Grouting And Plugging Technology Research On The Application Of Water Engineering In Coal Mine Roadway

The development of the society more and more fast, this is dependent on the construction industry for the development of the society. This decades in our country civil industry got the unprecedented development, especially in the vertical direction construction, can be very high, can also be very deep. In a well-known, the stability of buildings without foundation, so the technical level of underground engineering also plays an important role in the development of the industry. The domestic researches on the level of underground engineering is still in the groping stage, engineering experience and an engineering example with the international advanced level there is a certain gap. Based on underground engineering field first, study of grouting technology in the field of geotechnical engineering reinforcement.At present, the grouting technology is not mature enough, grouting construction often only depend on engineering experience to carry out without a definite standards and norms, the grouting engineering brings great difficulties, in the construction of many uncertain factors often caused a lot of damage to engineering, and will cause excessive waste because of the above reasons, and can not meet the engineering requirements. Therefore, it is urgent to study the grouting technology, and to improve the safety of the project, and also indirectly promote the development of the social industry.This paper first describes the development of grouting technology at home and abroad of the history and the current situation of research in Xinji No. two mine tunnel water gushing phenomenon as the research background, the tunnel gushing analyzed the reasons of the research, and application of grouting technology for a series of analysis and research.Secondly, combined with grouting project, the grouting effect analysis, put forward the double liquid alternate grouting scheme, and the practical application of plugging the program carries on the theoretical analysis, provide theoretical basis for the research. Double liquid alternative grouting, as the name suggests, is to inject a large number of cement slurry, and then flush the pipe, then injected into the water glass solution of an alternative way of construction.Finally, to the practical application of the double liquid alternative grouting in engineering to carry on the research analysis, can draw the factors affecting grouting effect which, emerged from the root of a series of studies are discussed, mainly for the cause of the problem analysis, and puts forward the corresponding solutions, and provides a theoretical basis for the development and application of grouting technique.
