Abstract
The utility model relates to a supporting mesh used for supporting under a coal mine well, in particular to an ultrahigh-strength plastic supporting mesh which comprises the supporting mesh. The supporting mesh comprises longitudinal rib bars and transverse rib bars which are connected, mesh holes are arranged among the longitudinal rib bars and the transverse rib bars, and the shape of each meshhole is a rectangle with circular arc angles. The supporting mesh adopts simple structure; as the design of the connecting area among the mesh holes is strengthened, the tensile strength of the entiresupporting mesh which is formed by continuous stretching is higher than that of a rhombic mesh and a spot welding mesh which are woven by iron wires with the Phi value of 4.0mm (8<#>); therefore, thesupporting mesh can be quickly tensioned in the using process and can exert the function of timely supporting a newly-dug tunnel; moreover, the supporting mesh is flame-retardant and antistatic; as continuous extrusion is carried out on the supporting mesh by a plastic extruding machine, the continuous unidirectional or bidirectional stretching integrity of the supporting mesh is good. Therefore,the supporting mesh is a novel supporting material for digging the two sides of the tunnel under the coal mine well, supporting a top plate and replacing steel by plastics.
Description
Technical field
The utility model relates to the protecting wire net that supporting is used under a kind of coal mine, specifically is that a kind of superhigh intensity plastics prop up protecting wire net.
Background technology
Stope drift active workings group, roof timbering generally adopt wire lath under the coal mine at present, and the metal material waste is serious, and these protecting wire nets exist, and globality is poor, solder joint is stressed or corrosion is easily thrown off, weight is difficult for defectives such as installation greatly.Because nonmetal protecting wire net bulk strength is not high at present, has potential safety hazard especially when doing roof timbering, also there be not nonmetal protecting wire net substitute preferably.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned the deficiencies in the prior art part, provide a kind of colliery to prop up protecting wire net with the superhigh intensity plastics, these superhigh intensity plastics prop up protecting wire net be by the highstrenghtpiston is used modified formula, strengthen between mesh connect area design, the continuously elongated integral body that forms is propped up protecting wire net.The tensile strength of this net surpasses Φ 4.0mm (8
#) the rhombus net and the spot welding net of iron wire braiding, common 8
#The tensile strength of iron wire is 150MPa, and superhigh intensity plastics supporting Netcom crosses and connects area design between the increasing mesh, make vertical, horizontal single tensile strength is all above 300Mpa, uvioresistant, application life 6-10, Heat stability is good, in-10 ℃～+ 70 ℃ temperature ranges, its geometrical stability and mechanics mechanical performance remain unchanged, extensibility 1%, thereby this net can be easy to tensioning promptly, to newly digging the tunnel immediate support good action arranged, and fire-retardant, antistatic, this net is extruded continuously through extruding machine, continuous unidirectional or biaxial tension good integrity, be that down-hole mining tunnel, colliery two is helped, alternative metals net in the roof timbering, particularly roof timbering is to mould the novel support material of Dai Gang.
The utility model is realized with following technical scheme: a kind of superhigh intensity plastics prop up protecting wire net, include a protecting wire net, it is characterized in that: protecting wire net have lengthways of rod and laterally rib is connected, lengthways of rod and horizontal rib be middle a mesh, mesh be shaped as the arc chord angle rectangle.
Described lengthways of rod is that integral plane is connected with horizontal rib.
Described mesh be shaped as arc chord angle rectangle, ellipse or circular.
The utility model has the advantages that: this protective screening is simple in structure, props up protecting wire net owing to strengthen the integral body that connects area design, continuously elongated formation between mesh, and the tensile strength of net surpasses Φ 4.0mm (8
#) the rhombus net and the spot welding net of iron wire braiding, tensioning promptly in the use, to newly digging the tunnel immediate support good action is arranged, and it is fire-retardant, antistatic, this net through extruding machine extrude continuously, continuous unidirectional or biaxial tension good integrity, be that down-hole mining tunnel, colliery two is helped, roof timbering to be to mould the novel support material of Dai Gang.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail:
Accompanying drawing is the utility model structural representation:
Among the figure: 1, lengthways of rod, 2, horizontal rib, 3, mesh, 4, a protecting wire net.
The specific embodiment
As shown in the figure: a kind of superhigh intensity plastics prop up protecting wire net, include protecting wire net 4, a protecting wire net 4 have lengthways of rod 1 and laterally rib 2 is connected, lengthways of rod and horizontal rib be middle a mesh 3, mesh be shaped as the arc chord angle rectangle.
Described lengthways of rod 1 is connected for integral plane with horizontal rib 2.
Described mesh 3 be shaped as the arc chord angle rectangle, oval or circular.
These superhigh intensity plastics prop up protecting wire net be by the highstrenghtpiston is used modified formula, strengthen between mesh connect area design, the continuously elongated integral body that forms is propped up protecting wire net.Tensile strength surpasses Φ 4.0mm (8
#) the rhombus net and the spot welding net of iron wire braiding, common 8
#The tensile strength of iron wire is 150MPa, and superhigh intensity plastics supporting Netcom crosses and connects area design between the increasing mesh, make vertical, horizontal single tensile strength is all above 300Mpa, uvioresistant, application life 6-10, Heat stability is good, in-10 ℃～+ 70 ℃ temperature ranges, its geometrical stability and mechanics mechanical performance remain unchanged, extensibility 1%, thereby this net can be easy to tensioning promptly, to newly digging the tunnel immediate support good action arranged, and fire-retardant, antistatic, this net is extruded continuously through extruding machine, continuous unidirectional or biaxial tension good integrity, be that down-hole mining tunnel, colliery two is helped, alternative metals net in the roof timbering, particularly roof timbering is to mould the novel support material of Dai Gang.
