Description

Technical Field

[0001] This utility model relates to the field of pipe jacking connection and installation technology, and in particular to a pipe jacking connection and installation structure. Background Technology

[0002] Pipe jacking is a trenchless pipeline laying technology used in municipal construction. Its advantages include minimal or no impact on the surrounding environment, small construction site size, low noise, and the ability to operate deep underground—advantages unmatched by open-cut pipe laying. During pipe jacking construction, connecting structures are needed to link adjacent pipe components.

[0003] Application No. 202110240675.3 proposes an auxiliary facility for pipe jacking construction, which effectively prevents axial misalignment between the front and rear pipe sections by setting up the insertion pipe. However, in order to achieve the limiting effect, the outer wall of the insertion pipe needs to be completely fitted with the inner wall of the slot. This results in greater resistance during the pipe section connection and pushing process, which may cause the insertion pipe to not be fully inserted into the slot, affecting the connection effect. Utility Model Content

[0004] This utility model discloses a pipe connection and installation structure, which aims to solve the technical problem that in order to achieve the limiting effect, the outer wall of the insertion pipe needs to be completely fitted with the inner wall of the slot, which results in greater resistance during the pipe section connection and pushing process, and may cause the insertion pipe to not be fully inserted into the slot, thus affecting the connection effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pipe jacking connection and installation structure includes a pipe body, and further includes:

[0007] The external connection mechanism is located at both ends of the tube body to provide guidance and limit for the connection of two adjacent tube bodies, and to increase the friction at the connection point of the two tube bodies near the outer circumference, making the connection between the two more stable.

[0008] An internal connection mechanism is located at both ends of the tube and is used to establish a connection between two adjacent tubes near the inner circumferential wall.

[0009] A sealing ring is installed between two adjacent pipe bodies;

[0010] The external connection mechanism includes:

[0011] Multiple external grooves are equidistantly arranged on one side of the inner wall of the pipe body;

[0012] Multiple inner grooves are equidistantly arranged on the inner wall of the pipe body, and are fixedly connected to multiple outer grooves one by one;

[0013] The external connection mechanism also includes:

[0014] Multiple connecting sleeves are movably inserted into multiple inner grooves, and each connecting sleeve has a through groove on both sides.

[0015] Multiple sealing gaskets are fixedly attached to the outer wall of multiple connecting sleeves;

[0016] Multiple sealing gaskets are fixedly attached to the inner walls of multiple connecting sleeves, and sealing gaskets 1 and 2 are set within the setting range of the groove;

[0017] The external connection mechanism also includes:

[0018] Multiple cylindrical inserts are fixedly connected at equal intervals to one side of the outer wall of the tube;

[0019] Multiple tapered inserts are fixedly connected to the outer ends of multiple tubes, and the cylindrical inserts and tapered inserts are inserted into multiple connecting sleeves respectively.

[0020] With the external connection mechanism, when the two tubes are joined, multiple tapered rods can be inserted into each connecting sleeve for auxiliary positioning. The tapered rods simplify the initial insertion. As the connection is continuously pushed, the cylindrical rods are pushed into the connecting sleeves, causing the connecting sleeves to expand outward from the groove. Through forced expansion, radial elastic deformation is formed. With the double-sided adhesion of sealing gasket one and sealing gasket two, pressure is simultaneously applied to the inner wall of the outer groove and the outer wall of the cylindrical rods, achieving engagement of the cylindrical rods and increasing the extraction resistance. This reduces the difficulty of initial assembly while ensuring the stability of the connection in the later stages.

[0021] In a preferred embodiment, the internal connection mechanism includes:

[0022] Multiple slots are equidistantly arranged on the inner circumference of the tube;

[0023] The insert is fixedly connected to the outer wall of the other end of the tube body. A groove is provided on one side of the inner wall of the tube body, and the insert is inserted into the groove.

[0024] Multiple mounting slots are equidistantly distributed on the outer circumference of the bracket;

[0025] The internal connection mechanism also includes:

[0026] Multiple springs are fixedly connected to multiple mounting slots;

[0027] Multiple protrusions are fixedly connected to multiple springs, and each protrusion has a chamfer on one side of its inner wall.

