Description

Old residential area comprehensive reformation method
Technical field
The present invention relates to a kind of remodeling method of old residential area, more particularly to a kind of old residential area comprehensive reformation method.
Background technology
During China carries forward vigorously urbanization, various new buildings are rised sheer from level ground, and new cell is constantly gushed in city It is existing.However there are a large amount of old residential areas in city, these old residential areas construction age is long, and infrastructure falls behind, and layout is mixed Disorderly, resident living condition is poor, and it is extremely uncoordinated to create block with surrounding.If being removed reconstruction, sustainable supervention exhibition is not met Principle.Therefore it is a very important people's livelihood engineering to carry out reasonable reformation to old residential area, has caused the extensive of the whole society Concern.
Many intrinsic methods and thinking are formed in exploring old residential area transform pattern, are mainly reflected in following two sides Face:
(1) to the improvement of cell communal facility, such as repairing cell street, increase subdistrict greening and resident playground, Street lamp is added, environment sanitation facility etc. is improved.
(2) to the improvement of cell infrastructures, such as heat insulating work, elevator is added, comprehensive pipeline is replaced in repairing, and corridor is whole It controls.
Although the present situation of old residential area after measure as above is taken to make moderate progress, could not still excavate to the maximum extent old Old cell potential value, surface is bright and new but essential problem could not solve.The transformation of old residential area cannot be only confined in old Old cell changes the level of part clothes, but it is old thoroughly to change its architecture structure form, and layout is unreasonable, and commercial value is low, Lack the Tough questions such as parking space.It solves these problems and is transformed it is necessary to start with from building itself, major embodiment At following two aspects:
1, the safety of existing building is improved by seismic strengthening technology and integral error correcting and position technology
Architecture construction in old residential area is of the remote past, and many buildings have been unsatisfactory for the requirement of current designs specification, There is integral inclined situation or even some buildings have become dilapidated house.
2, rational deployment is carried out to old residential area by displacement technique
Old residential area planning is unreasonable, one side greenery area deficiency there is no public area, on the other hand some The distance between building is unsatisfactory for current specifications fireproof requirement.It can be adjusted by existing building displacement technique old small The position of existing building in area, to be planned again old residential area.Existing displacement technique includes translation, turns to, rotation Turn, lifting, force-land, synchronize lifting translation etc..
" parking difficulty " problem is the livelihood issues most urgently solved now in old residential area, if can develop to greatest extent No matter the underground space in old lower area is used as parking lot or commercialization to promote area all by the value of significant increase old residential area Domain expanding economy, so the opera involving much singing and action of old residential area comprehensive reformation still realizes the extension of down space in large area.
The key that underground space extension is carried out to existing building is underpinning technique, and the method mainly used at present has following several Kind:1, diaphram wall is set outside skyscraper, and superstructure is underpined with beam raft;2, the wall use of list, multistory brick-and-concrete structure Sandwich wall twin beams adds anchor jacked pile to be underpined;3, list, multistory frame result by basis it is lower beat anchor jacked pile in the way of into Row underpins;
Problem of the existing technology mainly has several respects:1, the translative mode expense of diaphram wall and converted deep beam It is high;Although 2, anchor jacked pile is suitble to indoor construction, bearing capacity is limited, and pile foundation is stablized during excavating the underground space Bad control, and in the case of the more building of the number of plies will appear and lay out pile difficulty;3, anchor jacked pile is primarily adapted for use in high pressure Contracting clay or weak soil, not applicable for harder soil layer, some engineerings are replaced using large diameter bored pile, and And one or two layers floor is destroyed, such cost is just very high;4, present underground increasing layer is limited only to increase under single solitary building Layer, did not accounted for adding the underground space in flakes under groups of building, more not about add after the underground space superstructure into The design that row is made rational planning for.
