A method for non-destructive identification of floor diseases and rapid micro-damage repair of floor diseases

Abstract

The invention discloses a method for nondestructively recognizing floor diseases and rapidly and micro-destructively repairing the floor diseases. The method comprises the following steps: detecting adisease area of a floor by using a ground penetrating radar, and detecting the bearing capacity of a foundation of the disease area by using a conical dynamic sounding device; forming a grouting holein the disease area of the floor on the basis of the bearing capacity of the foundation of the disease area, and carrying out grouting on the disease area by using polyurethane through the grouting hole; detecting the disease area by the ground penetrating radar and the conical dynamic sounding device after the disease area is subjected to grouting, and plugging the grouting hole after a detecting result meets requirements. The method has the advantages that the foundation of a disease position of the floor is reinforced effectively, secondary hollowness is avoided, and by huge expansion acting force generated by reaction, effective lifting repair on deformation or sedimentation caused by hollowness of the floor can be implemented.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a method for nondestructively identifying floor disease and quickly repairing floor disease with minimal damage. Background technique [0002] As the direct carrier for people and transport machinery to walk, the floor is an important part of buildings. Its common disease phenomena include hollowing, settlement and so on. For warehouses, workshops and other structural buildings, due to the long-term parking of heavy vehicles, equipment or materials, during the transportation and installation of mechanical equipment and the rolling and vibration of vehicles, the subsidence of the foundation soil due to its own compression and shrinkage of the floor concrete will produce Small-area hollowing or floor deformation will continue to expand under vibration, resulting in large-area hollowing and foundation compression deformation, resulting in subsidence deformation and ...

AI Technical Summary

Problems solved by technology

[0008] 1. Since the grouting resin itself only has micro-expansion, it is impossible to lift and repair the floor settlement caused by hollowing, and hollowing often causes certain settlement and deformation of the floor

[0009] 2. After the hollowing is repaired by grouting, it still takes 48 hours for the grouting resin to harden. During this period, trample vibration is not allowed, which still has an impact on the use of the floor

[0010] 3. It can only be filled, and the weak foundation around the hollow can not be reinforced, and the problem of hollow can not be solved fundamentally, and it is easy to produce secondary hollow

[0011] Obviously, the traditional detection and repair technology has certain defects in the treatment of floor diseases, and a fast, simple and effective method for detection and treatment of floor diseases is needed
