Abstract

This invention patent relates to the technical field of drainage blind ditches, specifically to an integral double-ring self-pollution-discharging heavy-load slag yard blind ditch, which includes a protective grille, a filament geotextile, a discharge pipe body, longitudinal nylon nails, a support plate, a support ring and an auxiliary support inner arm, and the support ring is arranged inside the discharge pipe body. In this invention, the original cross-shaped support frame arranged inside the existing discharge pipe body is set in the form of connection and support between the support ring and the support plate. Through the support ring and the support plate, it can not only play a role in supporting the inside of the discharge pipe body, but also there will be no narrow dead corners between the support ring and the support plate, so that the fine sand and gravel falling on the support ring and the support plate will not accumulate and pile up, enabling the discharge pipe body to drain water stably for a long time without clogging.

Description

Technical Field

[0001] The present invention relates to the technical field of drainage blind ditches, specifically an integral double-ring self-sewage-discharging heavy-load slag yard blind ditch. Background Art

[0002] The drainage blind ditch of the slag yard is an underground drainage facility designed to ensure smooth drainage of the slag yard. The drainage blind ditch of the slag yard is a blind ditch arranged in the roadbed or foundation for drainage and water interception. It is mainly filled with coarse-grained materials (such as crushed stones, gravels, etc.), and may be paved with an inverted filter layer or buried with a permeable pipe. The main function of the blind ditch is to drain groundwater and lower the groundwater level to prevent the adverse effects of groundwater on the slag yard. The existing high-strength underground drainage pipes (main pipes and branch pipes) have a portal arch cross-section structure with a circular upper part and a rectangular lower part tangent to each other, and are internally designed with a "*"-shaped strengthening support (as Figure 6 shown). Since the "*"-shaped strengthening support arranged inside is prone to accumulate and adhere to fine sand and gravel in the drainage at the included angle during use, blockage is caused over time, and the sand and gravel at the included angle of the "*"-shaped strengthening support member are not easy to clean and drain away, resulting in poor drainage effect. In addition, the positions on both sides of the bottom of the existing pipe body are prone to be bent by external pressure during the laying and use process, thus affecting the long-term stable use of the pipe body and being inconvenient for stable laying and use. Therefore, a device is needed to solve the above-mentioned problems. Summary of the Invention

[0003] In view of the problems in the prior art, the present invention provides an integral double-ring self-sewage-discharging heavy-load slag yard blind ditch.

[0004] The technical solution adopted by the present invention to solve its technical problems is: an integral double-ring self-sewage-discharging heavy-load slag yard blind ditch, including a protective grille, a filament geotextile, a discharge pipe body, longitudinal nylon nails, a support plate, a support ring and an auxiliary support inner arm. The support ring is arranged inside the discharge pipe body. The support plates are evenly and fixedly connected between the support ring and the inner wall of the discharge pipe body. The auxiliary support inner arms are fixedly connected between the bottoms of the support plates located on both sides below and the bottom inner wall of the discharge pipe body. The filament geotextile and the protective grille are fixed to the outside of the discharge pipe body through longitudinal nylon nails. The protective grille is located outside the filament geotextile. Permeable holes with a diameter of 6 mm - 8 mm are provided at two-thirds of the upper part of the discharge pipe body for guiding the groundwater absorbed by the water-absorbing material into the pipe body. The longitudinal hole pitch is 45 mm, and the circumferential hole pitch is 35 mm.

[0005] Specifically, the ends of the discharge pipe body are connected by a flexible connector. Connection compensation rings are fixedly connected to both ends of the flexible connector. The connection compensation rings are closely attached to the outside of the protective grille. End face gaskets are arranged inside both ends of the flexible connector, and the ends of the discharge pipe body are in extrusion contact with the end face gaskets. Reinforcing load-bearing rings are evenly arranged on the flexible connector. Both ends of the flexible connector are fixedly connected to the discharge pipe body through PVC connection sleeves and nylon screws.

[0006] Specifically, a rigid four-way joint is arranged between the ends of the discharge pipe body.

