Description

Technical Field

[0001] This application relates to the technical field of slope support, and particularly to a reinforced concrete composite retaining wall. Background Art

[0002] Retaining walls are commonly used forms of slope support in geotechnical engineering. Their main function is to resist the lateral pressure of the soil mass, prevent slope sliding, collapse or erosion, thereby ensuring the safety of the project and the stability of the surrounding environment. According to the structural form and force characteristics, retaining walls can be divided into various types such as gravity type, cantilever type, counterfort type, and anchor type, which are suitable for different geological conditions, load requirements, and construction scenarios. When designing, key factors such as earth pressure calculation, bearing capacity of the foundation, drainage measures, and material selection need to be comprehensively considered to ensure its long-term stability and durability. In the fields of roads, building foundations, water conservancy projects, and mine slopes, the application of retaining walls is of great significance for controlling soil deformation and optimizing land use.

[0003] The prior art mainly adopts the following three solutions: First, the gravity retaining wall, which resists the downward sliding force of the slope soil mass through the self-weight of the wall; second, the counterfort retaining wall, which improves the structural integrity and material utilization rate through the reinforced concrete structure and counterfort design; third, the cantilever retaining wall, which relies on the combined action of the self-weight of the wall body and the backfill soil to maintain stability and is supported by a single-sided wall design.

[0004] Regarding the above related technologies, the gravity retaining wall has problems such as difficult construction quality control, poor structural integrity, and limited applicable height; the counterfort retaining wall is prone to slope instability during construction due to its large foundation width; the cantilever retaining wall has a large bending moment on the wall body due to its cantilever force type and limited applicable height. Summary of the Invention

[0005] In order to facilitate construction and improve the stability of the retaining wall, this application provides a reinforced concrete composite retaining wall.

[0006] The reinforced concrete composite retaining wall provided by this application adopts the following technical solution: A reinforced concrete composite retaining wall includes a first base wall, a second base wall, a first installation component, a second installation component, and a connecting beam provided between the first installation component and the second installation component. The first base wall and the second base wall are symmetrically arranged. The first installation component is arranged on one side of the first base wall close to the second base wall, and the second installation component is arranged on one side of the second base wall close to the first base wall. There are multiple connecting beams. One end of the connecting beam is slidably connected to the first installation component, and the other end is slidably connected to the second installation component. The sliding direction of the connecting beam is horizontal sliding.

[0007] By adopting the above technical solution, the space between the first installation component and the second installation component is used to fill with waste soil. When filling with waste soil, slide multiple connecting beams to the same side, and then fill with waste soil. When the filled waste soil approaches the connecting beams, place the multiple connecting beams at intervals, and continue to fill with waste soil until the space between the first installation component and the second installation component is completely filled with waste soil, thereby forming a retaining wall to support the slope. The arrangement of the connecting beams facilitates construction. The waste soil fills the space between the first installation component and the second installation component, improving the stability of the retaining wall.

[0008] Optionally, installation beams are detachably connected to one end of the first installation component close to the connecting beam and one end of the second installation component close to the connecting beam. The connecting beam is located between the two installation beams, and both ends of the connecting beam are slidably connected to the installation beams.

[0009] By adopting the above technical solution, when installing the connecting beam, after installing the installation beam at an appropriate position between the first installation component and the second installation component, then slide the connecting beam onto the installation beam in sequence, which is convenient for installing the connecting beam to an appropriate height to support the second base wall.

[0010] Optionally, the first installation component includes a first installation plate and a first support member. The first installation plate is detachably connected to the first base wall. The installation beam close to the first installation plate is slidably connected to the end of the first installation plate away from the first base wall. The sliding direction of the installation beam is vertical sliding. The first support member is arranged below the installation beam close to the first installation plate, and the first support member is used to support the installation beam close to the first installation plate.

[0011] By adopting the above technical solution, the first installation plate facilitates the installation of the installation beam. On the one hand, the first support member is used to support the installation beam. On the other hand, the height of the first support member is the installation height of the installation beam, which can be flexibly adjusted. Setting the installation beam facilitates placing the connecting beam between the first installation component and the second installation component, and also facilitates changing the position of the connecting beam. When filling with waste soil, it is convenient to place the connecting beam on the same side of the installation beam, reducing the interference of the connecting beam on the waste soil, so as to facilitate filling with waste soil.

[0012] Optionally, the second installation component includes a second installation plate and a second support member. The second installation plate is detachably connected to the second base wall. The installation beam close to the second installation plate is slidably connected to the end of the second installation plate away from the second base wall. The sliding direction of the installation beam is vertical sliding. The second support member is arranged below the installation beam close to the second installation plate, and the second support member is used to support the installation beam close to the second installation plate.

[0013] By adopting the above technical solution, when installing the installation beam on the second installation plate, the installation beam is slidably connected to the second installation plate vertically downward. When placing the installation beam, the second support member is first placed at the bottom of the second installation plate. On the one hand, the second support member is used to support the installation beam. On the other hand, the height of the second support member is the installation height of the installation beam, which can be adjusted flexibly.

