随着航道整治工程水下爆破施工任务的增多,对提高施工效率及降低成本控制的要求也愈来愈高;遵循经济实用的原则,对原有落后设备进行再次改造是势在必行的举措;改造后的施工效率明显提高和施工成本明显降低,设备的使用寿命得到延长。 With the increasing number of underwater blasting construction tasks of waterway regulation works, the requirements for improving construction efficiency and reducing cost control are also getting higher and higher. Following the principle of economy and practicality, it is imperative to reconstruct the original backward equipment again ; After the transformation of the construction efficiency was significantly improved and significantly reduce the cost of construction, equipment, service life has been extended.
