Description

Horizontal displacement monitoring device
Technical field
The utility model relates to engineering survey apparatus field, in particular to a kind of horizontal displacement monitoring device
Background technology
Monitoring point for displacement is the survey mark that reflection monitoring target space displacement changes, and for guaranteeing accuracy and the monitoring accuracy of monitoring, long durability need to firmly be installed and have to monitoring point for displacement.While adopting traditional transit intersection to measure, conventionally adopt the roundlet ball of irony or macromolecular material making as horizontal displacement monitoring dot mark; While adopting total station instrument coordinate method to measure, conventionally adopt reflector plate (or prism) as horizontal displacement monitoring dot mark.
There are the following problems for said method: the bead of 1. making of irony or macromolecular material coordinates intersection to measure as horizontal displacement monitoring dot mark, can realize high-acruracy survey, but to around place and sighting condition have relatively high expectations, monitoring amount is large, and cannot realize automatic monitoring; 2. adopt reflector plate can realize coordinate method as horizontal displacement monitoring dot mark and measure, greatly save workload, but permanance is poor, cannot guarantee chronicity and periodically monitoring.
Therefore, need a kind of new horizontal displacement monitoring device, both can be used for traditional intersection and measured, can be used for again total station instrument coordinate method and automatically measure, can guarantee to monitor monumented point high stability, can guarantee long-term useful life longevity again.
Utility model content
Technical problem to be solved in the utility model is, a kind of new horizontal displacement monitoring device is provided, had both can be used for traditional intersection and measured, can be used for again total station instrument coordinate method and automatically measure, monumented point high stability can be guaranteed to monitor, long-term useful life longevity can be guaranteed again.
In view of this, the utility model provides a kind of horizontal displacement monitoring device, comprise spherical markers point, prism, prism protective sleeve, waling stripe and vertically connecting rod, wherein: described spherical markers point is installed in one end of described waling stripe, the other end is provided with for connecting the screw thread of monitoring target, and middle part has through hole, described vertical connecting rod one end is inserted in described through hole also locked by bolt, the other end is installed described prism protective sleeve, described prism is arranged in described prism protective sleeve and along being circumferentially evenly provided with four grooves, forms groove type target cross on described prism protective sleeve, be used for helping instrument to aim at.
Wherein, prism protective sleeve is processed by stainless steel, and threaded hole is opened in rear end; by threaded hole, little prism is screwed in prism protective sleeve; prism protective sleeve shape is similar to bucket, its opening, and groove type target cross is processed in position, prism protective sleeve upper and lower, left and right.
During concrete use, horizontal displacement monitoring device for marking is arranged in monitoring target.During installation, by spherical markers point and waling stripe according to having a down dip in the relative height of monitoring point and ground survey instrument, until the axis of waling stripe instrument collimation axis when aiming at overlaps, fixing spherical markers point; Then prism protective sleeve is connected it by vertical connecting rod with waling stripe, left rotation and right rotation prism protective sleeve until when aiming at instrument collimation axis upright position, binding bolt; Prism is screwed in prism protective sleeve, complete installation.While measuring operation, on fixed deformation monitoring pier, settle transit or total powerstation, aiming at the spherical markers point (angle intersection method measurement) of integrated form horizontal displacement monitoring sign or the groove type target cross of four groove formation (coordinate method is measured or measurement automatically) measures, and calculate monitoring point coordinate position, by comparison not coordinate figure in the same time calculate the distortion of each position of monitoring target in monitoring periods.
The stability of monitoring monumented point is the key that guarantees deformation monitoring quality, the technical program is taken into account the General Requirement of tradition and modern surveying method, select as required monitoring scheme, taken into full account the hight coordinate with surrounding environment, structural relation can regulate according to field condition, has guaranteed macrobiosis future and the high stability of long term monitoring, and practicality, versatility are all good, especially needing the upper arrangement of the monitoring target of long term monitoring (as landmark), there is more significant meaning.
