Abstract
The invention discloses a hollow anchor rod drill bit which comprises an impacting blade, a dumping groove, a threaded connector and a cooling water hole, wherein the impact blade is made of carbon tungsten alloy materials. The hollow anchor rod drill bit is reasonable in structure, high in efficiency and long in service life.
Description
Technical field
The present invention relates to the drill bit that a kind of Geological Engineering is used, refer in particular to a kind of hollow bolt drill bit.
Background technology
Along with the increasing of the infrastructure construction dynamics such as traffic, the energy, in tunnel, basement and side slope, developed rapidly as the anchoring that can give full play to the rock mass self-stable ability, the rock bolt consumption grows with each passing day, and demonstrates vast potential for future development.Bolt support is a kind of most economical effective method that improves geotechnical engineering stability.
Wherein, the reliable in quality of hollow bolt, anchoring effect and reinforcement effect are far superior, and its application is more and more wider.The hollow bolt system can guarantee that between anchor rod body and hole wall, slip casting is full, gives full play to the anchoring effect of anchor pole.Supporting power (supporting plate power or prestressing force) can be provided after rock excavation immediately, effectively protect the inherent strength of rock mass, stop the loosening and distortion of country rock, strengthen the stability of geotechnical engineering.Its body of rod has enough slurries parcels, has greatly improved and has supported erosion-resisting ability, demonstrates good durability.It can avoid or extenuate the generation of collapse and cave-in accident and other engineering disease, and durability is remarkable, has long-term recessive economic benefit.
The drill bit of hollow bolt has varied, and every kind of drill bit has its characteristics, but there is the defective of unreasonable structure in the drill bit that has in prior art.
Summary of the invention
The object of the invention is to provide a kind of hollow bolt drill bit rational in infrastructure.
The technology of the present invention solution is: comprise and impact sword, ash pit, the body that is threaded, cooling water hole.
Wherein, above-mentioned impact sword is made by the diamondite material.
The present invention is rational in infrastructure, efficient work, long service life.
Description of drawings
Fig. 1 is structural representation of the present invention.
In figure:
1, impact sword; 2, ash pit; 3, the body that is threaded; 4, cooling water hole.
The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the present invention includes impact sword 1, ash pit 2, the body 3 that is threaded, cooling water hole 4.
Wherein, above-mentioned impact sword 1 is made by the diamondite material.
Claims (2)
1. a hollow bolt drill bit, comprise and impact sword (1), ash pit (2), the body that is threaded (3), cooling water hole (4).
2. hollow bolt drill bit according to claim 1, is characterized in that, described impact sword is made by the diamondite material.
