The utility model discloses a beat and to establish horizontal deep - hole grouting ductule, bassoon canopy, leading ductule, half section slant deep - hole grouting ductule and form a multi -level support system at the transverse passage -way vault, eliminated vault landslide risk to through leading stratum slip casting pre -reinforcing, solidify the transverse passage -way hunch portion soil body, form a duricrust, can effectually keep vault stability of surrounding rock, control vault settlement.
Description
Technical field
This utility model relates to a kind of transverse passage-way vault advance support structure, under particularly one is positioned at the existing underground space
Transverse passage-way vault advance support structure square and close together.
Background technology
The most domestic metro industry is in the ascendant, the whole nation one, tier 2 cities flourish, shallow burial hidden digging is as one
The more construction method of science, is verified the most in practice and is widely used in Subway Tunnel construction.But big-and-middle-sized
In city, especially center, old city, urban ground skyscraper is intensive, and underground building thing is various, and pipe network is intricate, horizontal logical
Road construction faces problems with: one) transverse passage-way position selects difficulty, needs more closely to construct apart from existing underground building thing；Two)
Survey position, hole and cannot meet requirement, below existing underground building thing, geological condition cannot be verified, and ground is surveyed reported low, no
Certainty factor is many, and existing underground building thing construction the most repeatedly disturbed strata, and periphery miscellaneous fill is deep, and geological conditions is multiple
Miscellaneous, construction easily occurs the situations such as the landslide of the vault soil body, settling amount are big；Three) transverse passage-way structure closes on underground building thing, is difficult to
Possess the pre-reinforcement conditions such as surface grout injection.
Further, since construction site limits, derrick, Tu Cang, concrete batch plant, coagulation necessary to adit construction
Soil tank etc. is both needed to closing foundation ditch limit, it is difficult to meets and cheats outer preloading design requirement, there is potential safety hazard, cause center, city underground structure
The subway adit construction surrouding rock deformation of intensive position increases with Land-Subsidence Control, surrounding enviroment protection difficulty, traditional shallow embedding
Subsurface excavation method vault support form be difficult to meet transverse passage-way under complex geological condition be positioned at below the existing underground space and with both
When having the underground space nearer, construction settlement controls and the requirement of environmental conservation.
Summary of the invention
This utility model provides horizontal logical under a kind of complex geological condition for solving technical problem present in known technology
Road vault multi-level advance support structure, uses this structure can reduce Vault settlement amount, avoid the vault soil body to cave in.
This utility model is adopted the technical scheme that by solving technical problem present in known technology: one is intricately
Transverse passage-way vault advance support structure under the conditions of matter, it is characterised in that include that employing horizontal deep hole grouting grouting with small pipe is formed
Ingate arch ruggedized construction, the transverse passage-way arch that uses steel tube shed slip casting to be formed reinforces agent structure, uses and the least lead
The transverse passage-way arch that pipe slip casting is formed reinforces supplementary structure I and the palm using half section oblique deep hole grouting grouting with small pipe to be formed
Sub-face ruggedized construction and arch reinforce supplementary structure II.
Described horizontal deep hole grouting ductule has set five rings, pipe range 9 meters, hoop tube pitch 0.3 meter, adjacent ring spacing 1
Rice.
Described steel tube shed has set a ring, the long 35m of canopy, hoop tube pitch 0.3m.
Described advanced tubule length 3 meters, hoop tube pitch 0.3 meter.
Described half section oblique deep hole grouting ductule sets a ring, pipe range 8m, hoop tube pitch 9 °.
This utility model has the advantage that with good effect: by setting horizontal deep hole grouting ductule, steel tube shed, surpassing
Front ductule, half section oblique deep hole grouting ductule form a multi-level support system at transverse passage-way vault, eliminate arch
Top landslide risk, and by advanced stratum slip casting pre-reinforcement, the consolidation transverse passage-way arch soil body, form one piece of duricrust, can be effective
Holding vault adjoining rock stability, control Vault settlement.

Detailed description of the invention
For summary of the invention of the present utility model, feature and effect can be further appreciated that, hereby enumerate following example, and coordinate
Accompanying drawing describes in detail as follows:
Referring to Fig. 1～Fig. 4, transverse passage-way vault advance support structure under a kind of complex geological condition, including employing level
Ingate arch ruggedized construction, the transverse passage-way arch of employing steel tube shed 4 slip casting formation that deep hole grouting ductule 2 slip casting is formed add
Gu agent structure, the transverse passage-way arch using advanced tubule 3 slip casting to be formed are reinforced supplementary structure I and use half section oblique deeply
Solidifying of the working face structure and arch that hole slip casting ductule 5 slip casting is formed reinforce supplementary structure II.
In the present embodiment, described horizontal deep hole grouting ductule 2 has set five rings, pipe range 9 meters, hoop tube pitch 0.3
Rice, adjacent ring spacing 1 meter.Described steel tube shed 4 has set a ring, the long 35m of canopy, hoop tube pitch 0.3m.Described advanced tubule
Long 3 meters, hoop tube pitch 0.3 meter.Described half section oblique deep hole grouting ductule 5 sets a ring, pipe range 8m, hoop tube pitch
