Description

A kind of prefabricated ground-connecting-wall with limiting card groove plate joint
Technical field
This utility model belongs to goes along with sb. to guard him construction field under building, more particularly to a kind of company prefabricatedly that can be independently spacing Wall.
Background technology
With the economic continuous improvement developed rapidly with the level of urbanization, urban issues becomes increasingly conspicuous, such as densely populated, Traffic congestion, resource exhaustion, using area not enough, land price is surging etc..Using the underground space configuration urban infrastructure be from The effective way of issues about the cities' development is fundamentally solved.At present, underground space building enclosure is most commonly used that diaphram wall.
However, as cast-type diaphram wall is irrigated under water, inevitably there is some defects and disadvantage.
First, concrete setting is waited to cause claim for eot
Used as underground large-sized concrete supporting construction, earth excavation needs to wait diaphram wall to mix cast-in-place diaphram wall Solidifying soil solidifies and further can construct after reaching some strength, and urban underground space construction requirements are tried one's best the reduction of erection time, existing Pour the rapid construction requirement that ground-connecting-wall does not obviously meet urban underground space construction.
When the 2nd, pouring, quality is difficult to ensure
During the underwater casting of ground-connecting-wall, concrete easily presss from both sides mud, is stained with mud during descending reinforcing cage on reinforcing bar, reduces concrete Bonding strength, wall body difficult quality guarantee, and easily cause the random infiltration of metope, this is that cast-in-place ground-connecting-wall cannot be solved always A difficult problem certainly.
3rd, in soft stratum, degree of plainness for wall surface is wayward
When soil layer weakness or layer of sand, if mud conditioning is improper, cell wall there are problems that caving in, it can be common that metope has outer Show especially as the problems such as degree of plainness for wall surface is difficult to control to.
Existing there is also some examples using prefabricated ground-connecting-wall, some defects above can be avoided, but pre- at present The use of ground-connecting-wall processed is not extensive, when installing decentralization between its chief reason or two panels body of wall, due to the peace of seam crossing Holding position and installation effect are wayward, cause edge joint position stagnant water effect poor, and the connection effect of body of wall hardly results in guarantee.
Utility model content
The purpose of this utility model is to provide a kind of prefabricated ground-connecting-wall with limiting card groove plate joint, solves cast-in-placely even Wall exist wait concrete setting when causing claim for eot, pouring quality be difficult to ensure and soft stratum in degree of plainness for wall surface be difficult The technical problem of control, also solves the installation site of prefabricated ground-connecting-wall wall width and installation effect is wayward deviation occurs, lead Cause edge joint position stagnant water effect is poor, and the connection effect of body of wall hardly results in the technical problem of guarantee.
