot move, so that the connection belt cannot perform operations such as elongation.

[0022] (III) Beneficial effects

[0023] 1. Since a spring is used to wind up the connecting belt for the fillable medium, it effectively solves the technical problems that in the existing garbage sealing sleeve, the sealing sleeve is prone to blockage and the use is cumbersome. Furthermore, it achieves the purpose of freely adjusting the length of the sealing sleeve, avoids the need to block the sealing sleeve during pouring, and can also improve the applicability of the device, enabling it to meet the needs of walls with different thicknesses.

[0024] 2. Since a barrier part that can be connected to the storage ring is adopted and the connecting belt is clamped between the two, it achieves the purpose of restricting the elongation length of the connecting belt, avoids being unable to control the length of the connecting belt, makes it applicable to more different needs, and thus improves the applicability of the device.

[0039] In the embodiment of the present application, by providing a sealing sleeve with an anti-blocking function and its construction method, the technical problems that the existing garbage sealing sleeve is easy to be blocked and cumbersome to use during use are effectively solved. When the existing garbage sealing sleeve is used, since a spring is used to wind up the connection belt of the fillable medium, the purpose of freely adjusting the length of the sealing sleeve is realized, avoiding the need to block the sealing sleeve during pouring, and improving the applicability of the device, enabling it to meet the needs of walls with different thicknesses; since a barrier part that can be connected to the storage ring is adopted, and the connection belt is clamped between the two, the purpose of restricting the elongation length of the connection belt is realized, avoiding the inability to control the length of the connection belt and making it applicable to more different needs, thereby improving the applicability of the device.

[0040] Embodiment 1

[0041] The technical solution in the embodiment of the present application effectively solves the technical problems that the existing garbage sealing sleeve is easy to be blocked and cumbersome to use during use. The general idea is as follows:

[0042] Aiming at the problems existing in the prior art, the present invention provides a sealing sleeve with an anti-blocking function. The sealing sleeve includes a sleeve 1, which is composed of a pipe 11, a storage part 12 and an extension part 13 (including a connection belt 131, an extension belt 132 and a filling cavity 133). Among them, the pipe 11 is installed in the steel bar framework to be poured in a pre-buried manner. After fixation, an inflation device (such as a pump) is used to inject air into the injection pipe located on the inner wall of the pipe 11. Since one end of the injection pipe is communicated with the filling cavity 133 inside the connection belt 131, when inflating, the filling cavity 133 inflates and expands. In addition, since one end of the connection belt 131 is wound on the connection ring 122, when the connection belt 131 continuously inflates and expands, it can pull the connection belt 131 wound on the connection ring 122, causing the connection belt 131 to continuously unfold, as Figure 5As shown, the length of the pipeline 11 is increased so that the length of the pipeline 11 + the length of the expanded connecting belt 131 > the thickness of the wall. In this way, when pouring concrete, the situation where the concrete blocks the pipeline 11 will not occur. In addition, since the inflated connecting belt 131 has a certain hardness and can support the weight of the concrete. After the pouring is completed, the connecting belt 131 is deflated, and then a solidifiable substance such as a curing agent is injected into the connecting belt 131 through the injection pipe. After it solidifies, a sleeve is formed, and wires and the like can pass through the sleeve. The above solution is for the case of small concrete pouring volume (i.e., the case of small concrete weight):

[0043] The pipeline 11, with a connecting belt 131 connected to its end, as Figure 4 and Figure 5 shown, can make the connecting belt 131 extend along the extension direction of the pipeline 11, and finally form the shape as Figure 5 shown;

[0044] The storage part 12, connected to the other end of the connecting belt 131, can take in and release the connecting belt 131, thereby reducing the volume of the connecting belt 131, facilitating carrying and transportation, and avoiding the need to occupy a large amount of space. At the same time, the length of the sleeve (=the length of the pipeline 11 + the length of the expanded connecting belt 131) can be freely adjusted according to needs, improving the applicability of the device and avoiding the need to customize sleeves of different lengths. In addition, in this application, the connecting belt 131 is used to wrap the medium to protect the medium and at the same time reduce waste of resources, avoiding the generation of a large amount of scraps (and also welding, etc.) during production, thereby improving the utilization rate of resources;

[0045] Among them, the storage part 12 includes a storage ring 121, and a connecting ring 122 is embedded inside the storage ring 121. A plurality of clockwork springs 123 are distributed outside the connecting ring 122, and the connecting ring 122 is connected to the end of the connecting belt 131 through the clockwork springs 123. Just like a tape measure, in the process of pulling out the connecting belt 131, the connecting belt 131 drives the clockwork springs 123 connected to it to rotate together, thereby achieving energy storage, that is, at this time the clockwork springs 123 are continuously storing energy; when the connecting belt 131 is released, the clockwork springs 123 can wind up the connecting belt 131 so that the connecting belt 131 is wound around the outside of the connecting ring 122, as Figures 6 - 8 shown; A filling cavity 133 is provided inside the connecting belt 131, and a medium can be filled into the filling cavity 133. By filling the medium into the filling cavity 133, the connecting belt 131 can be inflated, as Figure 5 shown. At this time, the connecting belt 131 has a certain hardness, so it cannot maintain a normal shape during pouring. Secondly, a solidifiable raw material such as cement can be filled into the connecting belt 131. When it hardens, it has a certain supporting ability and forms a structure with a fixed shape.

