Problems solved by technology

However, the "double-column vase pier" in the prior art is usually constructed by on-site pouring, which takes a long time and is difficult to construct. At the same time, it brings greater noise and dust pollution to the surrounding environment of the construction, and has a greater impact on urban traffic. impact, increasing the congestion of the urban road network

Embodiment 1

[0030] Such as figure 2 As shown, a specific embodiment of the present invention includes two pier body segments 2 and a pier cap segment 1, the pier body segment 2 is the main straight section of the pier, and the pier cap segment 1 is the straight-curved transition between two pier piers The junction of section 11 and a tie beam 12, two pier straight-curved transition sections 11 are respectively located at both ends of tie beam 12; the upper part of pier straight-curve transition section 11 is pier curved section 110, and pier curved section 110 gradually transitions downward It is the end section 111 of the straight line of the bridge pier.

[0031] The bottom end of the pier body segment 2 is provided with a built-in embedded sleeve 21 , and the stressed steel bars of the pier body segment protrude from the top of the pier body segment to form a pier body steel bar joint 22 .

[0032] Built-in embedded sleeves 112 are provided in the two pier straight end sections 111 a...

Embodiment 2

[0035] Such as figure 2 As shown, the direction of the arrow in the figure indicates the installation direction. The assembly construction method of the prefabricated double-column vase pier includes the following steps:

[0036] First, when the cast-in-place cap 3 is cast-in-place on the foundation of the cast-in-place pile 4 and the cast-in-place bridge cap 3, the reinforced steel bar reserved for the cap extends out of the top of the cap to form a cap reinforcement joint 31;

[0037] Secondly, the pier body segment 2 and the cap 3 are assembled and connected; the specific method is: after the pier body segment 2 and the cap 3 are closely fitted, the cap rebar joint 31 is inserted into the built-in embedded sleeve at the bottom of the pier body segment Inside the barrel 21; then, if image 3 As shown, the high-strength grouting material 5 is poured into the gap between the steel bar joint 31 of the cap and the built-in embedded sleeve 21 at the bottom of the pier body seg...

Abstract

The invention discloses a prefabricated double-column vase bridge pier and an assembling construction method thereof. The prefabricated double-column vase bridge pier comprises two pier body sections and one pier cap section, the pier body sections are bridge pier straight main sections, the pier cap section is a joint of two bridge pier straight and curve transition sections and one tie beam, the two bridge pier straight and curve transition sections are positioned at two ends of the tie beam respectively, and a bridge pier curve section is arranged on the upper portion of each bridge pier straight and curve transition section and gradually transits downwards into a bridge pier straight end section. The double-column vase bridge pier is prefabricated and divided into the pier body sections and the pier cap section, the assembling direction of the bridge pier is uniformly vertical, site construction alignment difficulty is reduced, site construction time is shortened, pollution of site construction to surrounding environments is relieved, and the influence of construction on surround traffic is minimized.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a prefabricated double-column vase pier and an assembly construction method thereof. Background technique [0002] At present, urban viaducts usually adopt the structure of "large spread arm box girder + double-column vase piers", such as figure 1 shown. This structure has a smooth shape and good integrity, and is widely used in the construction of urban viaducts. However, the "double-column vase pier" in the prior art is usually constructed by on-site pouring, which takes a long time and is difficult to construct. At the same time, it brings greater noise and dust pollution to the surrounding environment of the construction, and has a greater impact on urban traffic. impact, increasing the congestion of the urban road network. Contents of the invention [0003] In view of the above-mentioned defects of the prior art, the technical purpose of the present inventio...
