Project Overview 1, the project location: the project location on the equipment transfer costs, material procurement, season, weather, engineering unit price have an impact, so these factors need to be considered. 2、Type of project: There are many types of project foundation, such as high spee Read More

Rotary drilling rigs play a crucial role in modern foundation engineering, and their rock penetration ability directly determines construction efficiency and pile quality under complex geological conditions. The key to rock penetration lies not only in the overall performance of the equipment but al Read More

Rotary drilling rigs are widely used in foundation engineering due to their efficiency and flexibility. However, drilling through hard rock significantly increases the difficulty of construction, demanding better equipment performance and advanced operational techniques. To enhance drilling efficien Read More

Introduction of advantages of rotary drilling rigThe hole formation of rotary drilling rig is firstly to break up the rock and soil through the slewing of the barrel drill bit with a flap at the bottom and load it into the drill bit directly, and then the drill bit will be raised out of the hole by Read More

Rotary drilling hole filling pile, also known as positive and negative circulation hole filling pile, is the most commonly used and widely applied pile forming method in China, which is to use general geological drilling rigs under the condition of mud wall protection, slow drilling, slagging throug Read More
