Description
Technical field
The utility model relates to tunnel construction technical fields, and in particular to a kind of tension dress for tunneling shield section of jurisdiction ring
It sets.
Background technique
Shield machine is a kind of rock tunnel(ling) machine using shield method.The construction method of shield is development machine paving while driving
If its " shield " of tunnel (the shield duct piece ring for referring to supportive), section of jurisdiction ring are the main mounting structures of shield-tunneling construction, be tunnel most
Internal layer barrier carries the effect for resisting earth pressure, groundwater pressure and some special loads, influences the waterproofness in tunnel
Energy and endurance quality.When shield machine enters tunnel, it is laid on tunnel inner wall since shield machine front resistance is insufficient to allow
Compressed between adjacent section of jurisdiction ring, easily cause the corresponding section of jurisdiction ring of shield drive end unit and loosen so that section of jurisdiction ring and ring it
Between gap widened, faulting of slab ends is prominent, causes leak or leakage mud phenomenon.
In order to avoid section of jurisdiction czermak space widens, therefore in shield host into needing shield before tunnel using section of jurisdiction ring tension device
Structure machine carries out connection tension into 10 ring range inner tube loop of tunnel location.
Yongfeng south is marked into the prosperous section in northwest in No. 16 lines 06 of Beijing Metro, and tension device mainly uses 14b channel steel to cooperate
Mounting head carries out longitudinal tension to the last 10 endless tube piece in tunnel respectively.Specifically, vertical along tunnel using 12 meters long 14b channel steel
4 are tensed in vault, and in the reserved hole for hoist of the preformed hole and section of jurisdiction ring that mounting head is screwed into channel steel, per pass channel steel is tensed
Device is fastened using 5 mounting heads, and channel steel processing is as shown in Figure 1.The shortcomings that being tensed using channel steel with section of jurisdiction ring:
One, 12 meters long of 14b channel steel weighs 200 kilograms, needs 5 people resultant force that could hold up, location and installation is very difficult.2, channel steel
Hole location is difficult to accurately reserve, and many times needs to cut hole or reaming again.It 3, can only be in shield machine since channel steel is an entirety
Host completely into hole and section of jurisdiction ring be all installed after can just be installed, lose the meaning of installation.
Utility model content
For the defects in the prior art, the utility model provides a kind of novel tension dress for tunneling shield section of jurisdiction ring
It sets, section of jurisdiction ring adjacent in tunnel can be tensed, and facilitate operation.
The technical scheme adopted by the utility model is a kind of tension device for tunneling shield section of jurisdiction ring, including it is solid
