Device for draining and reinforcing the slope of existing expressway and construction method thereof

Abstract

The invention discloses a device for draining and reinforcing the slope of an existing expressway. The device comprises a drain pipe, a plurality of positioning mechanisms, an anchor rod, a pluralityof dredging mechanisms, a baffle plate and a handle, wherein one end of the drain pipe is cylindrical, and the other end of the drain pipe is tabular; a plurality of drain branch pipes are arranged inthe drain pipe; one of the drain branch pipe is provided with a corresponding positioning mechanism; each of the positioning mechanisms comprises two support rods and two sliding blocks; a conical guide block is arranged at the end part of the anchor rod; and the dredging mechanisms are positioned at the other end of the anchor rod. According to the device, the acting force of the anchor rod is utilized to completely strut the drain pipe open, the drain branch pipes which can stretch out are arranged in the drain pipe, and the dredging mechanisms which can wipe the drain pipe are arranged inthe drain pipe, so that the draining speed of ponding in the slope can be greatly increased; and in addition, the dredging mechanisms can clean the interior of the drain pipe regularly, so that soil is prevented from being accumulated in the drain pipe to avoid affecting the water draining effect.

Description

technical field [0001] The invention relates to the technical field of slope management and protection. More specifically, the present invention relates to a drainage pipe used for drainage of existing expressway slopes and a construction method thereof. Background technique [0002] Expressways are high-grade highways. According to the "Technical Standards for Highway Engineering" of the Ministry of Communications of the People's Republic of China, expressways refer to "highways that can adapt to the annual average day and night passenger car traffic volume of more than 25,000 vehicles, are exclusively used for high-speed driving in separate lanes, and all access and exit are controlled." In order to ensure traffic safety, road maintenance of expressways is particularly important, especially for expressways with slopes on both sides. When the moisture content of the slope soil is too high, it will cause unfavorable seepage pressure, hydrodynamic pressure and The key to so...

AI Technical Summary

Problems solved by technology

[0003] The drainage and reinforcement devices of the slope in the prior art need to complete the construction of each component before the slope is built. For the existing highway slopes, the existing drainage and reinforcement devices cannot be installed, and the existing drainage and reinforcement devices cannot be installed. The side slopes of some highways are drained and reinforced
