The invention provides a heat insulation structure of human-occupied underground engineering in alpine regions, wherein a filling layer is arranged in a cavity away from a wall between a supporting layer and a lining layer; meanwhile, the high-permeability material is arranged in the filling layer of the cavity away from the wall, so that the filling layer can be arranged in underground engineering, not only can the heat preservation and insulation effect be achieved, but also underground water can be discharged, and part of heat can be carried to the outside of the hole in the drainage process.
Description
Technical field
The present invention relates to insulation construction field, specifically, more particularly to a kind of extremely frigid zones people occupies underground engineering heat preservation
Structure.
Background technology
Extremely frigid zones people occupies underground engineering due to being in ever-frozen ground stabilized zone, and daily inhabitation temperature is generally kept in 18
~22 DEG C, and peripheral rock is in permafrost, temperature is maintained at -4~0 DEG C throughout the year, for ensure the energy saving of underground engineering and
Environmental requirement optimizes traditional heat insulation layer, it is ensured that the insulation construction of setting can prevent heat loss and
Periphery frozen soil (rock) is protected not destroyed due to mankind's activity.
Underground engineering is occupied for the people that extremely frigid zones are built, internal temperature need to meet human lives' requirement, pass through constant temperature perseverance
Room equipment stablizes internal temperature and is in higher level, is influenced by outside climatic smaller.Therefore, it is simple by setting heat insulation layer
It can not meet the requirements.
Invention content
In order to solve problem of the prior art, an embodiment of the present invention provides a kind of extremely frigid zones people to occupy underground engineering heat preservation
Structure.The technical solution is as follows：
On the one hand, it provides a kind of extremely frigid zones people and occupies underground engineering insulation construction, including：Branch sheath and lining cutting layer；Institute
It states branch sheath and is set to frozen soil layer surface；Wall cavity is provided with filled layer between the branch sheath and the lining cutting layer；Institute
It states and high osmosis material is provided in filled layer；The gap for excluding liquid water is provided in the high osmosis material；Institute
State the circulation loop being provided in filled layer for artificial recharge.
Further, it is provided with concrete support in the branch sheath.
Further, it is provided with reinforced concrete lining layer in the lining cutting layer.
Further, the Thief zone material is hypertonic high-strength concrete.
The advantageous effect that technical solution provided in an embodiment of the present invention is brought is：
A kind of extremely frigid zones people provided by the invention occupies underground engineering insulation construction, by the branch sheath and the lining
Wall cavity is provided with filled layer between course；Meanwhile by setting high osmosis material in the filled layer from wall cavity,
Can be disposed in underground engineering can the effect of insulation also exclude underground water, and portion can be carried in drainage procedure

Description of the drawings
To describe the technical solutions in the embodiments of the present invention more clearly, make required in being described below to embodiment
Attached drawing is briefly described, it should be apparent that, the accompanying drawings in the following description is only some embodiments of the present invention, for
For those of ordinary skill in the art, without creative efforts, other are can also be obtained according to these attached drawings
Attached drawing.
Fig. 1 is that a kind of extremely frigid zones people of the embodiment of the present invention occupies the schematic diagram of underground engineering insulation construction；
Fig. 2 is that the extremely frigid zones people of the embodiment of the present invention occupies the diabatic process figure of underground engineering insulation construction.
Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached drawing to embodiment party of the present invention
Formula is described in further detail.
The present invention provides a kind of extremely frigid zones people to occupy underground engineering insulation construction, referring to Fig. 1, including：Branch sheath 1 and lining
Course 3；The branch sheath 1 is set to frozen soil layer surface；It is provided between the branch sheath 1 and the lining cutting layer 3 from wall cavity
Filled layer 2；High osmosis material is provided in the filled layer 2；It is provided with to exclude liquid in the high osmosis material
The gap of water；The circulation loop for artificial recharge is provided in the filled layer 2.
Further, it is provided with concrete support in the branch sheath 1.
Further, it is provided with reinforced concrete lining layer in the lining cutting layer 3.
Further, the Thief zone material is the high osmosis concrete with some strength, can be according to concrete material
The porosity of material directly judges thermal conductivity factor, such as hypertonic high-strength concrete.
Specifically, in the present embodiment, the branch sheath 1 is set to frozen soil layer surface, branch sheath, that is, country rock；Lining cutting layer is with enclosing
Between rock stratum is filled layer from wall cavity.
Required according to insulation construction, between the lining cutting of underground engineering and country rock from wall cavity fill high osmosis material
After material, effect is mainly reflected in following two aspects：First, under internal-external temperature difference, the temperature inside underground engineering is via filling
It is continuously decreased after layer until the temperature at filled layer edge is 0 DEG C, then the transition just served as a contrast by concrete, and then protects periphery frozen soil
(rock)；Second is that under this kind of heat transfer modes, it can be ensured that the temperature in filled layer is more than or equal to 0 DEG C, when environmental change generates liquid
Hole can be passed through during water to discharge it, and during low temperature underground water excludes, and can absorb heat and take away after-heat simultaneously
Discharge, it is ensured that structure, which just serves as a contrast outer frozen soil (rock) layer, can keep frozen state.If in addition, initial stage melt water can not meet take away it is surplus
During excess heat, it can be also recycled back to meet power conservation requirement by manually injecting water into formation one in high osmosis material filled layer
Road, to protect periphery frozen soil (rock), then shown in specific diabatic process See Figure 2.
The advantageous effect that technical solution provided in an embodiment of the present invention is brought is：
A kind of extremely frigid zones people provided by the invention occupies underground engineering insulation construction, by the branch sheath and the lining
Wall cavity is provided with filled layer between course；Meanwhile by setting high osmosis material in the filled layer from wall cavity,
Can be disposed in underground engineering can the effect of insulation also exclude underground water, and portion can be carried in drainage procedure
Heat is divided to exclude outside hole.
The foregoing is merely a prefered embodiment of the invention, is not intended to limit the invention, all in the spirit and principles in the present invention
Within, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention.
