Description
Technical field
The present invention relates to underwater piles to remove field, in particular to welding cuts off construction method in reinforced concrete pile water
And its appurtenance.
Background technique
Bridge etc. is removed after reaching design service life, is removed difficult point and is underwater concrete pile.
Now, it removes underwater metal structure and reinforced concrete structure mainly uses subsea cutting technology, it is currently used
Aerobic-flammable lancing of subsea cutting technology, underwater oxygen-arc cutting, metal-electric arc cutting, submarine mechanical cutting, water jet are cut
It cuts, underwater plasma cutting, blast cutting etc..
Publication No. CN105064225A discloses welding excision construction work in a kind of old bridge reinforced concrete pile water
Method, comprising the following steps: (one) riverbed soil layer at pier location is rinsed using high pressure water flow, reduce riverbed surface elevation；(2) it is marking
Positioning, which is set, to be cut pile foundation cover to reinforcement and makes reinforcing steel bars exposed；(3) welding and cutting device cuts off reinforcing bar under water；(4) stake top applies horizontal
Pile body concrete at power laser cutting removes the pile body of separation；(5) filling pit slot, leveling riverbed.
Above-mentioned steps are the general operation process of welding excision, and welding process mainly passes through diving personnel's dive and carries out, but
In some waters, since water is more muddy, underwater visibility is low, therefore its construction is relatively difficult.
Summary of the invention
In view of the deficienciess of the prior art, the first object of the present invention is welding in a kind of reinforced concrete pile water
Construction method appurtenance is cut off, construction personnel is suitble to construct in muddy waters.
Above-mentioned technical purpose of the invention, which has the technical scheme that in reinforced concrete pile water, welds
Cut off except construction method appurtenance, the sealing film including floating ring and sinking ring in upper floating ring, sinking ring, connection, it is described on
Floating ring is spliced by least two floating bodies, and the sinking ring is at least spliced by two heavy bodies, the quantity of floating body and heavy body
Identical and upper and lower correspondence, sealing film include the membrane body for connecting corresponding floating body and heavy body, and adjacent membrane body is connected by waterproof slide fastener.
When muddy waters carries out welding operation, floating platform is first installed in water, floating platform is located at reinforcing bar to be cut
By concrete pile；Mounting auxiliary later, by upper floating ring, sinking ring splice sleeve outside reinforced concrete pile to be cut,
And membrane body is connected and to form sealing film, sinking ring submerged to sinking ring is abutted into the bottom, in sealing film and reinforcing bar to be cut
Flocculant is put into the operating space that concrete-pile column is formed, construction personnel slips into operating space and operates later.This programme
