Description

Technical Field

[0001] The present invention belongs to the technical field of retaining walls, and in particular relates to an assembled ecological retaining wall and a construction method thereof. Background Art

[0002] When a highway is being built, some sections will pass through mountainous areas or steep slopes. Such terrain is prone to earth displacement, and gravel splashing onto the highway will cause danger to moving vehicles. For this reason, when building a highway, retaining walls are built on both sides of the highway to block the gravel and earth on both sides of the highway. When building a retaining wall, many factors need to be considered, such as the natural environment factors when the retaining wall is built. Because the retaining wall is generally made of concrete pouring, in the initial stage of concrete pouring, the lower the temperature, the longer the initial setting time and final setting time will be. In comparison, the extension of the final setting time is more obvious, which prolongs the pouring operation time. At the same time, low temperature conditions will reduce the hydration rate of concrete and affect the strength development of concrete. Therefore, the retaining wall after concrete pouring will have the problem of substandard strength. In addition, when operating in a low-temperature natural environment, some equipment cannot operate normally due to the low temperature when pouring retaining wall concrete. In addition, the operating efficiency and effect of the staff in a low-temperature environment are low, which seriously affects the completion time.

[0003] The invention with application number 2023100925374 discloses a prefabricated assembled retaining wall, including a prefabricated block and a mold for manufacturing the prefabricated block; the characteristics are: a convex portion is provided in the middle of the upper surface of the prefabricated block, a concave portion is provided in the middle position of the lower surface of the prefabricated block, two adjacent prefabricated blocks are stacked above and below, and the convex portion of the lower prefabricated block is embedded in the concave portion of the upper prefabricated block; the mold includes a bottom plate, a top plate, a length plate and a width plate; the bottom plate is raised in the middle position, and pads are fixedly connected to both sides of the bottom of the bottom plate. The pads are arranged along the width direction of the bottom plate, and threaded holes are provided at both ends of the pads. The top plate is above the bottom plate, and a rectangular opening extending upward is provided in the middle position of the upper surface of the top plate. A surrounding plate is provided on the edge of the top plate, and a through hole is provided on the surrounding plate. The surrounding plate is fixed to the upper edge of the length plate and the upper edge of the width plate by bolts and bolts. The disadvantages of the above retaining wall are: (1) the retaining wall has many parts. During installation, the prefabricated blocks need to be placed outside the steel cage first, and then the adjacent retaining walls need to be connected through connectors, which affects the construction efficiency of the retaining wall; (2) the retaining walls are connected by connectors, and the connection strength is poor, which affects the overall strength of the retaining wall.

DETAILED DESCRIPTION

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] An assembled ecological retaining wall, comprising a retaining wall unit 1, a rib column steel reinforcement cage 2, and a retaining wall base 3. A plurality of retaining wall units 1 are assembled to form a retaining wall wall structure. The retaining wall base 3 is used to provide a base foundation for the assembly of the retaining wall unit 1. The rib column steel reinforcement cage 2 is arranged at the splicing position of the retaining wall units 1, and a cast-in-place rib column 5 is formed by pouring through the rib column steel reinforcement cage 2. The splicing position of two adjacent retaining wall units 1 is fixed by a cast-in-place rib column 5. On the one hand, it can increase the assembly convenience of the retaining wall unit 1, and on the other hand, it can increase the connection strength between the cast-in-place rib column 5 and the retaining wall unit 1. A base steel reinforcement cage 3-4 is arranged in the retaining wall base 3, and the rib column steel reinforcement cage 2 is connected to the base steel reinforcement cage 3-4 to ensure good stability of the rib column steel reinforcement cage 2. And since both sides of the retaining wall unit 1 are respectively connected to the rib column steel reinforcement cage 2, by ensuring the strength of the rib column steel reinforcement cage 2, the overall strength of the assembled ecological retaining wall can be ensured after assembly.

[0026] The retaining wall unit 1 includes a retaining wall board 1-3 and support plates 1-4 arranged on both sides of the retaining wall board 1-3. An outer baffle 1-5 is connected to the outer edge of the support plate 1-4. The outer baffle 1-5, the support plate 1-4, and the retaining wall board 1-3 enclose a U-shaped retaining wall groove 1-1. After the retaining wall unit 1 is installed, at least part of the rib column steel reinforcement cage 2 extends into the retaining wall groove 1-1. After two adjacent retaining wall units 1 are assembled, the adjacent retaining wall grooves 1-1 are combined to form a rib column pouring cavity. The rib column steel reinforcement cage 2 is arranged in the rib column pouring cavity, and by pouring concrete into the rib column pouring cavity, a cast-in-place rib column 5 is formed in the rib column pouring cavity.

