Thermal performance of cast-in-place piles with artificial ground

During the construction of cast-in-place piles in warm permafrost, the heat carried by concrete and the cement hydration reaction can cause strong thermal disturbance to the surrounding permafrost. Since the bearing capacity of the pile is quite small before the full freeze-back, the quick refreezing of the native soils surrounding the cast-in-place pile has

Load Testing and Interpretation of Instrumented Augered Cast-in-Place Piles

Abstract Given that piles are composed of different materials and installed using a variety of methods, ASTM D 1143/D 1143M-07 Standard Test Methods for Deep Foundations Under Static Axial Compression is justifiably general so that it has as many applications as reasonably possible. There are aspects of the test setup, the test procedures, and data

Field study on post-grouting effects of cast-in-place bored piles

The post-pressure grouting technique has proven to be an effective method to enhance axial resistance. In this paper, field tests were conducted to investigate the performances of large-diameter cast-in-place bored piles for six combined side-and-tip grouting piles and two side-grouting piles in extra-thick fine sand layers. The load–displacement response, shaft

It intends to support their decision in favor of testing the proper construction of their pile design, looking for Flaws, Defects, and Anomalies of cast-in-place piles, so they can have an assurance that their design was properly implemented in the construction site.

Managing the Installation of Augered Cast-In-Place Piles

Augered cast-in-place (ACIP) piles, known in Europe as contin uous flight auger piles (and by several other names in the United States) are low-vibration, low-displacement, and frequently low cost deep-foundation elements commonly used to support loads between 40 tons (0.36 MN) and 80 tons (0.71 MN). ACIP piles,

Cast-in-place pile foundation of solar cell panel support

The cast-in-place pile foundation of the solar cell panel support resolves the problems that in the prior art, the environment is not protected and construction cost is high, and provides a

Accurate detection technology of super long bored cast-in-place pile

Therefore, in view of the technical problem that it is difficult to accurately measure the concrete elevation and laitance thickness during the pouring of super long bored cast-in-place pile, this paper puts forward the accurate detection technology of pouring thickness of super long bored cast-in-place pile based on ultrasonic inclined plane reflection measurement, which

XM/M--Micro Cast-in-place Piles

Photovoltaic cast-in-place piles are an important part of solar photovoltaic power generation system, which is used to support and fix photovoltaic modules. Here are some construction cases to show the application of cast-in-place piles in practical engineering. Case 1: In a photovoltaic power station project, photovoltaic cast-in-place piles

What are the different types of PV Racking Ground Mounts

Drive piles are usually found in larger projects. The pile consists of galvanized steel I-beams, channel steel or columns. Use special heavy machinery to drive the pile into the ground. Appropriate soil conditions must be in place to drive the pile. These conditions include good soil cohesion, resulting in high pull-out strength and limited
