Description
Technical field
It is more specifically a kind of pre-buried repeatable note the present invention relates to subway engineering, construction engineering technical field
Starch the ground-connecting-wall G type joints and method of pipe.
Background technology
With underground engineering fast development, design and construction ultra-deep foundation pit turns under various complicated geologicals with environmental condition
New normality.The outstanding feature that diaphram wall is big with its rigidity, good water-proof effect, construction technology are ripe, difficulty of construction is small, gradually
First-selected structural shape as Extra-Deep Foundation Pit scheme under complex geological condition.
What Deep Foundation Pit of Metro Stations ground-connecting-wall joint seal was more common at present is I-shaped steel joint, and minority uses cross steel plate
Joint geometry.
When excavating ultra-deep foundation pit process in pressure-bearing aquifer water-bearing stratum high, often there is ground-connecting-wall seam Sand dangerous situation,
Strong influence is produced to engineering construction and surrounding enviroment, often economic loss and social influence are huge.Such as, in the Wuhan mayor
River I grades of terrace regional Construction F3/B3 subway station (foundation depth is generally 24~30m), due to ground-connecting-wall seam construction matter
Amount is poor, and leak leakage sand easily occurs under high artesian head, and dangerous situation is happened occasionally, and the considerable safety as puzzlement subway construction is asked
Topic.
In order to strengthen ground-connecting-wall joint seal effect, typically take and increase at ground-connecting-wall outer side seam high-pressure rotary jet grouting pile to stop
Water, or continuous water-stop curtain (such as three axes agitating pile, plain ground-connecting-wall) is set, considerably increase construction investment.But due to working as
The limitation of preceding construction technology and construction level, the following high-pressure rotary jet grouting piles of ground 20m or three axes agitating pile construction quality are difficult to protect
Barrier, can not well solve ground-connecting-wall seam leakage problem, though anti-seepage effect is preferable when using plain ground-connecting-wall, engineering
Investment cost is high.
