Currently, in underground pipe installation work, due to the occupation of road surfaces, construction environments of buildings, and advancements in pushing machinery, there is a trend towards longer distances and often involves curved pushing due to road alignments. Consequently, there are demands for smooth excavation and reduced pushing force in the slurry materials. The Mini Long TYPE-II is a highly safe one-component slurry material developed to address these issues. When adjusting properties such as viscosity, it can be easily modified by increasing or decreasing the basic formulation. Additionally, because it contains high water-absorbent resin, it is less likely to be diluted even in water-retaining gravel layers, resulting in a high clogging effect and improved water-stopping capability.

• Special Construction Method

SSD is a thickening agent that replaces the traditionally used CMC (carboxymethyl cellulose) or common powdered thickening agents. Common thickening agents are in powder form, making them very difficult to dissolve; when added all at once, they clump together, and only small amounts can be added at a time. Moreover, they often lack workability. SSD from Hariba Co., Ltd. is in liquid form, so it can be added all at once to water without clumping, and it can be used in small amounts from a poly container, making it very superior in terms of workability and cost-effectiveness.

Sliding SS-II is a two-component solidifying lubricant (plasticizer) used for the construction and burial of attached pipes and underground structures. In underground construction, voids and friction resistance inevitably occur at the contact points between the buried structures and the surrounding ground. If these voids are left unaddressed, it can lead to ground subsidence and significant accidents such as structural damage or road collapses. Sliding SS-II is a two-component solidifying lubricant that fills these voids and reduces friction resistance. Additionally, it requires less usage compared to conventional types, allowing for more efficient use of storage space at the construction site.

The conventional sediment prevention agents (blocking materials) are made from fibers such as sawdust, old paper, and old cloth, which means that even when they are compressed to some extent, their volume and packaging size are large, requiring a wide area for storage on-site. Additionally, during the addition process, since they are added in small amounts, dust disperses, creating issues with the working environment. The solution to this problem is Freewood. Freewood is about one-fifth the size of conventional sediment prevention agents, making it easier to handle and requiring less storage space. 【Features】 ○ Almost no dust generated as a solid ○ Realization of compactness ○ 1 kg cuts for easy mixing ○ Easy to handle ○ Usable in many construction methods *For more details, please contact us or download the catalog.
