Steam turbine concrete cushion block production process
The invention discloses a steam turbine concrete cushion block production process. The steam turbine concrete cushion block production process comprises step 1, concrete foundation pretreatment which comprises removing an unstable layer which is arranged on the surface of a concrete foundation and performing cleaning; step 2, grouting template installation which comprises arranging a mortar cushion block grouting template on the concrete foundation, falling a bedplate onto the template and controlling the position of a mortar outlet of the template to be 7 to 8 mm lower than the bottom surface of the bedplate; step 3, mortar cushion block pouring which comprises injecting grouting materials into the grouting template twice, controlling 25 to 35 mm of weld reinforcement to be reserved between the grouting surface and the lower surface of the bedplate during the first grouting and performing the second grouting after 15 to 30 minutes until mortar overflows; step 4, maintenance which comprises performing the maintenance for 36 to 72 hours under 10 to 35 DEG C. According to the steam turbine concrete cushion block production process, the grouting template is arranged reasonably, a 7 to 8 mm of groove is formed at the position of the mortar outlet, the twice grouting is performed, the height of the second grouting is controlled, and accordingly a steam turbine concrete cushion block which is clean and smooth in surface and excellent in comprehensive mechanical property can be obtained.
