Description

Technical Field

[0001] The utility model relates to the technical field of retaining walls in geotechnical engineering, and more specifically to an anchor plate assembled fill retaining wall. Background Art

[0002] Fill retaining walls are very common construction structures in site leveling, so retaining wall engineering remains a very challenging, high-risk and difficult subject.

[0003] Commonly used retaining walls include gravity retaining wall, counterweight retaining wall, pile-sheet retaining wall, cantilever retaining wall, buttress retaining wall, anchor retaining wall, anchor plate retaining wall, etc. Gravity retaining wall and counterweight retaining wall mainly use the weight of the wall to balance the lateral pressure of the soil, so the amount of masonry work is large; pile-sheet retaining wall mainly relies on the passive earth pressure of the soil below the inflection point to balance the lateral pressure of the soil, so the pile length is longer, the pile quality control is stricter, and the project cost is higher; cantilever and buttress retaining walls rely on the weight of the soil to balance the lateral pressure of the soil, but the foundation burial depth is relatively deep in soft soil areas; anchor retaining walls are generally used in mountainous areas and are often less used in soft soil areas; anchor plate retaining walls are generally used in areas lacking stone materials, but are not suitable for landslide and collapse areas. Utility Model Content

[0004] In view of the defects and shortcomings of the prior art, the utility model provides an anchor plate assembled retaining wall. All components of the utility model can be prefabricated, which makes it low-cost and fast to construct. The retaining wall uses the tension provided by the steel strands to balance the soil pressure at the retaining wall, and the pressure on the foundation soil is smaller than that of the conventional retaining wall. Since the retaining wall is composed of retaining blocks, it has strong adaptability to deformation. The angle between the steel strands and the horizontal plane is between 10 and 25 degrees. Under the action of the vertical component force generated by the tension, the anchor plate will be further inserted into the original stratum, which is more beneficial to the safety and reliability of the structure.

[0005] The technical solutions adopted are as follows:

[0006] An anchor plate assembled fill retaining wall, comprising:

[0007] The wall is formed by stacking and splicing retaining blocks;

[0008] An umbrella-shaped anchor plate is anchored in the soil and includes a plurality of anchor claws extending in a straight line from the top;

[0009] One end of the steel strand is connected to the umbrella-shaped anchor plate, and the other end passes through the wall and is connected to the anchor.

[0010] Optionally, the umbrella-shaped anchor plate is a flat plate, comprising three anchor claws extending in a straight line from the top, wherein two anchor claws are symmetrically arranged on both sides of the middle anchor claw, and the angle between the two inclined anchor claws and the middle anchor claw is between 30° and 45°.

[0011] Optionally, ends of the plurality of flukes away from the top end are in the form of pointed tips.

[0012] Optionally, the tip of the umbrella-shaped anchor plate is tilted downward toward the wall, and the angle with the vertical direction is between 15° and 30°. With the same area of ​​the anchor plate, this structure is more conducive to generating a greater anchor tension.

[0013] Optionally, the end of the steel strand connected to the wall is lower than the end connected to the umbrella-shaped anchor plate, and the angle between the steel strand and the horizontal plane is between 10 and 25 degrees. This inclined setting allows the tension of the steel strand on the umbrella-shaped anchor plate to produce a vertical component force. Under the action of the vertical component force, the umbrella-shaped anchor plate will be firmly inserted into the original stratum.

[0014] Optionally, the wall is formed by stacking and splicing convex retaining blocks.

[0015] Optionally, L-shaped retaining blocks are provided at the lowest end and the topmost end of the wall, so that the lowest end and the topmost end of the wall are flat.

[0016] Optionally, a retaining wall cap stone is connected to the top of the wall, and a prefabricated cup foundation is connected to the lowest end of the wall.

[0017] Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects:

[0018] (1) Since the retaining wall of the utility model is composed of retaining blocks, it has strong adaptability to deformation.

[0019] (2) The retaining wall uses the tension provided by the steel strands to balance the soil pressure at the retaining wall, and the pressure on the foundation soil is smaller than that of conventional retaining walls.

