Description

Technical Field

[0001] The utility model relates to the technical field of gravity retaining walls, in particular to a gravity retaining wall structure. Background Technique

[0002] As a traditional retaining structure, the gravity retaining wall is widely used in the fields of landslides, slopes, and foundation pits. Its construction is convenient, the construction difficulty is small, the construction process is simple, and local materials can be used. The gravity retaining wall maintains the stability of the wall under the condition of lateral pressure with its own wall weight. It seems to be just a simple pouring work, but in water conservancy projects, there are relatively high requirements for aspects such as the embedding depth of embedded parts during the construction of the gravity retaining wall, the masonry and pouring materials of the retaining wall, the construction of the retaining wall structure, and the influence and precautions of different construction environments on the selection of the retaining wall construction method, stability, and safety. The common gravity retaining wall is generally set in a trapezoidal shape.

[0003] The existing patent (publication number: CN204982937U) discloses a multifunctional gravity retaining wall, which includes embedded parts, a wall body, and a drainage and water separation system; the wall body is composed of a wall panel, a cantilever structure, and a step; the cantilever structure is composed of a cantilever slab and a convex block arranged at the free end of the cantilever slab; the drainage and water separation system is composed of a cushion block, a filter layer behind the wall, a drain hole, and a drainage hole; the step is arranged at the lower part of the outer side of the wall panel, and the bottom of the step is connected to the top surface of the embedded part; the cushion block is arranged on the embedded part; the filter layer behind the wall is arranged on the cushion block; the drain hole is an outwardly inclined hole, and a row is arranged longitudinally at the lower part of the wall body. The water inlet of the drain hole behind the wall is connected to the filter layer behind the wall, and the bottom surface of the drain hole is connected to the top surface of the cushion block; the drainage hole is arranged under the convex block and arranged in a row longitudinally. The highest point of the bottom surface of the drainage hole is connected to the top surface of the aforementioned cantilever slab. The strength of the utility model is easy to adjust, the construction is convenient, and it can be popularized and used in projects such as urban roads, gardens, and urban water conservancy. The existing technology has the following problems: 1. After the existing gravity retaining wall is used for a long time, the stress anchor bolts inside it will age and need to be replaced to ensure the stability of the retaining wall. However, most of the existing gravity retaining wall anchor bolts do not have the function of replacement. Over time, the strength of the retaining wall will decrease; 2. The wall body of the existing gravity retaining wall is a vertical reinforced concrete wall, which causes a large moment arm when it is squeezed by the retained soil mass and is prone to collapse, and the structure still needs to be optimized.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the protection scope of the present utility model.

[0023] Please refer to Figures 1 to 7 , the present utility model provides a technical solution: a gravity retaining wall structure, including a wall body 1, the wall body 1 is fixedly connected to the top of the embedded part 2, two tenons 3 are fixedly connected to the bottom of the embedded part 2, a wall root 4 is arranged at the bottom rear side of the embedded part 2, a guardrail 5 is fixedly connected to the top of the wall body 1, a filter layer 6 is fixedly connected to the top of the wall root 4, a planting component 7 and a protective cover 8 are respectively arranged on the front side of the wall body 1, both the front and rear sides of the wall body 1 are inclined slopes, and the included angle between the slope on the rear side and the wall root 4 is 75°, and the included angle between the front slope of the wall body 1 and the wall root 4 is 55°; by designing the wall body 1 to be inclined backward as a whole, the bearing capacity of the wall body 1 is improved. At the same time, the embedded part 2 and the tenons 3 at the bottom of the wall body 1 can make the wall body 1 more firmly fixed in the soil. The included angles between the front and rear sides of the wall body 1 and the top surface of the embedded part 2 are acute angles. When the wall body 1 is subjected to the extrusion force from the rear hillside, the direction of the extrusion force can be changed, and the force direction is transmitted to the included angle direction between the wall body 1 and the embedded part 2. The wall body 1 under this structure has stronger bearing capacity, and the force received is dispersed to the bottom embedded part 2 and the tenons 3.

