Description
Technical field
The present invention relates to the equipment in the construction of mine shaft freezing engineering.More particularly, to one kind for longitudinal thermometric
Frigo.
Background technology
In current mine shaft freezing engineering construction, judge whether frost wall hands over circle often according to hydrological observation wells and temperature
Observation hole data is reacted, and part pit shaft is caused due to that cannot construct hydrological observation wells or hydrological observation wells set unreasonable
Hydrology hole report water level is inaccurate, thus the effect of thermometer hole more seems important.According to mine shaft freezing engineering job specfication
Regulation, " thermometric hole number when individual pen hole, double-round hole, three collar aperture are freezed per well should not be less than 3,4,5 respectively ".In reality
During the arrangement thermometer hole of border, it is typically chosen subsurface flow updrift side and adjacent pitch of holes maximum determines the position of thermometer hole, this
Require that geological hydrology data is accurate and freezing borehole and survey inclination of freezing hole are accurate.But during practice of construction, thermometer hole is not
The integral status of frost wall can completely be reflected, especially processed when frost wall does not hand over the pit shaft of circle for a long time, it is necessary to using longitudinal survey
Temperature technique carries out temperature measuring to judge frost wall integral status.
Often repeatedly supervised using single-point thermometric after freezing hole a period of time out of service during current freezing hole longitudinal direction thermometric
The means of survey are carried out, and its advantage is that single component reduces error itself, but the monitoring time is long, has both been unfavorable for the shape of frost wall
Into and repair, while monitoring personnel works and also influences efficiency at low ambient temperatures for a long time.Two improvement are carried out based on this, one is
Frigo head is transformed, two is that instead of single-point thermometric, (one-wire bus formula is referring to ZL using one-wire bus formula thermometric mode
2009 1 0093146.4 and ZL 2,008 1 is 0116209.9).
When in the prior art, using frigo longitudinal direction thermometric, after closing water inlet backwater valve, water inlet pipe top will be fixed on
The high-pressure rubber pipe in portion is unloaded, and temperature probe is put into PE plastic tubes by water inlet pipe carried out.Due to water inlet pipe port frosting with
And colligation, high-pressure rubber pipe is often not easy to remove, for rapid construction, usually by high-pressure rubber pipe it is sawed-off after changed, cause material
Material, the waste in artificial and man-hour.

(1) freeze：The three-way pipe that water inlet pipe is made up of a straight tube and an other pipe, second is provided with the straight tube
Gate valve, the 3rd gate valve is provided with the other pipe；4th gate valve is installed on return pipe；Second gate valve is normal during freezing
Close, the 3rd gate valve and the 4th gate valve are normally opened, by the other pipe to conveying salt solution, salt solution in the frigo head
After the frigo head and frost wall carry out heat exchange, from return pipe outflow.
(2) thermometric prepares：The 3rd gate valve closed on the other pipe, and the 4th gate valve closed on the return pipe.
(3) longitudinal thermometric：Second gate valve is opened, temperature probe is transferred into temperature measurement location along the straight tube, carried out
Thermometric.
Beneficial effects of the present invention are as follows：
Using frigo of the present invention when longitudinal thermometric is carried out, it is only necessary to close into backwater valve, water inlet pipe top is opened
Gate valve, it is easy to operate quick, do not result in the waste of salt solution and sebific duct, testing efficiency is high.
After using present invention construction, thermometer hole can be replaced using longitudinal thermometry, closure of freezing wall feelings are grasped comprehensively
Condition, it is ensured that freezing efficiency.Especially when treatment frost wall does not hand over circle accident pit shaft, this construction can accelerate monitoring process, as early as possible
Find out the weak link of frost wall.
Carrying out longitudinal thermometric using the present invention can save temperature observation hole pore-creating expense, such as current western part Soft Rock Area
Drilling expense is 450 yuan/m or so, and by taking 400m pit shafts as an example, the expense that using the present invention can save three thermometer holes is 540,000
Unit (is free of fee of material).
