Description

Technical Field

[0001] This application relates to the field of foundation technology, specifically a foundation structure. Background Technology

[0002] In construction engineering, foundation treatment in foundation pit engineering is divided into natural foundation and composite foundation. CFG pile composite foundation is widely used in building construction. However, in general industrial and civil buildings, the foundation pits, trenches, pipe trenches, and other shallow and weak foundations are extremely uneven. In addition, under the circumstances of tight construction schedules, high prices of construction materials, and upgraded dust control requirements, the choice of foundation treatment plays a crucial role in controlling the construction period, saving money, and ensuring the structural safety of the building.

[0003] A Chinese patent (publication number: CN207727601U) discloses a foundation structure in which multiple connecting rods are inserted into the soil of the foundation to enhance the connection strength between the foundation and the pile. However, since no connecting structure is provided when the pile is inserted into the foundation, it is inconvenient to limit the position of the pile located in the foundation, resulting in poor connection between the pile and the foundation, which affects the stability of the connection between the pile and the foundation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a foundation structure that has advantages such as easy positioning, thus solving the problem of inconvenient positioning.

[0005] To achieve the above objectives, this application provides the following technical solution: a foundation structure, including a foundation component, a base body movably connected inside the foundation component, a pile body movably connected inside the base body, and connection components for strengthening the stability of the pile body with the base body provided at both ends of the pile body.

[0006] The connecting assembly includes two connecting grooves, two connecting blocks, two sets of second semicircular blocks, a vertical block fixedly installed at the bottom of the inner cavity of the two connecting grooves, a first semicircular block fixedly installed on one side of the two vertical blocks, and an elastic structure fixedly installed on one side of the two sets of second semicircular blocks.

[0007] By adopting the above technical solution, the pile located in the base can be limited, thereby improving the connection strength between the pile and the base, and thus improving the connection strength between the pile and the foundation components, thereby improving the stability during the connection.

[0008] Furthermore, the two connecting grooves are respectively opened at the left and right ends of the top of the base, and the two connecting blocks are respectively fixed on the left and right sides of the pile body.

[0009] By adopting the above technical solution, the pile body and the foundation body can be snapped together and fixed together.

[0010] Furthermore, the lower end of the connecting block is provided with a through hole for the upright block and the first semicircular block to pass through its interior.

[0011] The above technical solution is adopted so that the first semicircular block can squeeze the second semicircular block.

[0012] Furthermore, the elastic structure includes two connecting plates, two sleeve rods, an anti-fall block fixedly installed on the top of the connecting plates, and a concave block fixedly installed on the opposite side of the two connecting plates, with a spring sleeved on the outer surface of the sleeve rods.

[0013] The above technical solution is adopted so that the two sets of second semicircular blocks on the left and right can move in opposite directions, so that the first semicircular block can be engaged between the two second semicircular blocks in the same set.

[0014] Furthermore, each of the concave blocks has a circular hole on one of its opposite sides for sliding on the outer surface of the sleeve rod.

[0015] The above technical solution facilitates the compression of the spring by the concave block.

[0016] Furthermore, the two sleeve rods are respectively fixed to opposite walls of the inner cavities of the two connecting blocks, and the sleeve rods are T-shaped.

[0017] The above technical solution is adopted to prevent the concave block from detaching from its outer surface when the spring pushes it to reset.

[0018] Furthermore, the top of the inner cavity of the connecting block is provided with a sliding groove for the top of the inner cavity to move to prevent the block from falling.

[0019] The above technical solution is adopted to ensure the stability of the two second semicircular blocks in the same group when they move within the cavity of the connecting block.

[0020] Furthermore, the top of the foundation component has a circular groove for the substrate to be located inside it, and the foundation component includes a soft soil layer and a cushion layer.

[0021] The above technical solution is adopted so that the substrate is located within the foundation component.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This foundation structure, by incorporating connecting components, can limit the position of piles located within the foundation, thereby enhancing the connection strength between the piles and the foundation. This allows the piles to be stably positioned within the foundation, increasing the spacing between the piles and the foundation components and improving stability during connection.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] Please see Figures 1 to 2 In this embodiment, a foundation structure includes a foundation component 1, a base 2 is movably connected inside the foundation component 1, a pile 3 is movably connected inside the base 2, and connection components for strengthening the stability of the pile 3 with the base 2 are provided at both ends of the pile 3.

[0030] In addition, a circular groove is provided at the top of the foundation component 1 for the base body 2 to be located inside it, so that the base body 2 can be located inside the foundation component 1.

[0031] It should be further explained that foundation component 1 includes a soft soil layer 11 and a cushion layer 12, which are combined to form the foundation component 1. The foundation component 1 is formed by excavating the soft soil layer within a certain range below the foundation bottom, and then backfilling and compacting a certain graded sand and gravel cushion layer material in layers according to certain requirements. This ensures that the bearing capacity of the backfilled sand and gravel meets the design requirements, while also accelerating the consolidation of the underlying soil layer and improving its bearing capacity. The thickness of the cushion layer is determined to be 0.57M to 2.09M, and its expression is σcz + σz ≤ ∱az, where ∱az is the design value of the foundation bearing capacity of the soft soil layer at the bottom of the cushion layer after depth correction; σcz is the standard value of the self-weight stress of the soil at the bottom of the cushion layer; and σz is the design value of the additional stress of the soil at the bottom of the cushion layer. This allows for the determination of the width of the cushion layer 12.

