Technical field
The utility model belongs to underground coal mine support technology field, and in particular to a kind of bottom arch supporting of baseboard of coal mine roadway
Structure.
Background technology
It is that colliery, metal mine, subway, civil air defense constructions and installations and underground space engineering etc. are frequent that the bottom plate of tunnel or chamber, which is heaved,
The problem of running into.Especially coal mining when by mining pressure or pick lane when influenceed by secondary supercoated stress, tunnel or chamber
Surrounding convergent deformation is serious, and the amount of heaving of bottom plate reaches more than half of roof to floor convergence, and even up to 90%.Tunnel or cave
Every 2~3 months quantities with regard to needing to reprocess the quantities once, reprocessed or even exceed new pick tunnel in room.Excessive pucking amount
The useful area of tunnel or chamber is severely impacted, it is normally raw to threaten ventilation safety, drawing-off gas, transport of materials of mine etc.
Production system and related link, and be all severely impacted using the stability of roadway's sides and top plate after acting as a planted agent repeatedly, in horse
Head door nearby even the serious threat borehole wall stabilization, cause the borehole wall to slide.
In order to prevent pucking phenomenon, strengthen the supporting to bottom arch and be particularly important, the most frequently used method is to adopt in colliery
With totally enclosed shed shoring.But shed ding support belongs to passive protecting, support does not have initial Support Resistance after setting up, can only lean on bottom
Deformation when small drum for marking time rises provides reaction for it, if subjected to the influence of unbalance loading load, shed is difficult to play effective control bottom work
With.Substantial amounts of engineering practice shows that this set support system effectively plays a role when being difficult to long, and new pucking still will be by reprocessing
Solve.Except planted agent when reprocessing, it is necessary to set up again after the shed of erection is all removed, the input of this quantities is very
It is huge, and work efficiency is extremely low.
Utility model content
The purpose of this utility model is to overcome existing bottom arch guard technology existence and stability poor, and tunnel, which is pressurized easily, to be occurred instead
Multiple pucking is, it is necessary to which roadway floor carries out regular the problem of handling repeatedly.
Therefore, the utility model provides a kind of bottom arch supporting construction of baseboard of coal mine roadway, including it is arranged on the arch of bottom
Multiple anchor poles, in addition to be covered in the upper bar-mat reinforcement of bottom arch inner concave, be provided with above the bar-mat reinforcement for fixing steel
The steel band beam of muscle net, the steel band beam are the arc-shaped to be matched with bottom arch concave surface；Perforation, institute are evenly arranged with the steel band beam
Anchor pole is stated to insert in the arch of bottom through perforation.
Iron pallet is provided between the steel band beam and the anchor pole.
The steel band beam is provided with multiple rows of, and I-shaped cable wire rope beam is vertically installed with steel band beam.
Anchor cable is provided with the I-shaped cable wire rope beam.
The I-shaped cable wire rope beam length 1.2m.
A diameter of 16mm of the anchor cable, length 7.3m.
The size of the iron pallet is 120mm × 120mm.
The length of the steel band beam × a width of 5.1m × 13mm.
The beneficial effects of the utility model：The bottom arch supporting construction of this baseboard of coal mine roadway provided by the utility model,
It is not only simple in structure, and the stability of bottom arch can be provided, reduces the situation for pucking occur, and improve bottom plate pressure resistance
Degree, enhance the stability of bottom plate.
The utility model is described in further details below with reference to accompanying drawing.

Embodiment
For the technological means and effect that the utility model is reached predetermined purpose and taken is expanded on further, below in conjunction with accompanying drawing
And embodiment describes in detail as follows to specific embodiment of the present utility model, architectural feature and its effect.
In order to overcome existing bottom arch guard technology existence and stability poor, tunnel, which is pressurized easily, there is repeatedly pucking, it is necessary to lane
Road bottom plate is carried out regular the problem of handling repeatedly, and the utility model provides a kind of described coal mine roadway bottom as shown in Figure 1, Figure 2
The bottom arch supporting construction of plate, including the multiple anchor poles 3 being arranged on the arch of bottom, anchor pole 3 is mainly used in piercing in the arch of bottom, such as Fig. 3 institutes
Show, bottom can be encircleed to all directions and be fixed with rock, play a part of preventing pucking phenomenon to a certain extent, but this
The appearance of phenomenon can not be entirely prevented underestimating, in order to preferably prevent the appearance of pucking phenomenon, the bottom of the baseboard of coal mine roadway
Arch supporting construction also includes the upper bar-mat reinforcement 1 for being covered in bottom arch inner concave, and the top of bar-mat reinforcement 1 is provided with for fixed steel bars net
1 steel band beam 2, the steel band beam 2 are the arc-shaped to be matched with bottom arch concave surface；Perforation, anchor pole 3 are evenly arranged with steel band beam 2
Through in the arch of perforation insertion bottom.Bar-mat reinforcement 1 covers bottom arch surface, from steel band beam 2 with being fixed with anchor pole 3, in order to increase
