Description

Technical Field

[0001] This application relates to the field of inspection wells, and in particular to a high-strength inspection well ring structure. Background Technology

[0002] In the field of municipal engineering, inspection wells are an important component of urban underground infrastructure, used for inspecting and maintaining underground pipelines and other facilities. The manhole ring, as a key component of the inspection well, bears external forces from road vehicle loads and pedestrian traffic.

[0003] Chinese utility model patent CN202416360U discloses a safety inspection well structure. The well base is covered with a well cover, and a precast concrete well ring is installed on the top of the well barrel. The inner ring of the well barrel and the precast concrete well ring has a well wall. The well base is fixed on the top of the precast concrete well ring by a support. A layer of sand and gravel is laid in the gap between the outer ring of the precast concrete well ring and the well base. A concrete layer and an asphalt layer are laid on the sand and gravel layer from bottom to top. A hook is provided on the inner ring of the precast concrete well ring, and a fall protection net is hung on the hook.

[0004] The aforementioned technologies have the following drawbacks: the well ring is fixed by the support of the sand and gravel layer and the well casing. Since the sand and gravel layer is relatively loose, the well ring is prone to breakage and displacement under repeated vehicle pressure, affecting its use. Utility Model Content

[0005] To improve the strength and stability of the manhole cover, this application provides a high-strength manhole cover structure.

[0006] The high-strength inspection well ring structure provided in this application adopts the following technical solution:

[0007] A high-strength inspection well ring structure, including a well casing;

[0008] A well ring, the bottom of which abuts against the top of the well casing;

[0009] Well seat; the bottom of the well seat abuts against the top of the well ring;

[0010] A connecting mechanism for connecting the well ring and the well base together;

[0011] A concrete layer, which is arranged around the periphery of the well base and the well ring;

[0012] Anchor rods, a plurality of said anchor rods being arranged around the periphery of the well ring, said anchor rods being located within the concrete layer; and...

[0013] The manhole cover has its bottom abutting against the top of the manhole seat.

[0014] By adopting the above technical solution, the bottom of the manhole ring directly abuts against the top of the manhole cylinder, serving as the foundation support. The connecting mechanism connects the manhole ring and the manhole base, making the two form a stable whole. The concrete layer surrounds the manhole base and the manhole ring, filling the gaps between them and the surrounding soil, enhancing the overall structural integrity. The bottom of the manhole cover abuts against the top of the manhole base. The manhole base, as an intermediate transition component, evenly transfers the vehicle load borne by the manhole cover to the manhole ring, and then through the manhole ring and the manhole cylinder to the foundation.

[0015] Preferably, the anchor rod has multiple anti-loosening rods connected sequentially at intervals along its length.

[0016] By adopting the above technical solution, the anti-loosening rod is connected to the anchor rod, which increases the contact area between the anchor rod and the surrounding concrete layer. When the anchor rod is subjected to an external force that causes the well ring to shift, the anti-loosening rod can better grip the surrounding concrete and use the holding force of the concrete to fix the anchor rod more firmly in the concrete layer.

[0017] Preferably, the anti-loosening rod is inclined in the direction away from the well ring.

[0018] By adopting the above technical solution, when the well ring is subjected to an upward or outward external force and tends to be lifted or shifted, the interaction between the inclined anti-loosening rod and the concrete is more effective. The inclined direction of the anti-loosening rod forms a certain angle with the possible displacement direction of the well ring. During the displacement process of the well ring under force, the anti-loosening rod will generate a component force along its inclined direction on the surrounding concrete. This component force will drive the concrete to generate a larger reaction force on the anti-loosening rod. The vertical upward component of this reaction force can effectively resist the upward pull-up force on the well ring. Compared with the horizontally set anti-loosening rod, the inclined setting significantly enhances the pull-out resistance of the anchoring rod system, making the well ring more firmly fixed in place.

[0019] Preferably, the anchor rod is fitted with an anti-loosening spiral ring, and a plurality of anti-loosening rods are sequentially arranged in the gap of the anti-loosening spiral ring along the length direction of the anti-loosening spiral ring.

[0020] By adopting the above technical solution, multiple anti-loosening rods are sequentially installed within the gaps of the anti-loosening spiral ring. They cooperate with the anti-loosening spiral ring to jointly play an anti-loosening role. The anti-loosening rods themselves are inclined away from the well ring. When the well ring has an upward or outward displacement tendency, the anti-loosening rods will generate friction and interlocking force with the concrete. The anti-loosening spiral ring provides a stable support structure for the anti-loosening rods, enabling them to more effectively play their role in resisting displacement. When the well ring is under force, the anti-loosening rods will transfer the force to the anti-loosening spiral ring, which will then distribute the force to the surrounding concrete. This synergistic effect greatly improves the displacement resistance of the anchoring structure.

