Abstract
The utility model discloses a be applicable to special ground shield tunnel segment ring, including splicing a plurality of sections of jurisdiction that form the ring each other, be provided with the more than one injected hole on the section of jurisdiction, the injected hole runs through perpendicularly the section of jurisdiction arc surface, be provided with the check valve on the injected hole. The utility model discloses a set up the more than one injected hole on the section of jurisdiction for slip casting is more even, can show the activity duration of reducing slip casting in the tunnel, creates the advantage for the construction in operation tunnel. Simultaneously, setting up the check valve in the injected hole, having avoided tunnel water and soil to run off through the injected hole, the concrete of having avoided simultaneously pouring into into through the injected hole flows back.
Description
Technical field
This utility model belongs to duct pieces of shield tunnel technical field, is specifically related to one and is applicable to Special Rock shield tunnel loop.
Background technology
In the Metro Tunnel of cities in China, begin to use shield to tunnel running tunnel the most more and more, use pre-
Reinforced concrete segment processed is as permanent lining, secondary lining.The quality of molding section of jurisdiction is directly connected to the quality in tunnel, and the molding matter in tunnel
Amount is directly affected by segment selection quality.This is accomplished by shield-tunneling construction grasping section of jurisdiction technical parameter and section of jurisdiction wedge shape gauge
Calculate knowledge, reach can select shield duct piece flexibly, it is ensured that gap of the shield tail and the purpose of section of jurisdiction Forming Quality, actual molding simultaneously
Tunnel location the most normally directly influences the final of tunnel and checks and accepts and use.
In currently existing scheme, the scheme of an injected hole is set in the middle of section of jurisdiction, is unfavorable for that the slip casting of tunnel perimeter section of jurisdiction is uniform.Special
It not at Special Rock layer condition (such as Muddy Bottoms figure, layer of sand liquefaction, limestone), when needing the reinforcing to base, tunnel, it is necessary to
On section of jurisdiction after punching, consolidation grouting can be implemented.Section of jurisdiction is not only damaged by section of jurisdiction punching, reduces the bearing capacity in tunnel,
And have a strong impact on tunnel structure durability.Section of jurisdiction perforate in operation tunnel, very risky, higher when running into underground flood peak
Situation, it may appear that gushing water, the engineering accident of quicksand.
Utility model content
In order to overcome above-mentioned technological deficiency, this utility model provides one to make section of jurisdiction slip casting be applicable to Special Rock shield uniformly
Tunnel duct piece.
In order to solve the problems referred to above, this utility model is achieved by techniques below scheme:
Described in the utility model it is applicable to Special Rock shield tunnel loop, including being mutually spliced to form some sections of jurisdiction of annulus,
Being provided with more than one injected hole on described section of jurisdiction, described injected hole extends vertically through on the arc surface of described section of jurisdiction, described slip casting
Non-return valve it is provided with on hole.
Further, the periphery of described injected hole is provided with reinforced steel.
Further, described section of jurisdiction includes three pieces of standard sections of jurisdiction, two pieces of adjacent sections of jurisdiction, one piece of section of jurisdiction of binding；
Described standard section of jurisdiction is spliced to form the bottom of tunneltron loop, described in bind the pipe sheet assembling top at tunneltron loop, institute
State adjacent section of jurisdiction for connecting described standard section of jurisdiction and section of jurisdiction of binding.
Further, described standard section of jurisdiction is evenly distributed with three injected holes.
Further, edge, described section of jurisdiction is provided with some axial bolts holes along described section of jurisdiction central axis direction, along footpath, described section of jurisdiction
To being provided with radial bolts hole.
Further, it is provided with sealing gasket between adjacent section of jurisdiction.
Compared with prior art, the beneficial effects of the utility model are:
This utility model is by arranging more than one injected hole on section of jurisdiction so that slip casting evenly, can significantly reduce tunnel
The activity duration of interior slip casting, the construction for operation tunnel creates favorable conditions.Meanwhile, non-return valve is set in injected hole, it is to avoid
Tunnel water and soil runs off through injected hole, avoids the concrete injected by injected hole simultaneously and refluxes.
