Abstract

This invention relates to land reclamation. The purpose of the invention is to increase the efficiency and reliability of work. The drainage well includes a housing 1 and a sump 5. The housing 1 has a base 2, a cover 3 and is mounted on supporting elements 4. The sump 5 is made with perforations 8 and is located outside the housing 1 in the filtering bed 6. The sump 5 matches the base 2 of housing 1 and connected to the drainage pipe 7. Installing the housing 1 on the supporting elements 4 and the location of the sump 5 outside the housing 1 below the freezing depth eliminates the impact on the mating site of the sump 5 with the drainage pipe 7 of the tangential frost heave forces in and cracks in the pipeline 7. 1 yl.

Description

The invention relates to the field of amelioration and can be used as a manhole on closed drainage systems, surface water absorbers, control wells on closed drying-humidifying or irrigating systems in heaving soils.

The purpose of the invention is to increase the efficiency and reliability of work. I The drawing shows the proposed device.

The drainage well consists of a body 1 having a base 2 and a cover 3 mounted on the supporting elements 4, a settling tank 5 placed in a filter bed 6, a drainage pipe 7 laid between the supporting elements 4 and connected to the settling basin 5 which is provided with a perforation 8. The settling tank 5. is located outside the housing 1 and is associated with its base 2.

In the dehumidification mode, the well is operated by a 3 ohm eater.

Water collected from the drained territory passes through the drain pipe 7 to the sump 5 and then through the pipeline 7 to the water intake network (not shown), and the water from the ground around the well is drained through the filter bed.

6 and perforation 8 in the sump 5. 1 -; . The advantage of the proposed

the well is that the installation of the housing 1 on the supporting elements 4, and the sump 5, provided with perforation 8, regardless of the housing of the well 1, completely below the freezing depth eliminates the effect on the mass

Claims (1)

This interface of the sump 5 with the pipeline 7 to the tangential forces of the frost heave significantly reduces the effect of gravity, and this reduces the formation of cracks and gaps in the pipeline 7 and in the places of its mating with the sump 5 and reduces the removal of the liquefied soil into the drainage system reliability of the land reclamation system Invention Formula A drainage well, including a housing with a base and a lid, placed in a filter bed and coupled with a drainage pipeline, and a sump with perforated walls, communicated with the housing, in order to improve the efficiency and reliability of operation, the well is equipped with supporting elements, and the drainage pipe is connected to the sump, which is located outside the body in the filtering bed and is adjacent to its base.
