Two-way extrusion equipment for prefabricating soil pile

Abstract

The invention relates to a two-way extrusion equipment for prefabricating a soil pile. The two-way extrusion equipment comprises a supporting frame main body and a feeding mechanism; an upper extrusion assembly is arranged on the upper portion of the supporting frame main body, a forming assembly and a nesting assembly are arranged on the lower portion of the supporting frame main body, and a discharging opening of the feeding mechanism communicates with a feeding opening of the forming assembly; the upper extrusion assembly and a lower extrusion assembly can move upwards and downwards respectively, stretch into the forming assembly and conduct two-way extrusion forming on raw materials located in the forming assembly at the same time to form the soil pile; and the nesting assembly is connected with the upper end of the forming assembly and can drive the forming assembly to move upwards after extrusion is completed, so the formed soil pile is separated from the forming assembly. Two-way extrusion forming can be carried out on the raw materials through the upper extrusion assembly and the lower extrusion assembly, and the compactness of the formed soil pile is more uniform; meanwhile, the nesting assembly drives the forming assembly to move upwards, feeding, pile pressing and pile discharging of a precast pile are integrated, procedures are saved, the production cost is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of prefabricated piles, in particular to a bidirectional extrusion equipment for prefabricated soil piles. Background technique [0002] As the speed of national infrastructure construction increases year by year, prefabricated piles, as a mature pile type, are widely used in various engineering construction fields because of their advantages of easy guarantee of pile quality, ability to withstand large loads, and durability. The number of applications is huge. Prefabricated piles can be manufactured in factories or on construction sites according to usage requirements and construction plans. When making prefabricated piles, it is necessary to carry out processes such as feeding, pile pressing, and piling out to complete a complete prefabricated pile. When the pile is formed, the density is not uniform. In addition, when the pile is pressed and the pile is unloaded, the piling equipment is used to perform ...

Problems solved by technology

When making prefabricated piles, it is necessary to carry out processes such as feeding, pile pressing, and piling out to complete a complete prefabricated pile. When the pile is formed, the density is not uniform. In addition, when the pile is pressed and the pile is unloaded, the piling equipment is used to perform the piling operation first, and then the pile barrel after the piling is completed is transferred to the pile unloading equipment. The pile equipment carries out the pile-out operation on the mud in the pile barrel. On the one hand, this will increase the pile-making process, reduce production efficiency, and increase production costs. On the other hand, too many processes will reduce the safety of production. There may also be accidents in the process, which greatly increases the probability of safety accidents
