Embodiment Construction

[0032] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the present invention will now be described with reference to the accompanying drawings.

[0033] Such as Figure 6 and Figure 7 As shown, the assembled cofferdam for emergency treatment of wetland oil pipeline leakage according to the embodiment of the present invention includes: a plurality of connected cofferdam units 20;

[0034] Such as figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 As shown, each cofferdam unit 20 includes:

[0035] The main board 4 is a steel plate, such as a straight plate, and the shape can be a rectangle;

[0036] The air box 5 is connected to the main board 4. The air box is, for example, a rectangular box. The air box has a hollow cavity to play a role of floating, and the main board 5 extends out of the air box 4. The air box 5 Eliminate the elastic deformation of the main board, and at the same time enable ...

Abstract

The invention provides an assembled cofferdam for leakage emergency treatment of an oil pipeline in a wet land. The assembled cofferdam for leakage emergency treatment of the oil pipeline in the wet land comprises multiple connected cofferdam units. Each cofferdam unit comprises a main board, an air box, a connecting pipe and an opening connecting part, wherein the air box is connected with the main board, the air box is provided with a cavity, and the main board extends out of the air box; the connecting pipe is located outside the air box and connected to the first end of the main board; and the opening connecting part is located outside the air box and connected to the second end of the main board. The adjacent cofferdam units comprise the first cofferdam unit and the second cofferdam unit and the connecting pipe of the first cofferdam unit is connected to the opening connecting part of the second cofferdam unit in a sealed manner. By the adoption of the assembled cofferdam, a leakage accident treatment mode is changed, accident treatment time is saved, accident treatment cost is reduced, the wet land environment damage degree is decreased, cost is low, and the environment-friendly effect is good.

Description

technical field [0001] The invention relates to a device for emergency treatment of wetland oil pipeline leakage accidents in the process of oil exploitation, in particular to an assembled cofferdam for emergency treatment of wetland oil pipeline leakage. Background technique [0002] Weitian Wetland is in spring, summer and autumn, and the water depth is about 1 meter. It is located in the oil field in Weitian Wetland, and the oil pipelines are buried underground in Weitian Wetland. These oil pipelines sometimes have pipeline perforation leakage accidents. In the event of a leakage accident, emergency treatment, control of the contaminated surface, and leakage repair are required. When processing, the following processes should be carried out at the leak point: cofferdam→pumping→digging→filling→backfilling→clearing the sore surface→restoring the ecology. At present, the cofferdam uses soil pile technology; The piles are filled with soil in woven bags to form an earth weir....
