Description
Rotary Drilling Auger are particularly divided into the following types:
1) Single Cut Conical Rock Auger
2) Double Cut Single Carry Conical Rock Auger
3) Double Cut Double Carry Conical Rock Auger
4) Sinble Cut Flat Rock Auger
5) Single Cut Flat Clay Auger
6) Double Cut Single Carry Flat Rock Auger
7) Double Cut Single Carry Flat Clay Auger
8) Double Cut Double Carry Flat Rock Auger
9) Double Cut Double Carry Flat Clay Auger
Application of Drilling Auger:
(1) Conical auger: double cut double carry augers, suitable for hard bedrock. Double cut single carry augers, suitable for weathered bedrock, pebble, frozen soil, etc. The above augers are equiped with various cutting teeth, and many types of augers can be derived from the changes of tooth type, and pitch, etc.
(2) Straight auger:
a. Straight augers with bucket teeth: double cut double carry augers, suitable for sand, small diameter gravel layer with poor cementation; double cut single carry, suitable for sand and soil layer; single cut single carry, suitable for pebbles with large diameter, cohesive soil and hard clay with poor cementation.
b. Straight augers with bullet teeth: double cut, three cut and four cut, suitable for hard bedrock or gravel
Rotary drilling tools are devided into the following types:- Double bottom double cut drilling bucket: a standard drilling tool for rotary drilling rig. When applied for below 500KPa total or strongly weathering rock layer, flat bucket teeth would be used as the cutting bits for drilling buckets; When applied for below 30MPa gravel, cobble and boulder layer and total or strongly weathering sedimentary rock layer, bullet teeth would be used.
2.
Clam drilling bucket: high drilling efficiency and easily unloading the slag, especially suitable for piles of smaller diameter. It is widely applied in China for clay layer, plastic rock layer, dense gravel and cobble layer, and slightly hard sedimentary rock layer, etc.
3. Core barrel: with all kinds of carbide cutting bits around the bottom of the shell, the core is broken at the joint crack, and taken out of the hole with the core barrel. When applied for below 90MPa, bullet teeth would be used as the cutting bits for the core barrels; When applied for above 60Mpa, roller bits would be a better choice as the cutting bits for the core barrels.
4. Auger, previously as a standard drilling tool for rotary drilling rig, nowadays is gradually replaced by other drilling tool types in China, because of the low unloading performance, and low drilling performance for hard rock layer. However, augers are still suitable for dry piling construction and casing drilling construction, and gravels, boulders and total or strongly weathering rock layer.
5. Belling bucket: for improving the bearing capacity of the pile bottom.
6. Clean-out drilling bucket: for furtherly cleaning out the slag from the pile bottom.
***Casing, as a supplement for drilling tools, is for protecting the pile wall from collapse in loose formation, and prevent groundwater into the pile, and benefits the decrease of pile gradient. Casing consists of single wall casing and double wall casing. Casing elements include casing driver, casing, casing shoe, etc.In accordance with the complicated construction requirement, we have produced more than the above mentioned types of drilling tools. Here is some samples as below: For any advice about selection of rotary drilling tools, please email usProduction of rotary drilling toolsThe production of rotary drilling tools must be carried out in strict accordance with the process standards. The process quality control work should be done well. The self-inspection, mutual inspection, general inspection system should be checked, and the quality records should be kept timely, accurate, clear and complete to ensure product qualityShipment and package of rotary drilling tools:- Package: iron support and wrapped with plastic film
- Transportation: by sea, land and air.
- Main ports: Manzhouli, Tianjin, Qiangdao, Shanghai, Yiwu, Taizhou, Shenzhen, Guangzhou, Ruili, Pingxiang, Horgos, etc.
- Delivery: Fast and timely delivery.
Our products at construction sites: - Technologists' regular investigation on construction sites promotes product optimization and innovation.
- Many experiments on the construction sites help to design some new type drilling tools.
- RIGPA rotary drilling tools with high and stable quality has been highly recognized by the customers, and widely introduced to other customers.
- When the rotary drilling rig is working, the operator has to observe and master the geological structure cross-sectional view of the working area, the viaduct cable line, the building construction, etc.
