Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a ribbed retaining wall structure with alternating large and small buttresses. Background Technology

[0002] Retaining walls are structural engineering facilities used to resist lateral earth pressure and prevent soil collapse or sliding. They are widely used in civil engineering, transportation, water conservancy, construction and other fields. Based on materials, structural forms, and uses, retaining walls can be divided into various types, such as gravity retaining walls, cantilever retaining walls, and buttress retaining walls. For example, the buttress retaining wall disclosed in Chinese utility model patent CN216379624U is a pile-supported buttress retaining wall, specifically including components such as a base plate, vertical arms, and ribs. The base plate and vertical arms serve as the main structure, while the ribs provide load-bearing capacity in the direction of soil retention. Simultaneously, the concrete structure fully covers the structure to ensure its integrity and sufficient structural strength. However, for retaining operations with less demanding stress conditions, reducing the number of ribs or adjusting the thickness of the vertical arms can optimize the workload. However, this optimization method easily leads to an overall decrease in load-bearing capacity. In construction environments with varying load-bearing requirements, localized lateral pressure can easily occur, and the optimized existing buttress retaining wall may not meet the needs. Utility Model Content

[0003] The purpose of this invention is to provide a ribbed retaining wall structure with alternating large and small buttresses. This invention can effectively optimize the engineering quantity while ensuring load-bearing reliability, and has excellent practicality.

[0004] The technical solution of this utility model is as follows: a rib-column retaining wall structure with alternating large and small arm arms, including a base plate, with perpendicular ribs at the inner end of the base plate, and multiple connecting beams between adjacent ribs; a retaining plate connected to the inner side of each rib is provided on the base plate; large and small arm arms are alternately provided on the base plate, and the large and small arm arms are connected to the corresponding ribs.

[0005] In the above-mentioned rib-column retaining wall structure with alternating large and small support arms, the top of the large support arm extends to the top of the rib column, and the outer end of the large support arm extends to the outer end of the base plate; the top of the small support arm extends to the middle of the rib column, and the outer end of the small support arm extends to the middle of the base plate.

[0006] In the aforementioned rib-column retaining wall structure with alternating large and small retaining arms, the arrangement range of the connecting beams corresponds to the middle and top of the inner side of the large retaining arm; the arrangement range of the hidden beams corresponds to the inner end, middle and outer end of the bottom of the large retaining arm.

[0007] In the aforementioned rib-column retaining wall structure with alternating large and small retaining arms, the arrangement range of the connecting beam corresponds to the top of the inner side of the small retaining arm; the arrangement range of the hidden beam corresponds to the inner end and middle of the bottom end of the small retaining arm.

[0008] In the aforementioned rib-column retaining wall structure with alternating large and small support arms, multiple main reinforcement bars are provided in both the rib columns and the base plate, and multiple stirrups are provided on the main reinforcement bars; multiple vertical distribution bars and horizontal distribution bars are provided in the large and small support arms, the vertical distribution bars are inserted into the base plate and anchored thereto, and the horizontal distribution bars are inserted into the rib columns and anchored thereto.

[0009] In the aforementioned rib-column retaining wall structure with alternating large and small buttresses, a hidden beam is provided in the base plate, and adjacent rib columns are connected and anchored through the connecting main bars in the connecting beam, and adjacent main bars in the base plate are connected and anchored through the hidden beam.

[0010] In the aforementioned rib-column retaining wall structure with alternating large and small retaining arms, the bottom of the retaining plate is connected to a hidden beam located at the inner end.

[0011] In the aforementioned rib-column retaining wall structure with alternating large and small buttresses, the outer ends of both the large and small buttresses are provided with multiple tensile main reinforcement bars that are anchored to the base plate and the rib columns.

[0012] In the aforementioned rib-column retaining wall structure with alternating large and small retaining arms, both the large and small retaining arms are right-angled triangles.

