Description

Reinforced structure is used in ancient building rammed earth wall construction
Technical Field
The invention relates to the technical field of historic building earth wall construction reinforcement, in particular to a reinforcing structure for historic building rammed earth wall construction.
Background
Archaeological findings show that China builds walls by a soil ramming method four thousand years ago, rammed soil houses have been built in the times of invar, the native buildings are generated in the times of neolithic apparatus four thousand years ago in China, mature soil ramming technology exists in the times of invar 16 century before the time of the first 16 th century to 11 th century before the time of the first yen, more rammed soil walls are used in the buildings of the folk dynasty to the Han dynasty, wood bone wall ribs in the horizontal direction are used in the rammed soil walls and are called as ' wood', the method is used up to the Hanchanan city and down to the south and north dynasty, the Tang and the Song dynasty, the dynasty and the palace walls of the Chang dynasty are rammed soil walls, and the lining houses in the Song dynasty are separated by the rammed soil walls, and the northern Song dynasty soil ramming technology is improved. The achievement of the rammed soil version construction technology at that time is systematically summarized in the book of construction legal system of less supervision of plum compilation by northern songham. Wherein, the 'wall building' is specified, every wall is three feet thick, nine feet are high, the upper part is obliquely contracted, and the specific thickness is reduced by half; if the height is increased by three, the thickness is increased by one, and the thickness is decreased by the same. The Fujian earth building pushes the traditional rammed earth construction technique of China to the crest, the plate rammed earth wall is the earliest method for constructing city wall in China, it is made up by using wood plate as mould, filling clay or limestone in it, ramming and building them layer by layer with pestle, along the great wall, there are many rammed earth walls which are made up by using clay and sand and then by using branches of Salix purpurea or reed, and there are also some places which are made up by using soil, sand and lime and ramming stone, the plate rammed earth wall has a height which is about one time of bottom thickness, and the top width is about one fourth to one fifth of the wall height, so that the city wall has obvious collection and utilization, and it has a certain bearing capacity, and can prevent soldier's actions, resist the attack of cold weapons (knives, robbery, arrows, etc.), and can use materials, and the construction is simple and convenient, so the plate rammed earth wall is faced to the left and right of the old Chinese generation, and 15 th layers, due to the progress of the city building technology, the ramming layer for the Tang generation and the Ming generation is about 30 centimeters, but the wall is easy to be damaged by enemies, for example, wood ribs are obviously arranged on the beacon platforms of the Yumenguan and the Han great wall, the wood ribs are regularly spaced by a plurality of meters and are stored up to now, some Tang dynasties such as the great ancient castle of the Yangsheng city and the Ming dynasty are rotten, and a little corrosion-resistant wood is remained, reed ribs are regularly distributed in the big and small square disk cities of the Yumenguan, the upper part, the lower part, the left part and the right part are respectively spaced by about 20 centimeters, the thickness of the Han great wall is enough to allow 2 full-side armored soldiers to oppositely pass through, the existing thickness is more than 1.2 meters, the height of the city wall is about 8-18 meters, the overall firmness and skill of the city building are reflected, a part of the great wall is built by adopting a method of ramming a plate, the soil wall is made of soil, and the quality of the soil wall is directly related to the firmness of the soil wall. The area where the Fujian earth building is located is mountainous and has much earth, and the building can be made of local materials. Loess with better viscosity and more sand is generally selected, and if the viscosity is not enough, field cape mud (also called field bottom mud), namely clay which has not been cultivated on the lower layer of the paddy field, is also added. The shrinkage of the clean loess after drying is large, the compacted soil wall is easy to crack, the water shrinkage rate can be reduced by sand content so as to reduce the cracking of the soil wall, and the cracking of the soil wall can also be reduced by some soil (old wall mud) blended with the old wall. The clay is mixed to increase viscosity and ensure the integrity and sufficient strength of the wall body, and because the sand content of the soil in each place is different, the mixing proportion of the loess, the clay and the old wall mud is completely determined by experience, the raw soil can not be directly used generally, the raw soil and the mixed field bottom mud need to be repeatedly turned over and hoed, broken and uniformly mixed, the hoeing is more careful, the stacking time is longer and better, the humus in the soil is actually promoted to be lost through fermentation (commonly called 'curing'), the soil wall formed by the soil is high in strength and not easy to crack, and the 'Sanhe soil', namely the loess, the lime and the sand are mixed and tamped in some ancient buildings, and brown sugar and husked rice pulp are also mixed in some soil to increase the hardness degree of the soil wall. The iron nails of the earth wall formed by ramming earth are difficult to nail, and are still intact after hundreds of years of weather. In addition, the control of the water content in the soil during tamping is also the key to ensure the quality of the earth wall. The water content is too little, the viscosity of the soil is poor, and the rammed soil wall is loose in texture and obviously not firm; the water content is too much, the native wall can't be tamped, the easy shrink fracture of wall body behind the moisture evaporation, it leads to the wall body fracture to accumulate wind-force effect and rainwater scouring in the course of passing through day and month, need maintain ancient building, and rammed earth building can not directly be under construction to it when being under construction, exogenic action can lead to the crack grow of ancient building wall body or collapse, so need have a reinforced structure to consolidate it when ancient building wall body restores, maintain the firm of wall body, play the safeguard effect to staff's safety simultaneously.
