Abstract
The utility model discloses a seal gland for the prestressed cable hole in the section girder spliced plane, which is characterized in that a pre-reserved trough (5) where a seal ring (1) is pasted is provided in the opening of the channel (3) which is positioned in one side of the section girder spliced plane while a sponge seal ring (2) is pasted in the other side of the above section girder spliced plane, and the agglomerant coat (4) is used to connect the two section girder spliced planes. The utility model noticeably improves the seal condition the pre-stressed cable hole in the section girder spliced plane to effectively help the connection and close among the section girders, and reduces the water leakage and the gas permeation in the joint so as to prevent the reinforcing steel bar used in the bridge from corrosion, to help the constructors easily extract the intensity of pressure to negative pressure in the hole to make the vacuum mud jacking operation more simple and convenient as well.
Description
Technical field
The utility model relates to the sealing device that uses on a kind of engineering, particularly relates to the sealing device in beam sections Mosaic face prestressing with bond rope duct in a kind of bridge construction construction.
Background technology
The sealing in prestressed cable duct is one of difficult point of engineering in the construction of bridge subsection assembling process.Good sealing can make beam sections connect closely, fit mutually, reduces the water-permeable and air permeable at joint of bridge place, prevents corrosion of steel bar, improves the integral rigidity of bridge construction.Particularly in the bridge engineering that adopts vacuum grouting technology, can the sealing condition situation in beam sections Mosaic face prestressing with bond rope duct directly determine be evacuated to negative pressure in the mud jacking provinculum duct, and can be related to whole bridge vacuum grouting carry out smoothly.Therefore, the sealing condition that improves the cableway hole in the section assembling technology of bridge is an engineering problem anxious to be solved.
Summary of the invention
The purpose of this utility model is in order to improve the sealing condition in prestressed cable duct in the bridge subsection girder splicing, the sealing device in a kind of Mosaic face of beam sections simply and easily prestressing with bond rope duct to be provided.
In order to realize the purpose of this utility model, the technical scheme that is adopted: the sealing device in a kind of beam sections Mosaic face prestressing with bond rope duct, it is characterized in that beam sections splicing section opening of the channel place on one side is provided with preformed groove, be pasted with rubber seal in the described preformed groove, the another side of described beam sections splicing section is pasted with sponge ring, and two beam sections are spliced between the sections by adhesive coated connection.
The internal diameter of described rubber seal is greater than the internal diameter of opening of the channel.
The thickness of described sponge ring is 10mm.
Described cementing agent adopts epoxy resin, and the thickness of described epoxy adhesive coating is 1~3mm.
The beneficial effects of the utility model are, the sealing device in described beam sections Mosaic face prestressing with bond rope duct can effectively make and connect closely connectedly between the beam sections, reduces the seam crossing water-permeable and air permeable, prevents the bridge reinforcement corrosion.In construction, adopt the utility model easily pressure in the duct to be evacuated to negative pressure, make bridge construction personnel's vacuum grouting operation become very simple, convenient.

Fig. 2 is the beam sections Mosaic face prestressing with bond rope hole road sealing device before the assembly unit.
The specific embodiment
Below in conjunction with each accompanying drawing the utility model is specifically described: the sealing device in a kind of beam sections Mosaic face prestressing with bond rope duct, opening of the channel 3 places on one side are provided with preformed groove 5 at beam sections splicing section, be pasted with rubber seal 1 in the preformed groove 5, another side at described beam sections splicing section is pasted with sponge ring 2, connect by adhesive coated 4 between two beam sections splicing sections, as shown in Figure 2.The internal diameter of described rubber seal 1 is greater than the internal diameter of opening of the channel 3, paste the thick sponge ring 2 in the 10mm left and right sides in beam sections splicing section corresponding sides, sponge ring 2 thickness after rubber seal 1 compresses can be compressed to about 1mm, cementing agent enters sponge ring 2 and has played sealing function, also can stop simultaneously cementing agent to enter opening of the channel 3 and cause prestressed pore passage to stop up, cause difficulty to reeving.Described cementing agent adopts epoxy resin, and epoxy adhesive is except connecting the precast concrete sections, and between sections, transmit stressed outside, also have for the assembly unit seam provides moisture seal, prevent the effect of prestressed cable corrosion and concrete grout seepage.Brush the thick epoxy adhesive coating 4 of 1~3mm between sections, two block concrete sections to be bondd must be in contact with one another after brushing cementing agent and compress as far as possible before the cementing agent sclerosis.Compress and to realize that by the interim prestressing force of stretch-draw cementing agent can be extruded when compressing, must unnecessary cementing agent be wipeed off with scraper or other proper tools.
Claims (4)
