Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, and in particular to a receiving sleeve device with an irregular cross-section. Background Technology

[0002] In the construction of T-shaped tunnels, such as connecting passages, underground utility tunnels, and highway tunnels, the excavating body advances along the soil towards the opposite tunnel. A receiving sleeve is installed on the tunnel segments of the opposite tunnel. The excavating body breaks through and enters the receiving sleeve, thus enabling its retrieval. The receiving sleeve is fixedly connected to the tunnel segments. For example, document CN223136131U discloses a receiving sleeve device for tunnel construction equipment.

[0003] Existing tunneling equipment uses a circular tunneling body for constructing circular T-shaped tunnels. During tunnel use, the lower half needs to be filled to create a transport plane, increasing the excavation space and impacting construction efficiency. Rectangular tunnel structures not only create a flat transport plane but also require less excavation space for the same tunnel width. Existing receiving sleeve devices are unsuitable for rectangular excavation tunneling bodies, and the directional nature of the rectangular tunneling body entering the receiving sleeve poses a technical problem of impact on the sleeve if deviation occurs. Therefore, improvements are needed. Utility Model Content

[0025] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the present invention. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art.

[0026] like Figures 1 to 4 As shown, this utility model provides an irregular cross-section receiving sleeve device, which includes a cylindrical assembly with an irregular cross-section tubular structure. The cylindrical assembly is a cylindrical structure with one end open and the other end closed. The cross-section of the cylindrical assembly perpendicular to its length is a ring structure, and the closed part is rectangular. The irregular cross-section receiving sleeve device has a rectangular receiving space, which can be adapted to accommodate a rectangular tunneling body. The irregular cross-section receiving sleeve device is fixed to the corresponding installation area. The tunneling body excavates and breaks through the tunnel lining structure of the corresponding construction area, thereby entering the receiving sleeve device.

[0027] The "irregular cross-section" described in this utility model refers to a non-circular cross-sectional structure that differs from a standard circle, including but not limited to rectangular, rectangular-like (such as chamfered rectangles and rounded rectangles), elliptical, runway-shaped, horseshoe-shaped, and polygonal structures. The "tunneling equipment" described in this utility model refers to mechanical equipment used for underground space excavation. The main tunneling component is the host unit that performs the tunneling function, encompassing both shield tunneling machines (using the shield tunneling method) and pipe jacking machines (using the pipe jacking method). The "tunnel lining structure" described in this utility model encompasses assembled tunnel segments used in shield tunneling and prefabricated tunnel sections used in pipe jacking.

[0028] The irregular cross-sectional structure includes, but is not limited to, quadrilateral tubular structures, as well as related rectangular structures. For example, the sleeve body 10 of the irregular cross-sectional tubular structure is a rectangular or square structure with two parallel sides and intersecting side walls; or, the sleeve body 10 of the irregular cross-sectional tubular structure is a rounded rectangular structure with two parallel sides and four corners connected by curved wall structures, or a chamfered rectangular structure with four corners connected by curved wall structures; or, the sleeve body 10 of the irregular cross-sectional tubular structure has parallel upper and lower side walls and left and right side walls connected by arcs or curved surfaces to form a racetrack-shaped structure; or, the cross-section of the sleeve body 10 is an elliptical structure.

[0029] The sleeve assembly includes a sleeve body 10 and a sleeve tail cap 30 detachably connected to the sleeve body 10, which closes the sleeve body 10. The sleeve body 10 has a rectangular annular structure with a front flange ring 13 at one end and a tail flange ring 33 at the opening of the sleeve tail cap 30. The front flange ring 13 and the tail flange ring 33 are locked together by fasteners. The sleeve body 10 and the sleeve tail cap 30 are locked together by multiple fasteners, which facilitates disassembly and replacement of different connection lengths while maintaining controllable locking force at the mating surfaces and ensuring good sealing performance.

