Embodiment 1

[0085] Such as Figure 1-11 shown.

[0086]A prefabricated bridge pile assembly structure, including a pile foundation 1, a pier column 2, a first steel pipe column 51, and a second steel pipe column 6, the top of the pile foundation is provided with a socket, the first steel pipe column 51 is arranged in the socket, and the second The top part of the second steel pipe column 6 is located in the pier column 2, the part exposed from the bottom of the second steel pipe column 6 is the socket part 61, the top of the first steel pipe column 51 is open, and the inside is a hollow structure, and the second steel pipe column 6 is a solid structure , the shape of the first steel pipe column 51 and the second steel pipe column 6 are the same, the socket part 61 of the second steel pipe column 6 is inserted into the inside of the first steel pipe column 51, and the side wall of the first steel pipe column 51 forms an outward protrusion at several set positions 73, the side wall of the ...

Embodiment 2

[0118] Such as Figure 12 As shown, the difference between this embodiment and Embodiment 1 is: the grouting sleeve is arranged at the bottom of the pier column, the first anchoring steel bar extends out of the top of the pile connecting section 3 for a certain length, and the bottom of the main reinforcement 21 of the first pier column extends into the grouting In the sleeve, when the pier column and the pile foundation are connected, the grouting sleeve is aligned with the first anchoring steel bar, and then each grouting sleeve is grouted one by one.

[0119] Compared with Embodiment 1, the advantages of this embodiment are: the grouting sleeve is set on the top of the pile foundation, and when the prefabricated pier column 2 is poured with concrete, the retracted main reinforcement of the pier column is beneficial to the quality control of the concrete at the bottom of the pier column, which is beneficial to the quality control of the pier column. The protection of the bot...

Embodiment 3

[0121] A method for connecting a prefabricated bridge pile assembly structure, the specific steps are as follows:

[0122] The second steel pipe column 6 is connected with several second studs 64, the second pier column main reinforcement 62, and the fifth stirrup 63, and the concrete in the second steel pipe column 6 should be poured synchronously with the concrete of the pier column 2;

[0123] Binding and fixing the main reinforcement 21 of several first pier columns and the fourth stirrup 22, inserting one end of the second steel pipe column 6 into the reinforcement cage surrounded by the main reinforcement 21 of several first pier columns, and pouring the pier column 2;

[0124] The pile foundation 1 is arranged below the ground, and the pile foundation main reinforcement 11, some first anchor reinforcement bars 32, and some second anchor reinforcement reinforcement bars 57 are arranged at predetermined positions of the pile foundation, and are connected with the first stirr...

Abstract

The invention relates to a fabricated bridge pile-column assembled structure and a connecting method thereof. The fabricated bridge pile-column assembled structure comprises a pile foundation, a piercolumn, a first steel pipe column and a second steel pipe column; a socket is formed in the top of the pile foundation, and the first steel pipe column is arranged in the socket; the top of the secondsteel pipe column is located in the pier column, and the part, exposed out of the pier column, of the bottom of the second steel pipe column is provided with an inserting opening part; the top and the bottom of the first steel pipe column are open, and the first steel pipe column and the second steel pipe column are the same in shape; the inserting opening part of the second steel pipe column isinserted into the first steel pipe column, and convex parts are formed on a plurality of set positions of the side wall of the first steel pipe column; and inward-sunken parts are formed in the positions, opposite to the multiple convex parts, of the side wall of the second steel pipe column, the multiple convex parts and the multiple inward-sunken parts form a plurality of cavities, the cavitiesare parallel to the axial directions of the first steel pipe column and the second steel pipe column correspondingly, pins are arranged in the cavities, and a grouting material is press-injected intoa gap between the second steel pipe column and the first steel pipe column. The pile foundation and the pier column are quickly and accurately assembled and connected, the construction cost is lowered, and the construction difficulty is lowered.

Description

technical field [0001] The invention belongs to the technical field of highway bridges, and in particular relates to an assembled bridge pile structure and a connection method thereof. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] At present, in the field of industrial and civil construction, the development of prefabricated buildings is in full swing, but there are few implementation projects in highway bridges and culverts, and only exploratory experimental work has been carried out in certain projects in individual provinces and cities. General construction projects are mostly multi-layer structures, which are convenient for centralized transportation and hoisting, a...
