This invention discloses a multi-zone controlled heating device for an electrode hot water boiler, relating to the field of electrode hot water boiler technology. It includes a partition and a synchronization assembly. A column is fixed to the top surface of the partition, and a fixing frame is mounted on the outer side of the column. Fixed shielding sleeves are fixedly connected to both ends of the fixing frame, and electrode columns are arranged inside the fixed shielding sleeves. An insulating sleeve is mounted on the top of each electrode column. The synchronization assembly is located in the middle of the partition and includes a protective cover. A protective cover is also mounted on the bottom of the partition. This invention uses a multi-level shielding structure composed of fixed and movable shielding sleeves to achieve graded shielding of the electrode columns. The spacing between the shielding structures increases progressively from bottom to top, gradually increasing the effective conductive exposure area of ​​the electrode columns along the water flow direction. This allows for gradual gradient heating of the electrolyte solution flowing from bottom to top, ensuring the water temperature rises steadily to the set temperature and significantly improving heating uniformity and efficiency.

This utility model provides a prestressed precast roof slab structure for a subway station, comprising: a precast slab and a reinforcing steel assembly. The precast slab consists of a lower slab and an upper slab, with staggered layers formed between the edges of the lower and upper slabs. The reinforcing steel assembly is disposed inside the precast slab and consists of a first longitudinal reinforcing steel bar, a second longitudinal reinforcing steel bar, transverse reinforcing steel bars, vertical reinforcing steel bars, a central reinforcing steel bar, and embedded reinforcing steel bars. This application uses a precast slab and reinforcing steel assembly to construct a precast roof slab structure. By integrally casting the precast slab and arranging multiple longitudinally and transversely distributed reinforcing steel bars inside, its structural strength can be effectively improved. Simultaneously, the arc edges and grooves on the edges of the precast slab facilitate subsequent concrete filling, ensuring the compactness of the precast slab edges. The combination of longitudinal and transverse reinforcing steel bars improves the structural strength of the precast roof slab, and the ends of the reinforcing steel bars are easily fixed with wire, ensuring the stability of the reinforcing steel arrangement and facilitating subsequent concrete pouring, thus improving the performance of the precast roof slab.

This utility model discloses a vibration assembly and a high-frequency vibration curing device for soft soil, relating to the field of vibration compaction technology. It includes: at least one vibrating rod connected in series, each end of which has a matching first internal thread groove and a first external thread section. A first electrode interface, capable of electrical connection through contact, is provided between the bottom of the first internal thread groove and the top of the first external thread section. The first electrode interface is used to rotate a centrifugal rotor inside the vibrating rod. An insulating protective sleeve is connected to the end of the vibrating rod and is used to enclose the first internal thread groove or the first external thread section at the end of the vibrating rod. Using this solution, water and soil can be separated sequentially in the silt layer and soil layer using a specific vibration frequency and arrangement of the vibrating rods, achieving efficient and economical soft soil foundation treatment.
