Abstract

PROBLEM TO BE SOLVED: To provide a side ditch, by which a slide and an overturn can be prevented, the quantity of excavated materials can be decreased, labor, the time and labor cost can be reduced and earth pressure applied to a wall surface can be lowered. SOLUTION: The side ditch is composed of an inverted U-shaped sectional side ditch body 10 with a water way and an earth-pressure reducing plate 20A projected and formed to the outside to an intermediate section between an upper end and a lower end on the external wall surface of the side ditch body 10. Accordingly, the side ditch resists horizontal force applied from the horizontal direction and turning moment, and a slide and an overturn can be prevented. Since a ground surface in a section lower than the earth-pressure reducing plate 20A need not be excavated, the quantity of excavated materials can be lowered, and labor, the time and labor cost can be reduced. Earth pressure received by a wall surface is dispersed into one received by the wall surface in the section lower than the earth-pressure reducing plate 20A and one received by the wall surface upper than the earth-pressure reducing plate 20A, and decreased. Consequently, earth pressure can be made smaller than one received by the wall surface in a time when the earth-pressure reducing plate 20A is not formed.

As shown in FIG. 8 (I), the side groove 101 has an inverted U-shape in cross section having a water channel. The side groove 101 of the conventional example I is
There is a drawback that when a lateral force is applied, sliding and overturning occur easily. Then, as shown in FIG. 8 (II), a side groove 201 described in Japanese Patent Application Laid-Open No. 10-292470 has been devised. The side groove 201 has a rib 202 formed below the side groove 101. According to the side groove 201, even when a horizontal force and a rotational moment due to a lateral force are applied,
Since the ribs 202 are pressed down by the soil above the ribs 202, slipping and tipping can be prevented.

According to the first aspect of the present invention, the earth pressure reducing plate projects outward from the outer wall of the gutter main body, and the earth pressure reducing plate is held down by the soil above the earth pressure reducing plate. It is strong against horizontal force and rotational moment due to the force applied from the lateral direction, and can prevent sliding and falling. In addition, since the earth pressure reducing plate projects outward from an intermediate portion between the upper end and the lower end of the outer wall of the gutter main body, it is not necessary to excavate the ground below the earth pressure reducing plate. The amount can be reduced and labor, time and labor costs can be reduced. Further, since the earth pressure reducing plate is formed at an intermediate portion between the upper end and the lower end of the gutter main body, the earth pressure received by the wall surface is lower than the earth pressure received by the wall surface below the earth pressure reducing plate. It is dispersed and reduced by the earth pressure received on the wall surface above the lightening plate. Therefore, the earth pressure can be reduced as compared with the earth pressure received on the wall surface when the earth pressure reducing plate is not formed. According to the invention of claim 2, since the earth pressure reducing plate is formed over the entire length of the gutter main body,
The earth pressure applied to the wall surface can be further reduced.

According to the first aspect of the present invention, the earth pressure reducing plate projects outward from the outer wall of the gutter main body, and the earth pressure reducing plate is pressed downward by the soil above the earth pressure reducing plate. Therefore, it is strong against horizontal force and rotational moment due to the force applied from the lateral direction, and can prevent sliding and overturning. In addition, since the earth pressure reducing plate projects outward from an intermediate portion between the upper end and the lower end of the outer wall of the gutter main body, it is not necessary to excavate the ground below the earth pressure reducing plate. The amount can be reduced and labor, time and labor costs can be reduced. Further, since the earth pressure reducing plate is formed at an intermediate portion between the upper end and the lower end of the gutter main body, the earth pressure received by the wall surface is lower than the earth pressure received by the wall surface below the earth pressure reducing plate. It is dispersed and reduced by the earth pressure received on the wall surface above the lightening plate. Therefore, the earth pressure can be reduced as compared with the earth pressure received on the wall surface when the earth pressure reducing plate is not formed. According to the second aspect of the present invention, since the earth pressure reducing plate is formed over the entire length of the side groove, the earth pressure applied to the wall surface can be further reduced.
