Abstract
The utility model discloses a kind of devices for monitoring tunnel surrounding internal temperature, its composition is: more than two temperature sensor probe (2a) genesis analysis are simultaneously embedded on the probe hole of PPR pipe (1), the signal output end of temperature sensor probe (2a) is located at the inner cavity of PPR pipe (1), the inner end of signal wire (2b) is connected with the signal output end of temperature sensor probe (2a), is connected after the nozzle of outer end stretching PPR pipe (1) of signal wire (2b) with the signal input part of temperature sensor (2).The tunnel surrounding internal temperature gone out using the device monitoring is more acurrate, reliable, and its operation is easy, testing cost is low.
Description
Technical field
The utility model relates to a kind of devices for monitoring tunnel surrounding internal temperature.
Background technique
Under geothermal environment, tunnel surrounding complex geologic conditions, temperature has certain changes in distribution in country rock.How
The relationship of temperature and temperature and country rock depth inside accurate measurements tunnel surrounding, holding the country rock temperature regularity of distribution is tunnel
The important leverage that construction safety is gone on smoothly is the correct basic premise chosen construction method, formulate heat insulation and heat control measure, and
The important evidence of rational allocation personnel's machinery.
In order to detect the temperature and gradient inside different depth country rock, the way of the prior art is: by setting on reinforcing bar
Interval binds multiple temperature sensing probes, then reinforcing bar and its probe are inserted into country rock body, ordinary mortar sealing of hole is used afterwards, to sand
After starching solidification-stable, signal will test by the signal wire connecting with temperature sensing probe and be sent to temperature sensor, by temperature
Sensor reads the temperature at different measuring points probe, realizes the monitoring of country rock internal temperature and gradient.Itself the problem is that: 1,
The temperature sensing probe of binding is easy to happen displacement during being inserted into country rock body and mortar sealing of hole, causes measuring point fixed
Position is inaccurate, thereby reduces the accuracy of temperature and gradient monitoring.2, the heat conductivity of reinforcing bar is high, the heat transfer between measuring point compared with
Fastly, the temperature interference between adjacent measuring point influences big, cannot accurately measure the temperature value of different depth, the accuracy of measurement data
It is to be improved with reliability.3, before mortar sealing of hole, signal wire is exposed at the surface of reinforcing bar, in operation, is easy scratch even
Damage, needs to repair or remake, improves testing cost.
Summary of the invention
The purpose of this utility model is to propose a kind of device for monitoring tunnel surrounding internal temperature, is gone out using the device monitoring
Tunnel surrounding internal temperature it is more acurrate, reliable, and its operation be easy, testing cost it is low.
The utility model realizes its goal of the invention the technical scheme adopted is that a kind of monitoring tunnel surrounding internal temperature
Device, composition is:
More than two temperature sensor probe genesis analysis are simultaneously embedded on the probe hole of PPR pipe, and temperature sensor is visited
The signal output end of head is located at the inner cavity of PPR pipe, and the inner end of signal wire is connected with the signal output end of temperature sensor probe, believes
The outer end of number line is connected after stretching out the nozzle of PPR pipe with the signal input part of temperature sensor.
The application method of the utility model is:
The area Xian Duice tunnel surrounding is drilled to obtain the monitoring holes that aperture is greater than PPR pipe caliber, then by the utility model
Part of the device in addition to temperature sensor, be inserted into monitoring holes, temperature sensor is placed in outside monitoring holes.Again by comprehensive silicon
Hydrochlorate thermal insulation mortar is pressed into the inner cavity of PPR pipe and the gap of PPR pipe wall and monitoring holes, makes the inner cavity of entire monitoring holes and PPR pipe
Full of mortar.After mortar complete stability, it is corresponding that the tunnel surrounding that each temperature sensor probe is measured is acquired by temperature sensor
The temperature of depth realizes the monitoring to tunnel surrounding internal temperature.
Compared with prior art, the utility model has the beneficial effects that
One, probe is fixed on the probe hole of PPR pipe, and the distance between probe is accurate, fixed, and the positioning of each measuring point is quasi-
Really, the accuracy of temperature and gradient monitoring is improved.
Two, the thermal insulation medium that the casing wall between each measuring point, composite silicate heat preservation mortar are formed is heat-resisting, heat-insulated material
Material, heat conductivity is low, and the heat transfer between measuring point is slow, and the temperature interference influence between adjacent measuring point is small, so as to accurately measure
The accuracy and reliability of the temperature value of different depth, measurement significantly improves.
Three, in the operating process that apparatus main body is inserted into monitoring holes, signal wire is located at PPR pipe inner cavity and is protected,
It will not be scratched or damage, reduce operation difficulty and testing cost.
Further, the temperature sensor probe of the utility model is Pt100 thermal resistance, and the temperature sensor is
Pt100 thermal resistance temperature sensor.
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Detailed description of the invention
Fig. 1 is schematic cross-sectional view when being not used for the utility model.
Fig. 2 is for schematic cross-sectional view when the utility model is used.Label 3 is country rock in Fig. 2, and label 4 is mortar.
Specific embodiment
Embodiment
Fig. 1 is shown, and a kind of specific embodiment of the utility model is a kind of dress for monitoring tunnel surrounding internal temperature
It sets, composition is:
More than two temperature sensor probe 2a genesis analysis are simultaneously embedded on the probe hole of PPR pipe 1, temperature sensing
The signal output end of device probe 2a is located at the inner cavity of PPR pipe 1, and the inner end of signal wire 2b and the signal of temperature sensor probe 2a are defeated
Outlet is connected, and is connected after the nozzle of the outer end stretching PPR pipe 1 of signal wire 2b with the signal input part of temperature sensor 2.
The temperature sensor probe 2a of this example is Pt100 thermal resistance, and the temperature sensor 2 is Pt100 thermal resistance temperature
Spend sensor.
