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 first special locking section steel top segment 1, and the perpendicularity of the first section steel is adjusted and fixed through the first special locking section steel top segment 1.
The top section 1 special for the first locked-notch profile steel is also provided with a temporary laying rod seat 2 and a special catch wheel 4 with adjustable height for facilitating the insertion of the second profile steel.
The length of the inclined stay bar 3 is adjusted by a screw pair provided with left and right backward and forward screw threads, a pair of rotating shaft seats are arranged at the bottom of the inclined stay bar, one end of the inclined stay bar is welded with the stay bar, the other end of the inclined stay bar is fixed on a guide wall by a planting screw and is connected with a pin shaft, the top of the inclined stay bar is connected with the top end of a special top section 1 of the first lock-notch section steel by a bolt through a cross beam, and the section steel is matched with a rotating shaft 5 and a rotating shaft fixing base 6 for; and the requirements of the insertion construction process of the section steel and the fine adjustment of the first section steel during the moving process.
