Description

Mold for foundation construction of bridge streetlights and streetlight foundation construction method using the same {mold for the construction of bridge streetlight foundation and the construction method of streetlight foundation using it}

The present invention relates to a formwork for streetlight foundation construction of a bridge and a streetlight foundation construction method using the same. More specifically, it relates to a standardized formwork for streetlight foundation construction installed on the side of a bridge, installing a standardized formwork, and punching cement into the formwork. Therefore, the present invention relates to a formwork for foundation construction of bridge streetlights that simplifies construction of streetlights on the side of a bridge and a streetlight foundation construction method using the same.

In general, street lights refer to lighting facilities installed along streets for the safety and security of street traffic. Currently, in Korea, street lighting refers to road lighting installed on public roads with a width of 12 m or more. In a broad sense, it includes street lights, bridge lights, tunnel lights, and pedestrian lights on general roads, and in a narrow sense, it only includes street lights on general roads. It means.

Street lights must ensure road surface illumination that does not interfere with the passage of pedestrians and vehicles, and the street light structure itself must ensure structural safety against external forces. In addition, streetlights must be beautifully designed considering the aesthetics of the city, and have a system that is easy to maintain and install.

Meanwhile, conventional streetlights are structured in such a way that streetlight poles are installed on a basic structure. In other words, it consists of a structure in which a basic structure made of pre-fabricated concrete, etc. is buried in the ground, and a streetlight pole is installed by being coupled to the upper side of the basic structure through anchor bolts, etc.

In addition, when installing street lights, the autonomous district currently installs all structures in the form of stilts, completely burying the foundations that secure them and connecting them to the pillars 20 to 30 cm below the ground, so that only the straight circular pillars without any protruding parts are visible on the sidewalk. We are providing guidance on construction using the ‘completely buried support installation method’. In this case, especially once the streetlight is installed, it is impossible to adjust the position and angle of the streetlight, so it needs to be firmly fixed so that the position and angle do not change after the streetlight is first installed.

Therefore, since streetlights installed on conventional bridges are installed with the basic structure for streetlights embedded in the top of the bridge, a certain portion of the width of the top of the bridge must be used as space for streetlights, and a road of a certain width must be secured for vehicle traffic. A problem arises where the available lanes are reduced by the installation space for streetlights.

In other words, in bridges installed for smooth passage of vehicles, problems arise such as widening the width of the bridge or reducing the number of lanes due to the space for installing streetlights.

As an example of a conventional technology to solve this problem, there is a method of constructing streetlights by installing a foundation structure on the outside of the bridge.

However, it is installed on the ground or on the side of the bridge. When installed on the ground, there are problems with restrictions on the construction location or increased construction period and construction cost. When installed on the side of the bridge, construction of the foundation structure is required. Since a series of processes such as assembling, installing, and disassembling the form must be performed repeatedly, there is a problem that the construction period and construction cost increase.

Therefore, there is a need for a construction method for bridge streetlights that can secure the upper surface of the bridge as much as possible and is easy to construct.

The problem to be solved by the present invention is to provide a formwork for the foundation construction of a bridge streetlight that can fully utilize the upper surface space of the bridge by installing the streetlight foundation on the side of the bridge and a streetlight foundation construction method using the same.
