Detailed Description
The present invention will be described in further detail with reference to the following examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1 to 5, the adjusting and fixing device for the first fore-lock section steel of the underground continuous steel wall of the invention comprises a special top section 1 for the first fore-lock section steel, a height-adjustable holding rod seat 2, an inclined stay bar 3, a special catch wheel 4, a rotating shaft 5, a rotating shaft fixing base 6 and the like.
The special top section 1 for the first locking notch section steel is connected to the top end of the first section steel through a connecting plate and a bolt, and the whole section is arranged on the ground; in addition, the upper end of the diagonal brace 3, the rotating shaft 5, the rotating shaft fixing base 6 and other parts of the first section steel adjusting and fixing device are all installed and fixed on the top of the special top section 1 for the first section steel, the perpendicularity of the first section steel is adjusted through the special top section 1 for the first section steel, and the first section steel is fixed.
