Abstract
The utility model provides a shield tunnel wears foundation ditch structure to one side, intersect and pass the shield tunnel bottom the foundation ditch including the foundation ditch with foundation ditch slope, be equipped with envelope in the foundation ditch and guan liang is gone along with sb. To guard him to the main part, shield tunnel wears two rows of SMW worker methods stake that the regional foundation pit retaining structure outside was equipped with mutually perpendicular to one side, the array orientation perpendicular to shield tunnel of method stake wherein is good at with shield tunnel one row of crossing SMW, the stake of SMW worker method is right angled triangle with envelope's cross -section, the upper portion of SMW worker method stake is equipped with the unanimous L shape guan liang rather than arraying shape, be equipped with the reinforced earth body between SMW worker's method stake and the envelope, L shape guan liang and main part are gone along with sb. To guard him to be preced with and are equipped with reinforced concrete between the roof beam and prop. The utility model provides a shield tunnel uneven problem of blade disc atress when wearing foundation pit retaining structure to one side, the construction risk is low, and, the utility model discloses can avoid forming different in nature foundation ditch when the construction, reduce foundation ditch excavation scope, reduce the whole risk of being under construction of foundation ditch.
Description
Technical field
The utility model is related to foundation pit structure, more particularly to has shield tunnel tiltedly to wear the foundation pit structure at position, belong to municipal administration,
Industrial and civil architecture technical field.
Background technology
Shield tunnel by line condition restriction tiltedly must wear foundation ditch when, generally require by building enclosure Local treatment into shield
Tunnel vertical direction, it is ensured that uniform stressed during cutterhead cutting building enclosure, the processing mode easily forms special-shaped foundation ditch and expansion is opened
Scope is dug, increases foundation pit construction risk.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of shield tunnel and tiltedly wears foundation pit structure, for current shield
Structure tunnel is tiltedly worn under conditions of foundation pit enclosure structure technical scheme disappearance, its technical feasibility, economic security.
The utility model solves the technical scheme that adopted of technical problem：A kind of shield tunnel tiltedly wears foundation pit structure, bag
Include foundation ditch and incline with foundation ditch and intersect and through the shield tunnel of the bottom of foundation ditch, building enclosure and master are provided with the foundation ditch
Body goes along with sb. to guard him Guan Liang, and the shield tunnel tiltedly wears the foundation pit enclosure structure outside in region and is provided with orthogonal two rows SMW engineering method stakes,
The orientation of the row's SMW engineering method stakes wherein intersected with the shield tunnel is perpendicular to the shield tunnel, the SMW engineering methods
Stake and the rectangular triangle in the section of the building enclosure, the top of the SMW engineering methods stake is provided with the L consistent with its spread geometry
Shape Guan Liang, is provided with soil mass consolidation between SMW engineering methods stake and the building enclosure, the L-shaped Guan Liang is gone along with sb. to guard him with the main body
Armoured concrete slab support is provided between Guan Liang.
Shield tunnel top is located at the depth of the building enclosure of the shield tunnel intersection.
The foundation ditch and internal structure construction are completed and after earthing, extract the H profile steel in SMW engineering method stakes, finally carry out shield
Structure tunnel propelling construction.
The beneficial effects of the utility model are：The utility model solves cutterhead when shield tunnel tiltedly wears foundation pit enclosure structure
Unbalance stress problem, construction risk is low, also, the utility model can avoid the formation of different in nature foundation ditch in construction, reduce foundation ditch
Scope is excavated, foundation ditch integral construction risk is reduced.

Specific embodiment
Referring to the drawings.
The utility model, including foundation ditch 1 and with foundation ditch 1 incline intersect and through the shield tunnel 2 of the bottom of the foundation ditch 1,
Building enclosure 3 being provided with the foundation ditch 1 and main body going along with sb. to guard him Guan Liang 4, shield tunnel is tiltedly worn the depth of the building enclosure 3 at position and is located at
The top of the shield tunnel 2, the shield tunnel tiltedly wears the foundation pit enclosure structure outside in region and is provided with orthogonal two rows SMW
Engineering method stake 5, wherein the orientation of the row's SMW engineering methods stake 5 intersected with the shield tunnel is perpendicular to the shield tunnel, institute
SMW engineering methods stake 5 and the rectangular triangle in the section of the building enclosure are stated, the top of SMW engineering methods stake 5 is provided with and is arranged with it
The consistent L-shaped Guan Liang 6 of shape, is provided with soil mass consolidation 7, the L-shaped Guan Liang between SMW engineering methods stake 5 and the building enclosure 3
6 and the main body go along with sb. to guard him be provided between Guan Liang 4 armoured concrete slab support 8.
The main body is gone along with sb. to guard him and be provided between Guan Liang 4 first concrete support 9, and foundation ditch bottom arranges bracing members 10, described
Basis hat, 4 and foundation ditch 1 internal structure 11 construction finish after top backfill earthing 12.
Concrete construction method of the present utility model is as follows：
（1）Shield tunnel tiltedly wears the foundation pit enclosure structure construction depth in region to shield tunnel top 1m.
（2）Shield tunnel tiltedly wears the foundation pit enclosure structure outside in region and forms a right angle three using SMW engineering methods pile driving construction
It is angular, and ensure the one side intersected with shield tunnel perpendicular to shield tunnel.
（3）The soil body in Delta Region that the stake of SMW engineering methods is formed with foundation pit enclosure structure is reinforced, and reinforcement depth is hole
3m below bottom, is attached between ground SMW engineering methods stake and foundation pit enclosure structure using armoured concrete slab.
（4）Then carry out excavation and return to build internal structure, after the completion of band foundation pit construction, extract SMW engineering method stakes
Interior H profile steel, finally carries out shield tunnel propelling construction.
