s1, firstly pulling the two round handles (5118) to enable the two round handles (5118) to drive the two inserting rods (5114) to slide backwards, meanwhile, the two inserting rods (5114) drive the circular plate (5116) to slide backwards along the inner surface of the transverse groove (5115), meanwhile, the two circular plates (5116) start to extrude and compress the first spring (5117), finally, the two inserting rods (5114) completely slide into the transverse groove (5115), further inserting the protective net (4) into the groove (5111), further loosening the two round handles (5118), and under the elastic action of the first spring (5117), the first spring (5117) resets and simultaneously drives the two inserting rods (5114) to slide backwards, finally, enabling the two inserting rods (5114) to slide into the circular groove (5113), so that the protective net (4) is installed, pulling the two round handles (5118) again to take out the protective net (4) to achieve disassembly;
s2, the rotating handle (510) is rotated to enable the rotating handle (510) to drive the cross rod (58) to rotate, meanwhile, the cross rod (58) drives the second bevel gear (59) to rotate, meanwhile, the second bevel gear (59) drives the first bevel gear (57) to rotate, meanwhile, the first bevel gear (57) drives the bidirectional screw rod (51) to rotate, meanwhile, the bidirectional screw rod (51) drives the two moving blocks (52) to move oppositely, simultaneously, the two moving blocks (52) drive the two first rotating rods (54) and the second rotating rods (55) to rotate and rise, the two first rotating rods (54) and the second rotating rods (55) drive the lifting plate (53) and the protective net (4) to rise, the two baffles (56) can limit the moving blocks (52), and the protective net (4) can be lowered by rotating the rotating handle (510) reversely, so that the height of the protective net (4) can be adjusted;
s3, the left side of one base (3) is in butt joint with the right side of the other base (3), meanwhile, the insert block (61) is inserted into the square groove (62), the fixing block (65) is further pulled, the fixing block (65) drives the vertical rods (64) to slide upwards, meanwhile, the second spring (66) begins to stretch, when the insert block (61) is completely inserted into the square groove (62), the fixing block (65) is further loosened, the second spring (66) plays a role in elasticity, the second spring (66) resets and simultaneously drives the two vertical rods (64) to be inserted into the inner portion of the slot (63), and therefore the installation connection of the two bases (3) and the protective net (4) is achieved.
10. The foundation pit protection analysis method based on deep foundation pit excavation of claim 9, wherein: the protective net (4) is matched with the groove (5111) in size, and the inserting block (61) is matched with the square groove (62) in size.