[0014] Optionally, the first support member has the same structure as the second support member. The first support member includes a plurality of support blocks and a plurality of heightening blocks. The plurality of support blocks are arranged at intervals, and there is a heightening gap between the plurality of support blocks. The heightening blocks are located in the heightening gap, and fixing pins are provided on the heightening blocks for fixing the heightening blocks on the first installation plate or the second installation plate.

[0015] By adopting the above technical solution, when adjusting the height of the first support member or the second support member, the height of the installation beam can be easily adjusted by increasing or decreasing the heightening blocks and the support blocks.

[0016] Optionally, a plurality of jacks are vertically spaced apart near the fixing pins on the first installation plate and the second installation.

[0017] By adopting the above technical solution, the plurality of jacks facilitate the fixing of the heightening blocks during installation.

[0018] Optionally, a plurality of support beams are also spaced apart on the top of the first installation plate, and both ends of the support beams are detachably connected to the first installation plate and the second installation plate respectively.

[0019] By adopting the above technical solution, after filling between the first installation plate and the second installation plate, the plurality of support beams are sequentially fixed on the top of the first installation plate, so that the plurality of support beams support the first installation plate and the second installation plate, improving the stability of slope protection.

[0020] Optionally, a bottom base layer is provided at the bottoms of the first base wall and the second base wall. One end of the bottom base layer close to the slope extends into the slope. The second base wall is arranged close to the slope, and the second base wall is higher than the first base wall.

[0021] By adopting the above technical solution, a bottom base layer is provided at the bottoms of the first base wall and the second base wall. At the same time, a part of the bottom base layer extends out into the slope. The soil above the bottom base layer provides counterweight, which can increase the anti-sliding force of the second base wall and also increase the anti-overturning performance of the second base wall.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: By setting a first installation component, a second installation component, and a connecting beam disposed between the first installation component and the second installation component, and the connecting beam can slide horizontally to the same side, and at the same time, by adjusting the height of the installation beam, the height of the connecting beam can also be adjusted accordingly, so that the heights of the second base wall, the second installation plate, and the connecting beam can be set according to slopes of different heights, with high adaptability, convenient construction, and improved stability of the retaining wall; The second base wall is higher than the first base wall, the connecting beam and the support beam between the first installation plate and the second installation plate, so that the retaining wall combines the advantages of a gravity retaining wall, a counterfort retaining wall, and a cantilever retaining wall, adapts to higher slope support, and can improve the stability of the supported slope.

Detailed Description of the Embodiments

[0026] The following will further describe the present application in detail Figure 1-6 with reference to the accompanying drawings.

[0027] An embodiment of the present application discloses a reinforced concrete composite retaining wall. Refer to Figure 1 , Figure 2 and Figure 3 . A reinforced concrete composite retaining wall includes a first base wall 1, a second base wall 2, a first installation component 3, a second installation component 4, and a connecting beam 5 disposed between the first installation component 3 and the second installation component 4. The first base wall 1 and the second base wall 2 are symmetrically arranged. The first base wall 1 and the second base wall 2 are cast-in-place concrete walls. The first installation component 3 is disposed on one side of the first base wall 1 close to the second base wall 2. The second installation component 4 is disposed on one side of the second base wall 2 close to the first base wall 1. There are four connecting beams 5. The connecting beam 5 is a steel beam. One end of the connecting beam 5 is slidably connected to the first installation component 3, and the other end is slidably connected to the second installation component 4. The sliding direction of the connecting beam 5 is horizontal sliding.

[0028] There is a gap between the first installation component 3 and the second installation component 4. The gap is filled with waste soil from the construction site, so that the interlayer between the first base wall 1 and the second base wall 2 is filled with waste soil. During filling, the multiple connecting beams 5 are slid to the same side. When the waste soil to be filled is about to approach the connecting beam 5, the connecting beams 5 are then placed in a spaced state, and then the waste soil is continuously filled, resisting the sliding of the slope soil. It has the characteristics of a gravity retaining wall, and at the same time can save materials. It not only has high material utilization rate and is convenient for construction, but also is easy to construct and improves the stability of the retaining wall.

[0029] Refer to Figure 1 , Figure 2 and Figure 3 . A bottom base layer 6 is provided at the bottoms of the first base wall 1 and the second base wall 2. One end of the bottom base layer 6 close to the slope extends into the slope. The second base wall 2 is disposed close to the slope. The second base wall 2 is higher than the first base wall 1.

[0030] Since the first base wall 1 and the second base wall 2 are connected by multiple connecting beams 5, the force distribution between the first base wall 1 and the second base wall 2 can be made more uniform and reasonable, having the characteristics of a counterfort retaining wall, and can be applied to slope support higher than that of a general gravity retaining wall. The first base wall 1 and the second base wall 2 confine the soil body and its gravity in the interlayer within the retaining wall structure, and can provide greater gravity with a narrower foundation, which is beneficial to reducing the foundation width.

