With the development of economy, the country pays more and more attention to safety production. As urban infrastructure, urban lighting project also puts forward higher requirements for safety production work. Basic engineering is also very important in the whole process of urban lighting project. The safety management of foundation construction cannot be ignored, and grasping the key points of safety management is conducive to doing a good job in safety management. So what should we pay attention to in the basics of street lights? The following will explain to you: 1.1 When conditions permit, the prefabricated reinforced concrete foundation is preferred, and the existing reinforced concrete foundation is used when the prefabricated foundation is not applicable due to the obstacles of nearby pipelines, the limitation of the buried depth, or the influence of geological conditions. 1.2 If the natural environment has a corrosive effect on the foundation, the foundation should take anti-corrosion measures in accordance with the 'Code for Design of Industrial Buildings Anti-Corrosion' (GB50046). 1.3 The foundation design shall take into account the influence of seasonal changes in the groundwater level. The foundation weight and soil weight below the groundwater level should be considered according to the floating weight: the floating weight of the general concrete foundation is 12kNAn3; the floating weight of the reinforced concrete foundation is 14kN/m³; the floating weight of the soil should be 8kN/ m³~1 IkN/m³. 1.4 The burial depth of the foundation should be greater than 0.5m. In the seasonally frozen land area, the local foundation soil A should be greater than the standard freezing depth of the soil when it has frost heaving properties. Very Basic Design Specifications. 1.5 - Natural foundation is generally used. When the foundation is placed below the groundwater level or the foundation is weak, a cushion should be laid or other measures should be taken. In general, the F cushion can be grouted with concrete or paving stones. If the conditions for grading and excavation are not available, the surrounding of the foundation pit can be supported. After the support, manual or mechanical excavation is adopted. During the excavation process, attention should be paid to strengthening the monitoring of the soil around the foundation pit. If abnormal soil is found, the operation should be stopped immediately. . The soil excavated in the foundation pit shall be cleared and transported in time, and no soil or heavy objects shall be piled up within 1.5 meters around the foundation pit. When manual excavation is performed without grading, a temporary ladder or a temporary ramp should be set up around the foundation pit to facilitate the passage of people or to evacuate the foundation pit quickly in the event of an emergency. solar street light,solar street light manufacturer,high pole light,high pole light manufacturer,street light,street light manufacturer,street light,street light manufacturer,
