Problems solved by technology

However, the current design of hollow piers has defects such as complicated construction and high manpower and material resources, and it is still necessary to further reduce the weight and save materials.
[0003] In addition, none of the current pier types directly reflect the loads they bear

Embodiment Construction

[0020] According to the designed shape and size of the pier, the frame 2 of the enclosure structure 1 is made of metal materials, and then covered with a membrane 3 with waterproof capability and certain tensile capacity to form a complete enclosure structure 1 .

[0021] Also use the metal frame to add film to make the foundation 4 that is root-like divergence. The foundation 4 is embedded in the soil body 5 .

[0022] The foundation 4 can also be formed by pouring conventional reinforced concrete materials.

[0023] A liquid 6 is then injected into the interior of the envelope 1 .

[0024] Inside the envelope 1 , on top of the liquid 6 , a support 7 is mounted. 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 seals the liquid 6 within the enclosure structure 1 . A pressure sensor 9 capable of real-time monitoring of the pressure data of the liquid 6 is installed on the...

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 liquid load-bearing pier structure. Background technique [0002] The pier structures used on bridges currently mainly include solid piers, column piers, flexible piers, frame piers, and hollow piers. The common outstanding problems of these types of piers are that they rely entirely on rigid materials for load bearing, self-heavy, and materials are not fully utilized. Among them, the hollow pier is more reasonable in terms of force characteristics, and its self-weight is relatively light. It mainly has two forms: one is basically a solid gravity structure with a hollowed-out central part; the other is a hollow-shaped pier of reinforced concrete. However, the current design of hollow piers has defects such as complicated construction and high consumption of manpower and material resources, and it is still necessary to further reduce self-weight and save materials. [0003] In addition...
