Types of Button Valves

Dia: 13mm in plastic or steel
Dia: 16mm in steel 

They are produced by metal/plastic and rubber.

Micropiles, also known as minipiles or pin piles, are slender foundation elements used in construction to transfer loads to deeper, more stable soil layers. Their small diameter and ability to be installed in limited access areas make them a popular choice for urban environments and structures with restricted space. Recent advancements in micropile technology have introduced a disposable button valve, offering several benefits and revolutionizing the construction process.

The Function and Importance of the Button Valve:

The button valve plays a crucial role in micropile installation as it ensures the stability and integrity of the structure. In typical micropile construction, a steel casing is advanced into the ground followed by drilling and injecting grout. The button valve is installed at the bottom of the casing to prevent the loss of grout during placement, maintaining the frictional bond between the surrounding soil and the casing. This bond is essential for load transfer and the overall strength of the micropile.

Advantages of Disposable Button Valve:

1. Cost-Effectiveness:

Disposable button valves significantly reduce the overall cost of micropile construction. Traditional steel valves require extensive cleaning and refurbishment after each use, which can lead to increased expenses. In contrast, disposable valves eliminate the need for cleaning and are readily available at a lower cost, making them a more economical choice.

2. Time Efficiency:

The use of disposable button valves streamlines the micropile installation process. The valves can be quickly inserted into the casing, ensuring time efficiency on the job site. This allows for faster project completion, reducing labor costs and potential disruptions to nearby activities.

3. Improved Construction Quality:

Since disposable button valves are new for each project, they offer enhanced construction quality. There is no risk of contamination or compromise to the performance of the valves due to wear and tear. The use of new valves for every micropile installation ensures consistent performance and reliable load transfer capacity.

4. Environmental Considerations:

Disposable button valves are designed with environmental consciousness in mind. Being single-use and made from recyclable materials, they minimize waste generation on construction sites. Their disposal after each project reduces the environmental footprint of micropile construction.

Conclusion:

Disposable button valves present a revolutionary solution for micropile construction. They offer numerous advantages, including cost-effectiveness, time efficiency, improved construction quality, and environmental considerations. With these benefits, disposable button valves are rapidly becoming the preferred choice for contractors and engineers involved in micropile application, ensuring stable and reliable foundations for various structures.
