Technical Field

[0001] This utility model relates to the field of drainage structures, and in particular to an integrally assembled blind drain. Background Technology

[0002] Blind drains refer to drainage and interception ditches set up in the roadbed or foundation, filled with coarse materials such as crushed stone and gravel, and covered with a filter layer or buried with permeable pipes, in order to lower the groundwater level in the subgrade area and prevent the subgrade from being soaked in water for a long time.

[0003] Chinese Patent Publication No. CN118581825A discloses a railway base drainage blind ditch component and its manufacturing and installation method. The railway base drainage blind ditch component includes an integral blind pipe and flexible connectors. Both ends of the integral blind pipe are provided with connecting flanges, and the integral blind pipe includes an integral pipe body.

[0004] However, the above technical solution has the following shortcomings: because the two ends of the flexible expansion joint are respectively fitted around the outer periphery of the two connectors, the inner circumferential channel of the integral blind pipe is smaller than the channel size of the flexible expansion joint. The two are misaligned, which affects the smoothness of drainage of the drainage blind ditch. Utility Model Content

Detailed Implementation

[0025] Example 1

[0026] like Figures 1-8 As shown, the integral assembled blind drain proposed in this embodiment includes a flange assembly, several sets of blind pipe assemblies, and several sets of flexible joints.

[0027] Several sets of blind pipe assemblies are aligned and connected. Each blind pipe assembly includes a pipe body 1, a permeable layer 4 disposed around the outer periphery of the pipe body 1, and a pressure strip 5 disposed around the outer periphery of the permeable layer 4 and connected to the pipe body 1. The pipe body 1 has permeable holes. The inner circumferential surface of the pipe body 1 is circular, and the outer circumferential surface is a composite surface with an upper semi-circular and a lower semi-rectangular portion. Specifically, the pipe body 1 includes an inner pipe section, an outer pipe section, and a reinforcing plate section. The inner pipe section is a circular pipe, and the outer pipe section has a composite structure of an upper semi-circular pipe and a lower semi-rectangular pipe, with the upper semi-circular pipe coaxially located outside the inner pipe section. Multiple reinforcing plates are arranged radially around the central axis of the inner pipe section and integrally connected between the inner and outer pipe sections. The pipe body 1, the pressure strip 5, and the permeable layer 4 are connected by screws.

[0028] like Figure 6 As shown, the flexible joint includes a flexible expansion sleeve 7, a reinforcing ring 71 embedded within the flexible expansion sleeve 7, and two mounting rings 8 respectively fitted at both ends of the flexible expansion sleeve 7. The mounting rings 8 enhance the compressive strength of the flexible joint. The flexible expansion sleeve 7 can be made of rubber material, with a zigzag undulating outer circumference, allowing for expansion, contraction, and angle adjustment, suitable for connecting two relatively inclined straight pipe sections. The mounting rings 8 are rigid structures, such as those made of hard plastic or stainless steel, and are coaxially installed at both ends of the flexible expansion sleeve 7, ensuring the structural regularity at both ends and thus ensuring that the flexible expansion sleeve 7 and the pipe body 1 can be aligned and connected.

[0029] The flange assembly includes a slide flange 2 connected to the left end of the blind pipe assembly or to the left end mounting ring 8 of the flexible joint via a connecting assembly, and a slotted flange 3 connected to the right end of the blind pipe assembly or to the right end mounting ring 8 of the flexible joint via a connecting assembly. The slide flange 2 and the slotted flange 3 can be installed on both the blind pipe assembly and the flexible joint via the connecting assembly, offering good versatility and eliminating the need to design flanges of different specifications for both blind pipe assemblies and flexible joints. The connecting assembly is detachably mounted on either the slide flange 2 or the slotted flange 3, and the slide flange 2 and the slotted flange 3 are detachably snap-fit ​​connected for easy assembly and disassembly. Both the slide flange 2 and the slotted flange 3 have through holes, which are connected by screws.

