Embodiment 1

[0037] Such as figure 1 As shown, the super large FRP combined storage tank structure with floating roof includes tank roof 1, tank wall, tank bottom 2, combined with Figure 12 As shown, the tank roof 1 adopts FRP (fiber reinforced plastic) reticulated shell structure, and the FRP board is laid on the FRP reticulated shell structure; the tank bottom 2 is an active powder concrete bottom plate; It is composed of active powder concrete in the middle, and the floating roof 9 is installed inside the tank wall; connecting pieces are arranged between the inner and outer FRP boards, such as Figure 5 As shown, the connector 5 is a fiberglass connector, and the two ends of the connector 5 are respectively connected with two layers of FRP boards inside and outside. Figure 7, Figure 8 As shown, concrete trapezoidal grooves 7 are sequentially arranged between the inner and outer layers of FRP slabs along the circumferential direction, and the prestressed tendons 8 are stretched in s...

Embodiment 2

[0046] Such as figure 2 As shown, the super-large FRP composite storage tank structure with floating roof includes tank roof 1, tank wall, and tank bottom 2. Two layers of FRP boards are sandwiched between active powder concrete, and the floating roof 9 is installed inside the tank wall; connecting pieces are arranged between the inner and outer layers of FRP boards, such as Image 6 As shown, the connectors 6 are arranged horizontally, and one end of some connectors is fixed on the outer FRP board 4, and one end of some connectors is fixed on the inner FRP board 3, and the two connectors are arranged alternately on the inner and outer sides. between two layers of FRP slabs; between the inner and outer layers of FRP slabs, concrete trapezoidal grooves 7 are sequentially arranged along the circumferential direction, and the prestressed tendons 8 are stretched in sections between two adjacent concrete trapezoidal grooves 7; the inner layer of FRP slabs 3 and the outer layer La...

Embodiment 3

[0054] Such as image 3 As shown, the super large FRP composite storage tank structure with floating roof includes tank roof 1, tank wall and tank bottom 2. The tank roof adopts FRP reticulated shell structure, and FRP plates are laid on the FRP reticulated shell structure; The active powder concrete is sandwiched between the layers of FRP boards, and the floating roof 9 is installed inside the tank wall; connecting pieces are arranged between the inner and outer FRP boards, and concrete trapezoidal grooves 7 and prestressed tendons 8 are arranged in sequence along the circumference between the inner and outer FRP boards Sectional stretching is between two adjacent concrete trapezoidal grooves 7; the inner layer FRP board 3 and the outer layer FRP board 4 are both formed by connecting FRP splicing boards through a tongue and a groove. The floating roof 9 is a self-floating hydrogen-filled floating roof. The hydrogen-filled floating roof is formed by a light FRP sheet, and its ...

Abstract

The invention relates to an extra-large fiber reinforced plastic (FRP) combined storage tank structure with a floating roof, and a construction method of the storage tank structure. The extra-large FRP combined storage tank structure comprises a tank top, a tank wall and a tank bottom, wherein the tank top has an FRP latticed shell structure; FRP plates are laid on the FRP latticed shell structure; the tank wall is composed of an inner layer FRP plate, an outer layer FRP plate and active powder concrete between the inner layer FRP plate and the outer layer FRP plate; the floating roof is arranged in the tank cover; a connection piece is arranged between the inner layer FRP plate and the outer layer FRP plate; concrete trapezoid grooves are sequentially formed between the inner layer FRP plate and the outer layer FRP plate along a circumferential direction; prestress bars are pulled between every two adjacent concrete trapezoid grooves section by section; and the inner layer FRP plate and the outer layer FRP plate are formed by connecting FRP spliced plates through tenon tongues and tenon grooves. The extra-large FRP combined storage tank structure is high in corrosion resistance and freezing resistance, insensitive to temperature change, low in heat transmission speed, favorable for keeping temperature in a tank body, high in compression strength, high in corrosion resistance and relatively high anti-permeability.

Description

1. Technical field: [0001] The invention relates to a storage tank in the field of civil and architectural structures, in particular to a super large FRP combined storage tank structure with a floating roof and a construction method thereof. 2. Background technology: [0002] With the rapid development of the global economy, the demand for oil is increasing day by day, and oil as a strategic energy reserve has become more and more important. Devices for storing petroleum or processed products (gasoline, diesel, engine oil, etc.) are essential oilfield equipment, and vertical circular storage tanks are widely used in major oilfields and chemical plants because of their large volume and easy storage. With the increase of processing volume, the volume requirements for temporary storage equipment are also increasing, and the conventional steel storage tanks in the past can no longer meet the needs of development well. Therefore, the research on ultra-large storage tanks has att...
