[0002] The foundation refers to the soil or rock that supports the base of a building, that is, the part of the soil that bears the load of the superstructure. It plays a very important role in ensuring the strength and durability of the building.

[0003] When the foundation conditions are poor and the soil is relatively soft, the supporting force for the superstructure is often poor, which will bring greater danger to the superstructure. Therefore, it is necessary to artificially reinforce the soft soil foundation. Among them, driving reinforcement pipes into the foundation is one of the commonly used reinforcement methods.

[0004] The existing reinforcement pipe is a simple cylindrical shape, and its reinforcement effect on the foundation is limited. After being hammered into the foundation, the reinforcement pipe cannot be well fixed in the foundation, and the use effect is not good, which needs to be improved. Utility Model Content

[0023] In this embodiment: when in use, the base column 1 is first hammered into the foundation, and the base column 1 squeezes and reinforces the soil in the foundation. Then, the threaded rod 4 is rotated by the hexagonal bolt head 10. By setting the thread directions of the upper and lower ends of the threaded rod 4 to be opposite, when the threaded rod 4 is rotated, the two threaded sleeves 5 are driven to move relative to each other, and then the slider 3 is driven to slide outward along the slide groove 2 through the connecting rod 6.
