Lap joint curtain hole site laying device and method
The invention provides a lap joint heavy curtain hole site laying device and method. 4-6 iron rings for identifying curtain grouting hole positions are fixed to the left side frame of a rectangular frame, rivets corresponding to the iron rings in a one-to-one mode are arranged on a right side frame, the connecting lines between each pairs of rivets and the corresponding iron rings are consistent to design angles of corresponding curtain grouting holes, one end of each rubber band is fixed to the corresponding rivet, and the other end of each rubber band is arranged on the corresponding rivet in a sleeving mode. A line hammer is arranged on a right side lengthened section of the top frame of the rectangular frame, and a bottom downward lengthened section of the right side frame is grounded and supported. At a concrete lining section, the positions of the side wall corresponding to the iron rings are the curtain grouting hole positions. At a non-lining section, the rubber bands penetrate through the iron ring to be stretched in the lengthened line directions of the connecting lines of the rivets and the iron rings, and intersection points of the rubber band and actual side lines of actually excavated side walls are hole distribution positions. The lap joint heavy curtain hole site laying device is simple in structure and simple and convenient to operate. The lap joint heavy curtain hole site laying method is high in hole distribution speed and hole distribution accuracy, and a large amount of repeated measurement and lofting work is avoided.
