Description

A kind of horizontal frozen and pipe canopy joint reinforcement metro shield export & import termination
Technical field
The utility model relates to a kind of horizontal frozen and pipe canopy joint reinforcement technical field, is specially a kind of horizontal frozen and pipe canopy joint reinforcement metro shield export & import termination.
Background technology
Pipe canopy is mainly used in having in the weak broken wall rock Tunnel Engineering of relatively strict limitation requirement for country rock distortion and surface subsidence, such as weakness, grit stratum and soft rock, talus, shatter belt location camber effect, the pipe canopy of construction supports with front of tunnel heading country rock and is supported for fulcrum with rear country rock in advance, form a beam formula structure, the two forms the shell-like structure around tunnel profile, can effectively suppress wall rock loosening and collapse, reinforce effect, grouting serous fluid is pressed in wall-rock crack through tube wall hole, make loose ground cementing, consolidation, thus improve the physico-mechanical properties of weakness (fragmentation) country rock, enhance country rock from ability to bear, reach the object of reinforcing pipe canopy peripheral rock, annular groove effect, the blast impulse wave traveling of the quick-fried generation of tunnel face and detonation gas expansion are reflected after meeting pipe canopy intensive annular hole slot, absorb or diffraction, greatly reduce surrounding rock failure degree and disturbance scope that negative drawing ripple causes, guarantee construction safety, pipe canopy support rigidity is bigger, as again caved in during construction, the slag that collapses also is drop on the rock slag of Guan Peng top, play shock absorption, even if pipe canopy unstability, its destruction is also slower, freezing technology utilizes artificial cooling technology, make the water freezing in stratum, natural ground is become frozen soil, increase its strength and stability, contacting of isolated underground water and underground works, to carry out the special constructional technique of underground works driving and masonry construction under the protection of freezing wall, its essence is and utilize artificial cooling Iterim Change rock and soil properties with consolidating stratum, freezing wall is a kind of temporary support structures, after permanent supporting is formed, stopping is freezed, melting, geotechnical engineering is freezed Refrigeration Technique and is usually utilized material to turn into gaseous state from liquid state, namely the endothermic thermal event of vaporescence completes, its refrigeration system mainly with ammonia as refrigeration working medium, in order to make ammonia turn into gaseous state from liquid state, liquid state is turned into again from gaseous state, so circulation carries out, whole refrigeration system is by the ammonia recycle system, brine circulation system and cooling water recirculation system 3 systemic circulation are formed, existing Technical comparing is single, respectively there is excellent lacking can not meet different demand.
Practical novel content
The purpose of this utility model is to provide a kind of horizontal frozen and pipe canopy joint reinforcement metro shield export & import termination, to solve in above-mentioned background technology the problem proposed.
For achieving the above object, the utility model provides a kind of horizontal frozen of following technical scheme and pipe canopy joint reinforcement metro shield export & import termination, comprise rectangle and freeze district, export & import inwall, inwall adds fixing apparatus, anti-pool, slip casting district, freezing hole, district installed by pipe canopy, pipe canopy, voltage discharging area, relief hole and thermometer hole, described rectangle freezes to be provided with export & import wall inside district, described export & import inner wall outside is provided with and adds inwall fixing apparatus and anti-pool, described anti-pool is connected with the slip casting district in outside, it is provided with freezing hole inside described slip casting district, described slip casting district installs district with pipe canopy and is connected, described pipe canopy is installed and is provided with pipe canopy inside district, described pipe canopy is installed district and is connected with voltage discharging area, outside, relief hole and thermometer hole are installed inside described voltage discharging area.
Preferably, described thermometer hole is distributed in slip casting district and voltage discharging area.
Preferably, described pipe canopy is provided with altogether 12.
Preferably, described slip casting district, pipe canopy install district and voltage discharging area formation semi-circular structure.
Preferably, described import and export inwall forms hexagonal structure.
Compared with prior art, the beneficial effects of the utility model are: this horizontal frozen and pipe canopy joint reinforcement metro shield export & import end structure are simple, operation easy construction, production cost reduces, freeze and pipe canopy joint reinforcement makes export & import more firm, for subsequent construction improves guarantee, it is to increase working efficiency, increase economic benefit.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1, rectangle freezes district, 2, export & import inwall, 3, inwall add fixing apparatus, 4, anti-pool, 5, slip casting district, 6, freezing hole, 7, pipe canopy district is installed, 8, Guan Peng, 9, voltage discharging area, 10, relief hole, 11, thermometer hole.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described embodiment is only the utility model part embodiment, instead of whole embodiments. Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model provides a kind of technical scheme: a kind of horizontal frozen and pipe canopy joint reinforcement metro shield export & import termination, comprise rectangle and freeze district 1, export & import inwall 2, inwall adds fixing apparatus 3, anti-pool 4, slip casting district 5, freezing hole 6, district 7 installed by pipe canopy, pipe canopy 8, voltage discharging area 9, relief hole 10 and thermometer hole 11, rectangle freezes to be provided with inside district 1 export & import inwall 2, export & import inwall 2 forms hexagonal structure, save space like this, inwall is installed outside export & import inwall 2 and adds fixing apparatus 3 and anti-pool 4, anti-pool 4 is connected with the slip casting district 5 in outside, freezing hole 6 it is provided with inside slip casting district 5, slip casting district 5 installs district 7 with pipe canopy and is connected, pipe canopy is installed and is provided with pipe canopy 8 inside district 7, pipe canopy is installed district 7 and is connected with voltage discharging area, outside 9, slip casting district 5, district 7 installed by pipe canopy and voltage discharging area 9 forms semi-circular structure, soil layer on the upside of export & import can be made so more firm, relief hole 10 and thermometer hole 11 are installed inside voltage discharging area 9.
