The invention provides a seabed suction type gravity anchor and a construction method thereof. The seabed suction type gravity anchor comprises an anchor body, a balance weight cabin, a negative pressure connecting cabin and a bottom suction cabin. The counterweight cabin is formed in the middle of the anchor body; the negative pressure connecting cabin is formed on the outer side of the counterweight cabin of the anchor body; the top ends of the negative pressure connecting cabins extend to the top surface of the anchor body and are respectively connected with a negative pressure water pumping device connecting port in a sealing manner; the bottom ends of the negative pressure connecting cabins extend to the bottom surface of the anchor body and are respectively connected with the bottom suction cabins in a sealing manner; the top of the counterweight cabin is opened and is provided with a top cover plate; the top cover plate is detachably connected with the anchor body and covers the counterweight cabin; and an anchor chain connecting hole is formed in the center of the top surface of the top cover plate. According to the seabed suction type gravity anchor and the construction method thereof, the problem that a common gravity anchor can only make contact with gravel or soft soil on the surface of the seabed after sinking into the seabed and cannot penetrate into the soil to guarantee enough lateral bearing capacity is solved.

    本发明提供一种海底吸力式重力锚及其施工方法,包括锚体、配重舱、负压连接舱和底部吸力舱;所述锚体中部形成所述配重舱;所述锚体的所述配重舱的外侧形成所述负压连接舱;所述负压连接舱的顶端延伸至所述锚体的顶面并分别密封连接一负压抽水装置连接口;所述负压连接舱的底端延伸至所述锚体的底面并分别密封连接一所述底部吸力舱;所述配重舱的顶部开口并设置有一顶部盖板;所述顶部盖板与所述锚体可拆卸连接并遮盖所述配重舱;所述顶部盖板的顶面中心位置设置有一锚链连接孔。本发明的一种海底吸力式重力锚及其施工方法,解决一般的重力锚沉入海底后仅能与海底表面沙砾或松软土体相接触,无法深入土体内部保证足够的侧向承载力的问题。
