The specific embodiment:
1, as Fig. 1, rail haulage vehicle (16) gauge that the construction material transport point needs is of a size of 1900 * 2600mm (wide * height), current for realizing that rail transports four rail two-wires, consider simultaneously the train passage safe distance, the path arrangement pitch, require under the chassis door frame, the above effectively headroom of rail (18) rail level is not less than 4000 * 2800mm (wide * height).
For guaranteeing headroom in the stand, be required to be chassis and lay track specially, designed little abutment wall (2) for this reason, traveling is on as the little abutment wall in the both sides of a tunnel structure part, and the end face of this little abutment wall (2) is bottom surface, ditch, tunnel (22) (referring to Fig. 3); Chassis bottom stand (4), effective clear height 2800mm, effective clear span 4000mm can be current simultaneously for 2 row marshalings, provides condition for TBM driving and Second Lining Construction need to transport a large amount of construction materials fast incessantly.
As Fig. 1, occupy the train passage space for avoiding in the concreting process voltage regulator tube operation, influence TBM driving material and the concrete transportation of secondary lining, the present invention has designed special-purpose concrete dispenser (9) and perfect piping system, according to the concreting technological requirement, arrange pipeline on chassis, an end is connected in concrete dispenser, and the other end is installed on the concreting mouth of technological requirement.The concrete that the delivery pump pumping comes, the quantity that requires according to casting craft and building a little is assigned to exactly in the corresponding pipeline through concrete dispenser, and then sends to and build a little.
As Fig. 4, influence clear span in the train passage when avoiding the demoulding, footing mould (3) is designed to the small size turning mould, guarantees that its upset running orbit (23) can not surmount bottom girder (15) inboard.
2, as Fig. 1; TBM construction vent hose (8) diameter 2200mm, no matter need to guarantee which kind of duty lining trolley be in, but all continuous ventilatings; at chassis upper stage frame the major diameter pneumatic hose is set and walks mechanism and safeguard procedures, be i.e. pneumatic hose protection tube (7).
Arrange some rollers in the pneumatic hose protection tube, avoid air chimney directly to contact the power of effectively reducing friction with steel construction piece.The oblique transition girder of air chimney is adopted in the chassis end, reduces the resistance when walking to greatest extent.
3, as Fig. 5, in the secondary moulded lining work progress, continuous belt machine (13) all needs running continuously in any case, and the chassis zone only allows to remove the continuous belt machine at the fixing triangular support bracket (24) of hole wall.When chassis advanced, chassis the place ahead conveyor tripod need be removed by part, and the rear tripod need be installed on the hole wall that lining cutting finishes by part.
4, as Fig. 6, be fixed with belt roller supporting plate (27) on the conveyor quarter bend (25), the bottom is not a plane, can not directly walk on roller, therefore additional track (being called for short additional beam) (26) below quarter bend.Additional beam adopts hollow quarter bend to make, and weight reduction adopts Simple fastener to install, and is convenient to operation.Additional beam top keeps at a certain distance away and adds the weld pad piece, to dodge the connecting screw rod on the former conveyor quarter bend.Each is some for additional trammel lattice: 4572mm/2000mm/, causes the interference of cushion block and screw rod when preventing same specification.
5, as Fig. 6, rolling wheel support (34) can the upper and lower, left and right adjustment and effectively locking, with adapt to chassis with respect to conveyor have upper and lower to or during the relative displacement of left and right direction, conveyor can still keep original attitude constant.Rolling wheel support (34) is installed on the chassis column (19) by bolt (29), realizes the upper and lower adjustment that roller supports by double nut (30); Simultaneously, on the rolling wheel support mounting base plate (31) slotted hole is set, to adjust about the support of realization roller; After the adjustment of roller position is finished, realize effectively locking by double nut (30).
6, for to avoid the vibration in the continuous belt machine running that chassis and lining concrete structure are impacted, need simple, the obvious results damping device of project organization.As figure (5), specific practice is: between rolling wheel support (34) and rolling wheel support mounting base (32) yielding rubber piece (33) is set.If the conveyor vibration influence to concrete structure still can not be effectively avoided in this measure, special-shaped column can also be set, be installed between inverted arch prefabricated section and the turning rolls, with conduct vibrations to inverted arch prefabricated section (1).
