Description
Technical field
The present invention relates to the Refloatation method of the employed grab bucket of a kind of continuous wall trench underground.
Background technology
Adopt the grab chute forming technology in the construction of diaphragm wall, be a kind of technology commonly used in present deep foundation ditch and the underground engineering construction.But in the construction, because the complexity of subsurface geology condition, as soft layers such as the layer of sand of easy landslide, mud matter, hard, closely knit iron plate layer of sand etc., and super dark ground-connecting-wall, all easily in the grab chute forming process, grab bucket is flowed or blow over and cover completely because of landslide or clipping is absorbed in the groove and can't proposes, cause the equipment loss, and need remodify quality accidents such as design.Construction party, owner are brought very big economic loss.
At present, had by the Refloatation method after burying grabbing bucket in the ground-connecting-wall construction:
1, in the grab bucket position of being buried, use high pressure slurry pump, the reverse circulating method of gaslift, with the native taking-up of the silt particle in the grab bucket on every side of flowing or blow over and cover completely, perhaps wash away grab bucket silt soil all around with deployed new mud liquid, reach the native effect of becoming flexible all around.This grab bucket is sling in groove with crane equipment reducing under the silt particle soil restraint condition.
2, when above-mentioned situation still can not reach requirement, under the safety prerequisite, by the diver with under the suspension hook to the grab bucket on the suspension centre position, crane and the groover master crane big by lifting capacity pull up grab bucket simultaneously.
3, on the next door, position of being flowed or blow over and cover completely grab bucket, the grooving and the same degree of depth strengthen the scope of freedom of being buried grab bucket again, adopt the 1st method simultaneously, and the earth around the cleaning grab bucket reduces clipping power, reaches with lifting appliance at last it is hung on.
Above-mentioned first method is flowed or blow over and cover completely not deeply in grab bucket, when silt particle was removed easily, fishing success ratio was higher, otherwise, just be difficult to realize.The 2nd kind of method, safety can not be surveyed, and simultaneously, needs to cooperate with the crane of big starting power, and expense height, risk are big.
The 3rd kind of method requires the accurate positioning of next door grooving, simultaneously, guarantee the stability of new grooving, prevents to cave in once more the difficulty that increases the weight of to salvage.So time is longer, and processing procedure requires high, and the expense height is dealt with easy failure improperly.
Summary of the invention
The object of the present invention is to provide the Refloatation method of a kind of simple, good reliability, the employed grab bucket of continuous wall trench underground that salvaging efficient is high.
