Problems solved by technology
[0004] At present, Hakka's earth building rammed earth wall repair technology has basically achieved the effect of rectifying the rammed earth wall and making up for the cracks, but it is insufficient to further prevent the cracking of the rammed earth wall that may occur in the subsequent use process, and there is no good solution to prevent subsequent use. Technical method for possible cracking of rammed earth walls during the process

Embodiment Construction
[0036] The purpose of the invention of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, and the embodiments cannot be repeated here one by one, but the implementation of the present invention is not therefore limited to the following embodiments.
[0037] Such as Figures 1 to 6 Shown, a kind of repairing method of Hakka earth building structure has the following steps:
[0038] S1. Cleaning: Install a scaffolding platform to facilitate construction workers to build an operation platform, remove the tiles on the roof 10, keep the tiles properly, select available tiles, and sort and stack them according to the texture after cleaning to save resources and restore the roof at the same time 10 The authenticity of the structure.
[0039] S2. Correction: correct the rammed earth wall 1 with an inclination rate exceeding 0.7%, and set up a correction structure outside the wall, specifically: insta...

The invention discloses a repairing method for a Hakka earth building structure. The repairing method comprises the following steps that reinforcement is conducted after cleaning and correcting are conducted, specifically, a tensioning device is arranged between two opposite rammed earth walls, and corner hoops are arranged at the joints of the adjacent rammed earth walls; the tensioning device comprises turnbuckles and two pull rod mechanisms, one ends of the two pull rod mechanisms are fixed on the two rammed earth walls correspondingly, and the other ends of the two pull rod mechanisms are connected through the turnbuckles; and each pull rod mechanism comprises a sleeve and a screw rod, the sleeve is installed on the rammed earth walls and penetrates through the rammed earth walls, one end of each screw rod penetrates through the corresponding sleeve, two T-shaped nuts are arranged at one end of each screw rod in a sleeving mode and located on the two sides of the rammed earth walls correspondingly, cushion blocks are arranged between the T-shaped nuts and the rammed earth walls, and the other ends of the screw rods in the two pull rod mechanisms are connected through the turnbuckles. The structural stability of the rammed earth walls is enhanced, the inclination angle of the rammed earth walls is corrected, and the rammed earth walls are effectively prevented from cracking and inclining again in the use process after being repaired.
Description
technical field [0001] The invention relates to the technical field of repairing traditional rammed earth buildings, in particular to a method for repairing Hakka earth building structures. Background technique [0002] The cracking and tilting of rammed earth walls is the most complicated problem in the repair of Hakka earth buildings. Due to the need for defense, the outer walls of Hakka earth buildings are mostly made of rammed earth. Large cracks that run through the longitudinal direction are prone to appear due to the influence of other factors, and then cause the multi-faceted rammed earth walls to tilt outward. [0003] To sum up, there are several reasons for the cracking and inclination of the rammed earth wall: 1. The material properties of the rammed earth wall itself; 2. The weakening of the four rammed earth walls causes the inclination of the rammed earth wall; 3. The roof of the earth building and the rammed earth wall Cracking caused by the weight of the ea...
