The tunnel lining trolley that the utility model provides, comprises a template 1, and described template 1 structure adopts the structure of above-mentioned concrete lining template.In order to the described template 1 of the needs meeting constructing tunnel adopts arc-shaped curved surface structure (with the mating shapes of tunnel wall), build the upper surface that face 2 is template 1, also be its convex surface, described clinch 3 is positioned at one end of template 1, and the groove 31 on it and upper surface are in the same way.One end that described groove 31 and flexible clinch 32 are positioned at template 1 is arranged in described template 1 along described arc is elongated, realizes the through whole clinch of groove 31.
Provide the certain embodiments of the utility model specific implementation and application below by way of example:
Improvement of the present utility model is the template 1 of tunnel lining trolley, especially the clinch 3 of template 1, and the shape of template 1 still adopts known arc, and other structures of tunnel lining trolley all adopt prior art.
As in Figure 3-5, the template 1 of tunnel lining trolley arranges the through described clinch 3 of an elongated groove 31 for carrying out with concreting (a upper board concrete 4) bond end 5 the clinch 3 that overlaps along clinch 3 arc of template 1 end, groove 31 side is positioned at the distal edge edge of template 1, also be the few wall of groove 31, the cross section along chassis center line of whole template 1 is made to be step-like, the groove face of groove 31 is than trolley formwork plane (building face 2) low 2cm (i.e. the degree of depth of groove 31), recess width 10cm, on groove 31, (i.e. groove face) lays elastomeric material 321, elastomeric material 321 is provided with panel 322, described to plate 322 smooth surface, described elastomeric material 321, panel 322 forms elastomeric element 32.Described elastomeric element 322 comprises one deck by polyurethane elastomeric material particularly, and on polyurethane elastomeric material, bonding thick layer 3mm polyfluortetraethylene plate is as panel, thus forms composite material formation elastomeric element 32; The thickness of described elastomeric element 32 is more than or equal to the degree of depth of groove 31; Preferably described elastomeric element is trapezoidal (as shown in Figure 4) along the cross section in chassis center line direction, wherein being arranged in clinch 3 near-end (right side of Fig. 4) base is 2cm (identical with groove 31 degree of depth), be arranged in clinch 3 far-end (left end of Fig. 4) for 3cm (exceeding the face of building 2), its width is identical with groove 31 width, be anchored in groove 31 with rivet, fill whole groove 31.
Wherein, it is good that polyurethane has chemical resistance, non-corrosive; There is good self-extinguishment and anti-flammability; The features such as resistance to ag(e)ing is good, and the life-span is long.Described polyurethane elastomeric material can select polyurethane flexible foams or polyurethane hard foam as required.Polyfluortetraethylene plate (is also tetrafluoro plate, Teflon plate, Teflon plate) there is very superior combination property: high-low temperature resistant (-192 DEG C ~ 260 DEG C), corrosion-resistant (strong acid, highly basic, chloroazotic acid etc.), weather, high insulation, highly to lubricate, do not adhere to, the good characteristic such as nonhazardous.Therefore, when concrete construction, its smooth surface, is convenient to process, improves construction quality.
During use, after tunnel lining trolley is in place, make tunnel lining trolley center line and tunnel center line in same plane, then pass through adjustment side hydraulic oil cylinder, side direction leading screw is very heavy and upper very heavy, make it reach lining cutting working size, then screw very heavy very heavy with side direction.Because the elasticity clinch of tunnel lining trolley template 1 and bond end 5 soffit of a upper board concrete 4 overlap, owing to employing the elasticity clinch 32 that elastomeric material is formed, after tunnel lining trolley reaches working size, automatically ensure with a upper board concrete 4 closely connected by flexibility overlap joint, and board concrete 4 bond end 5 can not be damaged, also can not cause congratulations, save the time of artificial filling chink.
As shown in Figure 6, when template 1 and the lap length of a upper board concrete 4 just equal the width of clinch 3, and when overlap joint laminating is accurate, due to the existence of elastomeric element 32, make gapless between template 1 and a upper board concrete 4, after having built next board concrete 6, two board concretes have combined closely, and construction quality obtains effective guarantee.
As shown in Figure 7, when template 1 and the lap length just little width equaling clinch 3 of a upper board concrete 4, but when overlap joint laminating is accurate, due to the existence of elastomeric element 32, to make between template 1 and a upper board concrete 4 still gapless, after having built next board concrete 6, two board concretes have combined closely, and construction quality obtains effective guarantee.
As shown in Figure 8, when template 1 and a upper board concrete 4 can not overlap fit accurate time, namely because the impact of upper board concrete 4 construction error or the alignment error of chassis center line tunnel center line, cause the face of building 2 of template 1 can not coplanar with the soffit of a upper board concrete 4 (lower than its soffit), elongated surfaces now in the face of building 2 and on a board concrete 4 soffit between there is gap, but due to the existence of elastomeric element 32, make the gap between template 1 and a upper board concrete 4 make up by elastomeric element 32, to make between template 1 end and a upper board concrete 4 still gapless, after having built next board concrete 6, two board concretes combine closely, there will not be the existing pictures such as spillage, construction quality obtains effective guarantee.
As shown in Figure 9, when template 1 and a upper board concrete 4 can not overlap fit accurate time, namely because the impact of upper board concrete 4 construction error or the alignment error of chassis center line tunnel center line, cause the face of building 2 of template 1 can not coplanar with the soffit of a upper board concrete 4 (higher than its soffit), elongated surfaces now in the face of building 2 higher than on the soffit of a board concrete 4, namely the clinch 3 of template 1 crosses the bond end 5 pressing a board concrete 4, but due to the existence of elastomeric element 32, both can not conquassation bond end 5 concrete, also can not template 1 end and on form gapless between a board concrete 4, after having built next board concrete 6, two board concretes combine closely, there will not be the existing pictures such as spillage, construction quality obtains effective guarantee.
Due to polyfluortetraethylene plate and concrete surface closely connected, can smooth movement be ensured, eliminate the overlap joint undue influence construction quality of trolley formwork 1 and a upper board concrete in conjunction with flexible overlap joint.Because polyfluortetraethylene plate is from height lubriation material characteristic, lap-joint, without the need to brushing release agent, can not cause drawing crack phenomenon to coagulation.
Therefore, effectively can prevent and treat the concrete conquassation of tunnel double-lining lap-joint, spillage phenomenon, ensure concrete pouring quality.Efficiency of construction is high, easy to operate, saving is a large amount of artificial.