[0031] Both the first base wall 1 and the second base wall 2 are perpendicular to the bottom base layer 6. At the same time, a part of the bottom base layer 6 extends out into the slope body, and the soil body above it provides a counterweight, which can increase the anti-sliding force of the second base wall 2 and also increase the anti-overturning performance of the second base wall 2. At the same time, the second base wall 2 is higher than the first base wall 1. A plurality of support beams 8 are provided at the tops of the second base wall 2 and the first base wall 1, so that the tops of the second base wall 2 and the first base wall 1 are in the form of a cantilever retaining wall, further improving the stability of the retaining wall.

[0032] Reference Figure 3 、 Figure 4 and Figure 5 ,One end of the first installation component 3 close to the connecting beam 5 and one end of the second installation component 4 close to the connecting beam 5 are both detachably connected with an installation beam 7. The installation beam 7 is a steel beam. In this application, the installation beam 7 is detachably connected to the first installation component 3 and the second installation component 4 by means of a slider-chute connection. The connecting beam 5 is located between the two installation beams 7, and both ends of the connecting beam 5 are slidably connected to the installation beam 7 through a slider-chute.

[0033] Further, referring to Figure 3 、 Figure 4 and Figure 5 ,The first installation component 3 includes a first installation plate 31 and a first support member 32. The first installation plate 31 is a steel plate, and the first installation plate 31 is detachably connected to the first base wall 1 by fixing screws or anchor bolts. In this application, it is fixing screws. The installation beam 7 close to the first installation plate 31 is slidably connected to one end of the first installation plate 31 away from the first base wall 1, and the sliding direction of the installation beam 7 is vertical sliding. The first support member 32 is arranged below the installation beam 7 close to the first installation plate 31, and the first support member 32 is used to support the installation beam 7 close to the first installation plate 31.

[0034] Specifically, referring to Figure 3 、 Figure 4 and Figure 5 ,The second installation component 4 includes a second installation plate 41 and a second support member 42. The second installation plate 41 is also a steel plate, and the second installation plate 41 is detachably connected to the second base wall 2 by fixing screws or anchor bolts. In this application, it is fixing screws. The installation beam 7 close to the second installation plate 41 is slidably connected to one end of the second installation plate 41 away from the second base wall 2, and the sliding direction of the installation beam 7 is vertical sliding. The second support member 42 is arranged below the installation beam 7 close to the second installation plate 41, and the second support member 42 is used to support the installation beam 7 close to the second installation plate 41.

[0035] In this application, the height of the first installation plate 31 is the same as the height of the first base wall 1, and the height of the second installation plate 41 is the same as the height of the second base wall 2.

[0036] Reference Figure 6, the first support member 32 and the second support member 42 have the same structure. The first support member 32 includes a plurality of support blocks 321 and a plurality of heightening blocks 322. The plurality of support blocks 321 are arranged at intervals, and there is a heightening gap between the plurality of support blocks 321. The heightening blocks 322 are located in the heightening gap. A fixing pin 33 is provided on the heightening blocks 322. The fixing pin 33 is used to fix the heightening blocks 322 on the first mounting plate 31 or the second mounting plate 41. In this application, both the support blocks 321 and the heightening blocks 322 are isosceles trapezoidal blocks. When the support blocks 321 are arranged, the short sides all face outward, so that there is a gap between every two adjacent support blocks 321, facilitating the insertion of the heightening blocks 322 into the gap between every two adjacent support blocks 321. Moreover, the support blocks 321 are slidably connected to the first mounting plate 31 and the second mounting plate 41 through waist-shaped grooves and waist-shaped blocks. A plurality of jacks 34 are vertically and equidistantly spaced apart near the fixing pin 33 on the first mounting plate 31 and the second mounting plate.

[0037] Refer to Figure 4 , three support beams 8 are also spaced apart on the top of the first mounting plate 31. The support beams 8 are also steel beams. The two ends of the support beams 8 are detachably connected to the first mounting plate 31 and the second mounting plate 41 through slider chutes. And after installing the support beams 8, fixing bolts are used to fix the support beams 8.

[0038] The implementation principle of a reinforced concrete composite retaining wall in an embodiment of this application is as follows: First, use anchor bolts or fixing screws, etc. to fix the first mounting plate 31 on the first foundation wall 1 and the second mounting plate 41 on the second foundation wall 2. Subsequently, place and install the first support member 32 and the second support member 42 respectively. Then fix the installation beam 7, and then sequentially install a plurality of connecting beams 5 on the installation beam 7. Fill the waste soil body between the first mounting plate 31 and the second mounting plate 41. After filling, the connecting beams 5 are arranged at intervals in the waste soil body. Place the support beam 8 on the top of the first mounting plate 31 and use fixing bolts to fix the support beam 8. Continue to fill the waste residue soil body until the waste soil body buries the support beam 8 to improve the stability of the retaining wall.
