[0002] During the construction process, the ground surface needs to be solidified to increase the stability of the upper buildings. Loose foundation soil will reduce its bearing capacity, causing building settlement and structural damage, which will not only increase the difficulty of construction, but also cause greater safety hazards. Therefore, it is necessary to strengthen the foundation before construction to reduce the probability of the above situation. In traditional reinforcement technology, vibration, impact or water flushing are used to make holes in the foundation, and crushed stone or sand and gravel are filled to form a dense pile body, which forms a composite foundation with the original foundation soil to enhance the foundation strength. However, the structure of crushed stone or sand and gravel is loose and the strength is low. If the water content in the soil is high, a large amount of water will overflow during the vibration process, affecting the construction quality. Water overflows on the ground, causing the ground soil to be muddy, affecting the subsequent ground hardening construction. Summary of the invention