[0031] The embodiments of the present invention will be described below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that the described embodiments may be modified in various ways or combinations thereof without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims. In addition, in this specification, the drawings are not drawn to scale and the same reference numerals represent the same parts.

[0032] The retaining wall of the present application mainly utilizes the tension provided by the steel strands to balance the soil pressure at the retaining wall, and the pressure on the foundation soil is smaller than that of the conventional retaining wall; secondly, because the retaining wall is composed of retaining blocks, it has strong adaptability to deformation; finally, the angle between the steel strands and the horizontal plane is between 10 and 25 degrees. Under the action of the vertical force generated by the tensile force component, the anchor plate will be further inserted into the original stratum, which is more beneficial to the safety and reliability of the structure.

[0033] The present embodiment provides an anchor plate assembled fill retaining wall, comprising an umbrella-shaped anchor plate 1, a steel strand 2, a retaining wall cap stone 3, a wall body 8, a prefabricated cup-shaped foundation 6, and an anchor 7. The first convex retaining block 4 and the second convex retaining block 5 are used to be spliced ​​into a vertical retaining wall, and the retaining wall is erected in the prefabricated cup-shaped foundation 6. The cap stone is arranged at the top of the retaining wall, forming a whole with the retaining wall to protect the lower wall body. The umbrella-shaped anchor plate 1 is anchored in the soil body, one end of the steel strand 2 is used to connect with the umbrella-shaped anchor plate 1, and the other end is used to connect with the retaining wall, so as to anchor the retaining wall in the prefabricated cup-shaped foundation 6.

[0034] The umbrella-shaped anchor plate 1 may be in the shape of a flat plate, and includes three anchor claws extending in a straight line from the top, wherein two anchor claws may be symmetrically arranged on both sides of the middle anchor claw. Specifically, it includes a middle anchor claw 11, and inclined anchor claws 12 on both sides of the middle anchor claw 11, and the two inclined anchor claws 12 extend obliquely from the top to a direction away from the middle anchor claw 11 at the same or different inclination angles. In addition, a connection hole 14 is also arranged at the top, and one end of the steel strand 2 may be connected to the umbrella-shaped anchor plate 1 through the connection hole 14.

[0035] In some embodiments, ends 13 of the intermediate anchor claw 11 and the inclined anchor claw 12 away from the top end are in the form of pointed tips, so as to facilitate the insertion of the ends into the soil.

[0036] In some embodiments, the angle between the two inclined flukes 12 and the middle fluke may be between 30° and 45°.

[0037] In addition, the present application does not exclude that the umbrella-shaped anchor plate 1 is three-dimensional, that is, multiple anchor claws can be extended from the top in a straight line into the space, and the specific form is not described in detail here. Alternatively, other forms of anchor plates, such as square anchor plates, can be used instead of umbrella-shaped anchor plates.

[0038] In some embodiments, a wall 8 can be formed by stacking and splicing a first convex retaining block 4 and a second convex retaining block 5, wherein the first convex retaining block 4 includes a first rectangular block 41 with a rectangular cross section and a second rectangular block 42 connected to the first rectangular block 41 and having a smaller cross section than the first rectangular block 41, so as to form an overall cross section in the shape of a convex letter. The second convex retaining block 5 has the same structure and size as the first convex retaining block 4. Among them, the first rectangular block 41 with a larger cross section of the first convex retaining block 4 is located in the direction close to the soil, and the second rectangular block 42 with a smaller cross section is located in the direction away from the soil, while the first rectangular block with a larger cross section of the second convex retaining block 5 is located in the direction away from the soil, and the first rectangular block with a smaller cross section is located in the direction close to the soil. The wall 8 is formed by alternately stacking the first convex retaining block 4 and the second convex retaining block 5. Of course, it should be noted that in order to make the wall 8 complete and stable, retaining blocks are also provided at the upper and lower ends of the wall 8 to make the bottom and top stable. For example, the lowest and top ends of the wall 8 are both provided with L-shaped retaining blocks 9, wherein the L-shaped retaining block 9 at the bottom end coincides with the structure of the first convex retaining block 4, so that the lowest end of the wall 8 is a plane. Similarly, the L-shaped retaining block 9 at the top end coincides with the structure of the first convex retaining block 4, so that the top end of the wall 8 is a plane.

