Abstract

The invention discloses a freely shaped reinforcing bar. The freely shaped reinforcing bar comprises a wrapping layer, wherein the wrapping layer comprises a composite material prepreg cloth layer anda thermosetting adhesive layer arranged on the prepreg cloth layer in a covered mode. The wrapping layer is wound for multiple layers from inside to outside to form a flexible cylinder of a certain length, and the flexible cylinder is provided with a hollow containing cavity formed in the extension direction of the flexible cylinder. An elastic supporting part is arranged in the hollow containingcavity in accordance with the extension direction of the flexible cylinder. The freely shaped reinforcing bar has the characteristics of free combination and flexible shaping. Through the reinforcingbar, a rigid supporting part is formed after solidification, and the advantages of good stiffness performance, high tensile strength, long service life and good sealing performance are achieved. In the process of trenchless renovation of buried oil tanks used for fuel oil, the continuous deformation of the oil tanks can be effectively prevented by installing the freely shaped reinforcing bars onthe buried oil tanks, the construction safety can be guaranteed, and the service life of the buried oil tanks can be prolonged.

Description

technical field [0001] The invention relates to the field of reconstruction of buried oil tanks, in particular to a free-formed reinforcing rib. Background technique [0002] In the long-term use of buried oil tanks, the following problems will occur: first, the tank wall is corroded; second, the external pressure causes the oil tank to deform. Regarding the first question, the corrosion mechanism is as follows: (1) The gas phase part of the oil tank is mainly chemically corroded, and the gas phase part is basically uniformly corroded. The corrosive atmosphere such as moisture, oxygen, carbon dioxide, and sulfur dioxide entering the tank condenses into an acidic solution on the tank, resulting in chemical corrosion. (2) The corrosion rate of the oil storage part of the oil tank is low, and generally does not cause special danger. However, it should be pointed out that the junction of the gas phase and the liquid phase, that is, the humid and oxygen-rich environment at the ...
