Abstract

The invention relates to a mechanical breaking construction method for shield machine achieving tunnel portal, comprising following procedures that when the shield machine achieves the outside of shield receiving well and the tip of fish cutter on the cutter head is against the outside of protective mechanism, the shield machine stops digging temporarily; the gun for chiseling the portal is hung into the shield well from the ground by mechanism, and then the gun is used to chisel the protective structure in portal range mechanically; when the portal is chiseled, the gun is hung from the shield well by mechanism and the shield machine achieves receiving well. In the invention, because the mechanical breaking construction method is used and the gun is used to chisel the protective structure in portal range directly, it is safe and rapid, the danger of portal collapse is decreased, the construction period is only one day or two days, rapid and simple process is ensured, there is no need to move in reducing speed when the shield machine achieves and tunnel construction progress is quickened. After the chiseling for portal is finished the shield machine can enter into the shield machine achieving well directly so as to achieve the purpose of invention.

Description

A kind of shield machine arrives the mechanical breaking construction method of tunnel portal
Technical field
The present invention relates to the realm of building construction, particularly relate to a kind of shield machine and arrive the job practices that tunnel portal is abolished.
Background technology
In numerous shield-tunneling construction fields, arriving portal at shield machine also prepares to appear in front of the door, after will cutting the space enclosing structure of shield structure received well, the shield structure just can go out portal and arrive shield structure received well, method in the past all is to adopt manually to abolish portal, promptly the reinforcing bar and the concrete of space enclosing structure in the portal scope is abolished, and the duration generally needs 15~20 days, because the engineering time is long, makes space enclosing structure have the risk of caving in abolishing process; In addition, adopt the method for manually abolishing portal, often when the design shield machine arrives stabilization zone length, general scope that need to consider construction 8~10m length, cause reinforcement cost higher, and shield machine 50m before arrival just needs Easy abeadl, had a strong impact on the construction speed in tunnel.
Summary of the invention
The object of the present invention is to provide a kind of efficient, saving duration, also greatly reduce simultaneously portal is cut existing risk, guarantee that shield machine arrives shield structure received well quickly and safely, cave in and provide the shield machine of effective guarantee to arrive the mechanical breaking portal job practices of tunnel portal for controlling ground preferably.
The objective of the invention is to be achieved through the following technical solutions:
(1) outside shield machine arrives shield structure received well and when the fish tail cutter point of a knife of its cutterhead withstands the outside of space enclosing structure, shield machine temporarily stops driving;
(2) will cut the required big gun machine of portal and adopt machinery to hang in the shield structure well from ground, and utilize the big gun machine in well, the space enclosing structure in the portal scope to be carried out machinery then and cut;
When (3) the big gun machine cuts portal, its should by by in the well outside well, from the order on bottom to the top of portal space enclosing structure is carried out machinery and cuts, when concrete cut finish after, directly reinforcing bar is manually cut off in utilization;
(4) when portal cut finish after, with machinery the big gun machine is hung shield structure well, and the building waste that cuts portal is cleaned out, install then and fixedly shield machine receive carriage, in the shield machine arrival received well.
The present invention is owing to adopt the job practices of mechanical breaking portal, before shield machine arrives, adopt the big gun machine directly the space enclosing structure in the portal scope to be cut, both safe and efficient, reduced the danger that portal caves in, make its construction period again as long as 1~2 day, guarantee that its technology is fast and simple, can reduce simultaneously length to 3~5m that shield machine arrives stabilization zone again greatly, and shield machine need not Easy abeadl when arriving, and has accelerated Tunnel Construction Schedule.And treat that portal cuts the back shield machine that finishes and can directly enter in the shield structure received well, reach purpose of the present invention.
Below describe realization of the present invention in detail:
The specific embodiment
Shield machine of the present invention arrives the mechanical breaking portal job practices of tunnel portal, may further comprise the steps:
(1) outside shield machine arrives shield structure received well and when the fish tail cutter point of a knife of its cutterhead withstands the outside of space enclosing structure, shield machine temporarily stops driving;
(2) will cut the required big gun machine of portal and adopt machinery to hang in the shield structure well from ground, and utilize the big gun machine in well, the space enclosing structure in the portal scope to be carried out machinery then and cut;
When (3) the big gun machine cuts portal, its should by by in the shield structure well outside well the order of direction begin to abolish, and on whole portal section, because the mechanical breaking portal is direct fast from the time, should be from the bottom of portal, space enclosing structure carried out machinery cut from bottom to top, when concrete cut finish after, directly reinforcing bar is manually cut off in utilization;
(4) when portal cut finish after, with machinery the big gun machine is hung shield structure well, and the building waste that cuts portal is cleaned out, install then and fixedly shield machine receive carriage, in the shield machine arrival received well.

Claims (1)

1, a kind of shield machine arrives the mechanical breaking construction method of tunnel portal, it is characterized in that may further comprise the steps:
(1) outside shield machine arrives shield structure received well and when the fish tail cutter point of a knife of its cutterhead withstands the outside of space enclosing structure, shield machine temporarily stops driving;
(2) will cut the required big gun machine of portal and adopt machinery to hang in the shield structure well from ground, and utilize the big gun machine in well, the space enclosing structure in the portal scope to be carried out machinery then and cut;
When (3) the big gun machine cut portal, it should be by from inside to outside, order is from bottom to top carried out machinery to space enclosing structure and cut, when concrete cut finish after, directly reinforcing bar is manually cut off in utilization;
(4) when portal cut finish after, with machinery the big gun machine is hung shield structure well, and the building waste that cuts portal is cleaned out, install then and fixedly shield machine receive carriage, in the shield machine arrival received well.
