Abstract
The utility model discloses a stay lane floodwater drainage side pillar seam formula stock, including the steel pipe, the steel pipe is the round platform form, and it has the pipe seam vertically to open along it on the steel pipe, and the main aspects rigid coupling of steel pipe has the hoop, lies in on the steel pipe just to have cup jointed the layer board near hoop department between the tip of hoop and steel pipe. The utility model discloses simple structure, convenient to use are through welding a hoop at a root zone tapering and on opening the steel pipe that has the pipe seam to cup joint a square layer board, the elasticity of utilizing the steel pipe when country rock production displacement, produces frictional resistance to pore wall radial pressure between this stock and pore wall, and the layer board forms pressure to rock -wall, makes the country rock be in three -directional stress state, reaches reinforced surrounding rock, prevents the purpose of country rock removal. And along with the working face back production, the waste rock is the compaction gradually, and the stock will play floodwater drainage and protect group's effect.
Description
Technical field
The utility model belongs to protector technical field, and in particular to one kind stays lane Dang Gan sides to protect pipe-seam type anchor rod.
Background technology
During S1201 working face extractions, glue fortune crossheading applies " 110 engineering method " i.e. high seam without coal pillar mining technology, and " 110
Engineering method " refers to a tunnel, working face, a zero coal column construction method.Compared with traditional " 121 engineering method ", " 110 engineering method "
A gate road need to be tunneled, another tunnel is changed into continuous exploitation by cutting top release automatic lane forming, working face from " jump is adopted ",
And can realize that Y shape is divulged information, and tunnel periodic pressure is effectively reduced, safety, economic benefit are very prominent, are described as by industry
" third time mining industry technological change ".When implementing " 110 engineering method ", crossheading cuts the gear cash supporting of top side construction using U-shaped bracket support,
As spoil constantly inbreak in goaf is compacted, the U-shaped support in gear cash side bears whole country rock radial stresses, and caved gangue is outside
Portion's lane space is constantly moved, and is directly influenced the supporting quality of the U-shaped support in gear cash side and is stayed Xiang Duancheng lanes effect.
Utility model content
The purpose of this utility model is to provide one kind and stays lane Dang Gan sides to protect pipe-seam type anchor rod, solves gear cash side caved gangue and moves
Adverse effect of the dynamic deformation to Liu Xiangduancheng lanes effect.
The technical scheme that the utility model is adopted is：One kind stays lane Dang Gan sides to protect pipe-seam type anchor rod, including steel pipe, steel pipe
For round table-like, pipe seam is provided with along its longitudinal direction on steel pipe, the big end of steel pipe is connected with iron hoop, iron hoop is located on steel pipe little with steel pipe
Supporting plate is socketed between end and at iron hoop.
The characteristics of the utility model, also resides in：
Supporting plate is square.
The beneficial effects of the utility model are：One kind of the present utility model stays lane Dang Gan sides to protect pipe-seam type anchor rod, structure letter
It is single, easy to use, by with taper and being provided with the steel pipe of pipe seam one iron hoop of welding at one, and it is socketed a square support
Plate, radial pressure is produced using the elasticity of steel pipe to hole wall, when country rock produces displacement, friction resistance is produced between the anchor pole and hole wall
Power, supporting plate forms pressure to crag, makes country rock in triaxial stress state, reaches reinforcing country rock, prevents the purpose of Surrounding Rock Movement.
And with working face extraction, spoil is gradually compacted, anchor pole will play the wall supporting effect of gear cash.
Description of the drawings
Fig. 1 is a kind of main structure diagram for staying lane Dang Gan sides to protect pipe-seam type anchor rod of the utility model；
Fig. 2 is a kind of side view cutaway drawing for staying lane Dang Gan sides to protect pipe-seam type anchor rod of the utility model；
Fig. 3 is a kind of arrangement figure for staying lane Dang Gan sides to protect pipe-seam type anchor rod of the utility model.
In figure, 1. steel pipe, 2. pipe seam, 3. supporting plate, 4. iron hoop.
Specific embodiment
Below in conjunction with the accompanying drawings the utility model is described in further detail with specific embodiment：
One kind of the present utility model stays lane Dang Gan sides to protect pipe-seam type anchor rod, as shown in Figure 1 and Figure 2, including steel pipe 1, steel pipe 1
For round table-like, pipe seam 2 is provided with along its longitudinal direction on steel pipe 1, the big end of steel pipe 1 is connected with iron hoop 4, iron hoop 4 and steel are located on steel pipe 1
Supporting plate 3 is socketed between the small end of pipe 1 and at iron hoop 4, supporting plate 3 is square.
Appropriate location jump bit is found in work progress to pound into lane side, and the anchor pole press-in is less than into its external diameter using external force
Drilling in, the elasticity of steel pipe 1 produces radial pressure to hole wall, when country rock produces displacement, produces between the anchor pole and hole wall and rubs
Resistance is wiped, the supporting plate 3 of anchor pole forms pressure to crag, makes country rock in triaxial stress state, reaches reinforcing country rock, prevents country rock
Mobile purpose.And with working face extraction, spoil is gradually compacted, anchor pole will play the wall supporting effect of gear cash.
Onsite application situation：
The pipe-seam type anchor rod site layout project is as shown in figure 3, pipe-seam type anchor rod is arranged in cuts after fend off cash supporting side, waste rock board
Face, horizontal direction is arranged in the centre position of the two you headstocks, about away from termination frame 600mm, vertical direction two rows of arrangement, and first
Array pitch base plate 1m, second row is away from base plate 2.5m.
The pipe-seam type anchor rod totally four kinds of models：
