横山基礎工事 List of Products and Services

The "LIBRA Method" is a temporary bridge and cantilever construction method that simplifies the securing of pile alignment by using upper steel panels as guides for pile driving, eliminating the need for scaffolding until the upper structure is erected, and streamlining the complex reinforcement of bridge piers on sloped terrain. Since high-altitude work is not required, it ensures safety while reducing work time. It is often adopted as part of national resilience initiatives and has a wealth of experience in construction access roads and work platforms for the expansion of highways to four lanes, as well as disaster recovery projects. 【Features】 - Enables parallel work on upper and lower structures, reducing waiting time and shortening processes. - The connection points of the newly installed panels to the pile bridge piers serve as guides for steel pipe installation, eliminating the need for dangerous guide material installation work. This improves safety while also reducing changes to the natural terrain and minimizing deforestation, thereby lessening the impact on the natural environment. - Drilling and installation can proceed simultaneously, allowing for stable construction from soft ground to hard ground. - Adaptable to various site conditions such as steep slopes in mountainous areas, rivers, dams, ports, and urban civil engineering. *For more details, please refer to the materials.

The "Phoenix Stage Construction Method" is a rapid construction method for temporary piers suitable for maintenance and repair work during dry periods. In spaces with a clearance of less than 6 meters, it reduces the number of welding points on support piles using a low-head telescopic crane and the newly developed Phoenix Hammer, enabling high-quality rapid construction. Together with the LIBRA method, it rapidly constructs a working stage for various repair and reinforcement works, as well as disaster recovery works, including low-head spaces within rivers, creating a comfortable construction period. 【Features】 - Rapid construction of piers in working spaces under 6 meters - Pre-construction of superstructures via stay cable equipment - Simultaneous parallel construction of ground assembly and pile driving - Use of steel pipes as support piles *For more details, please refer to the PDF materials or feel free to contact us.

The "L Pier Construction Method" utilizes high-strength materials for the fabrication of girders and steel pipe piles, allowing for the use of large construction machinery capable of operating in an 8-meter width, achieving a maximum span length of 20 meters through vertical installation. This method can accommodate year-round placement within rivers, eliminating the need for repeated installation and removal during non-flood periods. As a result, it can be utilized for the construction, renewal, and maintenance of large river structures such as long bridges, as well as for wide-ranging disaster recovery and reconstruction projects, including construction piers, detours, and emergency bridges. It is the first long-span compatible LIBRA bridge. By connecting the pile frame with brace pipes and brace materials in a ground assembly and installing them as a unit, the need for lifting operations is eliminated, enhancing safety. **Features** - By pre-installing the assembled upper panels through reaction poles, safety and workability are improved. - The use of high-strength materials for the main frame enhances quality and strength. - Connecting the pile frame with brace pipes and brace materials in a ground assembly and installing them as a unit eliminates the need for lifting operations, improving safety. *For more details, please download the PDF or feel free to contact us.*
