Description

Curved pipe side slope drainage system

Technical Field

The utility model relates to a bent venturi tube side slope drainage system.

Background

The current drainage mode of the road cutting slope is mainly gravity drainage, and the drainage pipe is a more popularized and applied mode in cutting slope drainage and mainly comprises a horizontal drainage pipe and an oblique drainage pipe; the drain pipe utilizes the top and the side interval infiltration hole of drain pipe to collect groundwater, then discharges the groundwater in the side slope under the action of gravity, lays the drain pipe in the side slope and can discharge the groundwater in the slope, can effectively improve the stability of side slope. However, drains also have some limitations: (1) at present, the drainage pipe mainly adopts a perforated PVC plastic pipe, but the application effect of the previous engineering example shows that the PVC plastic pipe has low strength, quick aging and poor durability and cannot bear the complex deformation of a side slope; (2) although the outer part of the drain pipe is generally wrapped with a layer of permeable geotextile to reduce or prevent the soil from blocking the water seepage holes on the drain pipe, the permeable geotextile on the outer part of the drain pipe is easily blocked by the soil in the later natural drainage process, so that the underground water cannot enter the drain pipe through the water seepage holes to cause the drainage function of the drain pipe to be invalid; (3) under the influence of the terrain of the side slope and the construction process, the drainage pipe has higher requirement on drilling in construction, the length of the drainage pipe driven into a rock-soil body is limited, the drainage can be carried out only aiming at the local side slope body, and the underground water in the side slope body at a deeper position and a farther position cannot be drained; (4) the pipe diameter of the drain pipe adopted at present is mainly 75 mm-150 mm, and the requirement of timely draining the underground water cannot be met when the amount of the underground water is large. In addition, although different drainage projects and drainage pipes are combined (such as a water collecting well and a drainage pipe) to reduce underground water in a slope body at a deeper position and a farther position, the underground water is difficult to be applied in practice due to complicated construction and difficult connection (such as inaccurate positioning when the combined position of the water collecting well and the drainage pipe is connected); it is therefore desirable to design a new drainage system to address the problems currently encountered.
