Description

A kind of lining of railway tunnel two construction working rig
Technical field
The utility model relates to constructing tunnel equipment technical fields.More specifically, the utility model relates to a kind of railways Working rig is used in tunnel double-lining construction.
Background technique
With the raising of China's level of economic development and the increase of high speed railway construction scale, the safe mass and ring of people It protects awareness of saving energy to further enhance, in face of the new situations that human cost is constantly soaring and railway tunnel of growing up largely occurs, railway The demand needs of mechanization of tunnelling level further increase.The Ministry of Railways has issued iron for 2008 and has built letter [ 2008 ] 777 " instruction about railway tunnel construction mechanical arrangements ".Construction party is actively promoting mechanization of tunnelling process, but Construction equipment etc. still lags behind the construction level of same other developed countries of period.Mechanical matching equipment is in hard rock or encloses Just can be carried out quick mechanized construction under the conditions of rock stability is preferable, the mechanical equipment degree domestic on production line compared with It is low, mechanical service life and maintenance are affected, while affecting the efficiency of operation, cannot be formed more complete advanced Machanized line.Especially spray the supporting machinery home-made equipment of the processes such as anchor, supporting and second coagulation soil lining cutting (two linings) Degree is extremely low, constrains the progress and development in an all-round way of the construction of China railways tunnel machineization completely.
Tunnel double-lining is constructed at present, and generally existing mechanization degree is high, mating incomplete situation.The reason is that: (1) it is long China human mortality bonus since phase, superfluous cheap labour market cause owner and construction party to pay attention to mechanized construction inadequate. (2) engineering project feature first is that implement one-time item cannot repeat, projects independent accounts thinks little of long-term plan. (3) the project-basedization management of unit in charge of construction's examination cost, so that the research mechanization investment etc. that project manager is unwilling excessive.
It is that tunnel machine application aspect is dug in tunnel excavation from the case where existing documents and materials and current preliminary examinations Relatively large into upper dynamics, some key equipments such as development machine, drill jumbo, substantially import equipment, domesticize journey Degree is not high, and the particularity of constructing tunnel restricts always the propulsion of mechanization, although each unit in charge of construction was sticking at this in recent years The work of aspect, but in progress relatively slowly, homogeneous situation is commonplace, the mark obtained in terms of tunnel double-lining mechanization Property achievement is also undesirable.
Mechanical equipment used has first branch face cleaning, first branch face to beat anchor pole, geotextile laying, waterproof by process in tunnel double-lining Plate is laid with, reinforcing bar binding is laid, two lining constructions, secondary lining detection finishing, the maintenance of the lining of concrete two, power supply system follow-up laying, wind System supporting maintenance etc. develops some simple targetedly machinery for above-mentioned each process, but this is special narrow in tunnel It is interfered with each other in narrow space greatly, influences to be connected operation between process, intersection work holdup loss is larger, and some equipment are equipped with, because of function Can be single, other operations are influenced, and be forced to leave unused.
In first branch face cleaning, first branch face beat anchor pole, on geotextile laying using it is more be to use scaffold building platform the bottom of at Four castors are installed in portion, manually elapse operation, occupy operation path;Splash guard is laid with, aspect is laid in reinforcing bar binding, using reinforcing bar Splash guard binds rack, and mechanization degree is low;Secondary lining detection finishing, the maintenance of the lining of concrete two, power supply system follow-up laying, wind system Supporting maintenance etc. unite using scaffold foot wheel, also has using scissor Hydraulic aerial cage, in tunnel midline operation Operation path is occupied, cross-operation is influenced, is especially constructed in single-track railway tunnel, most equipment at all can not because tying up space It uses.
Existing technical solution mechanization degree is lower, and manual labor amount is big, and inconvenient, task difficulty is big, and safety is hidden Suffer from greatly, efficiency is lower;It is based only on and meets a certain process step design and have a single function, equipment effectiveness, cross-operation cannot be given full play to When interfere with each other it is big;Some excessive active channels of equipment operation influence face operation material transportation channel, so that configuration equipment Vacancy rate is higher.
