Description

Technical Field

[0001] The invention relates to the technical field of municipal overhead pole removal construction, and in particular to an overhead pole line underground construction device. Background Art

[0002] With the development of society, the installation method of overhead poles and wires used in many cables such as communication cables and power cables is no longer appropriate. It occupies a lot of urban space, restricts the development of the city, and also poses great safety hazards. Based on this situation, many cities have taken action, that is, the underground engineering of overhead poles and wires, which mainly replaces the overhead poles and wires with cables running underground. This process has many construction links, among which the removal of overhead poles and wires is one of the key tasks. Generally, overhead poles are mainly cement poles. In the removal process, due to the hardening of urban roads, it is not suitable to use the excavation removal method, so the removal of cement poles mainly involves first hammering the cement blocks at the roots close to the ground, and then cutting the steel bars with hydraulic pliers, electric saws and other tools, and finally transferring the cut cement poles by crane. However, due to different urban development conditions, some cement utility poles in the old city are arranged in narrow alleys, which are not convenient for cranes to enter. Many workers need to work together, which consumes a lot of manpower and material resources. Due to historical reasons, there are still quite a large number of such cement utility poles. Based on this situation, we specially organized personnel to conduct research and designed a device for removing overhead poles that can be used in narrow alleys. It effectively solved the problems encountered in the underground construction of overhead poles in the old city, and helped the old city to have a new look. Summary of the invention
