Description
Technical field
The present invention relates to a kind of single-track railway tunnel Drillhole excavation chassis, be specifically related to a kind of can the boring excavation chassis of simultaneous adaptation single-track railway tunnel full section method and benching tunnelling method excavation construction。
Background technology
Single-track railway tunnel II, III country rock adopts full face tunneling method construction, and IV, V country rock adopts bench cut method construction, and the height of the boring excavation chassis that tunnel bench cut method shows with full face tunneling differs relatively big, and tunneling boring chassis to increase an operation layer。Tunnel surrounding is ever-changing, various grade country rocks often interlaced together, country rock bypass the immediate leadership change situation be also frequent appearance, excavation method after Change in surrounding rocks is it is possible to can change, particularly country rock bypass the immediate leadership change time often cause full section method and the change of two kinds of excavation methods of benching tunnelling method, and excavation method changes, boring excavation chassis is necessary for changing, owing to tunneling boring boring excavation chassis differs bigger with benching tunnelling method boring excavation chassis height, therefore two kinds of excavation chassis are generally processed during construction, tunneling boring boring excavation chassis is adopted when adopting tunneling boring, more small-sized boring excavation chassis is adopted during benching tunnelling method construction, and single-track tunnel section is less, it is necessary for splash guard laying chassis below and lining trolley to exit outside hole to change boring excavation chassis, when short tunnel, impact is also not as big, and move back a chassis when tunnel is longer and will affect for a long time, strong influence Tunnel Construction Schedule will be had a strong impact on, cause the waste on construction cost。
Summary of the invention
The purpose of the present invention is that and overcomes the deficiency existed in above-mentioned existing construction technology, and a kind of single-track railway tunnel height and all telescopic Drillhole excavation chassis of width are provided, when adopting bench cut method construction, boring excavation chassis can provide the operating platform required for bore operation of topping bar；When full face tunneling method is constructed, extract the bearing pin of locking on chassis column out, with loader, drilling jumbo is raised up to the operating platform height that full face tunneling method construction is required, telescopic outrigger in chassis column puts in place because of deadweight whereabouts, put on locking bearing pin, installing outside bottom drilling operation platform and put down one layer of drilling operation platform inside chassis, chassis can provide the operating platform required for full face tunneling method construction drill operation after flexible converting to；Reverse operating, also can be reduced into bench cut method boring excavation chassis the full fault plane drilling jumbo changed。Expansion link in little operating platform outside drilling jumbo can be protruding according to excavated section simultaneously, can meet the bore operation requirement of widened section。Adopt this Drillhole chassis, can carry out that the tunnel constructed is few processes a boring excavation chassis than common bore operation chassis, and decreasing the impact exchanging boring excavation chassis to lining trolley and two lining constructions, two lining constructions can uninterruptedly continue to be normally carried out。This trolley device, without using professed machine, only uses loader and hand fit to be completed in a relatively short time the mutual conversion to full section method drilling jumbo of the benching tunnelling method drilling jumbo, and construction technology is simple, safe, economic, practical。
The technical scheme is that when single-track railway tunnel adopts bench cut method to construct, telescopic supporting leg is increased in the column of step boring excavation chassis, when interior supporting leg is in contraction state, drilling jumbo can provide the operating platform needed for benching tunnelling method construction drill operation, when interior supporting leg is in and stretches out state, put down one layer of drilling operation platform inside chassis, installing outside bottom drilling operation platform, the boring excavation chassis after flexible conversion meets full face tunneling method construction drill job requirements。Outside drilling jumbo in operating platform expansion link overhanging after, moreover it is possible to meet the bore operation requirement of widened section。
