A support device for civil bridge construction

Abstract

The invention discloses a support device for civil bridge construction, which relates to the technical field of civil construction, and comprises column piles, soil retaining boards, main diagonal braces and auxiliary diagonal braces, the soil retaining boards are fixedly installed on one side of the column piles, and the column piles The main diagonal brace is installed on the other side, the auxiliary diagonal brace is rotatably installed at the bottom end of the main diagonal brace, and a collar is installed at the end of the auxiliary diagonal brace and the bottom end of the main diagonal brace. When used as a diagonal support, the main diagonal brace contacts the bottom of the foundation pit, and the supporting pile is inserted into the ring at the bottom of the main diagonal brace, and the auxiliary diagonal brace is supported on the column pile, and the column pile is under the action of three support points It is not easy to deform and tilt. When used as an anchor support, the main diagonal brace is rotated to the ground outside the foundation pit, so that the auxiliary diagonal brace touches the ground, and then the supporting pile is inserted into the collar at the end of the auxiliary diagonal brace to pull the column pile. The support device of the present invention can be switched between slanting rod support and anchor support to meet site requirements, avoiding the construction unit from preparing different forms of support equipment in advance, and saving a lot of cost.

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
