Layer carries out grabbing native grooving.
Specific step is as follows for the above method:
Step 1 directly carries out grooving operation using chute forming machine in the softer ovum gravel erratic boulder stratum in diaphram wall top；
Step 2, construction stop grooving operation when arriving soft or hard strata interface, apply the perpendicular drilling of brill with rotary drilling rig, apply brill
Bouncing of drilling tool construction is carried out in the process；
After the completion of brill is applied in step 3, perpendicular drilling, the grab bucket of chute forming machine two drills into harder ovum gravel erratic boulder respectively along adjacent erect
It carries out grabbing native grooving operation in stratum；
Step 4, complete diaphram wall construction of foundation ditch after, complete the construction of diaphram wall.
As a further solution of the present invention, after the softer ovum gravel erratic boulder stratum being hollowed out, chute forming machine is directly utilized
Grooving operation is carried out, bores the perpendicular drilling of multiple extensions applying at groove location, perpendicular drilling underground along harder ovum gravel erratic boulder stratum
The entire depth of diaphragm wall foundation trench extends.
As a further solution of the present invention, the perpendicular drilling apply boring by rotary drilling rig forms.
As a further solution of the present invention, the perpendicular drilling all constructs to be formed using bouncing of drilling tool.
As a further solution of the present invention, 0.8 meter of the aperture of the perpendicular drilling, adjacent 2~3 meters of the perpendicular spacing of wells.
As a further solution of the present invention, the quantity of the perpendicular drilling is two and is located at chute forming machine two sides grab bucket lower section
Position.
As a further solution of the present invention, the model LQ series continuous wall trench underground machine of the chute forming machine or
XG360。
As a further solution of the present invention, model DR-100, XY-1 or KT-22 of the rotary drilling rig.
In conclusion compared with the prior art, the invention has the following beneficial effects:
The present invention by chute forming machine grab bucket position apply perpendicular drilling so that grab bucket can along it is perpendicular drilling be more easier into
Enter harder ovum gravel erratic boulder stratum, accelerate the grooving speed of ground-connecting-wall, reduces chute forming machine abrasion, reduce particular formation ground-connecting-wall
Construction cost, meanwhile, perpendicular drilling can guide chute forming machine carry out grooving operation, reduce ground-connecting-wall invades limit.
The perpendicular drilling of brill is applied before grooving, chute forming machine grab bucket drills into stratum along perpendicular, can significantly reduce chute forming machine entrance
The difficulty on stratum, improves speed of application, reduces the abrasion of chute forming machine, and perpendicular drilling is capable of providing certain guiding function
Can, reduce grooving stage ground-connecting-wall invades limit, reduces the construction cost of ground-connecting-wall.