[0030] Furthermore, the sleeve tail cover 30 includes a rectangular tail tube 31 and a tail cover plate 32. The rectangular tail tube 31 is a rectangular tubular structure, and the length dimension of the cylinder assembly can be changed by adjusting the rectangular tail tubes 31 of different lengths, thereby adapting to tunneling bodies of different sizes. The tail cover plate 32 is a plate-like structure that closes the opening of the rectangular tail tube 31, so that the sleeve tail cover 30 forms a cylindrical container structure. The tail flange ring 33 is located at the opening at the other end of the rectangular tail tube 31, and the front flange ring 13 is located at the end of the sleeve body 10. Both the tail flange ring 33 and the front flange ring 13 have multiple aligned through holes, through which bolts pass and are locked by nuts.

[0031] Preferably, multiple guide blocks 20 are installed on the inner wall of the sleeve body 10, with the length direction of the guide blocks 20 extending along the length direction of the sleeve assembly. The guide blocks 20 are distributed on opposite side walls of the sleeve body 10, adjusting the posture and angle of the tunneling body entering the sleeve body 10. Alternatively, the guide blocks 20 are distributed around the sleeve body 10, thereby circumferentially adjusting and limiting the posture and angle of the tunneling body entering the sleeve body 10. Preferably, each side wall of the sleeve body 10 may have two or more guide blocks 20, thereby achieving comprehensive limitation of the sliding direction of the tunneling body by multiple guide blocks 20.

[0032] Furthermore, the guide block 20 is provided with a guide surface 21, which is inclined towards the opening direction of the sleeve body 10. The guide surface 21 can be set as an arc-shaped curved surface or an inclined surface, so that the cross-sectional thickness of the guide block 20 gradually increases from the opening direction towards the sleeve tail cap 30. When the tunneling body enters the sleeve body 10, the tunneling body can gradually center itself under the guidance of the guide surface 21. Preferably, the guide block 20 has a straight wall in the area behind the guide surface 21, which can adjust the centering of the tunneling body. Multiple guide blocks 20 are set on the inner wall of the sleeve body 10, and the guide surface 21 can gradually correct the offset direction of the tunneling body, thereby keeping the tunneling body and the sleeve body 10 coaxial.

[0033] The irregularly shaped receiving sleeve device is connected and fixed to the corresponding installation area of ​​the tunnel to secure the receiving sleeve device and the tunnel as a whole. The open end face of the sleeve body 10 is provided with a mating surface, the curvature of which matches the curvature of the tunnel installation area surface. The mating surface is located at the opening of the sleeve body 10, and its adaptation to the curvature of the installation area surface forms a complementary mating structure with high tightness.

[0034] The mating surfaces of the cylinder assembly and the connecting surfaces of the tunnel segments fit together closely, facilitating welding and fixing of the cylinder assembly and its accessories to the embedded parts. This results in a high degree of tightness and good sealing. Optionally, the mating surfaces can be planar or curved to adapt to the surface morphology of the connected parts. Specifically, when the connected part is a planar manhole wall structure, the mating surface of the cylinder assembly is set to a planar surface. When the connected part is the main circular tunnel section, the mating surface of the cylinder assembly is set to a curved surface to adapt to the curved shape of the main tunnel.

[0035] Optionally, the sleeve body 10 is configured as an integral ring structure to maintain high structural strength.

[0036] like Figures 4 to 7 As shown, the sleeve body 10 has a combinable structure for easy transportation and manufacturing. In one embodiment, the sleeve body 10 includes an upper sleeve 12 and a lower sleeve 11, which fit together to form an irregularly shaped cross-section tube structure. In an optional embodiment, the upper sleeve 12 and the lower sleeve 11 are welded together to form an integral structure.

[0037] Both the upper sleeve 12 and the lower sleeve 11 are fixedly connected to the sleeve end cap 30, and the mating surfaces of the upper sleeve 12 and the lower sleeve 11 intersect with the end face of the sleeve end cap 30. The connecting surfaces of the upper sleeve 12 and the lower sleeve 11 are perpendicular to the connecting surfaces of the sleeve body 10 and the sleeve end cap 30, thus forming a T-shaped connection distribution structure, which is convenient for disassembly and assembly and easy for transportation.

