Bridge demolition construction method and equipment thereof

Abstract

The invention provides a bridge demolition construction method and equipment thereof. The equipment comprises a floating mechanism, a clamping mechanism arranged at one end of the floating mechanism, an inclination angle adjusting mechanism arranged at the top of the floating mechanism and a drilling mechanism installed on the inclination angle adjusting mechanism. According to the bridge demolition construction equipment, drilling operation can be stably conducted on the side wall of a water surface pier on the water surface, and after drilling is conducted, blasting personnel can conduct blasting demolition on the pier after charging explosives into a hole. The bridge demolition construction equipment is high in reliability and automation degree, the problem that blast holes are difficult to drill when water surface piers are demolited at present is effectively solved, the construction safety and convenience of workers are improved, and the construction efficiency of the workers is effectively improved.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a bridge demolition construction method and equipment thereof. Background technique [0002] With the accelerated development of my country's basic transportation facilities, due to factors such as congenital design and construction quality defects, changes in use functions, road network re-planning, environmental erosion and vehicle overloading during operation, the structural resistance of bridges has rapidly declined, and the safety of many bridges , reliability and traffic capacity are difficult to meet the growing traffic demand, and the demand for demolition is increasing. [0003] Bridge demolition is a special bridge construction work with great technical difficulty and high safety risks. At present, the construction techniques and methods in the direction of bridge demolition in China are not systematic and perfect enough. For the demolition of water surface ...

Problems solved by technology

[0002] With the accelerated development of my country's basic transportation facilities, due to factors such as congenital design and construction quality defects, changes in use functions, road network re-planning, environmental erosion and vehicle overloading during operation, the structural resistance of bridges has rapidly declined, and the safety of many bridges , reliability and traffic capacity are difficult to meet the growing traffic demand, and the demand for demolition is increasing

[0003] Bridge demolition is a special bridge construction work with great technical difficulty and high safety risks. At present, the domestic construction techniques and methods in the direction of bridge demolition are not systematic and perfect.

For the demolition of water surface bridges, after the bridge deck of the water surface bridge is removed, the bottom of the remaining pier is underwater, especially for a single cylindrical pier, there is no stable ground around it for support, so it is necessary to blast the pier During demolition, the drilling rig cannot stably drill blast holes that meet the blasting requirements on the side wall of the pier, which makes the blasting demolition of underwater pier more difficult, and the construction risks for workers are high
