about traffic lights installed? Installation and construction process: positioning motorized. Ditching machine; Buried pipe rarr reversing light foundation frame; Laying cable; Insulation test report. Lights installed Rarr control system equipment installation. The experiment and debugging; Self-checking rarr completion inspection and acceptance of construction methods: 1. Locate the lamp 2. Trench buried pipe: foot stone pavement center distance road 50 centimeters, dig a 30 cm wide and 50 cm deep cable pipe embedded groove, and according to the construction drawings corresponding cable pipe buried. With the nearest distance between two observation Wells and perpendicular to the center as a benchmark of the road, through the pipe should be excavated a 30 cm wide and 50 cm cable pipe embedded deep groove 3, and casting light foundation: metal construction according to party a with light prefabricated foundation drawing of foundation pit excavation corresponding size, and the metal antirust processing components. Coating quality should be consistent with existing national standards 'vickers and street lamp manufacture company metal coverings and other related mulch microhardness test' ( GB / T9700) , the general principles of the thermal spraying metal parts surface pretreatment ( GB / T11373) And the current industry standard 'hot dip aluminized steel and iron process and quality inspection' ( ZBJ36011) Behind the relevant provisions of the traffic lights should not have colored lights or signs, which easily confused with traffic lights. Under the overpass intersection, motor vehicle lamp can be installed on the shell or the right side of the entrance driveway. If there are two you under the overpass, the opposite of the right side of the lights should be installed at the other side of the intersection. In traffic lights around the range of related reference axis, should not have affected the truthfulness of the traffic lights obstacles, in about 50 meters of the side of the road from traffic lights should not be an obstacle to the traffic lights.
