Shield is arranged at shield tail both sides and bottom, and top is opened wide, for hanging in installation for tube coupling；(5) there is earth-retaining in shield both sides above shield shell
Above plate, breast boards insertion shield and in the soil body of front, the gib of open-cut is used as.
Further preferably, the present invention is as follows：(1) rectangular shield size is according to pipe gallery size design, it is ensured that tube coupling is suitable
It is sharp assembled；(2) soil body is excavated by the cutter laid on rectangle cutterhead；(3) there is complete dreg removing system；(4) at the top of shield tail
Open wide, be available for tube coupling to hang in assembly；(5) shield back and front set breast boards, are top open cut operation and tube coupling peace
Dress provides gib；(6) shield machine provides jacking force jacking construction forward by acting on the hydraulic jack on tube coupling.
The present invention solves the city integrated problem that piping lane open-cut floor space is big, speed of application is slow.With existing skill
Art is compared, and this method mechanization degree is high, speed of application is fast, underground pipe gallery construction can be completed in narrow and small place, with tradition
Method, which is compared, can also substantially reduce ambient influnence and construction risk, and with good economy.The present invention using shield method with
The mode that cut and cover method is combined, solves the city integrated problem that piping lane open-cut floor space is big, speed of application is slow, has
More preferable adaptability, has that cut and cover method is with low cost and the advantage of shield method rapidly and efficiently concurrently, and with more preferable adaptability.

Embodiment, belongs to the scope of protection of the invention.
As illustrated in fig. 1 and 2, a kind of underground pipe gallery construction method of top open cut bottom tunneler construction, is according to following
What step was carried out：
(1) construction launching shaft 14 and received well 15, make shield complete the beginning in two vertical shafts of starting well and received well
Hair and reception；
(2) using the open type rectangular shield construction piping lane section part soil body, according to geological condition can be set cutterhead 12 or
Person uses other cutting ways, and rectangular shield is tunneled along piping lane designed lines, is acted on by oil cylinder and has laid offer on tube coupling
Thrust forward, is slagged tap using belt, and dregs is discharged by dreg removing system 10, drag-out slag car 1, and shield is arranged at the both sides of shield tail 11 and bottom
Shield, prevents dregs entrance around；
(3) piping lane top earthing uses excavator open-cut；
(4) Pipe rack use prefabricated reinforced concrete tube coupling 9, by rectangular shield rear aperture on ground
Lifting appliance is hung into assembled position, when tube coupling deviates from shield tail after installing, in tube coupling sidepiece and bottom synchronously backfill filling
After material, abjection shield tail, backfilling of earthwork is carried out at the top of tube coupling, backfill 3 is filled by backfill backhoe 2, haulage truck 4.
(5) rectangular shield is tunneled to received well along piping lane designed lines, hangs out Suporting structure, completes structure and backfill is applied
Work, construction terminates.
Wherein the side wall of starting well 14 is that reaction frame 7 is provided with carrying wall 6, starting well 6, and the both sides of cutterhead 12 are provided with breast boards
13。
In the present invention, the excavation size of the rectangular shield is consistent with piping lane Section Design size；Shield tail both sides and bottom
There is shield, top is opened wide, for hanging in installation for tube coupling；There are breast boards, breast boards insertion shield above shield shell in shield both sides
In the soil body of front, the gib of open-cut is used as.
In the present invention, piping lane section is excavated using open type rectangular shield；Piping lane top earthing uses open-cut；Tube coupling
Shield tail is put into from shield rear upper open hanger by lifting appliance and completes assembled；Shield is by acting on the jack on tube coupling
Propulsive force forward is provided.
The technological principle of the present invention：
1. digging process stratum is stable：Shield-tunneling construction keeps in a basic balance by cutterhead thrust and the face soil body；Open cut
Construction keeps soil at both sides basicly stable by shield breast boards.
2. the back-grouting 8 of tube coupling 9 ensures that stratum is stable：Installed in open type shield machine shield tail after tube coupling, in tube coupling
Testing of Grouting Material Behind Segments is used to carry out once grouting with the gap of the shield tail of shield machine；The shield tail produced along with the driving of shield machine
Gap (equivalent to shield side plate, the thickness of bottom plate), progress secondary grouting synchronous with driving.
The sequence of construction of the present invention is as follows：Construct and originate vertical shaft and received well → driving → pipe is started by starting well shield
Corridor section shield tunneling, top soil body open cut → tube coupling installation → backfilling of earthwork → shield, which continues to tunnel, completes subsequent cycle → pick
Enter to complete arrival and receive → complete whole section of piping lane construction.
Compared with prior art, the present invention also tool has the advantage that：
1) cut and cover method economy and shield method security are had concurrently, while a wide range of interference of the cut and cover method to environment is avoided,
When buried depth is larger, it is to avoid pattern foundation pit supporting structure, speed of application is faster；
