Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1 to 4, the present invention provides a technical solution: the device comprises an upper structural column 1, a cup-mouth-shaped right circular cone shell 2, a steel pipe 3, a rubber sleeve 4, a grouting hole 5, a steel ring 6 and an inflating nozzle 7. The upper structure column 1 is directly embedded into the cup mouth on the top surface of the cup mouth-shaped right circular cone shell 2, mortar is used for filling the cup mouth, the cup mouth-shaped right circular cone shell 2 and the upper structure column 1 are connected into a whole, the overall stability is improved, five steel pipes 3 with enlarged heads are arranged on the bottom surface of the cup mouth-shaped right circular cone shell 2 in a quincunx shape, and the pulling resistance bearing capacity of the foundation is improved.
The working principle is as follows: when the high-rise building shell foundation with high anti-pulling performance is applied to the foundation, five steel pipes 3 with rubber sleeves 4 at the bottom ends are arranged in a quincunx shape and vertically buried in the bottom surface of a foundation pit, the upper ends of the steel pipes 3 are provided with inflating valves 7 through threads, inflating the steel pipe 3 by high pressure through an inflating nozzle 7 to expand the rubber sleeve 4 at the bottom end of the steel pipe 3, extruding the peripheral soil body, taking down the inflating nozzle 7, grouting the steel pipe 3 by high pressure, enabling the grout to penetrate into the cavity of the expanded rubber sleeve 4 through the plum blossom-shaped hole at the bottom end of the steel pipe to form an expanded head, improving the pulling-resistant bearing capacity of the foundation, then constructing a cup-shaped right circular cone shell 2, connecting the cup-shaped right circular cone shell 2 and the top end of the steel pipe 3 after grouting into a whole, and finally constructing an upper structural column 1, and the cup mouth on the top surface of the cup mouth-shaped right circular cone shell 2 is filled with mortar, so that the upper structure column 1 and the cup mouth-shaped right circular cone shell 2 are connected into a whole.
