Description
Technical field
The present invention relates to a kind of perfusion restorative procedure, specifically, relate to a kind of perfusion restorative procedure of underwater complex structure.
Background technique
Submerged structure is because of corrosion attenuate, or is subject to external force deformation, breakage, can not reach former design mechanical strength, need to do and strengthen repairing.Existing generally employing, first at land prefabricated metal anchor ear, is then installed under water, and finally in the gap of anchor ear and structure, cement injection or high performance macromolecular material are strengthened repairing.It exists following not enough: 1, submerged structure is owing to being corroded or outside destroy, and actual anchor ear size can not be calculated by original structure drawing, needs actual measurement under water, has increased the workload of repairing.2, because adopting Plate Steel, makes metal anchor ear, for labyrinth, such as: tube furcation connecting part repair anchor ear used prefabricated just require accurate especially, careless slightly being difficult to is in place, so anchor ear is prefabricated, require high, cost to be difficult to control, and it is many that anchor ear uncertain factor is installed under water, construction risk is large.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of perfusion restorative procedure of underwater complex structure is provided.
To achieve these goals, the present invention adopts following technological scheme:
The present invention adopts extension spring in area to be repaired, be wound around and fix, and then with take-up strap under water, is wound around, and at body structure surface, a flexible anchor ear is made at scene, then macromolecular material under priming petock in the gap of spring.Concrete steps are as follows:
A perfusion restorative procedure for underwater complex structure, comprises the steps:
(1) first removing surface is carried out in area to be repaired, remove surperficial marine growth, pollutant, floating rust, the metal of body structure surface or original coating are carried out to surface treatment;
(2) to leaking or damaged place carries out shutoff or reparation with scribbling the steel plate of repairing glue under water;
(3) with extension spring, be wound around surface, area to be repaired, spring winding spacing is not more than 1.5 times of spring outer diameter, and the head of extension spring is pressed in adjacent spring fixing, and afterbody embeds and is connected with another coil spring head;
(4) after stretching has been wound around, with reinforcing band under water, from bottom, be wound around, perfusing hole is installed at its bottom, top and other position in the process being wound around and is fastened with reinforcing band under water, reinforcing band is wound around and will overlaps winding under water, can not there be leak source at winding zone bottom and middle part, prevent the leakage in filling process;
(5) after reinforcing band is under water dry, open all perfusing hole ball valves, by high-voltage tube, to macromolecular material under priming petock in the gap of extension spring, from the upwards perfusion of a minimum perfusing hole, when having material to overflow from perfusing hole ball valve, close this ball valve;
(6), when having material to overflow, stop perfusion from the perfusing hole ball valve of the topmost part;
(7) complete perfusion, cleaning equipment and pipeline can come into operation after material cured.
In above-mentioned perfusion restorative procedure, the described surface treatment of step (1) refers to grinding process, process grade reach St1.0 level or more than.
In above-mentioned perfusion restorative procedure, the described perfusing hole of step (4) is comprised of end steel plate and the ball valve that is arranged on end steel plate, and perfusing hole is installed one every 30cm.
In above-mentioned perfusion restorative procedure, the external diameter of described extension spring is design perfusion thickness, and scope is between 5-15mm.
In above-mentioned perfusion restorative procedure, the diameter of described extension spring silk is between 0.5-1.0mm, curls up ratio: 5-12, and the back pitch that stretches in winding process is controlled between 2-6mm.
In above-mentioned perfusion restorative procedure, described extension spring is cross winding also, increases stationarity.
In above-mentioned perfusion restorative procedure, described reinforcing band is under water a kind of in the glass fiber cloth that infiltrates of wet-solidifying single-component polyurethane, carbon fibre cloth, aryl fiber cloth.
In above-mentioned perfusion restorative procedure, described macromolecular material is under water preferably receives a kind of in plastic-steel NPS1101, NPS1102, NPS1103, NPS1121.
In above-mentioned perfusion restorative procedure, the described glue of repairing is under water preferably epoxy resin underwater repair glue, and the trade mark is for receiving plastic-steel NPS8210.
Compared with prior art, the present invention has following beneficial effect:
1. the present invention by being directly wound around extension spring in structure to be repaired, reinforcing band under winding water again, with the anchor ear of the method field fabrication, can be fitted in closely body structure surface, solved and repaired that the required steel anchor ear of labyrinth is difficult to make and the large problem of installation difficulty under water in the past;
2. perfusion thickness of the present invention is determined by extension spring external diameter, between spring, can mutually embed connection, has guaranteed the even of perfusion reparation thickness.And steel anchor ear perfusion thickness is limited by: limit thick code thickness and mounting point, anchor ear to manufacture and design the pretightening force factors that precision, anchor ear are installed accurate degree, bolt, because uncontrollable factor is many, perfusion area thickness is difficult to accomplish evenly;
3. extension spring final sum pouring material is combined with each other and has formed the composite organic-inorganic material that metal strengthens, and has strengthened perfusion repairing effect;
This flexible anchor ear by extension spring and under water reinforcing band form, less than steel anchor ear weight, alleviated the load of structure.
