Existing loess cave dwelling reinforcing method

Abstract

The invention discloses an existing loess cave dwelling reinforcing method comprising the following steps: 1, determining a cave dwelling arch ring reasonable arch axis: determining a reasonable arch axis of an arch ring in a to-be reinforced loess cave dwelling; 2, measurement and setting out: doing measurement and setting out outside a cave dwelling port of the to-be reinforced loess cave dwelling according to the determined reasonable arch axis equation y=f(x), thus measuring the reasonable arch axis of the arch ring; 3, cave dwelling arch ring soil cutting: using cutting equipment to cut the loess on the upper portion of the arch ring in the to-be reinforced loess cave dwelling according to the reasonable arch axis measured in the step 2, thus obtaining the cut cave dwelling. The method is simple in steps, reasonable in design, convenient to realize, good in usage effect, and can simply and fast effectively reinforce the loess cave dwelling.

Description

Technical field [0001] The invention relates to a method for reinforcing cave dwellings, in particular to a method for reinforcing existing loess cave dwellings. Background technique [0002] Cave dwellings are an ancient form of residence for residents on the Loess Plateau in northwest China. The history of this "cavern-style" dwelling can be traced back more than 4,000 years. Cave dwellings generally come in the form of cliff dwellings, sunken cave dwellings, freestanding dwellings, etc. Among them, patron kilns are mostly used, and patron kilns refer to loess cave dwellings dug by the mountains. At present, most of the cave dwellings used are arched cave dwellings. The arched cave dwellings include an arch ring and two left and right side walls respectively supported under the two arch feet of the arch ring. During actual use, the arch ring vault of loess cave dwellings is prone to local loess collapse. Therefore, it is necessary to regularly maintain the arch ring of the cav...

AI Technical Summary

Problems solved by technology

In the actual use process, the arch ring vault of the loess cave dwelling is prone to the problem of partial loess collapse. Therefore, regular maintenance of the cave arch ring is required. The maintenance workload and maintenance cost are high, and at the same time affect the service life of the cave dwelling. security risks

In addition, according to the force theory of the arch structure, when the curvature of the arch axis of the cave arch ring is small, the two arch feet of the arch ring will generate a large horizontal thrust, which will cause a certain degree of inclination of the side walls on both sides of the cave dwelling. , or even lose stability and collapse
