The specific embodiment
Below in conjunction with embodiment and contrast accompanying drawing the utility model is described in further detail.
Embodiment 1:
The utility model comprises that stand 1, chassis 2, hoisting system 3, tup 4, pullover wire rope 5, outer tube 6, hangers 7, tube drawing wire rope 8, interior pipe 9, pallet card 10 alive, reinforcing cage insertion electromagnetic shaker 11, guide rail 12, shake can pass bar 13, interior pipe 9 flexibly connects and is linked in the outer tube 6 of downward insertion underground with pallet card 10 alive, and the length of interior pipe 9 and diameter all length and the diameter than outer tube 6 are little, interior pipe 9 flexibly connects by pullover wire rope 5 with tup 4, and interior pipe 9 can move up and down with tup 4 in outer tube 6; Stand 1 is fixed on the chassis 2, and guide rail 12 is fixedly mounted on the outer side edges of stand 1, and reinforcing cage inserts electromagnetic shaker 11 and is placed on the guide rail 12, and shake can pass bar 13 goes into electromagnetic shaker 11 bolts with slotting reinforcing cage and be connected, and shake can pass bar 13 and closely contact with reinforcing cage 14 lower ends.
Tube drawing wire rope 8 one ends are connected with hoisting system 3, the other end is connected with the hangers 7 of outer tube lateral margin, promote outer tube 6.
In the construction, through the high hammer of tup 4 dredge hit and hang down that hammer is close and hit in pipe 9, obtain the full pound type stake, except enlarged footing 16 is formed on the bottom, the diameter of section of pile body 15 also obtains expansion, or the middle and lower part forms a plurality of enlarged footings 17; After pile body 15 forms, lay immediately that reinforcing cage inserts electromagnetic shaker 11 and shake can pass bar 13, reinforcing cage 14 is seated to the designing requirement absolute altitude, and then rise while shaking and to stir shake and can pass bar 13.
The full pound type bull bottom-enlarging filling pile of so finishing, strengthened in the following aspects:
