ROTARY NOZZLE
To provide a rotary nozzle which enables control of rotation of a rotary part in the underground of a foundation.SOLUTION: A rotary nozzle 1 is used for a foundation improvement device and rotated by a reactive force of a jet force of a fluid S. This nozzle is constructed such that a rotary part 20 having a fluid passage 21 formed to communicate with a fluid passage 12 is provided so as to be rotatable about a shaft 11 of a fixed part 10 having the fluid passage 12 formed so as to allow passage of the fluid S, a part 21b of the fluid passage 21 of the rotary part 20 is obliquely inclined outside a vertical surface with respect to the fluid passage 12, and formed toward the outer peripheral surface, a tip port 21c is provided to the tip of the inclined part 21b, the rotary part 20 is made rotatable about the shaft 11 by the reactive force of the jet force of the fluid S jetted from a jet nozzle 25 attached to the tip port 21c, and an elastic body 27 for sealing a space 26 between the fixed part 10 and the rotary part 20 and applying a brake on the rotary part 20 through expansion by a fluid A supplied from the other fluid passage 13 of the fixed part 10 is provided to an opening 26a of the space 26.SELECTED DRAWING: Figure 1
【課題】地盤の土中内での回転部の回転を制御することができる回転ノズルを提供する。【解決手段】地盤改良装置に用いられ、流体Ｓの噴射力の反力により回転する回転ノズル１において、流体Ｓが流通する流体通路１２が形成された固定部１０の軸部１１を中心として該流体通路１２に連通する流体通路２１が形成された回転部２０を回転自在に設け、流体通路１２に対する鉛直面外に回転部２０の流体通路２１の一部２１ｂを斜めに傾斜させて外周側に向けて形成し、この傾斜した一部２１ｂの先端に先端口２１ｃを設け、この先端口２１ｃに取り付けられた噴射ノズル２５から噴射される流体Ｓの噴射力の反力により軸部１１を中心として回転部２０を回転自在にし、かつ、固定部１０と回転部２０間の空間２６を封止すると共い、固定部１０の他の流体通路１３から供給される流体Ａにより膨張して回転部２０にブレーキを掛ける弾性体２７を空間２６の開口２６ａに設けた。【選択図】図１
