This invention relates to a mixing device for nitrile glove mold raw materials, comprising a shell, a liquid inlet at the upper left end of the shell, a solid inlet at the upper right end of the shell, a mixing drum at the lower end of the shell, a vibration component at the bottom of the mixing drum, a drive shaft in the middle of the mixing drum, puncture-type paddles evenly arranged in the middle of the drive shaft, angled paddles located below the puncture-type paddles on the drive shaft, and an outlet at the lower end of the shell. This invention solves the problems of existing mixing methods, which are typically unidirectional, making it difficult to quickly and effectively mix raw materials, and resulting in uneven mixing of raw materials in the peripheral areas during the mixing process. Furthermore, the mixing process generates air bubbles, which cause voids inside and on the surface of the solidified mixture.

This invention provides a method for constructing retaining piles for a deep foundation pit within a pit, comprising the following steps: determining several sets of construction sequence groups by surveying the location of the retaining piles within the pit; for the preceding construction groups, excavating guide trenches and installing casings according to the construction sequence; constructing pile holes sequentially according to the construction sequence; each pile hole includes an empty drill section and an effective pile length section; connecting a simple hoist cage to a reinforcing cage at the bottom, lowering the simple hoist cage and reinforcing cage into the pile hole, with the top of the simple hoist cage connected to the pile hole opening; lowering a grouting pipe to pour underwater concrete to the top of the effective pile length section, and filling the empty drill section with fluidized solidified soil to the ground elevation; repeating steps 2-5 to construct the subsequent construction groups, forming the retaining piles within the pit; after the concrete has cured to the required standard, excavating the deep foundation pit and constructing the pit within the pit; and constructing a water-stop curtain on the outside of the retaining piles within the pit. This invention relates to the field of building construction technology and can solve the problems of high cost of backfilling empty drill sections with plain concrete and the easy cross-hole problems of backfilling empty drill sections with plain soil or yellow sand in the prior art.

This utility model relates to the field of knives, specifically a kitchen knife, comprising a blade, a cutting edge, a handle, and welded end faces. The blade is welded to the bottom of the blade, and welded end faces are provided at the interface between the blade and the cutting edge. The handle is connected to the side of the blade by screws. Two different materials are joined together by welding; this method saves costs, allowing the upper part to use ordinary materials while the lower part can use high-quality materials, controlling costs and improving product quality without compromising quality. The two materials can be heat-treated separately to ensure optimal performance for both.
