Description

A test device for ecological rock and soil mechanics slope protection under simulated rainfall conditions

technical field

The invention belongs to the technical field of rock-soil mechanics slope protection test, in particular to an ecological rock-soil mechanics slope protection test device under simulated rainfall conditions.

Background technique

Slope protection refers to the general designation of various paving and planting on the slope to prevent the slope from being scoured. In the river section where the bridge site is located, the concave bank of the river bank is washed by the water flow year by year, which will cause the river bank to collapse continuously. In order to protect the safety of bridges and embankments, protective buildings must be built on concave banks. In addition, when bridges cause changes in the direction of river water flow, scouring the river bank and endangering farmland and villages and towns, protective buildings must also be built on the river bank.

According to the function of slope protection, it can be roughly divided into two types: (1) slope protection works that are only anti-weathering and anti-erosion, and the protection works do not bear lateral soil pressure, such as sprayed concrete slope protection, lattice frame vegetation slope protection , Vegetative slope protection, etc. all belong to this category, and are only suitable for gentle and stable slopes without the risk of sliding. (2) Soil retaining and slope protection that provides anti-sliding force.

Soil erosion is caused by the damage and loss of water and soil resources and land productivity, which causes huge damage to the ecological environment, especially for slopes, which reduces the stability of slopes and causes serious geological disasters such as landslides, landslides, and debris flows. Cause serious consequences, rainfall is the biggest impact on soil erosion, through the ecological rock mechanics slope protection test under simulated rainfall conditions, to better prevent soil erosion.

In the prior art, under the condition of simulating rainfall, in the test about the influence of slope protection angle on the ability of slope protection to withstand rain erosion, it is difficult to accurately provide a test control group with different angles, because the accuracy of the control group is not high, It has a great influence on the accuracy of the test results.
