Traversing construction method for tie bar arch

Номер: CN0102251477A
Принадлежит:

The invention discloses a traversing construction method for a tie bar arch, and relates to a bridge construction process. A main pier, a temporary pier and the tie bar arch are adopted in the method, wherein the span of the tie bar arch is 54 to 74 meters. The traversing method comprises the following steps of: 1, arranging a counterforce pier; 2, arranging an upper slipway and a lower slipway; 3, arranging and installing a jack; 4, arranging a stay wire type sensor; 5, traversing; and 6, jacking and lowering beams. By the method, the construction period is shortened, daily maintenance cost can be saved, the detached tie bar arch can be reused so as to save engineering investment to a great extent, and the method is high in safety.

Temperature-raising method and system for coke dry quenching furnace

Номер: CN104031662A
Принадлежит:

The invention relates to the technical field of energy recovery and discloses a temperature-raising method and a temperature-raising system for a coke dry quenching furnace. The method comprises the steps of laying cold coke from the bottom of the coke dry quenching furnace to a position higher than the top of the chute zone of the coke dry quenching furnace; putting hot coke on cold coke from the position above cold coke; carrying out coke discharging on coke dry quenching furnace, and introducing the circulating air; and controlling the coke discharging speed and/or air speed and/or air quantity of the introduced circulating air according to the temperature of the circulating air required for heat exchange. By virtue of the method disclosed by the invention, cold coke in the coke dry quenching furnace is slowly heated, the direct contact between the chute zone of the coke dry quenching furnace and high-temperature hot coke is avoided, the degree of change of the thermal stress is reduced ...

Method for treating coking and biochemical sludge

Номер: CN104341087A
Принадлежит:

The invention discloses a method for treating coking and biochemical sludge and belongs to the technical field of resource recycling and reusing. The method comprises the following steps of concentrating the residual sludge discharged from a backflow sedimentation tank and a secondary sedimentation tank; delivering the concentrated sludge into a sewage well to prevent the sludge from being hardened; collecting environment dust-removing dust; spraying the sludge to the environment dust-removing dust to humidify the environment dust-removing dust; delivering the sprayed and humidified environment dust-removing dust to a coal preparation belt. By the method for treating the coking and biochemical sludge, the problem that the biochemical sludge is difficultly treated is solved.
