Description

Technical Field

[0001] The utility model relates to the technical field of ground anti-settlement, in particular to a ground anti-settlement structure around a building. Background Art

[0002] Under the load of the building, the foundation soil is compressed and causes vertical deformation or sinking. Uniform settlement generally does little harm to the building, but when it is too large, it will also reduce the elevation of the building and affect its use; uneven settlement is more harmful to the building, causing additional stress in the building and causing cracks, or even partial component fractures, endangering the safety of the building. In order to ensure the stability of the building and its surroundings, a ground anti-settlement structure for the periphery of the building is provided.

[0003] The shallow strata of the land foundation of the sea reclamation project are silt sediment formed by filling and marine sedimentary silt clay, and the soil conditions are poor. Although the site has been treated with plastic drainage board vacuum preloading technology to improve its strength, its bearing capacity is still weak.

[0004] Under special geological conditions, the factory floor is directly made of concrete on the pond slag backfill layer. Although the pond slag has been compacted, the bearing capacity of the soil layer underneath is still weak, resulting in a large settlement of the concrete floor. However, since there are engineering piles underground at the foundation pedestal, and the foundation beam is connected to the pedestal, the settlement of the concrete floor at the pedestal and the beam is small, while the settlement in the middle is large. Especially for the ground in the factory that is open to traffic, the phenomenon of uneven settlement is more serious, with pit-shaped ground, and severe cracking of the concrete floor, which affects the appearance and use function of the building. Even if the ground is repaired twice, after a period of time, uneven settlement will still occur repeatedly, seriously affecting the normal production of the factory and causing economic losses. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an anti-settlement structure for the ground around a building, which solves the problem that even if the ground is repaired twice, uneven settlement will still occur repeatedly after a period of time, seriously affecting the normal production of the factory and causing economic losses.

[0006] To achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a ground anti-settlement structure around a building, including a pedestal beam system, a brick mold is arranged on the outer side of the pedestal beam system, a filling layer is arranged on the outer side of the brick mold, a closed layer is arranged on the front side of the brick mold, a steel bar layer is arranged above the closed layer, a gap is arranged between the brick mold and the pedestal beam system, and a cavity is arranged on the inner side of the brick mold.

[0007] Preferably, the sealing layer is a template or a prefabricated board.

[0008] Preferably, the inner side of the gap is filled with a plastic plate, and a protrusion is fixed to the front side of the plastic plate.

[0009] Preferably, a pond ballast layer is provided inside the landfill layer, and a crushed stone layer is provided below the pond ballast layer.

[0010] Preferably, a sandy soil layer is disposed above the pond ballast layer, and a breccia layer is disposed above the sandy soil layer.

[0011] Beneficial Effects

[0012] The utility model provides a ground subsidence prevention structure for the periphery of a building, which has the following beneficial effects: the ground subsidence prevention structure for the periphery of a building is achieved by the cooperation between the foundation and beam system, the brick formwork and the protrusions, so that the concrete floor is separated from the foundation and beam, and the concrete floor at that location is evenly subsided together with the concrete floor in the middle.

[0013] Through the coordination among the landfill layer, the brecciated layer and the sandy soil layer, good bearing capacity and stability are ensured by setting the brecciated layer. At the same time, the setting of the sandy soil layer is based on the high porosity and good water permeability of the sandy soil, which can avoid deformation and settlement caused by moisture of the foundation and improve the overall stability.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Under special geological conditions, the factory floor is directly made of concrete on the pond slag backfill layer. Although the pond slag has been compacted, the bearing capacity of the soil layer underneath is still weak, resulting in a large settlement of the concrete floor. However, since there are engineering piles underground at the foundation pedestal, and the foundation beam is connected to the pedestal, the settlement of the concrete floor at the pedestal and the beam is small, while the settlement in the middle is large. Especially for the ground in the factory that is open to traffic, the phenomenon of uneven settlement is more serious, with pit-shaped ground, and severe cracking of the concrete floor, which affects the appearance and use function of the building. Even if the ground is repaired twice, after a period of time, uneven settlement will still occur repeatedly, seriously affecting the normal production of the factory and causing economic losses.

[0021] In view of this, a structure for preventing the ground from settling outside a building is provided. Through the cooperation between the pedestal and ground beam system, the brick formwork and the protrusions, the structure separates the concrete floor from the pedestal and ground beam, allowing the concrete floor there to settle evenly together with the concrete floor in the middle.

