Hydrodynamic force pile side penetrating grouting device
The invention discloses a hydrodynamic force pile side soil penetrating grouting device which comprises a soil penetrating pipe, an impeller, a reduction gear and a gearbox. The soil penetrating pipe comprises a conical tip, a rubber sleeve, a slurry outlet hole, an external thread, a pipe body, a slurry inlet hole, a tooth-free section, a head sealing plate and a cavity; a conical tip is arranged at one end of the pipe body, the outer side face of the part, except the conical tip, of the pipe body is divided into an upper part, a lower part, a front part and a rear part, the upper part and the lower part are arc surfaces, the front part and the rear part are planes, two symmetrical grout outlet holes are formed in the front end, close to the conical tip, of the pipe body and wrapped by a rubber sleeve, and the rubber sleeve is arranged outside the pipe body in a sleeving mode. External threads are arranged on the arc surface of the outer side of the pipe body; the buried pipe can horizontally penetrate into the soil layer on the pile side, after the cast-in-place pile reaches certain strength, grouting reinforcement is conducted on the soil body around the pile, the strength of the soil body around the pile is improved, and the effect of improving the bearing capacity of a single pile is achieved; and a pair of U-shaped grouting pipes can be connected with a plurality of fluid power pile side soil grouting devices, so that the aim of one-time multi-point reinforcement is fulfilled.
本发明公开了一种流体动力桩侧入土注浆器，包括入土管、叶轮与减速齿轮及齿轮箱；所述入土管包括锥尖、橡皮套、出浆孔、外螺纹、管体、进浆孔、无牙段、封头板和空腔；所述管体的一端设置有圆锥形的锥尖，所述管体除去锥尖的部分外侧面分为上下前后四部分，且上下两部分为圆弧面，前后两部分为平面，所述管体靠近锥尖的前端设置有两个对称的出浆孔，且通过橡皮套包裹，所述橡皮套套在管体外；所述管体外侧圆弧面上设置有外螺纹；本发明可将入土管水平贯入桩侧土层，在灌注桩达到一定的强度后，对桩周土体进行注浆加固，提高桩周土体强度，达到提高单桩承载力的作用；一副U形注浆管可连接多个流体动力桩侧入土注浆器，实现一次性多点加固的目的。