[0013] Compared with the prior art, this utility model adds ribs and connecting beams, which serve as the load-bearing structure of the retaining wall, thereby optimizing the thickness of the retaining wall while ensuring the integrity of the load-bearing surface. The equal-height arrangement of the buttresses is optimized into alternating large and small buttresses, and the amount of work for the small buttresses is optimized. The large and small buttresses are connected into a whole by horizontal connecting beams and a base plate, which work together with the ribs to transfer the load and achieve a balanced distribution of the load. This allows the buttresses to still support the lower part of the ribs where the load is concentrated, ensuring the reliability of the load-bearing capacity. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0017] Example: A ribbed retaining wall structure with alternating large and small buttresses, as shown in the attached figure. Figure 1 and attached Figure 2 As shown, the system includes a base plate 1, with perpendicular ribs 2 at the inner end of the base plate 1, and at least two connecting beams 4 arranged between adjacent ribs 2; retaining plates 12 connected to the inner sides of each rib 2 are cast together on the base plate 1; large support arms 5 and small support arms 6 are alternately cast on the base plate 1, connecting the corresponding ribs 2; the top of the large support arm 5 extends to the top of the rib 2, and the outer end of the large support arm 5 extends to the outer end of the base plate 1; the top of the small support arm 6 extends to the middle of the rib 2, and the outer end of the small support arm 6 extends to the middle of the base plate 1; the large support arms extend perpendicularly to the retaining plates. The system provides comprehensive coverage, with the small support arms covering the lower and middle sections of the retaining wall where stress is concentrated. The arrangement range of the connecting beam 4 corresponds to the middle and top of the inner side of the large support arm 5. The arrangement range of the hidden beam 3 corresponds to the inner, middle, and outer ends of the bottom of the large support arm 5, fully covering the distribution surface of the ribs while corresponding to the large support arm, facilitating force transmission. The arrangement range of the connecting beam 4 corresponds to the top of the inner side of the small support arm 6. The arrangement range of the hidden beam 3 corresponds to the inner and middle ends of the bottom of the small support arm 6, fully covering the distribution surface of the base plate while corresponding to the small support arm, facilitating force transmission. (See attached...) Figure 3 As shown, multiple vertically arranged main reinforcement bars 7 are arranged on the inner side of the rib column 2, and multiple horizontally arranged main reinforcement bars 7 are arranged in the bottom plate 1. Multiple stirrups 8 are tied or welded to the main reinforcement bars 7 to form a force transmission system. Multiple vertical distribution bars 9 and horizontal distribution bars 10 are arranged in the large arm 5 and small arm 6. The vertical distribution bars 9 are inserted into the bottom plate 1 and anchored thereto, and the horizontal distribution bars 10 are inserted into the rib column 2 and anchored thereto, forming a complete force transmission system to achieve reliable support. At least three connected hidden beams 3 are arranged between adjacent main reinforcement bars 7. Adjacent rib columns 2 are connected and anchored through the connecting main reinforcement bars in the connecting beam 4. Adjacent main reinforcement bars 7 in the bottom plate 1 are connected and anchored through the hidden beams 3 to improve the integrity and structural reliability of the bottom plate and rib columns. The bottom of the retaining plate 12 is connected to the hidden beam 3 located at the inner end. Multiple tensile main reinforcement bars 11 anchored to the bottom plate 1 are located inside the outer ends of the large arm 5 and small arm 6. Both the large arm 5 and small arm 6 are right-angled triangles.

[0018] Working principle: First, the retaining plate 12 directly bears the lateral earth pressure. The retaining plate 12 is tightly connected to the rib column 2, so the earth pressure can be transferred to the rib column 2. The connecting beam 4 between adjacent rib columns 2 plays a lateral stabilizing role, preventing the rib column 2 from tilting due to the force on a single column. The connecting beam 4 corresponding to the large arm 5 covers its inner middle and top, and the connecting beam 4 corresponding to the small arm 6 covers its inner middle, ensuring that the connecting beam 4 and the force-bearing area of ​​the arm are accurately matched, further improving the stress stability of the rib column 2.

[0019] The top of the large retaining arm 5 extends to the top of the rib column 2 and the outer end extends to the outer end of the base plate 1; the top of the small retaining arm 6 extends to the middle of the rib column 2 and the outer end extends to the middle of the base plate 1, focusing on supporting the lower part of the rib column 2, a region of concentrated stress. These two arms are arranged alternately and reliably connected by the concealed beam 3 and the connecting beam 4, forming a complete force transmission path. This effectively transfers the earth pressure borne by the retaining plate 12 and the rib column 2 to the base plate 1, while also providing lateral support for the rib column 2 and reducing the bending moment at the base of the rib column 2. Ultimately, this achieves coordinated stress distribution among the base plate 1, rib column 2, concealed beam 3, connecting beam 4, large and small retaining arms 5 and 6, and retaining plate 12, significantly optimizing the workload while ensuring load-bearing reliability.
