[0002] After the initial support closed-loop is completed, the construction process during invert lining construction is as follows: installation of geotextile, waterproof board and longitudinal blind pipe on the low side wall; after the installation of anti-seepage and drainage is completed, positioning and binding of the invert lining steel bars are carried out; after the steel bar binding is completed, installation of the longitudinal steel plate water stop belt, and installation of embedded tees and drain holes are carried out; finally, positioning of the invert lining formwork. During the whole construction process, how to control the unified elevation of each construction process operation is the key point of the whole invert construction operation.

[0003] The traditional invert lining construction process is that after measuring and setting out the lines, two positioning points are painted with red self-spray paint at the circumferential construction joints on both sides of the invert, two nails are driven at the positioning points, and a red line is tied to the two nails on both sides as the elevation auxiliary line for each construction process of the low side wall. This process seriously affects the operation when laying and hanging the waterproof board and geotextile, and cannot fully ensure the elevation of each process of the invert lining.
