Problems solved by technology

[0002] At present, the multi-head slotting machine used in the construction of the underground diaphragm wall is only a combination of multiple submersible drilling rigs side by side. Since the holes formed by each single submersible drilling rig are independent circles, there is a serious necking between the holes. , the shape of the groove segment is very irregular

Abstract

The invention relates to a multi-bit drill corrector for grooving for an underground concrete continuous wall. The multi-bit drill corrector comprises five motors, wherein the five motors are arranged side by side at the upper end of a multi-bit drill; a drill rod A is arranged at the lower end of the middle motor; a drill bit is arranged at the lower end of the drill rod A; crank shafts are arranged at the lower end of the four motors on two sides respectively; the lower ends of the crank shafts are connected with drill bits through drill rods B; sliding sleeves B are arranged on both the drill rod A and the drill rods B; and each sliding sleeve B is connected through a connecting rod A. The multi-bit drill corrector is characterized in that sliding sleeves A are arranged on the four crank shafts; the two sliding sleeves A on the left side are connected with two cutter arbors on the left side through left connecting rods B; and the two sliding sleeves A on the right side are connected two cutter arbors on the right side through right connecting rods B; and cutter bits are arranged on each cutter arbor.

Description

1. Technical field [0001] The invention relates to a multi-head drill corrector, in particular to a multi-head drill corrector for forming grooves in underground concrete continuous walls. 2. Background technology: [0002] At present, the multi-head slotting machine used in the construction of the underground diaphragm wall is only a combination of multiple submersible drilling rigs side by side. Since the holes formed by each single submersible drilling rig are independent circles, there is a serious necking between the holes. , the shape of the groove segment is very irregular. 3. Contents of the invention: [0003] The invention makes up for the shortcomings of the multi-head slotting machine, and provides a multi-head drill corrector with regular and smooth slotting. [0004] The present invention is achieved through the following technical solutions: [0005] A multi-head drill correction device, including five motors arranged side by side at the upper end of the m...