[0028] With an internal connection mechanism, when two adjacent tubes are installed, the corresponding insert is inserted into the groove. At the same time, the spring pushes the protrusion into the slot to complete the connection. This structure can work with the external connection mechanism to achieve the connection between the inner and outer layers, thereby achieving double locking and further ensuring the sealing of the tube connection. When the protrusion is inserted, the insert squeezes the sealing ring, thus ensuring the airtightness of the connection.

[0029] In a preferred embodiment, the sealing ring is embedded in the inner wall of one side of the groove, and multiple air holes are equidistantly arranged on the sealing ring, with the through direction of the air holes being consistent with the setting direction of the pipe body.

[0030] By incorporating multiple air vents, space can be provided for compression, and based on the resilience of the sealing ring, the air vents are reverse-pressed against the outer surface of the insert, thereby enhancing the reverse compression force of the sealing ring to further ensure the airtightness of the tube connection.

[0031] As described above, a pipe jacking connection and installation structure includes a pipe body and further includes: an external connecting mechanism disposed at both ends of the pipe body, used to provide guidance and limitation for the connection of two adjacent pipe bodies, and to increase the frictional force at the connection point of the two pipe bodies near the outer circumferential wall, making the connection more stable; an internal connecting mechanism disposed at both ends of the pipe body, used to establish the connection at the connection point of the two adjacent pipe bodies near the inner circumferential wall; and a sealing ring disposed between two adjacent pipe bodies. The pipe jacking connection and installation structure provided by this utility model reduces the difficulty of initial assembly while ensuring the stability of the connection in the later stages.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0038] The pipe jacking connection installation structure disclosed in this utility model is mainly used in pipe jacking connection scenarios.

[0039] Reference Figure 1 A pipe jacking connection and installation structure includes a pipe body 1, and further includes:

[0040] The external connection mechanism 2 is located at both ends of the tube body 1. It is used to provide guidance and limit for the connection of two adjacent tube bodies 1 and increase the friction force at the connection point of the two tube bodies 1 near the outer circumferential wall, so that the connection between the two is more stable.

[0041] The inner connection mechanism 4 is located at both ends of the tube body 1 and is used to establish a connection between two adjacent tube bodies 1 near the inner circumferential wall.

[0042] The sealing ring 3 is placed between two adjacent pipe bodies 1.

[0043] Reference Figure 2 In a preferred embodiment, the external connection mechanism 2 includes:

[0044] Multiple outer grooves 204 are equidistantly arranged on one side of the inner wall of the tube body 1;

[0045] Multiple inner grooves 203 are equidistantly arranged on the inner wall of the tube body 1, and are fixedly connected to multiple outer grooves 204 one by one.

[0046] Reference Figure 2 In a preferred embodiment, the external connection mechanism 2 further includes:

[0047] Multiple connecting sleeves 207 are movably inserted into multiple inner grooves 203, and each connecting sleeve 207 has a through groove 208 on both sides.

[0048] Multiple sealing gaskets 206 are fixedly attached to the outer wall of multiple connecting sleeves 207;

[0049] Multiple sealing gaskets 205 are fixedly attached to the inner walls of multiple connecting sleeves 207, and sealing gaskets 206 and 205 are disposed within the setting range of the groove 208.

[0050] Reference Figure 1 In a preferred embodiment, the external connection mechanism 2 further includes:

[0051] Multiple cylindrical inserts 202 are fixedly connected at equal intervals to one side of the outer wall of the tube body 1;

