The fountain nozzle provided on this nozzle branch pipe is exposed on the top surface of the block, a convex portion is formed on one side, and a concave portion is formed on the opposite side so that the convex portion just fits. A block with a fountain nozzle is known which is formed and placed, and the projection and the recess are fitted with a packing or the like interposed therebetween (column 1, column 1, bottom row to column 2, row 4). However, in this block, since the convex and concave portions are made of concrete, there is a possibility that it is difficult to obtain a sufficient connection strength.

Therefore, a steel pipe is buried in a snow-absorbing block, and a male cylinder and a female cylinder are provided at the end of the steel pipe. The inner surface of the male cylinder and the outer surface of the female cylinder are machined, It is known that a male cylinder is inserted into a cylinder to join a block, and high dimensional accuracy can be obtained by machining, so that connection with excellent watertightness can be performed.

However, it is difficult to directly machine the end of a steel pipe. Generally, male and female cylinders are separately formed, and after these cylinders are machined, they are fixed to the steel pipe by welding or the like. Since two cylinders are used in one block, each machining operation and welding operation to the steel pipe after the machining operation occur, so that an increase in cost is unavoidable.

Further, in the block with the fountain nozzle, since the cross-sectional shape of the convex portion and the concave portion is formed in a trapezoid, when a force acts on the block in a direction in which the convex portion is removed, a gap is formed between the convex portion and the concave portion. And water leakage may occur. In addition, joints must be provided between the blocks to absorb the contraction of the blocks after installation and the slight bending at the connection part, but it is difficult to set the joint spacing correctly in the connection with the above watering nozzle. .

Accordingly, the present invention has an object to provide a snow-absorbing block connection structure and a snow-absorbing block which are excellent in watertightness and can reduce the cost, and additionally, a snow-absorbing block in which the joint interval can be easily set. It is an object of the present invention to provide a connection structure and a snow removal block.
