Claims

[Scope of Claim for Utility Model Registration] (1) A box measure to be inserted into a manhole at a connection point of a buried pipe; an elongated abutment plate for positioning, and the abutment plate is rotated between a use position in which the abutment plate extends at a right angle to the box measure at a lower end of the box measure and a folded position in which it substantially overlaps the box measure; An apparatus for measuring the construction height of a buried pipe, characterized by comprising a connecting member which is freely movable and which is connected and supported so that the upper surface of the abutment plate intersects the zero scale of a box scale in the use position. (2) The apparatus for measuring the construction height of a buried pipe as set forth in claim (1) of the utility model registration, characterized in that the connecting member is rotatably supported around the axis of the box measure. (3) The utility model registration claim described in paragraph (1) is characterized in that the box measure is equipped with a horizontal collimator on the upper side to maintain the box measure along a vertical line. A device for measuring the construction height of buried pipes. (4) A link rod is connected between a sliding ring that slides along the box scale and a portion of the abutment plate that is closer to the center than the tip, and the sliding ring is stretched from the top end of the box scale. The construction height measuring device for a buried pipe as set forth in claim (1) of the registered utility model, characterized in that the abutment plate is rotated by a sliding operation using a wire.
