This invention relates to the field of incinerator construction and masonry technology, specifically a method for constructing the lining of a municipal solid waste incinerator. The method includes: planning the masonry path based on a three-dimensional digital model of the incinerator body to generate a digital scheme for lining construction. An improved wavefront propagation algorithm is employed, using geometric constraints of already constructed blocks and a minimum mortar joint threshold to control wavefront expansion, dynamically generating a masonry sequence that conforms to the curved surface of the incinerator body. Prefabricated refractory blocks with positioning markers are used, and laser tracking positioning is used to complete the registration of the digital scheme with the on-site space. During construction, three-dimensional point cloud data is collected in real time to construct a masonry deviation field.

This method can improve the conformity of the lining surface and the uniformity of mortar joints, suppress deviation accumulation, and improve the construction accuracy and stability of multi-layer refractory block masonry.
