Description

Technical Field

[0001] The invention relates to the technical field of building construction equipment, in particular to a construction site pile driver. Background Art

[0002] A spiral pile driver is a mechanical device used to drive spiral piles into the soil at construction sites. This device is usually used in foundation treatment, building infrastructure and other projects, and is especially suitable for complex geological conditions such as soft soil, sand, and clay. The working principle of a spiral pile driver is to cut and lift the soil to the ground through a rotating drill bit, and at the same time inject concrete or mud into the hole to form a cylindrical pile foundation. This construction method has high construction efficiency and applicability. At the same time, compared with traditional pile foundation construction methods, it has lower pollution and mud emissions, and is more environmentally friendly.

[0003] The pile driver in the prior art easily causes dust to float when the drill rod is used to drive piles, which is not convenient for dust reduction.

[0004] A Chinese patent discloses a construction pile driver for construction engineering (authorization announcement number CN221423107U). The patent technology enables the construction pile driver for construction engineering to have the effect of conveniently sprinkling water to reduce dust during drilling and piling by setting a cylinder, a round rod, a turbine, a disc, an adjustment plate, a support rod, a matching plate, a fixing plate, a return spring, a delivery pipe, a water outlet hose and a nozzle. The nozzle sprays water to reduce dust, and the impact force of the water flow conveniently drives the turbine to rotate, thereby causing the nozzle to swing to increase the spraying area, improve the dust reduction effect, and achieve the purpose of improving practicality;

[0005] However, it has certain disadvantages: although it can perform preliminary adsorption treatment on the dust generated during piling through the nozzle, there will always be some dust in the air that cannot be captured by the directly sprayed water mist due to factors such as wind speed, particle size, and drifting height. These uncaptured dust will continue to float in the air, causing environmental pollution and obstruction of vision at the construction site. In addition, dust that is not handled in time will spread to farther areas with the flow of air, causing secondary pollution, which not only affects the environmental quality of the construction site, but also has an adverse impact on the lives and health of surrounding residents.
