The application discloses a method for dividing the end resistance and side friction of a pile foundation in a piling process based on piling records, and the method comprises the following steps: obtaining a curve of the hammering number changing with the depth in the piling process according to the field piling records; obtaining a curve of the relationship between the hammering number and the soil resistance; obtaining a curve of the soil resistance changing with the depth in the piling process by using the two curves; determining the upper and lower envelope lines of the curve of the soil resistance changing with the depth; drawing a straight line through the (0, 0) point and the lowest point of the lower envelope line; obtaining the curve of the soil resistance changing with the depth after eliminating the linear part by subtracting the straight line part from the curve of the soil resistance changing with the depth, and determining the new lower envelope line; fitting the side friction in the piling process by drawing a straight line through the original point, the lowest point and the final point of the new lower envelope line; and obtaining the end resistance of the pile foundation in the piling process by subtracting the side friction from the curve of the soil resistance changing with the depth. The end resistance and the side friction of the pile foundation can be conveniently obtained, and the calculation precision of the pile foundation drivability analysis is improved.

This utility model discloses a wear-resistant carbon fiber composite core cable, relating to the field of cable technology. It includes a cable body and a core, with the core located at the center of the cable body. The core consists of multiple carbon fiber bundles and filler material between the carbon fiber bundles. An inner insulation layer is tightly wrapped around the core, and an outer insulation layer is fitted over the inner insulation layer. A protective layer is then provided on the outside, consisting of a buffer layer, a wear-resistant fiber layer, and a wear-resistant rubber layer, sequentially fitted from the inside out. This utility model significantly improves the wear resistance of the cable, extends its service life, reduces operating costs, and lightens its weight, facilitating installation and laying, by optimizing the cable's structure and materials.

This utility model discloses an online cleaning device for ash accumulation in flue gas ducts, comprising a closed housing. The left side wall of the housing has a through-hole for a front rack and a through-hole for a rear rack. A front rack is also installed inside the housing, extending laterally through the through-hole to the left and out of the housing. A rear rack is also installed inside the housing, extending laterally through the through-hole to the left and out of the housing. A purge grid unit is installed between the front and rear racks, and the purge grid unit can move laterally under the action of the front and rear racks. The device also includes a primary hot air header connected to the purge grid unit. This utility model's device can efficiently move and purge ash accumulation in flue gas ducts, preventing excessive ash buildup. It also effectively reduces the manpower and material resources required for maintenance, reduces safety risks during the operation and maintenance of coal-fired boilers, maintains the combustion efficiency of coal-fired boilers, and is beneficial for energy conservation and environmental protection.

This utility model discloses a dehumidification and drying mechanism with dew point monitoring function, relating to the technical field of dehumidification dryers. It includes a base plate with an upper aluminum disc and a lower aluminum disc respectively, rotatably connected to a honeycomb dehumidification wheel. The rotation of the honeycomb dehumidification wheel is driven by a synchronous belt drive. A dew point transmitter is installed on the upper aluminum disc, with the sensing end extending internally, allowing real-time monitoring of the dew point value of the airflow after drying. The humid airflow passes through the lower aluminum disc into the honeycomb dehumidification wheel, is dried, and then discharged. The synchronous belt drive drives the wheel to rotate via a motor, synchronous pulley, synchronous belt, and toothed plate. A tension adjustment wheel is also provided to adjust the tension of the synchronous belt. This mechanism can provide real-time dew point data, allowing operators to promptly grasp the dehumidification performance of the equipment, ensuring safe plastic molding operations, reducing resource waste, and improving production efficiency and product quality.
