First, road construction and maintenance

Road repair

In the event of local damage to municipal roads, such as small potholes and network cracks in the road surface, small excavators can be used to remove damaged road surface materials. For example, for the repair of roads around some old districts, small excavators can accurately excavate the broken asphalt or concrete layer to provide conditions for subsequent repair work, and its small body can be flexibly operated in narrow streets without affecting the normal travel of residents.

In road widening projects, the small excavator can assist in excavating the earth at the edge of the road and widening the base part of the road. It is able to carry out excavation operations in the immediate vicinity of the original road, ensuring that the impact on the surrounding traffic during construction is minimised.

Pipe laying and maintenance

There are often a variety of pipes laid under municipal roads, such as sewage pipes, water supply pipes and cable pipes. When these pipes need to be replaced or repaired, small excavators can accurately dig out the trench where the pipe is located without affecting road traffic.

When laying new pipes, small excavators are able to dig according to the designed pipe alignment and depth. For example, in the central area of the city to lay a new power pipeline, small excavators can enter the construction site through a smaller entrance (such as the roadside green belt), digging out the appropriate pipeline trench, to avoid large-scale excavation of the traffic and the surrounding environment.

II. Landscaping

Tree transplantation and planting

In the municipal greening project, it is often necessary to transplant trees. Small excavators can carefully dig out the tree balls without damaging the root system of the trees.

For the planting of new trees, small excavators can dig suitable planting pits according to the size of the trees and soil conditions.

Landscape Shaping

The small excavator can be used to excavate water features such as artificial lakes and streams in parks, street green areas and other municipal green areas. It can be used to excavate natural curved riparian lines in accordance with the requirements of landscape design, creating a realistic natural water feature effect. For example, in the renovation project of a city park, the small excavator excavates a meandering stream along a planned route, adding a dynamic landscape element to the park.

When constructing urban flower beds, flower borders and other landscape vignettes, the small excavator can dig out planting areas of different shapes and depths. It can adjust the depth of excavation and soil texture according to the planting requirements of flowers and plants, providing a good foundation for plant growth.

III. Construction and Maintenance of Municipal Facilities

Sewage Treatment Facilities

Small excavators play an important role in the construction and maintenance of sewage treatment plants. During the construction phase, it can be used to excavate pits for large facilities such as sewage treatment tanks and sedimentation tanks. As these facilities have strict size and depth requirements, the small excavator is able to excavate accurately to ensure the construction quality of the facility. In the maintenance phase, when sewage treatment facilities need to be cleaned or some equipment replaced, the small excavator can carry out discreet excavation operations inside or around the facilities, such as cleaning the sedimentation tanks of accumulated mud.

Refuse disposal facilities

For landfill construction, small excavators are used to excavate the landfill area, including digging pits of varying depths for waste separation. Also, in landfill containment works, it is able to excavate suitable trenches for laying impermeable materials. In the construction of waste incineration plants, small excavators are involved in excavating the foundations of plants and pits for incineration equipment to provide conditions for the installation of equipment and the construction of plants.
