Drawings
Fig. 1 is a schematic structural diagram of a part of a pile foundation underpinning structure according to an embodiment of the present invention.
In the figure, 1, pile foundation; 2. a bearing platform; 3. a jack; 4. supporting and replacing the plate; 5. a cambered surface; 6. a groove; 7. a rubber pad; 8. anchoring ribs; 9. brick walls; 10. a pipe trench; 11. an opening; 12. a pipe trench cover plate; 13. sand; 14. a natural gas pipeline.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, for the utility model discloses a pile foundation underpins structure, including pile foundation 1, anchor muscle 8, cushion cap 2, jack 3 and underpinning board 4, pile foundation 1 and ground fixed connection, pile foundation 1 forms through pouring. Cushion cap 2 passes through anchor muscle 8 and pile foundation 1 fixed connection, and anchor muscle 8 penetrates pile foundation 1 to cushion cap 2 is comparatively stable with being connected of pile foundation 1. The bearing platform 2 is also formed by pouring, a groove 6 is formed in the top end of the bearing platform 2, and the jack 3 is arranged inside the groove 6. The top of jack 3 and underpinning board 4 fixed connection, underpinning board 4 is the arc, and underpinning board 4 has the cambered surface 5 that is used for bearing natural gas line 14. After the ground subsides, jack 3 will ask to trade the natural gas line 14 jack-up on board 4 and the underpinning board 4 to natural gas line 14 still can keep at original height, and this pile foundation underpins structure still can support natural gas line 14 after the ground subsides.
Preferably, as shown in fig. 1, the pile foundation underpinning structure further comprises a rubber pad 7, the rubber pad 7 is arranged on the cambered surface 5, and the rubber pad 7 and the cambered surface 5 can be adhered through bonding. When the natural gas pipeline 14 is placed on the underpinning plate 4, the rubber pads 7 increase the friction force between the natural gas pipeline 14 and the underpinning plate 4, so that the natural gas pipeline 14 is placed on the underpinning plate 4 more stably and is not easy to deviate.
Finally, as shown in fig. 1, brick walls 9 are laid on both sides of the bearing platform 2, and the brick walls 9 on both sides of the bearing platform 2 and the bearing platform 2 form a pipe trench 10 for accommodating a natural gas pipeline 14.