[0007] Specifically, the flexible connector is made of vulcanized rubber, the PVC connection sleeve is made of PVC resin. The maximum longitudinal expansion amount of the flexible connector is 20 mm, and the maximum radial deformation amount is 12 mm. The discharge pipe body is a PVC pipe.

[0008] Specifically, side reinforcement connecting plates are fixedly connected to both sides of the bottom end of the discharge pipe body.

[0009] Specifically, auxiliary reinforcement bodies are evenly arranged on the discharge pipe body.

[0010] Specifically, the auxiliary reinforcement body includes a first reinforcement part and a second reinforcement part. The first reinforcement part and the second reinforcement part are mirror-symmetrically distributed, and the first reinforcement part and the second reinforcement part have the same structure.

[0011] Advantages of the present invention:

[0012] First, in the present invention, the original cross-shaped support frame arranged inside the discharge pipe body is set in the form of a support ring and a support plate connected for support. Through the support ring and the support plate, it can play a role in supporting the inside of the discharge pipe body, and there will be no narrow dead corners between the support ring and the support plate. Fine sand and gravel falling on the support ring and the support plate will not accumulate, so that the discharge pipe body can drain water stably for a long time without being blocked. In addition, the auxiliary support inner arms arranged on both sides inside the discharge pipe body play a role in reinforcement and support, so that the discharge pipe body will not be bent during use.

[0013] Second, in the present invention, the side reinforcement connecting plates arranged at the bottom of both sides of the discharge pipe body play a role in reinforcing and supporting the bottom of the discharge pipe body, so that the discharge pipe body can be used stably for a long time and is not easily bent at the bottom. The arranged auxiliary reinforcement body can enable the discharge pipe body to be laid stably and used continuously and stably for a long time. And because the overall contact area of the auxiliary reinforcement body with the discharge pipe body is small and it is distributed at a specified interval, while being able to play a role in reinforcement, it will not affect the normal drainage of the discharge pipe body.

Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] Embodiment 1, as Figures 1-5 shown, the integral double-ring self-sewage heavy-duty slag yard blind ditch of the present invention includes a protective grille 7, a filament geotextile 8, a discharge pipe body 9, longitudinal nylon nails 10, a support plate 11, a support ring 12, and an auxiliary support inner arm 13. The support ring 12 is arranged inside the discharge pipe body 9. The support plates 11 are evenly fixedly connected between the support ring 12 and the inner wall of the discharge pipe body 9. The auxiliary support inner arms 13 are fixedly connected between the bottoms of the support plates 11 on both sides below and the bottom inner wall of the discharge pipe body 9. The filament geotextile 8 and the protective grille 7 are fixed to the outside of the discharge pipe body 9 through longitudinal nylon nails 10. The protective grille 7 is located outside the filament geotextile 8. The upper two-thirds position of the discharge pipe body 9 is provided with water-permeable holes with a diameter of 6 mm - 8 mm for guiding the groundwater absorbed by the water-absorbing material into the pipe body. The longitudinal hole pitch is 45 mm, and the circumferential hole pitch is 35 mm. Through the support ring 12 and the support plates 11, it can play a role in supporting the inside of the discharge pipe body 9, and there will be no narrow dead corners between the support ring 12 and the support plates 11, so that the fine sand and gravel falling on the support ring 12 and the support plates 11 will not accumulate and accumulate, enabling the discharge pipe body 9 to drain stably for a long time. And the two sides inside the discharge pipe body 9 play a role of reinforcement and support through the provided auxiliary support inner arms 13, so that the discharge pipe body 9 will not be bent during use. The provided protective grille 7 and filament geotextile 8 play a role of blocking and filtering.