[0021] Preferably, the connecting mechanism includes a screw and a nut, one end of the screw is connected to the well ring, the other end of the screw passes through the well seat, the nut is threaded onto the screw, and the nut abuts against the top of the well seat.

[0022] By adopting the above technical solution, after the screw passes through the well base, the nut is threaded onto the screw and the screw is tightened. As the nut is tightened, it gradually approaches the top of the well base. Since the nut and the screw are connected by a thread, during the tightening process, the rotational motion of the nut is converted into linear motion along the screw axis. After the nut abuts against the top of the well base, continued tightening will exert downward pressure on the well base. At the same time, the well base will also exert a reaction force on the nut. In this interaction process, the screw will be subjected to tension, which makes the well ring and the well base tightly squeezed together. This squeezing action can effectively eliminate any gaps that may exist between the well ring and the well base, making them fit tightly together and forming a stable connection.

[0023] Preferably, the connecting mechanism further includes an anti-loosening component, which includes an anti-loosening outer toothed ring, an anti-loosening inner toothed ring, and an anti-loosening block. The anti-loosening outer toothed ring is coaxially connected to the nut, the anti-loosening inner toothed ring meshes with the anti-loosening outer toothed ring, and the anti-loosening block is connected to the anti-loosening inner toothed ring. The well seat is provided with an anti-loosening groove, and the anti-loosening block is engaged in the anti-loosening groove.

[0024] By adopting the above technical solution, during the normal use of the inspection well, external forces such as vehicle rolling and ground vibration will affect the connecting mechanism, and the nut will tend to loosen. When the nut attempts to rotate, the anti-loosening outer toothed ring connected to it will also rotate. However, since the anti-loosening outer toothed ring and the anti-loosening inner toothed ring are meshed with each other, the anti-loosening inner toothed ring will prevent the rotation of the anti-loosening outer toothed ring. This is because the anti-loosening block on the anti-loosening inner toothed ring is stuck in the anti-loosening groove of the well seat, and the anti-loosening inner toothed ring cannot rotate freely, thereby restricting the rotation of the anti-loosening outer toothed ring and thus preventing the nut from loosening.

[0025] Preferably, the well ring is provided with a plurality of reinforcing ribs, which are arranged in a ring within the well ring and are connected end to end in sequence.

[0026] By adopting the above technical solutions, the manhole ring needs to withstand pressure from above during use, such as vehicle loads. The reinforcing ribs can increase the thickness and rigidity of the manhole ring. When subjected to external forces, the reinforcing ribs can share part of the load and distribute the force to the entire manhole ring structure, avoiding excessive local stress on the manhole ring and causing deformation or damage, thereby improving the load-bearing capacity of the manhole ring.

[0027] Preferably, an elastic anti-slip layer is connected between the well ring and the well base.

[0028] By adopting the above technical solution, the surface of the elastic anti-slip layer has a certain roughness or special anti-slip texture, which can increase the friction between the well ring and the well seat, preventing relative sliding between the two during use. At the same time, the elastic anti-slip layer can fit tightly between the well ring and the well seat through its own elastic deformation during installation, playing a positioning role, keeping the well ring and the well seat in a relatively fixed positional relationship, and ensuring the stability of the inspection well structure.

[0029] In summary, this application includes the following beneficial technical effects:

[0030] Instead of relying solely on a layer of sand and gravel for support, this method strengthens the connection between the manhole ring and the surrounding structure through a connecting mechanism, a concrete layer, and anchor rods. This effectively resists the external forces generated by repeated vehicle traffic, prevents the manhole ring from shifting, and ensures the normal use of the inspection well.

[0036] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0037] This utility model provides a high-strength inspection well ring structure, the structure of which is as follows: Figure 1 - Figure 3 As shown, it includes a well casing 1, a well ring 2, a well seat 3, a connecting mechanism 4, a concrete layer 5, an anchor rod 6, and a well cover 7.

[0038] The bottom of the well ring 2 abuts against the top of the well casing 1.

[0039] The bottom of the well seat 3 abuts against the top of the well ring 2.

[0040] The connecting mechanism 4 is used to connect the well ring 2 and the well base 3 together.

