Description

Technical Field

[0001] This utility model belongs to the field of water conveyance underground channel technology, and in particular relates to a spliced ​​prefabricated underground channel cover. Background Technology

[0002] A culvert is an artificial waterway buried underground with a closed or semi-closed structure. It is typically constructed of concrete, brick, reinforced concrete, or precast pipes, and its core function is to conceal the flow of water. In use, culverts can efficiently collect and drain water without occupying surface space. Simultaneously, their closed structure effectively prevents the emission of odors from sewage, improving environmental sanitation and the aesthetics of the city.

[0003] A culvert cover is a component that covers the opening at the top of a culvert, used to bear the loads of vehicles and pedestrians above, while protecting the culvert structure below. In existing technology, culvert covers are usually prefabricated components, requiring workers to lay them one by one on top of the culvert during construction. However, the splicing of existing culvert covers is not convenient, making construction difficult. After installation, the lack of effective connections between multiple culvert covers makes it easy for individual covers to shift under load, affecting the flatness of the culvert surface. Utility Model Content

[0004] In view of this, the present invention aims to propose a spliced ​​prefabricated culvert cover to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A prefabricated interlocking culvert cover includes: a cover body, a movable plate, and a connecting assembly; the top surface of the cover body has a receiving groove, and the bottom surface of the receiving groove has a partition strip, the length direction of the partition strip being parallel to the length direction of the cover body; both sides of the partition strip have accumulation grooves, and the side wall of the partition strip has a guide hole communicating with the outside; both ends of the top of the partition strip have support blocks, and the opposite side walls of the two support blocks have splicing slots; the inner side wall of the splicing slot has a group of connecting holes, the group of connecting holes including multiple connecting holes, and the axial direction of any one of the connecting holes is parallel to the length direction of the partition strip; the movable plate is detachably mounted on the top of the receiving groove, and the bottom surface of the movable plate is in contact with the top surface of the support block; the connecting assembly includes a pull rod group and a splicing plug, the pull rod group including multiple pull rods, and the multiple pull rods are placed one-to-one inside the multiple connecting holes; the splicing plug is placed inside the splicing slot, and the splicing plug is detachably connected to the end of the pull rod.

[0007] Furthermore, the end of the pull rod is provided with a threaded rod, and the splice plug is provided with an assembly hole for accommodating the threaded rod; the threaded rod is also provided with a locking nut, and the locking nut is located on the side of the splice plug away from the pull rod.

[0008] Furthermore, the end of the connector away from the pull rod is provided with a limiting ring, and the outer diameter of the limiting ring is larger than the inner diameter of the connector slot.

[0009] Furthermore, the outer wall of the connector is provided with a rubber coating.

[0010] Furthermore, the partition bar has a guide slope on the side near the storage tank, and the flow guide hole is set on the guide slope; a flow guide groove is provided on the bottom surface of the cover plate body, the flow guide groove is located below the partition bar, and the flow guide hole is connected to the flow guide groove.

[0011] Furthermore, the bottom surface of the storage tank is provided with a drain hole, and the diameter of the drain hole is smaller than the diameter of the guide hole.

[0012] Furthermore, the movable plate is provided with multiple drainage cuts.

[0015] Compared with existing technologies, the splicing prefabricated culvert cover of this utility model has the following advantages:

[0016] (1) The prefabricated interlocking culvert cover of this utility model can effectively connect two adjacent cover bodies through connecting components, thereby improving the correlation between adjacent culvert covers, preventing a culvert cover from shifting when subjected to instantaneous loads, and ensuring good flatness above the culvert. In addition, the connecting components in this device include multiple tie rods, and the bearing block is provided with a splicing slot for accommodating splicing plugs. When a culvert cover tends to deflect or vibrate due to the load above, the cooperation of multiple tie rods and multiple connecting holes, as well as the cooperation of splicing plugs and splicing slots, can improve the overall integrity between multiple culvert covers, thereby improving the stability of the culvert cover.

[0030] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] A type of modular prefabricated culvert cover, the structure of which can be made of Figures 1-6 The following is an illustration. In this embodiment, the spliced ​​prefabricated culvert cover includes: a cover body 1, a movable plate 2, and a connecting component. The cover body 1 is used to cover the top of the culvert, the movable plate 2 is used to make the top surface of the cover body 1 a flat surface that facilitates passage, and the connecting component is used to improve the connection effect between two adjacent culvert covers and prevent one of the culvert covers from shifting when bearing a load.

[0032] Specifically, the top surface of the cover plate body 1 is provided with a receiving groove, and the bottom surface of the receiving groove is provided with a dividing strip 11 whose length direction is parallel to the length direction of the cover plate body 1. On both sides of the dividing strip 11, there are accumulation grooves 12, and on the side wall of the dividing strip 11, there are guide holes 13 communicating with the outside. During use, the liquid to be collected (e.g., rainwater) above the culvert cover plate will enter the receiving groove. Because the receiving groove is divided into two accumulation grooves 12 by the dividing strip 11, and the side wall of the accumulation groove 12 is provided with guide holes 13 communicating with the outside, solid substances mixed in with the liquid will be intercepted in the accumulation grooves 12, while the liquid portion will pass through the guide holes 13 and eventually converge into the culvert.

[0033] Optionally, to improve the liquid guiding efficiency of this device, a drain hole 121 with a diameter smaller than that of the guiding hole 13 may be provided on the bottom surface of the storage tank 12, thereby improving the efficiency of liquid leaving the storage tank 12 by means of the drain hole 121.

