Problems solved by technology

When the prestressed channel is grouted, air leakage and slurry leakage may occur in the channel, which makes it difficult to ensure the grouting density of the prestressed channel and affect the durability of the prestressed steel beam
In addition, the colloid may also be squeezed into the channel during assembly, making it difficult to wear the beam

Embodiment Construction

[0043] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.

[0044] A segmental assembled beam prestressed tunnel connector, comprising a matching section casing 1, a cast-in-place section casing 2, a one-way plug 3, a two-way plug 4, an inner snap ring 5 and a sealing ring 6.

[0045] Such as Figure 1-5 As shown, the shape of the matching section casing 1 is generally bell-shaped, and an annular flange 11 is integrally formed radially on the outer wall of the smaller diameter end, and the distance between the annular flange 11 and the outer wall is evenly spaced. Eight reinforcin...

Abstract

The invention discloses a segmental assembling beam prestressed duct connector which comprises a concrete segmental precast beam matching section sleeve, a cast-in-place section sleeve, a one-way plug, a two-way plug, an inner clamping ring and a sealing ring. By means of the duct connector, after a cementing and splicing seam of a beam section is squeezed and spliced, epoxy resin glue can be prevented from being squeezed into a duct through the sealing ring, and when duct grouting is conducted, the sealing ring can guarantee that the duct is free of water leakage and cross string hole.

Description

technical field [0001] The invention relates to the field of prestressed concrete glued and assembled beams. More specifically, it relates to a segmental assembled beam prestressed tunnel connector. Background technique [0002] The construction method of the prestressed concrete glued assembled beam is to divide the beam body into several segmental units along the longitudinal direction of the bridge for factory production, and then transport it to the bridge site segment by segment and assemble it with a mobile bracket bridge building machine or a mobile hanging basket. The segments are uniformly produced in the prefabrication field, the systematic template installation and removal are convenient, the degree of mechanization and automation is high, the template utilization rate is high, the segment manufacturing precision is high, the construction speed and quality are easy to control, and sufficient health can be obtained after the segment is prefabricated time. This co...
