Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for measuring and displaying the depth of the buried state of various pipes and wirings buried in the ground and the distance from other buried objects.

[0002]

2. Description of the Related Art As shown in FIG. 4, when a pipe or wiring is buried in the ground, a trench 1 having a predetermined depth is excavated in the ground, and then a buried object 2 is defined in the trench 1. They are installed so that the depth position and the arrangement interval are set, and the recessed groove 1 is backfilled to be buried.

By the way, in the above-mentioned burial work, it is obliged to report to the government office having jurisdiction that the burial object 2 is in a predetermined burial condition. It is necessary to measure the burial depth of the burial object 2 and the vertical spacing between the burial object and other burial objects, and take a photograph of this together with the construction name.

Conventionally, as shown in FIG. 4, the method of measuring and displaying the burial depth and interval of the buried object is to install the horizontal rail 3 on the excavated groove 1 and pull out the separately prepared tape measure 4. With the reference tip of the tape being in contact with a position to be measured, such as the upper surface of the buried object 2, the winding portion of the tape measure 4 is placed on the horizontal rail 3, and the scale of the tape measure 4 is attached to the horizontal rail. The depth is measured by reading at the position of the lower surface of No. 3, and when taking a picture of this state, the construction display plate 5 which describes the contents of construction is held at the rear position of the horizontal rail 3.

[0005]

By the way, in the conventional measuring method as described above, since the tape measure 4 is only placed on the horizontal rail 3, the installation of the tape measure 4 is unstable and the installation work is troublesome. In addition to the above, accurate measurement cannot be performed, and in order to measure the vertical arrangement distance between the buried object 2 and the existing other buried object 2a, the same procedure as above is applied to each of the buried object 2 and the other buried object 2a. Since the tape measure 4 must be brought into contact with the above, the labor is doubled and the measurement accuracy becomes poor.

There is also a problem that the construction display board 5 must be held by another worker during photography, and two workers are required.

Therefore, an object of the present invention is to bury an underground buried object in which the depth of the buried object and the distance from another buried object can be measured easily and accurately, and a photograph can be taken by one person. An object is to provide a measuring device.

[0008]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention is capable of winding and withdrawing on a horizontally long rod which is installed over a concave groove excavated in the ground for burying an object to be buried. The required number of tape measures are attached so that the position of the tape can be adjusted in the lengthwise direction of the horizontal rod, and the construction display plate is attached to the horizontal rod.

[0009]

[Operation] After placing the object to be buried in the groove that has been excavated on the ground, place the horizontal rod on the groove in a erected manner, pull out the tape measure attached to the horizontal rod and hang it downward, and then insert the tip of the tape. If it is brought into contact with the object, the depth of the buried object from the ground can be measured by the scale of the tape measure.

Further, in measuring the vertical distance between the buried object and the existing buried object where the buried object intersects, a plurality of tape measures are placed so that the lower ends of the tape measure come into contact with the corresponding buried object and other buried objects. It suffices to select the mounting position for the horizontal rod and bring the tape measure into contact with the buried object and other buried objects, and the vertical distance can be measured on the ground by the difference between the scales of the two tape measures.

Further, at the time of taking a picture, if the construction display plate is fixed on the horizontally long rod with a mounting portion, the construction display plate can be taken without separately holding it.
