Problems solved by technology
[0002] The quality of the concrete block determines whether the entire steam turbine unit can operate safely and stably. The traditional steam turbine mortar block production process is prone to air bubbles during the pouring process, and the performance of the produced block is poor. Correct construction process plus appropriate construction The tool can not only avoid the generation of air bubbles during the mixing process of the slurry as much as possible, but also eliminate the air bubbles formed in the slurry to the greatest extent during the pouring process. Therefore, optimizing the construction process and making construction tools are urgently needed solutions for the current concrete block technology. question

Embodiment Construction
[0017] Attached below figure 1 And the specific embodiments further illustrate the present invention.
[0018] A manufacturing process of a mortar block for a steam turbine body includes the following steps:
[0019] (1) Shoveling the surface of the concrete foundation: chip off the cement and unstable concrete from the concrete foundation, calibrate the ground level and the center height of the steam turbine, and the depth of the shovel should ensure that the concrete foundation surface is solid concrete with a plane roughness of 15mm, the surface of the concrete foundation should be cleaned after removing the chisel chips and dust by shoveling the surface of the concrete foundation
[0020] (2) Install the grouting template: clean the surface of the steam turbine table 2 thoroughly, determine the position elevation and elevation of the table 2, lift the table 2, and install the rigid plastic foam template into the shoveled surface. The steel wire measures the level and elevation ...

Abstract
The invention provides a technology for manufacturing a mortar cushion block of a steam turbine body. The technology includes the following steps that (1) hair shoveling is conducted on the surface of a concrete foundation; (2) a grouting formwork is mounted; (3) the mortar cushion block is poured, wherein pouring relates to the specific steps of a, maintaining and blending the foundation, b, mixing and pouring a grouting material and c, initially maintaining the mortar cushion block; and (4) the grouting formwork is dismounted. According to the technology, a traditional construction process is optimized, and bubbles are reduced in the stirring process of slurry; a sliding groove is additionally formed in the position of a mortar injection inlet, defoaming stopping bars are arranged on the sliding groove, the flow guiding effect is achieved, and the bubbles contained in the slurry are effectively removed in the pouring process of the slurry. The percent of pass of the mortar cushion block manufactured through the technology is high, forming is good, and labor and material consumption caused by reworking is reduced.
Description
Technical field [0001] The invention relates to the technical field of steam turbine installation, in particular to a manufacturing process of a mortar pad for a steam turbine body. Background technique [0002] The superiority of the concrete block determines whether the entire steam turbine unit can operate safely and stably. The traditional steam turbine mortar block production process is easy to produce bubbles during the pouring process, and the performance of the produced block is poor. Correct construction process plus appropriate construction The tool can not only avoid the generation of bubbles in the slurry mixing process, but also eliminate the bubbles that have been formed in the slurry to the greatest extent during the pouring process. Therefore, optimizing the construction process and making construction tools are currently urgently needed for the concrete block technology. problem. Summary of the invention [0003] The technical problem to be solved by the present ...
