Description
Technical field
The present invention relates to the related fields of diaphram wall, specially a kind of construction party for underground continuous wall connector
Method.
Background technique
On the whole, diaphram wall is to build up continuous armored concrete wall together in underground, as intercepting water, prevent
Infiltration, load-bearing, water-retaining structure.Diaphram wall is formed by many wall section spelling groups, and to keep continuously constructing between wall section, connector is adopted
With locking notch pipe technique, i.e., before slot section concrete is perfused, a pre-inserted diameter and the equal steel pipe of groove width in the end of slot section, i.e.,
Locking notch pipe extracts steel pipe after concrete initial set slowly, so that end is formed half blind mortise shape and connects shape.Also with good grounds wall body structure by
Power needs and rigid joint is arranged, so that first latter two wall section unifies.Diaphram wall is first of architectural engineering
Step, quality directly affect the quality of whole building.
The shape and installation method of connector have certainly for leakage whether can occur between the perfusion slot section of underground connection wall
Qualitative effect, existing connector mostly use greatly circular tube structure, it cannot be guaranteed that the leakproofness at the slot section of two unit grooves, and two
Have between unit groove section there is a situation where leaking generation, can not achieve the anti-effect for blending water blocking in side and propose on this basis
A kind of novel construction method for underground continuous wall connector, after connector construction and installation, greatly reduce unit groove section it
Between leakage, offer convenience to the subsequent job of staff.
