Description

Technical Field

[0001] The utility model relates to a street lamp mounting base, specifically to an improved road greening landscape street lamp mounting base, which is mainly used to support and fix lamps, can keep the lamps stably placed on the ground or other positions, prevent them from shaking or tilting, ensure the normal operation of the lamps and achieve the expected lighting effect, and can also beautify the surrounding environment, belonging to the field of landscape decoration technology. Background Art

[0002] As we all know, some landscape lights need to be installed in streets or landscape areas. When installing landscape lights, landscape light mounting bases are often needed to install and limit the landscape lights. At present, the landscape lights on the market have a single design: the design of some landscape light mounting bases is relatively simple, lacking innovation and diversity. This makes the landscape lights in cities and public places look similar and lack personalized features.

[0003] At present, in some ecological red lines, national wetland parks, and animal conservation areas, the environment is extremely complex. Construction shall not involve large-scale excavation, encroachment on the water body of Dianchi Lake, pollution of the water body, or destruction of the ecology. The construction process must be ecological, environmentally friendly, and low-interference. Due to the particularity of the project, the location, height, and style of ground structures such as street lights will be adjusted according to the different requirements of different departments and locations. At present, the more common lamp holder installation devices used on the market require ground excavation first. According to the location of the street lamp installation, excavation is first carried out at the installation location. After the excavation forms a foundation pit for the street lamp installation, the construction personnel need to support the formwork in the foundation pit. After the support is completed, concrete is poured. The concrete structure of the lamp holder is formed by pouring concrete to fix the street lamp. This traditional method has the following technical defects in the specific use process:

[0004] On the one hand, during the excavation of the foundation pit, the soil, stones, sand, gravel, or pebbles produced need to be transported to other places for centralized stacking by construction workers, which is time-consuming and labor-intensive, slows down the construction, and is also costly;

[0005] On the other hand, the above-mentioned traditional construction method has complicated construction operations and a long construction period. After the concrete is poured, it needs to be maintained. The maintenance period is long. During the maintenance process, if there is improper protection, it will be damaged, resulting in the need for rework.

[0006] On the other hand, it is difficult to carry out maintenance in the later stage. When the street lamp is installed and put into use, due to long-term use, when the street lamp is damaged or the line fails and needs to be repaired, since the lamp holder is directly cast in concrete and formed in one piece, it is often difficult to repair the street lamp. It is even necessary to chisel the concrete lamp holder and replace it again, which is costly, time-consuming and labor-intensive. Concrete lamp holders are usually made of concrete materials, so they are relatively heavy. This makes it more difficult and expensive to install and move the lamp holders. When it is necessary to rearrange or replace the lamps, moving or adjusting the concrete lamp holders may require additional manpower and equipment. In short, it is often inconvenient.

[0007] Therefore, in order to reduce rework and ensure the construction period, the key to solving the above technical problems is to study an improved road greening landscape street lamp installation limit device that is reusable, easy to change position, and ensures construction progress and quality. Summary of the invention

[0008] In view of the many defects and shortcomings existing in the above-mentioned background technology, the utility model has made improvements and innovations thereto, and aims to provide a lamp holder with a simple structure, novel and reasonable design, flexible and convenient use, which can be installed with different models and sizes according to actual needs, can be reused, is easy to change positions, ensures construction progress and quality, and is convenient and quick to maintain; through prefabrication in the factory, the quality is guaranteed, the labor is reduced, and the progress is fast; it can be installed whenever it is used, and will not be abandoned; more importantly, the earth or soil or sand, gravel and pebbles from the excavated foundation can be filled into the adjustable embedded box of the utility model, which reduces the transportation and processing of earth, reduces the labor intensity of the operator to the greatest extent, and makes it easy to grow grass, beautify the surrounding environment, and make the greening beautiful.
