H-shaped bank protection pile construction method
An H-shaped bank protection pile construction method comprises the steps that firstly, a hole guiding device is aligned with a pile position, and the hole guiding device is made to be perpendicular; then the lifting mechanism is driven, and it is guaranteed that the hole guiding device slowly descends at the uniform speed; meanwhile, a high-pressure pump and a slurry pump are started; when the hole guiding device slowly and gradually descends, the knife edge firstly cuts into a soil body; then, high-pressure water flow sprayed by a high-pressure nozzle pipeline enters a high-pressure cavity, and the soil body in the high-pressure cavity is cut up instantly by a high-pressure water flow group; the chopped soil body is mixed with a water body in the high-pressure chamber to form slurry, and the slurry is led out from a plurality of slurry suction ports around the high-pressure chamber and is led away through a slurry suction branch pipe and a slurry suction main pipe, so that the output of the soil body is completed; and the hole guiding device continuously descends, the process is repeated till cutting is conducted to the designated depth, then the lifting mechanism is started, the hole guiding device is lifted upwards and guided out, and therefore an H-shaped guiding hole consistent with the H-shaped bank protection pile in appearance contour is formed. According to the H-shaped bank protection pile construction method, the construction speed can be increased.
一种H型护岸桩施工方法，先将将引孔装置对准桩位，并使引孔装置垂直；然后驱动升降机构，保证引孔装置缓慢、均速下降；同时，开启高压泵、泥浆泵；当引孔装置缓慢逐渐下降时，刀口首先切入土体；然后高压喷嘴管道喷出高压水流进入到高压腔室中，高压水流群瞬间将高压腔室中的土体切碎；切碎的土体与高压腔室中水体混合后形成泥浆，再由高压腔室周围多个吸浆口引出，通过吸浆支管、吸浆主管引走，由此完成土体的输出；引孔装置不断下降，重复上述过程，直至切削至指定深度，再启动升降机构，将引孔装置向上提升引出，由此形成了与H型护岸桩外形轮廓一致的“H”型引孔。本发明提供的一种H型护岸桩施工方法，可提高施工速度。
