This invention relates to a prefabricated 3D-printed box-type concrete retaining wall and retaining wall system. The prefabricated 3D-printed box-type concrete retaining wall is assembled from 3D-printed concrete retaining wall units. Each 3D-printed concrete retaining wall unit is an integrated 3D-printed concrete structure, consisting of an arched outer wall panel, a concave inner wall panel, and concave side wall panels, which enclose a cavity. A transverse keyway is formed between the concave side wall panels of adjacent 3D-printed concrete box-type retaining wall units. Shear keys are formed by casting cement-based material within the transverse keyway, enabling the combined load-bearing capacity of the 3D-printed concrete retaining wall units. Under the same loading conditions, the peak bearing capacity of the structure of this invention is significantly improved compared to traditional vertical box-type retaining walls, and the bearing performance is further enhanced under simulated backfill conditions, demonstrating good engineering applicability and green construction value.

The present invention relates to a heat-absorbing module (1) of a device for wrapping and passive fire protection of elements to be protected. The module is characterized in that it extends along a longitudinal axis (X-X'), wherein it comprises two rectangular strips of fire-resistant barrier fabric (11, 12), wherein the two fabric strips (11, 12) are assembled so that their respective long sides are parallel to the longitudinal axis (X-X') of the module (1) and are stitched together to form a plurality of closed oblong storage pockets (13) having a longitudinal axis (Y-Y'), said storage pockets (13) being parallel to each other along their longitudinal sides, and the longitudinal axes (Y-Y') of the storage pockets (13) being perpendicular to the longitudinal axis (X-X') of the heat-absorbing module (1), and wherein at least one of the storage pockets (13) is filled with a heat-absorbing material (100) in powder form.

This utility model proposes a prestressed composite beam structure with semi-circular corrugated tube confined concrete compression members, belonging to the field of building beam structure technology. It includes a concrete top slab, with a concrete bottom slab at its base. Shear keys are respectively installed within the top and bottom slabs, and semi-circular corrugated tube confined concrete compression members connect the two opposing shear keys. Prestressed tendons, with both ends passing through the semi-circular corrugated tube confined concrete compression members, are anchored to the shear keys, connecting the semi-circular corrugated tube confined concrete compression members between the top and bottom slabs. Compared with traditional beam structures, this composite beam has a significantly improved load-bearing capacity, capable of withstanding greater loads without failure, while also exhibiting significantly enhanced stiffness and smaller deformation under load, effectively improving the safety and stability of the structure.

The lower ends of the columns are detachably connected to adjacent first and second lower crossbeams via connectors, and the upper ends of the columns are detachably connected to adjacent first and second upper crossbeams via connectors. The columns, first lower crossbeams, second lower crossbeams, first upper crossbeams, and second upper crossbeams form the main frame of the building module. Lifting rings for hoisting the main frame are detachably connected to the upper ends of the columns. This utility model not only improves hoisting safety and stability but also increases assembly and transportation efficiency.
