Temporary drainage system shall be provided in the construction area. The temporary drainage system should be compatible with the original drainage system, and should be compatible with the permanent drainage facilities as far as possible, but it should be noted that the efficiency of the permanent drainage facilities should not be reduced due to sludge deposition during use. For the drainage system, if there is no requirement in the design, the site shall have a gradient of not less than 2 ‰ towards the drainage ditch, and the longitudinal gradient of the temporary drainage ditch shall generally not be less than 3 ‰ (not less than 1 ‰ in flat areas). The cross section of temporary drainage ditch shall be determined according to the maximum flow during the construction period according to the local meteorological data; The slope gradient shall be determined according to the soil quality and trench depth, generally 1:0.7~1:1.5. The location and outlet of temporary drainage outlet shall be reasonably selected. The outlet shall be far away from buildings or structures, and shall be set in low-lying places to ensure smooth drainage.
