Description

Technical Field

[0001] This application relates to the field of foundation reinforcement technology, and in particular to a soft soil foundation reinforcement structure. Background Technology

[0002] In building construction, soft soil foundations can easily lead to uneven settlement, tilting, and even structural damage, seriously affecting the safety and service life of the project. Existing fixed piles, when driven into soft soil, suffer from weak support due to their small transverse cross-sectional area and limited supporting area. This results in the surrounding soil being prone to settlement and deformation. Therefore, a soft soil foundation reinforcement structure is proposed. Utility Model Content

[0003] To address the problem that existing fixed piles have a small support area for soft soil, resulting in weak support force and easy settlement and deformation of the surrounding land, this application provides a soft soil foundation reinforcement structure.

[0004] The soft soil foundation reinforcement structure provided in this application adopts the following technical solution:

[0005] A soft soil foundation reinforcement structure includes a backfill pit and multiple sets of fixed piles. The fixed piles are arranged in four sets, with the lower part of the four sets of fixed piles inserted into the soft soil foundation located below the backfill pit. The upper part of each fixed pile is located inside the backfill pit. A support frame is provided between two adjacent sets of fixed piles. The support frame is connected to the middle of the fixed pile. Multiple sets of sleeve plates are fitted on the upper part of each fixed pile.

[0006] Preferably, each of the support frames includes a first connecting plate and a second connecting plate. One end of the first connecting plate and the second connecting plate are inserted into each other in the vertical direction and connected by a first bolt. Each of the fixed piles has a groove on its surface. The height of the groove is greater than the thickness of the first connecting plate and the second connecting plate. The other end of the first connecting plate and the second connecting plate is located inside the groove of the fixed pile on both sides.

[0007] Preferably, the support frame further includes multiple sets of reinforcing plates, which are perpendicular to each other, and the reinforcing plates are connected to the first connecting plate, the second connecting plate, and their overlapping parts by second bolts.

[0008] Preferably, each of the sleeve plates has a through groove adapted to the fixed pile at its center, and the sleeve plate can move up and down along the fixed pile. Each sleeve plate is connected to the fixed pile by a third bolt.

[0009] Preferably, the end of the first connecting plate away from the fixed pile has a slot, and the upper surface and one side of the outer surface of the slot are both set as open, and the end of the second connecting plate away from the fixed pile is adapted to the slot.

[0010] In summary, this application includes the following beneficial technical effects:

[0011] This invention, by setting up a support frame, can connect the fixed piles together, strengthening the connection between the fixed piles and improving their stability. The support frame also increases the support area, further enhancing stability. After backfilling the pit with soil, the sleeve plate increases the contact area between the fixed piles and the soil, enhancing the stability of the fixed piles. Attached Figure Description

[0017] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0018] This application discloses a soft soil foundation reinforcement structure, including a backfill pit 1 and multiple sets of fixed piles 2. There are four sets of fixed piles 2. The lower part of the four sets of fixed piles 2 is inserted into the soft soil foundation located below the backfill pit 1. The upper part of the fixed piles 2 is located inside the backfill pit 1. A support frame is provided between two adjacent sets of fixed piles 2. The support frame is connected to the middle of the fixed pile 2. Multiple sets of sleeve plates 3 are fitted on the upper part of each fixed pile 2.

[0019] In this embodiment, by setting up a support frame, the fixed piles 2 can be connected together, strengthening the connection between the fixed piles 2 and improving the stability of the fixed piles 2. The support frame can also increase the support area, further improving stability. After the backfill pit 1 is filled with soil, the sleeve plate 3 can increase the contact area between the fixed piles 2 and the soil, enhancing the stability of the fixed piles 2.

[0020] Furthermore, each support frame includes a first connecting plate 5 and a second connecting plate 9. One end of the first connecting plate 5 and the second connecting plate 9 are vertically inserted and connected by a first bolt 7. Each fixing pile 2 has a groove 4 on its surface, the height of which is greater than the thickness of the first connecting plate 5 and the second connecting plate 9. The other end of the first connecting plate 5 and the second connecting plate 9 is located inside the groove 4 of the fixing pile 2 on both sides. The end of the first connecting plate 5 away from the fixing pile 2 has a slot, with one side of the upper surface and the outer surface of the slot being open. The end of the second connecting plate 9 away from the fixing pile 2 is adapted to the slot.

[0021] Furthermore, the support frame also includes multiple sets of reinforcing plates 6, which are perpendicular to each other. The reinforcing plates 6 are connected to the first connecting plate 5, the second connecting plate 9, and their overlapping parts by second bolts 8.

[0022] In this embodiment, when connecting the fixing piles 2 using the first connecting plate 5 and the second connecting plate 9, firstly, the ends of the first connecting plate 5 and the second connecting plate 9 are placed inside the grooves 4 of the two sets of fixing piles 2, respectively. Then, the other end of the second connecting plate 9 is inserted into the slot, and the first connecting plate 5 and the second connecting plate 9 are connected using the first bolt 7. By setting the reinforcing plate 6, each set of the first connecting plate 5 and the second connecting plate 9 can be connected together. The first connecting plate 5, the second connecting plate 9, and the reinforcing plate 6 form a supporting grid, further improving stability.

[0023] Furthermore, each of the sleeve plates 3 has a through groove adapted to the fixed pile 2 at its center, allowing the sleeve plate 3 to move up and down along the fixed pile 2. Each sleeve plate 3 is connected to the fixed pile 2 by a third bolt 10.

[0024] In this embodiment, the third bolt 10 makes the sleeve plate 3 and the fixed pile 2 detachably connected. In actual application, the number of sleeve plates 3 and the distance between sleeve plates 3 can be set according to the geological conditions.
