Description

Technical Field

[0001] This utility model relates to the field of drainage hole technology in building construction, and specifically to a drainage hole filtration structure for retaining walls. Background Technology

[0002] As an important retaining structure in civil engineering, the effectiveness of the drainage system of a retaining wall directly affects the stability and service life of the structure. Drainage holes, as a key component of the retaining wall drainage system, play an important role in draining water accumulated behind the wall and reducing water pressure.

[0003] Traditional drainage hole filtration structures mostly use crushed stone reverse filter layers or single geotextile wrapping. Although they can achieve basic drainage functions, significant defects have gradually been exposed in actual engineering applications: First, geotextile is easily damaged by long-term water flow erosion and soil compression, leading to filter material loss, pore blockage, and a significant decrease in drainage efficiency over time; Second, standardized filtration structures are difficult to adapt to the diversity of drainage hole sizes in different projects, often requiring on-site customization, which not only increases construction costs but also affects project progress. Therefore, a device is needed to solve the above problems. Utility Model Content

Fixing mechanisms are provided on both sides of the bottom of the mounting frame to fix the geotextile. Through holes are provided in the middle of both the mounting frame and the replacement plate. The through holes are connected to drainage holes to drain accumulated water.

[0007] Optionally, the snap-fit ​​mechanism includes an L-shaped groove and a buckle. The L-shaped groove is formed on one side of the mounting bracket, and the buckle is fixedly connected to the back of the replacement plate. The buckle snaps into the L-shaped groove to fix the mounting bracket.

[0010] Optionally, there are multiple meshes, and each mesh is C-shaped, with a filling cavity formed between adjacent meshes for filling filter material.

[0011] Optionally, a positioning pin is fixedly connected to the bottom of the partition net, and a positioning hole is opened on the upper surface of the mounting bracket, with the positioning pin inserted into the inner wall of the positioning hole.

[0012] Optionally, a check buckle is fixedly connected to the inner wall of the positioning hole, and the check buckle engages with the outer surface of the positioning pin to fix the positioning pin.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a water filtration structure for a retaining wall drainage hole, including a baffle 1, a mounting frame 2 and a replacement plate 3. The baffle 1 is located on one side of the retaining wall, and a drainage hole 4 is provided in the middle of the baffle 1. The replacement plate 3 is detachably installed on one side of the drainage hole 4 and fits against the baffle 1.

[0023] The mounting frame 2 is detachably connected to the baffle 1 via a snap-fit ​​mechanism. A mesh 5 is detachably connected to the upper surface of the mounting frame 2 to filter soil. Fixing mechanisms are provided on both sides of the bottom of the mounting frame 2 to fix the geotextile. Through holes 6 are provided in the middle of both the mounting frame 2 and the replacement plate 3. The through holes 6 are connected to the drainage holes 4 to drain accumulated water.

[0024] The baffle 1 is set on one side of the retaining wall. After the replacement plate 3 is inserted into the drainage hole 4, the replacement plate 3 can be attached to the baffle 1. In the actual construction process, the replacement plate 3 of the corresponding size can be selected and installed on the baffle 1 according to the different sizes of the drainage hole 4. The mounting frame 2 is connected to the replacement plate 3 through the snap-fit ​​mechanism, thereby fixing the mounting frame 2 and the replacement plate 3 together. The mesh 5 is set on the mounting frame 2. When in use, the mesh 5 filters the water entering the drainage hole 4 and prevents the soil from flowing out of the drainage hole 4. The outside of the device is wrapped with geotextile to prevent the filter material inside the device from being lost.

[0025] In this embodiment, as a preferred solution, the snap-fit ​​mechanism includes an L-shaped groove 7 and a buckle 8. The L-shaped groove 7 is formed on one side of the mounting bracket 2, and the buckle 8 is fixedly connected to the back of the replacement plate 3. The buckle 8 snaps into the L-shaped groove 7 to fix the mounting bracket 2.

[0026] The mounting bracket 2 can be secured to the replacement plate 3 from top to bottom using the L-shaped groove 7 and the buckle 8, thereby fixing the mounting bracket 2 and the replacement plate 3 together.

