Abstract
The utility model relates to the field of pouring tunnel double-lining concrete, in particular to a tunnel double-lining concrete trolley blocking head formwork reinforcing structure which solves the problem that an existing blocking head template is unreasonable in support, serious in formwork shifting, faulting in slab ends of lining slab joints after form removal and unable to be used repeatedly. The tunnel double-lining concrete trolley blocking head formwork reinforcing structure comprises an annular fixed frame annularly fixed tightly attached to the edge of an arc ring mould of a lining trolley, wherein a clamping gap for a blocking head formwork is reversed between the annular fixed frame and the lining trolley. The tunnel double-ling concrete trolley blocking head formwork reinforcing structure further comprises steel tube support beams annularly fixed on the lining trolley at intervals, a reinforcing steel bar where an end of the blocking head formwork is inserted and a reinforcing inclined support abutting against the inner side of the blocking head formwork. When the tunnel lining trolley constructs, the formwork reinforcing structure enables the blocking head formwork to be convenient, quick, stable, safe and reliable to operate and enables a double-lining blocking head formwork to be reasonable and firm. The tunnel double-lining concrete trolley blocking head formwork reinforcing structure is integrated with a trolley, can be used repeatedly, quickens construction speed, saves material cost and improves construction safety and structural stability.
Description
Technical field
The utility model relates to tunnel double-lining concreting field, is specially a kind of tunnel double-lining concrete chassis stopper formwork reinforcement structure.
Background technology
Country rock is ever-changing behind the tunnel excavation, for supporting after in time satisfying fast tunnel excavation becomes circulating application worker requirement, prevent that the tunnel from caving in, must catch Best Times to finish the supporting Cheng Huan of the rear weak surrounding rock of excavation, behind excavation, original country rock equilibrium state is broken, peripheral rock and vault have produced plasticity variation and lax, in order to stop by the over-travel of the country rock after the excavation disturbance and distortion, reduce and sink and convergence, must there be rational supporting and protection structure to retrain the pressure that bears country rock.Traditional method is to use the bow member supporting, set anchor tube (bar), hang reinforced mesh, concrete spraying support, after just finishing, and then will construct two the lining concrete, just can finish the last supporting in tunnel, as the tunnel contour moulding form, the termination adopts the stopper wooden form to reinforce, because the tunnel is longer by lining trolley (generally long 12m) in two lining concretings, whenever build the 12m that advances, will dismantle once the stopper template, reinforce again once when building next plate, repeat above operation until tunnel double-lining is finished.Stopper formwork reinforcement speed, quality, be directly to affect in speed of application, the concreting operation under pressure, the distortion of trolley formwork toe-in causes liner plate seam faulting of slab ends, and the tunnel plate sews up smooth-going success or failure.
Traditional method is, after chassis was in place, stopper template from bottom to top annular was reinforced, and supports while reinforcing, after the form removal, the stopper template does not reach recycling, causes the wooden form waste, and the activity duration is long, and the stopper shuttering supporting is unreasonable, the race mould is serious, and liner plate seam faulting of slab ends must repairing could satisfy the planeness requirement after the form removal.
Summary of the invention
The utility model is unreasonable in order to solve existing stopper shuttering supporting, runs mould serious, and liner plate seam faulting of slab ends after the form removal, and the problem that can't reuse provide a kind of tunnel double-lining concrete chassis stopper formwork reinforcement structure.
The utility model is to adopt following technical scheme to realize: a kind of tunnel double-lining concrete chassis stopper formwork reinforcement structure, comprise and be close to lining trolley arch ring mould edge ring to fixing annular fixing frame, reserve the fixing gap of stopper template between annular fixing frame and the lining trolley, also comprise spacer ring and insert the reinforcing bar retainer ring of laying and the reinforcing diagonal brace that holds out against with stopper template inboard to the steel pipe support beam, the confession stopper form stop that are fixed on the lining trolley.Adopt structure design of the present utility model, stopper template one end and splash guard hold out against, in the fixing gap between one end insertion annular fixing frame and the lining trolley, the steel pipe support beam that arranges can be played the reinforcement supporting role, reinforcing bar retainer ring and reinforcing diagonal brace play auxiliary reinforcement effect.
Be provided with timber wedge between described stopper template and the annular fixing frame, can further lock template.
The added pile platform that is provided with of described steel pipe support beam, the pile platform outside is hung with safety guard net, can be placed on after the form removable on the pile platform, and safety guard net can guarantee construction safety simultaneously.
Compared with prior art, when the utility model provides a kind of tunnel double-lining chassis construction, the stopper template is easy, rapid, firm, the reliable formwork reinforcement structure of job safety, make two lining stopper templates more reasonable, more firm, form integral body with chassis, and can reuse, can guarantee that physical dimension meets design requirement, under the concrete pressure effect, not cause the distortion of trolley formwork toe-in, cause concrete lining plate seam faulting of slab ends, accelerate speed of application, the economical with materials cost has improved the stability of working security and structure.

The specific embodiment
A kind of tunnel double-lining concrete chassis stopper formwork reinforcement structure, as shown in Figure 1, 2, comprise and be close to lining trolley 1 arch ring mould edge ring to fixing annular fixing frame 2, reserve the fixing gap 3 of stopper template 7 between annular fixing frame and the lining trolley, be provided with timber wedge 8 between stopper template 7 and the annular fixing frame 2, also comprise spacer ring and insert the reinforcing bar retainer ring 5 of laying and the reinforcing diagonal brace 6 that holds out against with stopper template inboard to the steel pipe support beam 4, the confession stopper form stop that are fixed on the lining trolley.The steel pipe support beam 4 added pile platforms 9 that are provided with, the pile platform outside is hung with safety guard net 10.
During concrete the making, the stopper template is comprised of the plank of some thick 50mm, and template length is greater than lining thickness, and every width selects 30 ~ 40cm to be advisable, and is convenient to operation; The steel lining trolley is by factory process, splicing assembles at the scene, walking is moved by rail, behind the measurement and positioning, mounting block head mould plate, build two lining during Concretes generation race moding shapes for not making, adopt the annular fixedly steel pipe of Φ 42mm as annular fixing frame, be close to along the chassis edge ring to being welded and fixed as support, insert the support of laying as the stopper template, install for strengthening supporting, make the steel pipe support beam every 1.2 ~ 1.5m with Φ 80mm steel pipe, squeeze between the annular fixedly steel pipe of Φ 42mm and the stopper template locking with timber wedge; After the form removal stopper template is deposited on the pile platform, reuse next time, for construction safety, the outer side mounting safety guard net of pile platform, in addition, the stopper template is reinforced by reinforcing diagonal brace, and the reinforcing bar retainer ring plays auxiliary reinforcement effect, the stopper template back side can arrange ribs, and the stopper template is played the connection supporting role.