[0046] In some examples, the outer diameter of the spiral spring 123 is greater than the ring width of the connecting ring 122, so that when the connecting belt 131 is wound around the outside of the spiral spring 123, the connecting belt 131 does not contact the connecting ring 122, thereby reducing the friction force when the connecting belt 131 is pulled; one end of the connecting belt 131 is connected with an extension belt 132, and the connecting belt 131 is connected to the spiral spring 123 outside the connecting ring 122 through the extension belt 132, which facilitates connecting the connecting belt 131 and the spiral spring 123 together. One end of the connecting belt 131 is connected with an extension belt 132, and the extension belts 132 correspond one by one to the spiral springs 123 outside the connecting ring 122; the connecting belt 131 is connected to the spiral spring 123 outside the connecting ring 122 through the extension belt 132.

[0047] In some examples, an extension groove is provided at the front end of the receiving ring 121, and one end of the extension groove extends to the position where the connecting ring 122 is located, as Figure 9 shown. In this way, when the connecting belt 131 is pulled, the connecting ring 122 cannot be pulled out of the receiving ring 121, thus ensuring the stability of the pulling of the connecting belt 131; therefore, the width of the extension groove is greater than the thickness of the connecting belt 131 and less than the ring width of the connecting ring 122.

[0048] In some examples, an injection pipe is installed on the inner wall of the pipeline 11, and one end of the injection pipe extends into the connecting belt 131 and communicates with the filling cavity 133 inside the connecting belt 131. A medium can be injected into the filling cavity 133 through the injection pipe. When air is injected, the connecting belt 131 can expand into a circular ring like a swimming ring, and by adjusting the air pressure, the expanded connecting belt 131 has a certain hardness; secondly, a substance that can quickly solidify can be injected into the connecting belt 131, so that the connecting belt 131 forms a cylindrical shape, as Figure 5 shown in the figure.

[0049] In the specific implementation process, it can be divided into the following two usage methods according to needs:

[0050] First, for the case where the pressure that the casing needs to bear during pouring is small

[0051] First, install the pipeline 11 at the specified position. After fixing, use an inflation device (such as a bicycle pump, etc.) to inject air into the injection pipe located on the inner wall of the pipeline 11. Since one end of the injection pipe communicates with the filling cavity 133 inside the connecting belt 131, when inflating, the filling cavity 133 inflates and expands. In addition, since one end of the connecting belt 131 is wound around the connecting ring 122, when the connecting belt 131 continuously inflates and expands, it can pull the connecting belt 131 wound around the connecting ring 122, so that the connecting belt 131 continuously unfolds, as Figure 5As shown in the figure, the length of the pipeline 11 is increased so that the length of the pipeline 11 + the length of the expanded connecting belt 131 > the thickness of the wall. In this way, when pouring concrete, the pipeline 11 will not be blocked by the concrete. In addition, since the inflated connecting belt 131 has a certain hardness and can support the weight of the concrete. After the pouring is completed, the connecting belt 131 is deflated, and then a solidifiable substance such as a curing agent is injected into the connecting belt 131 through the injection pipe. After it solidifies, a casing is formed, and wires and the like can pass through the casing.

[0052] II. Regarding the large pressure that the casing needs to withstand during pouring

[0053] First, install the pipeline 11 at the designated position. After fixing, use an inflation device (such as a bicycle pump) to inject a solidifiable medium into the injection pipe located on the inner wall of the pipeline 11, so that the connecting belt 131 expands. When the expansion length of the connecting belt 131 is close to the required wall thickness, stop inputting the medium. After it solidifies (so that the casing has a certain supporting capacity), inflate the inside of the connecting belt 131 to make the connecting belt 131 expand by inflation, thereby increasing the length of the pipeline 11, so that the length of the pipeline 11 + the length of the expanded connecting belt 131 > the thickness of the wall. In this way, when pouring, the pipeline 11 will not be blocked by the concrete. After the pouring is completed, deflate the connecting belt 131, and the already solidified medium provides a supporting force for the connecting belt 131 so that it will not collapse.

