TECHNICAL FIELD
[0001] The utility model belongs to the field of support, specifically relates to a GNSS receiver outer wall right angle support for highway deformation monitoring. BACKGROUND
[0002] Highway, especially long and large highway, will inevitably encounter special sections such as high slope, soft soil subgrade, joint construction of highway and railway, joint construction of river and road subgrade, etc. due to long span and complex and changeable topography and geological conditions along the line. The potential deformation risk of these sections is often large, and serious ones can cause the road surface to appear wavy undulation, longitudinal cracking of the road surface, and even subgrade landslide, collapse and other problems, which seriously affect the driving safety and the safety of people's lives and property. Therefore, during the construction and operation of the highway, it is necessary to monitor the subgrade of the section with high risk.
[0003] Subgrade monitoring often carries out multiple monitoring projects at the same time, among which two very important ones are subgrade vertical displacement and subgrade horizontal displacement monitoring, which are often used to judge the safety state of the subgrade. The subgrade monitoring section spacing is often set to be 100m-200m; each monitoring section is often set to have 2-4 monitoring points; the monitoring frequency is one week to one year; and the operation period is often full-closed operation. That is to say, the subgrade monitoring of the highway often has the characteristics of long monitoring section, long monitoring section spacing, few monitoring points in the section, long monitoring interval, difficulty in joint monitoring reference point, and high risk of crossing the highway.
[0004] At present, the subgrade vertical displacement is generally measured by leveling, and the subgrade horizontal displacement monitoring is mainly carried out by combining GNSS static observation and total station traverse. The above monitoring methods are theoretically complete and reliable in accuracy, but have high field intensity and low operation efficiency, and have high risk when operating on the highway.
[0005] In recent years, the method of high-frequency and high-precision subgrade three-dimensional deformation monitoring represented by Beidou navigation positioning technology has been increasingly favored and used by people. This method installs a GNSS monitoring receiver at the deformation monitoring point and a GNSS reference station at a stable position outside the deformation area, and through the joint solution of the GNSS monitoring receiver and the GNSS reference station, high-frequency and high-precision three-dimensional deformation data can be obtained. This method can realize long-term intelligent monitoring at one time, and overcome various disadvantages and shortcomings of manual monitoring. In order to ensure the accuracy and reliability of the GNSS monitoring data and the safety and stability of the GNSS receiver, how to install the GNSS receiver is very important. At present, the GNSS of the subgrade slope is generally installed by excavating a pit on the ground, pouring a concrete block, and then fixing the GNSS receiver on the concrete block through a rod. However, there is no relevant report on how to install the GNSS receiver for the retaining wall structure of the highway slope.
[0006] GNSS is the abbreviation of Global Navigation Satellite System, which is a space-based radio navigation positioning system capable of providing all-weather three-dimensional coordinates, speed and time information.
[0007] The utility model discloses in reliance on the deformation monitoring engineering expressway side slope structure is the retaining wall structure form, and the left and right amplitude roadbed exists 2m or so height difference, and the emergency lane does not have the installation condition, if the GNSS receiver is installed in retaining wall side slope one side ground, then the GNSS receiver signal will be shaded, and the signal quality is difficult to guarantee, if the GNSS receiver is installed in retaining wall top, then the GNSS receiver is easy to be influenced even damage by the passing vehicle. Therefore, need in view of the engineering specific working condition, develop a kind of for the GNSS outer wall right-angle support of expressway deformation monitoring, make GNSS receiver avoid driving lane or emergency lane, to ensure GNSS receiver signal quality and the safety and stability of GNSS receiver itself.
