Description

Positioning auxiliary device for underwater boulder reef explosion

Technical Field

The utility model belongs to the technical field of the positioning device technique and specifically relates to a location auxiliary device that is used for boulder to explode reef under water.

Background

The dredging of the harbor pool and channel of the water transportation engineering often needs the excavation of hard substrate or the blasting excavation of reefs, because of different geological causes, boulders often appear, and the underwater boulder reef explosion is a difficult problem of underwater reef explosion construction.

When the water drilling machine is difficult to position and drill and blast, underwater naked blasting is also adopted, but the efficiency is low, and the ecological environment is seriously influenced. The construction of water reefs is generally to drill and blast reefs higher than the designed water bottom elevation and to excavate and remove the reefs after water depth measurement, geological exploration and surface excavation. However, because the underwater reefs are distributed in the shape of a boulder, the underwater reefs are required to be positioned on the boulder, a steel sleeve is required to be arranged on the boulder, drilling operation is required to be carried out, the difficulty is high, and the situations that the steel sleeve is unstable on the rock surface, the sleeve and a drill bit slide, equipment is damaged, and normal construction cannot be carried out often occur.
