In another technical solution, the chain and sprocket driving device 4 is eight, and in pairs, between chain and sprocket driving device 4
Spacing is 150mm-200mm, the same regulating mechanism of every group of chain and sprocket driving device 4.
In the actual construction process, longer to use in this kind of technical solution, eight chain and sprocket driving devices 4 are interior full
The size in sufficient chapelet face, and it usually sets one group two-by-two by chain and sprocket driving device 4, while meeting stress demand, as far as possible
The usage quantity for reducing telescoping mechanism 23 mitigates the counterweight of whole device, makes device light.The specific setting of every group of device
For same alignment pin 10 passes through the upper end of two chain and sprocket driving devices 4, and same fixed pin shaft 24 passes through two chain and sprocket driving devices 4
Lower end, and be arranged in the lower end of two chain and sprocket driving devices 4 is wrapped in by U-shaped otic placode, by telescoping mechanism 23 and U-shaped otic placode
The middle part of side is hinged, can also not have to U-shaped otic placode, directly one end of fixed pin shaft is hinged on telescoping mechanism.
In another technical solution, the upper surface of the supporting side plate 2 is provided with vertical and in parallel earth-retaining
Plate 11.
In this kind of technical solution, breast boards 11 influences applying in foundation pit for preventing the soil on bottom surface from falling into foundation pit
Work industry.
In another technical solution, the breast boards 11 is divided into muti-piece, every piece of breast boards 11 along tunneling direction
It is detachably mounted to the upper surface of corresponding supporting side plate 2, is removed when in order to need to remove by preheating embedding line.
In this kind of technical solution, during driving, laterally blocked in the preheating embedding line of tunneling direction if encountered,
It can be by the way that breast boards 11 be removed, convenient for giving way and passing through preheating embedding line.
In another technical solution, the supporting side plate 2 is divided into the first sub- backplate 12 and along tunneling direction
Two sub- backplates 13, it is hinged therebetween, enable the described second sub- backplate 13 in the direction swing perpendicular to tunneling direction.
In this kind of technical solution, when whole device is turned to, whole device is divided into hinged two parts,
The curve for being adapted to foundation pit excavates, and the swing space needed is smaller.
In another technical solution, the breast boards 11 from top to bottom successively includes:
Cage plate 14 is the board-like housing shape of lower end opening, is provided on the inner wall of the vertical side of the cage plate 14 1 more
Root is along its tunneling direction uniform intervals, the square bar 15 being vertically arranged；
Structural slab 16, the upper end can slide up and down just protrudes into the inner cavity of the cage plate 14；The structural slab 16 wraps
The more square steel plates 17 for being vertically arranged at 19 upper surface of support plate and being arranged along its tunneling direction uniform intervals are included, it is adjacent
Square steel plate 17 between by geotextiles 18 connection formed a square plate shape seamless earth-retaining face；The square steel plate 17 and square bar 15
It corresponds, the side of the square steel plate 17 against corresponding square bar 15, which is invaginated, to be formed one vertically communicated, and is cooperated with square bar 15
Guide groove, accommodate corresponding square bar 15, form the guiding slided up and down to the structural slab 16；
Support plate 19, is vertically arranged at the upper surface of corresponding supporting side plate 2, and the upper surface of the support plate 19 is used for
The upper surface of support construction plate 16, the support plate 19 is embedded with multiple rotatable balls 25, the upper end along tunneling direction
Face slightly protrudes from the upper surface of the support plate 19, and the ball 25 is corresponded with the square steel plate 17, each square steel plate 17
Lower end surface invaginate the hemispherical groove to be formed and accommodate corresponding ball 25；
A pair of of rotating plate 20, is vertically arranged in the breast boards 11 in the two sides of tunneling direction respectively, the rotating plate 20
Upper end and the lower end of the cage plate 14 of the side are hinged, enable the rotating plate 20 around hinge joint in the direction perpendicular to tunneling direction
It swings；The lower end of the rotating plate 20 is detachably mounted to the upper end of ipsilateral support plate 19, to support the cage plate 14 in institute
State the top of support plate 19；
Wherein, the spacing between the square steel plate 17 is less than the diameter of preheating embedding line.
In this kind of technical solution, when occurring preheating embedding line in front of tunneling direction, can by the rotating plate 20 of front side with
Support plate 19 is removably fixedly connected with releasing, rotating plate 20 is then rotated, so that preheating embedding line enters the upper end of support plate 19
Between face and the lower end surface of structural slab 16, the rotating plate 20 of front side is retightened with support plate 19 then and is connect, before development machine
During shifting, so that pipeline is moved to rear side from preceding side, it then will be detachable between the rotating plate of rear side 20 and support plate 19
Be fixedly connected with releasing so that the preheating embedding line is moved fully to the rear side of breast boards 11, then by the rotating plate 20 of rear side and support
Connection is retightened between plate 19, i.e. completion whole device passes through preheating embedding line.It can be pasted between square steel plate and geotextiles, or
Clip is arranged on square steel plate and sticks geotextiles by person.
Because the spacing between square steel plate 17 is less than the diameter of preheating embedding line, preheating embedding line will not be stuck in the two
Between, it, can be one on preheating embedding line outer sheath if preheating embedding line is relatively soft or diameter is less than the spacing between square steel plate 17
Hard, diameter is greater than the protection sleeve pipe of spacing between square steel plate 17, to construct and protect preheating embedding line, can specifically incite somebody to action
Protection sleeve pipe is divided into a pair of of sub-set pipe of two identical half tubular shapes, between can be clamped or removably connect
It can.
Ball 25, can smaller friction when preheating embedding line occurs mobile in 19 upper surface of support plate.Not by pre-buried
When pipeline, the lower end of square steel plate 17 can be stuck in 19 upper surface of support plate, to prevent the extruding of soil so that square steel plate 17 with
Support plate 19 is staggered, so that earth-retaining disabler.
In another technical solution, the inside of the supporting side plate 2, and the branch are goed deep into described its lower end of support plate 19
The lower end surface of fagging 19 passes through the lifting that a pair of of electric telescopic rod realizes vertical direction.
In this kind of technical solution, because the depth of preheating embedding line is different, the height of the upper surface of adjustable support plate 19
Position is spent, so that the preheating embedding line of every kind of depth can roll across on ball 25, it is convenient to reduce the resistance of preheating embedding line
Construction.

The hemispherical groove for the ball answered；
A pair of of rotating plate is vertically arranged in the breast boards in the two sides of tunneling direction, the upper end of the rotating plate and the side respectively
Cage plate lower end it is hinged, enable the rotating plate around hinge joint perpendicular to tunneling direction direction swing；The rotating plate
Lower end be detachably mounted to the upper end of ipsilateral support plate, to support the cage plate in the top of the support plate；
Wherein, the spacing between the square steel plate is less than the diameter of preheating embedding line.
9. tunneling boring chain type as claimed in claim 8 tunnels assembled development machine, which is characterized in that its lower end of the support plate is deep
Enter the inside of the supporting side plate, and the lower end surface of the support plate passes through the liter that a pair of of electric telescopic rod realizes vertical direction
Drop.