[0030] The ends of the discharge pipe body 9 are connected through a flexible connector 4. The two ends of the flexible connector 4 are fixedly connected with connection compensation rings 6. The connection compensation rings 6 are closely attached to the outside of the protective grille 7. End face gaskets 2 are arranged inside the two ends of the flexible connector 4, and the ends of the discharge pipe body 9 are in pressing contact with the end face gaskets 2. Reinforcing load-bearing rings 3 are evenly arranged on the flexible connector 4. The two ends of the flexible connector 4 are fixedly connected with the discharge pipe body 9 through PVC connection sleeves 5 and nylon screws 1. The provided end face gaskets 2 play a role of sealing connection. The provided nylon screws 1 and connection compensation rings 6 can achieve firm and convenient connection. The provided reinforcing load-bearing rings 3 play a role of reinforcement.

[0031] A rigid four-way joint 41 is provided between the ends of the discharge pipe body 9. The flexible connector 4 is made of vulcanized rubber, and the PVC connecting ferrule 5 is made of PVC resin. The maximum longitudinal expansion of the flexible connector 4 is 20 mm, and the maximum radial deformation is 12 mm. The discharge pipe body 9 is a PVC pipe.

[0032] The working principle of Embodiment 1 is as follows: By setting the cross-shaped support frame inside the existing discharge pipe body 9 in the form of a support ring 12 and a support plate 11 connected for support, the support ring 12 and the support plate 11 can not only play a role in supporting the inside of the discharge pipe body 9, but also there will be no narrow dead corners between the support ring 12 and the support plate 11, so that the fine sand and gravel falling on the support ring 12 and the support plate 11 will not accumulate, enabling the discharge pipe body 9 to drain water stably for a long time. In addition, the two sides inside the discharge pipe body 9 are reinforced by the auxiliary support inner arms 13 provided, so that the discharge pipe body 9 will not be bent during use.

[0033] The flexible connector 4 provided facilitates the bending connection of the discharge pipe body 9 and is convenient for laying and use. The rigid four-way joint 41 provided facilitates the connection and use of the discharge pipe body 9 and the branch pipes. The provided protective grille 7 is used to prevent the backfill from piercing the filament geotextile 8. The thickness of the protective grille 7 is not less than 4.5 mm; the aperture on the protective grille 7 is not larger than 5 mm × 5 mm. The end of each main pipe or branch pipe is blocked with a special plug to prevent soil particles or sundries from entering the inside of the drainage system and causing blockage of the drainage system. During the laying process, the slope change point at the bottom of the trench should be set at the connection of two pipes. At this time, the main pipes and the main pipes, and the branch pipes and the branch pipes are connected with special joints of the flexible connector 4 to meet the need of slope change. The branch pipe and the main pipe are connected with a rigid four-way joint 41. The rigid four-way joint 41 is used to connect the 300-type main pipe and the 100-type branch pipe.

[0034] Embodiment 2, on the basis of Embodiment 1, as Figures 7-11 shown, both sides of the bottom end of the discharge pipe body 9 are fixedly connected with side reinforcement connecting plates 14. The discharge pipe body 9 is evenly provided with auxiliary reinforcement main bodies 15. The auxiliary reinforcement main body 15 includes a first reinforcement part 16 and a second reinforcement part 17. The first reinforcement part 16 and the second reinforcement part 17 are mirror-symmetrically distributed, and the first reinforcement part 16 and the second reinforcement part 17 have the same structure.

