Reticulated shell member flat plate type net sales of flat shell member reticulated shell member reticulated shell member characteristic feature flat plate type latticed shell member PRODUCTS soft rock roadway has been a key technical problems affecting the production and construction of the further development of the coal industry One. Deep mine to high pressure in mining influence and impact ground pressure conditions, ground control is particularly difficult, and therefore more and more to strengthen support systems, such as 29U steel support frame away from the need to reduce, enhance contact rod, or even to use the U36 steel ; Anchor Mesh to use steel arch support reinforcement, or the anchor, grouting surrounding rock joint support; although such support can achieve a certain effect, but the high cost of support. Therefore, Coal create a new plate-type network shell member, the main feature of this tablet support reticulated shell member summarized as follows: "While Excavation and support, while support side let, just, adequate stiffness after the first soft, step simple, inexpensive. " zmjt15 flat type housing member supporting roadway network features 1, "While Excavation support" timely support. After the flat reticulated shell member backfilling available waste rock, ash bag, filled with precast concrete panels that contour grid and tunnel quickly snug, while excavation and support, timely support, so that one can stand to support resistance in time to play, to make timely reinforcement of surrounding rock and work in the three-dimensional stress; on the other hand played a slow pressure equalizing the role of the carriage along the roadway surrounding the force tends to be uniform and in good working condition. 2, flat reticulated shell member having sufficient "rigidity." 3, "Sophie let moderate" and "after the first soft Gang." Force plate reticulated shell member having more complex components: expansion of rock, creep, long time strength decreases, broken rock fall bond coefficient values, etc., which all showed macroscopic displacement of rock mass, any rigid stent want to completely prevent displacement itself will be set at a disadvantage. Therefore, a stable roadway will ultimately be accomplished through joint action bracket, rock. Network shell support to withstand greater stress in the same time, the reaction in the surrounding rock, so that the surrounding rock convergence is a convergent support under control, side by side branch stent allow, continue to converge broken rock compaction, to form a stable load ring, and stand together to assume the role of stress. ? Flat reticulated shell member retractable from two aspects: (1) stand in contact with the surrounding rock reinforcement grid itself has a certain reducible; (2) the connection between the network shell support film and the film?? wooden plate at. Application of flat reticulated shell member engineering (1) using conventional metal stents or reinforced concrete arch sprayed layer as reinforcing ribs, shotcrete internally generated great moment, the need to focus on strengthening; semi-rigid bar shell not only improve the spray layer bearing capacity, but also eliminates the spray layer bending internal forces. (2) flat reticulated shell member change from passive support to active support, while having a large support resistance and has good shrink, while the stent structure "after the first soft on" feature, in line with the soft rock The basic idea of ??retaining the support. (3) through the field of reinforced strain, roadways and surrounding rock displacement measuring convergence can be good overall HowNet shell bolting and shotcrete lining structure and surrounding interaction, it is possible to extend the rock steady since time is conducive to full its role surrounding rock. (4) the use of plate-type network shell member showed that the new technology construction safety, technology is feasible, so a successful support, has changed some of roadway requires constant maintenance or repair of the situation fundamentally. (5) The successful application of flat reticulated shell member of Soft Rock Support provide a successful experience. According to technical analysis, that the new support structure design, strong integrity, with the ability to resist deformation of roadway large compared with the heavy steel U bracket, you can save steel 40%, reduce direct costs by about 30% bracket, which can be in high stress soft rock roadway support to promote and applications. The product has been exported to many countries, the United States, France, Canada, Indonesia, Russia, Vietnam, Australia, South Korea, Iran, etc., unanimous praise.
