井巷工程格栅拱架支护定额基价的探讨

Discussion on Fixed Base Price of Grid-steel Support in Roadway Engineering

通过对格栅拱架地面制作加工及井下安装施工分析,得出格栅拱架制作架设的主要工作内容。在分析金属支架支护定额与金属支架制作定额组价构成的基础上,对井巷格栅拱架补充定额基价进行了详细探讨。根据同等工作量成正比原则,对比参照钢筋制作绑扎和金属网制作铺设2个标准定额,得出井巷格栅拱架补充定额B001参照定额基价为4 550元/t,从而为格栅拱架支护的井巷工程投资概预(结)算工作提供合理计价依据。

By analyzing ground production and processing and underground fixing of the grid - steel, the main tasks of the fabrication and fixing of grid - steel are achieved. On the basis of analyzing the supporting quota and production quota price constitution of metal support, the additional fixed base price of roadway grid - steel is discussed in detail. According to the principle that same workload is proportional. Comparing the two standard quotas between assembiling reinforcement and metal - net production, it achieves that the the reference fixed base price of roadway additional quota B001 is 4 550 Yuan/t, thus, it provides a reasonable valuation basis for invest-ment estimate budget （ node ） of the grid - steel support in roadway engineering.
