Description
Technical field
The present invention relates to tunnel surrounding field, especially a kind of buried earth temperature energy hot exchange system of energy tunnel layer.
Background technique
The soil moisture in hundreds of meters of layer of earth superficial is with depth in increasing trend, depth 100 meter temperature rises of every increase
About 3-5 DEG C high, the ground temperature at 1000 meters of underground is about 40-50 DEG C, is stored in hundreds of meters of buried depth of mountain tunnel country rock huge
Ground temperature energy.There are two types of existing tunnel surrounding ground temperature energy extractive techniques, one is directly collect tunnel surrounding in GEOTHERMAL WATER,
The technology belongs to passive extractive technique, but the technology is only applicable to the area of rich groundwater, small or without underground in groundwater run off
The area of water can not then apply；Another is to bury heat-exchange tube between tunnel double-lining and just lining, passes through the heat transfer in pipe
The temperature difference between circulatory mediator and country rock extracts tunnel surrounding ground temperature energy, which belongs to active extractive technique, not climate item
Part limitation, but the technology needs additional laying heat exchange pipe, increases construction cost and construction period, heat-exchange tube tube wall heat conduction
Property is bad, causes the heat exchange efficiency of heat-exchange tube low.
Summary of the invention
It can not be applied to mentioning for full section of tunnel country rock ground temperature energy to overcome existing tunnel country rock GEOTHERMAL WATER to collect technology
It takes, and is laid with heat exchange pipe and will increase engineering-built cost and delay the problems such as construction period, the present invention provides a kind of be applicable in
Property it is good, heat exchange efficiency is higher, save cost and saves the buried earth temperature energy hot exchange system of energy tunnel layer of construction period.

Just the injection waterproof layer between lining and heat exchange layers and the Water -proof Membrane between the heat exchange layers and tunnel double-lining.When
So, other waterproof types can also be used.
Further, setting sealing separates in the heat exchange layers, and the sealing partition is divided the heat exchange layers
Area, each subregion are connected to form closed circulation subsystem with respective water supplying pipe and recovery tube respectively.
Preferably, one end of the sealing partition is equipped with notch, separates adjacent subregion with sealing jaggy and mutually passes through
It is logical.
Further, the notch of adjacent sealing partition, which misplaces, arranges.Random length can be obtained by adding breach quantity
Heat exchanger.
Seepy material is filled in the heat exchange layers, can form pervious bed.
The backfill layer is light weight earthen backfill layer.
Technical concept of the invention are as follows: collecting technology in view of existing tunnel surrounding GEOTHERMAL WATER can not break entirely applied to tunnel
The extraction of face country rock ground temperature energy, and be laid with heat exchange pipe and will increase engineering-built cost and delay the problems such as construction period, this
Invention proposes a kind of novel ground temperature energy extractive technique.The technology is more than full section of tunnel one layer of heat exchange layers of setting, road surface
Heat exchange layers setting tunnel double-lining and just lining between, and be located at road surface below heat exchange layers be arranged above inverted arch, road
The heat exchange layers of face upper and lower are tightly connected by crossover sub, water supplying pipe and return pipe, form closed cycle heat exchange system
System extracts the ground temperature energy in tunnel surrounding by the circulation of fluid in heat exchange layers.The transfer path and length of every group of heat-exchange system
The various combination that degree can be separated by setting sealing obtains；Tunnel double-lining inner surface is laid with certain thickness insulating layer, roadbed
By light weight earthen backfill, reducing ground temperature can be lost in space between inverted arch.
In each subregion of the heat exchange layers, the sealing positioned at both sides separates elongated arrangement, and is located in the middle partition
One section of setting notch, separates adjacent subregion with sealing jaggy and is mutually communicated；The notch of sealing partition is set as staggeredly cloth
It sets, the heat exchanger of random length can be obtained by adding breach quantity.
Beneficial effects of the present invention are mainly manifested in: extracting tunnel using the heat transfer medium circulated in heat exchange layers
Ground temperature energy in country rock, the passive extractive technique for solving traditional collection GEOTHERMAL WATER can be only applied to the tunnel of rich groundwater
Road, the problem being then not suitable for for owing the tunnel educated and without underground water, the active with traditional embedded heat-exchange tube system mention
Technology is taken to compare, the water that circulates in heat exchange layers directly absorbs ground temperature energy in country rock, and heat exchange efficiency is higher.The system without
It need to be laid with heat-exchange tube, a large amount of construction cost is saved, saved the construction period.
