Double Pipe Strainer Method for the stability of shafts and shields, and protection of soil retention deficiencies.

Double Pipe Strainer Method for the stability of shafts and shields, and protection of soil retention deficiencies.

Forming a homogeneous improved ground by injecting quick-setting grout using a double pipe and a special tip device. Construction is environmentally friendly with minimal industrial waste disposal.

This construction method is based on performing primary injection using a double-tube injection rod at each step to inject a quick-setting gel time while preventing diffusion beyond the specified area, followed by secondary injection to inject a slow-setting gel time to achieve uniform penetration into the voids between soil particles, thereby forming a homogeneous improved ground. 【Applications】 ● Stabilization of the bottom slab and backfill of the shaft (waterproofing and increased strength) ● Protection of soil retention deficiencies ● Stabilization of the face of shield tunneling or thrusting ● Prevention of loosening in the route section of shield tunneling or thrusting ● Stabilization of the backfill and bottom slab of deep foundations (waterproofing and increased strength) 【Features】 ● It hardens to a moderate firmness, so it does not interfere with excavation. ● The machinery is compact, allowing for construction in narrow areas. ● It can be applied freely in any direction, 360 degrees. ● There is minimal industrial waste, enabling environmentally friendly construction. ● It can be applied to all types of ground (especially effective for sandy soils). ● It generates little vibration and noise.

Reinforcement and liquefaction measures directly beneath structures, seismic retrofitting of foundations using the "Expacca Method."

Reinforcement and liquefaction measures directly beneath structures, seismic retrofitting of foundations using the "Expacca Method."

A rapid infiltration injection method that allows for injection at a wide injection interval (2 to 4 m) with a large discharge rate (20 to 30 ℓ/min).

The Expakka method is an abbreviation for the Expand Packer method. This method allows for the formation of a soil packer larger than the drilling diameter by expanding a geo-bag in the ground, thereby securing a large columnar permeation source between the upper and lower soil packers. This enables a larger spacing between drill holes and allows for extensive injection through low-pressure permeation between soil particles with a large discharge volume. [Applications] ● Reinforcement and liquefaction countermeasures directly beneath structures ● Seismic strengthening of foundations ● Base improvement associated with excavation work ● Construction of impermeable walls for tank foundations ● Prevention of suction and reinforcement of riverbanks ● Reinforcement associated with tunnel excavation work ● Reinforcement of missing sections of underground diaphragm walls

Ground improvement / A consistent cylindrical diameter is expected for any type of soil with the "X-JET Method."

Ground improvement / A consistent cylindrical diameter is expected for any type of soil with the "X-JET Method."

Cutting with two intersecting jets allows for excellent mixing and stirring, enabling the creation of high-quality modified bodies. It also exhibits excellent adhesion to retaining walls and structures.

The X-JET method involves cutting the ground by horizontally injecting ultra-high-pressure water mixed with air from a rotating triple-pipe rod, while simultaneously filling it with hardening material and discharging slime to the surface, thereby creating a cylindrical improved body of a certain diameter. 【Applications】 ● Improvement of the base during excavation / Pre-embedded underground beams ● Prevention of subsidence in newly constructed roads ● Shield launch and arrival protection ● Reinforcement of tunnels ● Water stop reinforcement for gaps in retaining walls ● Liquefaction countermeasures 【Features】 ● A consistent cylindrical diameter can be expected for any type of soil. ● Three types are set to accommodate construction purposes and conditions: Ø1.5m, Ø2.0m, and Ø2.5m. ● Excellent adhesion to retaining walls and structures. ● Cutting is performed with two intersecting jets, allowing for superior mixing and the creation of high-quality improved bodies. ● Using cement-based hardening materials ensures excellent durability.

[Case Study] Street Bond Stencil Method

[Case Study] Street Bond Stencil Method

The stencil method is a landscaping technique that uses "paper stencils." It is suitable for situations where embossing is not possible and for enhancing the aesthetic appeal of concrete surfaces.

In this document, we have published numerous examples of stencil construction methods. We introduce various projects, including "station platforms," "safety measures at road intersections within residential areas," "pedestrian-vehicle separation safety measures," and "landscape paving work in parks," along with photographs. By selecting pattern designs and determining the colors of the joints and surfaces, it is possible to create the texture of stone or brick paving. In addition to standard patterns, we can also create original stencil patterns. Please feel free to make use of this. [Examples Featured] ■ Landscape painting work for customer walkways at a car dealership ■ Pedestrian road paving and pedestrian-vehicle separation safety measures ■ Landscape painting work for pedestrian-only pathways within residential areas ■ Temporary restoration paving landscape painting work ■ Landscape painting work for sidewalks at a car dealership *For more details, please refer to the PDF document or feel free to contact us.
