Detailed Description
The prefabricated box culvert structure consists of a prefabricated box culvert, a plastic joint, a related sealing gasket and a sealing ring, is a culvert structure which is continuously performed along the length direction and can be infinitely extended theoretically, and can be used as a downward-penetrating culvert of highway engineering.
Example one
A prefabricated box culvert 10, see figure 1, is generally rectangular or square in cross-section. The whole prefabricated box culvert is of a rectangular straight tubular structure. This prefabricated box culvert structure is the even structure of wall thickness, refers to fig. 1, and four edges and corners of this prefabricated box culvert are for having the structure of chamfer, and this chamfer structure can effectual increase prefabricated box culvert's intensity.
The prefabricated box culvert is a reinforced concrete prefabricated part and has high strength and hardness.
At the corner of the prefabricated culvert 10, through holes 11 are provided that extend through both end faces and are used for installing anchor bolt assemblies 20. The perforation 11 is from the one end of prefabricated box culvert to the other end setting to be provided with the breach 12 that holds nut or bolt head and fasten in the edges and corners position of the prefabricated box culvert at this perforation place, this breach 12 sets up in edges and corners position, and uses anti-crack mortar to fill after the anchor bolt fastening, has the effect that prevents anchor bolt subassembly not hard up after this anti-crack mortar fills concurrently, and anticorrosive effect.
A groove 12 is arranged at the end face position of the prefabricated box culvert 10, the groove 12 is used for placing and accommodating a square sealing gasket, and the sealing gasket 13 is used for sealing the prefabricated box culvert at the end part thereof.
The plastic joint 30, referring to fig. 2 and 4, is a narrow rectangular or square frame-like structure as a whole, and unlike the prefabricated box culvert, is an engineering plastic member, i.e., is integrally injection molded using an engineering plastic having higher flexibility and weather resistance. This plastic joint 30 is the connecting piece of two adjacent prefabricated box culverts, make full use of thin major diameter injection moulding working of plastics easy molding, flexibility and waterproof performance advantage, and use with prefabricated box culvert pairs. The sealing rings and the annular grooves 31 for installing the sealing rings are arranged at the inserting positions of the two ends of the plastic joint, the number of the sealing rings 32 is three, and when the end part of the prefabricated box culvert is inserted into the plastic joint, the sealing rings 32 form sealing between the two parts, so that the effect of preventing water seepage is achieved.
The application of the large-diameter plastic joint can realize batch production, further reduce the construction cost of the project and has better strength than a sheet-type concrete prefabricated joint.
The inner side of the plastic joint 30, namely the middle part of the inner side, is provided with a bulge 33 which is used for limiting the insertion depth of the prefabricated box culvert on two sides, and the bulge 33 is flush with the inner side and the outer side of the prefabricated box culvert to form a basically flush structure after butt joint. The plastic joint 30 is provided at its four raised corners with bolt holes 34 for cooperation with, i.e. allowing the anchor bolts to pass through.
The sealing ring 32 and the gasket 13 in this embodiment are made of rubber, and have a sealing effect.
As a technical improvement, the sealing gasket 13 is a composite structure of rubber sheets and expansion water-stop sheets, specifically, the sealing gasket is an integrated structure formed by combining the rubber sheets and the expansion water-stop sheets which are overlapped at intervals, and the structure has the advantages that after the prefabricated box culvert is constructed and has a small amount of moisture or is affected with damp, the expansion water-stop sheets expand, the sealing density between the prefabricated box culverts is further improved in the expansion process, that is, the waterproof and anti-seepage effects of the joints can be further improved by the technical improvement. And similarly, the sealing ring is made of an expansion water-stop sealing material, so that the waterproof and anti-seepage effects are further improved.
The specific construction process is as follows:
firstly, on the good ground of handling, put prefabricated box culvert, then make a plurality of prefabricated box culverts use plastic joint to connect to use the anchor bolt subassembly to rivet fixedly in the four corners position of two adjacent prefabricated box culverts. And finally, filling and plugging the gap positions where the nuts and the bolt heads of the anchor bolt assembly are located by using mortar, and referring to fig. 3, 5 and 6.
Example two
The heating resistance wire is arranged in the plastic joint and is uniformly arranged, two electrodes are led out from the outer surface of the plastic joint, and the plastic joint is locally melted after being heated through an external power supply, so that the sealing performance of the prefabricated box culvert connecting node is further improved.
The concrete construction process is as follows: put prefabricated box culvert, then make a plurality of prefabricated box culverts use plastic joint to connect, and use anchor bolt subassembly to rivet fixedly in the four corners position of two adjacent prefabricated box culverts, rivet fixedly in-process at the pulling, give the heating resistor silk heating in the plastic joint, heat scheduled time, for example three minutes back remove the power, the stop heating, and gradual increase rivet power, at this in-process, the tip cooperation of plastic joint and prefabricated box culvert is more compact, waterproof, the leak protection effect is more. And finally, filling and plugging the gaps where the nuts and the bolt heads of the anchoring bolt assembly are located by using mortar.
The above-mentioned embodiments are only intended to describe the preferred embodiments of the present invention, but not to limit the scope of the present invention, and those skilled in the art should be able to make various modifications and improvements to the present invention without departing from the spirit of the present invention.
