hoisting a drainage box culvert, wherein the drainage box culvert is hoisted into the foundation pit through a crane;

sealing treatment, namely sealing the joints of the adjacent drainage box culverts;

backfilling, namely backfilling two sides of the drainage box culvert.

The implementation principle of the rapid construction method of the drainage box culvert provided by the embodiment of the application is as follows: the staff carries out each step orderly, realizes the modularization installation of the drainage box culvert, ensures that the staff runs purposefully, improves the installation efficiency of the drainage box culvert, and reduces the use cost of the drainage box culvert.

The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
