Description

Technical Field

[0001] This utility model relates to a retaining wall structure for a stockpile, which is suitable for arranging retaining walls at the end or middle of the exit of a large sand and gravel aggregate stockpile, especially for retaining walls with multiple exits, and belongs to the field of civil engineering construction technology. Background Technology

[0002] Sand and gravel aggregates are indispensable and irreplaceable basic materials for engineering construction. With the progress of infrastructure construction, the supply and use of sand and gravel aggregates are gradually moving towards intensive, large-scale, standardized, and efficient development. Stockyards, as the storage link in the supply and use of sand and gravel aggregates, play a vital regulatory role.

[0003] To increase the scale and mechanization of stockpiles and meet environmental protection requirements, enclosed stockpiles such as grid structures and air-supported membrane structures are often used, with multiple trenches at the bottom for centralized conveyor belt unloading. Large retaining wall structures are often installed to accommodate the varying heights of the conveyor belts and reduce land occupation. However, due to the large height of these retaining walls, the aggregate at these locations is in a critical stability state, resulting in significant active earth pressure. Furthermore, the design of these retaining wall structures is challenging due to limitations imposed by the foundation soil conditions. Traditional methods, such as buttress-type and counterweight-type retaining wall structures, especially for tall retaining walls, result in large size, high cost, and complex foundation treatment. Therefore, it is essential to find a suitable retaining wall structure that offers a short construction period and relatively low cost. Utility Model Content

[0004] This utility model aims to provide a retaining wall structure for stockyards, which can reduce active pressure and lower the bearing capacity of the foundation. It features simple structure, easy construction, and low cost.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A retaining wall structure for a stockpile includes multiple longitudinally extending trenches. Its structural features include a wall with a cavity between the trenches, and a cantilevered retaining wall and an inclined retaining wall extending laterally at the outlet end of the trench. The tunnel and the cavity-filled walls form an unloading platform; The cantilever retaining wall extends upward relative to the top of the embankment, and the inclined retaining wall extends downward relative to the bottom of the embankment.

[0006] Based on the embodiments of this utility model, further optimizations can be made to this utility model. The optimized technical solutions are as follows: In a preferred embodiment of this utility model, the earthen tunnel, the cavity wall, the cantilever retaining wall, and the inclined retaining wall are rigidly connected to form an integral structure.

[0007] To facilitate the rapid entry of aggregates into the cavity, in a preferred embodiment of this invention, the wall with the cavity has an opening for accommodating stockpile materials.

[0008] In a preferred embodiment of this utility model, the height of the cantilever retaining wall is no more than 4m.

[0009] In a preferred embodiment of this invention, the inclined retaining wall forms a slope on the side facing the material in the stockpile. This inclined design reduces active earth pressure.

[0010] In a preferred embodiment of this invention, the bottom of the inclined retaining wall has a protrusion extending towards the ground level of the discharge line. By providing the protrusion, the base pressure is further reduced.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model makes full use of the natural filling of aggregate in the cavity and the unloading of the cavity partition, which greatly reduces the huge active earth pressure brought about by the large-angle material stacking, forms the self-balance of aggregate in the cavity, and achieves local anti-sliding stability.

[0012] 2. This utility model utilizes the tunnel structure to solve the problem of retaining wall overturning as a whole.

[0013] 3. The cavity and earth pressure reduction of this utility model further reduce the foundation pressure and improve the overall structural safety. It has the advantages of low engineering cost, simple structure, strong targeting, clear stress, and safety and reliability.

[0014] 4. This utility model forms an unloading platform by setting up a wall with a cavity in the alleyway. The aggregate in the stockpile naturally fills the cavity, realizing the local self-balancing of the sand and gravel aggregate in the cavity, greatly releasing the active earth pressure of the stockpile on the structure, and improving the structural safety.

[0015] 5. This utility model improves the overturning moment of the structure and solves the problem of cavity overturning stability by connecting the floor to the wall as a whole.

[0016] 6. This utility model achieves a rigid connection between the ground tunnel, the cavity wall, and the bottom inclined retaining wall. In particular, the ground tunnel and the cavity wall have high rigidity, forming an integral unloading platform, which further releases the huge active earth pressure brought by the large-angle material stacking, reduces the foundation pressure, and further improves the structural stability.

[0019] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0020] This embodiment provides a retaining wall structure at the outlet of a sand and gravel aggregate stockpile site. By setting a cavity structure, the active earth pressure and vertical pressure are reduced, thereby reducing the base pressure, enhancing stability, and meeting the engineering safety requirements.

[0021] The retaining wall structure of this embodiment includes multiple longitudinally extending trenches 1 at the bottom of the storage yard, multiple longitudinally extending cavitary walls 2, transversely extending cantilever retaining walls 3 at the top of the trenches 1 and the cavitary walls 2, and transversely extending inclined retaining walls 4 at the bottom of the trenches 1 and the cavitary walls 2, as well as sand and gravel aggregate 5 disposed within the cavities and at the top of the retaining wall structure. The trenches 1, the cavitary walls 2, the cantilever retaining walls 3, and the inclined retaining walls 4 are rigidly connected to form an integral, shared load-bearing structure.

[0022] The tunnel 1 and the cavity wall 2 form an unloading platform; the cantilever retaining wall 3 extends upward relative to the top of the tunnel 1, and the inclined retaining wall 4 extends downward relative to the bottom of the tunnel 1. The inclined retaining wall 4 forms a slope facing the material in the storage yard. The bottom of the inclined retaining wall 4 has a protrusion extending towards the ground surface of the discharge line.

[0023] The cavity wall 2 has an opening to accommodate the stockpile materials. The height and width of the cavity wall 2 are sufficient to meet the requirements for the natural accumulation and stability of sand and gravel aggregates within the cavity, with a safety distance of not less than 0.5m in width. The earthen tunnel 1, the cavity wall 2, the cantilever retaining wall 3, and the sand and gravel aggregates 5 inside or on top of the cavity form a unified force, jointly bearing the active earth pressure exerted on the structure by the stockpile aggregates.

[0024] The specific construction steps for the retaining wall structure of the stockyard in this embodiment are as follows: Step 1: Excavate the site and pour the bottom inclined retaining wall 4.

[0025] Step 2: Simultaneously pour concrete for the ground tunnel 1 and the wall 2 with cavities.

[0026] Step 3: Pour the concrete for the ground tunnel 1 and the cantilevered retaining wall 3 at the top of the wall 2 with a cavity.

[0027] Step 4: Naturally fill the cavity with sand and gravel aggregate 5.
