Abstract
The utility model provides a novel shield constructs section of jurisdiction articulated joint form. It is connected by the semicolumn of two adjacent sections of jurisdiction and half cylindrical groove constitutes, and the semicolumn connects as shield structure section of jurisdiction some to comprise concrete pipe equally. The semicolumn connects with the cylindrical groove surface smoothly, realizes that the shield constructs section of jurisdiction joint form for articulated, has effectually reduced the moment of flexure that the shield constructs the section of jurisdiction joint under the native water pressure effect.
Description
Technical field
This utility model belongs to shield tunnel technical field under soil water pressure effect, relates to a kind of new connected mode between the adjacent section of jurisdiction of shield tunnel.
Background technology
In recent years, along with the development of shield tunnel technology, increasing subterranean tunnel occurs in each city, and the joint of common duct pieces of shield tunnel is that screwed joint has bigger hand hole, section of jurisdiction section bearing capacity is had the biggest weakening, also needs to bolt head and hand hole are carried out anti-corrosion treatment simultaneously.And very poor without connector joint shearing resistance bending rigidity, it can not resist the Moment that imposed load causes, it is necessary to relies on the drag of ground around to reach the stress balance of self.
Summary of the invention
In order to strengthen the stability of shield duct piece joint, accelerating pipe sheet assembling speed simultaneously and reduce cost, this utility model devises a kind of novel shield duct piece joint, and this joint is greatly reduced the Moment acted on shield duct piece joint, installation process is simple, convenient later maintenance.
This utility model solves the scheme that its technical problem used: a kind of Novel shield section of jurisdiction articulated joint includes two block concrete sections of jurisdiction 1, semicolumn joint 2, semicolumn groove 3 and sealing rod 4；A described side, block concrete section of jurisdiction 1 has ganoid semicolumn protruding, another side, block concrete section of jurisdiction and semicolumn projection opposite position have ganoid semicolumn groove 3, semicolumn joint 2 is embedded in semicolumn groove 3 and is installed by articulated form, and this device is significantly increased than the common shearing resistance bending rigidity without connector joint.Shield duct piece articulated joint top and bottom paste sealing rod 4 respectively, and sealing rod seam waterproof in shield-tunneling construction seals.
Being learnt by finite element method for simulating contrast, moment of flexure suffered by shield duct piece articulated joint is much smaller than moment of flexure suffered by ordinary couplings, axle power and shearing compared with ordinary couplings without significant change.There is not pulling force in shield duct piece interannular, produces pressure by extruding, owing to contact area is sufficiently large, eliminate the hand hole impact on section of jurisdiction section bearing capacity between semicolumn joint and semicolumn groove.
The beneficial effects of the utility model are to effectively reduce the moment of flexure of shield duct piece joint under soil water pressure effect, have simple installation simultaneously, and speed of application is fast, cheap and have good bending resistance shearing strength.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model section；
In figure: 1 concrete pipe sheet；2 semicolumn joints；3 semicolumn grooves；4 sealing rods.
Detailed description of the invention
In FIG, a kind of Novel shield section of jurisdiction articulated joint includes two pieces of square concrete sections of jurisdiction 1, concrete semicolumn joint 2, semicolumn groove 3 and sealing rod 4；One side, block concrete section of jurisdiction ganoid semicolumn projection is semicolumn joint 2, another side, block concrete section of jurisdiction and semicolumn joint 2 opposite position have ganoid semicolumn groove, during shield-tunneling construction, concrete semicolumn joint 2 is embedded the articulated form realizing shield duct piece joint in semicolumn groove 3；Shield duct piece articulated joint top and bottom paste sealing rod 4 respectively.