[0030] In this embodiment, the pipe body 1 is aligned and connected to each other, as well as to the flexible expansion sleeve 7, ensuring smooth drainage. When it is necessary to connect the pipe bodies 1, they can be connected into a straight pipe structure using the insert flange 2 and the groove flange 3. The number of connections depends on the required construction length. The ends of the pipe bodies 1 are aligned. When it is necessary to connect two straight pipes that are inclined to each other through a flexible joint, the insert flange 2 and the groove flange 3 with built-in connecting components are directly installed on the flexible joint, and then connected to the groove flange 3 and the insert flange 2 of the two adjacent straight pipes respectively, ensuring that the pipe body 1 and the flexible expansion sleeve 7 are aligned and connected.

[0031] Example 2

[0032] like Figures 1-8 As shown, in this embodiment, compared to Embodiment 1, the integral assembly blind drain proposed in this embodiment has an additional feature: the end face of the insert flange 2 has a first groove 201, and the end face of the slot flange 3 has a second groove 301 corresponding to the first groove 201. When the second groove 301 and the first groove 201 are aligned, a complete sealed installation space can be formed inside. A sealing ring 6 is embedded in the first groove 201 and the second groove 301. The upper part of the sealing ring 6 is semi-circular, and the lower part is semi-rectangular. It can play a sealing role in the sealed installation space, ensuring the sealing performance of the connection between pipe bodies 1 and the connection between pipe body 1 and flexible expansion sleeve 7.

[0033] Example 3

[0034] like Figures 1-8 As shown, the integral assembly blind drain proposed in this embodiment, compared with Embodiment 1, has a snap-fit ​​part 21 at the bottom of the insert flange 2 and a slot flange 3 at the bottom for the snap-fit ​​part 21 to engage with. The snap-fit ​​part 21 can engage inside the slot flange 31, thereby realizing the snap-fit ​​connection between the insert flange 2 and the slot flange 3. The snap-fit ​​connection can also position the connection process of the two flanges, ensuring that the two inner pipes 1 can be aligned and connected.

[0035] like Figure 2 and Figure 3As shown, the two ends of the slot portion 31 are sealed along its length (i.e., in the direction parallel to the radial direction of the inner tube portion of the tube body 1) to prevent the latching portion 21 from falling off along its length after being latched onto the slot portion 31. The side of the slot portion 31 has multiple retaining portions 311 that are latched to the latching portion 21. Specifically, the slot portion 31 uses the retaining portions 311 to achieve the latching connection with the latching portion 21. The bottom end of the latching portion 21 has a first inclined surface, and the top surface of the retaining portion 311 has a second inclined surface, which guides the latching process. Multiple notches 312 are formed between the multiple retaining portions 311 to reduce material consumption. The multiple spaced retaining portions 311 can be pushed open more smoothly by the latching portion 21, and rebound after the latching portion 21 is latched into place to limit the latching portion 21.

[0036] This embodiment improves the convenience of snap-fit ​​operation and ensures a regular and aligned snap-fit ​​connection by refining the snap-fit ​​connection structure of the insert flange 2 and the slot flange 3, thereby ensuring that the two pipe bodies 1 or the pipe body 1 and the flexible expansion sleeve 7 are aligned and connected.

[0037] Example 4

[0038] like Figures 1-8 As shown, the integral assembly blind drain proposed in this embodiment, compared with Embodiment 1, has the following differences: the connecting component in this embodiment includes an adapter cylinder 9 and a rubber ring 10. The adapter cylinder 9 is interference-fitted onto the inner circumferential surface of the insert flange 2 or the slot flange 3, and can be pushed off radially during disassembly. The rubber ring 10 is disposed on the inner circumferential surface of the adapter cylinder 9 and is sealed to the mounting ring 8, thus ensuring the sealing between the connecting component and the flexible joint.

[0039] Furthermore, such as Figure 7 and Figure 8 As shown, the inner circumferential surface of the adapter tube 9 is a circular surface and has an annular mounting groove. The rubber ring 10 is set in the mounting groove, and the rubber ring 10 can be installed securely. When it is fitted onto the flexible connector, the rubber ring 10 is not easy to shift or misalign.

[0040] In addition, connection holes can be provided on the outer periphery of the slide flange 2 and the slot flange 3. Screws are screwed into the connection holes, and the screws pass through the adapter sleeve 9 and the rubber ring 10 and are connected to the mounting ring 8, thereby improving the connection reliability of the flexible joint and the flange assembly.

[0041] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
