CURB FOR THE ROAD IN WHICH THE INJECTION NOZZLE IS INCLUDED AND SYSTEM FOR CONTROLLING INJECTING FLUIDS FROM THE CURB

摘要

The present invention relates to a curb with an injection nozzle, capable of cleaning a road surface, removing fine dust, mitigating a thermal island effect, and easily melting snow. According to the present invention, the curb with an injection nozzle comprises an injection liquid supply pipe buried in the curb and the injection nozzle coupled to the injection liquid supply pipe to be exposed to the front side of the curb. The curb is cured after concrete is deposited when the injection liquid supply pipe is disposed in a curb mold and a space securing remover is disposed in a portion to be coupled to the injection nozzle and is removed after curing, such that an injection space part is formed. A cover joining part is disposed on the upper part and both sides of the front surface of the curb and the injection liquid supply pipe includes a coupling male screw part coupled to an end part exposed to both sides of the curb to be repetitively disposed in a longitudinal by a pipe joint. In the injection nozzle, a hollow variable nozzle guide is coupled to a hollow fixed nozzle guide protruding perpendicular to the injection liquid supply pipe to be able to be slid, one side of an elastic member is locked to the hollow variable nozzle guide, the other side of the elastic member is locked to the hollow fixed nozzle guide, and a nozzle head is rotatably coupled to the hollow variable nozzle guide.
