【摘要】：以LXB工程水源工程TBM施工段為典型案例,結(jié)合工程特點(diǎn)設(shè)計(jì)并使用TBM同步仰拱襯砌臺(tái)車,以加快TBM運(yùn)行中仰拱混凝土的施工。在已有技術(shù)的基礎(chǔ)上進(jìn)行了優(yōu)化創(chuàng)新,臺(tái)車斷面采用非對(duì)稱布置形式,避讓連續(xù)皮帶機(jī);臺(tái)車設(shè)置6個(gè)16 m長的工作區(qū),合理布置清渣、鋼筋綁扎、止水安裝、模板安裝、澆筑、養(yǎng)護(hù)等工序;充分考慮臺(tái)車內(nèi)雙線通行以及車載混凝土攪拌罐的穿行,設(shè)計(jì)使用升降坡軌道連接裝置,實(shí)現(xiàn)與TBM正常軌道的搭接過渡。工程實(shí)踐表明,在保證不影響TBM施工的情況下,單臺(tái)車月均可完成仰拱襯砌546 m,既能達(dá)到與TBM掘進(jìn)同步施工的效果,又能達(dá)到縮短工期的目的。該設(shè)計(jì)在地下隧洞施工中具有廣闊的推廣前景。
[Abstract]:Taking the TBM construction section of LXB project as a typical case, combined with the characteristics of the project, the TBM synchronous invert lining car is designed and used. In order to speed up the construction of invert concrete in the operation of TBM, the optimization and innovation are carried out on the basis of the existing technology. The cross-section of the trolley adopts the form of asymmetric arrangement to avoid the continuous belt conveyor. Six 16m long working areas are set up on the bench, with reasonable arrangement of slag cleaning, steel bar binding, water stop installation, formwork installation, pouring, maintenance and so on. Fully considering the double-line passage in the trolley and the crossing of the in-vehicle concrete mixing tank, this paper designs and uses the lifting slope track connection device to realize the lap transition with the normal track of TBM. The engineering practice shows that. Under the condition that the TBM construction is not affected, the inverted arch lining can be completed by a single vehicle or month, which can achieve the effect of synchronizing construction with TBM tunneling. The design has broad prospect in underground tunnel construction.
