### English: The module is a hollow structure. After the combined masonry, the longitudinal holes are connected, and the transverse holes are intersected. After the hole core is poured, the cast-in-place concrete network structure is formed, which <v>plays a secondary reinforcement and waterproof role</v>.
### Errors: There is a minor style/awkward error at "plays a secondary reinforcement and waterproof role" within <v></v>.

### Improved English: The modules are of hollow structure, with connected holes vertically and interpenetrated horizontally; the cast-in-place concrete mesh structure is formed after pouring of the cores of holes, playing the role of secondary reinforcement and waterproof.
