Excerpt: ... bat can be laid over it and clay tamped against it in such a way that it will be secure. All cracks that are larger than J inch should be covered with bats. Following this method the drain is finished and secured as the work proceeds from the outlet up grade. When the point for joining a branch is reached, the proper tile with Y branch should be placed in position anc3 the opening covered securely to await the construction of the branch line. When large tiles are used--9-inch and larger--it will be necessary for the workman to walk in the bottom as he grades, which work must be done with the shovel. The same care should be used in securing the proper grade as above noted. Tile should be laid from the outlet up, the workman standing in the bottom and placing them with his hands. They should be secured in place by clay filling, which should be tamped firmly between the sides of the ditch and the tile. If the clay is so hard that it must be loosened by the pick, the tediousness and expense of the work will be greatly increased. It will be observed that the tools necessary for this work are few: the line or target for obtaining the grade as given by the survey, a working line 100 feet long, ditching spade, round-pointed shovel, tile-hook, and cleaning scoop of the size required for the tile to be laid. The practice of many ditchers is to lay the tile by hand, walking backward in the ditch in front of the tile as they are laid. But it is wholly practicable, when the ditch is properly prepared at the bottom, to lay the tile with a hook from the surface in a perfectly, satisfactory way where the ditches are only 3 or 4 feet deep. Difficulties in Constructing Tile Drains. The engineer is often consulted regarding difficulties which are...
