Landslide construction for underground pipelines

 

The invention relates to the construction, namely, devices, designed to reduce landslide pressure on pipelines located on landslide slopes. Landslide construction for underground pipelines includes located at the apex of the angle of wrap of the movable cutting element wing. What's new is that the movable cutting element wing is made in the form of a perforated tube, equipped with a pressure sensor ground and communicated with a reservoir for fluid, and the pressure sensor ground also communicated with a reservoir for fluid, and an underground pipeline recorded landslide in the array by means of anchoring. Technical result provided by the invention is to improve reliability and reduce construction and operating costs due to the possibility of changes in the strength characteristics of soil landslide array. 1 Il.

The invention relates to the construction, namely, devices, designed to reduce landslide pressure on pipelines located on landslide slopes.

Known invention (see patent RU 2162123 C2, E 02 D 31/08, F 16 L 1/028, E 02 D 29/00, 20.01.2001), by which the rights of construction elements in the form of a straight or l-shaped, installed top corner moving towards the ground, retaining walls, anchor held by cords, with anchor strands upper end connected to the retaining wall, and the bottom with stable soils.

The closest in technical essence is the patent RU 2186907 C1, E 02 D 31/08, 29/00, F 16 L 1/028, 10.08.2002 for protection of underground pipelines before the pipe at the apex of the angle of wrap, arrange the cutting element in the form of inextensible filaments, equipped with a rotation mechanism, made in the form of rings on the bearing type, attached to the pipeline, while the rings are metal rods installed on the cutting element and the wing set for the possibility of moving the cutting element depending on the direction of the landslide mass.

The disadvantage of the first technical solution is the need of the construction of bored piles and concrete retaining walls. When the device is l-shaped retaining wall design works in terms of flow by a landslide, but the fixed position of the walls has a negative impact when the angle of the direction of movement of the landslide mass.

The disadvantage of the second technical solution is a passive operation of the cutting elementtree is to increase reliability and reduce construction and operating costs due to the possibility of exposure of the cutting element on the landslide mass to change the strength characteristics of soils during operation, and fixing the position of the pipeline in space (in the body of landslide array).

The problem is solved due to the fact that in landslide construction for underground pipelines, including situated at the apex of the angle of wrap of the movable cutting element, the latter is in the form of a perforated tube, equipped with a pressure sensor ground and communicated with a reservoir for fluid, and the pressure sensor ground also communicated with the reservoir for fluid, and an underground pipeline recorded landslide in the array by means of anchoring.

Technical result provided by the invention is to improve reliability and reduce construction and operating costs due to the possibility of changes in the strength characteristics of soil landslide array.

The novelty of the claimed proposal due to the fact that in comparison with the known technical solutions increases the reliability of pipelines through dangerous areas with moving the cutting element with the wing, made in the form of a perforated tube, equipped with a pressure sensor ground and communicated with a reservoir for fluid, and the pressure sensor ground also situations fixtures.

The invention is illustrated by the drawing, which shows a landslide facility for underground piping, side view.

Landslide facility for underground piping contains mounted on the pipe 1 and located at the apex of the angle of wrap of the movable cutting element wing 2, made in the form of a perforated tube, which, under the control of the pressure sensor ground 3, is supplied from the tank 4 fluid, reducing the strength characteristics of the soil landslide array 5, and to exclude the effect of “ascent” (extrusion on the surface of the pipe 1 is fixed by anchors 6 in the body of landslide array 5.

Landslide facility for underground piping works as follows: when moving ground landslide 5 creates pressure on the pressure sensor ground 3, the sensor sends a command, which from the tank 4 is fed into the perforated tube of the cutting element fluid to reduce the strength characteristics of the soil landslide array, liquid zamachivaem approaching the ground, resulting in falling strength characteristics of the landslide mass, 5 and decreases landslide pressure. In the zda. If the process flow with passive cutting element with the wing occurs according to the scheme shift on the prepared surface, with the active (soak-off) cutting element with the wing mechanism of flow will shift prepared wetted surface.

The construction of landslide protection works performed in the following sequence: off trench 7, arranged anchoring 6, along the trench is located in the tubing 1 on a set of active cutting element wing 2, associated with the container for the liquid 4, the pressure sensor 3, lowering the pipeline into the trench 7, fixed on the anchor mounts 6 and go to sleep with the soft soil backfill 8.
