3、Technical code for shotcrete pock bolts shore
6、The combined bolting and shotcrete in foundation pit is a new technology which includes anchor rod, anchor rope, steel mesh, grid, grouting and shotcrete.
9、Experimental research on single-layer tunnel lining of steel fiber shotcrete
12、Finite element analysis of combined support system of steel arch shelf and lock bolting with shotcrete in diversion tunnel
15、Many site tests have also proved that the strength of anchor and shotcrete support is much greater than that of conventional in situ concrete lining.
18、This paper introduces the test and site-applyi n g of the C40 steel-fibre-shotcrete in the ShanXi WanJiaZhai yellow River Divis ion project Gengeral Main Pump Station1&2.
21、In this paper the design of mix ratio of steel fiber shotcrete and construction method are presented, which can be taken as a reference for the tunnel reinforcement construction.
4、Develpement of simulation system for shotcrete robot virtual prototype
8、Application of shotcrete-bolting technique for slope supporting of deep foundation pit of high rise building
13、The living example show that the technology of deeper fragmenting surrounding rock tunnel repairing by bolting and shotcrete lining is very effective.
17、Most slope greening methods are not suitable for slopes with slope angles larger than 60?, but the slopes reinforced with anchoring bar and shotcrete structures can usually be adopted for slope with a larger slope angle.
1、shotcrete robot operator
7、Performance test of steel fiber shotcrete and design of mixture ratio
14、Due to high in situ stress in the powerhouse area, important deformation of local surrounding rock, rock burst, shotcrete spalling occur during excavation.
20、Technique of spraying the vegetation-growing concrete on the slope protection for slope greening with reinforced shotcrete celluar system is to spray the vegetation-growing concrete on the excavated surface of slope, in order to form a greening slope protection.
10、Research on the key shotcrete technologies for the underground tunnel chambers of Shuibuya Project
19、In this project, shotcrete-bolt and slope are used in most segments of the pit. and pile-anchor is used in some important pit segment this scheme is proved to be successful.
11、Bolt-shotcrete support and small pipe grouting technology used in treating tunnel collapse
5、Nowadays more and more shotcrete liner are applied in tunnel. Whether the shotcrete strength accord design strength will be directly responsible for the timbering reliability.
16、Affected by the backfilling, the tangential stress of shotcrete has a tendency is for pressure stress to be tensile stress; it is dangerous to induce the axial cranny.
2、mesh reinforced shotcrete
