DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figure 1-Figure 10 As shown, a reinforced double-wall corrugated pipe capable of preventing falling off comprises: a reinforced double-wall corrugated pipe 1, a bottom plate 2 and a steel wire rope 14,

[0035] The enhanced double-wall corrugated pipe 1 is provided with two groups, and the two groups of enhanced double-wall corrugated pipes 1 are mutually abutted and connected. The upper and lower ends of the enhanced double-wall corrugated pipe 1 are respectively sleeved and connected with sleeves 5, and the inner wall of the sleeve 5 is wavy. When the two groups of enhanced double-wall corrugated pipes 1 are installed, one group of sleeves 5 is placed on the ground, and the two groups of enhanced double-wall corrugated pipes 1 are placed on the inner wall of the sleeve 5 to abut against each other, and the other group of sleeves 5 is placed on the top of the enhanced double-wall corrugated pipe 1. The two groups of sleeves 5 abut against each other, and the shape of the inner wall of the sleeve 5 can abut and limit the two groups of enhanced double-wall corrugated pipes 1 to avoid the loosening of the enhanced double-wall corrugated pipe 1. When the enhanced double-wall corrugated pipe 1 is crushed by a vehicle or hit by a heavy object, the sleeve 5 can block the sudden external force generated thereon to avoid the external force from affecting the two groups of enhanced double-wall corrugated pipes 1, thereby avoiding the phenomenon that the enhanced double-wall corrugated pipe 1 falls off after installation;

[0036] The bottom plate 2 is provided with two groups and is respectively fixedly connected to the two ends of the sleeve 5. The top of the bottom plate 2 is abutted and connected with the top plate 3. The top plate 3 is provided with two groups and is respectively fixedly connected to the two ends of the sleeve 5. When the two groups of sleeves 5 are combined together, the top plates 3 fixed at the two ends of the top sleeve 5 and the bottom plates 2 fixed at the two ends of the bottom sleeve 5 are abutted together. The abutment between the bottom plate 2 and the top plate 3 can prevent debris from entering the sleeve 5.

[0037] Several groups of steel wire ropes 14 are provided along the length direction of the casing 5 and are linear. The steel wire ropes 14 are abutted and connected with the casing 5. The steel wire ropes 14 are fixedly connected with a locking assembly. Workers bundle several steel wire ropes 14 on the outer wall of the casing 5 in sequence. The steel wire ropes 14 fix the two groups of casings 5 ​​together by abutting against the outer wall of the casing 5, thereby fixing the bottom plate 2 and the top plate 3 together. The workers lock and fix the steel wire ropes 14 with the locking assembly, thereby achieving the effect of fixing the steel wire ropes 14 and the outer wall of the casing 5.

[0038] In some specific embodiments, a sealing groove 12 is provided at the top of the bottom plate 2 along the length direction, a locking hole 13 is provided inside the bottom plate 2 through the top plate 3, a sealing plate 11 is abutted and connected to the inner wall of the sealing groove 12, the inner wall of the locking hole 13 is abutted and connected to the steel wire rope 14, and the sealing plate 11 is fixedly connected to the bottom end of the top plate 3. When the sleeve 5 placed on the top of the reinforced double-wall corrugated pipe 1 is installed, the worker first fills the sealing groove 12 with glue, and then embeds the sealing plate 11 fixed to the top plate 3 into the sealing groove 12, and the sealing plate 11 and the sealing plate 11 are fixedly connected to the bottom end of the top plate 3. The inner wall of the sealing groove 12 is abutted, and the sealing plate 11 realizes the sealing between the bottom plate 2 and the top plate 3, further preventing debris from entering the sleeve 5 through the gap between the bottom plate 2 and the top plate 3. The glue can firmly fix the sealing plate 11 in the sealing groove 12. When the top plate 3 is installed on the bottom plate 2, the worker passes the wire rope 14 through the locking hole 13. The wire rope 14 is abutted against the inner wall of the locking hole 13, further abutting and fixing the bottom plate 2 and the top plate 3, thereby ensuring the stability of the bottom plate 2 and the top plate 3 abutting against each other.

[0039] In some specific embodiments, a buffer assembly is fixedly connected to the top of the top plate 3, and the buffer assembly is located on the top of the sleeve 5. A plurality of supporting feet 4 are fixedly connected to the bottom end of the bottom plate 2 along the length direction. When the sleeve 5 placed at the bottom of the enhanced double-wall corrugated pipe 1 is installed, the supporting feet 4 fixed at the bottom end of the bottom plate 2 abut against the ground. The abutment between the supporting feet 4 and the ground provides support for the bottom plate 2, thereby ensuring the stability of the sleeve 5 when placed at the bottom of the enhanced double-wall corrugated pipe 1 and avoiding the sleeve 5 from rotating. At the same time, when workers place the enhanced double-wall corrugated pipe 1, the sleeve 5 will not be offset, thereby facilitating the workers to place the enhanced double-wall corrugated pipe 1. When the enhanced double-wall corrugated pipe 1 is crushed by a vehicle or hit by a heavy object, the buffer assembly can buffer the external force to further reduce the effect of the external force on the enhanced double-wall corrugated pipe 1.

