および外側側壁部１１の上端面と面一である。 When constructing a side gutter, first, a groove of a predetermined width and a predetermined depth is excavated at a predetermined position on the ground 2, and the joint members 1 are inserted into the groove at predetermined intervals. Then, a pair of side wall members 3 are arranged between adjacent joint members 1, respectively. At this time, both ends of the outer side wall portion 11 of the side wall member 3 are positioned in the recess 9 of the joint member 1, and the longitudinal end surface of the outer side wall portion 11 is butted against the longitudinal end surface 8a of the protruding plate portion 8. , the lower end surface of the longitudinal end of the outer side wall 11 is butted against the upper surface 6a of the bottom plate 6, and the inner surface of the longitudinal end of the outer side wall 11 is abutted against the outer surface 7a of the side plate 7. Match with. As a result, the side wall member 3 is supported by the joint member 1 in an accurately positioned state, the upper end surface of the outer side wall portion 11 is flush with the upper end surface of the protruding plate portion 8, and the outer surface of the outer side wall portion 11 is flush with the upper end surface of the protruding plate portion 8. is flush with the outer surface of the protruding plate portion 8, and the upper end surface of the inner side wall portion 12 is flush with the upper end surface of the side plate portion 7.
The inner surface of the side plate portion 7 is flush with the inner surface of the side plate portion 7. The side wall member 3 includes an outer side wall portion 11
Since the inner surfaces of both ends of are in contact with the outer surface 7a of the side plate section 7, it does not fall inward, and the outer surface of the outer side wall section 11 is supported by the side wall of the groove on the ground 2. Therefore, it does not fall outward. Therefore, shoring for supporting the side wall member 3 is not required. As described above, a predetermined number of joint members 1
After assembling the side wall members 3 and 3, concrete is cast in place to construct the bottom wall 4, and the opposing side plate parts 7 are assembled.
The side gutter is completed by placing the lid 5 between the upper end surfaces and between the upper end surfaces of the inner side wall portions 12 facing each other. In this state, the top surface of the lid 5 is
and is flush with the upper end surface of the outer side wall portion 11.

大幅に低減できる。 In this way, each of the joint member 1 and the side wall member 3 is extremely lightweight, and can be unloaded from a truck or the like on site or inserted into the premises on the ground 2 using a simple tool such as a chain block. Since it is easy to perform and does not require large-scale equipment such as a crane truck, construction costs can be significantly reduced. In addition, the joint member 1 is very small, and the side wall member 3
Since it is almost flat, it has very good loading efficiency when transported by truck, etc., so transportation costs can be significantly reduced. Moreover, simply by arranging the side wall member 3 between adjacent joint members 1, the side wall member 3 can be reliably supported by the joint member 1 in an accurately positioned state, so that the assembly work of the joint member 1 and the side wall member 3 can be easily performed. Since the construction is easy and at the same time does not require shoring of the side wall member 3, the construction can be carried out reliably in a short time, and from this also the construction cost can be significantly reduced.

に対応できる。(Effects of the invention) As explained above, according to the invention, each of the joint member and the side wall member is extremely lightweight, and can be easily unloaded from a truck on site or inserted into a groove in the ground. This can be easily carried out using simple tools such as a chain block, and large-scale equipment such as a crane truck is not required, so construction costs can be significantly reduced. Further, since the joint member is very small and the side wall member is substantially flat, the loading efficiency is very good when transporting by truck, etc., so that the transport cost can be significantly reduced. Moreover, simply by placing the side wall members between adjacent joint members, the side wall members can be accurately positioned and reliably supported by the joint members, making it easy to assemble the joint members and the side wall members. Since shoring of the side wall members is not required, construction can be carried out reliably in a short time, and from this as well, construction costs can be significantly reduced. In addition, since the bottom wall is constructed with cast-in-place concrete, the bottom wall can be shaped like steps,
It is very easy to make the slope of the bottom wall opposite to the road or to provide an invert on the bottom wall. Further, by slightly deforming the joint member and providing longer and shorter lengths of the paired side wall members, curved portions can be easily accommodated.
