Abstract
The utility model provides a shield constructs slip casting of quick -witted section of jurisdiction and ties, its constitution includes: slip casting is tied the body, is prolonged the pipe, slip casting is tied body lower part diameter and slightly is greater than upper portion, this internal check valve that is equipped with of slip casting bolt it encloses the fender to be equipped with rubber on the slip casting bolt inner wall, rubber encloses the fender lower extreme and is located the upper portion of check valve, rubber encloses and keeps off the surperficial even fold that has slip casting bolt body upper end is equipped with prolongs the pipe. The beneficial effects are that: the bottom is tied in the special slip casting of shield structure is the check valve, can guarantee that the thick liquid only can not advance, and the thick liquid encloses at rubber and forms a thick liquid swell under the fender effect between section of jurisdiction outer wall and country rock, forms the solid of basketball size after solidifying. This solid withstands domain section of jurisdiction as the stress point to control section of jurisdiction come -up.
Description
Technical field
This utility model is related to shield machine field, particularly relates to a kind of shield machine segment slip casting bolt.
Background technology
Now in subway work, during using shield construction, after the completion of shield cutter excavates, duct piece assembling machine enters line pipe
The assembly of piece, the digging diameter of cutterhead is more than the external diameter of section of jurisdiction, so being carried out between country rock and section of jurisdiction outer wall by the way of slip casting
The filling of gap.In slip casting, because the reasons such as serosity deadweight, stream plasticity lead to serosity to flows, lead in process of setting
Bottom slurry is many, top few so that duct piece float upward.
Utility model content
This utility model is to solve problems of the prior art, proposes a kind of shield machine segment slip casting bolt.
The technical solution of the utility model is achieved in that
A kind of shield machine segment slip casting bolt, its composition includes: slip casting bolt body, prolongs pipe, described slip casting bolt body lower part is straight
Footpath is slightly larger than top, and described slip casting bolt is originally provided with check valve in vivo, is provided with rubber enclosing, institute in described slip casting bolt inner body wall
State the top that rubber enclosing lower end is located at described check valve, there is uniform fold on described rubber enclosing surface, in described slip casting bolt
Body upper end is provided with prolongs pipe.
Described slip casting bolt body is arranged in injected hole, and described slip casting bolt body is connected with casting head.
Install with the cooperation of hole for hoist embedded part in described slip casting bolt body.
The beneficial effects of the utility model are: this utility model structure is simple, and shield special slip casting bolt bottom is check valve,
Can guarantee that serosity only import but no export；Using the dilatancy of slip casting bolt front end rubber, serosity is under the effect of rubber enclosing in section of jurisdiction outer wall
Form a serosity bulge and country rock between, after solidification, form the solid of basketball size.This solid withstands the domain as stress point
Section of jurisdiction, to control duct piece float upward.
Brief description
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or in description of the prior art the accompanying drawing of required use be briefly described it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, in the premise not paying creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation before this utility model slip casting；
Fig. 3 is the structural representation after this utility model through hole；
Fig. 4 is the structural representation after this utility model slip casting.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of paying creative work
The every other embodiment being obtained, broadly falls into the scope of this utility model protection.
A kind of shield machine segment slip casting bolt, its composition includes: slip casting bolt body 1, prolongs pipe 2, described slip casting bolt body 1 bottom
Diameter is slightly larger than top, is provided with check valve 5, is provided with rubber and encloses in described slip casting bolt inner body wall in described slip casting bolt body 1
Gear 3, described rubber enclosing 3 lower end is located at the top of described check valve 5, and there is uniform fold on described rubber enclosing 3 surface, in institute
State slip casting bolt body 1 upper end and be provided with and prolong pipe 2.
Described slip casting bolt body 1 is arranged in injected hole, and described slip casting bolt body is connected with casting head.
Install with hole for hoist embedded part 4 cooperation in described slip casting bolt body 1.
Shield special slip casting bolt its main purpose is to control subway tunnel shield method construction duct piece float upward, and its principle is:
Before slip casting, this product is put into section of jurisdiction injected hole, then be connected with casting head and carry out slip casting, shield special slip casting bolt bottom is single
To valve, can guarantee that serosity only import but no export；Using the dilatancy of slip casting bolt front end rubber, serosity is under the effect of rubber enclosing in section of jurisdiction
Form a serosity bulge between outer wall and country rock, after solidification, form the solid of basketball size.This solid withstands as stress point
Domain section of jurisdiction, to control duct piece float upward.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all this
Within the spirit of utility model and principle, any modification, equivalent substitution and improvement made etc., should be included in this utility model
Protection domain within.