[0040] In some specific embodiments, the buffer assembly includes: a buffer plate 7, a buffer column 8, a buffer tube 9 and a spring 10. The buffer column 8 and the buffer tube 9 are equidistantly arranged in several groups along the length direction of the top plate 3 and are respectively located on both sides of the sleeve 5. The top of the buffer column 8 is fixedly connected to the buffer plate 7, the buffer column 8 is slidably connected to the inner wall of the buffer tube 9, the bottom of the buffer tube 9 is fixedly connected to the top plate 3, and the spring 10 is arranged in the buffer tube 9 and the upper and lower ends are respectively fixedly connected to the buffer column 8 and the top plate 3. When the buffer assembly is running, the external force is transmitted to the buffer plate 7 through the soil, the buffer plate 7 drives the buffer column 8 to move downward, and the buffer column 8 slides downward along the inner wall of the buffer tube 9. The buffer column 8 converts the external force into the compression elastic force of the spring 10 by compressing the spring 10, thereby achieving the effect of buffering the external force. The distribution of the buffer column 8 and the buffer tube 9 can ensure that the buffer plate 7 is evenly subjected to the elastic force of the spring 10, and the abutment between the buffer column 8 and the inner wall of the buffer tube 9 can provide a limiting effect for the buffer plate 7 to prevent the buffer plate 7 from overturning.

[0041] In some specific implementation schemes, the two ends of the buffer plate 7 are respectively fixedly connected with guide plates 6, and the cross-section of the guide plate 6 is an arc shape. Since the external force is transmitted through the soil, when the soil moves with the external force, the guide plate 6 can guide the soil to the two ends of the buffer plate 7, thereby relieving the external force, reducing the phenomenon of external force acting on the enhanced double-wall corrugated pipe 1, and further enhancing the effect of the buffer component on external force processing.

[0042] In some specific embodiments, a locking groove 20 is opened on the outer wall of the sleeve 5, and the wire rope 14 is connected to the inner wall of the locking groove 20 by abutment. When the wire rope 14 is tied to the sleeve 5, the wire rope 14 and the inner wall of the locking groove 20 abut against each other. The abutment between the wire rope 14 and the inner wall of the locking groove 20 can provide a limiting effect for the wire rope 14, thereby avoiding the deviation of the wire rope 14 when it is tied to the sleeve 5, and ensuring that after the wire rope 14 is locked and fixed by the locking assembly, the wire rope 14 will not be unreliably fixed to the sleeve 5 due to deviation, thereby causing the sleeve 5 to loosen.

[0043] In some specific embodiments, the locking assembly includes: a nut 15, a locking head 16 and a mating head 19, the locking head 16 and the mating head 19 are respectively fixedly connected to the two ends of the wire rope 14, the locking head 16 and the mating head 19 are abutted, the inner wall of the nut 15 is threadedly connected to the locking head 16 and the mating head 19, and the bottom end of the nut 15 is abutted against the wire rope 14. When the wire rope 14 is fixed by the locking assembly, the locking head 16 and the mating head 19 are abutted together, and the worker threadably connects the nut 15 to the outer walls of the locking head 16 and the mating head 19. The nut 15 fixes the two by threaded connection with the locking head 16 and the mating head 19. At the same time, the nut 15 abuts against the wire rope 14 to ensure that there is no excess length after the wire rope 14 is fixed to the casing 5, thereby ensuring that the wire rope 14 is fully fixed to the casing 5.

[0044] In some specific embodiments, a plurality of limiting grooves 17 are provided at one end of the locking head 16 close to the mating head 19. The cross-section of the limiting groove 17 is triangular. The inner wall of the limiting groove 17 is abutted and connected with the limiting teeth 18. The limiting teeth 18 are fixedly connected to the side end of the mating head 19. When the locking head 16 and the mating head 19 are abutted, the limiting teeth 18 fixed to the mating head 19 are inserted into the limiting groove 17, and the inner wall of the limiting teeth 18 abuts against the limiting groove 17, thereby avoiding the vertical misalignment of the locking head 16 and the mating head 19. At the same time, the locking head 16 and the mating head 19 are positioned to avoid the misalignment of the nut 15 when installed on the locking head 16 and the mating head 19, thereby achieving the effect of facilitating the installation of the nut 15 on the locking head 16 and the mating head 19.

[0045] Several embodiments of the present invention are described in detail above, but the embodiments of the present invention are not limited thereto and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
