Minitype friction short tubular pile composite foundation structure and constructing method thereof
The invention discloses a minitype friction short tubular pile composite foundation structure and a constructing method thereof. Cement concrete is poured into tubular geotextile, the diameter of which is 10cm, to form a tube embryo, the length of which is 4-5m, the tube embryo is maintained and hardened to form a geotextile-cement concrete tubular pile body (1), the thickness of the geotextile-cement concrete tubular pile body (1) is larger than 1cm, the cross-section compressive strength of the geotextile-cement concrete tubular pile body (1) is higher than 20Mpa, and the geotextile-cement concrete tubular pile body (1) is pressed into a soft foundation, concrete mortar is poured into the pipe hole of the geotextile-cement concrete tubular pile body (1) which is pressed in position, then the concrete mortar is extruded out of the lower pipe orifice of the geotextile-cement concrete tubular pile body (1), and a perfusion tubular pile expanded-foot (2) is formed, the upper pipe orifice of the geotextile-cement concrete tubular pile body (1) is provided with a tubular pile top (3), the tubular pile top (3) is provided with a tubular pile cap (4), and geogrids (5) and filling sand cushions (6) are laid on the tubular pile cap (4) in a layered and alternative manner. The minitype friction short tubular pile composite foundation structure is low in cost, simple to construct, fast in construction speed and good in environmental protection property.
