Problems solved by technology

These existing methods have the following deficiencies: high requirements for building materials and large transportation volume of materials; high requirements for construction machinery and complicated construction methods; The surface is not suitable for greening, and the slope is not in harmony with the surrounding environment after treatment; the support structure has a greater impact on the groundwater; the impact of excavation or drilling vibration is too large, and the stability of the slope is due to the large-scale excavation or drilling vibration, etc. Further reduction due to additional construction factors may cause slope sliding or accelerate its sliding, resulting in greater damage and loss

specific Embodiment approach

[0024] figure 1 , 2 Shown, a kind of specific embodiment of the present invention is:

[0025] A method for protecting and treating rock / soil slopes. The method is: excavate a groove for building a support wall along the sliding direction of the slope; 3m, the depth is 0.5-1m embedded in the bedrock with bearing capacity in the lower part of the slope or exceeds the slope sliding surface 9, the length is from the foot of the slope to the top 11 beyond the slope sliding body; the net distance between the support wall 1 and the wall is 2-2 8m.

[0026] When excavating trenches, the same trench shall be excavated in sections of 6 to 10 meters, and the excavation of different trenches shall be carried out at least one trench apart; after the excavation is completed, the sides and bottom of the trench shall remain open naturally. Excavate the surface without any smoothing and troweling treatment, and start to build the longitudinal support wall 1 within 24 hours.

Abstract

A fencing method for sloping field is as: grove along the sloping field and build supporting walls in it. The wall is 1-3m in width, 0.5-1m in depth into the base rock, the same height of the field foot to top. The distance between walls is 2-8m.

Description

technical field [0001] The invention relates to a method for protecting and treating rock / soil slopes. Background technique [0002] Slope protection and management is an important issue in mountain road and railway construction, water conservancy and hydropower development and urban construction. Although the country and localities invest huge manpower and material resources every year to manage it, the traffic obstruction and interruption caused by the slope accident, the river blockage, the harm to the reservoir area and the city / country are still huge, and the losses are still huge. Very huge. With the rapid development of my country's overall construction of a well-off society, especially with the vigorous rise of the western development, the seriousness of the slope problem will inevitably become more prominent. Therefore, slope prevention and control work is not only indispensable, but also becomes more important. [0003] Slopes, especially cohesive soil slopes th...
