Embodiment Construction

[0048] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0049] The embodiment of the present invention provides a kind of original soil backfill device, such as Picture 1-1 As shown, the original soil backfilling device includes: a main frame 00 and a direction guiding mechanism 10 , a soil scraping mechanism 20 and a supporting mechanism 30 arranged on the main frame.

[0050] Wherein, the direction guiding mechanism 10 is used to guide the raw soil backfilling device to travel along a preset route according to the width and slope of the trench.

[0051] The soil scraping mechanism 20 is used for scraping the surface soil of the seabed into the trench.

[0052] The support mechanism 30 is used to support the original soil backfill device on the seabed according to the width of the trench....

Abstract

The invention discloses a raw soil backfill device, and belongs to the ocean machinery technical field; the raw soil backfill device comprises a main body frame, and a direction guiding mechanism, a soil scraping mechanism, a support mechanism and an anode block arranged on the main body frame; the direction guiding mechanism is used for guiding the raw soil backfill device to forward along a preset route according the width and slope of a pipe ditch; the soil scraping mechanism is used for scraping the surface layer soil on the seabed into the pipe ditch; the support mechanism is used for supporting the raw soil backfill device on the seabed according to the width of the pipe ditch. An existing raw soil backfill device is poor in versatility; the raw soil backfill device can solve said problem, and is used for raw soil backfill works.

Description

technical field [0001] The invention relates to the technical field of marine machinery, in particular to an original soil backfilling device. Background technique [0002] A submarine pipeline is a closed pipeline that continuously transports a large amount of oil, gas and water on the seabed. In offshore oil development projects, in order to ensure the safe operation of submarine pipelines, it is necessary to carry out trenching operations to form trenches in order to lay submarine pipelines in the trenches, and then carry out the original soil backfill operation, that is, the raw materials generated by trenching operations Soil (that is, the surface soil of the seabed near the trench) is backfilled into the trench. [0003] There is a kind of raw soil backfilling device in the prior art, and the raw soil backfilling device is used in conjunction with a trenching device for trenching operations. The trenching device is used to dig out a "V"-shaped pipe trench. After the ...
