Abstract
The utility model provides an underground continuous wall. The technical scheme adopted by the underground continuous wall is as follows: the underground continuous wall comprises an underground continuous wall body; a root stud for supporting is arranged at one side of the underground continuous wall body. The root stud is arranged at the outer side of the underground continuous wall body and at the inner side of the underground continuous wall body. The benefits of the underground continuous wall are as follows: the root stud and the underground continuous wall are constructed at the same time; the overall stability is good; the anti-bending capacity is good; the bearing capacity at horizontal direction is increased through bondability of the earth body on the root stud; the underground continuous wall provides possibility of reduced horizontal supporting or non horizontal supporting, thereby having better economical efficiency, simple process, rapid construction and good safety and reliability.
Description
One, technical field
The utility model relates to a kind of structure of diaphragm wall.
Two, background technology
The diaphragm wall excavation technology originates from Europe.It is to use the method for mud and tremie concrete to grow up according to well-digging and oil drilling, nineteen fifty has at first been adopted the slurry coat method construction of diaphragm wall at Milan, ITA, this technology of 50-60 age in 20th century obtains promoting at the western developed country and the former Soviet Union, becomes otherwise effective technique in the construction of underground construction and deep foundation.At present, construction method of underground continuous wall is the diaphragm wall of constructing earlier, successively excavates then, and construction successively is interior to be supported, and treats interior support maintenance after the Intensity Design value, one deck earthwork under could excavating.This method engineering time is longer, and does not make full use of foundation ditch surrounding soil intensity.
Three, summary of the invention
The utility model provides the layout method of a kind of key formula continuous underground wall structure.
Technical solution adopted in the utility model is: a kind of diaphragm wall, comprise the diaphragm wall body of wall, and be provided with passive key in described diaphragm wall body of wall one side.
Described key is arranged on the external side of underground continuous wall.
Described key is arranged on diaphragm wall body of wall inboard.
The beneficial effects of the utility model are, root key and diaphragm wall are constructed simultaneously, resistance to overturning is good, bending resistance is strong, utilize the soil body that the bond stress of root key has been increased the horizontal direction supporting capacity, provide possibility for reducing horizontal support or not establishing horizontal support, thereby had better economy, technology is simple, quick construction, safe and reliable.
Four, description of drawings
The wall body structure schematic diagram of Fig. 1 diaphragm wall
1 diaphragm wall body of wall, 2 medial root keys, 3 lateral root keys among the figure
Five, the specific embodiment
Of the present invention key formula continuous underground wall structure is made up of diaphragm wall body of wall 1 and root key, and it is medial root key 2 or to be arranged on the diaphragm wall outside be lateral root key 3 that the root key can be arranged on the diaphragm wall inboard, when being arranged at the inboard, should progressively knock out with excavation.When the outside allows, should be arranged on the outside, needn't knock out with excavation.Medial root key 2 can level run through, as supporting in the diaphragm wall.The root key degree of depth and spacing need to determine by calculating according to engineering properties, geology and ambient conditions.
Claims (3)
1. a diaphragm wall comprises the diaphragm wall body of wall, it is characterized in that, is provided with passive key in described diaphragm wall body of wall one side.
2. a kind of diaphragm wall as claimed in claim 1 is characterized in that, described key is arranged on the external side of underground continuous wall.
3. a kind of diaphragm wall as claimed in claim 1 is characterized in that, described key is arranged on diaphragm wall body of wall inboard.
