JPS6042129Y2 - U-shaped groove block for water leakage prevention - Google Patents

Description

[Detailed description of the invention] Conventionally, U-shaped groove blocks have been often used as channel materials for agricultural canals, roads, and factory drainage canals, but when connecting U-shaped grooves, the S Butt the parts together and apply concrete, mortar, etc. to the joint, or
Methods have been developed to prevent water leakage from joints by tightening them with bolts, etc., but all of these methods require various complicated steps, materials, and a large amount of labor and time, resulting in inefficiency and cost. Along with this, concrete and mortar become unsuitable for long-term use due to the passage of time and shock vibrations, such as cracks in joints and corrosion of bolts, and defects such as lack of durability and easy water leakage. was there.

However, the purpose of this proposal is to eliminate the above-mentioned drawbacks, and one end of the U-shaped groove block has the outer periphery of the base end, excluding the projecting edges on the left and right sides of the upper end and the inner periphery. Cut the appropriate width, and the other end has notches on the left and right sides of the upper end, and grooves into which the inner peripheral edge fits. When joining and connecting, insert the inner peripheral edge into the groove on the other side. polymerize and fit together,
By an extremely simple operation for fitting the V-shaped protrusion on the inner peripheral edge into the V-shaped notch, it is possible to easily, quickly and accurately join and connect at the work site without requiring any special skill or labor. Moreover, unlike the conventional method in which the ends are butted and connected, the outer periphery of the inner periphery is overlapped with the upper surface of the outer periphery of the groove on the other side, and the inner periphery is fitted and connected to the groove. Therefore, there is absolutely no risk of water leaking from the joint, and by applying a waterproof adhesive such as synthetic resin liquid or rubber glue to the joint between the inner peripheral edge and the groove, the adhesive strength is extremely high. There is absolutely no fear of separation even when subjected to strong vibration shock.Furthermore, by filling the hollow holes on the inner periphery and the hollow holes in the grooves with concrete and mortar and bonding them together, the bond is further strengthened. It increases adhesive strength, has a remarkable effect on water leakage prevention and durability, and prevents water from leaking from joints, causing damage to plants in waterways, or causing damage to humans and livestock due to toxic wastewater. It is possible to completely remove defects and construct a safe and stable waterway, and during production, it can be easily repaired by using a partially improved formwork for concrete U-shaped grooves. As shown in FIGS. 1 to 4, the cross-sectional U-shaped groove block A will be described below with reference to the drawings. At one longitudinal end of the body, except for the protruding edges 1 provided on the left and right sides of the upper end and the inner circumferential edge 2, the outer circumferential edge 4 of the base end is cut off to an appropriate width,
A hollow hole 5 is bored in the front end of the inner circumferential edge 2, a V-shaped protrusion 6 is provided on the side, and a protrusion 1 is provided on the left and right sides of the upper end on the other side.
A notch 7 that fits into the inner peripheral edge 2 and a groove 8 that fits into the inner peripheral edge 2 are formed, and a hollow hole 9 is formed at the end of the groove 8 at a position symmetrical to the hollow hole 5 of the inner peripheral edge 2. A V-shaped cut 10 is made on the side.
A waterproof adhesive 11 such as synthetic resin liquid or rubber glue is applied around the groove 8 of the inner peripheral edge 2, and the hollow holes 5 and 9 are filled with concrete or mortar 3 to make the inner peripheral edge 2 recessed. U for water leakage prevention, characterized by fitting into groove 8 and joining and connecting.
It is a groove block.

By configuring the present invention as described above, when joining and connecting U-shaped grooves, the left and right protruding edges 1 provided at the upper end of one side end are placed in the notch part 7 of the other side end, and the inner circumferential edge 2 is connected to the groove groove. In particular, fitting the V-shaped notch 10 of the groove 8 and the V-shaped protrusion 6 of the inner peripheral edge 2 requires no special skill or special effort. In addition, when fitting the inner peripheral edge 2 into the groove 8, the inner peripheral edge 2 is placed on the upper surface of the outer peripheral edge 4 of the groove 8.
Since the outer peripheral edges 4 of the parts are overlapped and both ends are joined and connected on the upper surface of the outer peripheral edge 4, it is possible to completely prevent separation from the joint, and also to prevent the inner peripheral edge 2 and the groove 8 from coming apart. A waterproof adhesive 11 such as synthetic resin liquid or rubber glue is applied to the joint surface, and concrete or mortar 3 is applied to the hollow holes 5 and 9.
By filling and joining together, the adhesive strength is extremely high, and it has a remarkable effect on separation and separation, and there is absolutely no fear of water leakage, which inhibits plant growth due to water leakage from conventional channel materials. It is possible to completely remove defects such as withering or causing great damage to humans and livestock due to toxic wastewater, and to ensure the construction of safe waterways without the risk of leakage, and transport and storage. In addition, when manufacturing, it is possible to use a formwork that is a partially improved formwork for forming concrete U-shaped grooves, so it can be manufactured efficiently and inexpensively, and is suitable for mass production. This is a device with many distinctive effects.
