Abstract

PROBLEM TO BE SOLVED: To detect a crack at an early stage by a method wherein a cord which is cut by a crack is fixed closely to a concrete nail in slope to be executed and the existence of the disconnection of the cord is detected. SOLUTION: A turndown pin 2 such as a concrete nail or the like is driven into a part in which a cord 3 is stretched and installed on a concrete face 1. Then, the cord 3 to which a terminal 5 is attached in advance at a terminal is inserted via a longitudinal groove, it is wound on the pin 2, and it is turned down and stretched so as to be U-turned. At a time when the stretch of the cord 3 is finished, mortar 4 is sprayed by compressed air, and the cord 3 is brought into close contact with the concrete face 1. Then, a case 6 which houses the terminal of the cord 3 is installed in a position at a height of about two meters from the lower part of a slope. The lid of the case 6 is removed, a circuit tester is brought into contact with the terminal 5 at the terminal of the cord 3 at the inside, and the existence of its disconnection is detected by the reading of the circuit tester. When the disconnection exists, it is visually recognized that a crack is generated.

2. Description of the Related Art Generally, in civil engineering works such as roads, dams, parks, factories, housing facilities, etc., slope construction work is carried out regardless of the size to secure a site. Many of them cut slopes at a safe angle due to geology.
Then, the cutting slopes are covered with spraying slopes of mortar or concrete for preventing scouring due to weathering, precipitation, etc., or a frame method is applied. The constructed concrete surface or mortar surface causes cracks due to deterioration of the spray layer, local or overall changes in the ground, damage due to spring water or freezing, earthquakes, and the like.

When the crack is wide due to a drastic change in the natural environment such as an earthquake, it is often possible to detect a danger by inspection.
Safety measures such as full-scale repair work will be taken. However, if the concrete surface or the mortar surface cracks that are aged over a long period of time are thin, it does not always lead to a collapse accident. However, if the crack breaks further expand, it may lead to a collapse accident. Therefore, it is desirable to continuously monitor day and night in order to detect it at an early stage. In that case, it is very difficult to predict whether it will happen in a short period of time or after a long period of time. Since it is expensive, the reality is to monitor mainly cracks that have a high probability of causing an accident.
