5）Locking notch pipe is gradually extracted, that is, completes the ground wall construction of a phase slot section, for completed A sections wall wall；
6）The construction of remaining all phase slot sections is carried out, construction method is the same as step 1）To 5）；
7）The construction for carrying out the second stage of slot section, by step 1）With 2）Afterwards, chute forming machine is oriented to grooving along H profile steel, in the second stage of slot section
B sections of steel reinforcement cages are hung by steel reinforcement cage hanging steel bar, and pour into a mould concrete to the elevation location at standard paragraphs foundation pit bottom, upper part is not poured
It builds, forms empty slot, rubble earthen backfill empty slot part, the as completed wall wall of the ground B sections of are used after concrete initial set；
8）The construction of remaining all the second stage of slot sections is carried out, construction method is the same as step 7）；
9）By the second stage of slot section wall is uniformly crushed to standard paragraphs foundation pit bottom when later stage earth excavation.
Further, the width of the phase slot section is the width that chute forming machine grab bucket one is grabbed, the width of the second phase slot section
The width grabbed for chute forming machine grab bucket two to three.
Further, after the adjacent phase slot section concrete intensity described two-by-two reaches 70%, the second phase in its spacing
Slot section can construct.
Further, the height of the A sections of steel reinforcement cage is more than the height of the B sections of steel reinforcement cage.
Further, the locking notch pipe is two groups, is divided into positioned at the both sides of the A sections of reinforcing bar.
The beneficial effects of the invention are as follows：
Concrete perfusion can play a supporting role to the grooving cavity of the second stage of slot section to ground when phase slot section construction of the invention,
Reduce soil at both sides to deform into cavity, while condition can be provided for the mud off grooving of the second stage of slot section；
The second phase upper ends slot section Di Qiang empty slot part of the invention backfills gravelly soil to ground, while the width of a phase slot section and the second stage of slot section
Wide also visual field condition is adjusted flexibly, and the width of a phase slot section is suitably reduced, the second stage of slot section width suitably increases, and can reduce
Filling concrete amount, at the same can also reduce later stage broken the second stage of slot section blank wall section when it is a greater part of pick chisel amount, reduce the duration and
Cost improves construction efficiency.
