Device for improving vertical bearing capacity of pipe pile in sandy soil layer
The invention relates to the technical field of building construction, in particular to a device for improving the vertical bearing capacity of a pipe pile in a sandy soil layer, which is characterized in that a cross-shaped fastener and a vertical guide pipe are arranged in a guide main pipe, a water flow conveying pipe and a water flow washing pipe are arranged in the cross-shaped fastener, and a sediment conveying pipe is arranged in the vertical guide pipe; the arc-shaped fixing piece is fixed on the vertical guide pipe; the device has the beneficial effects that the water flow conveying pipe and the water flow flushing pipe are connected to the high-pressure water pump, the sediment conveying pipe is connected to the mud pump, the high-pressure water pump is started, sediment at the bottom of the pipe column is scattered and diluted, meanwhile, the mud pump is started, and the diluted sediment is pumped out through the sediment conveying pipe; and when the pipe column is settled to a proper depth, slurry is injected into the bottom of the pipe column through the silt conveying pipe, so that the slurry is solidified at the bottom of the pipe column, and the vertical bearing capacity of the pipe column in the sandy soil layer is improved.
本发明涉及建筑施工技术领域，具体为一种提高管桩在砂性土层中竖向承载力的装置，包括：导向主管的内部设有十字紧固件和竖向导管，十字紧固件的内设有水流输送管和水流冲刷管，竖向导管的内部设有泥沙输送管；弧形固件固定于竖向导管上；有益效果为：通过将水流输送管和水流冲刷管连接于高压水泵，泥沙输送管连接于泥浆泵，通过启动高压水泵，使得管柱底部的泥沙被冲散和稀释，同时启动泥浆泵，将稀释的泥沙通过泥沙输送管进行抽出，由此便于管柱在砂性土层中进行沉桩，管柱沉淀到合适的深度时，通过泥沙输送管向管柱底部注入泥浆，使得泥浆在管柱底部进行凝固，由此提高管柱在砂性土层中的竖向承载力。
