Novel plastic blind drain

Abstract

The invention relates to a novel plastic blind drain. A blind drain main body is lapped by modified polypropylene and comprises two concentrical cylinders, wherein reinforcing ribs are arranged on an external wall of the inner cylinder and an internal wall of the outer cylinder; and the internal surfaces and external surfaces of the inner cylinders and the outer cylinders are wrapped with geotechnical cloth. The blind drain comprises the two concentrical cylinders, and the reinforcing ribs are arranged on the external wall of the inner cylinder and the internal wall of the outer cylinder, so that the physical strength of the blind drain is improved, and the service life of the blind drain is prolonged. As the internal surfaces and the external surfaces of the inner cylinder and the outer cylinder are wrapped with the geotechnical cloth, broken stone in a roadbed can be filtered, and clear water can enter the blind drain to be drained.

Description

technical field [0001] The invention relates to an underground drainage channel arranged in a roadbed or foundation, in particular to a new type of plastic blind ditch. Background technique [0002] Plastic blind ditch is a device for filtering sewage. The existing plastic blind ditch includes a frame and a geotextile arranged outside the frame. The sewage in this structure flows into the frame and is filtered into clear water through the geotextile; the blind ditch of this structure uses After a period of time, shrinkage will occur due to the strength of the frame, resulting in low water filtration efficiency in the blind ditch. Contents of the invention [0003] In order to solve the above problems, the present invention provides a novel plastic blind ditch with simple structure, low production cost and high strength. [0004] The technical solution of the present invention is: the main body of the blind ditch is made of modified polypropylene, and the main body of the ...
