Gas-water combined side resistance eliminating device
The invention discloses a gas-water combined side resistance eliminating device which is used for pulling out a pile foundation or a well casing and comprises a drilling machine support, a drilling machine tower is connected to the drilling machine support and used for lifting a steel wire rope, one end of the steel wire rope is connected with a drilling rod structure, the drilling rod structure is used for drilling an embedded pipe fitting, and the other end of the steel wire rope is connected to the drilling machine support. And the drilling machine support is fixed on the ground. The water pump and the air pump work at the same time, the effect of comprehensively flushing and eliminating side wall friction resistance is achieved, the drilling machine is used for lifting and driving the drill rod and the drilling tool to rotate, high-pressure mud generated by the water pump and compressed air generated by the air pump are synchronously conveyed to a drill bit in the drilling tool through the high-pressure rubber pipe, and the drill bit drills to disturb and break a soil layer; the mud is lifted, floated and returned out of an orifice through continuously input mud and compressed air, so that the side wall friction resistance around the pile foundation or the well casing is greatly reduced or basically eliminated, and the pile foundation or the well casing can be easily and quickly pulled out.
本发明公开了一种气水联合消除侧阻力的装置，用于对桩基或井管进行拔除，包括：钻机支座，钻机支座上连接有钻机塔架，钻机塔架用于提升钢丝绳，钢丝绳一端与钻杆结构连接，钻杆结构用于钻入埋入管件，钢丝绳另一端连接在钻机支座上，钻机支座固定在地面上。本发明通过水泵和气泵同时工作，达到一个综合冲洗消除侧壁摩阻力的效果，利用钻机提升和带动钻杆和钻具旋转，通过高压胶管将水泵产生的高压泥浆和气泵产生的压缩空气同步送至钻具中的钻头处，通过钻头钻进扰动破碎土层，通过不断输入的泥浆和压缩空气将泥土托举上浮返出孔口，从而极大减少或基本消除桩基或井管四周的侧壁摩阻力，让桩基或井管得以轻易快速地被拔出。
