High-resistance hammering pile sinking system

Abstract

The invention discloses a high-resistance hammering pile sinking system. The high-resistance hammering pile sinking system comprises a pile body with the conical bottom, a middle pipe is arranged in the pile body, an upper pipe communicates with the upper end of the middle pipe, the upper pipe communicates with the outside, a lower ball communicates with the lower end of the middle pipe, and the lower ball is located at the bottom of the pile body; and the pile body is wrapped with a layer of metal net, a plurality of side pipes are embedded in the position, close to the outer wall, of the pile body, a plurality of side holes are formed in the upper sides of the side pipes in a lateral communication mode and communicate with the outside, and the gap between the metal net and the outer wallof the pile body is 1-3 mm. The high-resistance hammering pile sinking system has the advantages that the middle pipe is filled with water, a large amount of heat generated by friction of the outer wall of the pile body can be absorbed, when the pile cone impacts the pile body, the water in the middle pipe can move into an external water tank through the upper pipe, the heat-absorbed water can beexchanged with the outside, obvious temperature rise of the pile body is avoided, and the pile body is prevented from generating gaps with soil to reduce resistance.

Description

technical field [0001] The invention relates to the technical field of construction piling, in particular to a high-resistance hammering pile sinking system. Background technique [0002] With the development of the urbanization process, high-rise buildings in cities and towns have sprung up like mushrooms after a spring rain; a solid foundation needs to be laid before the construction of the building, and the construction team often uses the impact generated by the falling of the pile hammer to overcome the resistance of the soil to the pile. Allowing the pile to sink to the designed depth, this frictional resistance supports the vertical load created by the building above; [0003] In the prior art, when the pile body is hammered by the pile cone, the intense friction between the pile body and the soil or rock will cause the temperature of the pile body to rise sharply. The impact of pile sinking will cause the pile body to be in a certain expansion state after the pile s...

Problems solved by technology

[0003] In the prior art, when the pile body is hammered by the pile cone, the intense friction between the pile body and the soil or rock will cause the temperature of the pile body to rise sharply. The impact of pile sinking will cause the pile body to be in a certain expansion state after the pile sinking is completed, and it will shrink to a certain extent after cooling. Therefore, it is particularly important for us to propose a high-resistance hammering pile sinking system
