8. The basement post-cast strip waterproof structure of claim 7, wherein: the lower shaping net piece (1) is fixedly provided with a positioning plate (27) at the bottom center, the positioning plate (27) is positioned between two arched supporting plates (24), and the upper shaping net piece (28) is fixedly arranged at the top center of the water stop plate (2).
9. A construction method of a basement post-cast strip waterproof structure is characterized by comprising the following steps:
s1: excavating on the surface of the foundation part (18) to form a groove (19), adding concrete on the top of the foundation part (18) and the inner side of the groove (19), shaping the concrete to form a concrete cushion part (20), and then sequentially paving a waterproof coiled material (21), a waterproof coating (22) and a non-woven fabric (23) on the top of the concrete cushion part (20) from bottom to top;
s2: firstly, placing an arched support plate (24) positioned on the left side to the left of the center of the top of a non-woven fabric (23), then placing a support pad (25) to the center of the top of the non-woven fabric (23), enabling the left side wall of the support pad (25) to be attached to the arched support plate (24), then placing a water stop (26) to the top of the support pad (25), enabling one end of the water stop (26) to enter the inside of a groove on the side surface of the arched support plate (24), then attaching the other arched support plate (24) to the left from the right side, enabling the right side wall of the support pad (25) to be attached to the arched support plate (24), and at the moment, the two arched support plates (24);
s3: placing the lower shaping net sheet (1) on the tops of the two arched support plates (24) so that the positioning plate (27) is positioned between the two arched support plates (24);
s4: the two water stop plates (2) are respectively placed at the tops of two ends of the lower shaping mesh (1), when the water stop plates (2) are placed, two positioning side plates (7) at the bottoms of the water stop plates (2) are respectively located at two sides of the end part of the lower shaping mesh (1), in the placing process of the water stop plates (2), the positioning side plates (7) synchronously descend along with the water stop plates (2), when the positioning side plates (7) descend, two sides of the end part of the lower shaping mesh (1) extrude guide blocks (12) at the end part of the positioning sliding blocks (9), the guide blocks (12) extrude second springs (10) through the positioning sliding blocks (9) after being extruded, at the moment, the second springs (10) are compressed and shortened, the guide blocks (12) drive the positioning sliding blocks (9) to retract towards the inside of a second mounting groove (8), and the positioning side plates (7) can normally descend;
s5: after the bottom of the water stop plate (2) is attached to the end of the lower shaping mesh (1), the positioning side plate (7) moves to a set position in the longitudinal direction at the moment, then the water stop plate (2) is pushed in the transverse direction, and then the water stop plate (2) drives the positioning side plate (7) to move in the transverse direction, in the transverse movement process of the positioning side plate (7), when the guide block (12) moves to the position of the positioning through hole (3), due to the pushing of the second spring (10), the positioning slide block (9) pushes the guide block (12) to enter the inner side of the positioning through hole (3), and an operator can have large resistance when pushing the water stop plate (2);
s6: at the moment, an operator can push the pressing plate (17), so that the pressing plate (17) pushes the positioning slide block (9) to enter the positioning through hole (3) through the second limiting column (16), in the moving process of the positioning slide block (9), the positioning slide block (9) extrudes the lifting fixture block (5) through the guide block (12), so that the lifting fixture block (5) slides inwards along the inner wall of the first mounting groove (4), and along with the movement of the positioning slide block (9), when the limiting clamping groove (11) moves to a position collinear with the lifting fixture block (5), the lifting fixture block (5) enters the limiting clamping groove (11) under the pushing of the first spring (6), and then locking is completed;
s7: then, mounting the upper shaping net (28) on the top of the water stop plate (2) to form a post-pouring belt;
s8: and finally, filling concrete to one side of the two arched support plates (24) far away from each other to form the basement bottom plate, and finishing the operation.
