Embodiment Construction
[0015] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:
[0016] Such as Figure 1~2 Shown, the present invention mainly comprises pile body main body and reinforced skeleton, and pile body main body is hollow nail-like structure, comprises pile cap 1, pile rod 2 and pile head 3, pile cap 1, pile rod 2 and pile head 3 from top to bottom connected in sequence.
[0017] There are several grouting pipes 5 inside the main body of the pile. The grouting equipment injects grout into the soil around the reinforced frame through the grouting pipes 5. These grouts form the foundation enlarged feet together with the reinforced frame to ensure the bearing capacity of the structural foundation and the ability to resist overturning. .
[0018] The pile head 3 is a tapered structure, and the cross section of the pile head 3 gradually becomes smaller from top to bottom, so that the pile head 3 is easier to drive into the ...

The invention relates to a pile foundation structure, in particular to an inverted umbrella-shaped pile foundation structure, and belongs to the technical field of a building structure. The inverted umbrella-shaped pile foundation structure comprises a pile body main body and a strengthening framework, wherein a plurality of grouting pipes are arranged in the pile body main body; the side wall of a pile rod is provided with a propulsion groove which runs through in left-right direction; the strengthening framework comprises a movable groove block, short rods, long rods, a fixed groove block and a propulsion rack; the fixed groove block is fixedly arranged at the bottom end of the pile rod; the inner side of the movable groove block is connected with the propulsion rack; the propulsion rack is arranged in the propulsion groove in a sliding manner; the outer surface of the movable groove block is hinged with a plurality of short rods; the lower end of each short rod is hinged with a correspondingly arranged long rod; the outer surface of the fixed groove block is hinged with a plurality of long rods which correspond to the short rods one to one. The existing cast-in-place reinforced concrete structure is optimized to be a prefabricated inverted umbrella-shaped pile foundation structure, modularized production can be realized, concrete curing is not required, the engineering period can be greatly shortened, and the product quality can be guaranteed.
Description
technical field [0001] The invention relates to a pile foundation structure, specifically an inverted umbrella-shaped pile foundation structure, which belongs to the technical field of building structures. Background technique [0002] At present, municipal roads are equipped with street lighting and traffic guidance facilities in order to keep the city smooth. These facilities can reach a height of 10-20 meters. They are structures with relatively small vertical loads and large bending moments caused by horizontal loads. They require high anti-overturning capabilities, especially in areas with large wind loads such as coastal areas and mountainous areas. [0003] At present, the foundations of these facilities generally use cast-in-place reinforced concrete independent foundations. In order to meet the anti-overturning requirements, the foundations are generally buried at a depth of 3 to 4 meters. The commonly used construction method is reverse excavation after the road pa...
