In order to improve the impermeable crack technology of concrete culverts, through the analysis of the principle of anti-leakage in construction engineering, aiming at seepage prevention of concrete culverts, the anti-leakage technologies of the system such as adding cushion beams and seepage interception rings are studied and proposed, and such three practical load reduction and anti-cracking methods for culverts as geogrid reinforced soil method, concrete cover plate protection method, and culvert bottom inverted arch method are discussed and proposed. For the concrete reinforcement of culverts, two application schemes of epoxy resin coated steel bars and GFRP bars are proposed, which effectively improve the anti-leakage and anti-cracking performance of the culvert, prolong the service life of the culvert, and reduced the maintenance cost in the use stage. The results can provide some enlightenment and reference for anti-leakage and anti-cracking of building structures in the future.
