Description
Technical field
The present invention relates to tunnel immersed tube tube coupling and manufacture field, demoulding tunnel, especially a kind of self-propelled hydraulic location immersed tube tube coupling prefab-form.
Background technology
At present, in immersed tube tunnel is constructed, immersed tube tube coupling length is longer, and each tube coupling needs the trifle segmentation being divided into fixed dimension to carry out concrete pouring construction, and in tube coupling concrete pouring construction, once-pouring of concrete side's amount is bigger.Commonly used combined steel block-by-block is assembled into entirety one by one and carries out tube coupling concrete pouring construction more traditionally; this kind of method is relatively ripe; apply comparatively general; but application the method is many for immersed tube tube coupling quantity; the project that construction period is tight, then usually can because of combined steel construct its mounting or dismounting inconvenience, effect is low, personnel have high input, affect the duration, the carrying out smoothly of high etc. the engineering constraint of indirect cost.Existing combined steel construction method be applied to immersed tube tube coupling prefabricated in, because of template in construction process dismounting, the handling of reinforcing bar, colligation installation and concreting homogeneous mutual restriction on space and operation, generally all cause construction time and effort consuming, inefficiency, especially multiple tube couplings are simultaneously prefabricated, when cross-operation face is many, also easily there is security incident.In a word, existing immersed tube tube coupling prefabricated construction difficulty is big, and efficiency is low and there is bigger safety problem,.
Summary of the invention
It is an object of the invention to provide a kind of easy construction, work efficiency is high, use the self-propelled hydraulic of safety to position demoulding tunnel immersed tube tube coupling prefab-form.
Demoulding tunnel, the self-propelled hydraulic location immersed tube tube coupling prefab-form of the present invention, including overall external mold, internal mold, truss, internal mold is located between the overall external mold of the left and right sides, it is characterized in that, main walking dolly is installed in the lower end of overall external mold, main walking dolly is contacted with long rails by lengthwise rows travelling wheel, lengthwise rows travelling wheel is driven by drive motor and change speed gear box, main walking dolly is provided with cross track, horizontal walking dolly is contacted with cross track by horizontal road wheel, horizontal road wheel is by horizontal hydraulic oil cylinder driving, horizontal walking dolly is connected with overall external mold by hoist cylinder, hoist cylinder controls the above-below direction motion of overall external mold, horizontal road wheel controls the transverse movement of overall external mold, lengthwise rows travelling wheel controls the lengthwise movement of overall external mold；Having connecting hole on long rails, the column of overall external mold is fastenedly connected with long rails by fastening bolt through connecting hole；The overall outer mold top of the left and right sides connects by truss is fixing, internal mold is reinforced by ground anchor bolt location, internally installed to support strut, the immersed tube tube coupling reinforcing bar of colligation molding is between overall external mold and internal mold, and the immersed tube tube coupling reinforcing bar both sides of colligation molding adopt wooden model closure.
The using method of demoulding tunnel, the self-propelled hydraulic location immersed tube tube coupling prefab-form of the present invention:
1, on pre-aligned good base plate, first carry out the colligation molding of immersed tube tube coupling reinforcing bar；
2, in advance assembled good overall external mold is in place along the immersed tube tube coupling reinforcing bar limit marching to colligation molding on the good long rails of pre-plugged, internal mold is in place by gantry crane lifting；
3, overall external mold and internal mold first carrying out the location of upper and lower absolute altitude, then carries out horizontal boundary alignment, check, by measuring instrument, the position that overall external mold is relative with immersed tube tube coupling reinforcing bar, location completes；
4, behind integral mold plate location, fastening bolt is used to tighten fixing by the sole of overall external mold column and long rails, the overall outer mold top of the left and right sides connects by truss is fixing, internal mold is reinforced by ground anchor bolt location, internally installed to support strut reinforcing, reinforcing completes, and the both sides of immersed tube tube coupling reinforcing bar adopt wooden model closure；
5, immersed tube tube coupling is layered from bottom to top by base plate to abutment wall and carries out casting concrete, adopts pump truck machinery to enter mould, mechanical packing；
6, concreting is complete, according to concrete strength requirement, determine the demoulding time, after rebound test reaches normal intensity, first the truss at top is removed, start hydraulic power unit, control overall external mold transverse direction oil cylinder and carry out the demoulding, remove the connection fastening bolt between overall external mold column and long rails again, control the hoist cylinder of overall external mold, after making overall external mold depart from long rails certain altitude, start drive motor and change speed gear box, longitudinal main walking dolly of traction drive steadily moves to next group tube coupling along immersed tube tube coupling axial direction with overall external mold longitudinally track, internal mold is carried out lifting by straddle truck and removes to next group tube coupling；
The immersed tube tube coupling built is carried out water seasoning after removing by interior external mold, and curing concrete more than 14 days, subsequently into subsequent cycle.
When demoulding tunnel, the self-propelled hydraulic location immersed tube tube coupling prefab-form of the present invention uses, concrete pouring construction, without frequently dismounting punching block, improves effect, reduces influencing each other between intersection operation, reduce potential safety hazard, overall transhipment after the demoulding, decreases artificial a large amount of inputs, has saved time and construction period, concreting process adopt pump truck machinery enter mould, mechanical packing, whole work progress safety is fast, and makes construction quality obtain effective guarantee.
