Design method for reconstructing side slope by uniformly covering soil

Abstract

The invention discloses a design method for reconstructing a side slope by uniformly covering soil, which is suitable for the ecological restoration of mining wasteland. The method comprises the steps of firstly, designing reconstruction slope information according to an expected effect, and then measuring the width j of construction equipment and the maximum working distance i of the equipment, wherein the reconstruction slope information comprises a target soil covering thickness f and a target slope alpha; then determining the thickness g of a matrix layer of the internal foundation side slope of the reconstructed side slope, and extending and constructing a working platform which is matched with the width j of the construction machinery and is a in width at the highest position of the internal foundation side slope; and determining the bottom surface length d of the inclined slope surface of the foundation slope, the slope bottom length e of the foundation slope and the bottom surface length c of the inclined slope surface of the soil covering layer according to the target soil covering thickness f and the target slope alpha of the reconstructed slope and the maximum working distance i of the construction machine so as to ensure that the construction machine can complete slope surface reconstruction construction on the slope reconstruction working platform. The method is simple in steps, low in learning threshold, suitable for slope reconstruction by equipment and convenient to popularize.

Description

technical field [0001] The invention relates to a reconstruction side slope design method, in particular to a reconstruction side slope design method with uniform soil covering used in the ecological restoration of abandoned mine land. Background technique [0002] During the mining process, whether it is open-pit mining or underground mining, the original terrain has been greatly changed. In order to restore the original landscape of the mining area, reconstruction of the terrain through engineering measures is currently the main method. Taking into account the use of the restored land surface, soil and water conservation, and the effect of vegetation reconstruction, building a stepped platform with a certain slope is the main terrain reconstruction method. [0003] Spreading different types of soil by layering is the main way to build a platform. For example, the patent of a protection method for scattered soil slopes in cold regions (CN201410127462.X) proposes the use o...

Problems solved by technology

However, in the actual laying process, since the length of the slope exceeds the working range of the excavator, it is difficult for the excavator to handle all the slopes in the process of filling and compacting, and the soil layer at the bottom of the slope is often thicker, while the soil layer at the top of the slope is thicker. Thin phenomenon

Furthermore, the uneven thickness of the soil layer on the slope will also limit the growth of reconstructed vegetation, thereby affecting the overall effect of ecological restoration in the mining area

[0004] The determination of slope parameters needs to comprehensively consider parameters such as the size of the excavator and the terrain reconstruction target, so it is necessary to control key parameters such as soil thickness, slope length, and platform width during the covering process, but no related methods have been found in the prior art