[0054] Embodiment 2

[0055] Based on Embodiment 1, the embodiment of the present application provides a feasible solution for restricting the extension length of the casing. The general idea is as follows:

[0056] The sealed casing further includes a blocking portion 2, and the blocking portion 2 is connected to the connecting belt 131 at the end of the pipeline 11, which can limit the unfolding length of the connecting belt 131. In this way, the length of the casing can be adjusted according to the actual thickness of the wall, improving the applicability of the device; the blocking portion 2 includes a baffle 21, and a driving member 22 is movably connected to the front end of the baffle 21; the storage portion 12 can be connected to the driving member 22, so that the connecting belt 131 and the blocking portion 2 can be connected together to form a shape as Figure 1 shown in the figure, so that the blocking portion 2 is disposed on both sides of the casing, that is, it fits against both sides of the wall.

[0057] In some examples, the driving member 22 includes an inner ring 221, and the receiving ring 121 can be sleeved outside the inner ring 221, so that the connecting belt 131 is connected to the inner ring 221; a knob 23 is connected to the front end of the baffle 21, and one end of the knob 23 extends into the baffle 21 and is connected to the gear 223 inside the baffle 21; the gear 223 meshes with the tooth ring 222 on the outer wall of the inner ring 221, so when the knob 23 rotates, the inner ring 221 can be driven to rotate, so that the inner ring 221 and the receiving ring 121 are connected together.

[0058] In addition, in order to fix the connecting belt 131, an extrusion plate is connected to the outer wall of the inner ring 221. When the receiving ring 121 is sleeved on the inner ring 221, the connecting belt 131 is located between the receiving ring 121 and the extrusion plate (there is a gap between adjacent extrusion plates). At this time, the connecting belt 131 is clamped by the receiving ring 121 and the extrusion plate and cannot move, so that the connecting belt 131 cannot perform operations such as elongation.

[0059] In some examples, internal and external threads are provided on both sides of the receiving ring 121, and the receiving ring 121 can be connected to the inner wall of the pipe 11 through the external thread. At this time, the connecting belt 131 is connected between the pipe 11 and the receiving ring 121. When the connecting belt 131 is inflated, the connecting belt 131 expands and extends outwards to form as Figure 5 the shape shown (in addition, the receiving ring 121 can also be in the shape of a circular ring with the same radius as the sleeve, and in this case, there is no need to install the receiving ring 121 on the inner wall of the pipe 11), and it can be connected to the outer wall of the inner ring 221 through the external thread. At this time, it forms as Figure 12 the shape shown, and the connecting belt 131 is clamped by the receiving ring 121 and the extrusion plate and cannot move, so that the connecting belt 131 cannot perform operations such as elongation.

[0060] In the specific implementation process, for the two usage cases of the sleeve, the use of the barrier portion 2 also falls into two cases;

[0061] First, when the sleeve is in the first case, after the pouring is completed, the connecting belt 131 is deflated. As the connecting belt 131 is continuously deflated, the connecting belt 131 is driven by the spring 123 and is not only wound into the receiving ring 121. Then, the receiving ring 121 is removed from the pipe 11, and then the receiving ring 121 is connected to the inner ring 221, and the knob 23 outside the baffle 21 is rotated. Since one end of the knob 23 is connected to the gear 223, and the gear 223 meshes with the tooth ring 222 outside the inner ring 221, when the knob 23 rotates, the inner ring 221 can be driven to rotate. And part of the connecting belt 131 is adhered to the concrete during the pouring process. Therefore, when the inner ring 221 rotates, the receiving ring 121 does not rotate, so that the receiving ring 121 is connected to the inner ring 221 to form as Figure 12In the shown shape, at this time, the connecting belt 131 is clamped by the receiving ring 121 and the pressing plate and cannot move. In this way, the connecting belt 131 cannot perform operations such as elongation, and the installation of the blocking part 2 is completed.

[0062] Second, when the sleeve is in the second case, after pouring, the connecting belt 131 is deflated. At this time, the receiving ring 121 can be connected to the inner ring 221, and the knob 23 is rotated. Since some of the connecting belt 131 has been filled with curable solidifying material during pouring, the receiving ring 121 does not rotate when the inner ring 221 rotates.

[0063] After the installation of the blocking part 2 is completed, the sealing strip 3 is installed in the inner ring 221. Then, the wire is passed through the through hole in the sealing strip 3, and the wire can pass through the sleeve 1. Then, the connecting belt 131 is inflated so that the restarted connecting belt 131 blocks the gap between the wire and the sleeve 1 and prevents the wire from contacting the inner wall of the sleeve 1.

[0064] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention and are not limitations on the implementation manners. For those of ordinary skill in the art, 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 manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
