Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings and the following embodiments.

[0036] The first aspect of the embodiment of the present invention provides a construction method for a prefabricated bridge pier column and cap, including the following steps:

[0037] Step 1: Prefabricate the piers 20 .

[0038] Step 2: At the preset installation position of the pier column 20, fabricate the cap 10 with the cap reserved slot 11 on the upper end.

[0039] Step 3: Install the pier column 20 into the reserved platform slot 11 of the platform 10 .

[0040] Step 4: Press the grouting material 30 into the reserved slot 11 of the platform until the grouting material 30 is flush with the opening of the reserved slot 11 of the platform.

[0041] Wherein, step 1 includes: the first part 21 and the second part 22 of the prefabricated pier column 20, the outer diameter of the first part 21 is smaller than the second part 22, and t...

Abstract

The invention provides a construction method for an assembly type bridge pier column and a bearing platform, and relates to the technical field of assembly type bridge construction. The method comprises the steps: 1, prefabricating the pier column; 2, manufacturing the bearing platform with a bearing platform reserved slot hole on the upper end face; 3, installing the pier column into the bearingplatform reserved slot hole; 4, pressing grouting materials into the bearing platform reserved slot hole; wherein step 1 comprises the substeps of prefabricating a first part and a second part of thepier column, wherein the outer diameter of the first part is smaller than that of the second part, and connecting the first part to the lower end surface of the second part; the step 1 further comprises the substep of arranging a transverse anchoring head and a vertical anchoring head; and in the step 3, the first part of the pier column is installed into the bearing platform reserved slot hole until the lower end face of the second part is not higher than the opening depth of the bearing platform reserved slot hole. The construction method is convenient and fast to construct, can enable the connection of the pier column and the bearing platform to be stable, and is suitable for wide-range popularization.

Description

technical field [0001] The invention relates to the technical field of prefabricated bridges, in particular to a connection structure for pier columns and caps of prefabricated bridges and a construction method thereof. Background technique [0002] The prefabricated bridge is a new type of bridge construction mode, in which the connection between the cap and the pier column is extremely important to the overall construction of the bridge. However, the existing connection methods of caps and pier columns, such as grouting sleeve connection, slot connection and socket connection, cannot take into account both connection reliability and construction convenience. Contents of the invention [0003] In view of the above-mentioned technical problems, the present invention aims to provide a connection structure between caps and piers and a construction method thereof that can take into account both connection reliability and construction convenience. [0004] In order to solve t...
