Hole guiding and pile planting equipment and construction method
The invention relates to the field of building construction, in particular to hole guiding and pile planting equipment and a construction method. The hole guiding and pile planting equipment comprises a hole guiding mechanism used for forming a drill hole in a construction site and a pile planting mechanism used for pressing a preset pipe pile into the drill hole. The hole guiding mechanism comprises a drill bit; a main blade is connected with the peripheral face of the drill bit; a plurality of branch blades are connected with the blade face of the main blade; and an included angle between each branch blade and the main blade ranges from 30 degrees to 90 degrees. The construction method adopting the hole guiding and pile planting equipment includes the steps of construction preparation, drilling and hole forming, cement pile manufacturing, core pile inserting and the like. According to the hole guiding and pile planting equipment and the construction method, through the mutual cooperation of the main blades and the branch blades, the stirring degree of cement paste is improved, so that the composition of the cement paste and mixing between the cement paste and soil particles in the drill hole are more sufficient, the cement paste is more uniform, the problem that the cement paste is locally solidified too early is solved, and a finally formed cement composite pile has better quality.
本申请涉及建筑施工的领域，尤其是涉及一种引孔植桩设备以及施工方法。引孔植桩设备，包括用于在施工场地形成钻孔的引孔机构以及用于将预置管桩下压到钻孔中的植桩机构；所述引孔机构包括钻头，所述钻头外周面连接有主叶片，所述主叶片的叶面上连接有多个支叶片，所述支叶片与主叶片之间的夹角为30‑90°。采用上述引孔植桩设备的施工方法，包括施工准备、钻进成孔、水泥桩制作、插入芯桩等步骤。本申请通过主叶片和支叶片的相互配合，提高了对水泥浆的搅动程度，从而使水泥浆自身组成以及水泥浆与钻孔中土体颗粒之间混合得更加充分，使水泥浆更加均一，并减少了水泥浆局部过早凝固的问题，使最终形成的水泥复合桩获得更好的质量。
