クが発生し、損傷が進行し、耐用年数が縮減される。Concrete structures built by excavating or cutting out old technical ground, such as tunnels and retaining walls built on railways, highways, or roads, or side walls of underground parts of buildings. In TF4 structures such as , water leaks occur from concrete joints, cracks caused by earthquakes, vibrations from moving vehicles, or concrete expansion and contraction. In order to receive this water, a water guide gutter was installed along the concrete wall to direct the water to the designated drainage ditch. Problems to be Solved by the Invention In cold regions during winter, the outside air drops below freezing, so water leaking from cracks and the like freezes, producing icicles and side water. In particular, the water guide gutters attached to these structures freeze and become clogged, preventing water from flowing, and furthermore, the formation of side ice increases.
For example, when the structure is a railway tunnel, it not only damages the walls, tracks, and electrical equipment inside the tunnel, but also has a negative impact on train operation safety. For this reason, deicing requires a great deal of labor and expense. When the water guide gutter freezes, whether it is on a motorway, general road, or earth retaining wall, ice and icicles grow on the sides, which can easily damage cars and affect pedestrians. When buildings freeze, cracks occur, causing further damage and shortening their useful life.

In winter, for example in the Tohoku region, the outside air can drop to 20 degrees Celsius, but the geothermal heat in the ground never drops below 5'C. Therefore, this geothermal heat is sucked into the hollow pipe 5, and conduction and
It is converted into warm air by convection (by convection), and is radiated into the water channel -1 of the water guide gutter 3, thereby warming the water channel 4. Therefore, the flowing water in the water channel 13 does not freeze, and leaked water is smoothly flowed down to a predetermined drainage ditch. In particular, since a stainless steel pipe is used as the hollow pipe 5 and the radiation holes 16 are opened horizontally along the inner wall surface of the pipe, highly efficient heat can be generated over the entire width direction of the water guide gutter 3. An exchange action takes place.
不銹鋼管は長期の使用に耐７−る。Rust-free steel pipes can withstand long-term use.

It may also be of a so-called buried type, in which a groove is provided along the vertical direction on the inner wall of the concrete l, and a cover is attached to the groove from the outside or inside in a watertight manner to form a gutter.

る方法がとられる。In addition to the above embodiments, in order to prevent water leakage from horizontally long concrete joints and cracks in the tunnel 1, a water receiving gutter 2 as shown in the front view of FIG. 8 may be used. Once this leakage water has been received, a method is adopted in which the water is introduced into the water guide gutter 3 described above.

リート壁２に固定されている。The water receiving gutter 21 has a pair of left and right sides set to have a predetermined length in the lateral direction, and is installed close to each other, with the length direction along the tunnel length direction. Each water receiving gutter 21 has a rising part 22, a bottom part 23, a partition part 2, and
4 and a mounting portion 25, and is made of hard phenyl chloride covered with a soft vinyl material, and is connected to the anchor bonelet 28 through an elastic water-stopping material 27 made of caulking material 26, rubber, sponge, etc. It is fixed to the concrete wall 2 by a nasoto 29.

流れた水は雨樋間の隙間から導水樋３内に導入される。The pair of water receiving gutters 21 are closed at the end opposite to the proximal end 30 side with an end plate 31, so that leakage water dripping into the water receiving part 32 consisting of the bottom part 23 and the rising part 22 is prevented from flowing toward the proximal end 30 side. The slope is sloped at an angle θ with respect to the horizontal plane so that the water flows into the water, creating a double-drop gutter. Therefore, the proximal end side of the water receiving gutter 21
The flowing water is introduced into the water guide gutter 3 through the gap between the rain gutters.

中に他端部を突出させている。Effects of the Invention As described above, the present invention installs a vertically extending water guide gutter on the inner wall of a $1 structure made of concrete, receives water leakage from the structure 1, and directs this leakage to a predetermined place through the water channel of the water guide gutter. One end of the hollow pipe is opened facing the water channel of the water guide gutter, and the other end of the pipe penetrates the structure and protrudes into the soil of the ground.
