Earthquake-proof foundation structure for horizontal type coke oven battery

An earthquake-proof foundation structure for a horizontal type coke oven battery, which comprises:

• a plurality of foundation piles driven substantially vertically into the ground;
• a pile plate rigidly connected substantially in a horizontal position to the tops of said plurality of foundation piles;
• a base plate for mounting thereon a horizontal type coke oven battery, said base plate being placed substantially in a horizontal position on said pile plate, said coke oven battery comprising a regenerator, a plurality of coking ovens and combustion chambers alternately arranged in the horizontal direction on said regenerator, and a sole flue installed directly below said regenerator;
• and
• two sliding layers each arranged between said pile plate and said base plate and between said base plate and said sole flue of said coke oven battery, each of said two sliding layers being formed by tightly laying a plurality of steel sheets coated with graphite grease over the entire surface thereof into at least two laminations, among the surfaces of said plurality of steel sheets, those being in contact with the upper surface of said pile plate, the lower surface of said base plate, the upper surface of said base plate and the lower surface of said sole flue of said coke oven battery not being coated with graphite grease;
• said foundation structure being characterized in that:
• one of the lower surface of said sole flue of said coke oven battery and the upper surface of said base plate is provided with a longitudinal ridge and a plurality of transverse ridges, while one of the upper surface of said base plate and the lower surface of said sole flue of said coke oven battery is provided with a longitudinal groove and a plurality of transverse grooves to engage with said longitudinal ridge and said plurality of transverse ridges at locations corresponding to said riges, thereby said coke oven battery being mounting on said base plate in a state in which said longitudinal ridge and said plurality of transverse ridges respectively engage with said longitudinal groove and said plurality of transverse grooves corresponding thereto;
• and
• said pile plate and said base plate are connected to each other on the both longitudinal sides thereof by a plurality of buffers each of which comprises a bolt fixed with a plurality of reinforcing ribs at the lower portion thereof and an elastic ring engaging with the upper portion of said bolt.
