Which sub item does the foundation of outdoor street lights belong to?

The foundation of outdoor street lamps belongs to the electrical and intelligent engineering sub-project of construction engineering.

Outdoor street light foundation refers to the foundation work carried out in order to support and fix outdoor street lights. It is usually constructed of concrete, which is used to bear the weight of street light poles and the force of the external environment, ensuring the stability and safety of street lights.

In construction engineering, electrical and intelligent engineering is an important sub-item, which involves the design, installation and maintenance of electrical equipment and systems inside and outside buildings. As a part of outdoor electrical equipment, the foundation of outdoor street lights belongs to the category of electrical and intelligent engineering.

The construction process of the outdoor street light foundation includes the following steps:

1.Design: According to the type and requirements of the street lamp, determine the size, shape and depth of the street lamp foundation. The design should take into account the height, weight, wind pressure and other factors of the street lamp to ensure the stability of the foundation.

2.Foundation treatment: Before construction, the foundation of the foundation needs to be treated, including cleaning, leveling and reinforcement. The treatment of the foundation can improve the bearing capacity and stability of the foundation.

3.Template making: According to the design requirements, make a template suitable for the foundation of street lights. The formwork should be made precisely to ensure that the shape and size of the foundation meet the design requirements.

4.Pouring concrete: Concrete is poured inside the formwork to ensure that the concrete fills the formwork adequately, and a vibrator is used to vibrate to remove air bubbles and voids in the concrete.

5.Curing: After the concrete is poured, it needs to be cured to ensure the strength and stability of the concrete. The curing time is generally 7-14 days, during which it is necessary to keep the foundation moist and avoid the influence of external forces.

The construction of the foundation of outdoor street lights needs to be carried out in strict accordance with the relevant specifications and standards to ensure the quality and safety of the foundation. During the construction process, it is necessary to pay attention to the safety of the construction site, reasonably arrange the construction schedule, ensure the quality and progress of the construction, and ensure the safety of workers.

Superstructure: bearings, prefabricated slabs, bridge deck pavement, expansion joints, hinge joints, continuous joints Ancillary structures: anti-collision guardrails, drain pipes, lap plates, cone slopes, slope protection, and platform back fill maintenance.

In the bridge maintenance inspection, new and precise measuring instruments are used, such as the determination of defects and elastic modulus of structural materials by acoustic measurement; Inspect the crystal structure of the steel with a hand-held metallographic camera so that it can be reinforced as soon as possible, so as to prolong the service life of the bridge.

Bridge engineering has always been under the comprehensive influence of production development and various scientific and technological progress, following the principles of applicability, safety, economy and aesthetics, and constantly moving forward.

The construction unit has a large amount of information, and one of the functions of the sub-project division is to ensure that the construction unit's data is compiled in a clear and organized manner.
