SP (Self Propelled) plate assembling type ancient city wall reinforcing structure and construction method

Abstract

The invention provides an SP (Self Propelled) plate assembling type ancient city wall reinforcing structure and a construction method. The reinforcing structure is located on a wall body foundation at the bottom of a city wall soil body and comprises independent foundations which are symmetrically located at the two sides of the wall body foundation; the independent foundations are arranged along the length direction of the city wall soil body at an interval; the upper surfaces of the independent foundations are fixedly provided with structural steel frame rods; the structural steel frame rods are stuck on the outer surfaces of the two sides of the city wall soil body; the inclined angle of the structural steel frame rods is the same as that of the city wall soil body; the structural steel frame rods which are symmetrically located at the two sides of the city wall soil body are connected by a transverse pull rod which passes through a city wall; the adjacent structural steel frame rods at the same side are connected by a horizontal pull rod; an SP pre-stress hollow plate is inserted into grooves formed by flanges and web plates of the adjacent two structural steel frame rods; and outer walls are built at the outer sides of the structural steel frame rods and the SP pre-stress hollow plate. According to the SP plate assembling type ancient city wall reinforcing structure and the construction method, the technical problems that filled soil in an ancient city wall expands due to rainwater to collapse the outer built walls and no reliable reinforcing measures are available are solved.

Description

technical field [0001] The invention belongs to the field of reinforcement of ancient buildings, in particular to a reinforcement structure and a construction method for inserting SP boards into shaped steel as ancient city walls. Background technique [0002] Our country has a history and culture of 5,000 years, and a large number of city wall ruins have also been left behind. After years of erosion, the city wall will inevitably collapse and be damaged. Effective repairs after the collapse have become the focus of the ancient city wall reinforcement technology. In the prior art, what the city wall adopts is the reinforcement method that plain soil is filled inside and green bricks are wrapped outside. Once the city wall strengthened by this reinforcement method encounters continuous heavy rain, the soil inside the city wall will expand after being soaked in rainwater. As the lateral pressure increases, once the outer green brick wall cannot resist the huge lateral pressur...

Problems solved by technology

After the city walls of many famous tourist attractions have been repaired, the second collapse of the city wall is usually a "rain disaster". For example, the second collapse of the ancient city wall of Pingyao not only caused huge economic losses but also produced many negative social impacts