[0038] In one embodiment, the upper sleeve 12 and the lower sleeve 11 are approximately U-shaped. The lower sleeve 11 includes a left wall 16, a bottom wall 15, and a right wall 17, while the upper sleeve 12 includes a left wall 16, a top wall 14, and a right wall 17. The bottom wall 15 and the top wall 14 are positioned opposite each other, and the left wall 16 and the right wall 17 are positioned opposite each other. The left wall 16 and the right wall 17 intersect at both sides of the bottom wall 15, forming a U-shaped structure.

[0039] Optionally, the left wall 16 and the bottom wall 15 intersect directly to form an intersecting right-angled wall structure, and the irregular cross-section tube structure can form a regular rectangular structure or a square structure. Optionally, the intersection of the left wall 16 and the bottom wall 15 is arc-shaped, thereby forming an arc-shaped chamfered structure, and the irregular cross-section tube structure can form a rectangular structure or a square structure with arc-shaped chamfered corners. Optionally, the intersection of the left wall 16 and the bottom wall 15 is an inclined wall, thereby forming an inclined chamfered structure, and the irregular cross-section tube structure can form a polygonal tube structure with inclined chamfered corners.

[0040] To facilitate the maintenance and use of the cylinder assembly, the cylinder assembly includes multiple reinforcing ribs 40 fixed to its outer peripheral wall. The reinforcing ribs 40 are distributed along the outer peripheral wall of the cylinder assembly, forming a grid-like reinforcing mesh structure. Specifically, the reinforcing ribs 40 are distributed on the outer surface of the sleeve body 10 and the outer surface of the sleeve tail cap 30.

[0041] To facilitate internal inspection and maintenance of the cylinder assembly, the cylinder assembly is equipped with at least one personnel compartment opening 41 and a corresponding personnel compartment door 42, with the personnel compartment opening 41 located on one side of the cylinder assembly. For example, in a non-circular cross-section receiving sleeve device, the sleeve is fixed horizontally to the tunnel segment, with at least one personnel compartment opening 41 penetrating the lower sleeve 11, and the personnel compartment door 42 correspondingly installed on the lower sleeve 11, controlling the opening and closing of the personnel compartment opening 41. Preferably, two personnel compartment openings 41 are provided, respectively located on opposite sides of the lower sleeve 11, with the personnel compartment openings 41 close to the opening area of ​​the cylinder assembly, allowing operators to enter the cylinder assembly from both sides of the personnel compartment openings 41.

[0042] The personnel compartment door 42 is fitted and sealed to the personnel compartment opening 41 to keep the opening 41 closed. During inspection or maintenance, the personnel compartment door 42 is removed for repair. Preferably, the cylinder assembly is rectangular, and the personnel compartment opening 41 is located on the plane of the vertical wall, improving the flatness of the opening 41 and facilitating the sealing of the personnel compartment door 42. Preferably, the personnel compartment door 42 and the personnel compartment opening 41 are detachably connected by multiple fasteners, maintaining both the operability of the personnel compartment door 42 and the sealing of the personnel compartment opening 41.

[0043] In one embodiment, the cylinder assembly includes at least one injection port 43, a discharge port 44, and a functional interface 45. The functional interface 45 is located on the side wall or at a corner of the cylinder assembly. The opening height of the injection port 43 is greater than the opening height of the discharge port 44, through which grout can be discharged. The injection port 43 is used to inject grout into the cylinder assembly, and the discharge port 44 is used to discharge grout from the cylinder assembly. The injection port 43 and the discharge port 44 can coordinate to regulate the internal pressure of the cylinder assembly, thereby achieving controllable internal pressure.

[0044] Furthermore, at least one slurry discharge port 44 connects to the lower region of the cylinder assembly to link the internal and external spaces of the cylinder assembly, thereby facilitating the discharge of slurry from the cylinder assembly. Operators can empty the slurry from the cylinder assembly by controlling the opening of the slurry discharge port 44, facilitating inspection or maintenance of the cylinder assembly's interior. Preferably, the height of the slurry discharge port 44 is lower than the height of the manhole 41 to ensure that the slurry in and above the manhole 41 can be emptied. Furthermore, four slurry discharge ports 44 are provided, symmetrically distributed on both sides of the cylinder assembly, and positioned below the manhole 41.

