According to the design plan, a cast-in-place rainwater inlet construction method is adopted, and according to the construction sequence, a frame of a cast-in-place rainwater inlet production mechanism (4) is constructed above the square rainwater inlet construction groove (3); Step 2: Tamp the construction edge of the square rainwater inlet construction groove (3), move the edge of the square rainwater inlet construction groove (3) outward by 1 mm, dig a placement groove there, place the adjustable slide rail (6), and fix it, then install the first mounting frame (10) and the second mounting frame (15) at the upper and lower ends of the support assembly (9), respectively, and insert the first connecting rod (7) into the second mounting frame (15) installed by the support rod (901) of the support assembly (9), connect the sliding rod (5) with the first connecting rod (7), and evenly insert the second connecting rod (11) into the first mounting frame (10) of the sliding rod (5) and the support rod (901), thereby completing the assembly of one side of the cast-in-place rainwater inlet production mechanism (4); Step 3: Then use a crane to lift the assembled frame, and connect the second locking frame (19) installed on the second mounting frame (15) below the support rod (901) with the track (18) of the adjustable slide rail (6), complete the installation of the frame on one side of the cast-in-place rainwater inlet production mechanism (4), and assemble the frame on the other side. After completing the assembly of both sides, use the rod body to fix the frames on both sides, and install the positioning top block (24) of the pushing component (8) on the sliding rod (5), and then install the positioning block (23) on the support rod (901), and then install the support frame (22) on the top of the first connecting rod (7), and push the screw rod (20) through the support frame (22), the positioning block (23) and the positioning top block (24) in sequence to connect; Step 4: According to the designed size of the square rainwater inlet construction groove (3), the sliding rod (5) is pushed by the pushing component (8) to move, and the sliding rod (5) is pushed to the construction standard position, and the bottom template is laid on the top of the square rainwater inlet construction groove (3), and then the square rainwater inlet mold (26) is hoisted above the bottom template by a crane, and the square rainwater inlet mold (26) is constructed; Step 5: Then move the first locking frame (14) fixed on the hinge (13) on the connecting fixing plate (902), loosen the plug-in column (1403) of the first locking frame (14), separate the locked hinge (13), and make the plate body of the connecting fixing plate (902) movable, and place the second fixing plate (2601) of the square rainwater outlet mold (26) inside the connecting fixing plate (902), and re-merge the plate body of the connecting fixing plate (902), loosen the stud (1202), and insert the locking column (1203) into the connecting fixing plate (902) and connect the second fixing plate (2601), and re-tighten the stud (1202) to complete the fixing of the connecting fixing plate (902) and the second fixing plate (2601), and complete the connection of the square rainwater outlet mold (26); Step 6: Cast in the square rainwater inlet mold (26). After the casting is completed and solidified, separate the steel frame of the square rainwater inlet mold (26). By moving the first connecting rod (7) on the adjustable slide rail (6), the mold installed by the first connecting rod (7) is pulled and separated from the mold. Then use a crane to lift the casting and move it away from the bottom template. Place the casting into the square rainwater inlet construction groove (3) to complete the construction.
