A manipulator includes an end effector, a support member that supports the end effector, and a fixing member provided to the support member and made of a tube-shaped flexible film with a space therein. In the manipulator, a fluid is supplied to the space of the fixing member to inflate the fixing member so that a flexible cover for covering the end effector is fixed to the support member. Accordingly, cleanness of the end effector is restored.

The invention discloses a blasting method of a separated type overpass. The blasting method of the separated type overpass includes the steps that (1) blasting cuts are designed, specifically, the blasting cuts are designed in the arch apex, arch soffits and arch feet of a bridge main arch ring correspondingly, and the blasting cuts are designed in part of stand columns of bridge small arch rings; (2) blasting points are designed, specifically, the multiple blasting points are designed on the bridge main arch ring and the small arch rings; (3) a blasting sequence is set, specifically, the arch apex, the arch feet, the arch soffits and the stand columns of the bridge are blasted in sequence; (4) blasting is performed, specifically, the bridge is blasted in the blasting sequence of the step (3); and (5) site cleaning is performed, specifically, ballast built after bridge blasting is cleaned up, and bridge blasting is completed. By means of the blasting method of the separated type overpass, the weight of a single blasted body can be effectively reduced, and the influence of dismantled bodies on the road surface and an underground pipeline is small; and during construction, a pre-treatment link of blasting construction is omitted, the whole structure of the bridge is not damaged, the traffic safety in the construction process is guaranteed, the whole road closure time is shortened, and the blasting method is safe, reliable and high in efficiency.
