Detailed Description
The technical solution of the present invention is further described and illustrated by the following specific embodiments.
Example (b):
the utility model provides an underwater bored concrete pile dismantlement formula steel protects a section of thick bamboo, as shown in the figure, because present steel protects a section of thick bamboo and all is disposable, consequently, this application protects a section of thick bamboo with this steel and sets up to protect a section of thick bamboo 1 and subdivision formula steel and protects a section of thick bamboo 2 including integral steel, integral steel protects a section of thick bamboo 1 and is used for beating locate the riverbed mud face once, and subdivision formula steel protects a section of thick bamboo 2 and is used for dismantling so that the secondary use after integral steel protects a section of thick bamboo 1 and beats and establish and finish.
Therefore, the bottom of the split steel casing 2 is detachably connected with the top of the integral steel casing 1 into a whole, the split steel casing 2 is composed of two halves, including a first half casing 3 and a second half casing 4, and the first half casing 3 and the second half casing 4 are detachably combined into a whole; a plurality of matched positioning plates 5 are respectively arranged at the splicing parts of the first half protective barrel 3 and the second half protective barrel 4, a U-shaped bolt groove 6 with an upward opening is formed in each positioning plate 5, and the first half protective barrel 3 and the second half protective barrel 4 are fixed into a whole through a positioning bolt 7. The positioning plate 5 is used for positioning and splicing the two half protection cylinders together, and the positioning bolt 7 is used for locking the two half protection cylinders into a whole by being embedded into the bolt groove 6. And a water stop strip 13 is arranged at the joint seam of the first half protective barrel 3 and the second half protective barrel 4.
The bottom of the split steel casing 2 is detachably connected with the top of the integral steel casing 1 and is consistent with the connection mode of the two semi-steel casings.
After the detachable installation is realized, the steel casing can be detached in a simpler and more convenient manner, and therefore the split steel casing 2 is provided with the detaching steel wire rope 8, the detaching steel wire rope 8 is connected with each positioning bolt 7, and the positioning bolt 7 is detached by pulling the detaching steel wire rope 8 in the later period so as to detach the two semi-steel casings. Meanwhile, the bottom of the split steel protection cylinder 2 and the top of the integral steel protection cylinder 1 are detachably connected and are consistent with the connection mode of the two semi-steel protection cylinders, and the split steel protection cylinder 2 and the integral steel protection cylinder 1 can be detached by detaching the steel wire rope 8. Therefore, the launching risk caused by manual close-distance disassembly can be saved, and the problem of cost improvement is solved.
The specific way of disassembling the steel wire rope 8 is as follows: dismantle and be equipped with chuck 9 on the wire rope 8, dismantle wire rope 8 and pass by positioning bolt 7's inboard in proper order to it is fixed with each positioning bolt 7 through chuck 9, make like this dismantle wire rope 8 with the split type steel protect section of thick bamboo 2 on positioning bolt 7 from top to bottom concatenate as an organic whole, only need the pulling dismantle wire rope 8, just can pull out the positioning bolt who establishes ties on dismantling wire rope 8 from the U-shaped groove one by one.
Every locating plate 5 all is equipped with reinforcing plate 10 behind one's back to strengthen the setting to locating plate 5, improve the steel and protect a result stability of section of thick bamboo, protect a section of thick bamboo 3 and the second is half at first half and all be equipped with curved horizontal reinforcing ring 11 on protecting a section of thick bamboo 4, first half protects a section of thick bamboo 3 and the second is half and all is equipped with vertical strengthening rib 12.
