Abstract
The utility model discloses a circumferential connecting structure between shield segments with unequal wall thicknesses, which comprises a thin-wall shield segment and a thick-wall shield segment which are welded together along the circumferential direction; stainless steel angle iron is pre-embedded on the circumferential joint surface and the inner ring surface of one side, connected with the thick-wall shield segment, of the thin-wall shield segment; the two sides of the stainless steel angle iron are respectively adapted to the corresponding annular connecting surface shape and the inner annular surface shape; a stainless steel plate is pre-embedded on the circumferential joint surface at one side of the thick-wall shield segment, which is connected with the thin-wall shield segment, and the shape of the stainless steel plate is adapted to the shape of the circumferential joint surface; the welded welding line is corner welding and is arranged along a stainless steel annular joint of the annular joint surface of the thin-wall shield segment and the annular joint surface of the thick-wall shield segment. The utility model discloses the advantage lies in successfully having solved the stagnant water of adjacent two rings wall thickness shield structure section of jurisdiction that varies, only starching problem, construction convenience simultaneously, the joint effect is better.
Description
Technical Field
The utility model relates to a shield constructs the hoop connection of section of jurisdiction, especially relates to the hoop connection structure between the unequal wall thickness shield constructs the section of jurisdiction.
Background
The tunnel that adopts shield formula entry driving machine to be under construction generally adopts lining cutting of the section of jurisdiction of the same form, nevertheless along with the appearance of more and more big buried depth, long distance tunnel, the structure atress condition of tunnel is more and more complicated, for the needs that satisfy the structure safety of tunnel and construction, the tunnel lining cutting needs adopt the section of jurisdiction of different forms, this wherein just includes the difference of section of jurisdiction thickness. The pipe piece with the same thickness is generally provided with the water stopping groove at the same position on the outer side or the inner side of the pipe piece, and when the pipe piece is installed, water-swelling rubber is placed in the groove to achieve the sealing connection between each two ring pipe pieces, so that the water stopping and slurry stopping effects are achieved. But when two ring canal pieces wall thickness that are connected are different, the relative position in its stagnant water groove is generally different, and at this moment, the connection between the different wall thickness section of jurisdiction just can not utilize to put in the stagnant water groove and met water inflation rubber and realize to the stagnant water or the thick liquid that have influenced between the shield structure section of jurisdiction.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a wall thickness that varies shield constructs hoop connection structure between section of jurisdiction.
In order to achieve the above purpose, the utility model adopts the following technical proposal:
the utility model discloses a circumferential connecting structure between shield segments with unequal wall thickness, which comprises a thin-wall shield segment and a thick-wall shield segment welded together along the circumferential direction; stainless steel angle iron is pre-embedded on the circumferential joint surface and the inner ring surface of one side, connected with the thick-wall shield segment, of the thin-wall shield segment; the two sides of the stainless steel angle iron are respectively adapted to the corresponding annular connecting surface shape and the inner annular surface shape; a stainless steel plate is pre-embedded on the circumferential joint surface at one side of the thick-wall shield segment, which is connected with the thin-wall shield segment, and the shape of the stainless steel plate is adapted to the shape of the circumferential joint surface; the welded welding line is corner welding and is arranged along a stainless steel annular joint of the annular joint surface of the thin-wall shield segment and the annular joint surface of the thick-wall shield segment.
The single-side width of the stainless steel angle iron is 5-15 cm, and the thickness of the stainless steel angle iron is 5-10 mm; the width of the stainless steel plate is 10 cm-20 cm, and the thickness of the stainless steel plate is 5 mm-10 mm.
The utility model discloses the advantage lies in successfully having solved the stagnant water of adjacent two rings wall thickness shield structure section of jurisdiction that varies, only starching problem, construction convenience simultaneously, the joint effect is better.

Detailed Description
As shown in fig. 1-3, the circumferential connecting structure between the segments of the shield with unequal wall thickness is implemented according to the following steps:
firstly, when a thin-wall shield segment 1 is prefabricated, a stainless steel angle iron 1.1 with the thickness of 5-10 mm and the single-side width of 5-15 cm is pre-embedded on the annular connection surface and the inner annular surface which are connected with the thick-wall shield segment 2, and the shape of the stainless steel angle iron 1.1 is adapted to the shape of the annular connection surface and the shape of the inner annular surface of the thin-wall shield segment 1;
secondly, when the thick-wall shield segment 2 is prefabricated, a stainless steel plate 2.1 with the thickness of 5-10 mm and the width of 10-20 cm is pre-embedded on the annular connection surface connected with the thin-wall shield segment 1, and the shape of the stainless steel plate 2.1 is adapted to the shape of the annular connection surface of the thick-wall shield segment 2;
and thirdly, after prefabricating the thin-wall shield segment 1 and the thick-wall shield segment 2, enabling the thin-wall shield segment 1 and the thick-wall shield segment 2 to enter a tunnel to be installed, enabling stainless steel angle iron 1.1 on the annular connection surface of the thin-wall shield segment 1 to be in contact with stainless steel plate 2.1 on the annular connection surface of the thick-wall shield segment 2, after the segment is installed and a grouting process is completed, and after the segment is stably installed, performing fillet welding 3 at the stainless steel annular connection surface of the thin-wall shield segment 1 and the annular connection surface of the thick-wall shield segment 2 to the connection joint, so that sealing connection between the shield segments with different wall.