[0024] In this embodiment, as Figure 1 , Figure 2 , Figure 4 and Figure 5As shown in the figure, the planting component 7 includes a planting box 701 fixedly connected to the front side of the wall 1. A plurality of water outlet holes 702 are formed at the bottom of the front side of the planting box 701. The rear side of the planting box 701 is communicated with one end of a water seepage hole 703, and the other end of the water seepage hole 703 extends to the rear wall of the wall 1. The front side of the wall 1 is a stepped structure, and the space between each step is a slope design. A diversion plate 704 is fixedly connected to the top of the slope, and the top surface of the diversion plate 704 is a structure that is high in the middle and low on both sides; the planting component 7 provides a site for planting green ring plants, eliminating the need for later operations such as trenching and filling soil on the surface of the wall 1. Moreover, the rear side of the planting box 701 is communicated with the water seepage hole 703, enabling the moisture in the soil blocked by the rear side of the wall 1 to penetrate to the left side of the filter layer 6 and flow into the planting box 701 through the water seepage hole 703 to provide moisture for the greening plants. When rain comes, excessive rainwater on the mountain flows into the planting box 701 and flows out of the water outlet holes 702 on the front side of the planting box 701 to the top of the diversion plate 704, and then flows out to both sides through the top of the diversion plate 704, preventing the excess water from flowing into the next-level planting box 701 and causing the plants in the lower-layer planting box 701 to be soaked for a long time.

[0025] In this embodiment, as Figure 3 , Figure 6 and Figure 7 shown, a connecting shaft 801 penetrates through the bottom of one side of the protective cover 8, and the connecting shaft 801 is rotatably connected in a surface groove of the wall 1. An elastic pad 802 is fixedly connected to the bottom edge of the bottom surface of the protective cover 8, and the elastic pad 802 is clamped inside an installation groove 803. The installation groove 803 is opened on the front slope of the wall 1. A plug-in groove 804 is opened in the wall 1 directly below the protective cover 8. Two springs 805 are fixedly connected to the inner walls on both sides of the plug-in groove 804. One end of the two springs 805 close to the middle of the plug-in groove 804 is fixedly connected to a clamping block 806. The inner side of the clamping block 806 is in contact with the outer side of a stress anchor rod 807. The stress anchor rod 807 is inserted into the wall 1. The top end of the stress anchor rod 807 is fixedly connected to an installation plate 808. Two locking bolts 809 penetrate through both sides of the installation plate 808, and the bottom ends of the two locking bolts 809 are threadedly connected to internal threaded holes in the wall 1; the protective cover 8 can seal the plug-in groove 804, protecting the stress anchor rod 807 and the remaining fixing components inside, preventing the fixing components from being directly exposed outside and shortening the service life. When the stress anchor rod 807 ages and needs to be replaced, rotate the protective cover 8 around the connecting shaft 801 to open the protective cover 8. Then, unscrew the locking bolts 809, and then take out the stress anchor rod 807 from the wall 1 for replacement.

[0026] The usage method and advantages of the present utility model: When this gravity retaining wall structure is in use, the working process is as follows:

[0027] As Figure 1 , Figure 2 ,Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown in Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 , first, the protective cover 8 can seal the socket 804, protecting the stress anchor bolt 807 and the other fixing components inside, preventing the fixing components from being directly exposed outside, which may lead to a shortened service life. When the stress anchor bolt 807 ages and needs to be replaced, rotate the protective cover 8 around the connecting shaft 801 to open the protective cover 8. Then, unscrew the locking bolt 809, and then take out the stress anchor bolt 807 from the wall 1 for replacement. The planting component 7 provides a site for planting green-ring plants, eliminating the need for later operations such as digging trenches and filling soil on the surface of the wall 1. Moreover, the rear side of the planting box 701 communicates with the water seepage holes 703, enabling the water in the soil blocked by the rear side of the wall 1 to penetrate to the left side of the filter layer 6 and flow into the planting box 701 through the water seepage holes 703 to provide water for the greening plants. When rain comes, the rain on the mountain flows into the planting box 701 in excess and flows out from the water outlet holes 702 on the front side of the planting box 701 to the top of the diversion plate 704, and then flows out to both sides from the top of the diversion plate 704, preventing the excess water from flowing into the next-level planting box 701 and soaking the plants in the lower planting box 701 for a long time. The load-bearing capacity of the wall 1 is also enhanced. Specifically, by designing the whole wall 1 to be inclined backward, the bearing capacity of the wall 1 is improved. At the same time, the embedded parts 2 and tenons 3 at the bottom of the wall 1 can make the wall 1 more firmly fixed in the ground. The angles between the front and rear sides of the wall 1 and the top surface of the embedded part 2 are acute angles. When the wall 1 is subjected to the extrusion force from the rear hillside, the direction of the extrusion force can be changed, and the force direction is transmitted to the angle direction between the wall 1 and the embedded part 2. The wall 1 under this structure has a stronger bearing capacity, and the force received is dispersed to the bottom embedded part 2 and the tenon 3. The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only the preferred examples of the present invention and do not limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
