Building rectification device and method

Abstract

The invention discloses a building rectification device and method. Through the building rectification device and method, the deficiencies that in the existing building jacking rectification construction process, the jacking rectification effect is poor, construction is tedious, a building is even likely to be damaged, and an original structure of the building is damaged are overcome. The building rectification device comprises a high-pressure grouting machine placed outside building foundations, an expansion pipe and a grouting pipe. The expansion pipe and the grouting pipe are installed below a building ground beam. The expansion pipe is arranged above the grouting pipe. The outer ends of the expansion pipe and the grouting pipe are both connected with the high-pressure grouting machine through pipelines. The inner wall and the outer wall of the expansion pipe are both of a corrugated-pipe-shaped structure. The two ends of the expansion pipe are both fixedly connected with the building foundations. An exhaust pipe is connected with the inner end of the expansion pipe and extends out of the building foundations. The extension end of the exhaust pipe is connected with a closing cover. A plurality of slurry discharge pipes are arranged on the outer wall of the grouting pipe in the length direction. In the building jacking rectification construction process, the jacking rectification effect is good, construction is simple and convenient, a building is not damaged, and an original structure of the building is kept.

Description

technical field [0001] The invention relates to a building deflection correction technology, more specifically, it relates to a building deflection correction device and method using an expansion tube. Background technique [0002] After many buildings have been used for a long time, the two sides of the foundation will have different degrees of settlement, which will lead to the inclination of the building. The national regulations have clear regulations on the inclination of buildings at all levels. Buildings that exceed the regulations must try to correct the deviation. or dismantle. At present, the methods of correcting deviations of buildings can be roughly divided into two categories, namely forced landing and deviation correction methods and jacking deviation correction methods. Among the two methods, jacking deviation correction methods are more costly and difficult, but there are requirements for the elevation of the building's indoor floor. If so, it is recommende...
