  By the way, in the snow removal block 33 described above, a male pipe portion 35a, which is one end portion of the water flow pipe 35, is projected at one end portion of the snow removal block 33, and at the other end portion of the snow removal block 33. The female pipe part 35b which is the other end part of the water flow pipe 35 is recessed. Therefore, the connection between the adjacent snow removal blocks 33 is performed by connecting the male pipe part 35a of one snow removal block 33 to another snow removal block. This is done by fitting and connecting to the 33 female pipe portions 35b.

  However, this conventionally proposed snow removal block 33, when actually connecting the snow removal blocks 33, slightly separates one snow removal block 33 suspended by a heavy machine such as a crane from other snow removal blocks 33. Next, one snow removal block 33 is placed on the other snow removal block 33 side so that the male pipe portion 35a of one snow removal block 33 is inserted into the female pipe portion 35b of the other snow removal block 33. However, it is troublesome to move the heavy snow-melting block 33 in this manner.

  In addition, a problem has been pointed out in the work of replacing one damaged snow-dissipating block 33 among a plurality of snow-dissipating blocks 33 connected to each other.

  Specifically, for example, as illustrated in FIG. 14, an operation of exchanging the central snow removal block 33 </ b> A among the three snow removal blocks 33 </ b> A, 33 </ b> B, 33 </ b> C connected to each other will be described as an example.

  First, as shown in FIG. 15, the blade of the cutting device is inserted from the boundary between the center snow removal block 33A and the left and right snow removal blocks 33B and 33C, and the male pipe portion 35a of the center snow removal block 33A and the left side The male pipe part 35a of the snow removal block 33B is cut, and the snow removal block 33A at the center is lifted and removed.

  Subsequently, as shown in FIGS. 16 and 17, the concrete portions (shaded portions in FIG. 16) of the left snow removal block 33 </ b> B and the right snow removal block 33 </ b> C are shaved to expose the end portion of the water pipe 35. As shown in FIG. 18, an extension pipe 37 having a thread groove 37a formed on the peripheral surface is welded to the end of each exposed water pipe 35. At this time, in the water flow pipe 35 exposed to the right snow extinguishing block 33C, the extension pipe 37 is welded after the female pipe portion 35b is cut.

  Subsequently, as shown in FIGS. 19 and 20, a replacement snow-melting block 33D (snow-melting block) having a structure different from that of the snow-breaking blocks 33A, 33B, 33C separately prepared between the left and right snow-melting blocks 33B, 33C. 33A, 33B, and 33C are different in the end structure of the water pipe 35). The snow-removing block 33D for replacement has projecting ends of the water pipe 35 from both ends, and a thread groove 35c is formed on the peripheral surface of the projecting portion. Is fitted with a tubular coupling body 36 (coupling) in advance.

  Subsequently, as shown in FIG. 21, the connecting body 36 is screwed into the extension pipes 37 of the left and right snow-melting blocks 33B and 33C until they are fitted, and then the left and right sides as shown in FIG. Concrete 38 is placed between each of the snow-melting blocks 33B and 33C and the snow-melting block 33A in the center to complete.

  As described above, the conventionally proposed snow extinguishing block 33 is a work for cutting a concrete portion as described above, a work for cutting an unnecessary portion (female pipe portion 35b) of the water flow pipe 35, and an extension to the cut portion. It is cumbersome because it requires welding work of the pipe 37 (it is difficult to do quickly on site), and a snow-breaking block for replacement must be prepared separately, resulting in high costs. There are problems.
