Description

Technical Field

[0001] This utility model relates to the field of retaining wall technology, and in particular to a gravity retaining wall structure. Background Technology

[0002] Gravity retaining walls are retaining walls that rely on their own weight to resist lateral soil pressure. Gravity retaining walls can be constructed using masonry materials such as rubble, flagstone, or precast concrete blocks, or monolithically cast using flagstone concrete or regular concrete. Semi-gravity retaining walls can be constructed using concrete or lightly reinforced concrete. Gravity retaining walls can be built with stone or concrete and are generally made in a simple trapezoidal shape. Their advantages include the availability of locally sourced materials, ease of construction, and good economic efficiency. Therefore, gravity retaining walls are widely used in railway, highway, water conservancy, port, and mining projects in my country.

[0003] The existing retaining walls are all constructed by installing formwork on site and pouring concrete, which results in a long construction period and low overall construction efficiency. Utility Model Content

[0004] In order to solve the above-mentioned problems in the prior art, this utility model provides a gravity retaining wall structure that is modularly installed, convenient to construct, and highly efficient.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A gravity retaining wall structure includes several precast wall sections. The inner surface of each precast wall section is configured as an inner slope, and the outer surface of each precast wall section is configured as an outer slope. One end of each precast wall section has vertically distributed grooves, the upper end of which is connected to the top surface of the precast wall section. The lower end of the groove is provided with a connecting seat, and the connecting seat has vertically distributed connecting holes. The other end of each precast wall section has a protruding strip adapted to the groove, and the lower end of the protruding strip is provided with a connecting pipe that is inserted into the connecting holes.

[0007] By adopting the above technical solution, gravity retaining walls are directly assembled and connected using prefabricated wall components. Modular installation makes the overall construction convenient and efficient.

[0008] Preferably, the bottom surface of the precast wall is configured as a downward slope, with the outer end of the downward slope higher than the inner end. The downward slope forms an angle γ with the horizontal plane, the inner slope forms an angle β with the vertical plane, and the outer slope forms an angle α with the vertical plane, wherein 8°≤α≤12°, 15°≤β≤20°, and 5°≤γ≤8°. The inclined bottom surface of the precast wall better bears the horizontal component of the force, ensuring the stability of the retaining wall and preventing it from slipping horizontally. The inner and outer slopes further distribute the pressure in the horizontal and vertical directions, thereby improving the supporting strength.

[0009] Preferably, after the protruding strip is embedded in the groove, a gap is formed between the outer surface of the protruding strip and the groove, and the gap is filled with a wooden strip. The gap facilitates the smooth insertion of the protruding strip into the groove. After insertion, the gap is filled by tapping in the wooden strip. This not only prevents the effects of thermal expansion and contraction, but also provides a certain degree of buffering and shock absorption performance when the road surface inside the retaining wall is subjected to excessive loads, thus mitigating the local impact force on the precast wall.

[0010] Preferably, the precast wall has several drainage holes penetrating the inner and outer slopes, with the drainage holes distributed at an angle and the inner height of each drainage hole higher than its outer height. These drainage holes facilitate drainage and reduce water accumulation on the right side of the road.

[0011] Preferably, the inner slope of the retaining wall is provided with a sand and gravel filter layer, a lower clay water-blocking layer is provided between the bottom of the sand and gravel filter layer and the roadbed, an upper clay water-blocking layer is provided at the top of the sand and gravel filter layer, and the inner end of the drainage hole is located between the upper clay water-blocking layer and the lower clay water-blocking layer.

[0012] Preferably, the top surface of the precast wall has a row of mounting holes, in which columns are installed, and guardrails are fixed between the columns. The columns and guardrails serve a safety protection function.

[0013] Preferably, the outer slope is provided with several planting troughs for planting vegetation. The planting troughs are used to plant grass, ivy, Virginia creeper, and other vegetation. The vegetation can prevent direct exposure to sunlight and direct impact from rainwater, thus improving the stability of the outer slope. On the other hand, it can reduce the thermal stress of the precast wall and mitigate the impact of thermal expansion and contraction on the precast wall.

[0014] Therefore, this utility model has the advantages of modular installation, convenient and efficient construction, and good overall stability. Attached Figure Description
