How does a hydraulic pile driver work?
Hydraulic pile drivers are powerful and efficient machines used on construction and civil engineering projects to drive piles into the ground. Piles are elongated structural elements made of steel, concrete, or wood that are driven into the ground to provide support for buildings, bridges, and ot...Read more -
Rotary Drilling Method
The rotary drilling method is a widely used technology in the drilling and excavation fields. The method involves using a rotating drill bit to cut through the earth’s surface to form boreholes used for a variety of purposes, such as oil and gas exploration, water well drilling, and constru...Read more -
Long spiral bored pile
Long spiral drilling pumping super fluid concrete rear reinforced cage technology is evolved by the Japanese CIP engineering method, it is different from ordinary drilling pile, it adopts special long spiral drilling machine drill to the predetermined depth, through the hole, to the pile top, and...Read more -
Causes of Sludge Generation in Rotary Drilling Piles and Clearing Hole Treatment
Rotary drilling piles, also known as bored piles, are a common foundation construction method used in civil engineering projects. During the construction process, a significant amount of sludge is generated as a byproduct. This sludge is a mixture of soil, water, and drilling additives, and it ca...Read more -
Why test pile before pile foundation construction?
Testing piles before pile foundation construction is a crucial step in ensuring the safety and stability of any structure. Pile foundations are commonly used in construction to support buildings and other structures, especially in areas with weak or unstable soil conditions. The testing of piles ...Read more -
RC DRILLING
>> Reverse Circulation is a drilling method widely used around the world. >> RC drilling uses dual wall drill rods consisting of an outer drill rod with an inner tube. These hollow inner tubes allow the drill cuttings to return back to the surface in a continuous, steady flow. >>...Read more -
Cause analysis and control measures of pile bottom sediment in rotary digging pile
The sediment of pile bottom may be generated in the construction of drilling holes, the placement of steel cage, and the pouring of concrete. The analysis shows that the causes of sediment can be roughly divided into the following categories: 1.1 Pile hole hole wall collapse 1.1.1 Cause Analysis ...Read more -
Problems and countermeasures of deep pile construction
1. The construction efficiency is low, mainly due to the high time of lifting the drilling tool and the low efficiency of the drill pipe to transfer the drilling pressure. the way to deal with a situation: (1) Increase the length of the drill bit to increase the amount of ballast per drill; (2) T...Read more -
What is a three-axis mixing pile?
]Three axis mixing pile is a kind of long spiral pile, pile machine has three spiral drilling at the same time, construction three spiral drilling down construction at the same time, generally used for underground continuous wall construction method, is an effective form of soft foundation treat...Read more -
Detection of the foundation treatment effect
1. Change the filling method After changing the foundation method, the ring knife method, static touch test, light dynamic touch test and standard penetration test should be used to test the effect of foundation treatment. During testing, the sampling point should be located at 2 / 3 of ...Read more -
Sand and silt layer rotary drilling method
1. The characteristics and risks of sand and silt layer When drilling holes in fine sand or silty soil, if the groundwater level is high, mud should be used to form holes for wall protection. This kind of stratum is easy to be washed under the action of water flow because there is no adhesion bet...Read more
