This utility model relates to a detachable pile foundation rebar cage assembly frame suitable for construction in steep slope areas. It includes a base, characterized by: a lower column and an upper column above the base; a lower horizontal bar and a middle horizontal bar between the lower columns; an upper horizontal bar at the top of the upper column; a lower diagonal bar between the lower column and the middle horizontal bar; an upper diagonal bar between the upper column and the upper horizontal bar; a lower hanging beam at the top of the middle horizontal bar; an upper hanging beam at the top of the upper horizontal bar; and chucks on the inner sides of the lower and middle horizontal bars. Compared with existing technologies, the core value of this utility model lies in achieving on-site assembly of the rebar cage without large-scale earthwork and large platforms / equipment, thereby reducing costs, protecting slope stability, ensuring construction safety, and significantly improving the feasibility of construction under such complex terrain conditions. It provides a practical, safe, and economical solution for pile foundation rebar cage construction in steep slope areas where traditional methods are difficult to implement or are too costly / risky.

The application relates to the technical field of intelligent diagnosis of power supply systems and optical communication cross technology, and discloses a power supply system health diagnosis method based on adaptive multi-dimensional ripple feature fusion, which comprises the following steps: short-time coarse sampling of a power supply ripple signal, dynamic adjustment of sampling parameters and window function types according to the coarse sampling result; extraction of frequency domain features, time domain features and time-frequency domain features to form a multi-dimensional feature vector; dynamic updating of a fault threshold value through Bayesian estimation based on historical normal feature samples in a fault feature sample library; adoption of weighted D-S evidence fusion of the fault confidence of the multi-dimensional feature vector based on the fault threshold value, and determination of a system state based on the fault confidence to output a diagnosis result; and hierarchical fault tracing when the system state is an abnormal state. The application realizes adaptive sampling and feature fusion, reduces the fault misjudgment rate, shortens the tracing time consumption, has low computing power consumption, and is suitable for real-time health diagnosis of a data center optical module power supply system.

The utility model relates to a kind of installation tolerance regulators of automobile outer door handle, including assembly shell structure and multiple movable installation limiting components, assembly shell structure includes main connection shell, limiting handle corresponding slot area, multiple equidivided installation sleeve structure, movable installation limiting component includes mounting spiral sleeve structure and assembly adjusting bolt body, mounting spiral sleeve structure includes spiral sleeve body, spiral body being arranged on the outer surface of spiral sleeve body, limiting clamping groove, built-in limiting structure being arranged in spiral sleeve body, the assembly adjusting bolt body includes lock nut and nut and threaded body.The positioning structure of the installation tolerance regulator configuration is relatively simple, corresponding adaptability is strong, there may be size or space difference and low structural rigidity in multiple screwing components, locking firmness is poor, the two components of the body reduce forced misregistration after mounting screw locking, cause the two components of the body in Y direction stress opposite, cause partial torsion.

The invention provides a preparation and ecological restoration method of alkali-resistant plant-growing cement soil based on a compound microbial agent, and relates to the technical field of plant-growing cement soil. The compound microbial agent is prepared by synergistic propagation of arbuscular mycorrhizal fungi and dark partitioned endophytic fungi domesticated in an alkaline environment; and a trehalose-soluble starch composite protective agent is adopted to improve the activity and stability of the microbial inoculum through a vacuum freeze-drying process. The microbial agent disclosed by the invention has good environmental adaptability, can effectively promote root development, nutrient absorption and drought resistance of plants in plant-growing cement soil, and remarkably improves the survival rate and sustainability of slope ecological restoration. The method is simple in process, low in cost, green, environment-friendly and suitable for large-scale popularization and application.