[0039] by Figure 1For example, the bottom end is an L-shaped retaining block 9, and then upwards are the first convex retaining block 4 and the second convex retaining block 5 alternately stacked until the top end is formed by the L-shaped retaining block 9 to form a plane.

[0040] Of course, the above stacking of the first convex retaining block 4 and the second convex retaining block 5 into a retaining wall to form the wall body 8 is only exemplary, and concave retaining blocks can also be provided, and the retaining wall is formed by plugging and stacking the concave retaining blocks and the convex retaining blocks. Figure 3 It is a schematic diagram of retaining block masonry, and the steel strand passes through the wall 8 and is connected to the anchor 7.

[0041] The retaining wall can be calculated and analyzed according to the continuous beam to determine the size of the retaining block. The connection between the steel strand and the wall can be used as a fulcrum to calculate the size of the retaining block according to the continuous beam verification, and the size of the retaining block can be calculated according to the shear force between each retaining block. The specific calculation method will not be described in detail here.

[0042] The retaining blocks forming the wall can be reinforced concrete structures, and cement mortar is used to build prefabricated concrete blocks. The height of the retaining blocks can be 1.5 to 2.0 meters, and the width is generally 2.0 meters. At the same time, according to the requirements of conventional retaining walls, necessary drainage holes and backfilling treatment behind the wall need to be set. Similarly, the umbrella-shaped anchor plate 1 can also be a reinforced concrete structure, or a prefabricated structure can be used.

[0043] The wall 8 is arranged in the prefabricated cup-mouth foundation 6. The top of the prefabricated cup-mouth foundation 6 has a notch for receiving the wall 8. The size of the notch can be set larger than the cross-sectional size of the wall 8, so that the wall 8 can be easily stacked and installed therein. For example, the two sides of the notch can be opposite to each other and extend upward in a gradually away manner, so that the size of the upper part is looser than the size of the wall 8, while the size of the lower part is more in line with the size of the wall 8, so that the lower end of the wall 8 is easier to combine with the notch. The bottom end of the prefabricated cup-mouth foundation 6 extends to both sides to form a stable foundation. After the wall 8 is assembled in the prefabricated cup-mouth foundation 6, the wall 8 can be combined with the prefabricated cup-mouth foundation 6 as a whole by pouring concrete.

[0044] The umbrella-shaped anchor plate 1 is connected to the retaining block through the steel strand 2. One end of the steel strand 2 is connected to the connection hole 14 of the umbrella-shaped anchor plate 1, and the other end passes through the wall 8. For example, if the first convex retaining block 4 and the second convex retaining block 5 are spliced ​​into the wall 8, the second convex retaining block 5 can be passed through, and the passed end is connected to the anchor. The steel strand can be set with a certain prestressed tension to keep the wall in a vertical state.

[0045] In some embodiments, the tip of the umbrella-shaped anchor plate 1 faces downward. Specifically, the tip is inclined downward toward the wall 8, and the angle with the vertical is between 15° and 30°. Moreover, since the angle between each anchor claw is 30° to 45°, this structure is more conducive to generating a greater anchor tension under the same area of ​​the anchor plate.

[0046] In some embodiments, the end of the steel strand connected to the wall is lower than the end connected to the umbrella-shaped anchor plate, so that the angle between the steel strand and the horizontal plane is between 10 and 25 degrees. Such an inclined setting makes the tension of the steel strand on the umbrella-shaped anchor plate produce a vertical component force. Under the action of the vertical component force, the umbrella-shaped anchor plate will be firmly inserted into the original stratum.

[0047] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
