Description

Technical Field

[0001] This invention relates to the field of retaining wall technology, and in particular to a retaining wall structure for civil engineering and its construction method. Background Technology

[0002] In civil engineering, retaining walls are core structures used to support slopes, prevent soil slippage and collapse, and protect surrounding buildings and roads. They are widely used in highways, railways, municipal engineering, water conservancy projects, and foundation pit support. With the rapid development of the civil engineering industry, higher requirements have been placed on the stability, drainage efficiency, ease of construction, and maintenance costs of retaining walls. Especially in complex conditions such as soft soil foundations, high embankment sections, and areas prone to heavy rainfall, the structural defects of traditional retaining walls have become increasingly prominent, and they can no longer meet the actual needs of engineering projects.

[0003] Currently, most retaining wall structures in existing technologies adopt integral casting or fixed connection methods. Their limiting and reinforcement structures are usually single-pole type, relying solely on the friction of the pole itself inserted into the soil to fix the base plate. Lacking secondary reinforcement mechanisms, in soft soil foundations, high embankments, or under heavy rainfall conditions, the limiting columns are prone to loosening and the base plate to slip, leading to overall instability of the retaining wall and seriously affecting project safety. Simultaneously, the drainage system of retaining walls often uses a single filter plate and drainage pipe structure. Over long-term use, the filter plates are easily clogged by silt, fine soil particles, plant roots, and other debris. Existing technologies often rely on manual disassembly and cleaning or periodic replacement of the filter plates, which is not only time-consuming and labor-intensive with high maintenance costs, but also requires suspending drainage during cleaning, easily causing water accumulation behind the wall and increased soil pressure, further exacerbating the risk of retaining wall instability. Therefore, this application proposes a retaining wall structure for civil engineering and its construction method. Summary of the Invention

[0004] The purpose of this invention is to address the problems in the prior art, such as insecure positioning, inconvenient dredging, difficult disassembly and assembly, and poor filtration effect, and to propose a retaining wall structure for civil engineering and its construction method.

[0005] The technical solution of the present invention: A retaining wall structure for civil engineering includes a base plate and a wall body. The wall body is detachably installed on the base plate. A connecting cavity is fixedly installed on one side of the wall body. Multiple through holes are opened on the surface of the connecting cavity. A material filling port is opened on the connecting cavity. The connecting cavity is filled with sand and gravel. A water conveying trough is fixedly installed on one side of the wall body. Multiple drainage pipes arranged at equal intervals are fixedly installed on the wall body. The two ends of the drainage pipes are located in the water conveying trough and the connecting cavity, respectively. A filter plate is fixedly installed in the drainage pipe. A limiting post is fixedly installed at the bottom of the base plate. The bottom of the limiting post is tapered. A limiting mechanism for reinforcing the base plate is provided on the limiting post. A dredging mechanism for unblocking the drainage pipes is provided in the water conveying trough.

[0006] Optionally, the limiting mechanism includes a threaded rod rotatably mounted on a limiting post, a connecting plate slidably mounted inside the limiting post, the connecting plate being threadedly connected to the threaded rod, guide plates hinged around the bottom of the connecting plate, a support plate fixedly mounted inside the limiting post, a plurality of equally spaced circumferentially arranged sliders slidably mounted on the support plate, the other end of the guide plate being hinged to the sliders, a limiting plate fixedly mounted on one end of the sliders, the limiting plate being tapered, and a plurality of equally spaced circumferentially arranged connecting holes being provided on the limiting post.

[0007] Optionally, the unblocking mechanism includes a reciprocating screw rotatably installed in a water delivery tank, a sliding plate slidably installed in the water delivery tank, the reciprocating screw threadedly connected to the sliding plate, a plurality of first guide blocks fixedly installed at one end of the sliding plate, the first guide blocks being slit-faced, a fixing block fixedly installed in the drain pipe, a spring fixedly installed on the fixing block, a stop block slidably installed in the drain pipe, one end of the spring being fixedly connected to the stop block, a second guide block fixedly installed at the top of the stop block, the second guide block being slit-faced, a unblocking plate fixedly installed at the bottom of the stop block, the unblocking plate being provided with a plurality of unblocking burrs, and a drain outlet opened at the bottom of the water delivery tank.

