Abstract
The invention discloses a novel tunnel slagging method, which belongs to the tunnel engineering construction technology. The invention provides a forming method of a belt conveying system which is simple to install and easy to extend and used for tunnel slagging with mining method construction. The method is characterized in that the belt conveying system is formed by mutually lapping multiple independent belt machines end to end, wherein in lapping, the tail of the previous belt machine is on the head of the next belt machine, the lapping length is 15-30 cm, the length of each independent belt machine is 3-5 m, and the belt machines are electrically driven. The front end of the entire belt conveying system is located in a tunnel excavation work area, and the tail of the belt conveying system is located outside the tunnel. An independent belt machine is lapped on the front end of the belt conveying system close to the tunnel excavation surface at each time of tunneling so as to synchronize the excavation, slagging and lining processes in the tunnel construction with a mining method.
Description
Technical field the invention belongs to the tunnel construction technology
Background technology tunnel construction method is divided into TBM and Mine Method.The mode of slagging tap of TBM adopts the belt transmission of being fixed on the TBM equipment, be characterized in driving along with TBM, the belt that is fixed on the TBM is sent to the dregs of its excavation outside the hole incessantly, utilizes after treatment or discards, and slags tap and excavate operation simultaneously in the tunnel.
The mode that the Mine Method construction tunnel is slagged tap is generally rail transportation, trackless transportation and belt transmission.Rail transportation construction environment close friend, trackless transportation severe contamination construction environment, when slagging tap with this dual mode, other operations stay cool substantially.The belt transmission is not only environment-friendly, and is the most effective means of transportation, but the transmission of existing belt mostly is fixed mode, and there is unsurmountable problem in belt transmission device when the driving with the tunnel extends forward: need the long period to move or adjust belt dressing.
The tunnel (hole) that patented technology 200810141301.0 proposes is muck removal continuously, the synchronous job practices of lining cutting and excavation places the excavation working region with the belt conveyor front end, place on the inverted arch prefabricated section or be suspended on the top in tunnel by the belt conveyor in excavation working region to steel form chassis lining cutting zone, be put on inverted arch prefabricated section or the cast-in-place inverted arch basis at the place ahead of steel form chassis belt conveyor, make conveyer be positioned at formwork jumbo door frame inboard when emphasizing to handle by formwork jumbo, has falsework in the formwork jumbo front, it is positioned on the track that connects before the steel form chassis circulation itself, belt conveyer passes behind the steel form chassis its top that is positioned on the inverted arch prefabricated section by lining cutting operating area to tunnel face or is suspended on the tunnel, thereby realizes that the continuous muck removal of belt conveyor in the constructing tunnel and formwork jumbo are with the tunnel excavation synchronization lining and make automobile or facility and other material that rail transport mechanical transport constructing tunnel is required.The same existence of this invention needs the long period to reset the problem of conveyor.
This shows that the Mine Method construction tunnel is slagged tap needs a kind of installation simple, easily the belt transmission system of extending.
Summary of the invention purpose of the present invention realizes by following approach: the belt transmission system of slagging tap in the tunnel by several independently conveyor head and the tail mutually overlap joint form, during overlap joint, the afterbody of last conveyor in the above, the head of back one conveyor below, lap length is 15 ~ 30cm, each independently conveyor length be 3 ~ 5m, by driven by power.The front end of whole belt transmission system is positioned at the tunnel excavation workspace, and the afterbody of belt transmission system is positioned at outside the hole, tunnel.Along with the driving in tunnel, overlap an independently conveyor at front end near the tunnel excavation face at every turn.
The present invention has following characteristics: 1) slag tap and other operation parallel operations in the tunnel, improves the construction speed in whole tunnel; 2) construction environment close friend, because belt transmission system is by driven by power, can not produce harm to construction environment, conventional drilling and blasting method just can begin the boring and the operation of slagging tap after looking for the top finishing to ventilate, and this safety for tunnel engineering and health to pay attention to day by day is also extremely important; 3) assembly and disassembly are simple, because each belt conveyor in light weight independently, two people in minutes just can finish assembling operation; 4) can leaping over obstacles, adapt to various landform; 5) convenient transportation, common container-type transportation gets final product; 6) cost is low, and is easy to maintenance.
The specific embodiment 1) along on the inverted arch of tunnel side wall a plurality of independently conveyors being overlapped mutually, joins end to end.During overlap joint, the afterbody of last conveyor is last, and the head of a back conveyor is descending lap length 15 ~ 30cm; 2) the belt transmission system front end that whole overlap joint is good places the excavation workspace in tunnel, and the afterbody of belt transmission system places outside the hole, tunnel; 3) be equipped with a dress slag equipment in the excavation workspace dregs of excavation is delivered on the belt transmission system, can transport to outside the hole, tunnel by belt transmission system; 4) along with the circulation each time of tunnel excavation, on the front end overlap joint of belt transmission system one independently conveyor can realize that belt transmission system extends forward with tunnel piercing; 5) when needs are crossed over or are walked around between other operation areas, with the independent conveyor of this segment overlap joint (increasing independent conveyor in case of necessity) again on demand.
