Collection method and construction technology for pds zero-gradient protection siphon drainage

Abstract

The invention discloses a collection method and a construction technology for pds zero-gradient protection siphon drainage. The collection method comprises: soil infiltration water continuously flowing to a siphon drainage channel through a macromolecule protection drainage abnormal-shaped sheet, water in the siphon drainage channel rapidly collecting on a water outlet, through a pipe line reducing diameter method, the water outlet making a siphon straight pipe form full flow, so as to form siphon, and the water entering an observation well and a water-collecting well in sequence, and finally the water being reused. The construction technology is that laying an adhesive tape, the siphon drainage channel, the macromolecule protection drainage abnormal-shaped sheet, a reducer pipe, the observation well and the water-collecting well in sequence. The collection method and construction technology for siphon drainage do not need to obtain gradient, and waterproof processing is not needed, and a principle of siphon is used, and original passive drainage is changed to active drainage, so as to effectively solve problems of an existing drainage structure that drainage is not thorough, water leaks, and vegetation is damaged. The method and the technology can reduce cost and construction period, effectively prolong life of buildings, and collected water can be reused.

Description

technical field [0001] The invention relates to a drainage collection method and construction technology, in particular to a pds zero-slope protection siphon drainage collection method and construction technology. Background technique [0002] In the prior art, in the greening and drainage systems of three-dimensional garages or other house structures, drainage boards and waterproof structures are the most commonly used. Drainage boards are generally used for planting roofs. The existing drainage boards form solid or cup-shaped protrusions on the polymer sheet. The mouth of the cup-shaped protrusions is in the opposite direction of the protrusions. The protrusions are generally upward. The space in between constitutes the drainage channel. When the protrusions are down, holes are punched between the protrusions, and water passes through the holes and flows away from the spaces between the protrusions. The drainage system using drainage boards in the current technology is s...

Problems solved by technology

[0004] Purpose of the invention: The purpose of the present invention is to solve the deficiencies in the prior art, to provide a method that does not need to find a slope, and does not need to be waterproofed. The principle of siphon is changed from the original passive drainage to active drainage, thus effectively solving the existing problem There are situations such as incomplete drainage of drainage structures, water leakage, damage to vegetation, building structures, etc., and the present invention can reduce costs and construction periods, effectively prolong the life of buildings, and the collected water can be reused.