[0027] As an optional implementation manner, after two adjacent retaining wall units 1 are assembled, the rib column pouring cavity is in a completely closed state, so as to facilitate directly pouring a cast-in-place rib column 5 in the rib column pouring cavity.

[0028] The support plate 1-4 is inclined relative to the retaining wall board 1-3, so that the width of the retaining wall groove 1-1 decreases from the side close to the retaining wall board 1-3 to the side away from the retaining wall board 1-3, so that after the cast-in-place rib column 5 is poured, the width of the cast-in-place rib column 5 on the soil retaining side is larger, and the width of the cast-in-place rib column 5 on the vegetation planting side is smaller. That is, the cross section of the cast-in-place rib column 5 is in a conical or isosceles trapezoidal structure, ensuring better rigidity of the cast-in-place rib column 5.

[0029] A drainage window 1-6 is arranged on the retaining wall board 1-3, and the drainage window 1-6 is located above the vegetation planting board 1-2, so as to facilitate watering the vegetation on the vegetation planting board 1-2 through the drainage window 1-6.

[0030] The vegetation plate 1-2 is inclined relative to the bottom surface of the retaining wall unit 1, so that the vegetation plate 1-2, the retaining wall plate 1-3 and the support plate 1-4 together form a planting cavity, so as to facilitate the planting of vegetation on the vegetation plate 1-2. At the same time, through the setting of the vegetation plate 1-2, it is convenient to improve the strength of the retaining wall unit 1. Connecting ribs 1-7 are provided between the vegetation plate 1-2 and the retaining wall plate 1-3. On the one hand, the connection strength of the vegetation plate 1-2 is improved, and on the other hand, the overall strength of the retaining wall unit 1 can be further increased.

[0031] After the construction of the retaining wall is completed, the prefabricated ecological retaining wall is prone to cracking due to the retaining wall's own gravity and external forces. In order to reduce the cracking of the prefabricated ecological retaining wall, an expansion joint 5-1 is provided in the cast-in-place rib column 5. The expansion joint 5-1 is used to absorb the deformation of the prefabricated ecological retaining wall, thereby preventing the prefabricated ecological retaining wall from cracking.

[0032] The retaining wall base 3 includes a base plate 3-1, an assembly beam 3-2 connected to the base plate 3-1, and a base rib plate 3-3 connected to the base plate 3-1 and the assembly beam 3-2, a first steel cage 3-5 is provided in the base plate 3-1, a second steel cage 3-6 is provided in the assembly beam 3-2, the second steel cage 3-6 is fixedly connected to the first steel cage 3-5, and a third steel cage 3-7 is arranged obliquely between the second steel cage 3-6 and the first steel cage 3-5, thereby forming a base steel cage 3-4 to ensure the strength of the retaining wall base 3, and the base rib plate 3-3 is cast on the outside of the third steel cage 3-7. As a preferred embodiment, the bottom of the rib column steel cage 2 is fixedly connected to the first steel cage 3-5, and the two sides are fixedly connected to the second steel cage 3-6 to ensure the connection strength of the rib column steel cage 2. The retaining wall unit 1 is installed on the assembly beam 3-2, and the cast-in-place rib column 5 is cast on the assembly beam 3-2.

[0033] In order to further increase the strength of the assembled ecological retaining wall, a support rib 6 is connected between the cast-in-place rib column 5 and the retaining wall base 3. A rib plate steel cage 6-1 is arranged inside the support rib 6. One side of the rib plate steel cage 6-1 is fixedly connected to the rib column steel cage 2, and the other side is fixedly connected to the first steel cage 3-5. The overall strength of the assembled ecological retaining wall is further improved by the arrangement of the support rib 6. It should be noted that when forming the cast-in-place rib column 5 connected to the support rib 6, a gap should be left between adjacent retaining wall units 1. The gap size should be smaller than the width of the support rib 6 and larger than the width of the rib plate steel cage 6-1 to ensure the integrity of the support rib 6 and the cast-in-place rib column 5.

[0034] In order to further improve the integrity of the assembled ecological retaining wall, the assembled retaining wall also includes a buttress concrete layer 4, which is connected to the cast-in-place rib column 5 through the support rib 6. In some other embodiments, the buttress concrete layer 4 is connected to the cast-in-place rib column 5 by increasing the gap between the retaining wall units 1.

[0035] In some preferred embodiments, U-shaped connecting buckles 7 are connected between adjacent retaining wall units 1 , and the U-shaped connecting buckles 7 are arranged on one side of the buttress concrete layer 4 .

[0036] A top pressure beam 8 is provided on the top of the assembled ecological retaining wall, and the top pressure beam 8 is used to further increase the integrity of the assembled ecological retaining wall.
