[0015] 1. A wire-laying device for construction engineering is provided with a guiding mechanism and a draining mechanism. When in use, ink is added into the coating chamber through the feed port and the sealing plug is blocked inside the feed port. At this time, one end of the cotton thread located inside the coating chamber is in full contact with the ink under the restriction of the coating wheel. When the guide head is pulled to drive the cotton thread to stretch to the left, the cotton thread inside the equipment wire box is drawn out and contacts with the ink inside the coating chamber under the guidance of the two second guide wheels, the two first guide wheels and the coating wheel, and then is moved to the outside for use. When the cotton thread is retracted into the equipment wire box after use, the squeezing slider squeezes the cotton thread through the two squeezing wheels under the elastic force of the squeezing spring, so that the ink attached to the cotton thread is squeezed and falls into the coating chamber for collection, so as to avoid the ink entering the equipment wire box with the cotton thread to cause pollution and waste, thereby improving the practicability of the device.

[0016] 2. This kind of wire-laying device for construction projects is equipped with a coating chamber. Since the inner bottom of the coating chamber is funnel-shaped, the ink inside the coating chamber will gather in the middle of the inner bottom of the coating chamber, and then contact with one end of the cotton thread located on the coating wheel, thereby improving the efficiency of the device in using ink and further improving the practicability of the device.

A cotton thread 21 is arranged inside the equipment wire box 10, and one end of the cotton thread 21 is sequentially passed through the first guide wheel 18 and the second guide wheel 20 is rotatably connected to the second guide wheel 20. After passing through the guide cavity 14 on the right, the wire through hole 17 on the right, the coating cavity 13, the wire through hole 17 on the left and the guide cavity 14 on the left, it is fixedly connected to the right end of the guide head 12. The outer wall surface of the cotton thread 21 is in rolling contact with the top ends of the two first guide wheels 18, the bottom end of the coating wheel 19 and the bottom ends of the two second guide wheels 20 respectively. A draining mechanism is provided on the upper right side of the inner cavity of the coating cavity 13. The draining mechanism includes two extrusion wheels 22 that are in extrusion contact with the cotton thread 21. An extrusion sleeve 23 in an inclined state is fixedly installed at the upper right side of the coating cavity 13.
