Abstract
The invention provides a protection method for a stainless steel combined casing pipe for a bridge cable, and belongs to the technical field of bridge cable protection. The method includes the steps that firstly, a trapezoidal stainless steel plate is obtained after being cut according to the size of the cable to be protected; secondly, corresponding meshed waveform teeth are pressed on the two waist sides of the stainless steel plate; thirdly, the stainless steel plate is coiled in the axis direction of the cable to be protected; fourthly, the waveform teeth of the stainless steel plate are meshed, and then the stainless steel plate forms a reducing casing pipe to cover the bridge cable; fifthly, the reducing casing pipe is fixed through a pipe clamp; sixthly, the third step, the fourth step and the fifth step are repeated, and the whole bridge cable is covered with the combined casing pipe formed by multiple sections of the reducing casing pipe in a large-small end-to-end mode; seventhly, weather-proof waterproof sealing is conducted on a longitudinal joint and a transverse joint of the combined casing pipe. The method has the advantages that water and steam are prevented from entering the cable, so that the bridge cable is prevented from being damaged.
Description
Technical field
What the present invention relates to is the method that the bridge cables such as a kind of suspension rod to main rope of suspension bridge, cable-stayed bridge cable, arch bridge protect.Belong to bridge cable guard technology field.
Background technology
Cable is generally used as in the bridge such as main rope of suspension bridge, stay cable of cable-stayed bridge.The protection of existing bridge cable conventionally adopts and on cable, curls zinc-coated wire, also pricks, then smears to protect with putty filleting, paint and unsaturated-resin by the close around the bundle of zinc-coated wire.This kind of protection method shortcoming: because putty filleting, paint and unsaturated-resin protection can not be durable, grown that space between the steel wire of cable has water, vapour enters the time, water causes zinc-plated corrosion, finally can cause cable impaired.
Summary of the invention
The object of the invention is to overcome the above-mentioned shortcoming of prior art, a kind of means of defence that with stainless steel assembled casing, bridge cable is carried out durability protection is provided.Its content is:
1., cut trapezoidal corrosion resistant plate according to the size of the cable of wish protection,
2., at waveform tooth corresponding to two waist limits compactings of trapezoidal corrosion resistant plate,
3., the corrosion resistant plate of upper step gained is intervolved to corrosion resistant plate with its waveform tooth along the cable axis direction of wish protection,
4., the waveform tooth of engagement corrosion resistant plate, make corrosion resistant plate form one large one small reducing casing tube and be coated on bridge cable outside,
5., above-mentioned reducing casing tube is fixed with pipe clamp,
6., repeating step 3., 4., 5., and section by section whole bridge cable is coated in the assembled casing being formed by some joint reducing casing tubes by large and small end to end mode,
7., the vertical, horizontal joint of assembled casing is carried out to weather-proof waterproof sealing.
The assembled casing that this method utilization is made up of some joint stainless steel reducing casing tubes is coated on whole bridge cable wherein; stainless steel assembled casing plays shielding of ultraviolet and delays the effect that interior protection coating materials is aging; avoid water, vapour to enter; make original putty filleting, paint and unsaturated-resin protection energy durable, make bridge cable avoid damaging thereby make internal corrosion protective layer structure obtain durability protection.Late maintaining can overhaul, it is simple and convenient to construct.
Below in conjunction with embodiment, the present invention will be further described.

Fig. 2 is the schematic diagram that intervolves of trapezoidal corrosion resistant plate
Fig. 3 is the assembled casing schematic diagram being coated on suspension cable suspension bridge cable
Detailed description of the invention
As shown in Figures 1 to 3, this method is made up of following steps:
1., cut trapezoidal corrosion resistant plate 2 according to the size of the bridge cable 7 of wish protection,
2., at waveform tooth 1 corresponding to two waist limits compactings of trapezoidal corrosion resistant plate,
3., the corrosion resistant plate of upper step gained is intervolved to corrosion resistant plate 2 with its waveform tooth along the axis direction of the bridge cable 7 of wish protection.Before intervolving, if necessary, can do the conventional interior protective treatments such as paraffin sealing to the bridge cable of wish protection, overcoat 4 in forming,
4., engagement corrosion resistant plate waveform tooth 1, make corrosion resistant plate form an one large one small reducing casing tube 6 be coated on bridge cable 7 outsides,
5., with pipe clamp 5, above-mentioned reducing casing tube 6 is fixing,
6., repeating step 3., 4., 5., and section by section whole bridge cable 7 is coated in the assembled casing being made up of some joint reducing casing tubes 6 by large and small end to end mode,
7., adopt the sealing of silicone weather resistant marine glue to complete the protection to bridge cable 7 to the vertical, horizontal joint of assembled casing.
For preventing flow backwards, can be by the merogenesis socket installation from low to high of stainless steel protection tube, the major part of sleeve pipe is downward, and socket length is advisable to be no less than 2cm.
