Construction Technology of Excavation Excavation in Mountains Near Residential Areas

Abstract

The invention discloses a construction technique for excavating dangers from a mountain near a residential area, which includes the following steps: S1, stake out; S2, make multiple parallel lines from the red line on the side near the residential area to the side of the mountain; S3, from the top to the Under excavation, excavation shall be carried out gradually in layers from the middle to both sides. When constructing each layer, a trench shall be excavated by directional blasting along the line or mechanical cutting, and the raised part near the residential area shall be excavated. It is defined as the rock in the A-line area, the lower groove in the middle is defined as the rock in the C-line area, and the side of the mountain is defined as the rock in the B-line area; S4, after excavating to the set depth in the C-line area, remove the gravel, and then Simultaneously excavate the B-line area and A-line area by directional blasting or mechanical cutting along the line, and pour the gravel formed after excavation into the C-line trench and transport it away until the construction reaches the design grading size position. The construction method of the excavation of dangerous excavation in the mountain near the residential area obtained by the invention is simple and convenient, and will not affect the residential area.

Description

technical field [0001] The invention relates to a construction technology for danger removal in mountains, in particular to a construction technology for excavation in mountains near residential areas. Background technique [0002] When landslides occur on the mountains adjacent to buildings due to long-term weathering or multi-day precipitation, it is usually necessary to excavate or blast the mountains to prevent landslides or debris flows from causing harm to residential areas. However, when blasting is used, the flying rocks produced by the blasting will splash into the residential area, causing damage to the buildings and the bodies of the residents. At the same time, the noise and dust generated by the blasting are very large, so it is not suitable for the construction of the mountain near the residential area. construction. When using mechanical excavation, the mechanical equipment required for excavation is relatively large, and the construction site is required to ...

Problems solved by technology

However, when blasting is used, the flying rocks produced by the blasting will splash into the residential area, causing damage to the buildings and the bodies of the residents. At the same time, the noise and dust generated by the blasting are very large, so it is not suitable for the construction of the mountain near the residential area. construction

When using mechanical excavation, the mechanical equipment required for excavation is relatively large, and the construction site is required to be relatively stable, and the mountain structure is stable enough, but the mountain structure layer to be eliminated is not strong enough. There will be certain dangers for personnel and construction equipment, and this method is not suitable for relatively steep mountains
