Description
Technical field
The utility model belongs to a kind of hiding support node of the plug-in conduit of shield tunnel, is plug-in conduit and shield tunnel
Close connection, belongs to shield tunnel field.
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.
Invention 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 one kind and not destroying precast concrete section of jurisdiction, letter
Change installation procedure, quickly and effectively construct, the installation that does not influence pipeline, easy to maintain the plug-in conduit of shield tunnel hide bearing
Node.
Technical solution adopted by the utility model to solve its technical problems is：
A kind of hiding support node of the plug-in conduit of shield tunnel, including bearing, conduit and bolt, the bearing include ear
Plate, pedestal and internal thread hole, the top of the otic placode are provided with the anchor pole of the connection of the anchor pole for directly being used with concrete pipe sheet
The lower part in hole, the otic placode connects with pedestal, and internal thread hole is arranged in the bottom surface of the pedestal；It is provided with mounting hole on the conduit,
The mounting hole connects with the internal thread hole, and the bolt top passes through the mounting hole and is mounted on the internal thread hole
Interior, the bolt lower end is located at the inner cavity of the conduit, and the conduit is equipped with the operating space stretched into and installed for bolt.
Further, the hiding support node further includes backing plate, and the backing plate is located at the inner wall of the conduit, the backing plate
Through-hole connect with mounting hole, the bolt top sequentially passes through the through-hole, mounting hole and in the internal thread hole.
Further, the operating space is opening, and the openings of sizes is bigger than the bolt end, and the opening is located at
On the side opposite with mounting hole.
The beneficial effects of the utility model are mainly manifested in：
1. meeting structure design needs, solves effective connection of bearing and concrete pipe sheet from node, avoid
Secondary damage of the construction to section of jurisdiction, it is ensured that pipeline will not collide with bearing.
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.
Description of the drawings
Fig. 1 is support node elevation.
Fig. 2 is support node axonometric drawing.
Fig. 3 is bearing elevation and its sectional view.
Fig. 4 is conduit trepanning schematic diagram.
Fig. 5 is bearing and section of jurisdiction connecting node.
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 hiding support node of the plug-in conduit of shield tunnel, including bearing 1 (otic placode 11, pedestal 12
With internal thread hole 13), conduit 2, backing plate 3 and bolt 4, above four parts.The node is by the way that bearing is put into pipe of concrete
The position of piece anchor pole notch, to complete to hide the effect of bearing.
Support node (see Fig. 1 and Fig. 2) is made of four parts：Bearing 1 (see Fig. 3), conduit 2 (see Fig. 4), backing plate 3 and spiral shell
Bolt 4 (see Fig. 2).Bearing 1 is made of three parts again：Otic placode 11, pedestal 12 and internal thread hole 13 (see Fig. 3).On the otic placode 11
The bolthole opened can be connected directly with the anchor pole 5 that concrete pipe sheet uses, this is not it is ensured that destroying concrete pipe sheet 6
Under the premise of carry out erection support, to achieve the effect that smoothly to install conduit.Slotted hole 21 (see Fig. 4) is reserved on conduit 2 in advance,
Facilitate bolt 4 that connection, slotted hole is passed through to be finely tuned convenient for conduit.Internal thread hole 13 on bearing can be directly used for the installation of bolt 4,
It is simple and convenient, rapidly and effectively complete construction task.Bearing is hidden, does not expose any component outside conduit, it will not be with tunnel
Pipeline etc. in road collides.
The plug-in conduit of shield tunnel of the present embodiment hides support node, and to be a kind of be not destroying precast concrete section of jurisdiction
Premise, the novel base for supporting node being attached using existing anchor hole.
The plug-in conduit of the shield tunnel hides the installation method of support node, includes the following steps：
The first step：The size of anchor pole notch is first reserved to determine the apparent size and shape of support node according to concrete pipe sheet
Shape ensures that conduit can be close to the installation of section of jurisdiction surface.
Second step：The installation of support node, erection support node while section of jurisdiction is installed ensure the primary completion of construction,
Anchor pole erection support again need not be unclamped again.
Third walks：Slotted hole is opened up according to the position of section of jurisdiction anchor pole slot on conduit.
4th step：Conduit is fixed by bolt corresponding with bearing internal thread hole, and bolt requires that interior spiral shell cannot be longer than
Line depth+conduit thickness+plate thickness, and be screwed into depth and must meet code requirement.
