Description

Technical Field

[0001] The utility model relates to the technical field of dredging and filling foundations, in particular to a large-area dredging and filling foundation structure. Background Art

[0002] Dredged soil is the soil excavated during dredging projects. Dredging is used to deepen shallow sections of rivers or bays to improve navigation or flood discharge capacity. Blowing dredged soil from excavated channels or harbors into nearby low-lying areas for land reclamation is an economically feasible and primary method. Dredged soil has traditionally been disposed of by discarding or dumping it into waters near the project.

[0003] At present, in the field of construction engineering, especially in the foundation treatment of dredged soil areas, it has always been an urgent problem to be solved. The traditional treatment methods mainly include directly excavating and transporting the dredged soil and then backfilling with new soil, or dumping the dredged soil as waste at a designated location. These traditional practices not only consume a lot of manpower and material resources, but also due to the instability and looseness of the dredged soil itself, it is difficult to fundamentally improve the overall stability of the foundation by simply replacing the soil. Among them, the stability of the foundation is indirectly improved by adding foundation piles. Although it can alleviate the problems caused by dredged soil to a certain extent, it is not easy to install a connecting frame between the foundation piles. The use of bolts requires the use of tools, and the installation efficiency is low. Therefore, a large-scale dredged fill foundation structure is proposed to solve the above problems. Utility Model Content

[0011] By adopting this technical solution, the provided card slot can facilitate the entry of the card block, thereby fixing the position of the card block.

[0012] Furthermore, the cross-section of the connecting frame is an inverted V-shape, water guide grooves are provided at both left and right ends of the upper surface of the connecting frame, and hydrophobic sand and dredged soil are laid on the upper and lower sides of the connecting frame.

[0013] By adopting this technical solution, as water is gradually discharged through the water channels and drainage holes, the load-bearing capacity and stability of the entire structure will be significantly improved.

[0014] Furthermore, positioning grooves are provided on the top and bottom of the fixing plate on the side facing the connecting seat, and the size of the inner cavity of the positioning groove is adapted to the size of the positioning block.

[0016] Furthermore, a sealing ring is fixed on the outer surface of the top of the threaded block, and the outer diameter of the sealing ring is larger than the inner diameter of the threaded hole.

[0017] By adopting this technical solution, the installed sealing ring can prevent the entry of hydrophobic sand and dredged soil, ensuring the smooth completion of the installation process.

[0018] Furthermore, a triangular hole is provided on the upper surface of the block, and the size of the inner cavity of the triangular hole is adapted to the size of the triangular column.

[0019] Furthermore, a triangular groove is provided on the inner bottom wall of the connecting seat, and the size of the inner cavity of the triangular groove is adapted to the size of the triangular column.

By pushing the fixed plates 304 fixed on the left and right sides of the connecting frame 303 from one side of the connecting seat 302, and then making the card block 305 enter the inner cavity of the card slot, the positioning block 306 slides in the inner cavity of the positioning slot until the back of the card block 305 is in contact with the inner wall of the connecting seat 302.

[0032] When the bolt 308 is in the unlock position, the screw 307 is locked and the locking nut 308 is unlocked, so that the bolt 308 can be unlocked when the bolt 308 is unlocked.

[0033] In this embodiment, a card slot is provided on the opposite side of the two connecting seats 302, and the size of the inner cavity of the card slot is adapted to the size of the card block 305. The cross-sectional shape of the connecting frame 303 is an inverted V shape, and water guide grooves are provided on the left and right ends of the upper surface of the connecting frame 303. The upper and lower sides of the connecting frame 303 are paved with hydrophobic sand and dredged soil. As the water is gradually discharged through the water guide grooves and drainage holes, the load-bearing capacity and stability of the entire structure will also be significantly improved.

[0034] Among them, the top and bottom of the fixing plate 304 facing the connecting seat 302 are both provided with positioning grooves, the size of the inner cavity of the positioning groove is adapted to the size of the positioning block 306, and the provided positioning groove and positioning block 306 can limit the movement of the fixing plate 304.

[0036] It should be noted that the fixing tube 301 is made of high-strength aluminum alloy to ensure good welding performance. The diameter of the drainage hole is set to be within the range of 3-5 cm, and the size of the water guide groove is within the range of 5-8 cm.

[0037] As can be understood, the prefabricated small unit blocks combined with the connecting frame 303 to form a complete frame not only facilitates production and processing, but also facilitates rapid assembly by workers, greatly improving convenience. No tools are required for operation, and the size of the connecting frame 303 can be flexibly adjusted to meet the needs of different projects, increasing flexibility.

[0038] The working principle of the above embodiment is:

[0039] (1) First, assemble the various components on site according to the predetermined design drawings to ensure that each support column 2 can stand upright and form a reliable connection with the ground. Next, fix the connecting frame 303 in turn, and then start the concrete pouring process. At the same time, the corresponding dredged soil and hydrophobic sand and gravel layers must be laid synchronously. As the water is gradually discharged through the water channel and drainage holes, the load-bearing capacity and stability of the entire structure will be significantly improved.

[0040] (2) When fixing the connecting frame 303, the fixing plates 304 fixed on the left and right sides of the connecting frame 303 can be pushed in from one side of the connecting seat 302, and then the clamping block 305 can be made to enter the inner cavity of the clamping slot. At this time, the positioning block 306 slides in the inner cavity of the positioning slot until the back of the clamping block 305 is in contact with the inner wall of the connecting seat 302. Then the triangular column 309 is aligned with the threaded hole 310 and moved downward until the triangular column 309 completely enters the inner cavity of the threaded hole 310. Then the turntable 308 is rotated. The rotation of the turntable 308 drives the threaded block 307 to rotate, so that the threaded block 307 moves into the inner cavity of the threaded hole 310 until the upper surface of the threaded block 307 is on the same horizontal line as the upper surface of the connecting seat 302. The bottom of the triangular column 309 enters the inner cavity of the triangular slot to fix the connecting frame 303 to the connecting seat 302, and further fixes the connecting frame 303 between the two adjacent support columns 2.
