The utility model relates to the technical field of sulphur recovery equipment, specifically a floating ball type sulphur sealing device, including inner cylinder, the inner cylinder top part sets up cylinder top flange cover, the inner cylinder bottom part sets up cylinder bottom flange cover, the inner cylinder connects liquid sulphur inlet inner connector and liquid sulphur outlet inner connector respectively, the liquid sulphur outlet inner connector extends into the inside of inner cylinder, the liquid sulphur outlet inner connector extends into the inside of inner cylinder one end upper portion opening, and opening place fixedly connected with the communicating port, the communicating port is in communication with liquid sulphur outlet inner connector, the communicating port is slidably connected with the plunger, and the plunger can block the communicating port, and the top of plunger is fixedly connected with the floating ball. The utility model discloses a floating ball type sulphur sealing device simple structure, through the floating ball drive plunger isolation process gas into liquid sulphur storage facility, and ensure that the liquid sulphur generated flows into the storage facility, eliminates the hidden danger of safety while saving the investment, and is more favorable to the maintenance of equipment.

The utility model relates to a water-adjacent piling platform, belongs to piling construction technical field, specifically is a kind of water-adjacent piling platform of steel pipe erection, including patterned steel plate, still include support assembly;Steel casing, the steel casing is installed on patterned steel plate, shock-absorbing rubber plate is fixedly installed between the steel casing and patterned steel plate;The utility model reaches the effect of low cost, erects, removes fast, construction cycle is short, does not destroy riverway environment, solves the problems, such as high construction material cost of existing patent, multiple steel casing is needed, and additional piling and pulling pile operation are increased, greater influence is caused to surrounding environment and sensitive structure, construction cost and construction time are greatly increased.

This utility model discloses a phosphogypsum drying oven arch and drying oven. The arch includes an arch body with an inner surface layer and an outer surface layer on both sides. The arch body includes a steel reinforcement frame in a mesh structure and a first insulation layer formed within the mesh. This utility model uses a steel reinforcement frame and a lightweight insulation layer (rock wool insulation material), which greatly reduces the overall weight of the arch. The reduced weight lowers the load-bearing pressure on the drying oven foundation, thereby reducing the cost and workload of foundation construction. At the same time, the lighter arch is more convenient to install and transport, reducing construction difficulty and related costs.

The application discloses a main bridge steel structure construction method and relates to the technical field of bridge construction. The specific steps comprise the following steps: dividing regions, installing baffle plates and pier columns, installing steel pipe piles and platform support columns, installing inter-column supports and sliding beams to form sliding tracks, repeatedly constructing the south bank, completing platform support covering a river, installing lower chord rods and lower bridge decks, installing upper chord rods and upper bridge decks, installing upper-layer cantilevers and lower-layer cantilevers, assembling sliding units, repeatedly assembling sliding units until closure, hoisting the last sliding unit and completing installation of the main bridge steel structure. The construction method can reduce operation risks, shorten construction period, save materials and reduce costs.

This utility model discloses a drainage structure for construction joints in subway stations, belonging to the field of subway station construction technology. It includes a drainage pre-reserved groove located at the construction joint of the main structure. A water-stop steel plate is tightly attached to one side wall of the drainage pre-reserved groove. A drainage pipe is placed inside the drainage pre-reserved groove, and a filling material is placed between the drainage pipe and the bottom of the drainage pre-reserved groove. Permeable concrete is filled above the drainage pipe in the drainage pre-reserved groove. This utility model effectively prevents the drainage pipe holes from being blocked by wrapping the surface of the drainage pipe with non-woven permeable geotextile and dense wire mesh. Covering the drainage pipe with permeable concrete and ensuring the water-stop steel plate is tightly attached to the drainage groove effectively allows water in the main structure to collect in the drainage pipe through the highly permeable concrete and then be discharged through the drainage pipe. This utility model structure avoids the need for secondary trenching for drainage when leakage occurs in the subway station, ensuring the integrity of the main structure and saving subsequent construction costs.
