Abstract
The utility model discloses a temperature measuring device for measuring freeze inside temperature of soil layer, its characterized in that device includes drill bit, temperature tube, hole piece, thermocouple, tin ingot and shielded wire. This device welds the thermocouple on the tin ingot, welds the tin ingot on the temperature tube pipe wall again, links together thermocouple and temperature tube through the tin ingot, has reduced the transmittance process of the cold volume of the soil body with the temperature tube pipe wall, just can with the cold volume transmission of the soil body for the thermocouple, record soil body temperature, reduced measuring error.
Description
Technical field
The utility model is specifically a kind of for measuring the temperature measuring equipment that freezes soil layer internal temperature.
Background technology
Along with the continuous growth of population and the relative decrease in space, the exploitation underground space has become the mankind and has expandedThe important means of living space and development trend. Subway construction is the important means that solves urban transport problems,In accordance with regulations, between two single track line tunnels, in the time that the coherent length in tunnel is greater than 600m, should establish service channel.
Freezing is reinforced due to its significant economic benefit and social benefit, on the higher stratum of city water contentWhen middle enforcement Metro Connected Passage-way Construction, there is extensive use. The thickness of Frozen Soil Cylinder and intensity should meet contactThe requirement of ground settlement and tunnel, especially ensures the thickness of horn mouth place freezing curtain, guarantees freezing curtain and right simultaneouslySide tunnel duct piece completely cementing. Carry out the cooperating that freezes and excavate, and according to freezing curtain after excavationDeformation is adjusted excavation construction technology in time. In order to grasp in time the state of development of freezing curtain, to refer toLead the construction of service channel, the inside of freezing curtain and around arrange perforate, for measuring solidification point.Adopt at present conventionally unsettled survey method to measure, use to pierce appropriate location in the soil body with the temperature tube of drill bit and stop,Then will stretch into fixed position in temperature tube with the shielding line of thermocouple, the cold of the soil body is by temperature tube pipeWall passes to the thermocouple of vacant state. Due to the effect of inner air tube thermal resistance, cause which in certain journeyOn degree, exist the cold between thermocouple and temperature tube tube wall to scatter and disappear, have very large error, often can not reflect the soil bodyTrue temperature. Therefore in the time that measured temperature reaches design temperature, soil temperature is often lower, while causing tunnelingExcavation part is extremely hard, strengthens difficulty of construction.
Utility model content
For the deficiencies in the prior art, the technical problem that the utility model quasi-solution is determined is to provide a kind of for surveyingAmount is freezed the temperature measuring equipment of soil layer internal temperature. This device on block tin, then welds thermocouple welding block tinBe connected in temperature tube tube wall, by block tin, thermocouple and temperature tube linked together, play set and do not damageThe effect of bad thermocouple. The integraty feature of this device has avoided the thermocouple causing in installation process to move.
The technical scheme that the utility model solve the technical problem is to provide a kind of and freeze soil layer for measuringThe temperature measuring equipment of internal temperature, is characterized in that device comprises drill bit, temperature tube, hole sheet, thermocouple, tinPiece and shielding line; Described drill bit is installed on one end of temperature tube; On described temperature tube, have at least one perforate;On the sheet of described hole, be welded with block tin, be welded with thermocouple on block tin, thermocouple is connected with one end of shielding line;The other end of described shielding line stretches out from the other end of temperature tube inside, external data treating apparatus; Described oneIndividual hole sheet is placed in a tapping and entirely welds, and the block tin on it and thermocouple are placed in to temperature tube inner side;The quantity of described perforate is all identical with the quantity of hole sheet, thermocouple and block tin.
Compared with prior art, the utility model beneficial effect is: this device by thermocouple welding in block tinUpper, then block tin is welded on temperature tube tube wall, by block tin, thermocouple and temperature tube are linked together,Play set and do not damage the effect of thermocouple. Hole sheet is welded on former position of opening, therefore avoids thermometer holeInterior water enters temperature tube, reduces the risk of water burst; In addition in thermocouple built-in pipe, can be to outside temperature tubeOther embodiment of side exerts an influence. Because the temperature of soldering is lower, compares a thermocouple and be directly welded in tube wallUpper, thermocouple damages and may greatly reduce. Such connected mode has reduced soil body cold and temperature tube simultaneouslyThe transmittance process of tube wall, just can pass to thermocouple by soil body cold, records soil temperature, has reduced measurementError. The utility model heat-exchanger rig is simple in structure, easy to operate, measures accurately.
Draw through great many of experiments: this measurement device gained temperature is than average accurate 1～2 DEG C of existing unsettled survey method,Be suitable for industrialization promotion, there is very high industrial value.

Detailed description of the invention
Technical scheme in the utility model embodiment is carried out to clear, complete description below, obviously,Described embodiment is a part of embodiment of the present utility model, instead of whole embodiment. Based on thisEmbodiment in utility model, those of ordinary skill in the art are institute under the prerequisite of not making creative workThe every other embodiment obtaining, belongs to the scope that the utility model is protected.
It is a kind of for measuring the temperature measuring equipment that freezes soil layer internal temperature (referring to figure that the utility model provides1-2, is called for short device), comprise drill bit 1, temperature tube 2, hole sheet 3, thermocouple 4, block tin 5 and shielding line 6;Described drill bit 1 is installed on one end of temperature tube 2; On described temperature tube 2, have at least one perforate, forInstalling hole sheet 3; On described hole sheet 3, be welded with block tin 5, on block tin 5, be welded with thermocouple 4, thermocouple 4Be connected with one end of shielding line 6; The other end of described shielding line 6 stretches out from the other end of temperature tube 2 inside,External data treating apparatus; A described hole sheet 3 is placed in a tapping and entirely welds, and by the tin on itPiece 5 and thermocouple 4 are placed in temperature tube 2 inner sides; The quantity of described perforate and hole sheet 3, thermocouple 4 and block tin5 is all identical; Described hole sheet 3 can do the polishing of prior art, makes hole sheet 3 have less contactThermal resistance, makes thermocouple 4 reflect more real soil temperature.
Described temperature tube 2 is low-carbon (LC) seamless steel pipe. Described hole sheet 3 is thermometrics that temperature tube perforate comes off afterwardsTube wall.
Operation principle of the present utility model and process are: first according to the quantity of point for measuring temperature, equal number is setThermocouple 4, now one end of shielding line 6 is positioned at temperature tube 2 inside, and is connected with thermocouple. Start working,Drill bit 1 pierces the appropriate location of freezing soil, and then drives temperature tube 2 to be positioned at the appropriate location of soil layer, incites somebody to actionThe other end of shielding line 6 is connected with external data treating apparatus, and soil temperature passes to block tin 5 by hole sheet, thenPass to thermocouple 4, carry out thermometric, external data treating apparatus by shielding line 6 image data, demonstration alsoProcess.
