Problems solved by technology

[0002] In building construction, piling is usually used to enhance the stability of the house foundation, so that the built house is stable and reliable, preventing damage to the house due to instability such as foundation subsidence, and at the same time enhancing resistance to natural disasters such as typhoons and earthquakes ability, and the piling process usually uses piling equipment to drive, press or vibrate the pile into the soil. These piling methods should not only consider the noise generated by piling, the bearing capacity of the pile when it is impacted, and the hardness of the soil, etc. , the construction efficiency is not high, and once the construction building needs to be relocated or demolished, it is difficult to dismantle the piles laid under the building. polluted environment

Abstract

The invention belongs to field of building construction equipment, and discloses a spiral detachable column pile. The spiral detachable column pile comprises a screw, a steel tube and a dovetail slot slide block mechanism, wherein the lower end of the screw extends into the steel tube and is rotatably mounted on the steel tube; the dovetail slide block mechanism comprises a middle dovetail slot slide block and outer dovetail slide slot blocks; the middle dovetail slot slide block is in threaded connection on the screw and is arranged on the screw in a penetrating mode; a plurality of dovetail lug bosses are uniformly arranged in the peripheral direction of the outer wall of the middle dovetail slot slide block; dovetail slots matched with the dovetail lug bosses are formed in each outer dovetail slot slide block; and the screw can rotate to drive the middle dovetail slot slide block to move up and down, so that the outer dovetail slot slide blocks are driven to move in the radial direction of the screw. According to the spiral detachable column pile disclosed by the invention, a threaded tip end at a lower end is screwed into soil, so that noises generated during piling are avoided and the column pile is prevented from impact, and therefore, piling efficiency is improved.
