Further, described gear cash net is rhombus net.
Further, described canopy lower limb is connected by two single u-shaped steel and forms, and two single u-shaped steel are connected by fastening clamp.
Further, described back timber is U-shaped steel, the half of a length of span length of described back timber.
Further, described many anchor poles include strengthening anchor pole and many support anchor rods, and described many support anchor rods are equidistant
From distribution；Described reinforcement anchor pole is located between adjacent two support anchor rod, and is positioned at the central region in tunnel, and described back timber is remote
It is connected with described reinforcement anchor pole from the one end in goaf.
Further, described back timber has also set up monomer liquid more than the position in the range of top board work surface periodic weighting step pitch
Pressure pillar, with strengthening supporting.
Further, described supporting construction also includes that at least two anchor cables, each anchor cable are located at the top in tunnel and are positioned at
Between two adjacent anchor poles.
A kind of method for protecting support for gob side entry retaining, comprises the following steps:
Thering is provided one to protect the supporting construction in lane for gob side entry retaining, described supporting construction includes frame and many anchor poles, described
Frame includes back timber and canopy lower limb；
Described many anchor poles interval is located at the top in tunnel, so that tunnel is carried out suspension roof support；
Being connected with described anchor pole one end of described back timber, the other end is located at goaf side sideline so that described back timber
Support the top board in described tunnel；
Described canopy lower limb one end is installed in the base plate in tunnel, by the other end of described canopy lower limb with described back timber near goaf
End connect.
Owing to using technique scheme, the method have the advantages that
1, the supporting construction and the method for protecting support thereof that protect lane for gob side entry retaining that the present invention provides, it uses single lower limb to carry out propping up
Protect, compared to traditional full frame support technology, significantly simplify the support process of gob side entry retaining, alleviate workman and work by force
Degree；The material used due to this supporting construction reduces, and therefore, reduces gob-side entry retaining support cost, propping up of this supporting construction
Protect cost about to build by laying bricks or stones or placing concrete protects the 15% of lane supporting, be the 70% of full beam canopy frame support structure cost；Due to top
Beam is connected with anchor pole, and therefore both interactions make the stability of this supporting construction more higher than full beam canopy frame support structure；
Account for simultaneously this supporting construction 80% frame part the most recyclable.
