Description
Technical field
The utility model belongs to the lining cutting and the muck removal technology of drilling and blasting method constructing tunnel, relates generally to the arrangement of steel form chassis and belt conveyor in a kind of drilling and blasting method constructing tunnel.
Background technology
Worker's method that tunnel construction is at present adopted mainly contains drilling and blasting method (Mine Method), (tunnel tunnel bore creeps into the machine machine to the TBM method, be called for short TBM, be used for hard rock driving and be called TBM, be used for the soft rock driving and be called the shield structure, be large-scale full bore tunnel construction equipment), three kinds of shallow burial hidden diggings etc.No matter any worker's method, its excavation is abandoned the quarrel transportation can adopt automobile transportation, rail transport, long apart from three kinds of modes such as continuous belt transportation any.In three kinds of construction means of transportation, belt transportation is effective and the most economic a kind of of long-distance transportation, so more and more trend towards employing in the constructing tunnel of growing up at present.
The tunnel is built except section excavation is shaped also needs to carry out permanent supporting, the mode of the permanent supporting in tunnel generally has 3 kinds of precast concrete pipe loop supporting (being mainly the TBM method), concrete pouring supporting (lining cutting) and fibrous concrete ejection supportings, preceding two kinds of support patterns adopt at most.Need shaping and the braced structures of steel form chassis when adopting the concrete pouring support pattern as contoured surface in the supporting and protection structure.And the steel form chassis is a kind of large-scale steel work, occupy sizable space at tunnel internal, when therefore lining cutting is adopted in the tunnel excavation construction as permanent supporting, the TBM tunnel of less cross section diameter particularly, generally all after finishing, tunnel excavation carries out the lining cutting operation again, to avoid excavating the mutual interference mutually of transportation operation and lining cutting operation.But total duration that the tunnel is built can prolong.
In order to shorten total duration that the tunnel is built, the circle, tunnel proposed synchronization lining worker method very early, i.e. tunnel excavation and lining cutting carried out synchronously, and this kind worker method is achieved in tunnel big section, that reach employing track and automobile transportation is built.But in the tunnel that adopts conveyer belt as the transportation of quarrel soil, particularly build than the tunnel of minor diameter, synchronization lining also had never been realized, reason is that conveyer belt apparatus need pass the steel form chassis, and the steel form chassis needs a circulation to connect moving forward of a circulation, but conveyer belt apparatus is fixed, and to the installation accuracy sensitivity, has the position to change slightly and promptly cause belt deviation.Therefore in the synchronization lining technical field, the long transportation with the mutual interference problem of steel form chassis apart from continuous belt fails to solve always.
Except the interference of belt transportation with steel form chassis itself, when adopting the belt transportation to abandon quarrel, also need to dispose car assisted or rail transport is used to transport the required other materials of constructing tunnel, therefore also need to keep the transport channel of automobile or track, under narrow tunnel space condition, promptly to solve the interference of belt transportation and steel form chassis itself, reserve the transport channel of automobile or track again, make the synchronization lining problem when adopting length to transport more complicated apart from continuous belt.Past was designed the multiple technical scheme that makes conveyer belt apparatus pass the steel form chassis, because of not possessing feasibility in practice, thereby all actual the employing.
Summary of the invention
The utility model proposes the arrangement of steel form chassis and belt conveyor in a kind of drilling and blasting method constructing tunnel, its main purpose just is to realize that continuous muck removal of belt conveyor in the constructing tunnel and formwork jumbo with the tunnel excavation synchronization lining, also can make the required facility of automobile or rail transport mechanical transport constructing tunnel and other material.
The following technical proposals of taking the utility model realizes its goal of the invention: the arrangement of Schaltisch and belt conveyor in a kind of drilling and blasting method constructing tunnel, the belt conveyor front end of abandoning quarrel in order to continuous conveying excavation is positioned at the excavation working region, belt conveyor by excavation working region to formwork jumbo lining cutting zone is suspended on the top in tunnel by hoist cable, and is parallel with the air chimney of constructing tunnel; The steel form chassis that carries out permanent supporting lining cutting is positioned at movable trestle construction area rear portion and is positioned on the track that connects before circulation of both sides, tunnel itself; After being positioned at the movable trestle construction area, be that the belt conveyor in the place ahead, lining cutting zone is caused ground downwards and is positioned on the cast-in-place inverted arch basis before the steel form chassis, belt conveyor is positioned at a side of formwork jumbo door frame and be arranged in parallel with transport channel by the steel form chassis time; The belt conveyor at steel form chassis rear portion is suspended on the top in tunnel by hoist cable.
The space interference problem that belt conveyor muck removal when the arrangement of steel form chassis and belt conveyor can effectively solve constructing tunnel in the drilling and blasting method constructing tunnel that the utility model proposes, formwork jumbo exist with tunnel excavation synchronization lining and hauling operation, the continuous muck removal of belt conveyor, formwork jumbo are achieved with tunnel excavation synchronization lining, vehicle borne operation simultaneously, thereby improve the efficient of constructing tunnel, shorten the constructing tunnel cycle.
