By the way, in order to form a snow-melting road using the snow-melting blocks, it is necessary to connect the snow-melting blocks one after another. Mitsuko Sho 55-134
The snow-dissipating block connecting means shown in No. 59 has a concavo-convex portion centered on the water supply pipe at the end of the block body and is fitted with both. However, since the fitting part also serves as the connection of the water pipe, the fitting part must be in a state close to close fitting in order to secure watertightness, and the block itself has a considerable weight. Therefore, the connecting work becomes very complicated.

In connection with the snow-dissipating blocks disclosed in Japanese Patent Laid-Open No. 60-25831, the water pipes protruding from the ends of the block bodies are butted together, and the butted portions are joined together by a connecting member (a split cylinder with an inner surface covered with rubber). Body). Further, at the time of the connection, a concrete plate is laid under the connection part so that the connection part does not bend or break due to the weight of the vehicle passing above, and the end of the block body is placed on the concrete plate. The structure is adopted.

However, the work of laying a concrete plate at a predetermined design position in the burying groove of the snow-melting block formed on the road surface requires the measurement of the laying position, and if it is not provided as designed, the snow-melting will occur. Since it does not correspond to the connecting portion of the block body, accuracy is required and it is complicated. Furthermore, if design changes are forced due to various factors that occur in the field, there is a drawback that it is not possible to respond quickly. Therefore, the present invention proposes a snow-dissipating block in which the water pipes can be easily connected and the connecting portion can also be provided with appropriate strength.