[0008] Optionally, a plurality of connecting columns are fixedly installed on one side of the wall, and bolts are rotatably installed on both sides of the bottom of the connecting columns. Threaded holes are provided on the base plate, and the bolts are threadedly connected to the threaded holes.

[0009] Optionally, the base plate has an insertion hole, and an insertion block is fixedly installed at the bottom of the connecting column, with the insertion block located inside the insertion hole.

[0010] Optionally, a turntable is rotatably mounted on the limiting post, and the turntable is fixedly connected to the threaded rod.

[0011] Optionally, a sliding groove is provided inside the limiting post, a limiting rod is fixedly installed on the connecting plate, the limiting rod is slidably connected to the sliding groove, and a fixing rod is fixedly installed at one end of the slider, the fixing rod being fixedly connected to the limiting plate.

[0012] Optionally, a motor is fixedly installed inside the water supply tank, and the output shaft of the motor is fixedly connected to a reciprocating lead screw.

[0013] Optionally, a connecting rod is fixedly installed at the bottom of the block, and one end of the connecting rod is fixedly connected to the unblocking plate.

[0014] Optionally, a method for constructing a retaining wall for civil engineering includes the following steps; Step 1: Lay out the layout according to the construction drawings, excavate the foundation pit for the retaining wall installation, and clean up the gravel and loose soil at the bottom of the foundation pit to ensure that the bottom of the foundation pit is flat and compacted. Step 2: Hoist the base plate into the foundation pit, so that the limiting post at the bottom of the base plate is vertically driven into the foundation pit soil; rotate the turntable to drive the threaded rod to rotate, drive the connecting plate to move down, and push the slider outward through the guide plate, so that the limiting plate extends out of the connecting hole and penetrates into the surrounding soil, thus completing the limiting reinforcement of the base plate. Step 3: Hoist the wall to the top of the base plate, align the insert at the bottom of the connecting column with the insertion hole and insert it into position, then turn the bolt to lock it with the threaded hole, thus realizing the detachable installation of the wall and the base plate. Step 4: Fill the connecting cavity with sand and gravel through the loading port and compact it. Backfill soil on one side of the connecting cavity of the retaining wall, compact it in layers, and the water and soil on the back side of the wall flow into the water conveyance channel through the drainage pipe and are finally discharged from the drainage outlet.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects: This invention involves inserting a limiting post on the base plate into the ground, and using a rotating turntable to drive a threaded rod to rotate. The threaded rod drives a connecting plate to move downwards, and the connecting plate presses against the guide plates around the bottom. In turn, the guide plates push the sliders away from each other, allowing the limiting plate to extend out of the connecting hole and insert into the soil. This achieves secondary reinforcement of the limiting post, increasing the overturning and sliding safety factor of the retaining wall by more than 40%, and making it suitable for complex working conditions such as soft soil foundations and high fills.

[0016] Furthermore, the reciprocating screw is driven by a motor to rotate, causing the slide plate to reciprocate. The tangential surfaces of the first and second guide blocks engage, squeezing the stop block and moving the unblocking plate. This process clears burrs and pores in the filter plate, and the reciprocating motion of the unblocking plate is achieved by spring reset. This process sequentially clears all drainage pipes, improving drainage efficiency, simplifying maintenance, and reducing the frequency and cost of manual maintenance. Compared to traditional manual cleaning, this method effectively avoids problems such as water accumulation behind the wall and increased soil pressure, further protecting the structural safety of the retaining wall.

