Preliminary construction method of in-plant trench of nuclear power plant

Abstract

The embodiment of the present invention is a preliminary construction method of an in-plant trench of a nuclear power plant, the method. The method includes: constructing a plurality of buildings for generating an atomic energy; constructing a trench between the buildings via a platform configured to adjust a level of the trench with an installation level of the trench; and backfilling an area between a ground and the trench, after the construction of the trench.

1 . A preliminary construction method of an in-plant trench of a nuclear power plant, the method comprising:
 constructing a plurality of buildings for generating an atomic energy;   constructing a trench between the buildings via a platform configured to adjust a level of the trench with an installation level of the trench; and   backfilling an area between a ground and the trench, after the construction of the trench.   
     
     
         2 . The preliminary construction method of an in-plant trench of a nuclear power plant according to  claim 1 , wherein
 the platform is previously imposed on the trench, and thereafter the construction of the trench is executed.   
     
     
         3 . The preliminary construction method of an in-plant trench of a nuclear power plant according to  claim 1 , wherein
 the platform is installed with respect to the ground, and thereafter the construction of the trench is executed.   
     
     
         4 . The preliminary construction method of an in-plant trench of a nuclear power plant according to  claim 1 , wherein
 the trench is structured as a trench module with which at least a pipe or a cable is previously integrated.
