Portable wall space deformation monitoring device for reinforced soil retaining wall and monitoring method

Abstract

The invention discloses a portable wall space deformation monitoring device for a reinforced soil retaining wall and a monitoring method. The portable wall space deformation monitoring device for the reinforced soil retaining wall comprises a flexible rail arranged on the fracture surface of a to-be-monitored reinforced soil retaining wall and a testing device arranged on the flexible rail and capable of moving along the flexible rail. The laser ranging technology is applied to the wall space deformation detecting field for a retaining wall, and the application of the laser ranging technology in the wall face deformation detecting practice is achieved, so that the prototype detecting work for the reinforced soil retaining wall is more convenient. Compared with the current monitoring and detecting, the wall space deformation detecting result for the reinforced soil retaining wall is more practical, more objective and more scientific. In addition, multi-purpose (beside from the reinforce soil retaining wall, measuring can be carried out on various flexible walls) in one device is achieved. The device is simple and capable of meeting the requirement of environmental protection, energy conservation and economical efficiency in the present society, so that the application prospect is extremely wide.

Description

technical background [0001] The invention belongs to the fields of civil engineering and electromagnetism, and relates to a measuring device for wall surface deformation of a retaining wall, in particular to a portable reinforced soil retaining wall wall deformation monitoring device and a monitoring method. Background technique [0002] With the continuous development of highway construction in recent years, there are more and more highway ancillary facilities such as high slope engineering projects. In the construction process, it must meet higher requirements in terms of stability and durability. Therefore, how to ensure that the high slope support structure has sufficient safety during its service life, avoid the occurrence of geological disasters, and reduce the personal and property safety of expressway users has become the designer's responsibility for the high slope support structure. Important factors that must be considered when designing. [0003] Deformation...

Problems solved by technology

The main disadvantage of the station observation method is that it is subject to the limitation of terrain visibility conditions and the influence of meteorological conditions, the workload is large, the cycle is long, and the continuous observation ability is poor.

The instrument observation method has high observation accuracy, but its economy is poor. Only the units specialized in observation work have this observation equipment, and it is not commonly used by ordinary personnel for deformation observation.

At the same time, it cannot rule out the impact on the structure and mechanical performance of the retaining wall due to the vertical measuring pipe buried in the retaining wall