[0045] like Figures 4 to 6 As shown, a grouting port 43 is provided at the top of the cylinder assembly. The grouting port 43 is connected to the cylinder assembly and can be connected to a grouting device to inject grout. Preferably, there are two or more grouting ports 43 to improve the grout injection efficiency. For example, two grouting ports 43 are provided, with the two grouting ports 43 respectively located on the upper sleeve 12 and the sleeve tail cap 30.

[0046] Furthermore, the cylinder assembly includes at least one functional interface 45, which can be connected to a testing instrument capable of detecting parameters within the cylinder assembly. For example, the functional interface 45 can be configured as a pressure gauge interface, allowing connection of a pressure gauge to detect the slurry pressure within the cylinder assembly. The functional interface 45 can be located on the top or upper region of the sidewall of the cylinder assembly, thereby enabling the detection of relevant parameters within the cylinder assembly.

[0047] In one embodiment, the irregular cross-section receiving sleeve device further includes two guide rails 50 spaced apart on the cylinder assembly, extending from the open end toward the sleeve tail cover 30. The two guide rails 50 are fixed to the bottom wall 15 of the lower sleeve 11, providing support for the tunneling body to maintain an opening between the tunneling body and the lower surface of the cylinder assembly, reducing friction between the tunneling body and the bottom wall 15. Preferably, the guide rails 50 are provided with guide ramps; alternatively, the cylinder assembly is equipped with a receiving block located at one end of the guide rail 50, and the receiving block is provided with guide ramps. The guide ramps guide the tunneling body to gradually align with the launching sleeve device, preventing impact and collision between the tunneling body and the guide rails 50.

[0048] Preferably, the top of the guide rail 50 has multiple elongated grooves for lubrication, with the grooves arranged in parallel. Alternatively, the top of the guide rail 50 has multiple recessed lubrication holes, which are circular. The lubrication grooves and holes can increase the grease capacity on the surface of the guide rail 50, thereby reducing the frictional resistance of the tunneling body.

[0049] In one embodiment, the irregular cross-section receiving sleeve device includes a base assembly 60 installed at the bottom of the cylindrical assembly. The base assembly 60 suspends the cylindrical assembly, thereby allowing adjustment of the installation height of the cylindrical assembly. The base assembly 60 includes a support plate 62 and multiple support seats 61. The support plate 62 has a plate-like structure, and the multiple support seats 61 are welded and fixed to the support plate 62 at intervals, making them a single unit. The support plate 62 is arranged along the lower width direction of the bottom wall 15 and is connected to the bottom of the cylindrical assembly. The support seats 61 support the cylindrical assembly. The support seats 61 are erected on the foundation surface of the tunnel, thereby suspending the cylindrical assembly. Preferably, the support seats 61 are configured as I-beams or rectangular beams.

[0050] Furthermore, the guide rail 50 is located above and parallel to the support base 61, and extends from the sleeve body 10 to the sleeve tail cover 30. The guide rail 50 is provided on the bottom wall 15, and its length direction is parallel to the support base 61, so that the tunneling body can transfer gravity to the base assembly 60 through the guide rail 50.

[0051] To facilitate the position movement and angle adjustment of the irregular cross-section receiving sleeve device, it can be used for hoisting operations. In one embodiment, the irregular cross-section receiving sleeve device includes multiple hoisting components 70 fixedly connected to the outer peripheral wall of the cylinder assembly, and each hoisting component 70 is provided with a hoisting hole. The hoisting components 70 are used to connect to a lifting mechanism, such as a chain mechanism, an electric hoist mechanism, or other hoisting mechanisms. The hoisting components 70 are distributed on both sides of the cylinder assembly, allowing the cylinder assembly to be hoisted horizontally, resulting in good hoisting performance.

[0052] For example, two lifting components 70 are welded at intervals on both sides of the cylindrical assembly. The protrusion height of the lifting components 70 exceeds the height of the reinforcing rib 40, and the lifting holes are located outside the protrusion range of the reinforcing rib 40, facilitating the connection of the lifting mechanism. Furthermore, each lifting component 70 is reinforced with lateral connecting ribs to enhance the connection strength with the reinforcing rib 40 and the cylindrical assembly.
