Cement mixing pile structure reinforced through geosynthetic materials and construction method thereof

The invention discloses a cement mixing pile structure reinforced through geosynthetic materials and a construction method of the cement mixing pile structure reinforced through the geosynthetic materials. A cement mixing pile is a cement-reinforced soil pile formed by forcedly mixing cement and in-situ soil at a foundation deep layer on the spot. The cement mixing pile structure is characterized in that reinforcement bodies made of the geosynthetic materials are arranged in the cement mixing pile to form reinforced structures. The construction method comprises the steps of (1), constructing all cement mixing piles one by one through cement mixing pile forming equipment on a cleaned and flattened soft soil foundation according to pile positions which are determined by measurement; (2), hitting the reinforcement bodies made of the geosynthetic materials into cemented soil of the cement mixing piles at the initial setting time of the cemented soil obtained after construction of each cement mixing pile; and (3), carrying out quality detection on the cement mixing piles according to standard requirements after 28 days. The cement mixing pile structure is reasonable in design, reliable in material, mature and simple in process, easy to construct, convenient to operate, low in cost, easy to popularize and suitable for reinforcement of soft soil foundations of water conservancy and waterway construction projects such as channels, dikes and water gates in soft soil areas.
