Description
Technical field
The present invention relates to a kind of Tunnel Engineering technical field, especially relate to a kind of annular shield or annular push pipe originate and
The portal reinforcement means reaching.
Background technology
Gradually improving and saturation along with urban ground space development, the Chinese government is building resource-conserving, environment
Under the background of friendly society, more and more the starting point is put in the exploitation of the underground space.Due to the underground space
Exploitation there is high cost, excessive risk and irreversibility, how reasonably right with construction equipment with advanced science and technology
The underground space develops and utilizes becomes the key point solving this problem.
Annular shield or annular pipe-jacking technology be a kind of differ from conventional shield or the construction technology of push bench process, it is mainly constructed
Feature is the soil body first excavating in once lining place annular section, and applies once lining, treats after tunnel holing through again to one
The secondary lined internal soil body carries out overall excavation, and applies secondary lining.Its major advantage is tunnel-shaped and size in theory
Upper unrestricted.
Conventional shield or push pipe originate and the portal reinforcement means that reaches is mainly to soil body certain limit after portal at present
Inside carry out slip casting or fender post formula is reinforced it is intended to strengthen soil strength to ensure that during export ＆ import, excavation face is stable and plays sealing
Effect.But due to being that annular section excavates when annular shield or annular jacking construction, not full face tunneling, therefore the problems referred to above can
To obtain reasonable solution, but the portal within annular hole door holder water steel ring goes along with sb. to guard him wall construction due to lacking surrounding supporting, tunnel
The internal soil body in road lacks support, all there is the overall danger caved in into active well, this will be a problem demanding prompt solution.
Content of the invention
The purpose of the present invention is exactly to overcome the defect of above-mentioned prior art presence to provide a kind of simple, safety
The portal reinforcement means that reliably annular shield or annular push pipe originate and reach.
The purpose of the present invention can be achieved through the following technical solutions:
The portal reinforcement means that a kind of annular shield or annular push pipe originate and reach, comprises the following steps:
1) apply portal sealing steel ring on starting well, received well portal enclosure wall, this portal sealing steel ring is provided with two-layer,
Its set location corresponds to inside and outside annular shield machine or annular push pipe casing body；
2) apply horizontal reinforcing anchor pole in the range of the portal sealing steel ring of inner side, and be connected with enclosure wall；
3), before annular shield or annular push pipe originate, whether judge in the concrete cover between two-layer portal sealing steel ring
There is reinforcing bar, if so, then return to step 1), again apply portal sealing steel ring, if it is not, then execution step 4)；
4), when annular shield or annular push pipe originate, annular shield machine or annular push-bench are advanced into cutterhead and are gone along with sb. to guard him with portal
Wall contacts, and cutterhead is abolished the concrete in annular region, completed to originate operation；
5) annular shield machine or annular push-bench tunnel to received well, and enclosure wall abolished by cutterhead, forms once lining；
6), after tunnel holing through, cut the enclosure wall outside portal sealing steel ring, precipitation is carried out to the soil body in tunnel, pulls out water
Flat reinforcing anchor pole, excavates the remaining soil body.
Described horizontal reinforcing anchor pole setting is multiple, and multiple horizontal reinforcing anchor poles be arranged in parallel.
The method also includes:
For short distance underpass driving, the horizontal reinforcing anchor pole in starting well and received well can be carried out to the company of drawing
Connect, improve the binding effect to portal for the anchor pole.
Horizontal reinforcing anchor pole can be applied, received well portal adopts routine side in the range of a portal sealing steel ring in starting well
Method is reinforced.
Compared with prior art, the method have the advantages that
(1) present invention utilizes this reinforcing mode of anchor pole to substitute the portal reinforcement means of traditional slip casting or fender post formula,
Waterproof and soil mass consolidation effect can be played, the connectivity of the soil body and portal building enclosure can be increased, it is to avoid portal goes along with sb. to guard him knot again
Structure causes entirety to topple due to lacking constraint, is easy to pull out simultaneously, solves annular shield or annular this new construction of push pipe
The new problem that technique is brought.
(2) this method is simple to operation, cheap, and anchor pole can be reused, have higher economy and
Promotional value.
