Embodiment 1

[0026] An in-situ restoration method for loess cave dwellings, specifically as figure 1 shown, including the following steps:

[0027] S1, laying out the waterproof and drainage system outside the overburden of the cave dwelling;

[0028] S2, laying slope protection system on the exterior of cave dwelling overburden with waterproof and drainage system;

[0029] S3, in-situ grouting on the inner wall of the cave dwelling, and use soil nails to reinforce the grouting part after the grouting is completed;

[0030] S4, use loess fiber coating on the inner wall of the cave dwelling reinforced by soil nails;

[0031] S5, laying the permeable pavement system 7 on the road in front of the cave dwelling.

[0032] In the present invention, a waterproof and drainage system is set to intercept and divert the water flow on the overlying soil of the cave dwelling. The water pipe 4 is composed, and the flexible water pipe 1 and the ecological drainage channel 2 are all laid according to ...

Abstract

The invention discloses an in-situ repair method for a loess cave dwelling. The in-situ repair method comprises the following steps that a water prevention and drainage system is arranged outside a cave dwelling covering soil body; a slope protection system is laid outside the cave dwelling covering soil body provided with the water prevention and drainage system; in-situ grouting is conducted onthe inner wall of the cave dwelling, and after grouting, the grouting part is reinforced through soil nails; the inner wall of the cave dwelling reinforced through the soil nails is plastered througha loess fiber coating; and a water permeable pavement system is laid on the road surface in front of the cave dwelling. Aiming at engineering diseases prone to occurring in the cave dwelling in a loess area and combining the new concepts of ecology, low carbon and the like, systematic and comprehensive in-situ repair of the loess cave dwelling is achieved from external water control and drainage,and plastering to internal grouting and reinforcing; according to the in-situ repair method, all the engineering diseases of the loess cave dwelling can be eliminated, the original internal and external environment of the cave dwelling can further be kept, and in-situ repair is really achieved; and meanwhile, the in-situ repair method is ecological, low in carbon, environmentally friendly and safe, and is suitable for being widely applied in cave dwelling repair in the loess area.

Description

technical field [0001] The invention belongs to the technical field of building restoration, and in particular relates to an in-situ restoration method for loess cave dwellings. Background technique [0002] As a representative of the former revolutionary site, Yan'an Loess Cave Dwelling is a product of the Loess Plateau. It carries the unique revolutionary connotation and the Yan'an spirit of hard work, and is a shining business card of Yan'an. However, these loess cave dwellings have potential safety hazards under the long-term erosion of rainwater, and are threatened by geological disasters such as landslides and mudslides around them. If no measures are taken to protect and repair them, they will become increasingly dilapidated, and the revolutionary spirit and culture they carry will also be destroyed. wither. Therefore, in response to this series of diseases, it is necessary to design a restoration method for loess cave dwellings, so that it can reduce or eliminate ca...
