| titleOfInvention | A kind of super-large diameter that is applicable to revolves the pick cylinder brill digging pile driving construction |
| abstract | The utility model relates to spiral-digging pore filling pile construction technical field, be specifically related to a kind of super-large diameter that is applicable to and revolve the pick cylinder brill digging pile driving construction, comprise drilling pipe, a pick at the bottom of being provided with tin along barrel circumference bottom described drilling pipe, described drilling pipe top is provided with notched top steel plate, described top steel plate bottom surface is connected with reinforcement steel plate, and described reinforcement steel plate is provided with pick in cylinder.By the pick arranged with drilling pipe inside bottom drilling pipe, and the entrance angle of pick at the bottom of reasonable Arrangement cylinder, top rake and pick spacing, during construction the contact of pick at the bottom of cylinder and rock stratum in order, can be larger to the destroyed area of scar, in conjunction with the effect of pick in cylinder, this pick cylinder is bored and can not only destroy drilling pipe bottom perimeter rock stratum, can also after obtaining the scope of freedom, border, cylinder inner peripheral rock stratum is destroyed by pick in cylinder, rock stratum can be pulverized as far as possible, pick cylinder is made to bore the degree of depth that can dig down darker, reduce and mention the number of times that cylinder bores cleaning rock slag, improve to revolve and dig efficiency. |
