Road Plus

Road Plus

A cantilever road widening method that allows for a maximum road widening of 1.75 meters to be constructed in a short period by installing it on existing roads.

■Reduction of environmental impact on the mountain and valley sides - Due to the cantilever structure, excavation of the mountain side is unnecessary, minimizing the impact on the valley side, such as rivers and waterways. ■Early traffic opening - By using precast products, temporary construction can be reduced, leading to a shorter construction period. ■Cost reduction possible - By removing part of the existing retaining wall's top and installing blocks, reconstruction of the retaining wall is unnecessary, resulting in cost reduction. ■Compatible with vehicle protective fences - It is compatible with vehicle protective fences (Type B and Type C), and the installation span for the P-type support allows for compatibility with both vehicle and pedestrian protective fences. ■Road widening according to regional characteristics - Depending on regional characteristics, it can accommodate specifications for either large vehicles or medium vehicles.

Drop structure waterway block

Drop structure waterway block

By converting on-site drop-off work to precast, significant reductions in construction time and improvements in productivity can be achieved.

■ By utilizing precast technology, we achieve significant reductions in construction time and improvements in productivity. ■ The use of hardware connections accelerates construction and reduces labor on-site. ■ It can accommodate drop heights of 500 to 1000 mm. ■ It is compatible with drainage flumes ranging from HF300 to HF900. ■ The standard extension for the waterway section is 4 meters for drainage flumes below HF500 and 6 meters for those above HF600. ■ By adjusting the extension and using a stepped drop, it can accommodate longitudinal slopes and effectively reduce flow velocity. *We can also consider specifications other than those listed. Please consult us.*

Precast Saya pipe block

Precast Saya pipe block

Suppressing the impact of bridge pier vibrations during an earthquake! It is possible to absorb the relative displacement between the bridge pier and the embankment, thereby mitigating the impact on the embankment.

The "Precast Sleeve Pipe Block" is a method for strengthening embankments, installed around bridge piers to prevent the transmission of vibrations from the piers during an earthquake. Products in circular or rectangular shapes are used vertically according to the shape of the bridge pier, creating a gap around the pier. This absorbs the relative displacement between the pier and the embankment, mitigating the impact on the embankment. 【Construction Procedure】(Step-by-step for each layer) (1) Delivery of materials (2) Assembly of U-shaped components (R components) (3) Joining treatment of components (4) Assembly of rectangular components (5) Pulling the product closer (6) Injection of upper and lower mortar (7) Installation of rubber plates (8) Completion of one layer

Kamaboko-shaped geta water block & itaotoshi

Kamaboko-shaped geta water block & itaotoshi

A water-saving and labor-saving set that ensures reliable water intake, conserves water resources, and reduces environmental impact.

■ By installation, we will reduce "ineffective discharge" and achieve water resource conservation. ■ By installation, we will reduce "ineffective discharge" and achieve water resource conservation. ■ The lifting handle makes it easy to discharge accumulated sediment and other materials. ■ By eliminating "overflow," we will not only eliminate "waste water" but also suppress "nutrient runoff," achieving water resource conservation and reducing environmental impact. ■ Since communication is not conducted, base station installation and communication volume are unnecessary. The simple structure is less prone to failure and easy to repair.

Fish Path SPIRAL

Fish Path SPIRAL

The method of stacking fishway blocks in an oval shape allows for a significant reduction in land area.

■The method of stacking fishway blocks in an oval shape significantly reduces the site area. ■The product shapes used for the curved and straight sections are standardized, which enhances workability. ■By creating a track shape with straight sections between the semicircular parts, it facilitates a pool flow condition that makes it easier for fish to ascend. ■The gradient of the fishway has the semicircular return section at level and the straight ascending section at a gentle slope of 1/10, improving ascent efficiency compared to a circular shape. ■The partition walls utilize an ice harbor method that accommodates small fish species. ■By rounding the overflow section of the partition wall, it creates a submerged flow that is easier for fish to ascend. ■Overflowing at the fishway outlet section adjusts the flow rate of the fishway. ■Light windows are installed to ensure adequate illumination.

Bird Fish Nest Block 'Σ "Sigma"'

Bird Fish Nest Block 'Σ "Sigma"'

You can freely choose the slope! This birdfish nest block can be used not only as a fish nest but also as a fishway.

This is a fish nest block that has a shape resembling a cut top slab and upper side walls of a box culvert. It creates natural-like depressions, making it suitable for the ecological environment of aquatic life. The block has good water and light permeability, making it conducive to the growth of aquatic plants, algae, and plankton. The inflow and outflow of sediment is relatively easy, which helps prevent functional degradation. By laying stones on the bottom slab, a natural environment is formed, suitable for the activities and spawning behaviors of aquatic life. Its stepped structure helps prevent water accidents caused by falls and slips, and provides a platform for cleaning operations within rivers. Patterns can be added to the front wall, harmonizing with the landscape. The slope can be freely selected (1: 0.5 to 2.0). Dead water areas are conducive to the growth of reeds and other vegetation, creating environments for bird nesting. It is easy to install and does not require specialized skills such as those needed for block work. It can be used not only as a fish nest but also as a fish passage.
