This invention relates to the field of garment care devices, specifically providing a trouser crease care device. It aims to solve the problem that existing clamp-type garment care cabinets often cannot accommodate trousers of different lengths, resulting in poor crease formation on trousers that are not properly compressed. To this end, the trouser crease care device of this invention includes a support frame, an upper hanging rod, and a lower hanging rod assembly. The upper hanging rod is connected to the upper end of the support frame and extends horizontally. The lower hanging rod assembly is movably connected to the lower end of the support frame and is configured to clamp the lower end of the trousers and pull it away from the upper hanging rod, thus tightening the trousers. Through this configuration, the trouser crease care device can accommodate trousers of different lengths and, through the upper and lower hanging rod assemblies, tightens folded trousers, thus forming a good crease.

The present application relates to a kind of new type of wall protection mud material for ultra-deep underground continuous wall and its preparation method, comprising the following steps: pour mixing water into the first container, while adding bentonite, the first container is stirred to be uniformly dispersed;Sodium carbonate, sodium carboxymethyl cellulose, xanthan gum and silicone acrylic emulsion are mixed and added to mixing water and poured into the second container, and stirred to be fully hydrated;Mix the solution in the first container and the second container, stir to be fully mixed, complete mud preparation.The beneficial effects of the present application are: it can avoid the hidden troubles such as excessive lateral earth pressure, large amount of mud loss, thin and dense mud skin cannot be formed when the excavation depth of underground continuous wall is large, configure a new type of modified bentonite wall protection mud with suitable physical stability and chemical stability, appropriate relative density, good mud skin forming property, which can adapt to the working condition of ultra-deep underground continuous wall, avoid the occurrence of hole collapse and shrinkage phenomenon, so as to ensure the quality of slotting and construction safety.
