Description
Technical field
This utility model relates to a kind of building underground structure, especially relates to build and has basement or similar underground structure.
Background technology
Build underground structure time, prior art generally uses sheet pile, diaphram wall etc. formed retaining wall, then with
Building template in being spaced a less space between retaining wall, in the template completed, casting concrete forms underground structure
Wall.
This traditional construction method, when excavating ground, needs to dig out additional space to guarantee to build the sky required for template
Between, the answer simultaneously also resulting in earth excavation amount increases, particularly during construction in the case of urban renewal, and newly-built underground
Building usually and needs only have the most limited slight distance between the inhering architecture retained, and this exists for needing to improve effectively utilizing
The demand of rate.Additionally, this traditional construction method there is also, above-mentioned extra excavation space requirement is backfilled, before backfill
Need to carry out the soil excavated concentrating to stack, and the surface collapse after backfill settles the various problems such as uneven.
Chinese patent CN1155606A discloses a kind of by foundation side wall as basement wall and construction method thereof, this side wall by
Foundation ditch retaining wall, filling waterproof layer and interior wall composition.Retaining wall includes cantilever pile, freely-supported stake etc..Its mentality of designing is main
It is the ingredient saying retaining wall as basement guard wall, the retaining wall of gib is become permanent structure, replace reinforcing bar
Cast-in-place concrete pile.But this patent has a drawback in that, the DESIGN OF RETAINING WALLS of gib originally needs according to permanent knot
Structure is designed, and improves the cost of supporting construction, and retaining wall structure is not suitable as permanent load-carrying members, such use
The change on way may bring unpredictable hidden danger.
It is structure-integrated that Chinese patent CN103669402A discloses the piling wall that a kind of main body outer wall of basement combines with fender post
Structure, between outer wall of basement and fender post formed narrow space in, arrange along outer wall of basement side safeguard structure,
Power transmission strip etc. so that fender post acts in permanent use jointly with outer wall of basement, it is considered to subtract after the stiffness contribution of fender post
The thickness of few outer wall of underground structure, saves construction investment.But this patent still can not additionally excavate space in work progress,
And in limited narrow space, carry out building the defect of template.
Defect in view of above-mentioned conventional construction method, it is necessary to further improve the construction method of underground structure, to solve
Certainly the problems referred to above.
Utility model content
Thus setting out, one of the present utility model to solve the technical problem that and is, it is not necessary to arrange the then supporting such as retaining wall after excavation

Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is further described, but this utility model is not confined to these
Detailed description of the invention.One skilled in the art would recognize that this utility model covers the possible bag of institute in Claims scope
All alternatives, improvement project and the equivalents included.
As Fig. 1 illustrates, the part construction plan of underground structure, the soil body 1 of the surrounding of underground structure to be built is
Outside is expressed as 2, for clarity sake, in the accompanying drawings by the outermost 2 of surrounding soil 1 spaced apart with the side of building enclosure one
Individual small distance.But in Shi Gong, the outermost 2 of surrounding soil 1 can directly contact with the side of building enclosure.
According to design, on construction ground in bury underground along the outermost of the soil body 1 of the surrounding of the underground structure built and to go along with sb. to guard him corner post
11 and go along with sb. to guard him center pillar 12.Go along with sb. to guard him corner post 11, to go along with sb. to guard him center pillar 12 can be prefabrication, or water at the construction field (site) and build up
Type.Preferably go along with sb. to guard him corner post 11, to go along with sb. to guard him center pillar 12 be mill work.Go along with sb. to guard him corner post 11, go along with sb. to guard him center pillar 12 and preferably adopt
It is pressed in the soil body 1 to projected depth by static pressure mode.
Then go along with sb. to guard him corner post 11 adjacent and go along with sb. to guard him center pillar between 12 or adjacent go along with sb. to guard him between center pillar 12, by wall interior panel
13 are pressed into projected depth in the soil body.As the figures show, the end of wall interior panel 13 has protuberance 131, is suitable to and goes along with sb. to guard him
The recess 121 of center pillar 12 side engages, or the junction surface 111 going along with sb. to guard him corner post 111 engages.The most as shown in drawings,
The cross section going along with sb. to guard him center pillar 12 is I-shaped, and the cross section going along with sb. to guard him corner post 11 is that circle cuts out the shape corresponding with protuberance 131.
But optional, the cross section going along with sb. to guard him center pillar can also be other shapes, the most T-shaped, circular with recess etc., go along with sb. to guard him angle
The cross section of post can also be other shapes, and such as square is with recess etc..
Consider easily for Prefabrication, it is possible to use the prefabricated pile of other standards shape, however it is necessary that in stake surface configuration
Can be with wall interior panel 13 to the built-in fitting being connected.
As in figure 2 it is shown, wall interior panel 13 is internal can be provided with vertical and horizontal steel bar layer.At the peripheral end parts of wall interior panel 13, arrange
There is the built-in fitting being connected with steel bar layer.Preferably built-in fitting is the steel plate in strap bolt hole.So wall interior panel 13 can with go along with sb. to guard him corner post
11 and go along with sb. to guard him completed by bolt between center pillar 12 preliminary fixing.
Wall interior panel 13 preferably has the size of Modular building modulus, in order to be suitable in combination underground structure chi
Very little.
Building enclosure can use directly as the template of underground structure exterior wall, property illustrated below a kind of concrete execute is depicted
Work method, but the mode of this utility model enforcement is not limited to this and schematically describes, and skilled person will appreciate that dawn uses other
Known non-dismantling formwork or after the mode of watering implement.As after to carrying out waterproof mortar process at the gap between building enclosure, can
By the exposing surface dabbing of building enclosure, using building enclosure surface as the formwork for placing of underground structure exterior wall, then to build
