Description

  The present invention relates to a filling material input management device for an underwater structure constructed by introducing a filling material.

  In revetment work and underwater structure construction work, construction methods for constructing underwater structures by inserting filling materials such as earth and sand, rock sludge and crushed stone into structures composed of caissons and steel cells are known. (For example, Patent Document 1).

  The underwater structure such as the caisson is divided into a plurality of charging points by the partition wall, and the charging point is opened at the top, and after the water is placed and set, the filling material is uniformly charged therein. In addition, it is preferable to minimize the thickness of the partition wall in order to reduce costs, and it is necessary to keep the difference in the filling height of the adjacent input space during construction at a certain range, which exceeds the certain range. There is a risk of the partition wall being damaged by the uneven earth pressure.

  Therefore, in the conventional management method, red having a weight at the lower end of the scaled striated body is used, or an ultrasonic measuring instrument is used. However, in the method using red, since the worker performs measurement work by putting red into the charging point filled with seawater etc. on the underwater structure, the measurement is performed with the charging of the filling material suspended for safety management. And a time loss occurs because the input operation is interrupted. In addition, it is necessary to measure all of the plurality of input points, and it takes time to move the worker. Furthermore, it takes time and effort to record measurement values, and there is a risk of inducing errors such as measurement errors and entry errors.

  In addition, in the method using an ultrasonic measuring instrument, it is necessary to wait until the seawater in the input location becomes cloudy and the bubbles disappear, which requires time for the measurement operation and hinders the input operation.

  On the other hand, in order to improve the efficiency of the measurement work, the covered wire is laid on the inner wall of the underwater structure so that the tip of the wire is at a predetermined position in the vertical position of the inner wall, and the conductor is insulated from the conductor at the tip. A terminal treatment unit that is exposed and treated so as to be exposed, measures the electrical resistance between the coated electric wire and the ground, and performs terminal treatment at the tip of the coated electric wire by depositing filling material in the underwater structure. There has been proposed a method of measuring the top height and the amount of filling in the filling material by detecting that the electrical resistance is lowered by exposing the conductor to the water due to damage to the part (for example, Patent Document 2). ).

  In the method of Patent Document 2, accurate measurement cannot be performed when the unprocessed portion of the terminal is not damaged by the filling material or when the wire is cut off due to the impact of filling the filling material. . In addition, the cost of the covered wire itself and the cost of installing the covered wire are increased, and the covered wire remains as a foreign object in the underwater structure.