[0041] A concrete layer 5 is arranged around the well base 3 and the well ring 2.

[0042] Multiple anchor rods 6 are arranged around the well ring 2, and the anchor rods 6 are located inside the concrete layer 5.

[0043] The bottom of the manhole cover 7 abuts against the top of the manhole base 3.

[0044] In use, the bottom of the manhole ring 2 directly abuts against the top of the manhole cylinder 1, serving as a foundation support. The connecting mechanism 4 connects the manhole ring 2 and the manhole base 3, making the two form a stable whole. The concrete layer 5 surrounds the manhole base 3 and the manhole ring 2, filling the gaps between them and the surrounding soil, enhancing the overall structural integrity. The bottom of the manhole cover 7 abuts against the top of the manhole base 3. The manhole base 3, as an intermediate transition component, evenly transfers the vehicle load borne by the manhole cover 7 to the manhole ring 2, and then through the manhole ring 2 and the manhole cylinder 1 to the foundation.

[0045] In this utility model, the traditional method of relying solely on a layer of sand and gravel for support is changed. By using a connecting mechanism 4, a concrete layer 5, and an anchor rod 6, the connection between the manhole ring 2 and the surrounding structure is strengthened, effectively resisting the external force generated by repeated vehicle rolling, preventing the manhole ring 2 from shifting, and ensuring the normal use of the inspection well.

[0046] To ensure a tighter bond between anchor rod 6 and the concrete, please refer to... Figure 1 In a preferred embodiment, a plurality of anti-loosening rods 61 are sequentially and spaced apart along the length of the anchor rod 6.

[0047] When in use, the anti-loosening rod 61 is connected to the anchor rod 6, which increases the contact area between the anchor rod 6 and the surrounding concrete layer 5. When the anchor rod 6 is subjected to an external force that causes the well ring 2 to shift, the anti-loosening rod 61 can better grip the surrounding concrete and use the holding force of the concrete to fix the anchor rod 6 more firmly in the concrete layer 5.

[0048] To further improve the tightness of the bond between anchor rod 6 and the concrete, please refer to... Figure 2 In a preferred embodiment, the anti-loosening rod 61 is inclined in a direction away from the well ring 2.

[0049] When the well ring 2 is subjected to an upward or outward external force and tends to be lifted or shifted, the interaction between the inclined anti-loosening rod 61 and the concrete is more effective. The inclined direction of the anti-loosening rod 61 forms a certain angle with the possible displacement direction of the well ring 2. During the displacement of the well ring 2 under force, the anti-loosening rod 61 will generate a component force along its inclined direction on the surrounding concrete. This component force will drive the concrete to generate a larger reaction force on the anti-loosening rod 61. The vertical upward component of this reaction force can effectively resist the upward pull-up force on the well ring 2. Compared with the horizontally set anti-loosening rod 61, the inclined setting significantly enhances the pull-out resistance of the anchor rod 6 system, making the well ring 2 more firmly fixed in place.

[0050] To further improve the tightness of the bond between anchor rod 6 and the concrete, please refer to... Figure 2 In a preferred embodiment, an anti-loosening spiral ring 62 is fitted on the anchor rod 6, and a plurality of anti-loosening rods 61 are sequentially arranged in the gap of the anti-loosening spiral ring 62 along the length direction of the anti-loosening spiral ring 62.

[0051] In use, multiple anti-loosening rods 61 are sequentially arranged within the gaps of the anti-loosening spiral rings 62. They cooperate with the anti-loosening spiral rings 62 to jointly play an anti-loosening role. The anti-loosening rods 61 are inclined away from the well ring 2. When the well ring 2 has an upward or outward displacement tendency, the anti-loosening rods 61 will generate friction and interlocking force with the concrete. The anti-loosening spiral rings 62 provide a stable support structure for the anti-loosening rods 61, enabling the anti-loosening rods 61 to more effectively play their role in resisting displacement. When the well ring 2 is under force, the anti-loosening rods 61 will transfer the force to the anti-loosening spiral rings 62, and the anti-loosening spiral rings 62 will then distribute the force to the surrounding concrete. This synergistic effect greatly improves the displacement resistance of the anchoring structure.

[0052] To connect well ring 2 and well base 3 together, please refer to... Figure 2 In a preferred embodiment, the connecting mechanism 4 includes a screw 41 and a nut 42. One end of the screw 41 is connected to the well ring 2, and the other end of the screw 41 passes through the well seat 3. The nut 42 is threaded onto the screw 41 and abuts against the top of the well seat 3.

