Buried type side slope drainage system and construction method thereof

Abstract

The invention provides a buried type side slope drainage system and a construction method thereof. The drainage system comprises a plurality of transverse drainage ditches and a plurality of vertical drainage ditches. The vertical drainage ditches are of drainage structures formed in the manner that after a slope is filled or dug according to a design drawing, drainage pipe pre-buried grooves are formed in the positions, corresponding to the vertical drainage ditches, of all levels of side slopes and platforms, drainage pipes are pre-buried in the drainage pipe pre-buried grooves, and protection structures are built on the upper portions of the drainage pipe pre-buried grooves. A force eliminating platform, an accumulating pond and a water collecting pond are built at the joint of the transverse drainage ditches and the vertical drainage ditches, the force eliminating platform is right opposite to water outlets of the drainage pipes in the upper level side slope, and water is led to the collecting pond and the water collecting pond in sequence and then is led into the vertical drainage pipes in the lower level side slope through the water collecting pond. According to the buried type side slope drainage system and the construction method, the constructed drainage system is buried underground, the continuity and attractiveness of side slope protection are not affected, the drainage pipes cannot be damaged by exposing and grinding, the drainage pipes are prevented from being blocked through a multi-layer filtering method, the drainage smoothness is improved, and maintaining cost is reduced.

Description

technical field [0001] The patent of the present invention relates to the field of slope drainage, and specifically relates to a buried slope drainage system and a construction method thereof which use buried drainage pipes to connect two-stage platform drainage ditches as drainage channels. Background technique [0002] An important link in slope design is the design of drainage system. The impact of water on slope stability is great, sometimes even catastrophic. If the drainage measures are not perfect, the slope may become unstable, so a reasonable and effective drainage system must be adopted. The common drainage system generally adopts the combination of horizontal drainage ditch and vertical drainage ditch. The horizontal drainage ditch is generally built as a platform row between the two slopes, and the vertical drainage ditch connects two adjacent horizontal drainage ditch longitudinally. The vertical drainage ditch and the horizontal drainage ditch intersect to for...

Problems solved by technology

[0004] In addition, there are also the following defects in the methods of building drainage ditches on the slope and digging trenches to build drainage ditches: 1. Both of the two masonry methods need to use a large amount of materials such as concrete or chip stones, and a large amount of The cost of these materials is high, which increases the cost of masonry; 2. If a small displacement occurs on the slope, when the local soil on the slope is soaked and loosened, it will easily lead to the collapse of the drainage ditch; 3. Due to the drainage The ditch is built on the surface of the slope, and its drainage ditch is open, and it is easy to fall into some soil or other sundries, which will cause the drainage ditch to be blocked, resulting in insufficient drainage, and the ditches are all built on the slope surface. It will be more troublesome to clean up the waste in the ditch
