Displacement control device and method in forced landing deviation correction technology
Technical Field
The invention belongs to the technical field of buildings, and particularly relates to a displacement control device and a control method thereof in forced landing deviation correction technology.
Background
The building structure deviation rectifying technology is a design construction technology for correcting the structural verticality of a building when the verticality deviation exceeds the standard allowance due to some reasons and the use is influenced and potential safety hazards exist due to the inclination of the building, so that the verticality meets the standard requirement.
The commonly used deviation rectifying methods are mainly divided into two types: one is the structural internal correction, namely, the vertical support (such as a column and a wall) of the structure is disconnected, and after the verticality correction is finished, the vertical support is continued, so that the verticality of the building meets the design and national standard requirements; the other is structural external deviation correction, also called forced landing deviation correction, namely, under the condition of not damaging the structure, one side with small settlement is forced to sink by methods of stacking, changing the foundation and the like so as to eliminate and offset the whole settlement difference of the structure and achieve the purpose of deviation correction.
As shown in fig. 1, in the forced landing deviation rectifying technology, because the characteristics of the foundation condition and the soil layer are difficult to grasp, the soil body is easily affected by water, and when the overall mass distribution of the structure is uneven, the situation of overusing often occurs, and the building that originally leans left is constructed and controlled improperly when the forced landing deviation rectifying is performed, and becomes a right inclination instead, resulting in the failure of deviation rectifying.
