Problems solved by technology

[0004] 1. During the laying, coating and curing process of glass fiber and epoxy resin in the tank, a large number of bubbles will be generated, and it is not easy to be found and solved, so that the final formed rigid glass fiber inner tank can block and prevent oil seepage Leakage performance cannot be guaranteed
[0005] 2. The process is relatively complicated. It is necessary to coat the next layer of glass fiber after the previous layer is cured. The stacking operation prolongs the construction time. It is estimated that an oil tank of a regulated size will be operated according to the existing non-excavation transformation method The time is generally 20 days, so the work efficiency is low, and the safety problems of the personal and the environment of the construction are greatly increased virtually.
[0006] 3. Due to the large amount of toxic, explosive and volatile solvents used in construction, personnel work in a relatively closed space, and long-term direct contact with solvent volatiles has a great adverse effect on health

Embodiment 2

[0103] The difference between this embodiment and the foregoing embodiment mainly lies in:

[0104] Step 101 of this embodiment specifically includes:

[0105] In the form of a small-sized releasable prefabricated sheet 300, the side of the first releasable prefabricated sheet constituting the glass fiber reinforced layer 22 that is not covered with the first release member is covered on the tank through the prefabricated adhesive layer 1 On the inner surface of the body 3, after separating the first release part, the side of the second release prefabricated sheet constituting the skeleton penetration layer 21 that is not covered with the second release part is passed through in the form of a small-sized releasable prefabricated sheet The prefabricated adhesive layer 1 is covered on the other side of the glass fiber reinforced layer 22, or, the second releasable prefabricated sheet constituting the skeleton penetrating layer 21 is formed in the form of a small-sized releasable...

Embodiment 3

[0108] The difference between this embodiment and the foregoing embodiment mainly lies in:

[0109] The composite reinforcement layer 2 also includes: a grid cloth reinforcement layer 23 covered on the inner surface of the tank body 3 through the prefabricated adhesive layer 1 in the form of a detachable prefabricated part, and the mesh cloth reinforcement layer 23 is passed through the prefabricated adhesive layer. 1 Bonded with the glass fiber reinforced layer 22 or the skeleton penetrating layer 21, such as Figure 12 shown.

[0110] Then, the corresponding step 101 specifically includes:

[0111] In the form of a small-sized releasable prefabricated sheet 300, the side of the third releasable prefabricated sheet that constitutes the grid cloth reinforcement layer 23 that is not covered with the third release member is covered by a prefabricated adhesive layer 1 on the On the inner surface of the tank body 3, after the third release part is separated, the uncoated first r...

Abstract

The application of the invention discloses a non-excavation type reforming method of an oil tank. The non-excavation type reforming method comprises the following steps of covering a composite reinforcing layer on the inner surface of a tank body of the oil tank through bonding glue layers in the form of a separable type fabricated part, and covering an oil-gas obstructing composite film layer on one side, opposite to the tank body, of the composite reinforcing layer through the bonding glue layers in the form of a fabricated part. In this way, existing single-layer tanks are quite convenient to reform into double-layer tanks with excellent properties; requirements for high whole strength of the oil tank can be met; barrier properties to oil and gas are improved; working procedures are simplified, the construction difficulty is reduced, the construction time is shortened, and the working efficiency is improved; more importantly, a construction method that materials and adhesives are all prefabricated outside the tank is adopted, so that in-tank construction with zero solvents is completely realized, occupational injury to construction staff caused by the condition that the construction staff are in contact with conventional solvent type materials for a long time can be avoided, and the construction safety and the environment safety are greatly improved.

Description

technical field [0001] The present application relates to the technical field of oil tank reconstruction, in particular to a method for non-excavation reconstruction of an oil tank. Background technique [0002] At present, there are usually two methods for the transformation of oil tanks. One is the excavation transformation method, that is, after the oil tank is taken out from the ground, the oil tank is repaired, transformed, or a new oil tank is made, and then the processed oil tank is removed. The tank is buried in the ground, which is not only time-consuming and labor-intensive, but also has a complicated process and great environmental damage. The second is the non-excavation transformation method, that is, the buried oil tank is directly transformed without taking the oil tank out of the ground. Compared with the excavation transformation method, it saves time and effort, and the process is simplified and the labor intensity is relatively small . [0003] A main co...
