Description

The observation procedure of a kind of tunnel subsidence and convergence
Technical field
The invention belongs to tunnel subsidence and Convergence monitoring method field, particularly relate to the observation procedure of a kind of tunnel subsidence and convergence.
Background technology
The sedimentation and the Convergence monitoring method that are applied to tunnel are at present a lot, that commonly used in the past has the sedimentation of precision level reversed rod observation tunnel vault, convergence instrument measures tunnel perimeter convergence, and this method precision is high, but needs for wider tunnel to work on chassis and be subject to construction interference large; The another kind of method be also in daily use is exactly that Trigonometric Leveling by Total Station measures Vault settlement, and total powerstation Opposite side survey method measures perimeter convergence, and this method needs reflector plate on vault and peripheral weld, and measuring accuracy is slightly low also can reach requirement.As long as a total powerstation can measure sedimentation and convergence simultaneously, relative settlement can be measured and can measure absolute settlement and convergence again with convergence, this is method the most frequently used at present, and shortcoming is that in construction, whitewashing can cover reflector plate and cannot observe, and needs to send someone to clear up with chassis.Other also has tunnel cross-section instrument also to can be used for sedimentation and Convergence monitoring, but ratio of precision total powerstation is lower slightly.Use the total powerstation of motor tracking target to mix special software to control the sedimentation of total powerstation automatic Observation and restrain to accomplish full-automatic observation, due to the interference of construction, total powerstation also can not be set up in tunnel motionless 24 hours every days, cannot accomplish Continuous Observation.
Summary of the invention
The object of the present invention is to provide the observation procedure of a kind of tunnel subsidence and convergence, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, present invention employs following technical scheme:
An observation procedure for tunnel subsidence and convergence, comprises the following steps:
1) several observation stations are chosen in the vault first in tunnel and vault both sides, then the observation station place punching chosen, and finally by hole and setscrew, hook are fixed on observation station place;
2) screw is utilized to be fixed on hook by some signal projectors that automatically can send microwave signal;
3) on the wall of bottom, choose two acceptance points in both sides, tunnel respectively, the receiver being used for Received signal strength is fixed on acceptance point place;
4) survey crew every day by USB flash disk, data Replica in receiver is taken back indoor importing software processing and can obtain sedimentation and convergence result.
Compared with prior art, beneficial effect of the present invention is as follows:
Within round-the-clock 24 hours, can work, without the need to human users in observation process, be hung on the impact that tunnel wall is not constructed; Signal projector and receiver are fixed on hook; Because in observation station and acceptance point, there is not the site error at each frame station when occurring that total powerstation is observed, improve accuracy of observation in equipment in the last direct screening of two lining constructions; Signal projector just simply sends signal, and receiver process is all electronic equipments with record data, and its price is also cheap, if lay multiple section, can purchase multiple signal projector and receiver.Replace GPS in Tunnel, complete static measurement, with kinetic measurement, there is the same advantage of GPS-RTK, signal projector compares satellite, signal projector is static and there is not orbit error and the ionospheric refraction equal error of satellite, and its signal is also strong than satellite several ten thousand times.
Accompanying drawing explanation
Fig. 1 is the arrangenent diagram of signal projector and receiver.
Embodiment
Below in conjunction with embodiment, optimal way of the present invention is described in further detail.
As shown in Figure 1, the observation procedure of a kind of tunnel subsidence and convergence, comprises the following steps:
1) several observation stations are chosen in the vault first in tunnel and vault both sides, then the observation station place punching chosen, and finally by hole and setscrew, hook are fixed on observation station place.
2) screw is utilized to be fixed on hook by some signal projectors 1 that automatically can send microwave signal.
3) on the wall of bottom, choose two acceptance points in both sides, tunnel respectively, the receiver 2 being used for Received signal strength is fixed on acceptance point place.
4) survey crew every day by USB flash disk, data Replica in receiver 2 is taken back indoor importing software processing and can obtain sedimentation and convergence result.
The technical solution used in the present invention is similar to GPS static observation, and the signal projector 1 that several send microwave signal is automatically fixed in the vault in tunnel and vault both sides, is called for short signal source, each signal source launches two kinds of wavelength microwaves, the receiver 2 of two Received signal strength is fixed on tunnel-side two side lower part, receiver 2 is divided into single channel and multiple passage, different frequency microwave signal single channel timesharing being received to a signal source utilizes beat-frequency meter to calculate the oblique distance of this signal source and receiver 2, and record, receiver 2 also carries transmiting signal source simultaneously, just Received signal strength and transmiting signal source have fixed skew, fixing phase differential is a constant, emissive source is below receiver 2, horizontalization receiver 2 when band circle leveling bubble is convenient to install on receiver 2, as long as receiver 2 flattens, emissive source is immediately below receiving phase, computer software process data separate fixed skew calculates the relative position of receiver 2.The interference of single channel receiver 2 in order to prevent multiple signal source from sending signal simultaneously, each signal source asynchronous transmission signal, if sampling interval 1 hour, each signal source transmission sigtnal interval is all set to 1 hour, each signal source transmission signal can be set stagger mutually 1 ~ 10 minute, receiver 2 utilizes the carrier phase difference of different frequency automatically to calculate the oblique distance of each signal source to receiver 2 when receiving signal, the transmission of setting signal source can be spaced apart 2 hours to more than 24 hours.The internal memory that the data of the short sampling of certain logging interval take more is also large.Signal source and each receiver 2 need to connect external power, and in order to prevent having a power failure, equipment carries rechargeable battery, and when having an electricity, charge in limit, limit.Survey crew every day can be copied by USB flash disk data in receiver 2 and be returned indoor importing software processing again and can obtain sedimentation and convergence achievement.Use multi-channel receiver 2 for high-power signal source, multi-channel receiver 2, each passage receives the signal in unlike signal source simultaneously, therefore undesired signal source asynchronous transmission signal.This equipment also can be used for control survey in tunnel and dynamically setting-out in real time, can replace GPS and cannot use problem in tunnel.Signal source can establish different frequencies, and multi-channel receiver 2 is that each signal source distributes different passages with software, and can be signal source and arrange different channel.
