Pile sinking ring rolling machine

Abstract

The invention provides a static pile driver and reaming and pile sinking machine combination. The static pile driver and reaming and pile sinking machine combination comprises a static pile driver and a pile sinking and reaming machine, wherein the pile sinking and reaming machine is connected with the static pile driver through a fixed platform; a platform cylinder is installed between a moving platform and the fixed platform; a derricking cylinder is installed between the moving platform and a beam; the beam is connected with a power head; the power head can slide up and down along the beam; a chain shackle is connected to one end of the beam; one end of a dual-wall drill pipe which is fixed to the chain shackle can slide up and down along with the power head; the other end of the dual-wall drill pipe is connected with an umbrella-shaped reaming drill; a manipulator used for fixing the dual-wall drill pipe is fixed on the beam; and a clamp holder is fixed on the beam. By the static pile driver and reaming and pile sinking machine combination, the work efficiency of pile pressing is improved, the counter weight is less for the same bearing weight of a single pile, squeezed oil is less, noise is low, less soil is squeezed, and no pollution is caused.

Description

technical field [0001] The invention relates to the technical field of static pile driving machine reaming and pile sinking, in particular to a pile driving and reaming machine. Background technique [0002] Existing presses include static pile presses, pneumatic hammer pile presses, and spiral pouring pile machines. Traditional static pile presses are difficult to press piles in sand, hard soil, and differentiated layers, and even in Under some geological conditions, the traditional static pile driver cannot perform pile pressing work, and the static pile driver has a high degree of damage to geological layered piles such as sand layers, hard soil layers, and differentiated layers. The piles formed by spiral irrigation also have many disadvantages, such as: the strength and hardness of the spiral irrigation piles are not good enough, and the formation period of the spiral irrigation piles is long. The general pile sinking method has the following three kinds: one, the stat...

[0002] Existing presses include static pile presses, pneumatic hammer pile presses, and spiral pouring pile machines. Traditional static pile presses are difficult to press piles in sand, hard soil, and differentiated layers, and even in Under some geological conditions, the traditional static pile driver cannot perform pile pressing work, and the static pile driver has a high degree of damage to geological layered piles such as sand layers, hard soil layers, and differentiated layers.

The piles formed by spiral irrigation also have many shortcomings, such as: the strength and hardness of the spiral irrigation piles are not good enough, and the formation period of the spiral irrigation piles is long

The general pile sinking method has the following three kinds: one, the static pressure pile method, through the mechanical static pressure or the hydrostatic pressure effect, realizes the construction method of the pile body pressed into the soil layer, and its shortcoming is that when encountering hard soil layers, sand layers, In the case of different layers and some soil layers that are not easy to press piles, it is impossible to achieve greater penetration, and the existing static press machine cannot further press the piles downward; second, the hammering pile sinking method, through mechanical hammers such as diesel oil The cyclic impact of the hammer on the pile body realizes the construction method of driving the pile body into the soil layer. Its disadvantage is that it produces relatively large noise and vibration, which directly affects the surrounding buildings; Then, a pile sinking construction method of implanting steel cages and concrete in the hole has the disadvantages of concealed engineering, difficult quality control, and a large amount of mud waste, which is difficult to handle and has high requirements for environmental protection. Standards are required
