Problems solved by technology

However, these devices need to complete the construction of the energy storage device, trigger device and drainage device before building the slope. This patent cannot be implemented for the existing highway slope, so that the existing highway slope cannot achieve rapid drainage and drainage. reinforcement

Abstract

The invention discloses a draining pipe applied to drainage and reinforcement of an existing expressway side slope and a construction method of the draining pipe. The head of the draining pipe is in a flat shovel shape; the draining pipe body is provided with rectangular holes and circular holes, wherein the rectangular holes and the circular holes are triangularly distributed along the longitudinal direction and are distributed at an interval in the same rectilinear direction; at least four holes are uniformly distributed along each circle of the circumferential direction of the draining pipe body; the tail of the draining pipe has one arc section provided with no hole, and the rest arc sections are provided with at least three holes which are uniformly distributed. The construction method of the draining pipe comprises the following steps: (1) taking the flat shovel end of each draining pipe as an inserting end; (2) taking the arc section, provided with no hole, of each draining pipe as a bottom surface; (3) obliquely inserting the flat shovel end of each draining pipe at a gradient of 20% into a stable soil layer of the side slope so as to form rectangular or triangular arrangement at the slope surface. According to the draining pipe disclosed by the invention, the front section of the draining pipe is set in a flat shovel shape, so the draining pipe can be beneficially inserted into the side slope, more convenient and quicker construction can be realized, and the aim of rapid drainage and reinforcement of the side slope is fulfilled.

Description

technical field [0001] The invention belongs to the technical field of slope management and protection, and relates to a drainage pipe used for drainage and reinforcement of existing expressway slopes and a construction method thereof. Background technique [0002] At present, the mileage of expressways in my country exceeds 120,000 kilometers, ranking first in the world. Such a huge highway network poses new challenges to road maintenance. [0003] Continuous heavy rainfall is one of the main causes of highway slope collapse. Continuous heavy rainfall causes the groundwater level of the embankment to rise. On the one hand, the weight of the sliding body increases, and on the other hand, the strength of the soil decreases. Therefore, the safety of the slope The coefficient decreases, and the collapse occurs. Different from traditional slope engineering, once the expressway slope collapses, it needs to be repaired and treated quickly in order to open to traffic and divert t...
