Abstract

The invention discloses quick underwater soil extraction construction equipment comprising N dredging devices arranged in a ring shape, and a sludge suction device; each dredging device comprises a motor of which an output shaft is provided with a drill bit vertically downwards, and a plurality of reamers distributed around the drill bit in the ring shape; the sludge suction device is located in the center of the ring shape formed by the N dredging devices; the sludge suction device comprises a sludge pump, and a sludge suction port of the sludge pump is in the same direction as the drill bit;and a sludge outlet of the sludge pump communicates with outside through a slurry pipeline. According to the construction equipment, the drilling pressure is increased through the dead weight, and apower system of the reamers is provided, so that the purposes of destroying various geological soil layers through the reamers in the sludge suction process in water and then sucking sludge through ahigh power mud suction system are achieved; the feature of quick soil extraction under the shallow water or deep water conditions is achieved, so that the restrictions of certain water depth and geological conditions required by traditional mud suction are not required to be considered.

Description

technical field [0001] The invention relates to the construction field of undrained caisson sinking and soil extraction on land. More precisely, the present invention relates to a construction equipment for rapid underwater soil extraction. Background technique [0002] In recent years, my country's traffic construction has developed rapidly, and bridges are indispensable buildings in traffic construction. During the construction of bridge engineering, caisson is a common bridge foundation structure. The sinking of the caisson is to overcome the buoyancy, contact surface friction resistance, and end support force by its own gravity, and weaken the corresponding resistance by taking soil during the sinking of the caisson, and then sink. However, in the traditional dredging methods, hydraulic dredging and air dredging are limited by water depth and soil geological conditions. Contents of the invention [0003] The invention provides an underwater rapid earth-taking constr...