[0032] The bottom width of cushion layer 12 should meet the requirements for stress diffusion and preventing cushion layer 12 from being squeezed out to both sides. b′≥b+2ztanΘ Layered backfill material: The backfill material should preferably be laid at the same elevation on the foundation surface. If the depths are different, the foundation surface should be excavated into steps (step width not less than 500mm, step height the same as the thickness of each layer of backfill) or overlapped at a 1:1.5 slope. The overlap should be compacted. Construction should proceed in the order of deep to shallow. When segmented filling is necessary, the joints of each layer should be sloped (inclination greater than 1:1.5), with a 0.5~1.0m overlap of compaction tracks, and the staggered distance between upper and lower layers should not be less than 1m. Joints should not be located under the foundation, at wall corners, column piers, or other important locations.

[0033] To ensure uniformity and density of the replacement soil, it should be leveled and compacted with a bulldozer before being compacted by a heavy roller. When using a vibratory roller to compact crushed stone, fly ash, or slag-based soils, static compaction should be performed first, followed by vibratory compaction. When compacting replacement soil with rollers, the travel speed should be controlled, generally not exceeding: 2 km / h for flat rollers and vibratory rollers; and 3 km / h for sheep's foot rollers. When using a road roller for large-area replacement compaction, the compaction should proceed gradually from both sides towards the center, with each roller track overlapping by 15-20 cm to avoid missed areas. The wheel sinking should generally not exceed 10-20 mm. Areas that cannot be compacted by rollers should be tamped manually or with the assistance of small compaction equipment.

[0034] All unsuitable natural foundation soil layers at the bottom of the raft foundation are excavated and replaced with a 5:5 volume ratio of sand and gravel, with a compaction coefficient of not less than 0.97. The raft foundation composite foundation treatment no longer incorporates CFG piles. The foundation component 1 formed by the above method saves on investment, accelerates construction progress, and ensures the structural safety of the building.

[0035] Please see Figures 2 to 3 The connecting components in this embodiment include two connecting grooves 41, two connecting blocks 42, two sets of second semicircular blocks 45, a vertical block 43 fixedly installed at the bottom of the inner cavity of the two connecting grooves 41, a first semicircular block 44 fixedly installed on the opposite side of the two vertical blocks 43, and an elastic structure fixedly installed on the opposite side of the two sets of second semicircular blocks 45.

[0036] Secondly, two connecting grooves 41 are respectively opened at the left and right ends of the top of the base 2, and two connecting blocks 42 are respectively fixed on the left and right sides of the pile 3, so that when the pile 3 is moved into the base 2, the connecting blocks 42 can be moved into the connecting grooves 41.

[0037] In addition, the lower end of the connecting block 42 is provided with a through hole for the upright block 43 and the first semicircular block 44 to pass through it, so as to facilitate the connection between the first semicircular block 44 and the second semicircular block 45.

[0038] Please see Figure 3In this embodiment, the elastic structure includes two connecting plates 46, two sleeve rods 49, an anti-fall block 47 fixedly installed on the top of the connecting plate 46, and a concave block 48 fixedly installed on the opposite side of the two connecting plates 46, and a spring 410 sleeved on the outer surface of the sleeve rods 49.

[0039] Meanwhile, each of the concave blocks 48 has a circular hole on one side for sliding on the outer surface of the sleeve rod 49, so that it can compress the spring 410 sleeved on the outside of the sleeve rod 49.

[0040] Furthermore, the two sleeve rods 49 are respectively fixed to the opposite walls of the inner cavities of the two connecting blocks 42. The sleeve rods 49 are T-shaped to prevent the concave block 48 from falling off its outside when the spring 410 pushes the concave block 48 to move.

[0041] Furthermore, the top of the inner cavity of the connecting block 42 is provided with a sliding groove for the anti-drop block 47 to move through the top of its inner cavity, and the opposite sides of the two sets of second semicircular blocks 45 are respectively fixed to the opposite sides of the two connecting plates 46, which can ensure the stability of the connecting plates 46 moving within the connecting block 42, thereby enabling the two sets of second semicircular blocks 45 to move stably.

[0042] The working principle of the above embodiments is as follows:

[0043] In use, after the foundation component 1 is formed, the base body 2 is located in the circular groove of the foundation component 1. Multiple connecting rods are moved via a transmission mechanism to strengthen the connection between the base body 2 and the foundation component 1. The pile body 3 can then be inserted into the base body 2. As the two connecting blocks 42 gradually move into the two connecting grooves 41, the two upright blocks 43 and the two first semicircular blocks 44 can move into the interior of the connecting blocks 42, causing the two first semicircular blocks 44 to abut against the two lower second semicircular blocks 45. This allows the two first semicircular blocks 44 to push the two lower second semicircular blocks 45 to move relative to each other. The two lower second semicircular blocks 45 then drive the two connecting plates 46 to move relative to each other, causing the connecting plates 46 to push the concave block 48 onto the outer surface of the sleeve rod 49. The concave block 48 moves upward, allowing it to press against the spring 410 fitted outside it. As the connecting block 42 continues to move downward, the first semicircular block 44 moves to the top of the lower second semicircular block 45, thus preventing the first semicircular block 44 from pressing against the connecting plate 46 through the lower second semicircular block 45. This relieves the pressure on the spring 410, allowing the two connecting plates 46 to move in opposite directions via the two concave blocks 48. This causes the top of the first semicircular block 44 to abut against the bottom of the upper second semicircular block 45, thereby limiting the position of the pile 3 and strengthening the connection between it and the base 2, thus improving the stability of the connection between the pile 3 and the foundation component 1.