[0022] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0023] Embodiment 1: Figure 1 and 3 It can be seen that a ground subsidence prevention structure for the periphery of a building comprises a foundation beam system 1, a brick formwork 2 is arranged on the outer side of the foundation beam system 1, a landfill layer 6 is arranged on the outer side of the brick formwork 2, a closed layer 4 is arranged on the front of the brick formwork 2, a steel bar layer 5 is arranged above the closed layer 4, a gap 13 is arranged between the brick formwork 2 and the foundation beam system 1, and a cavity 3 is arranged on the inner side of the brick formwork 2;

[0024] In the specific implementation process, it is worth pointing out that before laying the brick formwork 2, a cushion layer of sufficient strength must be poured at the laying position, the thickness should be greater than 100mm, and the width should exceed the brick formwork by 50mm on each side. The brick formwork on the inner side of the outer wall, considering the need to place the formwork or prefabricated panels, is built into a groove shape with a net width of 250mm, with a half-brick wall on the inner side and a 240mm wall on the outer retaining wall. A gap of 25mm to 50mm is left between the inner brick formwork and the ground beam. Through the cooperation between the pedestal and ground beam system 1, the brick formwork 2 and the gap 13, the structure allows the concrete floor to be separated from the pedestal and ground beam, allowing the concrete floor at this location to settle evenly with the concrete floor in the middle.

[0025] Further, the closed layer 4 is a template or a prefabricated board;

[0026] In the specific implementation process, it is worth pointing out that the gaps above the cap beam system 1 are not backfilled, and the upper part of the gaps is closed with wooden formwork or prefabricated panels as the supporting formwork for the concrete floor at that location;

[0027] Furthermore, the inner side of the gap 13 is filled with a plastic plate 12, and a protrusion 11 is fixed to the front side of the plastic plate 12, and the protrusion 11 is convenient for the user to grab the plastic plate 12;

[0028] In the specific implementation process, it is worth pointing out that the plastic plate 12 is used to fill the gap 13 between the foundation beam system 1 and the brick formwork 2 to prevent impurities from entering the gap 13 during the construction process;

[0029] Specifically, when the anti-settlement structure of the ground around the building is used, the gap above the pedestal beam system 1 is not backfilled, and the upper part of the gap is closed with a wooden formwork or a prefabricated plate as the supporting formwork of the concrete floor at that location. A steel skeleton is tied to the formwork, and the ground at the gap between the pedestal and the beam is made into a reinforced concrete cover plate. The cover plate is connected to the outer concrete floor as a whole, and the thickness and plate elevation are the same as the concrete floor. A 20mm thick foam plate is set at the intersection of the ground concrete and the middle structural column and the surrounding column walls. The foam board partition completely separates the ground concrete from the columns and walls. When the foundation settles, the brick formwork, concrete floor and cover floor settle evenly with the foundation, ensuring the flatness of the concrete floor and thus ensuring normal production in the factory. The process flow is briefly described as: backfilling and compacting the lower layer of earth → laying the brick formwork 2 → backfilling and compacting the soil outside the brick formwork 2 → laying the formwork or precast slab on the brick formwork 2 → tying the steel bars → fixing the isolation board → pouring concrete → mechanical calendering → ground maintenance → ground cutting.

[0030] Embodiment 2: By Figure 1 , 2 As shown in Figures 4 and 5, a pond ballast layer 9 is provided inside the landfill layer 6, and a crushed stone layer 10 is provided below the pond ballast layer 9;

[0031] In the specific implementation process, it is worth pointing out that the pond ballast layer 9 has excellent compression resistance, wear resistance, frost resistance, corrosion resistance, strong durability and is not easy to break, and the crushed stone layer 10 has the function of improving the bearing capacity;

[0032] Furthermore, a sand layer 8 is disposed above the pond ballast layer 9, and a breccia layer 7 is disposed above the sand layer 8;

[0033] In the specific implementation process, it is worth pointing out that the brecciated layer 7 ensures good bearing capacity and stability, and the sand layer 8, based on the high porosity and good water permeability of the sand, can avoid deformation and settlement caused by moisture on the foundation, thereby improving the overall stability;

[0034] Specifically, on the basis of the above-mentioned embodiment one, through the coordination between the landfill layer 6, the brecciated layer 7 and the sandy soil layer 8, the brecciated layer 7 is provided to ensure good bearing capacity and stability. At the same time, the sandy soil layer 8 is provided based on the high porosity and good water permeability of the sandy soil, which can avoid deformation and settlement caused by moisture of the foundation and improve the overall stability.

[0035] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions. The sentence "includes an element defined by ... does not exclude the existence of other identical elements in the process, method, article or device including the element".

[0036] In the present utility model, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the utility model according to the specific circumstances.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
