Specific embodiment
Example embodiment is described more fully with reference to the drawings.However, example embodiment can be with a variety of shapes
Formula is implemented, and is not understood as limited to embodiment set forth herein；On the contrary, thesing embodiments are provided so that the present invention will
Fully and completely, and by the design of example embodiment comprehensively it is communicated to those skilled in the art.Identical attached drawing in figure
Label indicates same or similar structure, thus the detailed description that will omit them.
Referring to Fig. 1 to Fig. 9, embodiment of the present invention discloses a kind of joint seal device of U-shaped Prefabricated aqueduct.The seam
Sealing device includes at least two sections U-shaped aqueduct segment 1 prefabricated by armored concrete, further includes rubber weather strip 2 and outer shield
Plate 3.The actual quantity of the aqueduct segment 1 is determined according to the physical length of aqueduct.Such as aqueduct overall length is 1000 meters, Mei Gedu
When the length of slot segment 1 is 20 meters, then the actual quantity of aqueduct segment 1 is 50.
As shown in FIG. 6 and 7, it is provided with outer chamfer face 11 at the outer rim of the end at the both ends of aqueduct segment, this is outer
The inclination angle of edged surface 11 is unlimited, and preferably 45 ° or 30 °.Thin Stainless Steel is fixed with by adhering with epoxy resin on outer fillet surface 11
The thickness of plate 12, the stainless sheet steel 12 can be selected as needed, generally preferably 1mm ~ 3.5mm.By Fig. 1, Fig. 3 and figure
6 it is found that the aqueduct segment 1 U-shaped structure on the whole, is made of the vertical wall of two sides and the arcwall of lower section, thus, In
Outer chamfer face in the vertical wall of two sides is inclined-plane, and the outer chamfer face on the arcwall of lower section is arcwall face, similarly, should
The top of stainless sheet steel 12 is inclined-plane, and lower part is arcwall face.The smooth outer surface of stainless sheet steel 12, with rubber weather strip 2
Preferable sealing effect may be implemented when contact.It is glued between the stainless sheet steel 12 and aqueduct segment 1 by epoxy resin
When connecing fixed, can the concrete wall surface by stainless sheet steel 12 reliably with aqueduct segment 1 be connected and sealed, anti-leak-stopping
Water.
Referring to Fig. 1, Fig. 2, Fig. 4, Fig. 5 and Fig. 9, outer casing 3 is the thin-slab structure made of stainless steel plate metal material, outside
Backplate 3 is removably attached in the outside wall surface of the end of two section aqueduct segments 1.The specific fixed form of outer casing 3 is unlimited, example
It can be such as mounted on by threaded fastener in the outside wall surface of aqueduct segment 1, aqueduct section can also be pressed on by hold-down mechanism etc.
In the outside wall surface of section 1.
The outer chamfer face 11 of the outer casing 3 and two aqueduct segments 1 encloses a seal chamber, can be significantly from Fig. 5
Find out, the roughly triangular structure in the cross section of the seal chamber.Rubber weather strip 2 is placed in the seal chamber.By Fig. 2, figure
4, Fig. 5 and Fig. 8 is it is found that in the present embodiment, which is the roughly triangular elongate configuration in cross section.It should
There are two side seal face 21 and a bottom surfaces 22 for the tool of rubber weather strip 2.Two side seal faces 21 of the rubber weather strip 2 respectively with
Two stainless sheet steels 12 fit, and the bottom surface 22 of the rubber weather strip 2 and the inner surface of outer casing 3 fit.It is close in rubber
The pressurization passageway 23 being arranged along the length direction of the rubber weather strip 2 is equipped in strip of paper used for sealing 2.
Pressurization passageway 23 can be closed.When the pressurization passageway 23 is closed and is passed through gas-pressurized or liquid, rubber
Sealing strip 2 can expand outward, so that the two side seal faces 21 can be combined with the sealing of stainless sheet steel 12 simultaneously.
As can be seen from the above description, the advantages of joint seal device of present embodiment, is: if rubber weather strip 2 makes
The rubber weather strip 2 as sealing material is replaced after dismantling outer casing 3 with can be convenient with seal failure after the several years, protected
This joint seal device is demonstrate,proved to the sealing effect of the seam between two aqueduct segments 1；In addition, rubber weather strip 2 is placed in
When in seal chamber, without keeping in sealing contact with stainless sheet steel 12 in advance, but in such a way that pressurization passageway 23 is pressurizeed come
Guarantee rubber weather strip 2 in conjunction with sealing between stainless sheet steel 12, on the one hand reduces in this way when assembling and disassembling outer casing 3 pair
The installation requirement of rubber weather strip 2, it is only necessary to which rubber weather strip 2 is maintained at close made of outer casing 3 and the enclosing of aqueduct segment 1
Seal it is intracavitary, operate it is more convenient, on the other hand can allow pressurization passageway 23 apply moulding pressure in a certain range
It is inside adjusted, to realize preferable sealing effect.Since the rubber weather strip 2 of present embodiment is to carry out with can be convenient
Replacement, thus the design life of single rubber weather strip 2 can be reduced, reduce rubber weather strip 2 manufacture difficulty and
Cost keeps the leakproofness and ease for maintenance of joint seal device within the scope of the entire service life of U-shaped Prefabricated aqueduct.With it is existing
The concrete structure for having technology to need to destroy aqueduct could replace sealing material and compare, and the present invention is not required to destroy the coagulation of aqueduct
Soil, it is more easy to maintain.
Pressurization passageway 23 in the present embodiment, which can penetrate through, to be set in rubber weather strip 2, i.e. the pressurization passageway 23
The both ends open both ends that are located at rubber weather strip 2 end face on.It is when in use, logical in pressurization as shown in Fig. 2 and Fig. 8
Valve 24 and pressure gauge 25 are respectively arranged at the both ends port in road 23.When valve 24 is opened, can from the valve 24 to adding
The gas or liquid of pressurization are added in pressure passageway 23.The pressure in pressurization passageway 23 can be monitored in real time in pressure gauge 25.In this hair
In bright other embodiments, one end port of the pressurization passageway 23 can be closed by plug etc., be gone here and there at other end port
Join valve 24 and pressure gauge 25.One valve 24 can also be respectively installed at the both ends port of pressurization passageway 23.Valve 24 is can to supply
Body or liquid pass through and can switch the component of pressurization passageway 23, when what is be added in pressurization passageway 23 is gas, the valve
24 can be using structures such as gas nozzles common on tire.
The gas and liquid being passed through in pressurization passageway 23, which can according to need, to be selected.For example, can be with when being passed through gas
Air or nitrogen are selected, can choose hydraulic oil etc. when being passed through liquid.
It is particularly shown and described exemplary embodiments of the present invention above.It should be understood that the present invention is not limited to institute
Disclosed embodiment, on the contrary, it is intended to cover comprising various modifications in the spirit and scope of the appended claims
And equivalent arrangements.
