Technical Field

[0001] This utility model belongs to the field of building engineering technology, and in particular relates to a prefabricated landscape retaining wall. Background Technology

[0002] Traditional retaining wall construction methods, such as cast-in-place concrete, brick masonry, or rubble masonry, have the following drawbacks:

[0003] Material waste: It is difficult to accurately control the amount of materials used during on-site construction, which easily leads to waste; Long construction period: It requires layer-by-layer formwork, pouring, and curing, which is a complex process with a long cycle; Ecological damage: Construction dust, noise and wet operations pollute the environment, and the structure is not waterproof, which disrupts the ecological cycle.

[0004] While existing prefabricated retaining walls can partially solve the above problems, they still suffer from issues such as insufficient stability of prefabricated component connections, lack of greening functions, and poor construction flexibility. Utility Model Content

[0005] The purpose of this utility model is to provide a prefabricated landscape retaining wall that solves the problems of shortening the construction period, reducing material consumption, improving ecological benefits, and realizing greening and planting functions by using prefabricated components for factory production and rapid on-site assembly.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A prefabricated landscape retaining wall includes: a U-shaped base, a prefabricated retaining plate fixed in the groove of the U-shaped base, a dry-hanging structure fixed to the surface of the prefabricated retaining plate by expansion bolts, and a drainage structure set on the prefabricated retaining plate.

[0008] Furthermore, the prefabricated retaining plate has a convex cross-section, and the concave structure on both sides allows multiple prefabricated retaining plates to form a spliced ​​structure.

[0009] Furthermore, the U-shaped base is provided with mounting grooves for fixing multiple prefabricated retaining plates.

[0010] Furthermore, the drainage structure includes a green space drainage ditch located behind the precast retaining slab and a drainage hole located in front of the precast retaining slab, wherein the drainage ditch and the drainage hole are connected.

[0011] Furthermore, the precast retaining plate has dimensions of 300mm thick, 1400mm wide, and 1290mm high, with an indentation depth of 150mm, and adjacent precast retaining plates are overlapped and spliced ​​through an indentation structure.

[0012] Furthermore, fine aggregate concrete is used to fill the gap between the precast retaining plate and the U-shaped base.

[0013] Furthermore, the dry-hanging structure includes galvanized angle steel keel and stone hanging parts. Beneficial effects

[0014] The prefabricated landscape retaining wall provided by this utility model has the following advantages:

[0015] Highly efficient construction: Precast components are manufactured in factories, and on-site assembly requires no curing, shortening the construction period by more than 30%;

[0016] Material savings: Precision prefabrication reduces on-site processing waste, and the use of auxiliary materials such as formwork is reduced by 50%;

[0017] Ecological and environmental protection: Dry-hanging technology reduces dust and wet operation pollution, while drainage systems and green structures promote ecological cycles;

[0018] Landscape integration: Decorative surfaces can be made of rammed earth slabs, natural stone, etc., and combined with plant planting to enhance aesthetics. Attached Figure Description
