Supporting device for civil bridge construction

Abstract

The invention discloses a supporting device for civil bridge construction, and relates to the technical field of civil construction. The supporting device includes a column pile, a retaining plate, amain diagonal brace and an auxiliary diagonal brace. The retaining plate is fixedly installed on one side of the column pile, the main diagonal brace is installed on the other side of the column pile,the auxiliary diagonal brace is rotatably installed at the bottom end of the main diagonal brace, and the tail end of the auxiliary diagonal brace and the bottom end of the main diagonal brace are both equipped with collars. When the supporting device is used as an inclined rod support, the main diagonal brace is in contact with the bottom surface of a foundation pit, a supporting pile is inserted into the collar at the bottom end of the main diagonal brace, the auxiliary diagonal brace abuts against the column pile, and the column pile is not prone to deformation and inclination under the action of three support points; and when the supporting device is used as an anchor support, the main diagonal brace is rotated to the ground outside the foundation pit, the auxiliary diagonal brace isin contact with the ground, the supporting pile is inserted into the collar at the tail end of the auxiliary diagonal brace, and the column pile is pulled. The supporting device can achieve switchingbetween the inclined rod support and the anchor support to meet site requirements, construction units are prevented from preparing different forms of support equipment in advance, and a large amount of cost is saved.

Description

technical field [0001] The invention relates to the technical field of civil engineering construction, in particular to a support device for civil engineering bridge construction. Background technique [0002] The excavation of the foundation pit in bridge construction is the first thing that needs to be carried out in the project process. After the foundation pit is excavated, the platform can be poured, and the bridge piers can be poured on the platform to support the prefabricated or cast-in-place beams. The support work during the excavation of the foundation pit has a great influence on the progress and quality of the excavation of the foundation pit. It is very important to choose the appropriate support method according to the site conditions and project requirements. [0003] At present, the commonly used foundation pit support methods include inclined column support, anchor support, concrete pouring pile and sprayed concrete support, etc. Since the depth of the foun...

[0004] However, the above two support methods are used alone, and most of the equipment used in them cannot be used in common in the two support methods, which requires the construction unit to prepare equipment for the two support methods. Choosing one of them will undoubtedly increase the cost of the construction unit
