[Construction Case] Industrial Waste Factory: Floor Slab Void Filling Work

[Construction Case] Industrial Waste Factory: Floor Slab Void Filling Work

The impact of weak ground! Introducing a case where 100% filling was achieved without gaps, eliminating voids and cavities under the floor.

We would like to introduce a case of "filling voids and cavities under the concrete floor" carried out at a waste disposal facility in Chiba Prefecture. Due to the influence of weak ground, the ground level dropped, creating large voids beneath the concrete floor. We injected polyurethane resin under the concrete to fill these voids. After construction, it can be visually confirmed that polyurethane resin has been filled directly beneath the areas where the concrete floor was excavated. 【Case Overview】 ■ Construction Area: Approximately 710m² ■ Maximum Void: 180mm ■ Area: Chiba Prefecture ■ Construction Period: 4 days *For more details, please refer to the PDF document or feel free to contact us.

Mitsuwa House Tech Co., Ltd. Ground Investigation, Surface, and Improvement Works

Mitsuwa House Tech Co., Ltd. Ground Investigation, Surface, and Improvement Works

Measure the soil penetration resistance, as well as the hardness or compactness, or the composition of the soil layers.

The Swedish sounding test is a method first adopted in 1913 by the Soil Committee of the Swedish State Railways to investigate the condition of poor roadbeds. It measures the penetration resistance of soil in situ to assess its hardness, softness, or compaction, as well as the composition of soil layers. Originally, Swedish sounding was primarily conducted manually (with two people operating it by hand), which sometimes resulted in slight variations in data due to the surveyor's experience. Therefore, Mitsuwa House Tech Co., Ltd. uses the latest machinery to ensure accurate data collection, connecting it to a laptop to allow for real-time verification of measurement data. Utilizing such machinery also enhances the image for clients. For more details, please contact us or refer to our catalog.

[Metal Road Construction Method Case Study] Nara Prefecture Road Improvement Project

[Metal Road Construction Method Case Study] Nara Prefecture Road Improvement Project

Ensuring safe and smooth passage! Case study of road improvement work on National Route 425, Jūzato to Sakon Nishikawa section (II-2 section).

National Route 425 in Nara Prefecture is a road that facilitates regional exchange, connecting the city of Gobō in Wakayama Prefecture and the village of Totsukawa in Yoshino County, Nara Prefecture. However, there are continuous sections with narrow widths and poor alignment, making it difficult for vehicles to pass each other in many areas. Therefore, construction was carried out with the aim of eliminating the narrow width sections, ensuring safe and smooth passage, and contributing to tourism promotion. The site is located within the area of the World Heritage Kumano Kodo, and due to the need for consideration of the landscape and the preservation of water channels, the metal road construction method was adopted. 【Project Overview】 ■ Client: Nara Prefecture, Gojō Civil Engineering Office ■ Construction Period: January 5, 2022 - June 30, 2022 ■ Total Length: 19.0m ■ Width: 6.95m *For more details, please refer to the PDF document or feel free to contact us.

[Metal Road Construction Method Case Study] Yamanashi Prefecture Road Improvement Project

[Metal Road Construction Method Case Study] Yamanashi Prefecture Road Improvement Project

Design and construction that avoids interference with existing structures is possible! Here is a case study on the main local road Fujikawa-Minobu Line.

Here is an example from the emergency road improvement and reconstruction project ordered by Yamanashi Prefecture. The Fujikawa-Minobu Line (Prefectural Road No. 10) is an important route designated as a second emergency transport road. The site had a thick alluvial fan layer, and existing structures (stone walls and drainage) were in close proximity, creating a challenging environment. As a result, the design and construction that could avoid interference with existing structures while ensuring traffic on the existing road was evaluated positively, leading to the adoption of the metal road construction method. 【Project Overview】 ■ Client: Yamanashi Prefecture, Kōnan Construction Office (Minobu Branch) ■ Construction Period: March 24, 2021 – August 31, 2022 ■ Total Length: 42.5m ■ Width: 7.0m (8.2m) *For more details, please refer to the PDF document or feel free to contact us.

Construction Case: Injection Work

Construction Case: Injection Work

Injecting a solidifying agent into the voids of sandy soil! Introducing a method to improve it into a stable ground.

"Injection" is a method of improving sandy ground by injecting a solidifying agent (chemical solution) into the voids of the soil to create a stable foundation. First, a survey is conducted to check for any obstacles, and the construction site is marked. A boring machine is set up, and while supplying drilling fluid (chemical solutions A and B), the drilling rod is pressurized and injected to drill to the specified depth. In the first injection, a quick-setting type of chemical is used to fill large voids in loose sand layers and cohesive soil sections, preventing the injected chemical from diffusing or escaping from the injection site. In the second injection, a medium-setting to slow-setting type of chemical is used to permeate and inject into the smaller voids of sandy ground that contain a significant amount of medium to well-compacted sand layers and cohesive soil, solidifying the ground as a whole. Once the specified injection amount for one stage is reached, the process moves to the next stage, and after repeating this for all stages, the chemical solution is replaced with water to fill the injection holes while withdrawing the rods. *For more details, please refer to the related link page or feel free to contact us.*
