Embodiment Construction

[0022] According to the designed shape and size of the bridge pier, the frame 2 of the enclosure structure 1 is made of metal materials, and then covered with a membrane 3 with waterproof and certain tensile capabilities to form a complete enclosure structure 1.

[0023] The same method of adding a metal frame to a film is used to make a root-like foundation 4. The foundation 4 is embedded in the soil body 5.

[0024] The foundation 4 can also be made by pouring conventional reinforced concrete materials.

[0025] Then, the liquid 6 is injected into the enclosure structure 1.

[0026] A support 7 is installed inside the enclosure 1 and above the liquid 6. The upper surface of the support 7 is connected with the upper structure 8 of the bridge, and the lower surface is in close contact with the liquid 6 and the liquid 6 is sealed in the enclosure structure 1. A pressure sensor 9 capable of monitoring the pressure data of the liquid 6 in real time is installed on the lower surface o...

Abstract

A new type pier structure with liquid bearing is composed of exterior-protected construction, liquid, bracket, pressure sensor and basic. The exterior-protected construction contains metal frame and film with liquid filling inside. The bracket connects with upside structure of bridge from upper, contacts liquid from bottom and closures liquid in exterior-protected construction entirely. Pressure sensor is located on below surface of bracket to monitor hydraulic pressure. The basic is below the exterior-protected construction and appears tree radiation. It can joint to exterior-protected construction as a whole, be composed of metal frame and film or be poured by reinforced concrete. The invention has merits of rational stress, convenient construction, saving materials, reducing deadweight, low cost and long life-span. It can also realize teal-time and long-distance monitoring on working conditions of piers. Monitoring data accumulated after operating have great value for calculating bridge and perfecting design theories.

Description

Technical field [0001] The invention relates to a bridge substructure, in particular to a new type of liquid bearing bridge pier structure. Background technique [0002] The pier structure adopted on the bridge currently mainly includes solid piers, column piers, flexible piers, frame piers, and hollow piers. The common prominent problem of these types of piers is that they rely entirely on rigid materials for load-bearing, self-weight, and materials that are not fully utilized. Among them, the hollow pier is more reasonable in terms of force characteristics, and its own weight is relatively light. It mainly has two forms: one is basically a solid gravity structure with a hollow center part; the other is a reinforced concrete hollow pier. However, the current hollow bridge pier design has disadvantages such as complicated construction and more manpower and material resources, and it is still necessary to further reduce its own weight and save materials. [0003] In addition, all ...
