Vertical plates flush with the ground are welded to the four sides of the bottom steel plate. Filling concrete is backfilled on both the inner and outer sides of the vertical plates. A top steel plate flush with the ground is fixed to the top of the vertical plates. Extensions are integrally formed on the four sides of the top steel plate outside the vertical plates. Multiple sets of steel bars arranged in a triangular pattern are welded to the bottom surface of the extensions. The steel bars are cast inside the filling concrete. Corner slots are provided at the corners of the extensions, and multiple intermediate slots are provided between the corner slots. Bottom columns are fitted into the inner sides of the corner and intermediate slots. After being leveled with the extensions, the bottom columns are fixed to the corner or intermediate slots by full welding around their perimeter. An extension frame, comprising a central column and corner columns, wherein the tops of the central column and corner columns are of equal height and are each composed of multiple rectangular tubes inserted and fitted together in sequence; The top frame includes top columns and top beams; the top columns include a middle top column and corner top columns; the upper part of the middle top column near the inner side of the darkroom or shielded room and the upper part of the corner top columns near the inner side of the darkroom or shielded room are welded with supporting steel plates; the top beams are fixed to the top surface of the supporting steel plates. The bottom column, rectangular tube, and top column are all integrally formed with a flared square constriction. The bottom of the bottom column, the bottom of the rectangular tube, the bottom of the top column, and the square constriction are provided with through holes arranged in an equilateral triangle. The bottom rectangular tube fits into the square constriction of the bottom column, the bottom of the middle top column fits into the square constriction of the middle column, and the bottom of the corner top column fits into the square constriction of the corner column. After fitting, bolts are inserted into the through holes to lock them in place, and after leveling and welding, they are fully welded in place. The shielding module includes side wall modules and a top cover module. The side wall modules are spliced ​​and enclosed outside the extended frame; the top cover module is spliced ​​and enclosed outside the top frame. The bottom side wall modules are bolted to the top steel plate and then fully welded after leveling and alignment. The two sides of the side wall modules are bolted to the middle or corner columns and then fully welded after leveling and alignment. The adjacent side wall modules are bolted and then fully welded. The two sides of the top cover module are bolted to the top crossbeam on the opposite side and then fully welded after leveling and alignment. The other two sides of the adjacent top cover modules are bolted and then fully welded.

2. The modular enclosure for anechoic or faraday chambers according to claim 1, characterized in that: A shielding layer, made of 3mm thick cold-rolled steel plate, is laid at the bottom inner side of the sinkhole. An embedded plate is installed on the top surface of the shielding layer. A galvanized mesh skeleton is laid on the embedded plate, and angle steel is fixed between the galvanized mesh skeleton and the embedded plate at intervals. A bottom layer of concrete is poured inside the galvanized mesh skeleton. A smooth layer is ground on the top surface of the bottom concrete, and a reflective floor is bonded to the top surface of the smooth layer. The reflective floor is made of 5mm thick galvanized steel plate and is fixed to the galvanized mesh skeleton with self-tapping screws. The bottom steel plate is fully welded to the reflective floor.

3. The modular enclosure for anechoic or faraday chambers of claim 1, wherein: Both the sidewall module and the top cover module include a shielding steel plate. A frame is welded onto the shielding steel plate, and multiple through holes are spaced apart around the frame. A grid body is welded to the inside of the frame on the shielding steel plate. Extended plates protruding from the outside of the frame are integrally formed on both sides of the shielding steel plate. The remaining two sides of the shielding steel plate are flush with the outside of the frame. The inner surface of the extended plate of the sidewall module is fitted with the middle column or corner column, and the frame is fully welded to the middle column or corner column after being bolted. The extended plate of the top cover module is fitted with the bottom surface of the top beam, and the frame is fully welded to the top beam after being bolted.

4. The modular enclosure for anechoic or faraday chambers of claim 1, wherein: Multiple suspension rods are fixed to the top of the top beam, and the suspension rods are suspended from the embedded steel plates in the civil engineering ceiling.