[0017] Furthermore, by using the positioning and matching of the insert block and the insertion hole, the wall and the base plate can be quickly positioned. Then, by using the threaded connection of the bolt and the threaded hole, the wall can be locked and fixed. When disassembling, the wall can be hoisted simply by unscrewing the bolt. This ensures the stability of the connection between the wall and the base plate and also enables quick assembly and disassembly, solving the pain points of traditional retaining walls that are difficult to assemble and disassemble and cannot be reused.

[0018] This invention solves the problems of existing retaining walls, such as insecure positioning, inconvenient dredging, difficult disassembly and assembly, and poor filtration effect, and achieves improvements in the stability, drainage efficiency, and construction convenience of retaining walls, as well as reduction in maintenance costs.

The wall 2 is detachably installed on the base plate 1. A connecting cavity 6 is fixedly installed on one side of the wall 2. Multiple through holes are opened on the surface of the connecting cavity 6. A material inlet 7 is opened on the connecting cavity 6. The connecting cavity 6 is filled with sand and gravel to filter the soil and facilitate drainage. A water conveying trough 3 is fixedly installed on one side of the wall 2. Multiple drainage pipes 18 are fixedly installed on the wall 2 at equal intervals. The two ends of the drainage pipes 18 are located in the water conveying trough 3 and the connecting cavity 6, respectively. A filter plate 25 is fixedly installed in the drainage pipes 18. A limiting post 5 is fixedly installed at the bottom of the base plate 1. The bottom of the limiting post 5 is tapered. A limiting mechanism for reinforcing the base plate 1 is provided on the limiting post 5. A dredging mechanism for unblocking the drainage pipes 18 is provided in the water conveying trough 3.

[0029] Example 2

[0030] like Figure 6 , Figure 8 and Figure 9 As shown, the limiting mechanism includes a threaded rod 26 rotatably mounted on a limiting post 5. A connecting plate 29 is slidably mounted inside the limiting post 5 and is threadedly connected to the threaded rod 26. Guide plates 33 are hinged around the bottom of the connecting plate 29. A support plate 34 is fixedly mounted inside the limiting post 5. Multiple sliders 35 arranged circumferentially at equal intervals are slidably mounted on the support plate 34. The other end of the guide plate 33 is hinged to the sliders 35. A limiting plate 31 is fixedly mounted on one end of the sliders 35. The limiting plate 31 is tapered. Multiple connecting holes 28 arranged circumferentially at equal intervals are provided on the limiting post 5. When the limiting post... When inserted into the ground, the threaded rod 26 is rotated, which drives the connecting plate 29 to move downward. The connecting plate 29 presses against the guide plates 33 around the bottom. The guide plates 33 drive the sliders 35 to move away from each other. The sliders 35 drive the limiting plate 31 at one end to move. The limiting plate 31 moves out of the connecting hole 28 and is inserted into the soil to reinforce the limiting column 5, further improving the stability of the base plate 1 and effectively preventing the base plate 1 from slipping and the limiting column 5 from loosening. Compared with the traditional limiting structure, the overturning and sliding safety factor of the retaining wall is increased by more than 40%, which is suitable for complex working conditions such as soft soil foundation and high fill.

The first guide block 17 at one end of the slide plate 16 contacts and squeezes the second guide block 19. The second guide block 19 drives the unblocking plate 24 to move inward. The spring 21 is compressed and deformed. The unblocking burrs on the unblocking plate 24 unblock the pores of the filter plate 25 to avoid blockage and affect drainage. As the slide plate 16 drives the first guide block 17 to move continuously, the squeezing of the second guide block 19 is released. The spring 21 rebounds and drives the second guide block 19 to reset. The reciprocating motion of the slide plate 16 can unblock the filter plate 25 in the drainage pipe 18 in sequence, improve the drainage effect, reduce the frequency and cost of manual maintenance. Compared with traditional manual cleaning, the maintenance efficiency is increased by more than 80%, and the maintenance cost is reduced by more than 60%.
