TECHNICAL FIELD
[0001] The present application relates to the field of building technology, in particular to a soil retaining device for building structure. BACKGROUND
[0002] In mountainous building design projects, the problem of height difference between various sites and buildings needs to be handled in the face of undulating terrain. In the traditional approach, when the indoor and outdoor height difference of the building is within 1 meter, the following methods are usually used: 1) thick masonry to resist the soil thrust, naturally forming a building foot; 2) cast-in-place concrete retaining wall; 3) setting a basement and using frame beams to reinforce the perimeter of the basement.
[0003] However, when the indoor and outdoor height difference of the building exceeds 1 meter, if the soil thrust is directly applied to the main structure of the building, it will pose a serious threat to the safety of the building, so a heavy retaining wall needs to be specially set up to offset the horizontal thrust of the soil, and the construction of the retaining wall needs to be kept a certain distance from the main building to avoid the collision between the retaining wall foundation and the building foundation, thereby ensuring the overall stability of the building.
[0004] However, the use of heavy retaining walls not only has high construction cost and long construction period, but also requires a certain retreat relationship with the main building, which limits the use of outdoor sites and has a certain impact on the design of the building facade. CONTENT OF THE INVENTION
[0005] To solve the problem of height difference between mountainous sites and buildings, the present application provides a soil retaining device for building structure.
[0006] The soil retaining device for building structure provided by the present application adopts the following technical solution:
[0007] A soil retaining device for building structure, characterized in that,
[0008] It comprises a soil layer, a concrete spray protection layer, a self-bearing masonry wall and a frame beam.
[0009] The concrete spray protection layer is arranged in close contact with the slope and is used to fix the soil layer.
[0010] The self-bearing masonry wall is arranged on the building foundation and is flush with the outer wall of the main building.
[0011] Or the self-bearing masonry wall slightly protrudes from the outer wall to naturally form a building foot.
[0012] The frame beam is vertically arranged between the top end of the concrete spray protection layer and the self-bearing masonry wall.
[0013] By adopting the technical scheme, when the mountain building operation is performed, the soil layer is treated to form an indoor area, an outdoor area and a slope, and a concrete spray protection layer is formed on the slope by using concrete spraying, so that the soil is fixed and the harm caused by sliding is avoided; the outer wall below the indoor elevation is formed by using a self-bearing masonry wall, which effectively resists the lateral pressure of the slope soil layer, plays a buffering and stabilizing role, and improves the safety of the device; the concrete spray protection layer and the self-bearing masonry wall are fixedly connected by using the frame beam, the device is reinforced, and the overall rigidity and stability of the soil retaining device are effectively improved; compared with the thick retaining wall, the soil retaining device solves the problem of height difference while greatly reducing the cost and maintenance difficulty of the building, and brings more possibilities and advantages to the design and construction of mountain buildings.
[0014] Preferably, the soil retaining device further comprises a cast-in-place bottom plate arranged at a part of the bottom layer of the building main body.
[0015] By adopting the technical scheme, the cast-in-place bottom plate is used in the partial area of the bottom layer of the building main body to ensure the close combination between the bottom plate and the building main body structure, avoid the security risks caused by insecure connection, and effectively block the direct influence of the soil body thrust on the building structure by separating the soil layer from the building main body structure, thereby reducing the risk of structural damage caused by soil body sliding or extrusion.
[0016] Preferably, the self-bearing masonry wall comprises a main wall for retaining soil and a surrounding wall arranged on the side of the wall away from the soil layer for surrounding the main wall.
[0017] By adopting the technical scheme, when the mountain building operation is performed, the main wall is used to directly bear the pressure of the soil body, effectively resisting the lateral pressure of the soil body; the surrounding wall is arranged on the side of the main wall away from the soil layer to avoid weathering and erosion of the traditional retaining wall exposed to the external environment, thereby prolonging the service life of the entire building; at the same time, the self-bearing masonry wall can also play a good buffering role when the slope collapses, the main wall can first bear the impact when the soil body accidentally collapses, and the impact force is dispersed to all parts of the wall, thereby reducing the damage to the building; when the main wall is damaged, the surrounding wall serves as a second line of defense to further reduce the loss caused by accidents.
[0018] Preferably, the concrete spray protection layer, the frame beam and the self-bearing masonry wall naturally form a cavity.
[0019] By adopting the technical scheme, the design of the cavity can further disperse and resist the lateral thrust of the soil body, enhance the soil retaining effect, effectively separate the soil body from the building main body structure, and avoid the direct action of the lateral thrust of the soil body on the building structure, thereby reducing the load of the building structure system and improving the overall stability of the building.
[0020] Preferably, a waterproof layer is arranged between the cast-in-place floor and the soil layer.
[0021] By adopting the above technical scheme, the penetration of underground water is effectively prevented, the safety hazards such as foundation settlement and structure cracking caused by water accumulation are avoided, and the stability and durability of the building structure are further enhanced. In the area with abundant rainfall or high underground water level, the setting of the waterproof layer can significantly reduce the erosion of underground water to the building structure, maintain the dry environment inside the building, effectively prevent the breeding of mold and wall dampness, reduce the maintenance and replacement cost caused by water erosion, and provide strong guarantee for long-term use of the building.
[0022] Preferably, the thickness of the concrete spray protection layer is 150-200 mm.
[0023] By adopting the above technical scheme, the 150-200 mm thick concrete spray protection layer provides strong adhesion and support, which can effectively fix the soil and prevent the soil layer from sliding or collapsing due to rain erosion, wind erosion and other natural factors. At the same time, the thickness of 150-200 mm avoids the concrete spray protection layer being too thick, thereby reducing the amount of material used and the construction difficulty, and further reducing the construction cost, improving the economy and practicality of the device.
[0024] Preferably, a support plate is arranged on the concrete spray protection layer, and an inclined plate is hinged to the support plate, and the end of the inclined plate is connected with the frame beam.
[0025] By adopting the above technical scheme, one end of the inclined plate is supported against the concrete spray protection layer through the support plate, and the other end of the inclined plate is closely connected with the frame beam, forming a stable triangular support structure, thereby enhancing the overall structural strength and effectively avoiding the collapse risk of the soil layer caused by external factors. By arranging the support plate, the stability of the inclined plate under stress is ensured, and at the same time, the impact of the concrete spray protection layer directly receiving the inclined plate is reduced, thereby improving the overall stability of the structure and prolonging the service life of the concrete spray protection layer.
[0026] Preferably, a plurality of drainage pipes communicating with the slope are arranged on the support plate, and a drainage groove is arranged on the soil layer at the bottom side of the slope.
[0027] By adopting the above technical scheme, the setting of the drainage pipes and the drainage groove cooperates with the waterproof layer arranged between the cast-in-place floor and the soil layer, effectively reducing the negative impact of underground water on the building structure, thereby ensuring the stability and durability of the building structure.
[0028] In summary, the present application has at least one of the following beneficial technical effects:
[0029] 1.The application fixes the soil effectively by setting a concrete spray protection layer on the slope of the soil layer; for the outer wall below the indoor elevation, a self-bearing masonry wall body design is adopted, which plays a good buffering and stabilizing role; by using the frame beam, the concrete spray protection layer and the self-bearing masonry wall are fixedly connected, further reinforcing the structure of the device; compared with the thick traditional retaining wall, the soil retaining device solves the problem of height difference while greatly reducing the construction cost and maintenance difficulty, bringing more innovative possibilities and significant advantages to the design and construction of mountainous buildings;
