The utility model discloses a TBM tunnel lining section of jurisdiction provides support and location when assembling, can effectual improvement TBM tunnel lining section of jurisdiction speed of assembling, the wrong platform phenomenon that produces when reducing pipe ring and assembling has guaranteed section of jurisdiction installation quality when improving TBM tunnel lining section of jurisdiction installation progress.
Description
Technical Field
The utility model relates to a support and location in the tunnel lining section of jurisdiction work progress especially relate to the TBM tunnel lining section of jurisdiction that possesses the auxiliary stay location.
Background
Under the influence of the excavation principle of a TBM (tunnel boring machine) and a rear support, the diameter of an excavated hole is slightly larger than the outer diameter of a duct piece. The assembling of the duct piece is carried out under the assistance of no duct piece supporting and positioning device, and on one hand, the influence of the gap between the rock wall and the outer diameter of the duct piece (the later stage of the gap is filled with pea gravel and grouting) and the excavation flatness is caused, so that the adjacent duct pieces have great difficulty in circumferential and radial connection, and great influence is brought to the assembling efficiency of the duct pieces. On the other hand, the assembled duct piece is difficult to be flushed with the inner wall of the duct piece of the previous ring, so that the staggered platform is easily generated between the duct piece ring and the ring, and the assembling quality is influenced.
Disclosure of Invention
An object of the utility model is to provide a TBM tunnel lining section of jurisdiction that possesses auxiliary stay location.
In order to achieve the above purpose, the utility model adopts the following technical proposal:
possesses TBM tunnel lining section of jurisdiction of auxiliary stay location, including the section of jurisdiction body, this internal radial pre-buried internal thread sleeve pipe that has of section of jurisdiction, the inside and outside cambered surface that the internal thread sheathed tube both ends mouth of pipe extended to the section of jurisdiction body respectively, and threaded connection has the bolt in the internal thread sleeve pipe, the bolt head of bolt is located the interior cambered surface side of section of jurisdiction body.
The number of the internal thread sleeves is one or more.
The nominal diameter of the thread of the internal thread sleeve is more than or equal to M30.
The utility model discloses a TBM tunnel lining section of jurisdiction provides support and location when assembling, can effectual improvement TBM tunnel lining section of jurisdiction speed of assembling, the wrong platform phenomenon that produces when reducing pipe ring and assembling has guaranteed section of jurisdiction installation quality when improving TBM tunnel lining section of jurisdiction installation progress.

Detailed Description
As shown in fig. 1-3, possess TBM tunnel lining section of jurisdiction of auxiliary stay location, including the section of jurisdiction body, when the section of jurisdiction body is made, to section of jurisdiction body 1, 2, 3 that lie in a ring canal piece lower part and both sides, respectively during the prefabrication along two internal thread bushing 4 of axial central line 9 intervals pre-buried in every section of jurisdiction body 1, 2, 3, every internal thread bushing 4 all is along radially pre-buried, every internal thread bushing 4's both ends mouth of pipe extends to the interior, extrados of section of jurisdiction body 1, 2, 3 respectively, internal thread bushing 4's nominal diameter is greater than or equal to M30. The pipe piece bodies 1, 2 and 3 are blocked by plugs in the storage and transportation process so as to prevent impurities from entering; when a ring canal piece is assembled, the segment body 5 positioned at the top of the ring canal piece does not need to embed an internal thread sleeve because of the self-weight.
When a ring of pipe pieces are assembled, a bolt 6 is screwed in the internal thread sleeve 4 of the pipe piece bodies 1, 2 and 3 positioned at the lower part and two sides of the ring of pipe pieces respectively, and the bolt head of the bolt 6 is positioned on the inner arc surface side of the pipe piece body; after the ring segment is assembled in place, the bolt head of the adjusting bolt 6 enables the end part 7 of the screw rod to extend out of the outer arc surface of the segment body 1, 2 or 3 to be in contact with the rock wall 8, the length of the outer arc surface of the segment body 1, 2 or 3 is adjusted to achieve the supporting and positioning effects, and the purpose of flushing the inner wall of the adjacent ring segment after assembly is achieved.
Claims (3)
1. The utility model provides a TBM tunnel lining section of jurisdiction that possesses auxiliary stay location, includes the section of jurisdiction body, its characterized in that: an internal thread sleeve is pre-embedded in the segment body along the radial direction, pipe orifices at two ends of the internal thread sleeve respectively extend to the inner cambered surface and the outer cambered surface of the segment body, a bolt is connected with the internal thread sleeve in a threaded manner, and the bolt head of the bolt is positioned on the inner cambered surface side of the segment body.
2. The TBM tunnel lining segment with auxiliary supporting and positioning functions as claimed in claim 1, wherein: the number of the internal thread sleeves is one or more.
3. The TBM tunnel lining segment with auxiliary supporting and positioning functions as claimed in claim 1 or 2, wherein: the nominal diameter of the thread of the internal thread sleeve is more than or equal to M30.
