By crossbeam limit on anchor cable, while crossbeam being hung using crossheading top wire rope；Coal wall is protruded at crossbeam both ends, in crossbeam
Top filling filler tamps.
Preferably, every crossbeam is at least fixed with two anchor cable ends.
Preferably, the filler of filling are as follows: move towards to strip off the skin using old anchor pole, the cooperation of basketry piece and expect place mat on crossbeam along crossheading
Portion, and be fixed on crossbeam with iron wire or wirerope；Expect that top fill tightly using coal (cash) bag cooperation sleeper stripping off the skin.
Preferably, adjacent two anchor cable spacing are 1.5m in every row, move towards adjacent two crossbeams spacing 1.5m along crossheading, strip off the skin
Expect that the spacing along crossheading width direction is 1m.
Preferably, the crossbeam protrudes into 300~500mm of coal wall.
Preferably, the crossbeam is made of more I-steel head and the tail overlap joint, lap-joint's at least anchor cable also cross.
The present invention also provides a kind of crossheading big cross section freeboard sections to connect top, including sets along crossheading middle line and middle line two sides multiple rows of
Anchor cable, two sides anchor cable is identical at a distance from middle line and portion of side, and is fixed on the crossbeam of anchor cable end, and crossbeam is along crossheading width side
To setting, one end of the beam protrudes into coal wall, and filler is inserted above crossbeam and is tamped.
Preferably, eyelet is offered on the crossbeam, anchor cable end passes through the eyelet on crossbeam, and with fixing piece by crossbeam
Limit is hung crossbeam on anchor cable, while using crossheading top wire rope.
Preferably, the fixing piece is rope card.
The present invention has the advantages that
Crossbeam is fixed by wirerope, fixing piece, makes to connect top more more stable and stronger, improves back production to this section
Safety coefficient provides guarantee for the normal back production of working face.Waste and old anchor pole and the material etc. that strips off the skin are filled on crossbeam, play waste
Required intensity can be reached while utilization.
Detailed description of the invention
Fig. 1 connects the overall structure diagram after top method connects top using crossheading big cross section freeboard section for the present embodiment.
Specific embodiment
The effect of to make to structure feature of the invention and being reached, has a better understanding and awareness, to preferable
Examples and drawings cooperation detailed description, is described as follows:
As described in Figure 1, a kind of crossheading big cross section freeboard section connects top method, comprising the following steps:
First 3 row's anchor cables 1, identical, the anchor at a distance from middle line and portion of side of two sides anchor cable 1 are set along crossheading middle line and middle line two sides
1 protruded length of rope is set according to crossheading height.By the I-steel 2 with eyelet along crossheading width direction across multiple rows of anchor cable 1, anchor
1 end of rope passes through the eyelet on I-steel 2, and is limited I-steel 2 on anchor cable 1 with rope card 3, while using steel at the top of crossheading
Cord 4 hangs I-steel 2；Every I-steel 2 is at least fixed with two 1 ends of anchor cable.I-steel 2 in two sides coal wall is equal
The depth that one end puts in coal wall 10 is 300~500mm, and one end is docked with another I-steel 2, and docking length is wide according to crossheading
Degree, the setting of 2 length of I-steel, the position of docking will guarantee have an anchor cable 1 also cross two I-steel 2.
It moves towards to strip off the skin 7 place mats of material on 2 top of I-steel using old anchor pole 5, the cooperation of basketry piece 6 along crossheading, and with iron wire or steel
Cord 4 is fixed on I-steel 2；Sleeper 9 is cooperated fill tightly using coal (cash) bag 8 stripping off the skin 7 tops of material.
1 spacing of adjacent two anchor cables is 1.5m in every row, moves towards adjacent two I-steel, 2 spacing 1.5m along crossheading, strip off the skin material 5
Spacing along crossheading width direction is 1m.
A kind of crossheading big cross section freeboard section connects top, including sets multiple rows of anchor cable, two side anchors along crossheading middle line and middle line two sides
Rope is identical at a distance from middle line and portion of side, and is fixed on the crossbeam of anchor cable end, and crossbeam is arranged along crossheading width direction, crossbeam
Coal wall is protruded into one end, and filler is inserted above crossbeam and is tamped.Crossbeam is made of more I-steel head and the tail overlap joints, is opened up on I-steel
There is eyelet, anchor cable end passes through the eyelet on I-steel, and is limited crossbeam on anchor cable with rope card, while using at the top of crossheading
Wirerope hangs crossbeam.It moves towards to strip off the skin 7 place mats of material on 2 top of I-steel using old anchor pole 5, the cooperation of basketry piece 6 along crossheading, be used in combination