[0052] Multiple tapered inserts 201 are fixedly connected to the outer ends of multiple tube bodies 1, and cylindrical inserts 202 and tapered inserts 201 are correspondingly inserted into multiple connecting sleeves 207. When two tube bodies 1 are joined, auxiliary positioning can be achieved by inserting multiple tapered inserts 201 into each connecting sleeve 207. Since the front diameter of the tapered insert 201 is smaller than that of the rear diameter, the initial insertion is simpler, and excessive friction will not affect the complete insertion of the tapered insert 201. With continuous pushing, the tapered inserts 202 and 201 are inserted into the connecting sleeves 207. 1. A cylindrical insert 202 with the same maximum diameter is pushed into the connecting sleeve 207, causing the connecting sleeve 207 to expand outward from the groove 208. Through forced expansion, radial elastic deformation is formed. Under the double-sided adhesion of the sealing gasket 1 205 and the sealing gasket 206, the pressure is simultaneously applied to the inner wall of the outer groove 204 and the outer wall of the cylindrical insert 202, thereby achieving the engagement of the cylindrical insert 202 and increasing the extraction resistance. This reduces the difficulty of the initial assembly and ensures the stability of the connection in the later stage.

[0053] Reference Figure 1 and Figure 3 In a preferred embodiment, the inner connection mechanism 4 includes:

[0054] Multiple slots 401 are equidistantly arranged on the inner circumference of the tube body 1;

[0055] The bracket 402 is fixedly connected to the outer wall of the other end of the tube body 1. A groove 5 is provided on one side of the inner wall of the tube body 1, and the bracket 402 is inserted into the groove 5.

[0056] Multiple mounting slots 403 are equidistantly distributed on the outer circumference of the bracket 402.

[0057] Reference Figure 3 In a preferred embodiment, the inner connection mechanism 4 further includes:

[0058] Multiple springs 405 are fixedly connected to multiple mounting slots 403 respectively;

[0059] Multiple protrusions 406 are fixedly connected to multiple springs 405, and each protrusion 406 has a chamfer 404 on one side of its inner wall. When two adjacent tubes 1 are installed, the corresponding insert 402 is inserted into the groove 5. As the insert 402 is continuously pushed in, the protrusion 406 hidden in the mounting groove 403 moves to one side of the slot 401 and is pushed into the slot 401 by the spring 405 to complete the connection. The chamfer 404 can directly retract the protrusion 406 into the mounting groove 403 by contacting the outer wall of the tube 1 during the pushing process of the insert 402. In this structure, the inner and outer layers can be connected together with the outer connection mechanism 2 to achieve double locking and further ensure the sealing of the tube 1 connection. At the same time, when the protrusion 406 is inserted, the insert 402 just squeezes the sealing ring 3, thus ensuring the sealing of the connection.

[0060] Reference Figure 4 In a preferred embodiment, the sealing ring 3 is embedded in the inner wall of one side of the groove 5. Multiple air holes 6 are equidistantly arranged on the sealing ring 3, and the through direction of the air holes 6 is consistent with the setting direction of the tube body 1. By increasing the overall thickness of the sealing ring 3, the multiple air holes 6 can provide space for the compression position when the bracket 402 compresses the sealing ring 3. Based on the resilience of the sealing ring 3, it is compressed against the outer surface of the bracket 402 in the opposite direction. By enhancing the reverse compression force of the sealing ring 3, the airtightness of the connection of the tube body 1 is further guaranteed.

[0061] Working principle: When two tubes 1 are joined, multiple tapered inserts 201 can be inserted into each connecting sleeve 207 for auxiliary positioning. Since the front diameter of the tapered insert 201 is smaller than that of the rear diameter, the initial insertion is simpler and the complete insertion of the tapered insert 201 is not affected by excessive friction. With continuous pushing, the cylindrical insert 202, which has the same maximum diameter as the tapered insert 201, is pushed into the connecting sleeve 207, causing the connecting sleeve 207 to be pushed outward from the groove 208. Through forced expansion, radial elastic deformation is formed, and under the double-sided adhesion of the sealing gasket 1 205 and the sealing gasket 206, the pressure is simultaneously applied to the inner wall of the outer groove 204 and the outer wall of the cylindrical insert 202, so as to achieve the engagement of the cylindrical insert 202, thereby increasing the extraction resistance. Thus, while reducing the difficulty of the initial assembly, it also ensures the stability of the connection in the later stage.

[0062] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