[0035] Both the first reinforcement part 16 and the second reinforcement part 17 include a fixed installation base 18, a limit partition board 19, fixed threaded holes 20, support springs 21, locking fixed bolts 22, pressing control handles 23, L-shaped connecting plates 24, lifting and adjusting support frames 25, pressing cross plates 27, arc pressing plates 28, extrusion locking threaded columns 30, sliding locking cards 31, limit frames 32 and side extrusion support plates 33. The fixed installation base 18 is fixedly connected to the bottom end of the limit frame 32, the side extrusion support plate 33 is fixedly connected to the side end of the limit frame 32, the lifting and adjusting support frame 25 is slidably clamped inside the limit frame 32, the extrusion locking threaded columns 30 are symmetrically threaded and rotatably inserted inside the limit frame 32, and the front ends of the extrusion locking threaded columns 30 are in extrusion contact with the outer wall of the lifting and adjusting support frame 25. The pressing cross plate 27 is fixedly connected to the upper end of the lifting and adjusting support frame 25, the arc pressing plate 28 is fixedly connected to the bottom end of the head of the pressing cross plate 27 by bolts. The limit partition board 19 is fixedly connected to the bottom of the outer side end of the limit frame 32, the fixed threaded holes 20 are symmetrically opened at the bottom of the limit frame 32, and the fixed threaded holes 20 are located above the limit partition board 19. The sliding locking card 31 is slidably clamped on the limit frame 32, the L-shaped connecting plate 24 is fixedly connected to the outer side end of the sliding locking card 31, the locking fixed bolts 22 are symmetrically threaded and rotatably inserted at the bottom of the L-shaped connecting plate 24. The support springs 21 are symmetrically clamped inside the limit frame 32, and the top ends of the support springs 21 are located at the bottom of the sliding locking card 31. An extrusion adjusting threaded rod 26 is threaded and inserted through the pressing cross plate 27, and a pressing limit wheel 29 is rotatably installed at the bottom end of the extrusion adjusting threaded rod 26 through a mounting frame. The inner side ends of the limit frame 32 and the side extrusion support plate 33 are in fit with the outer bottom end face of the discharge pipe body 9, and the bottom end of the sliding locking card 31 is adapted to the card slot arranged at the upper end of the side reinforcement connecting plate 14.

[0036] When implementing this embodiment, the side reinforcement connecting plates 14 arranged at the two bottom sides of the discharge pipe body 9 play a role in reinforcing and supporting the bottom of the discharge pipe body 9, enabling the discharge pipe body 9 to be stably used for a long time and not easily bent at the bottom. By providing the auxiliary reinforcement main body 15, the discharge pipe body 9 can be stably laid and continuously and stably used for a long time;

[0037] After the position where the discharge pipe body 9 is laid is driven, the first reinforcement part 16 and the second reinforcement part 17 in the auxiliary reinforcement main body 15 are laid on both sides of the discharge pipe body 9, so that the fixed installation bases 18 arranged at the bottoms of the first reinforcement part 16 and the second reinforcement part 17 are fixed on both sides of the discharge pipe body 9. At this time, the limit frame 32 and the side extrusion support plate 33 are in extrusion fit with the outer bottom end of the discharge pipe body 9 for support and reinforcement. Then, press the lifting and adjusting support frame 25 and the pressing cross plate 27, so that the pressing cross plate 27 and the arc pressing plate 28 in the first reinforcement part 16 and the second reinforcement part 17 move downward synchronously, so that the arc pressing plates 28 in the first reinforcement part 16 and the second reinforcement part 17 are spliced to adapt to extrude and limit the filament geotextile 8 and the protection grille 7 arranged outside the discharge pipe body 9. Then, lock and fix the lifting and adjusting support frame 25 and the limit frame 32 by screwing the extrusion and locking threaded column 30. And at this time, press the pressing control handle 23 downward by an external force to drive the L-shaped connecting plate 24 to drive the sliding locking card plate 31 to move downward. At this time, the sliding locking card plate 31 slides downward along the limit frame 32 and compresses the support spring 21, so that the bottom end of the L-shaped connecting plate 24 contacts the limit partition plate 19. Then, screw the locking and fixing bolt 22. At this time, the locking and fixing bolt 22 is screwed into the internal fixed threaded hole 20, so that the L-shaped connecting plate 24 and the sliding locking card plate 31 are limited and fixed. And at this time, the bottom end of the downward-moving sliding locking card plate 31 slides and inserts into the clamping groove arranged at the upper end of the side reinforcement connecting plate 14 to achieve locking and fixing, which can stably limit and fix the bottom side end of the discharge pipe body 9. And because the overall contact area between the auxiliary reinforcement main body 15 and the discharge pipe body 9 is small and is distributed at a specified interval, while being able to play a role in reinforcement, it will not affect the normal drainage of the discharge pipe body 9.

[0038] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
