Method for constructing structure

Abstract

The present invention relates to a method for constructing a structure, the method comprising constructing an underground structure on the ground, and then constructing the structure in the ground by sinking same into the ground.

1 . A structure construction method for constructing an underground structure on a ground and sinking the same into the ground, the method comprising steps of:
 A) constructing a foundation plate ( 10 ) and a pile ( 20 );   B) installing a jack-down device and constructing a basement structure;   C) performing excavation under the foundation plate ( 10 ) and sinking the underground structure; and   D) dismantling the jack-down device and fixing the pile ( 20 ),   wherein the jack-down device is installed on the foundation plate ( 10 ), such that a degree of sinking of the underground structure is controlled by adjusting force of the jack-down device,   wherein the excavation under the foundation plate ( 10 ) and the sinking of the underground structure are performed in parallel.   
     
     
         2 . A structure construction method for constructing an underground structure on a ground and sinking the same into the ground, the method comprising steps of:
 a) constructing an outer foundation plate ( 50 ) and a pile ( 20 );   b) installing a jack-down device;   c) performing excavation under the outer foundation plate ( 50 ) and sinking the underground structure; and   d) dismantling the jack-down device and fixing the pile ( 20 ),   wherein the jack-down device is installed on the outer foundation plate ( 50 ), such that a degree of sinking of the underground structure is controlled by adjusting force of the jack-down device,   wherein the excavation under the outer foundation plate ( 50 ) and the sinking of the underground structure are performed in parallel.   
     
     
         3 . The method of  claim 1  or  2 , wherein the sinking is performed by a weight of the underground structure. 
     
     
         4 . The method of  claim 1  or  2 , wherein the sinking is performed by a weight of the underground structure and additional external force. 
     
     
         5 . The method for  claim 4 , wherein the additional external force is generated by:
 increasing the load by adding a temporary load to the underground structure;   using a rock anchor or earth anchor installed in the ground; or   using main surface friction of the pile installed in the ground.   
     
     
         6 . The method of  claim 1  or  2 , wherein the excavation is performed by:
 using excavation equipment; 
 using a water jet; or 
 suctioning and discharging soil from the ground. 
 
     
     
         7 . The method of  claim 1 , further comprising:
 constructing an additional foundation plate on the foundation plate ( 10 ) and the pile ( 20 ) after the step D).   
     
     
         8 . The method of  claim 2 , further comprising:
 constructing an additional foundation plate on the outer foundation plate ( 50 ) and the pile ( 20 ) after the step d).
