The invention discloses an open caisson intelligent excavation device applied into an open caisson. The open caisson intelligent excavation device comprises a plurality of water supplementing devicesdistributed around the caisson wall of the open caisson at intervals, and an intelligent control device; each water supplementing device is composed of a water supplementing pipe, a rotating head anda water jetting gun head, wherein the fixed end of the rotating head is detachably mounted on the caisson wall of the open caisson and communicates with the water supplementing pipe, the rotating endof the rotating head can rotate and communicates with the water jetting gun head; the water jetting gun heads face the bottom of the open caisson and used for jetting water to impact a soil body, so that the undisturbed soil body is turned into slurry; and the intelligent control device monitors the condition of the soil body at the bottom of the open caisson in real time, the angles of all the rotating heads are adjusted according to the soil body situation, and then the jetting direction of the water jetting gun heads are adjusted. An automatic control console adjusts the angles of water jetting openings of the rotating heads, the soil body is scoured to be the slurry, then the slurry is sucked by a slurry suction pump to be discharged out of the open caisson, and the open caisson intelligent excavation device is reasonable in structure, easy and convenient to construct, efficient in operation, high in practicability and suitable for intelligent excavation of open caissons with various soil property types.
Description
technical field [0001] The invention relates to the technical field of large caisson excavation. More specifically, the present invention relates to an intelligent caisson excavation device and a method for excavating caissons using the device. Background technique [0002] With the development of traffic construction, large-scale caisson foundations have been widely used in the field of bridge construction, and caisson excavation and sinking methods have also received more and more attention. During the excavation and sinking operation of ordinary caissons, the investment of human resources is huge, and the efficiency of mud suction equipment is low. The method of earth extraction from ordinary caissons can no longer meet the needs of rapid earth extraction from large caissons. Needing to provide a kind of high-efficiency caisson fast construction method has become the task of top priority. Contents of the invention [0003] The invention provides an intelligent caisson...
