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 relates to the technical field of bridge design and construction, and provides a structure beneficial to hollow slab hinge joint pouring and shear connection. The hinge joints are formed by a plurality of hollow slabs at certain intervals in the width direction. The hinge joint distance of a traditional hollow slab is increased, the hinge joint participates in shear resistance within the full height range, the U-shaped steel plate is arranged at the position of the bottom plate of the hollow slab, and the steel plate is squeezed into a notch reserved in the bottom plate through elasticity of the steel plate to serve as a bottom die for pouring hinge joint concrete and plays a role of a dripping eave in the operation period. Shear-resistant assemblies which are arranged in a staggered mode are embedded in webs, facing the hinge joints, of the hollow slabs, and each shear-resistant assembly is composed of a perforated steel plate embedded in the corresponding hollow slab, a connecting steel plate and an outwards-extending shear nail. By means of the measures, the shear-resistant area, the pouring quality, the shear-resistant strength and the attractiveness of the hollow slab hinge joint are improved; the technical problems that in the prior art, a gap of only 1 cm exists between every two adjacent hollow plate bottom plates, hinge joint concrete is difficult to pour, the connection strength is poor, and water seepage is prone to occurring are solved.

The invention discloses an anti-slip multi-stage drop culvert, comprising a hollow culvert body, wherein the outer top and outer bottom of the culvert body are both stepped, and a plurality of drop steps are arranged on the inner bottom surface of the culvert body along the water flow direction, and an inclined energy-absorbing steep slope is arranged on the step surface of the drop steps. By arranging the outer top and outer bottom of the culvert body in a stepped shape, the weight of the culvert body acts on the soil below it in a vertical direction, and the covering soil is positively pressed on the top of the culvert body, so that the culvert body and the top covering soil can be effectively prevented from slipping without additionally arranging anti-slip support facilities. At the same time, the water flow is impacted and energy-dissipated by the drop steps and the energy-absorbing steep slope inside the culvert body, and the water flow is further energy-dissipated in cooperation with the energy-reducing protrusions on the inner side of the culvert body, so that the water flow speed can be effectively slowed down without additionally arranging energy-dissipating facilities.

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.

The utility model relates to the technical field of injection molding equipment, in particular to a material taking jig for an injection molding machine, which comprises a fixing frame, a clamping mechanism and a first material taking mechanism connected with one side of the fixing frame, one end of the fixing frame is used for being connected with external mobile equipment, the other end of the fixing frame is connected with the clamping mechanism, and the clamping mechanism is used for clamping a workpiece; the first material taking mechanism comprises a first push plate, a plurality of first push rods and a first driving part fixedly connected with the fixing frame, the first driving part is in driving connection with the first push plate, one end of each first push rod is connected with the first push plate, and the other end of each first push rod is provided with a first material taking part used for conveying nuts; the first driving piece is used for driving the first material taking piece to move into the injection molding machine mold cavity and pushing the nut into the injection molding machine mold cavity. The material taking jig is small in occupied area, a plurality of nuts can be pre-embedded at the same time, the clamping mechanism can quickly take workpieces subjected to injection molding before the nuts are pre-embedded, and efficiency is improved.
