Description

Technical Field

[0001] The utility model relates to a pressure-dispersed rib-plate suspended anchor retaining wall, belonging to the field of retaining engineering in the field of civil engineering. Background Art

[0002] The traditional L-shaped retaining wall, also known as the cantilever retaining wall or buttress retaining wall, is composed of a wall panel, a base plate, and buttresses, as shown in the attached figure of the specification. Figure 6 , which is a reinforced concrete structure; the stability of the retaining wall is guaranteed by the deadweight of the retaining wall and the weight of the backfill on the bottom plate. The retaining wall is generally cast in place as a whole, and there are many processes such as erecting formwork, tying steel bars, and pouring concrete, and the construction is extremely complicated; there are also prefabricated structures now, but they are basically divided into sections in the horizontal direction and prefabricated as a whole in the vertical direction. They have the disadvantages of large size, heavy weight, and are not conducive to transportation, which greatly limits their application, and the buttresses are vertical and cannot disperse the stress of the soil.

[0003] The traditional anchor plate retaining wall is composed of ribs, tie rods, anchor plates and panels, as shown in the attached figure of the specification. Figure 5 Its stability is ensured by tie rods and anchor plates. Although the structure is light, the system stability is poor, especially before filling, more temporary fixing measures must be adopted. During the filling process, there are also disadvantages of easy deformation and even instability. In addition, there is only one anchor plate at the same height of each rib column of the traditional anchor plate retaining wall. The soil in front of the anchor plate is subjected to greater force and is prone to plastic failure. Plastic failure refers to the deformation of a material under the action of external force exceeding its maximum elastic deformation. At this time, the material will not be able to return to its original state, but will retain a certain amount of deformation, making its working condition poor, and the parts will be completely destroyed over time.

[0004] To this end, the utility model provides a high-stability pressure-dispersed rib-plate suspended anchor retaining wall that does not require temporary support, can be prefabricated and is easy to transport. Utility Model Content

[0005] In view of this, the purpose of the present invention is to provide a high-stability pressure-distributed rib-anchored retaining wall that does not require temporary support, can be prefabricated and is easy to transport.

[0006] The utility model is achieved in this way:

[0007] A pressure-dispersed rib-plate suspended anchor retaining wall comprises a plurality of rib columns, wherein the rib columns are vertically arranged parallel to the soil slope to be supported;

[0009] A plurality of bottom plates for supporting the ribs, arranged between two adjacent ribs in the horizontal direction;

[0010] Several tie rods and anchor plates are arranged along the vertical direction of the soil and are located in the longitudinal direction of the rib column toward the inside of the soil. One end of the tie rod is connected to the rib column, and the other end is located inside the soil, and this end is provided with several anchor plates for sharing the soil stress.

[0011] As a further improvement, the cross-sectional shape of the panel and the bottom plate is a hollow polygon.

[0012] As a further improvement, the cross-sectional shape of the panel and the bottom plate is rectangular.

[0013] As a further improvement, the rib column is an L-shaped structure, the vertical portion of the rib column is in contact with the soil slope, and the end of the horizontal portion of the rib column is located in the soil.

[0014] As a further improvement, the cross-sectional shape of the rib column is I-shaped, T-shaped, box-shaped or rectangular.

[0015] As a further improvement, each rib column has at least two anchor plates at the same height.

[0016] As a further improvement, the pull rod is made of high-strength material.

[0017] As a further improvement, the pull rod is made of steel strands or steel bars.

[0018] As a further improvement, the anchor plate is a rectangular or circular structure made of reinforced concrete.

[0019] As a further improvement, the anchor plate is a rectangular or circular structure made of steel plate.

[0020] The beneficial effects of the utility model are:

[0021] ① The L-shaped rib columns of the utility model cooperate with the base plate to greatly increase the stability of the retaining wall system without the need for temporary support.

[0022] ② Compared with traditional anchor plate retaining walls, the utility model has more than one anchor plate at the same height of each rib column, forming a pressure-distributed structure, reducing the soil stress in front of a single anchor plate and reducing the possibility of damage to the soil in front of the plate.

[0023] ③ The rib columns, panels, tie rods and anchor plates of the utility model are all prefabricated components and can be made into I-shaped, cavity rectangular and other cross-sections, which greatly reduces the weight and facilitates production, transportation and assembly operations. The base plate can be prefabricated or cast in situ. Since it is cast on the ground, no spatial formwork is required, and casting in situ is more convenient, which enhances the tightness of the connection between the rib columns and the base plate.

[0035] A plurality of bottom plates 30 for supporting the rib columns 10 are arranged between two adjacent rib columns 10 in the horizontal direction, and the bottom plates are in contact with the bottom surface of the soil to be supported;

[0036] Several tie rods 40 and anchor plates 50 are arranged along the vertical direction of the soil and are located in the longitudinal direction of the rib column 10 toward the inside of the soil. One end of the tie rod 40 is connected to the rib column 10, and the other end is located inside the soil, and this end is provided with several anchor plates 50 for sharing the soil stress.

