Double-drill-bit pile body for construction

Abstract

The invention discloses a double-drill-bit pile body for construction. The double-drill-bit pile body for construction comprises a pile body, pile rods, drill bits, springs and pile covers; two vertical pile rods with the same heights are arranged in the pile body; stoppers are arranged on the outer sides of the pile rods; the springs are connected between the stoppers and the inner bottom of thepile body; the drill bits are arranged at the bottoms of the pile rods; and the detachable pile covers are arranged at the tops of the pile rods. Double drill bits are used for pile driving to achievehigh efficiency; the springs are arranged on the pile rods for relieving extrusion to reduce downward resistance of pile driving; the pile covers are detachable; and concrete can be filled in hollowstructures of the pile rods after pile body is driven into the ground, so that the manpower in pile driving is reduced.

Description

technical field [0001] The invention relates to a pile body, in particular to a pile body with double drill bits for construction. Background technique [0002] Civil engineering is a general term for the science and technology of building various engineering facilities. It not only refers to the applied materials, equipment and technical activities such as survey, design, construction, maintenance and repair, but also refers to the object of engineering construction, that is, the construction on the ground or underground, on land or in water, directly or indirectly for human life. Various engineering facilities for production, military and scientific research services, such as houses, roads, railways, transportation pipelines, tunnels, bridges, canals, dams, ports, power stations, airports, offshore platforms, water supply and drainage, and protection engineering. Pile driving is often seen in civil engineering. When driving existing piles, the pile body must be fixed by a...

Problems solved by technology

Pile driving is often seen in civil engineering. When driving existing piles, the pile body must be fixed by a machine first, and then the pile body is driven into the soil by a machine, or the small pile body is driven into the pile body through the support of the human body. Because the existing pile body The piling body adopts a single drill bit, which is very inefficient during piling, and is prone to breakage, with a high risk factor
