Installation Technology of Basin Rubber Bearing of Cast-in-situ Bridge

Abstract

The invention introduces an installation process for cast-in-place bridge basin-type rubber bearings, which includes the following steps: 1) during construction, pouring the cushion stone concrete according to the height of the support; 2) when the cushion stone concrete reaches the design strength, Grind the backing stone and draw the centerline and sideline of the support; 3) Prepare several steel support piles of appropriate length, drill holes in the support stone, and insert the steel support piles into the holes as support points; 4) Adjust the steel support pile elevation; 5) Clean up the pad stone and reserve bolt holes; 6) Install the wooden strip frame on the outer edge of the support; 7) Install the bolts under the support in place, and conduct a trial installation of the support; 8) Prepare epoxy mortar and Pour it into the reserved bolt holes and evenly spread it on the pad stone, and install the support in time; 9) Remove the wooden strip frame on the outer edge of the support, and then install the bolts on the support; 10) Health preservation. The installation process of the present invention combines two fillings into one, which improves the installation accuracy, faster installation speed, and significantly improves the filling quality.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering construction, and specifically relates to an installation process of a cast-in-place bridge basin type rubber bearing. [0002] Background technique [0003] The bridge bearing is an important part of the beam bridge structure. The beam bridge is usually composed of piers, cover beams and platform caps. Set the force transmission device. With the development of road engineering, bridge girders and bridge supports are becoming larger and larger. At the same time, new requirements are constantly put forward for the bearing capacity and deformation capacity of bridge supports, and the technical requirements for their construction and installation are also increasing. However, due to the large bridge support and the limited operating space at the top of the pier column, it is often difficult for the bridge support to meet the engineering requirements during construction and leveling.