[0037] In one embodiment, the panel 20 and the rib column 10 are fixed by bolt connection.

[0038] As a possible specific implementation of the present invention, the cross-sectional shape of the panel 20 and the base plate 30 is a hollow polygon. After being prefabricated, the overall weight is reduced, which is convenient for transportation to the site, solving the problem that traditional L-shaped retaining walls and anchor plate retaining wall components are heavy and inconvenient to transport.

[0039] In one specific embodiment, the cross-section of the panel 20 and the bottom plate 30 is rectangular, which is convenient for field processing.

[0040] In one specific embodiment, the rib column 10 is an L-shaped structure, the vertical part of the rib column 10 is in contact with the soil slope, and the end of the horizontal part of the rib column 10 is located in the soil, which is used to share the soil stress and enhance the stability of the entire retaining wall. The bottom plate 30 is installed between the transition between the horizontal and vertical parts of the rib column 10 to support the rib column 10.

[0041] As a possible specific implementation of the present invention, the cross-sectional shape of the rib column 10 is I-shaped, T-shaped, box-shaped or rectangular.

[0042] As a possible specific implementation of the present invention, each rib column 10 has at least two anchor plates 50 at the same height.

[0043] As a possible specific implementation of the present invention, the pull rod 40 is made of high-strength material. High-strength material refers to a material with high strength, which is a material with greater strength, rigidity and durability than ordinary materials. It is usually made of high-purity metal, alloy, steel, ceramic, etc. These materials can maintain their shape and mechanical properties under large loads, and usually have corrosion resistance, wear resistance and other properties.

[0044] In one specific embodiment, the pull rod 40 is made of steel strands or steel bars, which have high hardness, good strength, rigidity and durability.

[0045] In one embodiment, the anchor plate is a rectangular or circular structure made of reinforced concrete, which is used to reinforce the foundation of the soil to enhance its stability and earthquake resistance.

[0046] In one specific embodiment, the anchor plate is a rectangular or circular structure made of steel plate.

[0047] Specific implementation steps and effects of this utility model:

[0048] S1, prefabricate the rib columns 10, the panels 20, the bottom plates 30, the tie rods 40 and the anchor plates 50 in a processing plant, and transport the processed components to the site for on-site assembly.

[0049] S2, leveling the foundation with plain concrete;

[0050] S3, installing the rib columns 10 according to the spacing, and simultaneously installing the base plate 30. The base plate 30 and the rib columns 10 may be in close contact, directly supporting the rib columns 10. The base plate 30 and the horizontal portion of the rib columns 10 may also be connected by bolts. Soil may be filled on the base plate 30 to form a fill layer to enhance the stability of the retaining wall.

[0051] S4, after installing one or two panels 20 between two adjacent ribs 10 along the soil slope, fill the space between the panels 20 and the soil slope and compact it according to the design requirements, with the panels 20 supporting the fill;

[0052] S5, repeating step S4 until the height of the anchor plate 50 is set, the tie rod 40 and a plurality of anchor plates 50 are installed, and the number of anchor plates 50 is greater than one, forming a pressure-distributed structure, reducing the soil stress in front of a single anchor plate, and reducing the possibility of damage to the soil in front of the plate;

[0053] S6, repeat steps S4 and S5 until the retaining wall reaches the designed height. No temporary support is required and the height of the retaining wall is not restricted.

[0054] S7, according to design requirements, tension the tie rods 40 at all levels and lock the tie rods 40 and anchor them on the airside of the rib column 10.

[0055] It should be noted that the bottom plate 30 does not need to be prefabricated, and can be directly cast with concrete on the leveled ground between two adjacent rib columns 10 without using spatial formwork, which is convenient and quick.

[0056] In summary, the rib columns 10, panels 20, tie rods 40 and anchor plates 50 of the present invention are all prefabricated components and can be made into I-shaped, hollow rectangular and other cross-sections, which greatly reduces the weight and facilitates production, transportation and assembly operations. The base plate 30 can be prefabricated or cast in situ. Since it is cast on the ground, no spatial formwork is required, and casting in situ is more convenient, which enhances the tightness of the connection between the rib columns 10 and the base plate 30. The spatial formwork mentioned here refers to the use of materials such as steel bars and wooden boards in construction to construct a template structure in the same shape as the building, so as to support and shape the concrete during pouring.

[0057] Secondly, compared with traditional anchor plate retaining walls, the utility model has more than one anchor plate at the same height of each rib column, forming a pressure-distributed structure, reducing the soil stress in front of a single anchor plate and reducing the possibility of damage to the soil in front of the plate.

[0058] Furthermore, the L-shaped rib column 10 of the present invention cooperates with the base plate 30 to greatly increase the stability of the retaining wall system without the need for temporary support. At the same time, the backfill on the base plate 30 can increase the overall stability of the retaining wall, and the rib column 10 is connected to the anchor plate 50 through the pull rod 40 to resist the soil pressure of the backfill on the retaining wall.

[0059] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
