Abstract
The utility model provides a pair of interim supporting construction in soft rock tunnel in mine, including polylith backplate and many stocks, backplate is the arc sheet metal or levels the sheet metal and cover on soft rock tunnel lateral wall in mine or top arch, stock one end spiro union has lock nut, the stock other end passes at least one backplate and stretches into in the soft rock tunnel in mine afterwards and through closing soon lock nut makes the backplate centre gripping is in between lock nut and the soft rock tunnel in mine. Adopt the technical scheme of the utility model, utilize less structure to accomplish temporary support at the excavation site, supporting construction is simple, and easily dismouting relates to the structure less, and the supporting time is short, and each structure can reuse, and it is convenient to shift or transport, has improved utilization of resources efficiency to be applicable to the mine soft rock tunnel that has various irregular shape cross sections, the assembly is nimble, and the range of application is wide.
Description
Technical Field
The utility model belongs to the technical field of mine ventilation equipment, especially, relate to a mine soft rock tunnel temporary support structure.
Background
The natural characteristics of soft rock can be summarized to be weak, loose, expansion, weathering, high ground stress and the like basically, the surrounding rock stress begins to change along with the excavation of a roadway, obvious plastic deformation is generated, the problem of deep well ground pressure is a great technical problem after mine exploitation reaches a certain depth, when the exploitation depth reaches a certain depth, the concentrated stress at the periphery of the roadway exceeds the strength of the surrounding rock of the roadway, various forms of damage can be generated at the periphery of the roadway, the ore pressure is more severely displayed, the difference is larger compared with that of a shallow rock stratum, and the similar soft rock problem can also occur at the deep part of the mine even in a rock stratum with higher strength of a rock body, namely the surrounding rock pressure is large, and the roadway is difficult to support. The existing soft rock roadway supporting structure generally adopts single supports such as anchor, net and spray support, and the supporting structure has the disadvantages of more related structural members, complex installation, long supporting time, difficult reuse and inconvenient transfer or carrying.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a mine soft rock tunnel temporary support structure.
The utility model discloses a following technical scheme can realize.
The utility model provides a temporary supporting structure of a mine soft rock roadway; including polylith backplate and many stock, the backplate is the arc sheet or levels the sheet metal and cover on soft rock tunnel lateral wall of mine or the arch of top, stock one end spiro union has lock nut, the stock other end passes at least one backplate and stretches into in the soft rock tunnel of mine afterwards and through closing soon lock nut makes the backplate centre gripping is in between lock nut and the soft rock tunnel of mine.
And a gasket is clamped between the locking nut and the supporting plate.
The outer diameter of the gasket is larger than that of the locking nut.
The locking nut is a hexagon nut.
Two adjacent supporting plates are fixedly connected together by using bolts in an overlapped mode, all the supporting plates are sequentially connected in an overlapped mode to form a protecting plate assembly, and the cross section shape of the protecting plate assembly is consistent with the cross section shape of a soft rock roadway of the mine.
The number of the anchor rods is more than 4 times of that of the support guard plates.
The supporting and protecting plate is made of metal.
The anchor rod is made of resin.
The beneficial effects of the utility model reside in that: adopt the technical scheme of the utility model, utilize less structure to accomplish temporary support at the excavation site, supporting construction is simple, and easily dismouting relates to the structure less, and the supporting time is short, and each structure can reuse, and it is convenient to shift or transport, has improved utilization of resources efficiency to be applicable to the mine soft rock tunnel that has various irregular shape cross sections, the assembly is nimble, and the range of application is wide.
Drawings
Fig. 1 is a front view of the present invention;
fig. 2 is a cross-sectional view of the present invention.
In the figure: 1-supporting guard plate, 2-anchor rod, 3-locking nut, 4-mine soft rock roadway and 5-gasket.
Detailed Description
The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.
As shown in fig. 1 and fig. 2, the utility model provides a mine soft rock tunnel temporary support structure, including polylith backplate 1 and many stock 2, the backplate 1 is the arc sheet metal or levels the sheet metal and cover on mine soft rock tunnel 4 lateral wall or crown arch, and 2 one end spiro unions of stock have lock nut 3, and 2 other ends of stock pass at least one backplate 1 stretch into behind the mine soft rock tunnel 4 and make 1 centre gripping of backplate between lock nut 3 and mine soft rock tunnel 4 through closing lock nut 3 soon.
Furthermore, a gasket 5 is clamped between the locking nut 3 and the support plate 1. The outer diameter of the gasket 5 is larger than that of the locking nut 3. The lock nut 3 is a hexagonal nut.
In addition, two adjacent supporting and protecting plates 1 are fixedly connected together by using bolts in an overlapped mode, all the supporting and protecting plates 1 are sequentially connected in an overlapped mode to form a protecting plate assembly, and the cross section shape of the protecting plate assembly is consistent with the cross section shape of the soft rock roadway 4 of the mine. The number of anchor rods 2 is preferably 4 times or more the number of the supporting plates 1. The material of the supporting and protecting plate 1 is metal. The material of the anchor 2 is resin.
Adopt the technical scheme of the utility model, utilize less structure to accomplish temporary support at the excavation site, supporting construction is simple, and easily dismouting relates to the structure less, and the supporting time is short, and each structure can reuse, and it is convenient to shift or transport, has improved utilization of resources efficiency to be applicable to the mine soft rock tunnel that has various irregular shape cross sections, the assembly is nimble, and the range of application is wide.
