Line nigger is connected, meanwhile, cage bar silk head of the bottom ground-connecting-wall steel reinforcement cage cage bar in docking region is lengthening silk head, in docking
Before, the nigger is screwed in into the bottom ground-connecting-wall steel reinforcement cage cage bar, during docking, then nigger screw-in is described
Lengthways main steel bar silk head length in top ground-connecting-wall steel reinforcement cage cage bar, therefore bottom ground-connecting-wall steel reinforcement cage cage bar docking region
It is identical with nigger length.
Further, the length of the nigger is between 75mm-110mm.
Further, the top ground-connecting-wall steel reinforcement cage and the bottom ground-connecting-wall steel reinforcement cage add in processing platform segmentation
Work.
In order to solve the above problems, present invention also offers a kind of construction party for improving ground-connecting-wall steel reinforcement cage joint quality
Method, it is adaptable to above-mentioned ground-connecting-wall steel reinforcement cage, comprises the following steps：（1）Lift by crane ground-connecting-wall steel reinforcement cage；（2）Ground-connecting-wall steel reinforcement cage master
Muscle is docked；（3）Steel reinforcement cage cage bar docks region horizontal bar and drag hook muscle is installed and transfers top ground-connecting-wall steel reinforcement cage, wherein：
The step（1）In ground-connecting-wall reinforcement cage hoisting, reasonable Arrangement hoisting point position is become with reducing ground-connecting-wall reinforcing bar cage hoisting
Shape, with the maximum sagging moment of ground-connecting-wall steel reinforcement cage with it is maximum hogging moment is equal is advisable, meanwhile, ground-connecting-wall steel reinforcement cage is using reinforcement truss
Mode improves the integral rigidity of ground-connecting-wall steel reinforcement cage, reduces the deformation of ground-connecting-wall reinforcing bar cage hoisting；
Step（2）Bottom ground-connecting-wall steel reinforcement cage is lifted into groove in advance, and is held on regulation jack top by I-steel shoulder pole,
Upper back ground-connecting-wall reinforcement cage hoisting, it is in place after artificial righting, then adjust bottom ground-connecting-wall steel reinforcement cage by adjusting jack
Posture, reduces two sections ground-connecting-wall steel reinforcement cage cage bar silk head spacing, then connects.
It is an advantage of the invention that：
Complete set is provided the invention provides a kind of ground-connecting-wall steel reinforcement cage easily docked, and for the ground-connecting-wall steel reinforcement cage
Construction method is docked, the problem of joint quality difference, improves ground when efficiently solving ground-connecting-wall steel reinforcement cage section construction lifting
Connect the globality of wall steel reinforcement cage, it is ensured that the stress performance of ground-connecting-wall in Excavation Process, it is ensured that excavation of foundation pit safety.
