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 trachoma and pinholes will be produced, which are not easy to be found and solved, resulting in the final rigid glass fiber inner tank being resistant to oil. There are hidden defects in the barrier and anti-leakage performance
[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 layered operation prolongs the construction time. It is estimated that a 30m 3 According to the existing non-excavation transformation method, the operation time of large and small oil tanks is generally 16 to 20 days, and the work efficiency is relatively low. Long-term construction in an atmosphere containing a large amount of benzene also leads to serious occupational injuries and a large number of environmental hazards. Pollution
[0006] 3. The task of safety management is arduous. Due to the large amount of toxic, explosive and volatile solvents used in the construction, personnel work in a confined space, and a little carelessness may cause personal injury or death accidents

Embodiment 1

[0041] This embodiment provides a method for non-excavation transformation of oil tanks, which can mainly carry out non-excavation transformation of buried oil tanks. The method mainly includes: figure 1 The flow shown:

[0042] 101, the composite reinforcement layer 2 is covered on the inner surface of the oil tank body 3 through the adhesive layer 1 in the form of a prefabricated part. The composite reinforcement layer 2 includes: a skeleton penetrating layer 21, and glass covered on the skeleton penetrating layer 21 The fiber-reinforced layer 22, the frame penetration layer 21 includes: a frame 211 and a through cavity 212 between the frames 211 for placing oil and gas leakage detection components, such as figure 2 The non-excavation transformation structure of the oil tank is shown;

[0043] Specifically, the adhesive layer 1 is made of epoxy resin glue, and the prefabricated part can be a small-sized prefabricated sheet or a large-sized prefabricated sheet. The skeleton...

Embodiment 2

[0058] The difference between this embodiment and other embodiments mainly lies in:

[0059] Step 101 of this embodiment is specifically: splicing small-sized prefabricated sheets 300 to form the skeleton penetrating layer 21 and the glass fiber reinforced layer 22, including: splicing along the direction parallel to the axial direction of the tank body 3, and 3 Splicing in the circumferential direction. When the tank body 3 is a regular cylindrical tank body, the size of the small-sized prefabricated sheet 300 meets the following requirements: the size in the length direction is usually smaller than the length of the tank body 3 in the axial direction, and the size in the width direction is also smaller than that of the tank body 3 in the axial direction. less than the perimeter of the tank body 3 in the circumferential direction, such as Figure 11 shown.

Embodiment 3

[0061] The difference between this embodiment and other embodiments mainly lies in:

[0062] In this embodiment, the glass fiber reinforced layer 22 is located on one or both sides of the skeleton 211, and the glass fiber reinforced layer 22 can be made of glass fiber woven cloth soaked with epoxy resin glue or glass short fiber reinforced TPU instead of the skeleton through The panel and / or bottom plate of the layer 21, the unit structure formed by the combination of the skeleton penetrating layer 21 and the glass fiber reinforced layer 22 is combined through the splicing groove 213,

[0063] Then the corresponding step 101 is specifically:

[0064] Splicing in the form of small-sized prefabricated sheets 300 to form the composite reinforcement layer 2 includes: splicing along the direction parallel to the axial direction of the tank body 3, and splicing along the circumferential direction of the tank body 3, or prefabricated in a large size The sheets 100 are spliced ​​to f...

Abstract

The invention discloses a non-excavation modifying structure for an oil tank. The non-excavation modifying structure comprises a tank body, a composite reinforcing layer and an oil-gas obstructing composite membrane, wherein the composite reinforcing layer covers the inner surface of the tank body in a prefabricated member manner, and the oil-gas obstructing composite membrane covers one side, opposite to the tank body, of the composite reinforcing layer in a prefabricated member manner; the composite reinforcing layer comprises a framework penetration layer and a glass fiber reinforcing layer which covers the framework penetration layer, the framework penetration layer comprises frameworks and penetration cavities, and the penetration cavities are formed among the penetration cavities and are used for placing leak detection elements. Therefore, an existing single-layer tank can be very conveniently modified into a double-layer tank with excellent performance, so that the relatively high integral strength requirement of the oil tank is met, the oil-gas obstructing performance is improved, the working procedure is simplified, the construction time is shortened, and the working efficiency is improved; and besides, the occupational injury caused by long-term contact with traditional solvent materials to constructors is avoided, and the construction safety is greatly improved.

Description

technical field [0001] The present application relates to the technical field of oil tank transformation, in particular to a non-excavation transformation structure 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 and transformed, and then the treated oil tank is buried in the ground. It is not only time-consuming and labor-intensive, but also complicated and labor-intensive. 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 processing procedure of the existing non-excavation transformation method is: ...
