When frost wall, the method to guarantee unstable full water and soil body stability in tunneling construction.During underground engineering construction,
The principle of stratum consolidation is the artificial cooling by hypothermic saline, and the water freezing in stratum forms frozen soil, completely cuts off underground water and ground
The connection of lower engineering, greatly improves the intensity of the soil body, it is possible thereby to can carry out applying for underground engineering under the protection of frost wall
Work.For example, establishing a refrigeration station in ground surface first during freezing slope construction, the freezing unit on ground surface is negative
The refrigeration work of circulating brine is blamed, hypothermic saline freezes cold source as main, and hypothermic saline (refrigerant agent) generally uses chlorination
Calcium aqueous solution, calcium chloride water is full of all containers and pipeline in the circulatory system, and the temperature of hypothermic saline is generally subzero
30 degrees centigrades are evenly arranged freezing hole between wellbore bottom and earth's surface, freezing pipe is lowered to work into freezing hole,
Hypothermic saline successfully freezes soil implementation using heat exchange by the construction location that freezing pipe is passed through on ground downstream to inclined shaft bottom,
Play the role of temperature pier.
In the inclined shaft freezing work progress of big height difference, due to hypothermic saline be from the ground surface with big height difference downstream to
Construction part, therefore will form biggish water pressure, in freezing process, the position freezed is also possible to will do it hypothermic saline
He constructs, and when personnel construct, may damage to freezing pipe, therefore freezing pipe can rupture, this biggish water
There is risk for pressure.Therefore, those skilled in the art provide a kind of big height difference brine recycling decompressor of inclined shaft freezing,
To solve the problems mentioned in the above background technology.
Summary of the invention
The purpose of the present invention is to provide one kind can effectively solve the problem that hypothermic saline is in cyclic process in big height difference inclined shaft

The lower freezing pipe upper end is connected with water tank, and the water tank upper end is connected with freezing pipe, the end of the upper freezing pipe with it is cold
The connection of jelly machine.
The features of the present invention also characterized in that
The water tank is a closed locking device, and water tank is placed on the safe location without construction.
The water tank is made of outer case and internal box, exocoel is constituted between the outer case and internal box, and exocoel is logical
Freezing pipe is crossed to be connected to refrigerator.
It is described outer intracavitary to be marked with external refrigerating system salt water.
The outer case upper center is provided with top connection, and the top connection is connect with upper freezing pipe.
It is provided with inner cavity in the internal box, it is described interior intracavitary to fill internal salt water.
Lower contact is provided in the middle part of the internal box lower end, the lower contact connects lower freezing pipe.
The exocoel inside and outside chilled brine temperature is lower than the inside salt water of inner cavity.
The beneficial effects of the present invention are:
The big height difference brine recycling decompressor of inclined shaft freezing of the present invention, by among the hypothermic saline circulatory system
Method of the water tank Jing Guo two heat exchanges is disposed, the hypothermic saline hydraulic pressure that can finally make construction freeze position reduces, Neng Gouyou
Effect solves the problems, such as that construction freezes position and freezes high pressure water bring engineering safety after tracheal rupture.

Specific embodiment
With reference to the accompanying drawing and specific embodiment the present invention is described in detail.
The present invention provides a kind of big height difference brine recycling decompressors of inclined shaft freezing, as shown in Figs. 1-2, including refrigerator
2, the refrigerator 2 is mounted on ground 1, there is inclined shaft 3 on the downside of the ground 1, and 3 bottom left of inclined shaft is construction part 7,
Lower freezing pipe 6 is installed, lower 6 upper end of freezing pipe is connected with water tank 5, and 5 upper end of water tank connects on the upside of the construction part 7
It is connected to freezing pipe 4, the end of the upper freezing pipe 4 is connected to refrigerator 2.
The water tank 5 is a closed locking device, and water tank 5 is placed on the safe location without construction.
The water tank 5 is made of outer case 51 and internal box 54, is constituted between the outer case 51 and internal box 54 outer
Chamber, and exocoel is connected to by upper freezing pipe 4 with refrigerator 3.
It is described outer intracavitary to be marked with external refrigerating system salt water 52.
51 upper center of outer case is provided with top connection 53, and the top connection 53 is connect with upper freezing pipe 4.
It is provided with inner cavity in the internal box 54, it is described interior intracavitary to fill internal salt water 55.
Lower contact 56 is provided in the middle part of 54 lower end of internal box, the lower contact 56 connects lower freezing pipe 6.
Chilled brine 52 temperature in the exocoel inside and outside is lower than the inside salt water 55 of inner cavity.
Working principle:
The water tank 5 disposed in the present invention is a closed locking device, and is placed on the safe location without construction,
It is exactly a heat-exchanger rig that water tank 5 is practical, is made of 54 two parts of outer case 51 and internal box, by the salt water of refrigerator 2
It obtains low temperature to flow in water tank 5 by above freezing 4 pipes, flows through external external refrigerating system salt water 52 and internal salt water 55 carries out heat
Exchange, the scene that internal salt water 55 flows into construction thus to obtain low temperature again freezes position, through circulation just constitute one it is new
If it happens the hypothermic saline circulatory system, position of freezing at the construction field (site) leak, it will be the salt water leakage shape an of low pressure
State ensure that safety.Moreover, because water tank 5 is to be placed on a home without construction in advance, although salt water follows
The hydraulic pressure that water tank 5 is flowed through during ring is higher, but water tank 5 is difficult to be destroyed due to construction.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
