The invention provides a method for repairing a marine vessel floating block, which comprises the following steps:
s1, cleaning the section 1 of the marine vessel floating block;
after the marine pipe floating block is broken, the problems of pollution, material aging, unevenness of the section 1 and the like often exist in the section 1, and before the marine pipe floating block is repaired, the section 1 needs to be polished to remove the polluted, damaged and aged buoyancy materials. Dust or other substances that affect the adhesion of the adhesive may remain on the section 1 after grinding. Thus, the polished section 1 can be cleaned by gas purging and/or chemical cleaning.
S2, adhering the cleaned section 1;
after the section 1 is cleaned, the section 1 needs to be bonded by an adhesive 4. Before bonding, uniformly coating an adhesive 4 on the cleaned section 1, wherein any material with good bonding performance with the floating block material can be selected as the adhesive 4. Among them, the adhesive using epoxy resin as a base has advantages of good adhesiveness, low cost, and the like, and is an ideal 4 kinds of adhesive. In addition, the composite foam material taking the epoxy resin as the matrix is an adhesive material newly developed in recent years, the basic components of the composite foam material are the epoxy resin, a curing agent, hollow glass beads and the like, and the composite foam material taking the epoxy resin as the matrix has the advantages of good mechanical property, acid and alkali resistance, easiness in forming and the like, and is an ideal material for bonding the floating blocks of the marine pipe.
The edges of the floating blocks of the marine pipe are aligned in the bonding process, and the two sections 1 are folded, so that the sections 1 are bonded together under the action of the adhesive 4. In order to avoid the situation that the floating block of the marine pipe needs to be fixed when moving in the bonding process, the floating block of the marine pipe can be installed and clamped by a bench or special fixing equipment when necessary, and the bonding of the floating block of the marine pipe is completed after the adhesive 4 is cured. In addition, hot air may be used to blow the broken portion to accelerate curing of the adhesive 4.
S3, arranging an installation groove 2 which penetrates through the section 1 and is used for installing the reinforcing rib 3 on the surface of the marine pipe floating block;
the repaired marine pipe floating block still can be subjected to the action of bending load, and for improving the bending strength of the marine pipe floating block, the reinforcing ribs 3 can be arranged on the surface of the marine pipe floating block after the marine pipe floating block is bonded, and when the marine pipe floating block is subjected to the bending load, the reinforcing ribs 3 resist the bending load through tensile deformation, so that the bending strength of the marine pipe floating block is improved.
Optionally, an installation groove 2 may be formed in the surface of the marine pipe floating block, and then the reinforcing rib 3 is fixed in the installation groove 2 to realize the arrangement of the reinforcing rib 3. As shown in fig. 3, at least two installation grooves 2 may be formed on one side surface of the marine vessel slider. The breakage of the marine pipe slider is usually the location where its stress is concentrated or there is a defect, so the installation groove 2 is located through the section 1 of the marine pipe slider, so that the direction of the reinforcing bars 3 is parallel to the direction of the bending load. Specifically, the diameter, number, length and position distribution of the reinforcing ribs 3 required to be arranged on the surface of one side of the marine pipe floating block can be obtained through mechanical calculation according to the mechanical characteristics of the marine pipe floating block material, the reinforcing rib 3 material and the adhesive 4 material, and are not repeated herein. The depth of the mounting groove 2 is more than or equal to 2 times of the diameter of the reinforcing rib 3, the length of the mounting groove 2 is not less than the length of the reinforcing rib 3, and the width of the mounting groove 2 is not less than the diameter of the reinforcing rib 3.
S4, installing the reinforcing ribs 3 in the installation grooves 2;
when installing the reinforcing bars 3, the bottom of the installation channel 2 is first pre-filled with adhesive 4, the thickness of the pre-filled adhesive 4 being generally no greater than 1/3 of the depth of the installation channel 2. Subsequently put into mounting groove 2 with strengthening rib 3 to press down strengthening rib 3 and make its bottom that is close to mounting groove 2, and the adhesive 4 of pre-filling overflows to the position that is higher than strengthening rib 3 axis through the extrusion, and then remains the bubble in mounting groove 2 when avoiding installing strengthening rib 3, packs adhesive 4 in the remaining space of mounting groove 2 afterwards, and then seals strengthening rib 3 in mounting groove 2 completely. After the reinforcing ribs 3 are installed, the adhesive 4 needs to be cured, and in order to accelerate the curing speed of the adhesive 4, the installation groove 2 can be blown by hot air.
In order to further improve the bending strength of the marine pipe floating block, after the reinforcing ribs 3 are installed in the installation groove 2, repair fibers can be arranged on the surface of the installation groove 2, and then the surface of the marine pipe floating block is reinforced. The method comprises the following specific steps: the reinforcing fibers are cut according to the shape and size of the mounting groove, and then are soaked in the adhesive, specifically, glass fibers can be used as the reinforcing fibers, and certainly, a user can also use Kevlar fibers or carbon fibers and the like as the reinforcing fibers according to needs. The glass fiber may be chopped strand mat, woven cloth, chopped strand fiber, etc. The main purpose of the infiltration process is to fill the pores in the reinforcing fibers with an adhesive to facilitate the adhesion of the reinforcing fibers to the surface of the sea-pipe floes. After infiltration, the reinforcing fibers are laid on the surface of the mounting groove, and the purpose of reinforcing the fracture part is achieved. And after the adhesive is cured, the fixing of the reinforcing fibers and the floating blocks of the marine pipe can be finished.
And S5, overturning the marine pipe floating block, and repeating the step of forming the mounting groove 2 penetrating through the section 1 on the surface of the marine pipe floating block.
As shown in fig. 3, the surface of the inner side and the surface of the outer side of the marine pipe floating block are generally required to be provided with the reinforcing ribs 3 and the reinforcing fibers, so that the surface of one side is required to be provided with the reinforcing ribs 3 and the reinforcing fibers, and the specific steps can be referred to above and are not described herein again.
In this embodiment, after the bonding of the section 1 of the marine pipe floating block is completed, the reinforcing ribs 3 are embedded in the surface of the marine pipe floating block, and the reinforcing fibers are laid in the mounting groove 2, so that the mechanical structure of the marine pipe floating block is reinforced. When the marine pipe floating block bears bending load, the reinforcing ribs 3 and the reinforcing fibers can improve the bending strength of the marine pipe floating block, secondary fracture of the marine pipe floating block is avoided, the quality and stability of repair work are improved, and the service life of the marine pipe floating block is prolonged.
