A kind of large section earth pressure balance box culvert development machine, it is characterised in that the forepart of the box culvert development machine is excavation
Cabin, the excavation cabin meet the rectangular section in native face, at least three groups of cutterheads are distributed with thereon, the rectangle is adapted to including diameter
Several first cutterheads of profile height, be arranged between adjacent first cutterhead several second cutterheads of gap and
Positioned at several 3rd cutterheads of the rectangular cross section edge, the model that cutterhead described in each group does not cover on the rectangular cross section
It encloses place and is provided with giant and deflector.
The covering area of cut of cutterhead described in each group at least accounts for more than the 92% of the rectangular cross section area.
The housing afterbody of the box culvert development machine is connected with a section concrete box culvert, the concrete box culvert and the box culvert
The housing of development machine pours integrally.
The housing of the box culvert development machine is formed by least two sub- housing parallel combinations, the adjacent sub- housing
Between using gusset piece dock.
The bottom for excavating cabin has a soil outlet, and the soil outlet is connected with screw conveyor.
The utility model has the advantages that several groups of cutterheads and giant are set and led by excavating cabin Ying Tu faces at it
Flowing plate is so as to fulfill the excavation to super large rectangular cross section, instead of original grid type pick in large section tunnel work progress
Into machine or hand excavation's construction, surface subsidence can be efficiently controlled, reduces construction risk, improves construction driving speed.

Specific embodiment
The feature of the utility model and other correlated characteristics are made further specifically by embodiment below in conjunction with attached drawing
It is bright, in order to the understanding of technical staff of the same trade：
Such as Fig. 1-3, mark 1-15 is respectively in figure：First cutterhead 1, the second cutterhead 2, the 3rd cutterhead 3, deflector 4, high pressure
Hydraulic giant 5, plastron 6, top breast boards 7, housing 8, screw conveyor 9, concrete box culvert 10, excavation cabin 11, soil outlet 12, connection
Plate 13, reinforcing plate 14, sub- housing 15.
Embodiment：As shown in Figure 1, 2, 3, the present embodiment is specifically related to a kind of large section earth pressure balance box culvert development machine,
The box culvert development machine includes housing 8 and is connected to the first section concrete box culvert 10 of 8 afterbody of housing, and it is whole that the two pours composition one
Body, the entirety of box culvert development machine are constructed in super large rectangular cross section.
As shown in Figure 1, 2, 3, the housing 8 of box culvert development machine is designed using sectional type, is specifically by four in the present embodiment
What sub- 15 parallel combination of housing formed, it docks and is welded and fixed by gusset piece 13 between adjacent sub- housing 15, every sub- shell
The design size height of body 15 is controlled within 4200mm, to meet the transport requirement of urban road.In addition, in order to increase housing
8 rigidity, uniform intervals set several reinforcing plates 14 on each wall surface of housing 8.
As shown in Figure 1, 2, cabin 11 is excavated in the forepart of box culvert development machine housing 8 for one, and the excavation cabin 11 is by plastron 6, top
Breast boards 7 and several groups of cutterheads enclose.In the present embodiment, that excavates cabin 11 meets the rectangular section in native face, sets thereon
Three groups of cutterheads not of uniform size are equipped with, wherein, first group of cutterhead includes several first cutterheads 1, and the first cutterhead 1 is circular machete
Disk, diameter is identical with the height for excavating cabin 11, and each first cutterhead 1 arranges setting successively in the horizontal direction, cuts covering
Area occupies the higher proportion of rectangular cross section；Second group of cutterhead includes several second small-sized cutterheads 2, and each small-sized second
Cutterhead 2 is arranged in the gap between the first adjacent cutterhead 1, and covering is not cut so as to further compensate for the first cutterhead 1 of covering
Region；3rd group of cutterhead includes several the 3rd small-sized cutterheads 3, and each the 3rd small-sized cutterhead 3 is arranged on rectangular cross section