[0034] In addition, such as Figure 3 and Figure 5 As shown, in this embodiment, a guide slope 111 may be provided on the side of the separator 11 near the storage tank 12, and a flow guide hole 13 is provided on the guide slope 111. Simultaneously, a flow guide groove 15 should be provided on the bottom surface of the cover plate body 1, located below the separator 11, and the flow guide hole 13 should be connected to the flow guide groove 15. Since the flow guide hole 13 is provided on the guide slope 111, when solid material is intercepted inside the storage tank 12, the inclination of the guide slope 111 reduces the probability of the flow guide hole 13 becoming blocked, thereby extending the cleaning and maintenance cycle of this device.

[0035] To facilitate the assembly between the movable plate 2 and the cover plate body 1, support blocks 14 are provided at both ends of the top of the partition strip 11. During assembly, the operator can detachably place the movable plate 2 on the top of the receiving groove and make the bottom surface of the movable plate 2 contact the top surface of the support block 14, thereby using the support block 14 to support the movable plate 2 and prevent the movable plate 2 from shaking when bearing the load.

[0036] Optionally, in this embodiment, the movable plate 2 may be provided with mounting holes, and mounting bolts 22 may be provided inside the mounting holes. Correspondingly, the top surface of the support block 14 should be provided with mounting screw holes 143 for accommodating the mounting bolts 22, so that the movable plate 2 can be reliably installed on the cover plate body 1 by means of the mounting bolts 22 and the mounting screw holes 143.

[0037] In practical applications, culvert covers can be broadly classified into two types: permeable and closed. When liquid collection is required, a permeable culvert cover should be selected to allow liquid to enter the culvert. When it is necessary to prevent contamination of the liquid inside the culvert, a closed culvert cover should be selected to prevent contaminants from entering the culvert. To meet these usage requirements, the movable plate 2 in this embodiment can also be divided into permeable and closed types, such as... Figure 2 As shown, the permeable movable plate 2 should have multiple drainage cuts 21, while the closed movable plate 2 should not have drainage cuts 21. During use, operators can install the corresponding type of movable plate 2 onto the cover plate body 1 according to the actual situation, thereby meeting different usage requirements.

[0038] Figure 6 The exploded view of the connecting assembly in this embodiment shows that the connecting assembly includes a pull rod assembly and a connector 4. The pull rod assembly includes multiple pull rods 3, and the connector 4 is detachably connected to the end of the pull rod 3. Accordingly, to achieve the assembly between the connecting assembly and the cover plate body 1, as shown... Figure 5 As shown, each of the two supporting blocks 14 has a splicing slot 141 on its opposite sidewall. The inner sidewall of the splicing slot 141 has a group of connecting holes, which should include multiple connecting holes 142, with the axis of any one of the connecting holes 142 parallel to the length direction of the partition strip 11. During assembly, multiple pull rods 3 are placed one-to-one inside the multiple connecting holes 142, and the splicing plug 4 should be placed inside the splicing slot 141. When multiple culvert covers are laid simultaneously on top of the culvert, the connecting assembly enables an effective connection between adjacent culvert covers, thereby improving the overall integrity of the multiple culvert covers. When a culvert cover shifts, deflects, or vibrates due to load, the connecting assembly can transmit the tendency of the load to other adjacent culvert covers, ensuring good stability for the multiple culvert covers above the culvert.

[0039] To achieve a detachable connection between the connector 4 and the pull rod 3, the end of the pull rod 3 may be provided with a threaded rod 31, and the connector 4 may be provided with an assembly hole 41 for accommodating the threaded rod 31. A locking nut 32 may also be provided on the threaded rod 31. After the threaded rod 31 passes through the assembly hole 41, the operator should install the locking nut 32 on the side of the connector 4 away from the pull rod 3, and then tighten the locking nut 32 to reliably insert the connector 4 into the connector slot 141.

[0040] Optionally, to prevent the connector 4 from shaking inside the slot 141 due to load transmission, a rubber coating can be provided on the outer wall of the connector 4. The rubber coating increases the frictional resistance between the connector 4 and the slot 141, preventing abnormal sliding of the connector 4. It also seals the gaps between the connector 4 and the slot 141, ensuring that the connector 4 is securely inserted into the slot 141.

[0041] In addition, in this embodiment, a limiting retaining ring 42 with an outer diameter larger than the inner diameter of the splicing slot 141 can be provided at the end of the splicing plug 4 away from the pull rod 3. When the locking nut 32 is tightened, the limiting retaining ring 42 will fit tightly against the side wall of the support block 14 where the splicing slot 141 is provided, further improving the assembly reliability between the connecting component and the cover plate body 1.

[0042] As an optional implementation of this embodiment, to improve the connection reliability between the culvert cover and the culvert body, a support strip 16 can be provided on the side wall of the cover body 1, and an anchor hole 161 is provided on the support strip 16. After the worker lays the device on the culvert body, anchors can be driven into the anchor holes 161 (the anchors can be driven into the culvert body or into the ground near the culvert body), thereby improving the reliability of the culvert cover with the help of the anchors.

[0043] The effects of the above solution are explained below:

[0044] This embodiment provides a modular prefabricated culvert cover that effectively connects adjacent cover bodies through connecting components, thereby improving the interrelationship between adjacent culvert covers. Secondly, this device enables load transfer between adjacent culvert covers through the connecting components, thus improving the stability and integrity of the culvert covers. Furthermore, this device can effectively guide liquids, facilitating their convergence into the culvert and intercepting solid impurities in the liquid within the accumulation tank, while effectively reducing the frequency of cleaning and maintenance of the culvert covers.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
