Shallow undercut tunnel of burying of ultrahigh -voltage power cable is arranged many times to unilateral

The utility model relates to an use the power cable tunnel on the power transmission and transformation circuit, shallow undercut tunnel of burying of ultrahigh -voltage power cable is arranged many times to unilateral especially, its structural feature lies in, including the tunnel body, extra -high -tension cable frame and access path, the cross -section of the tunnel body is shape of a hoof structure have barrel vault and both sides arc side wall, two arc side walls all are the arc transitional coupling with the barrel vault, and extra -high -tension cable puts up from top to bottom the distribution numbers layer and installs on one of them arc side wall of the tunnel body, occupies the half the space in tunnel, and the access path is then arrange in second half space in tunnel. The advantage lies in to the arc side wall replaces original stalk, and the arch of having utilized the arced sidewall soil body has effectively been solved the problem that the lateral wall caved in before the side wall was strutt
