Description

Technical Field

[0001] The present invention relates to the technical field of ancient building ramming and patching, in particular to a rammed earth device simulating the ancient method of ramming and patching the city wall and its usage method. Background Art

[0002] Ancient buildings and city walls carry splendid civilizations, inherit historical cultures, and maintain national spirits. They are the "golden business cards" of the country. In recent years, the state has strongly supported the preventive protection of the cultural relics protection industry and proposed that when repairing ancient buildings, the original form, original structure, original materials, and original technology should be preserved. Through archaeological excavations, it is known that when the ancients rammed the city wall using the square slab building method, the outermost slab was in the shape of a square bucket with a larger top and a smaller bottom due to the ramming and extrusion expanding outwards. To maintain the stability of the city wall structure, the ancients created a unique trimming technique, that is, after the formwork was removed, the bundled wooden sticks were used to strike and shape from the outside forcefully. It can be seen that the ramming and patching of the city wall is not limited to the base plane, and may also be used for ramming and patching the inclined plane within a certain angle range. According to historical records and archaeological reports, the construction technology of ramming and patching the ancient city wall and the foundation of ancient buildings mostly completed by manpower, using ramming tools to ram up and down successively. The ramming tools were mostly stick rammers and bundled stick rammers. The ancient ramming tools did not use the rammer vertically up and down to tamp the soil, but struck obliquely to construct solid multi-layer ramming and patching layers that intersect longitudinally and transversely layer by layer. The diameter of the ramming tools varied with dynasties and regions and were all different.

[0003] In addition, the ancient city wall adopted the square slab building method, which rammed the city wall in sections and layers on the base in the groove of the proposed city wall section. During the excavation of the city wall, it was found that there were traces of ash and rotten wood in some column holes. It was inferred that the wooden bones might not be removed directly after the ramming slab was completed, but were directly retained in the city wall. Experts believe that its function is different from other wooden bones. This wooden bone is located at the intersection of the vertical and horizontal foundation trenches with a central column hole, and its function is equivalent to that of the "zhenmu". The archaeological site shows that the "zhenmu" will remain in the soil body, which can effectively reinforce the soil body and improve the strength parameters of the soil body.

[0004] When repairing the city wall body and the foundation of ancient buildings, the following problems are faced. The existing rammed earth device is designed according to contemporary construction requirements. The rammer uses the impact force of the up and down movement of the movable parts of the device to tamp the ground. According to the published patents, the shape of the rammer plate of this device is square, which can quickly tamp the ground flat. During the ramming process, the rammer plate continuously impacts the ground without interruption, and the dust is flying and the noise is relatively large at the ramming and patching site. Moreover, it is rather inconvenient for the platform carrying the ramming and patching tool to move. Such a construction environment will bring great inconvenience to the implementation of the project, and will also affect the physical and mental health of workers and cause environmental pollution.

[0005] In addition, the existing rammed earth device can only compact the ground with the impact force of the up and down movement of the movable parts, and cannot construct criss-cross stresses while tamping the earth. Therefore, when repairing ancient buildings, not only can the protection of cultural relics not be guaranteed according to the original shape, structure, and craftsmanship, but the structural strength of the rammed earth is also far inferior to the original structure. Summary of the invention
