A kind of reverse construction mechanical device
Technical field
The present invention relates to a kind of novel reverse construction Machine Designs.
Background technology
Contrary sequence method:First along building basement axis or surrounding construction diaphram wall or other supporting construction, build simultaneously
Building inside object has off position to pour or lay intermediate sup-poning pile and column, and top is born before bottom plate back cover as construction period
The support of dead load and construction loads.Then the beam slab floor structure of one layer of construction ground, very as diaphram wall rigidity
Big support then successively downward earth excavation and pours each layer underground structure, until bottom plate back cover.Simultaneously as ground one
The floor structure of layer is completed, and condition is created for Superstructure Construction, it is possible to while successively carrying out superstructure upwards
Construction.Such ground is carried out at the same time construction above and below, until engineering terminates.
The advantages of contrary sequence method:
1. construction and the underground infrastructures construction parallel stereo operation of building superstructure can be made, in construction scope
Greatly, when upper and lower level is more, working hour 1/3 can about be saved.
2. stress is well reasonable, building enclosure deflection is small, thus the influence to adjacent building is also small.
3. construction can be lacked by weather, and earth excavation can be less or account for total lever factor substantially.
4. utilizing the underground space to greatest extent, expand basement construction area.
5. one layer of structural plan can be used as workbench, it is not necessary in addition set up and excavate workbench and inner support, so substantially
Degree reduces the temporary projects such as support and workbench, reduces operating expenses.
6. since that excavates and construct staggeredly carries out, inverse itself load for making structure is directly taken on by column and is transferred to ground
Base, influence of the unloading to supporting course, reduces ground springback capacity in foundation pit when reducing heavy excavation.
It is insufficient existing for contrary sequence method:
1. problem of cutting the earth:Since underground floor height limits, small-sized digging machine is needed either to cut the earth by manpower.But
Often lacking small-sized machine under normal circumstances, therefore big machinery and manpower can only be relied on to cut the earth, big machinery is inconvenient to use,
Manpower is cut the earth inefficient, is only made up with tactics of human sea, the time takes 24 hours, be to sacrifice labour cost as generation in this way
Valence.Shoveling is carried out under top seal state, and a certain number of middlebearing columns and precipitation well point are also distributed in foundation pit
Pipe still lacks small-sized, flexible, efficient small-sized digging machine, the difficulty of shoveling is made to increase.
2. underground floor height limits:Contrary sequence method Support Position is limited by basement floor height, height can not be adjusted, in case of larger
The basement of floor height needs separately to set section and arrangement of reinforcement interim horizontally-supported or that increase enclosure wall sometimes.
3. the reinforcement at hole of constructing:If it is " closed contrary sequence method " is used, earthwork when construction downwards transports, material
Transport and be required for reserving one or two larger construction mouth at floor layer, to ensure to construct, mouth is normally carried out, necessary later
Consolidation process is carried out, certain expense is needed.
Domestic and international present Research, level and development trend:Contrary sequence method is promoted and applied, the safety of underground engineering can be improved
Property, can greatly save project cost, shorten the construction period, prevent around ground sink, be a kind of rising
With the multiple material handling method of deep foundation pit of promotional value, reverse construction skyscraper depth base is applied in Liaoning, Shanghai, this kind of area in Guangzhou
It cheats more.It is more typical to have Shanghai special type foundation engineering research institute office building, it is located at roads in southwestern Shanghai angle Xujiahui day key bridge.It should
2 layers of building underground, 5 layers on the ground, bottom plate buried depth is -7.30m.It is applied simultaneously with superstructure to explore foundation structure
Work, to shorten total time of construction, building uses Top-down Construction Technique and achieves success.For another example, it is built by Shanghai second
The perseverance product Building of engineering company's construction is built with 4 layers of reverse construction underground, 22 layers, foundation pit depth 17m of ground, construction is only used
5 months, the entire duration obviously accelerated, and reduced 4,000,000 yuan of support expense, and periphery pipe settlement is only 15mm, surrounding road and
Residential house displacement achieves significant economic benefit and social benefit within 5mm.Thus it is inverse one has been started in District of Shanghai
Practice heat, has thereafter the tens of engineerings such as square tomorrow, Jing Shazhu sparetime universities tall building to use reverse construction in succession.
Currently, contrary sequence method has issued the National Standard of the People's Republic of China's building foundation design for being included in and promulgating for 2001
Specification;Various regions also disclose basement top-down method construction successively(YJGF02-96)With(YJGF07-98), thus can be explained
Reverse construction has reached its maturity, having very promising prospects in deep foundation pit support.If when eighties of last century is contrary sequence method starting
Phase, after and then rapidly developing and widely apply in China, nowadays it is in the technology maturation phase, it will has bigger
The period of full bloom of development.
