Description

Drilling and rescue system

Technical field

The present invention relates to drilling equipment, and more particularly to a drilling and rescue system.

Background technique

In recent years, children’s falling accidents have occurred frequently. Although various rescue methods have been carried out every time, they are not satisfactory in terms of process and results.

At present, the commonly used rescue method is to excavate the tunnel around the shaft for rescue. This method is simple to operate, and several excavators can be used; the disadvantages are also obvious:

(1) The amount of earthwork is huge, and at the same time as excavation, it is necessary to constantly transport the soil;

(2) The speed is slow, and the soil needs to be transported step by step from the inside to the outside;

(3) The risk is high. The large excavator itself has a large tonnage and heavy weight. It is easy to cause the earth around the rescue to collapse due to crushing during operation, thus causing secondary disasters;

(4) The amount of work after the aftermath is large, and the large pit backfilling work formed by excavation is large;

(5) Waste of resources, large pits formed by excavation, if not backfilled, resulting in huge waste of land resources.
