Described a kind of method for closed construction of large-area factory building equipment foundations, described building comprises vertical direction factory building crane girder or track.
The present invention has embodied the underground space and aboveground space integrated construction technology, has guaranteed the operating environment of newly-built or alteration work, for the transformation of old construction of structures provides technical guarantee.Method for closed construction of large-area factory building equipment foundations of the present invention meets domestic design commonly used at present, construction technology and execution conditions, not only saves construction investment, convenient construction greatly, has also well guaranteed the safety and the ordinary production of existing structure and equipment.For large-area factory building equipment foundations engineering or public welfare construction work, remaining silent construction provides method, the measure of practicable environmental protection and pre-control from theory into action, and economic benefit, social benefit are huge.
The specific embodiment
The present invention jumps under the polytechnic situations such as storehouse piece construction, information-based monitoring in protection, workshop steel structure installation pre-control, piecemeal well-points dewatering, cubic metre of earth piecemeal symmetry excavation, the Equipment Foundations structure of pre-control protection, existing device basis and the equipment of patten; successfully solved the weak soil large-area factory building equipment foundations remain silent construction difficult problem (as: certain engineering cold bed Equipment Foundations buried depth for-4.2m～-8.6m, part-10.0m.Foundation ditch is long to be 219.5m, and width the widest part is the construction of remaining silent of 145.8m; As certain old factory rehabilitation engineering 57m * 32.65m, the construction of remaining silent of the furnace apparatus basis of dark-9.5m).Comprise the following steps: that mainly patten or existing structure supporting (supporting of cement mixing pile block of wood, diaphragm wall and draw anchor) → Steel Structure Installation → track installs pre-control → Equipment Foundations piecemeal precipitation → Equipment Foundations and remain silent and jump storehouse method soil excavation → Equipment Foundations and jump the storehouse method structure symmetrical installation → finished product protection of the thin portion of construction → steel work pre-control adjustment → equipment of remaining silent.Particularly, necessary:
1, at first, according to cutting depth the supporting pre-control is carried out with excavation of foundation pit displacement trend direction in factory building insulated column basis:
1) for the pre-control means of cement mixing pile block of wood supporting, reinforcement depth is 3～5m under Equipment Foundations excavation face, and is wide than the wide 0.5～2m in insulated column basis, remains silent to construct for Equipment Foundations and creates good excavation condition.
2) RC Continuous wall and anchor pole have been adopted in factory building insulated column basis, and combined the construction of remaining silent of forming factory building equipment foundations under the composite support structure with the used equipment basis.
2, soil excavation unloading and symmetrical excavation and filling measure, one of soil excavation, one of structure construction, the mode that block-by-block advances are taked in the earthwork of the factory building columns and the scope of remaining silent.
3, according to soil excavation sequential partition piecemeal dewatering construction, the branch block length should be at 30m～60m, with the structure construction continuous productive process; Structure construction is taked the technology measure of " jumping the storehouse method ".
4, rationally determine steel work suspension column grouting time, construct behind the Equipment Foundations base plate remaining silent, carry out suspension column once, back-grouting, be in the milk reach design strength after, adjust track, the installation of driving a vehicle again and the equipment installation of crane girder.
5, strengthen information-aided construction, take the adjustment of pre-control means in each links such as supporting, precipitation, the earthwork, structures according to monitored data.
6, " large-area factory building equipment foundations remain silent construction technology " is the ground that is applied in the underground construction in the structure of ground of " tau-effect " principle, underground organic unity, this comprehensive technology is saved construction investment, convenient construction greatly, has economic benefit, social benefit widely.
