Abstract
The invention discloses a waterproof structure for a shield-method tunnel anti-floating anchor rod node, which comprises a steel pipe body with a built-in seal end plate, and a water-seal steel ring arranged on the outer side surface of the steel pipe body, wherein the seal end plate is provided with an anchor rod hole; the seal end plate is welded inside the steel pipe body in a seal mode; the anchor rod penetrating through the anchor rod hole is welded with the seal end plate in a seal mode; the steel pipe body comprises a first steel pipe and a second steel pipe which are arranged coaxially; the diameter of the second steel pipe is greater than that of the first steel pipe; and one end of the second steel pipe is welded and fixed with one end of the first steel pipe through a connecting steel ring. The invention has the advantage of simple structure, is easy to operate; and compared with other waterproof devices, the invention is simpler to operate and has better waterproof effect in both pipe piece production and anchor rod construction.
Description
Technical field
The present invention relates to a kind of water proof structure of underground construction, relate in particular to a kind of water proof structure of shield tunnel anti-float anchor rod node.
Background technology
Along with scientific technological advance, a kind of shallow embedding shield tunnel engineering method has obtained more deep research and application at home and abroad.Shallow embedding shield tunnel because of its buried depth more shallow, overburden layer is thin, therefore anti-floating problem is just more outstanding.In operational phase, the measure of anti float of shallow embedding shield tunnel adopts anchor pole anti-floating more, but there is no good solution for the waterproof problem of anchor pole anti-floating node.
Chinese patent CN200820187592.2 improves the original anti-floating node of common underground structure, proposes combined type anti-float anchor rod node waterproof structure.But shallow embedding shield tunnel structure is assembled by prefabricated pipe section, foregoing invention can not directly be suitable for.
Therefore, those skilled in the art is devoted to develop a kind of water proof structure of new shield tunnel anti-float anchor rod node, meets the waterproof demand of shallow embedding shield tunnel anti-float anchor rod node.
Summary of the invention
Be different from prior art, technical problem to be solved by this invention is to provide a kind of water proof structure of the shield tunnel anti-float anchor rod node that meets shallow embedding shield tunnel anti-float anchor rod node waterproof demand.
For achieving the above object, the invention provides a kind of water proof structure of shield tunnel anti-float anchor rod node, comprise the steel tube body and the sealing steel loop that is arranged on described steel tube body lateral surface of built-in Seal end plate, on described Seal end plate, offer bolthole; Described Seal end plate welded seal is arranged on described steel tube body inside; Be located in anchor pole and described Seal end plate welded seal in described bolthole, described steel tube body comprises the first steel pipe and second steel pipe of coaxial setting, the diameter of described the second steel pipe is greater than the diameter of described the first steel pipe, and one end of described the second steel pipe is welded and fixed by the one end that connects steel loop and described the first steel pipe.
Preferably, described connection steel loop is double does described Seal end plate.
Preferably, described sealing steel loop is arranged on described the first steel pipe.
Preferably, described water proof structure also comprises the dowel that is arranged on described steel tube body lateral surface.
Preferably, described dowel is three, is evenly arranged on the same circumference of described steel tube body lateral surface.
Beneficial effect of the present invention:
The water proof structure of shield tunnel anti-float anchor rod node of the present invention, simple in structure, easy to operate, meet the waterproof demand of shield tunnel anti-float anchor rod node, and no matter be to produce or anchor bolt construction in section of jurisdiction, the more existing water-tight device of described water proof structure is simple to operate and waterproof effect is good.
Below with reference to accompanying drawing, the technique effect of design of the present invention, concrete structure and generation is described further, to understand fully object of the present invention, feature and effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is A-A place sectional structure schematic diagram in Fig. 1.
Fig. 3 is use view embodiment illustrated in fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, water proof structure one specific embodiment of shield tunnel anti-float anchor rod node of the present invention, described water proof structure comprises the steel tube body of built-in Seal end plate 9 and is arranged on the sealing steel loop 6 of steel tube body lateral surface, on Seal end plate 9, offers bolthole.
As the specific embodiment of the present embodiment, above-mentioned steel tube body comprises the first steel pipe 4 and second steel pipe 1 of coaxial setting, the diameter of the second steel pipe 1 is greater than the diameter of the first steel pipe 4, one end of the second steel pipe 1 is welded and fixed by the one end that connects steel loop 2 and the first steel pipe 4, Seal end plate 9 is weldingly fixed on and connects on steel loop 2, wherein, on Seal end plate 9, default bolthole can carry out welded seal with anchor pole and fixes; Sealing steel loop 6 is arranged on the first steel pipe 4; Described water proof structure also comprises three dowels 5 that are evenly arranged on the same circumference of the first steel pipe 4 lateral surface.
Exemplary, as shown in Figure 3, the water proof structure of a kind of shield tunnel anti-float anchor rod node of this specific embodiment is to be applied in like this on shield tunnel anti-float anchor rod node:
First, when pour into a mould the section of jurisdiction 8 in tunnel, in sealing steel loop 6 and the pre-buried section of jurisdiction 8 that is arranged on shield tunnel of dowel 5 by the steel tube body of water proof structure together with peripheral hardware.
Then, the present embodiment, in the time of application, is first located in anchor pole 3 in pre-buried steel tube body, then Seal end plate 9 is set on anchor pole 3, and a part for anchor pole 3 is stretched out from bolthole.
Finally, Seal end plate 9 is successively carried out to boxing sealing with steel tube body, anchor pole 3 respectively and fix, so far complete the application operating of the present embodiment.
In engineering practice, underground water can up permeate by anti-float anchor rod node, adopt the present invention, can suffer from the prevention of sealing steel loop 6 at the moisture in steel tube body outside, moisture in steel tube body inner side can suffer from the prevention of Seal end plate 9, thereby meets the waterproof demand of shield tunnel anti-float anchor rod node.
In other specific embodiment, connect steel loop 2 and can also doublely do Seal end plate 9.
Should be appreciated that those of ordinary skill in the art just can design according to the present invention make many modifications and variations without creative work.Therefore, all technician in the art, all should be in by the determined protection domain of claims under this invention's idea on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
