Description
Technical field：
The utility model is related to a kind of small-bore jacking construction method concrete duct grouting device, is mainly used in small-bore
Lubricated slurry is evenly supplied to by the device of the periphery of push pipe road four by pipeline when non-excavated jacking construction method is installed.
Background technology：
Passed through at present in pipe of concrete pipeline installation construction frequently with two kinds of mounting means, one kind is that the installation of trench excavation formula is applied
Work, another is no-dig technique pipe jacking method.Trench excavation formula installation is used in meagrely-populated place more, but in city
Then more using the construction of non-excavated jacking method inside city, non-excavated jacking construction beats vertical shaft from ground without destroying surface structures
Lower progress Durchgangshohle installation, convenient and swift cost is low.
When carrying out non-excavated jacking construction, because soil has drag effects pipeline jacking installation, needed when often constructing
Pipeline surrounding row note mud is lubricated, so as to overcome soil resistance.In general large diameter pipeline itself is with note
Hole is starched, is directly connected Grouting Pipe with injected hole, it is possible to realizes that plasma discharge lubricates, is removed after the completion of construction.But for small
Because itself internal diameter size is small for caliber pipe, after the segment distance of jacking one, operating personnel is difficult to enter into internal by slip casting
The equipment such as pipe are disassembled, therefore result in domestic small-bore pipeline almost not having using jacking construction method installation, substantially
Using excavation installation form.But with being gradually improved for Process of Urbanization Construction, old cell drainage system transformation is just inevitable
The problem of having suffered from such awkward, original pipe diameter is small and blocks and serious needs to change, it is impossible to removes and determines again
Can not be by the way of installation be excavated.
The content of the invention：
The purpose of this utility model is：Design one kind is exclusively used in small-bore jacking construction method concrete duct slip casting dress
Put, disclosure satisfy that small-bore pipeline, when non-excavated jacking construction method is installed, lubricated slurry is evenly supplied to by push pipe road four
Periphery, so as to ensure effective progress of construction.
Based on this purpose, by design and research repeatedly, we develop small-bore jacking construction method pipe of concrete
Road grouting device, its general principle is that design one saves steel pipe, and plasma discharge hole is provided with steel pipe, lead slurry pipe can directly and its
Connection, is squeezed into lubricated slurry by press device, and mud is discharged from plasma discharge hole, so that the surrounding formation wettable layer outside pipeline,
Play a part of lubrication.
Small-bore jacking construction method is with the basic structure of concrete duct grouting device by top surface annulus (1), socket steel ring
(2), transition rings (3), the slab steel cylinder (4) with plasma discharge hole, backplate ring (5), reinforcement arc plate (6), the auxiliary plate of plasma discharge (7), reinforcement
Plate one (8), stiffener plate two (9), backing plate (10) bellmouth steel ring (11), stress surface annulus (12) composition, top surface annulus (1) welding
It is integrally formed on socket steel ring (2) top, forms top power face, socket steel ring (2) is welded on transition rings (3) one end, band row
The slab steel cylinder (4) in slurry hole is welded on transition rings (3) other end, and stiffener plate one (8) and stiffener plate two (9) are welded in respectively
Slab steel cylinder (4) two ends with plasma discharge hole, particular location is itself plasma discharge hole of slab steel cylinder (4) with plasma discharge hole or so 50cm's
Distance, strengthens arc plate (6) one end and welds together with stiffener plate one (8), other end is welded into one with transition rings (3)
Body, bellmouth steel ring (11) is welded in stiffener plate two (9), and stress surface annulus (13) one end is welded on the thick plate steel with plasma discharge hole
On cylinder (4), other end welds together with bellmouth steel ring (11), forms an entirety, can be held by stress surface annulus (12)
Power is pushed up by construction, backplate ring (5) is welded on the outside of the slab steel cylinder (4) with plasma discharge hole away from transition rings (3) one end and and transition rings
(3) it is welded into one, distance of backplate ring (5) total length away from itself plasma discharge hole 25cm on the slab steel cylinder (4) with plasma discharge hole,
Backing plate (10) is welded on the place away from itself plasma discharge hole 50cm on the slab steel cylinder (4) with plasma discharge hole close to stress surface annulus (12)
Direction, in addition, the thickness of backing plate (10) is 1/2nd of backplate ring (5) thickness, the auxiliary plate of plasma discharge (7) is welded on backing plate (10)
On, and other end is welded into one with backplate ring (5).
The utility model can preferably solve small-bore pipeline when non-excavated jacking construction method is installed, it is impossible to will lubricate
Mud slurry uniform is transported to by the problem of the periphery of push pipe road four, improves the installation effectiveness of pipeline, has ensured the installation quality of pipeline.
Brief description of the drawings：
Accompanying drawing 1 is the utility model structural representation, is arranged by top surface annulus (1), socket steel ring (2), transition rings (3), band
The slab steel cylinder (4) in slurry hole, backplate ring (5), reinforcement arc plate (6), the auxiliary plate of plasma discharge (7), stiffener plate one (8), stiffener plate two
