Description
Technical field
The utility model belongs to shield tunnel neck, and in particular to is used for close-connected the one of plug-in conduit and shield tunnel
The plug-in conduit of kind shield tunnel half hides support node.
Background technology
Shield-tunneling construction is that precast concrete section of jurisdiction is gradually mounted on to tunnel surrounding during mechanically-propelled, prevents tunnel
Road caves in.Shield tunnel gut line and the conventional method of equipment installation are by expansion bolt come fixing bracket.Installation expansion
It needs to drill when bolt, this hole causes to damage to precast concrete pipe sector-meeting, destroys its structure, influences its stress, while also depositing
Percolating water hidden danger.Expansion bolt will produce loosening under dynamic loading, influence its anchor force.Applicant earlier application one kind
The plug-in conduit of shield tunnel hides bearing section, and backing plate and bolt are located at the inner cavity of conduit, sets suitable for the loads such as pipeline are smaller
Standby can use hides bearing installation fixation.But the equipment such as escape route it is larger when, hide bearing by the built-in limitation of bolt
It cannot be satisfied requirement.It needs a kind of to increase stress, and exposed bearing that cannot be too many at this time.
Utility model content
In order to overcome the destruction precast concrete section of jurisdiction of the plug-in conduit of existing shield tunnel, installation procedure be complicated, construction compared with
Slowly the installation of pipeline, the deficiency of troublesome maintenance, are influenced, the utility model provides a kind of half hiding branch of the plug-in conduit of shield tunnel
Block node, premised on not destroying precast concrete section of jurisdiction, the novel base for supporting node being attached using existing anchor hole should
Joints are big, and exposed component is few.
Technical solution adopted by the utility model to solve its technical problems is：
A kind of half hiding support node of the plug-in conduit of shield tunnel, including bearing, conduit, bolt and backing plate, the bearing
Including otic placode, pedestal and internal thread hole, the top of the otic placode is provided with the connection of the anchor pole for directly being used with concrete pipe sheet
Bolthole, the lower part of the otic placode connects with pedestal, and internal thread hole is arranged in the bottom surface of the pedestal；Peace is provided on the conduit
Through-hole is filled,
The installation through-hole connects with the internal thread hole；The backing plate is equipped with through-hole and the outside positioned at the conduit,
The backing plate through-hole connects with the installation through-hole of conduit, and the front end of the bolt sequentially passes through the through-hole and conduit of the backing plate
Installation through-hole and in the internal thread hole, the bolt end is located at the outside of the conduit and backing plate.
The technical principle that the above-mentioned plug-in conduit of shield tunnel half hides support node is：The bolthole opened in support lug can
The anchor pole connection directly used with concrete pipe sheet, ensure that and carry out erection support under the premise of not destroying concrete pipe sheet, prop up
The internal thread hole of seat connects with the mounting hole of conduit, and then the front end of bolt sequentially passes through the installation of the through-hole and conduit of backing plate
Through-hole is simultaneously mounted in internal thread hole, to achieve the effect that smoothly to install conduit.Half hides bearing due to only revealing outside conduit
Go out one piece of backing plate, a bolt head, it is considerably less on the headroom influence in tunnel, but its stress-bearing capability increases very much, can meet
The installation of the big component such as life channel.
Further, the cross-sectional length of the backing plate is more than the opening of conduit and the length less than or equal to conduit section.
Further, the conduit installation through-hole is slotted hole.The design of slotted hole is finely tuned convenient for conduit.
The beneficial effects of the utility model are mainly manifested in：
1, structure design needs are met, effective connection of bearing and concrete pipe sheet is solved from node, avoids
Damage of the secondary construction to section of jurisdiction, half hiding bearing only expose one piece of backing plate, a bolt head, in tunnel outside conduit
Headroom influence it is considerably less, but its stress-bearing capability increase can much meet life channel etc. greatly component installation.
2,2, construction cost is low.The expense for reducing secondary trepanning avoids the maintenance cost caused by trepanning.
3, construction efficiency is high.The bearing can be installed along with when installing section of jurisdiction in the notch of section of jurisdiction, and the later stage can directly pacify
Dress.The method is simple and practicable, and effect is apparent.

Specific implementation mode
The utility model is further described below in conjunction with the accompanying drawings.
Referring to Fig.1~Fig. 5, a kind of half hiding support node of the plug-in conduit of shield tunnel, including bearing 1, conduit 2, bolt 4
With backing plate 3, the bearing includes otic placode 11, pedestal 12, internal thread hole 13, and the top of the otic placode is provided with for directly with coagulation
The bolthole 14 for the anchor pole connection that native section of jurisdiction uses, the lower part of the otic placode connect with pedestal, in the bottom surface setting of the pedestal
Threaded hole；Installation through-hole 21 is provided on the conduit, the installation through-hole connects with the internal thread hole；The backing plate is equipped with logical
Hole 31 and the outside for being located at the conduit, the through-hole of the backing plate and connecting for conduit, the front end of the bolt sequentially pass through institute
State the through-hole of backing plate and the mounting hole of conduit and in the internal thread hole, the bolt end be located at the conduit with
The outside of backing plate.
The technical principle that the above-mentioned plug-in conduit of shield tunnel half hides support node is：The bolthole 14 opened in support lug
It can directly be connected with the anchor pole 5 that concrete pipe sheet uses, ensure that and branch is installed under the premise of not destroying concrete pipe sheet 6
Seat, the internal thread hole of bearing connect with the mounting hole of conduit, and then the front end of bolt sequentially passes through the through-hole and conduit of backing plate
Installation through-hole and in the internal thread hole, to achieve the effect that smoothly to install conduit.Half hides bearing due in conduit
It is outer only to expose one piece of backing plate, a bolt head, it is considerably less on the headroom influence in tunnel, but its stress-bearing capability increases very much,
The installation of the big component such as life channel can be met.
The plug-in conduit of the shield tunnel half hides the installation method of support node, includes the following steps：
The first step：The size of anchor pole notch first reserved according to concrete pipe sheet to determine the apparent size and shape of bearing,
Ensure that conduit can be close to the installation of section of jurisdiction surface.
Second step：The installation of bearing, when section of jurisdiction is installed, erection support, the primary completion of guarantee construction need not weigh simultaneously
It is new to unclamp anchor pole erection support again.
Third walks：Slotted hole is opened up according to the position of section of jurisdiction anchor pole slot on conduit.