[0053] In use, after the screw 41 passes through the well seat 3, the nut 42 is threaded onto the screw 41, and the screw 42 is tightened. As the nut 42 is tightened, it gradually approaches the top of the well seat 3. Since the nut 42 and the screw 41 are threaded, during the tightening process, the rotational motion of the nut 42 is converted into linear motion along the axis of the screw 41. After the nut 42 comes to abut against the top of the well seat 3, the continued tightening will exert downward pressure on the well seat 3. At the same time, the well seat 3 will also exert a reaction force on the nut 42. In this interaction process, the screw 41 will be subjected to tension, which will cause the well ring 2 and the well seat 3 to be tightly squeezed together. This squeezing action can effectively eliminate any gaps that may exist between the well ring 2 and the well seat 3, so that the two fit tightly together and form a stable connection.

[0054] To reduce the possibility of nut 42 loosening, please refer to Figure 2 In a preferred embodiment, the connecting mechanism 4 further includes an anti-loosening component 8, which includes an anti-loosening outer toothed ring 81, an anti-loosening inner toothed ring 82, and an anti-loosening block 83. The anti-loosening outer toothed ring 81 is coaxially connected to the nut 42, the anti-loosening inner toothed ring 82 meshes with the anti-loosening outer toothed ring 81, and the anti-loosening block 83 is connected to the anti-loosening inner toothed ring 82. The well base 3 is provided with an anti-loosening groove 84, and the anti-loosening block 83 is engaged in the anti-loosening groove 84.

[0055] During normal use of the inspection well, external forces such as vehicle rolling and ground vibration will affect the connecting mechanism 4, causing the nut 42 to loosen. When the nut 42 attempts to rotate, the anti-loosening outer toothed ring 81, which is coaxially connected to it, will also rotate. However, since the anti-loosening outer toothed ring 81 and the anti-loosening inner toothed ring 82 are meshed with each other, the anti-loosening inner toothed ring 82 will prevent the rotation of the anti-loosening outer toothed ring 81. This is because the anti-loosening block 83 on the anti-loosening inner toothed ring 82 is engaged in the anti-loosening groove 84 of the well seat 3, and the anti-loosening inner toothed ring 82 cannot rotate freely, thus restricting the rotation of the anti-loosening outer toothed ring 81, and thus preventing the nut 42 from loosening.

[0056] To improve the overall strength of well ring 2, please refer to Figure 3 In a preferred embodiment, the well ring 2 is provided with a plurality of reinforcing ribs 21, which are arranged in a ring around the well ring 2 and are connected end to end in sequence.

[0057] When in use, the manhole ring 2 needs to withstand pressure from above, such as vehicle loads. The reinforcing rib 21 can increase the thickness and rigidity of the manhole ring 2. When subjected to external forces, the reinforcing rib 21 can share part of the load and distribute the force to the entire structure of the manhole ring 2, preventing the manhole ring 2 from being deformed or damaged due to excessive local stress, thereby improving the load-bearing capacity of the manhole ring 2.

[0058] To improve the overall strength of well ring 2 and well base 3, please refer to Figure 1In a preferred embodiment, an elastic anti-slip layer 22 is connected between the well ring 2 and the well base 3.

[0059] When in use, the surface of the elastic anti-slip layer 22 has a certain roughness or special anti-slip texture, which can increase the friction between the well ring 2 and the well base 3 and prevent them from sliding relative to each other during use. At the same time, when installed, the elastic anti-slip layer 22 can fit tightly between the well ring 2 and the well base 3 through its own elastic deformation, which plays a positioning role and keeps the well ring 2 and the well base 3 in a relatively fixed positional relationship, ensuring the stability of the inspection well structure.

[0060] The implementation principle of a high-strength manhole ring structure in this application embodiment is as follows: the bottom of the manhole ring 2 directly abuts against the top of the manhole cylinder 1, serving as a foundation support. The connecting mechanism 4 connects the manhole ring 2 and the manhole base 3, making the two form a stable whole. The concrete layer 5 surrounds the manhole base 3 and the manhole ring 2, filling the gaps between them and the surrounding soil, enhancing the overall structural integrity. The bottom of the manhole cover 7 abuts against the top of the manhole base 3. The manhole base 3 serves as an intermediate transition component, evenly transferring the vehicle load borne by the manhole cover 7 to the manhole ring 2, and then through the manhole ring 2 and the manhole cylinder 1 to the foundation.

[0061] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
