Embodiment Construction

[0019] In order to further explain the technical means and effects of the present invention to achieve the intended purpose of the invention, the specific implementation and working principle of the rapid soil extraction device under deep water conditions proposed by the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments. illustrate.

[0020] The present invention mainly includes: an air mud suction system, a rock breaking system, and a sealed box body 13 . The rock-breaking system includes: a rock-breaking mechanism, a power mechanism, an underwater cable, and a power supply mechanism. The rock-breaking mechanism is connected to the power mechanism, and the power mechanism is connected to the power supply mechanism through an underwater cable. The box is arranged on the mud suction system, and the rock-breaking mechanism connected with the power mechanism is outside the sealed box. For the rock-breaking...

Abstract

The invention relates to the technical field of desilting systems, and discloses a device for rapidly taking soil under a deep-water condition. The device comprises an air silt suction system, a rock breaking system and a sealed tank body, wherein the rock breaking system comprises a rock breaking mechanism, a power mechanism, a submerged cable and a power supply mechanism; the rock breaking mechanism is connected with the power mechanism; the power mechanism is connected with the power supply mechanism through the submerged cable, is arranged in the sealed tank body, and is arranged on the silt suction system through the sealed tank body; the rock breaking mechanism connected with the power mechanism is positioned outside the sealed tank body. The device is free of limitation of the water depth, and is adapted to various soils; in case of cement rocks, the rock breaking capability can be improved in a manner of adding a counterweight, and broken rocks are sucked into a silt discharging pipe, and are discharged out of an open caisson.

Description

technical field [0001] The invention relates to the technical field of dredging systems, and is mainly suitable for soil-borrowing operations under deep water conditions. Background technique [0002] The sinking of the caisson is mainly through taking soil evenly from the well hole by mechanical or manual methods, weakening the frontal resistance of the base to the blade foot and the frictional resistance between the well wall and the soil, so that the caisson relies on its own gravity to overcome the above resistance and sink. . [0003] Traditionally, there are two methods of underwater soil extraction: [0004] (1) hydraulic suction dredger. The composition of the hydraulic dredger includes: dredger, dredger pipe, mud pumping pipe and high-pressure water pipe. There is a high-pressure water nozzle inside the dredger, and the soil becomes mud sucked into the dredger pipe. After the sucked mud is mixed with high-pressure water The diluted mud flows out from the pipeline...
