【Example】

 <First Embodiment shown in FIGS. 1 to 3> In this first embodiment, first, two vinyl chloride short tubes 1 and 2 are connected by a vinyl chloride elbow 3 and these short tubes made of vinyl chloride are connected to each other. The outer ends of the pipes 1 and 2 are connected to sockets 5 and 6 having a seal packing 4 made of styrene butadiene rubber provided on the inner surface thereof to form an L-shaped modified block joint body 7. A sprinkling nozzle 9 is connected to an intermediate portion of one of the short pipes 1 made of vinyl chloride 7 through a branch pipe 8 in an upright state.

The L-shaped block joint body 7 is formed inside a deformed concrete block 10 having the following shape, and receiving ports 5 and 6 at both outer ends thereof are opened to both end faces of the deformed concrete block 10. The sprinkling nozzle 9 is buried in a state where it is exposed and the end face of the sprinkling nozzle 9 is substantially flush with the upper surface of the deformed concrete block 10.

The above-described deformed concrete block 10 has a trapezoidal shape in the upper half of the cross section and a rectangular shape in the lower half, and a step 12 on both sides of a continuous portion of the upper half of the trapezoid and the lower half of the rectangle. , 13 are formed, and are formed with reinforcing bars 14.

<Second Embodiment shown in FIGS. 4 to 6> In this second embodiment, first, three short pipes 21, 22, and 23 made of vinyl chloride are connected by a T-shaped pipe joint 24 made of vinyl chloride. Further, at the outer end of each of the short pipes 21, 22, 23 made of vinyl chloride, seal ports 25 made of styrene-butadiene rubber are connected on the inner surface thereof. A joint main body 29 is formed, and a watering nozzle 31 is connected to a central portion of the T-shaped pipe joint 24 in the T-shaped modified block joint main body 29 via an upright branch pipe 30.

The T-shaped modified block joint main body 29 is provided inside a T-shaped modified concrete block 32 described below, and receiving ports 26, 27, and 28 at all outer ends thereof are opened at three end surfaces of the concrete block 32. The sprinkling nozzle 31 is buried in a state where it is exposed and the mouth end surface of the sprinkling nozzle 31 is exposed to be substantially flush with the upper surface of the deformed concrete block 32.

The above-mentioned T-shaped deformed concrete block 32 has a trapezoidal upper half in cross section, a rectangular shape in the lower half, and a step on both sides of a continuous portion of the upper half of the trapezoid and the lower half of the rectangle. The parts 33 and 34 are formed, and are formed with the reinforcing bar 35.

<Third Embodiment shown in FIGS. 7 to 11> In this third embodiment, first, a sealing pipe 37 made of styrene-butadiene rubber is provided around the inner surface of both ends of one short pipe 36 made of vinyl chloride. 38 and 39 are connected to form a linear shaped water-blocking deformed block joint body 40.

[0015] The linear shaped irregularly shaped block joint body 40 for water supply is inserted into a linearly shaped irregularly shaped concrete block 41 described below, and receiving ports 38, 39 at both outer ends thereof are provided at both end surfaces of the irregularly shaped concrete block 41. And buried in an open state.

The above-mentioned straight-shaped irregularly shaped concrete block 41 has a trapezoidal upper half in cross section and a rectangular shape longer in a lower half, and step portions 42 on both sides of a continuous portion of the upper half of the trapezoid and the lower half of the rectangle. , 43 are formed with a difference between the height of the left half and the height of the right half.

Reference numerals 46 and 47 in the drawings denote construction inserts. Also, the water-block shaped block joint body can be made of metal such as stainless steel.

The deformed block joint of the snow-absorbing block for the snow-absorbing road of the above embodiment is formed by using a connecting pipe joint 50 prepared in advance as disclosed in, for example, JP-A-2001-146989. (See FIG. 12).

First, a buried groove for laying the snow-absorbing road snow-blocking block 51 is excavated on the road surface, and the bottom surface of the buried groove is crushed and flattened. The deformed block joint 52 of the snow-absorbing road block according to the present invention is arranged at a necessary location between the snow-absorbing blocks 51 for the snow-absorbing road.

After that, in the snow-absorbing block 51 for the snow-absorbing road and the modified block joint 52 of the present invention, both ends of the connecting pipe joint 50 are inserted into both receiving ports which face each other. The outer peripheral surface of the connecting pipe joint 50 and the inner peripheral surface of the seal packing are brought into a press-contacted state so as to be in a connected state, and a joint material 53 such as elastite, putty rubber or cement milk is provided in a gap between the connected end faces. After that, the buried trench is backfilled, and then asphalt and other pavement work is performed to complete the construction work.

[Effect of the invention]

 Since the deformed block joint of the snow removal block for a snow removal road according to the present invention has the above-described configuration, the snow removal block 51 for a snow removal road and the deformed block of the present invention are connected as described above. In some cases, as is apparent from FIG. 12, the V-shaped gap 64 (see FIG. 13), which is generated in the conventional example, does not occur, and the inconvenience such as complicating the construction is completely eliminated. Is played.
