Drilling Bucket

This type of product is mainly composed of connecting kelly box, upper cover plate, cylinder body, upper and lower bottom plates, cutting tools, pressure rod mechanism, etc. It is divided into two types: soil layer and rock embedded type. During construction, a connecting kelly box is connected to the drilling rig, and cutting tools such as bucket teeth and picks are used to break the formation, and at the same time collect the drill cuttings at the bottom of the hole into the drill barrel. After the drill bit is lifted, the pressure rod mechanism on the upper part of the drill bit is pressed through the drilling rig pressure plate. Open the top to open the bottom plate of the drill bit hung by it, and pour out the extracted cuttings; then drill down the hole and cycle the above process to complete the drilling operation.

Product performance features:

Cutting tools can use soil teeth, bullet teeth, or combination teeth. The double-layer bottom plate design ensures that drill cuttings are effectively stored in the barrel.

Applications:

In January 2006, China Railway 14th Bureau constructed a large bridge on Jiqing Expressway in Changyi, Shandong Province. The pile diameter was φ2500mm. The strata were: Quaternary overburden, plastic clay, hard clay, sand layer, strong to moderately moderated mudstone, and sandstone. wait. The φ2500 rotary drilling bit developed by us was selected and achieved good drilling results. The hole was more than 80 meters deep and was drilled in less than one day. The income from each hole was about 100,000 yuan, which achieved particularly significant economic benefits.
