Embodiment Construction

[0018] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0019] The present invention provides the first embodiment of the pile driver drill bit for prefabricated piles, which is specifically applied to the construction of hollow concrete prefabricated piles. For details, see figure 1 and 2 The pile driver drill bit includes a drill base 1, a soil cutting part 2 and an expanding wing 3 with a drilling cutter, the soil cutting part 2 is installed on the front end of the drill base 1, and the expanding wing 3 with the drilling cutter is swingably arranged on the drill base 1. The expansion wing 3 rotates with the drill bit base 1, and through the swing relative to the drill bit base 1, the cutting radius formed by the rotation of the drilling tool aro...

Abstract

The invention provides a drill bit of a pile machine, which comprises a drill bit matrix (1), a soil cutting part (2) and an expansion wing (3) with a drilling and digging knife, wherein the soil cutting part (2) is mounted at the front end of the drill bit matrix (1); and the expansion wing (3) is arranged on the drill bit matrix (1) in a swinging manner and rotates along with the drill bit matrix (1), and the cutting diameter formed by the rotation of the drilling and digging knife around the drill bit matrix (1) is changed through the swinging of the expansion wing relative to the drill bit matrix (1). The invention provides the drill bit of the pile machine, which is simple in structure and can be applied to building pile foundation construction under different geological conditions and in different areas.

Description

technical field [0001] The invention relates to the technical field of pile foundation construction, in particular to a pile driver drill bit. Background technique [0002] In today's infrastructure projects, the construction of pile foundations is particularly important. The use of prefabricated piles is very common in infrastructure projects. The selection of pile sinking methods should not only be based on engineering geological conditions, but also consider pile types, bottom section, length, site environment and design requirements. The current sinking of hollow concrete prefabricated piles The pile method mostly adopts the driving method, the pressing method or the mid-drilling implantation method. However, the structure, function and applicability of the pile driver drill bits of the current mid-drilling implantation method are relatively single, and cannot simply meet different geological conditions in different regions, structures in different regions, and pile fou...
