Semi-permeable discharge pipe and its discharging net

Abstract

The present invention discloses a semi-permeable drainage pipe and a related drainage pipe network, and relates to a drainage pipe and a related drainage pipe network. A semi-permeable drainage pipe (10) is composed of an upper semi-pipe for permeability (11) and a lower semi-pipe for non-permeability (12). A structure of the drainage network based on the semi-permeable drainage pipe is described as follows: a drill hole (40) is arranged at a drainage zone (30), the semi-permeable drainage pipe (10) is arranged on the internal wall of the drill hole (40), and a water stop material (20) is arranged between the lower positions of the semi-permeable drainage pipe (10) and the drill hole (40). The present invention only drains water from the drainage zone (30) in a single direction, but does not transfer at other places except for the draining zone (30); reduces the location of the saturated surface of underground water; is applied to the civil engineering, the water conversancy, the transportation, the bridge, the mine, the municipal engineering, the agriculture, the horticulture and other drainage and precipitation fields.

Description

technical field [0001] The invention relates to a drainage pipe and its drainage network, in particular to a semi-permeable drainage pipe and its drainage network, which are suitable for various drainage and precipitation engineering fields such as civil engineering, water conservancy, transportation, bridges, mines, municipal administration, agriculture, and gardens. Background technique [0002] Traditional drainage pipes mainly use drainage technologies such as plastic pipes, steel pipes, drainage mattresses, drainage boards, and drainage prisms. The drainage pipes in these several technologies all face the problem that the leakage water is transmitted while the drainage pipe drains, and the water is easy to flow out from the gap between the outer wall of the drainage pipe and the wall of the borehole, and the drainage effect needs to be improved. [0003] Traditional drainpipes have the following disadvantages: [0004] 1. The traditional drainage pipe is a drainage mea...

AI Technical Summary

Problems solved by technology

[0004] 1. The traditional drainage pipe is a drainage measure and also a leaky pipeline; there is a gap between the drainage pipe and the drainage area, and some pore water will flow along the gap, and the drainage effect is not ideal;

[0005] 2. When the drainage area needs to be unstable seepage, the position of the wetting surface formed after the drainage pipe is inserted is not easy to determine, and the length of the permeable part of the drainage pipe wall (for example: the length of the screen hole and the length of the permeable pipe) is not easy to determine

If the length of the permeable part is too long, part of the water entering the drain will be transferred into the unsaturated area; if the length of the permeable part is too short, the drainage capacity is limited, and the drainage effect is also not good
