The application discloses a foundation pit support structure with a cup mouth with a sloping top surface, comprising inner-row precast piles and outer-row precast piles, the top surface of the inner-row precast piles being lower than that of the outer-row precast piles, and the top portions of the two rows of precast piles being inclined soil layer slopes; the top portions of the two rows of precast piles are each provided with an equal-height precast composite beam, the upper side of the soil layer slope is formed by pouring fine stone concrete to form a post-poured slope top surface layer, and the post-poured slope top surface layer is formed together with a post-poured composite part of the precast composite beam; the side of the two adjacent inner-row precast piles facing the inside of the foundation pit is provided with a truss-rib composite slab, and the pile bodies are filled with high-strength grouting material by high-pressure grouting and are solidified to form post-poured shear walls; the post-poured slope top surface layer, the truss-rib composite slab and the post-poured shear walls are all provided with anchor rods, and all the anchor rods are obliquely punched into the soil layer outside the foundation pit. The application also realizes a construction method of the support structure, can effectively control the deformation of the foundation pit, improves the overall stability and bearing capacity of the support structure, and is safe and reliable in construction.

This invention relates to the field of seismic isolation and vibration reduction engineering technology, and discloses a friction pendulum bearing capable of resisting uplift forces. This friction pendulum bearing includes a liner unit, a support unit, a reset unit, and a limiting unit. The liner unit includes a steel ball-shaped liner and pressure-bearing sliding plates symmetrically arranged on the upper and lower sidewalls of the steel ball-shaped liner. The support unit includes an upper support and a lower support arranged opposite to each other, and retaining ring assemblies arranged on the opposite sidewalls of the upper and lower supports. The reset unit includes flange plates respectively arranged on the sidewalls of the upper and lower supports and a reset member connecting the opposite flange plates. The friction pendulum bearing of this invention dissipates seismic energy through the conversion of kinetic energy, potential energy, and thermal energy during frictional sliding. It has a compact overall structure, high load-bearing capacity, and can reliably withstand and transmit forces when the superstructure of a bridge or building generates forces in different directions, ensuring that it can resist uplift forces regardless of displacement in any direction.

The application relates to the field of vehicle transmission technology and discloses a non-integer multiple magnetic pole proportion and wedge-shaped magnet magnetic force circulating hub system which comprises a bearing seat, a hub assembly, a wheel rim assembly, a first bearing group and a second bearing group. The bearing seat is fixedly connected with a vehicle suspension or a steering knuckle. The hub assembly is rotationally connected between the first bearing group and the bearing seat, the wheel rim assembly is rotationally connected between the second bearing group and the bearing seat, and the wheel rim assembly is coaxially arranged with the hub assembly. A first permanent magnet array is arranged on the hub assembly, and a second permanent magnet array is arranged on the wheel rim assembly. The first permanent magnet array and the second permanent magnet array are arranged between the hub assembly and the wheel rim assembly to form a magnetic field coupling, non-contact power transmission is realized, contact wear and lubrication dependence in traditional mechanical transmission are avoided, transmission efficiency is improved, and the service life of the system is prolonged.
