How to pour the foundation of road Traffic Lights

Traffic Lights Factory Video
Whether the road Traffic Lights foundation is well laid is related to issues such as whether the equipment is robust in the later use process, so we must do this work well in the process of preparing the equipment in the early stage:
1. Determine the position of the standing lamp: survey the geological conditions, assuming that the ground surface is 1.2m2 is soft soil, then the excavation depth and height should be deepened; at the same time, it must be confirmed that there are no other facilities (such as cables, pipes, etc.) below the excavation position, road Traffic Lights There is no long-term shading object on the top, otherwise the position should be changed appropriately.

2. Reserve (excavate) a 1.3-meter pit that meets the specifications at the position of the Traffic Lights on the vertical road, and perform positioning and pouring of the embedded parts. The embedded parts are placed in the center of the square pit, one end of the PVC threading pipe is placed in the middle of the embedded parts, and the other end is placed in the battery storage place. Pay attention to keep the embedded parts, the foundation and the original site on the same level (or the top of the screw and the original site on the same level, depending on the site requirements), and one side must be parallel to the road; in this way, it can be ensured that the light pole is erected and regular.

Not skewed. Then it is poured and fixed with C20 concrete. During the pouring process, the vibrating rod should not be stopped to vibrate to ensure the overall compactness and robustness. 
3. After the construction is completed, clean up the residual mud on the positioning plate in time, and clean the impurities on the bolts with waste oil.
4. During the condensing process of the concrete, regular watering and maintenance are required; the chandelier installation can only be carried out after the concrete is completely condensed (generally more than 72 hours).

In order to do a good job in the foundation of the road Traffic Lights, in addition to the normal pouring work, it is very important for us to maintain the work in the later stage. Regular watering and maintenance are required to ensure the quality of the construction.
