How to control hazard when using shotcrete machine

As we all know, shotcrete machine has an irreplaceable role in bolting and shotcreting in. Since the shotcrete machine four elastic clamping structure, solid and stable, good sealing; a single point of elastic pressing reshaping the structure of products, simple science, can always maintain a reasonable compression force, reducing machine next to the dust, and easy maintenance disassembly , the vulnerability of long life, etc., are widely used in construction, mining, tunnel, culvert construction work and other places. In construction operations inevitably will encounter a variety of unexpected situations, we must first protect their own safety, today to talk about the shotcrete machine when using the hazard control:

First, the aspect of electric shock:

1. shotcrete machine explosion in good condition;

2. shotcrete machine load suspension cables and feeling good;

3. shotcrete machine explosion-proof switch in good condition;

4. after spraying is finished switch power failure, prevention of unexpected start;

5. shotcrete machine install location (tricking impact).

Second, the transport:

1. shotcrete machine and safe distance from the track;

2. the safety distance between people (to prevent accidental collision, accidental injury) on the manner in which the use of shotcrete feeding, automatic feeding or artificial feeding ? Material on the ground or in the mine car ? Oblique lane drift transportation or transportation?

3. shotcrete machine fixed way.

Third, the water supply for the wind:

1. wind, water pipe joints banding is reliable;

2. notes with wind pressure spray tube when?

3. good condition spray tube, anti-burst problem;

4. spray pipe requirements (diameter, material, wall thickness, etc.).

Fourth, spraying areas:

1. the top wall rock;

2. supporting the case;

3. surface and spray from the spray pipe, anti-rebound wounding;

4. spraying material requirements (gravel particle size is too easy to blast tube plugging, tidal spray material, the amount of accelerator meet the requirements, etc.);

5. hand spray can‘t be around someone within 2 meters;

6. feeding station and the contacts between the hand spray;
