Abstract
A plate chain type roadway stop wall is structurally composed of wallboards and chains. Each wallboard is in the shape of L and provided with an upper folded edge and a lower folded edge. Joints of every two adjacent wallboards can be inserted into each other. One chain is arranged between the inner sides of every two adjacent wallboards. The upper end of each chain is connected with the upper sides of the corresponding wallboards. Holes are formed in the inner sides of the lower folded edges, holes are perpendicularly drilled into the ground in the positions of the holes, expansion hooks are inserted in the drill holes and fastened, the chains are hung in the expansion hooks and tensioned, and thus the intensity of stress on the side faces of the wallboards is increased.
Description
Technical field
A plate chain type tunnel stock retaining wall, belongs to mining equiment field.
Background technology
In the tunnel of down-hole, often to store the bulk cargo that some shotcretes are used, in order to make the bulk cargo side of occupation of land and prevent from shedding waste less, a side in tunnel has been built stock retaining wall by laying bricks or stones, but not only own vol is large for this backgauge body of wall of building by laying bricks or stones, can't integrated moving and Reusability, be not suitable with the needs of bulk cargo transition.
Summary of the invention
The application's object is that a kind of plate chain type tunnel stock retaining wall will be provided, and it can be removed easily, installation and Reusability.Structure is connected to form by wallboard and chain.Wallboard is made of the steel plate of a rectangular 2-3 millimeter thickness, the wallboard of making after moulding is L (side) type, horizontal both sides (two of long limit, L-type) at wallboard are provided with upper and lower flanging, wherein upper hem outwards reverses and is ∩ type, lower hem inwardly reversion is rectangular in shape, and with this, increases the structural strength of wallboard.Wallboard height after flanging is less than the height of mine car, so that decking.The following width of wallboard after flanging is less than height, with conservation and weight reduction.The size of two blocks of adjacent wallboards not etc., can mutually not insert by the joint of two blocks of adjacent wallboards, so that combination is installed.
Between the inner side, edge of the upper and lower flanging of wallboard, be provided with some chains, the chain at wallboard two ends is apart from 10 centimetres of the terminations of wallboard, so that the grafting of wallboard is connected; The upper end of chain and the upper hem of wallboard inner side are fixedly linked and are integral.On the side lining of lower hem, be provided with several holes (row's hole), the position of hole and chain is corresponding, and hole is used for installing wallboard to be used.
When wallboard is installed, the lower hem of wallboard faces toward the wall in tunnel, and parallel with the wall in tunnel, and the two ends of some blocks of wallboards are plugged and are integral, and wallboard, from the distance of the wall in tunnel, determines the storing capacity of wallboard.Hole place vertical drilling below wallboard, in boring, insert expansion hook fastening, the rock three on hook and wallboard, ground of making to expand is connected as a body, chain is hung in expansion hook, chain is just in time strained, chain after tension and the both sides of wallboard form triangle, thus increased wallboard side be subject to force intensity; During entrucking, run into chain and be in the way, chain can be removed from expansion hook, chain is foundered to the sidewall outer of wallboard, in order to avoid affect entrucking.Not the used time, the expansion hook of wallboard is laid down, wallboard is oppositely placed on to a jiao of tunnel wall, save very much the space in tunnel.
Facts have proved, plate chain type tunnel stock retaining wall is highly suitable for storing in the tunnel of down-hole, transition is used, thereby saved a large amount of masonry panels.

The specific embodiment
As shown in Figure 1, 2, a kind of plate chain type tunnel stock retaining wall, it can be removed easily, installation and Reusability.Structure is connected to form by wallboard 1 and chain 2.The steel plate of a rectangular 2-3 millimeter thickness of wallboard 1 use is made, the wallboard 1 of making after moulding is L-type (side), horizontal both sides (two of long limit, L-type) at wallboard 1 are provided with upper and lower flanging 3,4, wherein upper hem 3 outwards reverses and is ∩ type, lower hem 4 inwardly reversion is rectangular in shape, and with this, increases the structural strength of wallboard 1.The height of the wallboard 1 after flanging is less than the height of mine car, so that decking.The following width of the wallboard 1 after flanging is less than height, with conservation and weight reduction.The size of two blocks of adjacent wallboards 1 not etc., can mutually not insert by the joint of two blocks of adjacent wallboards 1, so that combination is installed.
Between the inner side, edge of the upper and lower flanging 3,4 of wallboard 1, be provided with some chains 2, the chain 2 at wallboard 1 two ends is apart from 10 centimetres of the terminations of wallboard 1, so that the grafting of wallboard 1 is connected; The inner side of the upper hem 3 of the upper end of chain 2 and wallboard 1 is fixedly linked and is integral.On the side lining 1 of lower hem 4, be provided with several holes 5 (row's hole), hole 5 is corresponding with the position of chain 2, and hole 5 is used for wallboard 1 is installed.
When wallboard 1 is installed, the lower hem 4 of wallboard 1 faces toward the wall 7 in tunnel, and parallel with the wall 7 in tunnel, and the two ends of some blocks of wallboards 1 are plugged and are integral, and wallboard 1, from the distance of the wall 7 in tunnel, determines the storing capacity of wallboard 1.Hole 5 place's vertical drillings below wallboard 1, in boring, insert expansion hook 6 fastening, the rock three on hook 6 and wallboard 1, ground of making to expand is connected as a body, chain 2 is hung in expansion hook 6, chain 2 is just in time strained, chain 2 after tension and the both sides of wallboard 1 form triangle, thus increased wallboard 1 side be subject to force intensity; During entrucking, run into chain 2 and be in the way, chain 2 can be removed from expansion hook 6, chain 2 is foundered to the sidewall outer of wallboard 1, in order to avoid affect entrucking.Not the used time, the expansion hook 6 of wallboard 1 is laid down, wallboard 1 is oppositely placed on to a jiao of tunnel wall 7, save very much the space in tunnel.
Facts have proved, plate chain type tunnel stock retaining wall is highly suitable for storing in the tunnel of down-hole, transition is used, thereby saved a large amount of masonry panels.
