Abstract

FIELD: construction.

SUBSTANCE: method of constructing a drain outlet structure refers to construction and hydrotechnical melioration and can be used for drainage of underground parts of buildings and constructions, cottage and cottage areas, roads, slopes of excavations, agricultural fields. Object of the invention is to improve the environmental safety of the environment. Task is achieved due to the fact, that at the water level of the water intake on the bank of the bank a digging trench is dug out, which is filled with granite rubble 2 with simultaneous installation of a water intake well 3 with a lid and without a bottom, and below it are laid perforated drainage pipes 4 in the geotextile winding, both along the waste ditch, and across it, and the outlet of drainage pipes on the surface of the slope is excluded. Further, between water intake 3 and additionally installed drainage 5 wells, a trench is dug out, at the bottom of which the sand preparation 6 falls and outlet pipe 7 is laid, coupled to collecting pipe 8 through drainage pit 5.

EFFECT: quality of drainage water discharged into the water intake increases.

Description

The invention relates to the construction and irrigation and drainage and can be used to drain the underground parts of buildings and structures, summer cottages, roads, slopes of excavations, agricultural fields.

A known method of construction of the mouth of the drainage system, including the device of the collector pipe, mating with the trays [1].

The disadvantage of this method is that the water from the drainage system is directly discharged into streams (rivers) and reservoirs (lakes, reservoirs). The discharge of drainage water directly into the water intake pollutes them; according to the water code of the Russian Federation, this is not permissible.

There is also known a method of construction of the mouth of the drainage system, comprising a device at the mouth of the collector pipe of reinforced concrete and other heads [2].

The disadvantage of this method is the violation of environmental safety due to the fact that the water from the drainage system is directly drained into streams (rivers) and reservoirs (lakes, reservoirs) and pollutes them.

The objective of the invention is to improve the environmental safety of the environment.

The technical result achieved by the invention is to improve the quality of drainage water discharged into the water intake.

The technical result is achieved due to the fact that, at the water level of the water intake on the bank slope, a discharge trench is dug, which is filled with granite gravel with simultaneous installation of the water intake well with a cover and without a bottom, and below it, perforated drainage pipes are laid in a geotextile winding, as along the discharge ditch, and across, the outlet of the drainage pipes to the surface of the slope is excluded, then a trench is dug between the water intake and the additionally mounted drainage wells, on the bottom of which the dump sand preparation and stack wellhead pipe, which is interfaced with the collector pipe through the drainage well.

The invention is illustrated by drawings.

In FIG. 1 shows a section of a wellhead structure in a vertical plane.

In FIG. 2 shows a discharge trench in a plan.

Drainage includes: a discharge trench 1, with granite crushed stone 2, a water intake well 3, perforated drainage pipes 4, a drainage well 5, sand preparation 6, a wellhead pipe 7, interfaced with a collecting pipe 8 through a drainage well 5.

An example of a specific implementation of the method of construction of the wellhead structure, which consists in the following

At the water level of the water intake at the bank slope, a dumping trench 1 is dug out, which is filled with granite crushed stone 2, with the simultaneous installation of a water intake well 3 with and without a cover, and below it, perforated drainage pipes 4 are laid in a geotextile winding both along the drainage ditch and across moreover, the exit of drainage pipes to the surface of the slope is excluded, then a trench is dug out between the water intake well 3 and the additionally mounted drainage well 5, on the bottom of which a sand preparation 6 is dumped and imposes uphole pipe 7, which mates with a collecting pipe 8 through the drainage well 5.

findings

The proposed method will improve the quality of drainage water discharged into the water intake, by reducing the flow rate of water in the crushed stone sprinkling, as this will cause suspended particles to precipitate. In addition, over time, green algae form on the surface of individual fractions of crushed stone, which, absorbing substances dissolved in water, purify it.

Claims (1)

A method of constructing a mouth of a drainage system, including a collector pipe device, characterized in that a discharge trench is dug out at the water level of the water intake at the bank slope, which is filled with granite crushed stone, at the same time, a water intake well with a cover and without a bottom is mounted, and below it along the waste trench and perforated drainage pipes are laid across it in a geotextile winding, then a trench is dug between the water intake well and the additionally mounted drainage well, to the bottom of which Paiute sand preparation and put wellhead pipe, which is associated with a collecting pipe through the drain well.