[0027] In this embodiment, as a preferred option, a positioning block 9 is fixedly connected to the side of the replacement plate 3 near the baffle 1. The positioning block 9 is used to fix the relative position of the baffle 1 and the replacement plate 3.

[0028] There are two positioning blocks 9 on the replacement plate 3, which abut against the drain hole 4 from the top and bottom respectively, thereby fixing the relative position of the replacement plate 3 and the drain hole 4. The mounting bracket 2 is connected to the replacement plate 3 through the L-shaped groove 7 and the buckle 8, thereby fixing the relative position of the mounting bracket 2 and the replacement plate 3. With the help of the positioning blocks 9 set on the replacement plate 3, the positions of the three can be positioned to ensure that the through hole 6 and the drain hole 4 are aligned.

[0029] In this embodiment, as a preferred option, a clearance groove 10 is provided on one side of the mounting bracket 2, and a filter screen 11 is detachably connected to the inner wall of the clearance groove 10 to filter accumulated water.

[0030] The clearance groove 10 is recessed towards the mounting bracket 2, so that the filter screen 11 can be inserted into the clearance groove 10. When the filter screen 11 is installed on the mounting bracket 2, the filter screen 11 can close one side of the partition screen 5, so that multiple cavities are formed inside the partition screen 5, thereby adding water filter material inside the partition screen 5.

[0031] In this embodiment, as a preferred option, there are multiple meshes 5, and each mesh 5 is C-shaped, with a filling cavity formed between adjacent meshes 5 for filling filter material.

[0032] The multi-layered mesh 5 can be filled with a variety of different filter materials, such as sand, gravel, and pebbles, and can be selectively filled according to different terrain and geological conditions.

[0033] In this embodiment, as a preferred option, a positioning pin 12 is fixedly connected to the bottom of the partition 5, and a positioning hole 13 is opened on the upper surface of the mounting bracket 2. The positioning pin 12 is inserted into the inner wall of the positioning hole 13, and a backstop buckle 14 is fixedly connected to the inner wall of the positioning hole 13. The backstop buckle 14 is engaged with the outer surface of the positioning pin 12 to fix the positioning pin 12.

[0034] The outer circular surface of the positioning pin 12 is provided with an inwardly recessed ring. During the process of inserting the positioning pin 12 into the positioning hole 13, the positioning pin 12 will push the anti-reverse buckle 14 in the positioning hole 13 to move to both sides. After the positioning pin 12 is fully inserted, the anti-reverse buckle 14 will reset by its own elasticity, so that the anti-reverse buckle 14 and the outer circular surface of the positioning pin 12 are engaged together, thereby fixing the positioning pin 12 in the mounting bracket 2, and further fixing the partition net 5 on the mounting bracket 2.

[0035] In this embodiment, as a preferred solution, the fixing mechanism includes an installation groove 15 and a pressure strip 16. The installation groove 15 is opened on one side of the mounting frame 2, and the pressure strip 16 is detachably disposed on the inner wall of the installation groove 15 and is interference-fitted with the installation groove 15 to compress the geotextile.

[0036] When fixing the geotextile, the pressure strip 16 is pressed on one side of the geotextile and pushed into the installation groove 15, so that the pressure strip 16 can squeeze the geotextile, thereby fixing the position of the geotextile. The geotextile covers the top of the mesh 5 to prevent leakage of the internal filter material.

[0037] In this invention, the working steps of the device are as follows:

[0038] 1. When using, select the corresponding replacement plate 3 according to the size of the drain hole 4 on the baffle 1, fix the replacement plate 3 together with the mounting bracket 2, and install the filter screen 11 and the partition screen 5 on the upper surface of the mounting bracket 2.

[0039] 2. Depending on the current terrain and geology, select appropriate filter material to fill the cavity in the middle of the mesh 5. After filling, wrap the device with geotextile and fix the position of the geotextile with pressure strip 16.

[0040] 3. After fixing, insert the positioning block 9 on one side of the replacement plate 3 into the drainage hole 4. After installation, bury the device in the soil.
