The present application relates to a kind of preparation methods of gypsum keel, the method is in the scheduling, monitoring of joint operation center with two production lines according to different technical routes to produce the gypsum keel of same quality.Solve the problem of the easy rust corrosion of light steel keel, steel plate rib web, the difficulty of marking bar, the insufficient strength, pressure resistance and impact resistance of column body in the spray construction type composite wall.

The present application relates to an array electrode intelligent sensing system for tunnel gushing water monitoring and a method thereof. The system comprises a flexible sensing array implanted inside or on the surface of a tunnel lining structure, an intelligent acquisition node and a data analysis platform. The flexible sensing array is composed of multiple composite sensing units arranged in a predetermined topological structure, each unit integrating a main electrode for measuring resistivity / potential, a temperature sensor for measuring temperature and a flexible strain sensor for measuring deformation; the intelligent acquisition node connects the sensing array to synchronously acquire resistivity, temperature and strain data in multiple channels, and preliminarily processes and extracts features from the original data; the data analysis platform receives data from multiple nodes, and through a multi-parameter spatio-temporal fusion analysis model, realizes the collaborative intelligent analysis from "water-bearing state perception" to "structure deterioration evaluation" to "gushing water risk early warning". The present application realizes the fine, three-dimensional and real-time monitoring of the incubation process of tunnel water disasters.

The utility model discloses an adjustable electric box precast block mould, including the placing cavity, the both ends of placing cavity two sides respectively are provided with a group of first connecting barrel, the both ends of placing cavity two sides respectively are provided with a group of second connecting barrel, second connecting barrel and first connecting barrel swing joint, the outside of placing cavity is provided with the telescopic structure for adjusting the size of mould. This adjustable electric box precast block mould is provided with first baffle, and the electric box precast block mould can respectively pull each group first connecting barrel and second connecting barrel to drive first baffle and second baffle to move in use, adjusts first connecting barrel and second connecting barrel to the appropriate interval, to adapt to the electric box of different size, and the limit rod is pasted in the inside of limit cylinder can be positioned to first connecting barrel and second connecting barrel, to improve the rigidity of this structure whole, prevents the deformation when construction, solves the problem of unable quick regulation size.
