The Approach Of Pipe Jacking Artificially Of Heavy-Calibre Drainage Pipeline In The Gobi Desert

Carry and is in charge of constructing and beginning to use and popularize and begin gradually in recent years in Xinjiang, had not been similar to the construction experience of the project more or less in the urban construction of Xinjiang in the past, it is peculiar Gobi desert and soil to combine with a lot of soil property in the area of Xinjiang (one kind of the similar gravel soil ), cause in soil property this constructing with various kinds of materials construction method and model different to some extent mathematics that record under the terms. Through carrying the research in charge of the construction method to the river shoal way heavy-calibre drainage pipeline of Urumchi , will help the popularization and use of this kind of project in similar soil property and environment. This literary grace uses two kinds of research approaches of quantitative analysis and qualitative analysis, is carried and in charge of carrying on detailed research in construction method the heavy-calibre drainage pipeline under the soil condition of Gobi desert . Method to adopt quantitative analysis, in normal Gobi desert in constructing to carry strength and have to carry process of entering , cover a great deal of factor , thickness of soil and person who lean towards of axial is it analyse and research to go on close relation with it soil; Method to adopt qualitative analysis, in soil property loose, cave in, under the heavy geological condition roof fall and underground person who wells up water, strengthen and deal with the note thick liquid to the bad ground first , and then carry the discussion of the construction method that is in charge of constructing and study. According to the result studied about the actual project , summarize it under tunnelling and carrying and managing the construction method artificially , routine Gobi desert is it is it construct of mathematics model of strength to in charge of to carry about 1800mm armored concrete drainage pipeline at the soil, result of study show because original state Gobi desert soil become person who join to be strong , only with is it enter process have close relations to carry the strength, with having too great dependence to cover such influence factors as the thickness of soil , deviation ,etc.; Meanwhile, strengthen to bad foundation descendant worker tunnel research in charge ofed to carry indicate, little pipe note thick liquid strengthen foundation treated ground foundation, reach and even exceed bearing the weight of strength and becoming competence of joining of similar soil property basically, for in soil property loose, cave in, roof fall andunderground person who wells up water heavy location is it is it is it is it summarize one effectual method to construct to in charge of to carry to go on. Therefore the research results of this text, to carrying and managing the popularization and use in Xinjiang of construction technology, have important realistic meanings in carrying on the research similar to the project more in the area of Xinjiang.
