We would like to introduce the excellent economic efficiency of the "Super Rappuru Elniido Construction Method." Since it is constructed through direct excavation, it reduces the processes of over-excavation and the setting and removal of formwork. Construction can be completed in a short time from excavation to site preparation for each location. Through numerous test constructions in various ground conditions, we have established know-how in test systems, mix planning, construction management, and the development of mixing buckets, enabling us to create high-quality site preparations with minimal variation in strength. 【Features】 ■ Easy confirmation of support layers ■ Shortened construction period and high-quality site preparation ■ Minimal excess soil on site (disposal soil volume) ■ Agile response to various sites ■ Capable of handling sudden rain and groundwater *For more details, please download the PDF or feel free to contact us.

Ground improvement work in remote islands and mountainous areas. The biggest factor driving up costs is "transportation costs for equipment and materials." Our Elneed method (Super Laple method) solves this issue, which can sometimes amount to tens of millions of yen. The key is "overwhelmingly low equipment requirements." Since no special machinery or large-scale equipment is needed, transportation costs are dramatically reduced, making it possible to carry out projects that were previously abandoned due to unsuitable conditions. ⬛︎ Why is it "possible to construct anywhere"? 1. Only "backhoe" is needed. We do not use specialized heavy machinery like ground improvement dedicated machines. As long as a backhoe, which can be arranged anywhere, is available, construction can proceed. 2. Materials can be transported as "powder." Since we do not use ready-mixed concrete, there are no time constraints like the 90-minute rule to maintain quality. Cement-based materials can be transported in powder form and simply mixed with water on-site. This poses no problem even in remote islands or mountainous areas without ready-mix concrete plants. Thanks to this simplicity, we have successfully completed projects in more than three remote islands without regular shipping routes. Compared to other methods, we significantly reduce transportation costs and effort, contributing to the realization of projects.

I am anxious about whether we are truly reaching the "support layer" that serves as the foundation of the building. In other methods, the conditions underground can only be estimated from machine readings, making it difficult to determine their accuracy. The Super Rappu Elneed method allows us to "directly see and touch" the most important part of ground improvement. ⬛︎ The challenge of "invisibility" faced by other methods While other methods use specialized large machines to dig underground, the Super Rappu Elneed method employs the most common equipment on site, the "backhoe." Instead of estimating "numbers" like torque values or ammeter readings, we verify with the technician's "eyes." This simple and direct approach creates an overwhelming "certainty" that other methods lack. ⬛︎ "Visible reassurance" achieves optimization of quality and cost The advantage of being able to "visualize" the support layer goes beyond mere peace of mind. - Proof of overwhelming quality - Cost optimization - Prevention of troubles before they occur Because the work underground is invisible, we ensure reliable construction.

Can we achieve an overwhelming reduction in construction time? ⬛︎Explanation 1: No "slurry production" (compared to cement milk/pile improvement) In the cement milk method and pile improvement, the process begins with "slurry production," where cement and water are mixed at a batch plant. In fact, this preparation alone takes about 90 minutes for a site using 30 tons of cement. The Super Rappu Elneed method eliminates this entire preparation process. Since the solidifying agent is directly inserted in its package, there is no need for a plant or slurry production. The insertion work that took 90 minutes is completed in just 5 minutes. ⬛︎Explanation 2: No "formwork assembly and dismantling" (compared to the Rappu method) In the Rappu method, after "excavation," "formwork assembly" is performed, and after the concrete hardens, "formwork dismantling" occurs. These tasks require specialized craftsmen and are time-consuming processes. The Super Rappu Elneed method utilizes the sides of the excavation hole as a substitute for formwork (earthen formwork), eliminating the entire series of tasks related to "formwork." This allows for reductions in work time, labor costs, and material costs.
