Detailed Description

To explain technical contents, structural features, and objects and effects of the technical solutions in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.

Referring to fig. 1, 2 and 3, the present invention provides a composite foundation structure of a single-pile bearing platform of a communication three-pipe tower, which includes a bearing platform 1 and a pile body 2 disposed under a ground 5. The bearing platform is arranged above the pile body, the upper bearing platform is used for anchoring the foundation anchor bolts of the three-pipe tower, the lower pile body is used for enhancing the bending resistance, shearing resistance and tensile strength of the foundation structure of the three-pipe tower, and the composite foundation formed by the upper bearing platform and the lower pile body jointly bears the pressure, shearing force and bending moment of the three-pipe tower simplified to the plane centroid of the tower foot.

The pile longitudinal ribs 21 are arranged in the pile body, the pile longitudinal ribs protrude out of the upper end face of the pile body, and the pile longitudinal ribs protruding out of the upper end face of the pile body are anchored into the bearing platform to enhance the connection strength between the pile body and the bearing platform. In this embodiment, the cushion cap and the pile body can be irrigated twice, which can effectively reduce the construction difficulty.

Bearing platform upper surface upwards extends and is provided with three basic column cap 11, and high setting such as three basic column cap, the setting of the outstanding ground of basic column cap is convenient for directly build the tee pipe tower subaerial, connects each column foot of single-pipe tower in the basic column cap department that corresponds, be provided with rag anchor 12 in the basic column cap, and the outstanding basic column overhead end setting of rag anchor, rag anchor when watering the basic column cap on bearing platform and the bearing platform, pre-buried advance in basic column cap and the bearing platform. The number of anchor bolts sets up to a plurality ofly, and anchor bolts passes through the stirrup of putting more energy into and connects.
