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

Embodiment Construction

[0037] Such as figure 1 A reinforcement method for an existing loess cave dwelling is shown, including the following steps:

[0038] Step 1. Determination of the reasonable arch axis of the cave arch circle: combined with the structural parameters of the loess cave to be reinforced, and according to the formula Determining the reasonable arch axis of the arch ring in the loess cave dwelling to be reinforced; the loess cave dwelling to be reinforced is an arched cave dwelling that has been put into use;

[0039] The structural parameters of the loess cave dwelling to be reinforced include the height f and the span l of the arch circle in the loess cave dwelling to be reinforced;

[0040] In the formula (1), the function y=f(x) is a reasonable arch axis equation; γ is the average bulk density of the loess covered by the arch circle in the loess cave to be reinforced; Wherein h is the height of the left and right side walls 2-1 in the loess cave dwelling to be reinforced;

Abstract

The invention discloses a reinforcement method for an existing loess cave dwelling, comprising steps: 1. Determining the reasonable arch axis of the arch circle of the cave dwelling: determining the reasonable arch axis of the arch circle in the loess cave dwelling to be reinforced; 2. Measuring and setting out the line: according to the determined The reasonable arch axis equation y=f(x) of the loess cave dwelling to be reinforced is carried out on the outside of the cave entrance of the loess cave dwelling to measure and set out to measure the reasonable arch axis of the arch ring; three, the cutting of the cave arch ring soil: according to step 2 Based on the measured reasonable arch axis, cutting equipment is used to cut the upper part of the arch ring in the loess cave dwelling to be reinforced to obtain the cut cave dwelling. The method of the invention has the advantages of simple steps, reasonable design, convenient realization and good application effect, and can effectively reinforce loess cave dwellings simply and quickly.

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 living form of residents on the Loess Plateau in Northwest China. The history of this "cave-dwelling" dwelling can be traced back to more than 4,000 years ago. Cave dwellings generally have cliff-like cave dwellings, sunken cave dwellings, and free-standing cave dwellings. Among them, mountain kilns are more widely used, and mountain kilns refer to loess cave dwellings dug against mountains. At present, most of the cave dwellings used are arched cave dwellings, and 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. 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 mainte...
