Abstract

Abstract

In order to solve the problems of small construction space， complex detector composition and large number of components faced by the neutrino detector part of the Jinping underground laboratory， the construction steps were determined based on the on-site engineering survey and the space and construction conditions of the Jinping underground laboratory. The beams and columns of the stainless steel tank were prefabricated in factories and installed on site by lifting and welding. The spherical reticulated shell adopted a scheme of installing the inner half as a whole and lifting the outer half in multiple pieces. The Plexiglass glass ball was divided into five layers of monomers， and each layer of monomers was pre-aggregated from multiple small pieces in the hall. Adjacent two layers of monomers were aggregated from bottom to top on-site in the stainless steel tank. The construction process was simulated by using the ABAQUS to analyze the feasibility of the construction scheme.
