Grouting screw pile for marine soft soil foundation
The invention relates to the technical field of pile foundation construction, in particular to a grouting screw pile for a marine facies soft soil foundation, and provides the grouting screw pile for the marine facies soft soil foundation aiming at solving the problem that an existing grouting screw pile has certain loosening, sinking or upward moving risks when an electric tower is installed after the existing grouting screw pile is driven into the ground. The pile body is hollow, a pointed cone is arranged at the bottom of the pile body, and a plurality of spiral pieces are arranged on the outer surface of the pile body. A rotatable driving seat is arranged at the upper end of the pile body, a plurality of reinforcing devices are arranged in the pile body, each reinforcing device comprises a plurality of arc-shaped push plates which are uniformly distributed, L-shaped push plates are arranged on the two sides of each arc-shaped push plate respectively, and when the driving seat rotates, a structure that the pile body enters the interior of the land can be formed; the stability of the grouting type screw pile can be further improved, the grouting type screw pile is prevented from loosening, sinking or moving upwards when an electric tower is installed, safe operation is improved, and the service life is prolonged.
本发明涉及桩基施工技术领域，尤其是涉及一种用于海相软土地基的注浆螺旋桩，针对现有的注浆式螺旋桩，在打入地下后安装电塔时，还具有一定的松动、下沉或上移风险，提供一种用于海相软土地基的注浆螺旋桩，包括桩体，所述桩体内部为中空状，桩体底部设有尖锥，桩体外表面上设有多个螺旋片；桩体上端设有可转动的驱动座，桩体内部设有多个加固装置，加固装置包括多个分布均匀的弧形推板，弧形推板两侧分别设有L形推板，所述驱动座转动时可构成桩体进入土地内部的结构；能够进一步提高注浆式螺旋桩的稳定性，在安装电塔时防止注浆式螺旋桩松动、下沉或上移，提高安全操作、延长使用寿命。
