Description

Technical Field

[0001] This utility model relates to the field of foundation reinforcement structure technology, specifically to a foundation reinforcement structure for a port bulk cargo storage site. Background Technology

[0002] During the construction of a port bulk cargo yard, it is necessary to reinforce the ground strength of the yard through foundation reinforcement structures to prevent heavy cargo and construction machinery from damaging the ground.

[0003] In the prior art, application number 202223306786.9 discloses a foundation reinforcement structure for a port bulk cargo storage area, including a frame, reinforcement columns, port ground, steel reinforcement frame, transverse threaded bars, a mesh layer, a crushed stone filling layer, and an asphalt filling layer. The reinforcement columns are fixedly connected to the frame, and the port ground is fixedly connected to the outside of the frame. The steel reinforcement frame is fixedly connected to the inside of the reinforcement columns, and transverse threaded bars are tied to the steel reinforcement frame. The mesh layer is laid inside the frame, and the crushed stone filling layer is laid on the mesh layer and the asphalt filling layer is laid on the crushed stone filling layer. The above device increases the connection strength with the ground by inserting the reinforcement columns with steel reinforcement frames into the ground. However, the single steel reinforcement and reinforcement column inserted into the soil have low compressive strength, and the short concrete column is prone to brittle splitting failure, which cannot effectively reinforce the foundation.

The cone head 14 with the tip of tungsten carbide alloy penetrates into the bearing layer. The reinforcing anchor rod 13 with threaded groove rotates and sinks to generate a reverse locking force. The positioning pipe piles 12 and the reinforcing pipe piles 6 with alternating long and short lengths compress the settlement. The anchor group has high tensile stiffness and can inhibit the creep settlement of soft soil. The flatness of the pre-embedded steel plate 11 can ensure uniform load distribution.

The reinforced base layer 2 is disposed at the bottom of the concrete slab 1. Transverse threaded steel bars 3 are evenly connected in the wall cavity of the concrete slab 1. Longitudinal threaded steel bars 4 are evenly distributed above the transverse threaded steel bars 3. The transverse threaded steel bars 3 pass through the left and right sides of the concrete slab 1, and the longitudinal threaded steel bars 4 pass through the front and rear sides of the concrete slab 1, respectively. A reinforced base plate 5 is disposed on the bottom side of the reinforced base layer 2. Reinforced pipe piles 6 are evenly connected to the bottom side of the reinforced base plate 5. The reinforced pipe pile 6 includes a pipe pile body 15 and a reinforced bottom end cap 16.

When the pipe pile body 15 is under pressure, the reinforcing ribs will convert part of the load into circumferential stress through shear deformation. The cylinder 17 of the reinforced bottom end cap 16 has reserved deformation space to avoid brittle failure of the pile head concrete.

[0030] In summary, with the help of the above-mentioned technical solution of this utility model, when this device is in use, the transverse threaded steel bars 3 and the longitudinal threaded steel bars 4 are stacked one above the other to form an interlaced steel mesh, which can improve the strength of the concrete slab 1.

The installation sleeve 9 and the first reinforcing ring 10 can strengthen and protect the reinforced pipe pile 6. The embedded steel plate 11 is covered inside the soil, and positioning pipe piles 12 are installed between the reinforced pipe piles 6. The embedded steel plate 11 works in coordination with the reinforced pipe piles 6 and the positioning pipe piles 12. The work involves rigidly bonding the pre-embedded steel plate 11 to the bottom of the foundation pit to constrain track misalignment caused by uneven settlement of the foundation. The cone 14 with the tip of tungsten carbide alloy penetrates into the bearing layer. The reinforcing anchor 13 with threaded grooves rotates and sinks to generate a reverse locking force. The positioning pipe piles 12 and reinforcing pipe piles 6 with staggered lengths compress the settlement. The anchor group has high tensile stiffness, which can inhibit creep settlement of soft soil. The flatness of the pre-embedded steel plate 11 is ensured. The reinforcing rib 19 is fully welded to the outer wall of the pipe pile body 15. Epoxy resin grout is injected, and the reinforcing rib 19 and epoxy resin grout form a super-strong composite pile shoe with increased end resistance. When the pipe pile body 15 is under pressure, the reinforcing rib will convert part of the load into circumferential stress through shear deformation.
