The invention provides a construction method for replacing deck longitudinal beams of an upper edge cabinet of a bulk cargo ship. The construction method for replacing the deck longitudinal beams of the upper edge cabinet of the bulk cargo ship comprises the following steps that transverse reinforcing plates are welded to a main deck corresponding to the upper edge cabinet at intervals; ventilation technological holes are formed in the positions, close to a cargo hold cover, of the main deck; shuffling technological holes are formed in the positions, close to the sides of the ship, of the main deck; a scaffold is erected in the upper edge cabinet, and a storage platform is built in the upper edge cabinet; a plurality of protection split heads are welded along the deck longitudinal beams at intervals; the first deck longitudinal beam is cut, transferred onto the storage platform after falling onto the split heads, and then cut according to the required length, and longitudinal beam sections are hoisted out of a cargo hold through a hoisting device; the rest of the deck longitudinal beams are cut sequentially into sections to be transferred out of the cargo hold; new deck longitudinal beams are hoisted into the cargo hold to be assembled, positioned and welded; and after construction is completed, auxiliary facilities are cut and dismantled, and the technological holes are filled. By the adoption of the construction method, the large-length single longitudinal beam sections can be transferred out of the cargo hold, and the problem that a ship body possibly deforms in the construction process is solved.

The invention discloses a novel adsorption suppository for a woman. The suppository comprises a nonwoven fabric layer, a carbon fiber felt fabric layer and solid oxygen source powder laid and attached between the nonwoven fabric layer and the carbon fiber felt fabric layer, wherein the nonwoven fabric layer and the carbon fiber felt fabric layer are arranged in a stacked manner; or the suppository comprises a suppository core containing the solid oxygen source powder, an outer coating layer coating the suppository core and a leading-out thread fixedly connected with the tail of the outer coating layer. The solid oxygen source powder produces hydrogen peroxide and oxygen slowly in a humid and acid environment, the hydrogen peroxide and the oxygen are slowly released after being adsorbed by a carbon fiber felt fabric material and enhance the antibacterial and bacteriostatic effects together with a physical antibacterial agent, and meanwhile, the produced oxygen has the specific inhibition effect on anaerobic bacteria, promotes growth of aerobic bacteria, increases the cell activity, accelerates healing of a wound surface of a mucous membrane and shortens the repair period, so that bacterial colonies in a vagina are restored to the normal value; besides, the treatment purpose is achieved through physical characteristics of materials mainly, and compared with conventional drug treatment, the suppository has incomparable advantages.

The invention provides a method for repairing a drive disk of a coal mill and a repair system for the drive disk of a coal mill, and relates to the technical field of repairing a coal mill.
