Abstract

The invention relates to agricultural land reclamation and can be used in the drainage of wetlands closed drainage. The purpose of the invention is to increase operational reliability. The drainage mouth includes a wellhead pipe 1, mated to the drainage pipe 2 and reinforced in the slope of the collector 3, and a tubular insert 4. The pipe insert 4 is made in the form of a piece of flexible hose. One end of the flexible hose is inserted into the wellhead pipe 1 with the possibility of free movement and deflection in it, and the other end into the pipe 5 of larger diameter fixed on the float 6 freely mounted on the stand 7 with the possibility of axial movement. 2 Il.

Description

The invention relates to agricultural land reclamation and can be used for draining wetlands with closed drainage.

The purpose of the invention is to increase operational reliability.

FIG. 1 shows a drainage mouth, a general view of FIG. 2 - drainage mouth, view after the slope is melted - under it.

The drainage mouth includes an orifice tube t connected to the drainage pipe 2 and reinforced in the collector slope 3 and a tubular insert made in the form of a piece of flexible hose, one end of which is inserted into the wellhead 1 with the possibility of free movement in it and deflection, and the other a larger diameter pipe 5 fixed on the float 6 freely mounted on the guide stand 7 with the possibility of axial movement installed in the channel 8 of the open collector.

Drainage mouth works as follows.

Before the technical pressure of the collector slope 3 remains stable, the water drainage ™ from the drainage pipeline 2 expires and the collector both from the wellhead pipe 1 and pipe 5 on the float 6.

During the operation of the drainage well, the groundwater is wedged out on the slope 3, and most intensively under the wellhead pipe 1, due to the presence of filter dusting of the drainage pipeline 2 initially causes k to sink around the soil beneath it (Fig. 2, block I). After block I creeps in and a niche is formed under the well pipe 1, the soil beneath it (block II, fig. 2) is discharged, and the mouth of the pipe falls asleep

1, the channel 8 of the open collector is constrained and the water level rises in it and together with it the float 6 rises with a pipe 5 fixed on it, into which the end of the flexible hose is inserted. At the same time, the ground collapses from the collector slope, impacts the flexible hose, bends it down. Its ends, having a certain length and free movement in the mouth pipe 1 and pipe 5, mounted on the float 6, mounted on a stand 7 in the channel 8, provide maximum deflection to the bottom of the collector without disconnecting with the mouth pipe 1 and pipe 5. Thus, even after the slope has been melted and the wellhead pipe is completely filled up, the end of the flexible hose L attached to the float 6 remains above the water level in the collector and not filled with soil, as a result of which the water from the drainage pipeline is unobstructed о ensures efficient operation of the drain and its drying action.

Claims (1)

Invention Formula A drainage mouth, including a wellhead pipe associated with the drainage pipe and a tubular insert installed in it for movement and fixation, characterized in that, in order to increase operational reliability, the tubular insert is made in the form of a piece of flexible sleeve inserted into the well pipe at one end with the possibility of free movement in it and deflection, and the other end of the sleeve. is placed in a tube of larger diameter with the possibility of axial movement fixed on the float freely mounted on the just a hundred ke.
