Then, vertical lifting device and side direction stretching device is utilized to carry out formwork.As shown in Figure 1, the detailed process of formwork comprises the following steps: first, drive described top template 110 in the vertical direction to rise by described vertical hydraulic jack 151 and decline, after treating that described top template 110 in the vertical direction reaches requirement for height, by described vertical connection support screw, described top template 110 is vertically located; Then, described upper side template 121 is driven to overturn along underground passage horizontal direction (transverse direction) by upper hydraulic jack 163, after treating that described upper side template 121 turns to assigned position, adjust screw mandrel 164 by the upper support be fixed on described upper side template 121 and located lateral is carried out to it; Afterwards, by described lower hydraulic jack 161 and upset hydraulic jack 165 drive described lower side template 122 along underground passage horizontal direction (transverse direction) upset with stretch, described lower side template 122 and upper side template 121 are in line shape substantially; After treating that described lower side template 122 turns to assigned position, adjust screw mandrel 162 by the lower support be fixed on described upper side template 121 and located lateral is carried out to it; Then, vertical supporting screw mandrel 166 is installed, and by described vertical supporting screw mandrel 166, described lower side template 122 is vertically located, finally, diagonal brace screw mandrel 191 is installed to improve the stability of described support replacement formula formwork jumbo 100 in formwork state, prevents described support replacement formula formwork jumbo 100 from after formwork, occurring transverse shifting.
As shown in Figure 1, one end of described vertical supporting screw mandrel 166 is directly bearing on concrete surface, the other end of described vertical supporting screw mandrel 163 is fixedly connected with described lower side template 122, lower side template 122 described in the supporting and fixing of described vertical supporting screw mandrel 166 in the vertical direction, after formwork, described side template 120 and the distance h3 bottom underground passage are generally less than the height h2 of described internal support of foundation pit system 20, described support replacement formula formwork jumbo 100 width L after formwork completes can reach more than 15 meters, height H can reach 6 meters, and length can reach 30 meters.
Afterwards, concreting is to form structure side wall and structure roof simultaneously.
After concrete intensity meets the demands, vertical lifting device and side direction stretching device is utilized to carry out receipts mould.Receiving mould is implement according to the order contrary with formwork.As shown in Figure 5, before the described side template 120 of contraction, first be fixed on upper supports adjustment screw mandrel 164 on described upper side template 121 and the script vertical supporting screw mandrel 166 be fixed on described lower side template 122 all unclamps by the lower support be originally fixed on described lower side template 122 adjustment screw mandrel 162, originally, make described side template 120 can free shrink; Afterwards, shrink described side template 120 by described side direction stretching device, the side that described side template 120 shrinks rear described support replacement formula formwork jumbo 100 is less than the Internal periphery size of underground passage side; Then, by described vertical hydraulic jack 151, described top template 110 is declined, after described top template 110 declines, the top of described support replacement formula formwork jumbo 100 is lower than the Internal periphery size at underground passage top.
After receiving mould, the outer profile size of described support replacement formula formwork jumbo 100 is less than the Internal periphery size of underground passage, and described side template 120 is higher than described internal support of foundation pit system 20.Incorporated by reference to reference to figure 5 and Fig. 6, the width L ' of described support replacement formula formwork jumbo 100 and height H ' be all less than the size after formwork, described side template 120 receive after mould with underground passage bottom distance h3 ' more than 2 meters, and the distance bottom described internal support of foundation pit system 20 and underground passage, namely the height h2 of described internal support of foundation pit system 20 is below 1.7 meters, and therefore described side template 120 is positioned at the top of described internal support of foundation pit system 20.After receipts mould terminates, cleaning brush oil is carried out to described top template 110 and side template 120.
Then, lay the track 171 of next construction cell, and walking on the track 171 utilizing described running gear to drive described support replacement formula formwork jumbo 100 to lay along underground passage axis direction (longitudinal direction), described support replacement formula formwork jumbo 100 is moved to next construction cell, repeats above-mentioned steps.
Incorporated by reference to reference to figure 1 and Fig. 5, dismounting diagonal brace screw mandrel 191 is needed before described support replacement formula formwork jumbo 100 moves, and lateral connection positioning screw rod 192 is installed to improve the stability of described support replacement formula formwork jumbo 100, described lateral connection positioning screw rod 192 described support replacement formula formwork jumbo 100 arrive next construction cell and complete laterally in place after dismantled again.
When described support replacement formula formwork jumbo 100 moves, by carrying out alternately Assembly And Disassembly to described walking support replacement device, described underground passage inner support system 20 can be avoided when described support replacement formula formwork jumbo 100 is vertically moved, thus arrive next construction cell smoothly.
When adopting the support replacement formula formwork jumbo 100 of the embodiment of the present invention to carry out concreting, underground passage structure roof and structure side wall can one-time-concreting shaping, and deep foundation ditch inner support system need not be removed.Meanwhile, because top template can be declined automatically by lifting gear, reduce the dismounting difficulty of top template in underground passage.
To sum up, in the support replacement formula formwork jumbo provided in the embodiment of the present invention and the construction method of underground passage concreting, top template and side template are adjusted to the right place by vertical lifting device and side direction stretching device by described support replacement formula formwork jumbo respectively, the demoulding and a mold process are implemented primarily of plant equipment such as hydraulic jacks, manual operation amount reduces greatly, and by being installed on the walking support replacement device on described support plinth assembly, make described support replacement formula formwork jumbo can get around internal support of foundation pit system in underground passage when mobile, therefore the concreting when not removing internal support of foundation pit system, make structure roof and the one-shot forming of structure side wall of underground passage, thus reduce construction technology and duration, save labour and construction cost, improve efficiency of construction.
Foregoing description is only the description to present pre-ferred embodiments, any restriction not to the scope of the invention, and any change that the those of ordinary skill in field of the present invention does according to above-mentioned disclosure, modification, all belong to the protection domain of claims.
