Description

Nodular cast iron integral drainage ditch

Technical Field

The utility model relates to a drainage technique especially relates to the escape canal.

Background

Finished drainage ditches sold in the market at present mainly comprise resin concrete, and the finished drainage ditches are mainly applied to occasions such as city streets, residential squares, parking lots, parks and the like. This kind of finished product escape canal comprises two parts: namely a resin concrete ditch body and a drainage cover plate. The material of the drainage cover plate can be resin concrete material, cast iron material, carbon steel galvanized material or stainless steel material according to the use place. This type of drain can be used only for longitudinal roads on express lanes because the cover and the gutter body are two parts independent of each other. When the cover is used on a lateral road, the cover and the gutter are likely to be separated from each other due to excessive impact force, and cause noise. And the resin concrete ditch body is more easily impacted and cracked by the influence of transportation jolts in the transportation process.

At present, the design of circular nodular cast iron integral drainage ditch has also appeared, but because the cast iron drainage ditch is inside not smooth, and the coefficient of friction of iron and water is far greater than the coefficient of friction of resin concrete and water, so water velocity of flow is slower in this circular nodular cast iron integral drainage ditch, leads to the drainage smoothly easily and leads to the fact road ponding.

Disclosure of Invention

The utility model aims to solve the technical problem that a spheroidal graphite cast iron integral type escape canal that bearing capacity is strong, can quick drainage is provided.

The embodiment of the utility model provides a nodular cast iron integral type escape canal, including ditch somatic part and top cap portion, the material of ditch somatic part and top cap portion is nodular cast iron, and ditch somatic part and top cap portion are through casting integrated into one piece, and define a drainage channel jointly; it is characterized in that the section of the drainage channel is V-shaped, and the bottom of the V-shaped section is in circular arc transition.

The integrated drainage ditch provided by the embodiment of the utility model is made of nodular cast iron, and the ditch body and the roof of the drainage ditch are integrated, and are directly and integrally cast and formed by casting and core-making processes, so that the problem that the resin concrete drainage ditch has low bearing capacity and cannot be used for drainage of a transverse express way is solved; in addition, the cross sectional shape of the drainage channel of this integral type escape canal is the V-arrangement, and the bottom in V-arrangement cross section is the circular arc transition, is circular shape nodular cast iron integral type escape canal with the cross sectional shape and compares, and water flow velocity is faster in the escape canal, can the drainage fast.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

Please refer to fig. 1 to 7. According to the utility model discloses a nodular cast iron integral type escape canal 100 of an embodiment includes ditch somatic part 1 and top cap portion 2.

The groove body part 1 and the top cover part 2 are made of nodular cast iron, the groove body part 1 and the top cover part 2 are integrally formed through casting, a drainage channel 3 is defined together, the cross section of the drainage channel 3 is V-shaped, and the bottom 3a of the V-shaped cross section is in circular arc transition.

The utility model discloses drainage channel's in nodular cast iron integral type escape canal cross sectional shape is the V-arrangement, is the circular shape nodular cast iron integral type escape canal with cross sectional shape and compares, under the same circumstances of rainfall, has increased the degree of depth of ponding through reducing bottom drainage sectional area, and then has increased ponding pressure for the velocity of flow has finally reached the purpose of quick drainage, has avoided leading to the road ponding problem that the drainage is not smooth to cause because of rivers flow rate is slower in the escape canal.

Optionally, the ductile cast iron integrated drainage ditch of the embodiment is made of ductile cast iron with the mark of QT500-7, and the compressive strength meets the national standard D400.

The top lid portion 2 is opened with a plurality of water discharge ports 21 for allowing water flow to flow into the water discharge passage 3. Two ends of the groove body part 1 are respectively provided with a pair of supporting feet 11, and each pair of supporting feet 11 are respectively arranged at two sides of the groove body part 1. Each support leg 11 has a foot sole portion 111 extending in the horizontal direction.

Please refer to fig. 8 and 9. In this embodiment, the one end of the groove body 1 is provided with the insertion part 1a that extends to the outside protrusion, and the other end of the groove body 1 is provided with the slot part 1b that matches with the insertion part 1a in an insertion manner, and through inserting the insertion part 1a of two nodular cast iron integrated drainage ditches 100 into the slot part 1b, the splicing of two nodular cast iron integrated drainage ditches 100 can be realized. If a plurality of the spheroidal graphite cast iron integrated drainage ditches 100 are connected end to end, a drainage system can be formed.
