Introduction of flexible protective support for roadway net frame shell

The collapsible protective bracket of roadway net frame shell reduces the recovery and maintenance of roadway tunneling and eliminates the hidden danger of closing the door of roadway behind tunneling.Relatively speed up the tunneling into a lane.At the same time, it also reduces the maintenance and recovery of coal mining and greatly reduces the cost.

Characteristics of flexible protective bracket of roadway net frame shell

1. Strong pressure resistance and good primary roadway.

The flexible protective bracket of roadway net frame shell is tightly connected with iron clip, which makes the bracket structure rigorous and the pressure of the bracket is not concentrated.The reason is that the arched arc is similar to the natural arched stress distribution shape of the roadway, and the stress of the supports is relatively uniform, and the compressive resistance of the supports is much stronger than that of the traditional wooden ladder shed and i-steel trapezoidal support.Because the flexible protective support of roadway net frame shell is not easy to be deformed, the anti-pressure is durable: unlike the broken leg of the folding beam like the wooden shed, unlike the curved beam like the i-steel shed, the clamping of the collapse mouth and the leg fall, relatively extend the supporting time, reduce the roadway restoration overturning maintenance, increase the service life.

2. Large safety coefficient and strong disaster resistance.

U yielding protective roadway network frame shell bracket on each side with two canvas for fastening, exact framework, combining beam legs become - body, the overall binding force strong, the gross knocked off not easily, even if there is water, dangling arch tunnel by itself spread compression performance, stent is not easy to sink significantly, and pour out items.

3. Safe and smooth, convenient to walk.

When the support pressure is high and the mining height is not high enough, the original section can still be restored by the bottom drawing method, and the support structure is not easy to change, and the original support strength is almost unchanged.

4. Reduce the ultra-high top and have easy fire protection.

With the use of u-shaped roadway net frame shell, there are fewer times of uplift recovery, and the roof is laid with metal mesh.As long as the primary roadway control the item plate, reduce the top high, relatively reduce gas accumulation and smoke.

5. Small deformation of the supports and easy maintenance of quality standardization.

The compressive strength of the collapsible protective bracket of roadway net frame shell is high, its protective performance is good, and its deformation degree is small
