Embodiment Construction

[0009] In Fig. 1, the gap water collection permeable drainage ditch, the cover plates (2-1), (2-2) are limited by the supporting round steel columns (3-1), (3-2), and the back is vertical, A strip-shaped water inlet gap is formed, the top surface is horizontal, and the gap width H=150-200mm. Ditch cover plate (2-1), (2-2) bottom and limit angle steel (4) are welded firmly, fall on the ditch body (1), ditch body (1) and ditch cover plate (2-1), ( 2-2) Consists of unit components with a length of 1m. A plurality of unit components are combined to form an overall horizontal long ditch. The ditch body (1) is made of resin concrete with a U-shaped section. Both sides of the ditch wall are opening areas (5), the opening diameter is φ10-15mm, and the opening rate is 1.5-4.0%. There are 2 reinforcement bars (6) built-in at the foot of the ditch body. When the crevice water-collecting permeable drainage ditch is buried, the paving ground (13) and the leveling layer (12) are pressed...

Abstract

The invention provides a gap water collection permeation-type drainage ditch, which mainly comprises a cover plate and a ditch body. Two strips of L-shaped non-equilateral angle steel of the cover plate stand back to back, forming a 150-200 millimeters of vertical water inlet gap with a flat straight top; the cover plate is positioned on the ditch body of the drainage ditch; the ditch body and the cover plate are both made into unit components with the length of one meter; a plurality of unit components are combined into a horizontal long ditch; the ditch body is made from resin concrete; thecross section of the ditch body is in a U shape; and two sides of the ditch body are configured as opening areas. When the gap water collection permeation-type drainage ditch is embedded, pavement ground and a leveling course are pressed on the cover plate of the drainage ditch, and the side surfaces of the drainage ditch separate the ditch body from pervious concrete by use of pervious earthworkcloth. In rainy days, a shallow rainwater layer is formed on a square; rainwater flows into the drainage ditch along water collection gaps; part of the rainwater permeates underground through openings on the sidewalls of the drainage ditch so as to be conserved as groundwater; and the redundant rainwater is discharged from the drainage ditch so as to be recycled.

Description

Technical field [0001] The invention relates to the technical field of rainwater utilization, and relates to a drainage ditch for collecting, infiltrating, utilizing and transporting rainwater on the ground of a square. Background technique [0002] Rainfall on large areas of hardened ground such as squares usually flows into the rainwater outlets evenly distributed in the square and is drained through underground pipes. This known drainage method does not have the function of making rainwater seep into the ground, and rainwater flows away as a resource in vain, and due to the water collection needs of the rainwater outlet, the square presents a concave area sloped towards the rainwater outlet. The effect that affects the use of the square. Contents of the invention [0003] In order to overcome the functional defects of the existing square drainage system, the present invention provides a crevice water-collecting permeable drainage ditch, which can uniformly collect rain...
