Extension rod type bidirectional cement-soil mixing pile machine under confined space
The invention relates to the field of mixing pile machines, in particular to a limited space lower connecting rod type bidirectional cement soil mixing pile machine which comprises a pile machine body, a rod shell, a rotating rod, a drill bit and a power generation device. During construction, the first section of rotating rod is drilled into the ground, the remaining rotating rods are sequentially connected to the first section of rotating rod, so that the mixing pile machine can complete construction in the environment where the vertical space is limited by high-voltage lines, low-clearance bridges and the like, and when the soil densities are different during construction and a drill makes contact with low-density soil, the construction efficiency is greatly improved. The contact block does not abut against the contact point under the action of the elastic piece, the motor is powered off, and the drill stops rotating, so that the drilling resistance at the high-density soil is increased; the drilling resistance of the positions of the drill bits is similar or identical, the drill bits are prevented from deviating, drilled soil can be stirred more loosely through the stirring blades in the drilling process, and cement paste and the soil can be stirred more evenly in the re-stirring process.
本申请涉及搅拌桩机的领域，一种受限空间下接杆式双向水泥土搅拌桩机，其包括桩机机体、杆壳、转杆、钻头和发电装置。本申请可以在施工时先将第一节转杆钻入地面，并将剩余转杆依次连接至第一段转杆，使搅拌桩机可以在受高压线、低净空桥等垂直空间受限的环境中完成施工，而在施工时存在土壤密度不同的情况，钻子接触低密度土壤的情况下，接触块在弹性件的作用下不抵接接触点，电机断电且钻子停止自转，以增大高密度土壤处的钻进阻力；利于钻头位置的钻进阻力相近或相同，利于防止钻头发生偏移，并且可以在钻进的过程中通过搅拌叶将钻开的土壤搅拌的更为松散，且在复搅的过程中，可以将水泥浆与土壤搅拌的更加均匀。
